[0001] The present application is a continuation of pending U.S.
application Ser. No. 12/030,013, filed on Feb. 12, 2008, which is a
continuation of U.S. application Ser. No. 11/837,323, filed on Aug.

disclosures of which are incorporated herein by reference.
FIELD OF THE INVENTION
[0002] The present invention relates to the field of wiring using
outlets, and, more specifically, to an add-on module for adding
functionality to such outlets.
BACKGROUND OF THE INVENTION
[0003] Outlets
[0004] The term "outlet" herein denotes an electro-mechanical
device, which facilitates easy, rapid connection and disconnection
of external devices to and from wiring installed within a building.
An outlet commonly has a fixed connection to the wiring, and
permits the easy connection of external devices as desired,
commonly by means of an integrated connector in a faceplate. The
outlet is normally mechanically attached to, or mounted in, a wall
or similar surface. Non-limiting examples of common outlets
include: telephone outlets for connecting telephones and related
devices; CATV outlets for connecting television sets, VCR's, and
the like; outlets used as part of LAN wiring (a.k.a. structured
wiring) and electrical outlets for connecting power to electrical
appliances. The term "wall" herein denotes any interior or exterior
surface of a building, including, but not limited to, ceilings and
floors, in addition to vertical walls.
[0005] Rear part of an outlet (or module) refers herein to the side
facing the wall after installation, and commonly also comprises the
connector to the in-wall utility wiring. Front part refers to the
opposing side commonly facing the room, and commonly comprising
connectors for coupling to the utility wiring.
[0006] The terms "data unit", "computer" and "personal computer"
("PC") are used herein interchangeably to include workstations,
Personal Digital Assistants (PDA) and other data terminal equipment
(DTE) with interfaces for connection to a local area network, as
well as any other functional unit of a data station that serves as
a data source or a data sink (or both).
[0007] LAN Environment.
[0008] FIG. 1 shows a typical prior art LAN environment 10. Such a
network commonly uses 10BaseT or 100BaseTX Ethernet IEEE802.3
interfaces and topology, and features a hub 11 as a concentrating
device, into which all devices are connected. Devices are connected
to the hub 11 by data connectors 14a, 14b, and 14c, which are
housed within network outlets 15a, 15b, and 15c respectively.
Connections to the hub 11 are via cables 13a, 13b, and 13c
respectively. Data connectors 14a, 14b, and 14c may be, for
example, type RJ-45 connectors; and cables 13a, 13b, and 13c may
be, for example, Category 5 cabling. Such configuration is
described, for example, in EIT/TIA-568 and EIA/TIA-570. The data
portion of network 10 uses data units (which may be computers) 7a,
7b, and 7c, which connect to network connectors 14a, 14b, and 14c
via cables 16a, 16b, and 16c, respectively. A server 12 may also be
connected to the hub 11, and can perform the external connection
functionality, as well as other server functions as applied in the
art.
[0009] Although FIG. 1 refers to the hub 11 as a concentrating
device, it is to be understood that any type of device having
multiple network interfaces and supporting a suitable connectivity
can be used, non-limiting examples of which include shared hubs,
switches (switched hubs), routers, and gateways. Hence, the term
"hub" herein denotes any such device without limitation.
Furthermore, network 10 can be a packet-based network, either
in-building or distributed, such as a LAN or the Internet.
[0010] Home Networking.
[0011] Most existing offices and some of the newly built buildings
facilitate the network structure of network 10. However,
implementing such a network in existing buildings typically
requires installation of new wiring infrastructure. Such
installation of new wiring may be impractical, expensive and
problematic. As a result, many technologies (referred to as "no new
wires" technologies) have been proposed in order to facilitate a
LAN in a building without adding new wiring. Some of these
techniques use existing utility wiring installed primarily for
other purposes such as telephone, electricity, cable television
(CATV), and so forth. Such approach offers the advantage of being
able to install such systems and networks without the additional
and often substantial cost of installing separate wiring within the
building.
[0012] The technical aspect for allowing the wiring to carry both
the service (such as telephony, electricity and CATV) and the data
communication signal commonly involves using FDM technique
(Frequency Division Multiplexing). In such configuration, the
service signal and the data communication signals are carried
across the respective utility wiring each using a distinct
frequency spectrum band. The concept of FDM is known in the art,
and provides means of splitting the bandwidth carried by a medium
such as wiring. In the case of a telephone wiring carrying both
telephony and data communication signals, the frequency spectrum is
split into a low-frequency band capable of carrying an analog
telephony signal and a high-frequency band capable of carrying data
communication or other signals. Such a mechanism is described, for
example, in U.S. Pat. No. 4,785,448 to Reichert et al., and is also
widely used in xDSL systems, primarily Asymmetric Digital
Subscriber Loop (ADSL) systems.
[0013] Either in the case of FDM or any other technique, the wiring
system is commonly required to support connection of a data unit to
the data communication signal carried over the medium. Furthermore,
it is commonly required that such a connection will make use of a
standard interface having standard data communication connector.
One approach is to use dedicated stand-alone, desktop style adapter
device, connected between existing outlet and the data unit. Other
approaches are described herein.
[0014] Functional Outlet Approach.
[0015] This approach involves substituting the existing service
outlets with `network` active outlets. Outlets in general (to
include LAN structured wiring, electrical power outlets, telephone
outlets, and cable television outlets) have evolved as passive
devices being part of the wiring system house infrastructure and
solely serving the purpose of providing access to the in-wall
wiring. However, there is a trend towards embedding active
circuitry in the outlet in order to use them as part of the
home/office network, and typically to provide a standard data
communication interface. In most cases, the circuits added serve
the purpose of adding data interface connectivity to the outlet,
added to its basic passive connectivity function.
[0016] An outlet supporting both telephony and data interfaces for
use with telephone wiring is disclosed in U.S. Pat. No. 6,549,616
entitled `Telephone outlet for implementing a local area network
over telephone lines and a local area network using such outlets`
to Binder. Such outlets are available as part of NetHome.TM. system
from SercoNet Inc. of Southborough, Mass. USA.
[0017] Another telephone outlet is described in U.S. Pat. No.
6,216,160 to Dichter, entitled `Automatically configurable computer
network`. An example of home networking over CATV coaxial cables
using outlets is described in WO 02/065229 published 22 Aug. 2002
entitled: `Cableran Networking over Coaxial Cables` to Cohen et al.
Such outlets are available as part of HomeRAN.TM. system from TMT
Ltd. of Jerusalem, Israel. Outlets for use in conjunction with
wiring carrying telephony, data and entertainment signals are
disclosed in US Patent Application Publication US2003/0099228 to
Alcock entitled `Local area and multimedia network using radio
frequency and coaxial cable`. Outlets for use with combined data
and power using powerlines are described in US Patent Application
Publication US2003/0062990 to Schaeffer et al. entitled `Powerline
bridge apparatus`. Such power outlets are available as part of
PlugLAN.TM. by Asoka USA Corporation of San Carlos, Calif. USA.
[0018] While the active outlets have been described above with
regard to networks formed over wiring used for basic services (e.g.
telephone, CATV and power), it will be appreciated that the
invention can be equally applied to outlets used in networks using
dedicated wiring. In such a case, the outlet circuitry is used to
provide additional interfaces to an outlet, beyond the basic
service of single data connectivity interface. For example, it may
be used to provide multiple data interfaces wherein the wiring
supports single such data connection. An example of such outlet is
the Network Jack.TM. product family manufactured by 3Com.TM. of
Santa-Clara, Calif., U.S.A. In addition, such outlets are described
in U.S. Pat. No. 6,108,331 to Thompson entitled `Single Medium
Wiring Scheme for Multiple Signal Distribution in Building and
Access Port Therefor` as well as U.S. Patent Application US
2003/0112965 Published Jun. 19, 2003 to McNamara et al. entitled
`Active Wall Outlet`.
[0019] While the active outlets have been described with regard to
outlets and networks based on conductive media such as wires and
cables, it will be appreciated that such outlets are equally
applicable in the case wherein the network medium is
non-conductive, such as fiber-optical cabling. Active outlets
supporting data interfaces and based on fiber optic cabling are
described in U.S. Patent Application US 2002/0146207 Published Oct.
10, 2002 to Chu, entitled `Fiber Converter Faceplate Outlet`, as
well as in U.S. Pat. No. 6,108,331 to Thompson entitled `Single
Medium Wiring Scheme for Multiple Signal Distribution in Building
and Access Port Therefor`. As such, the term `wiring` as used in
this application as well as in the appended claims should be
interpreted to include networks based on non-conductive medium such
as fiber-optics cabling.
[0020] While the outlets described above use active circuitry for
splitting the data and service signals, passive implementations are
also available. An example of such passive outlet is disclosed in
PCT Publication WO 02/25920 to Binder entitled `Telephone
communication system and method over local area network wiring`.
Such outlets are available as part of the etherSPLIT.TM. system
from QLynk Communication Inc. of College Station, Tex. USA.
[0021] The described above outlets are complete and self-contained
devices. As such, they can be easily installed in new houses
instead of regular passive simple outlets. However, such solutions
are not appropriate in the case of retrofitting existing wiring
systems. In most cases, any such modification will require
dismantling the existing outlets and installing the new ones having
the improved features. Such activity is cumbersome, expensive and
will often require professional skill. Furthermore, owing to safety
aspects involved while handling hazardous voltages (such as in the
powerlines and telephone lines), local regulations may require only
certified personnel to handle the wiring, making it expensive and
militating against a do-it-yourself approach.
[0022] Furthermore, as the technology and environment change in
time, a need to upgrade, modify or change the outlet
functionalities, features and characteristics may arise. For
example, the data interface may need to be upgraded to interconnect
with new standards. In another example, the circuitry may need to
be upgraded to support higher bandwidth. Similarly, management and
Quality of Service (QoS) functionalities may need to be either
introduced or upgraded. In yet another examples, additional
functionalities and interfaces may need to be added. Using complete
self-contained outlets as a substitute to the existing ones also
introduces the disadvantages described above.
[0023] Plug-in Device.
[0024] One approach to adding functionality to existing outlets is
by using a plug-in module. A pictorial view of such a module 20
suitable for powerlines connection is shown in FIG. 2. The module
plugs into a regular power outlet using prongs 22a and 22b, and
provide access to a data unit via data connector 21 (shown as RJ-45
used for 10/100 Base-T IEEE802.3 interface). Optional visual
indicators 23a, 23b and 23c may also be employed. The prongs 22a,
22b are used for both the electrical connection and for the
mechanical attachment of the unit 20 to the power outlet. Such
plug-in modules are described in US Patent Application Publication
US 2002/0039388 to Smart et al. entitled `High data-rate powerline
network system and method`, US Patent Application Publication US
2002/0060617 to Walbeck et al. entitled `Modular power line network
adapter` and also in US Patent Application Publication US
2003/0062990 to Schaeffer, J R et al. entitled `Powerline bridge
apparatus`. Such a module using HomePlug.TM. technology are
available from multiple sources such as part of PlugLink.TM.
products by Asoka USA Corporation of San Carlos, Calif., USA.
HomePlug is a trademark of HomePlug Powerline Alliance, Inc. of San
Ramon, Calif., USA.
[0025] However, such plug-in modules are known only with regards to
power outlets, and are not available for telephone or CATV outlets.
Furthermore, since the outlets in general, including power outlets,
were not designed to offer any mechanical support beyond a plug
connection, such plug-in modules are not mechanically secured to
the wall/outlet, hence such attachment is not considered
sustainable and reliable. Furthermore, such plug-in modules are
bulky in appearance and not aesthetic.
[0026] There is thus a widely recognized need for, and it would be
highly advantageous to have, a method and system for allowing
reliable, easy and simple upgrading of outlets, preferably without
requiring professional installation.
SUMMARY OF THE INVENTION
[0027] It is therefore an object of the invention to provide a
method and system for allowing easy and simple upgrading of
outlets, preferably without requiring professional installation. An
add-on module is used for providing additional functionality to the
existing outlet.
[0028] The invention describes an add on module for adding
functionality to outlets serving existing wiring such as telephone,
power and CATV and dedicated wiring such as LAN wiring
(collectively `service wiring`, `service outlet`). Non-conductive
infrastructure such as fiber optics based is also included.
[0029] The add-on module (or `module` herein) is both electrically
connected and mechanically attached to the existing outlet. The
mechanical attachment may be permanent or detachable, wherein the
latter may be by hand or with specific tools. The electrical
connection may use a mechanically fixed connector or tethered
connector (`dongle`). In one aspect of the present invention, the
module is mounted on the existing outlet by means of attaching to
the outlet surface. Such attachment may use suction force, adhesive
materials (e.g. glue) or VELCRO. VELCRO is a registered trademark
of Velcro Industries B.V. In another aspect of the present
invention, the module is attached to the sides of the outlets. Such
attachment may use pressure or eccentric levers or securing strap.
In another aspect of the present invention, the module is attached
by inserting tabs between the outlet and the wall. In another
aspect of the present invention, the module is attached by
fastening screws, wherein the screws are inserted via the module
and the holes in the outlets.
[0030] In another aspect of the present invention, the module is
attached to the outlet by using a mechanical adapter. The adapter
is attached to the outlet, and the module is independently attached
to the adapter. The attachment of the adapter to the outlet may use
any of the above described mechanical attachment methods.
Similarly, the attachment of the module to the adapter may also use
any of the described above methods, as well as latching, using
magnetic forces and locking.
[0031] In another aspect of the present invention, the module is
used in conjunction with a data network carried over wiring
simultaneously serving basic service is described. The basic
service may be telephony carried over telephone wiring, power
carried over powerlines and CATV carried over coaxial cable
television infrastructure, as well as data networking using
dedicated LAN wiring. In such a case, the outlet comprises a
data/service splitter/combiner for separating the basic service
signal carried over the wiring, and allowing access thereto by a
respective connector (telephone, power or CATV connector). The data
signal is separated by a respective medium modem, and coupled to a
data unit via a connector coupled to an adapter. A hub and
management may be optionally employed as explained above.
[0032] In another aspect of the present invention, the module
further comprises an adapter providing an analog interface such as
analog video, analog voice and telephone.
[0033] In another aspect of the present invention, a non-wired
interface, such as light (e.g. infrared), audio or radio frequency
(wireless) based, is used for coupling to a data unit. In such a
case, the data unit connector is substituted by an appropriate
non-wired transceiver.
[0034] In conjunction with a wired Local area Network (LAN), a
multi-port active network outlet is described. Such outlet
comprises a transceiver to allow data communication over the
network wiring. The outlet supports one or more connectors, each
allowing for data unit coupling to the data communication signal by
a respective transceiver. Furthermore, the outlet comprises an
adapter and connected respective connector allowing for coupling a
data unit to the data communication signal via a distinct
interface. The outlet further optionally comprises a hub for the
multiple data streams to be coupled. An optional
management/processing functionality may also be embedded in the
outlet.
[0035] In another aspect of the present invention, the module
comprises passive components for the networking functionality. In
another aspect of the present invention, the module comprises
active components for the provided functionality (e.g. networking).
In the latter case, the active circuitry within the module needs to
be power fed in order to work properly. The module may be locally
powered by a dedicated connection to a local power source (e.g. AC
power, directly or via AC/DC converter). Alternatively, the module
is power fed from a power signal carried over the wiring. In
another aspect of the present invention, the module is powered by
an appliance connected thereto.
[0036] In another aspect of the present invention, the module is
used to provide non-networking functionalities. In such a case,
part or all of the functionalities of a device which normally
connects to the outlet, are integrated into the module. In another
aspect of the present invention, the module is used to provide both
electrical coupling to the service outlet as well as mechanical
support. Such mechanical support can be used to hold and attach
(and detach) appliances and devices to the module. The electrical
connection may include only connection to the service signal (such
as AC power in the case of power module). In other embodiments, the
electrical connection may include coupling to the data signal
carried over the service wiring (such as telephone module providing
coupling to a data signal carried over telephone wiring). Other
embodiments may include coupling the mechanically attached
appliances to both the service and data signals carried over the
wiring. For example, mobile and handheld appliances such as PDA and
cellular telephones are described. In one aspect of the invention,
such a module is used to add service connections to an outlet.
[0037] In one aspect of the present invention, a power module is
described comprising power related functionalities such as multiple
AC power sockets, power switch, lighting dimmer, safety means (e.g.
fuse), lightning protection, visual or audible indicators, load
control (such as fan speed control), timer switching, filters (e.g.
noise filters) and sensors (such as security, heat and flood
sensors). In one aspect of the present invention, a power module is
described comprising power converter appliances such as AC/DC
converters and chargers, such as PDA and cellular telephone
chargers. In the case of chargers (such as for PDAs and cellular
telephones), the module may include the cradle functionality (e.g.
mechanical housing) for providing a mechanical support during
charging. In one aspect of the present invention, a power module is
described for providing a coupling to the data signal carried over
the power wiring.
[0038] In one aspect of the present invention, a telephone module
is described comprising telephone related functionalities such as
multiple telephone jacks, filters (such as ADSL/HomePNA micro
filters and noise filters), safety means (e.g. fuse), lightning
protection, visual or audible indicators and sensors (such as
security, heat and flood sensors). In one aspect of the present
invention, a telephone module is described comprising power
converter appliances and chargers, such as PDA and cellular
telephone chargers. In the case of chargers (such as for PDAs and
cellular telephones), the module may include the cradle
functionality (e.g. mechanical housing) for providing a mechanical
support during charging. In one aspect of the present invention, a
telephone module is described for providing a coupling to the data
signal carried over the telephone wiring. Other telephone
appliances which may be integrated (in part or in full) or
mechanically supported by a telephone module are described such as
answering machines, modems (such as dial up or xDSL), telephone set
(either landline or cordless) and caller-ID.
[0039] In one aspect of the present invention, a CATV module is
described comprising telephone related functionalities such as RF
splitter, filters, safety means (e.g. fuse), lightning protection,
visual or audible indicators and sensors (such as security, heat
and flood sensors). CATV Related appliances which may be integrated
(in part or in full) or mechanically supported by a CATV module are
described such as cable modem, set top box, VCR. DVD, DVR,
television set, DRM devices.
[0040] In another aspect of the present invention, the module
comprises visual (or audible or both) indicators for monitoring the
module status. Such indicators may indicate power availability,
proper operation of part or all of the circuitry included in the
module, communication status (of either the wiring communication or
the module connected device or both) and the status of the service
signal.
[0041] In another aspect of the present invention, the module
provides intangible added functionality to an outlet such as
improved aesthetics or any other way of pleasing the eye.
Non-limiting examples are color, texture and artistic shaping of
the module.
[0042] It is understood that other embodiments of the present

DETAILED DESCRIPTION OF VARIOUS EMBODIMENTS
[0110] The principles and operation of a network according to the
present invention may be understood with reference to the drawings
and the accompanying description. The drawings and descriptions are
conceptual only. In actual practice, a single component can
implement one or more functions; alternatively, each function can
be implemented by a plurality of components and circuits. In the
drawings and descriptions, identical reference numerals indicate
those components that are common to different embodiments or
configurations.
[0111] Module.
[0112] The present invention relates to a module that both connects
electrically to an existing outlet and is also mechanically
attached thereto. For the sake of simplicity, the invention will be
herein first described with respect to a module for use in
conjunction with a telephone outlet, in order to provide the
electrical connection thereto. Front and rear views of a basic
exemplary telephone module 30 are respectively shown in FIGS. 3b
and 3a. An RJ-11 telephone plug 31 is mounted on a rear surface of
the module 30 so as to protrude outwardly therefrom for connecting
to the outlet RJ-11 telephone socket. On the front surface of the
module there are provided two RJ-11 sockets 32a and 32b, commonly
in order to retain the telephone connectivity, and a RJ-45
connector 34 for data communication connection (such as common
10/100Base-T Ethernet interface). The module may also employ visual
indicators such as 33a and 33b.
[0113] Surface Attachment.
[0114] In one or more embodiments of the present invention, the
module is mechanically attached to the front surface of an existing
outlet. This may be done using suction, for example.
[0115] In one or more embodiments of the present invention, the
mechanical attachment uses suction for the mechanical attachment.
FIG. 4a shows such a module where suction is used to attach the
module to the front surface of an existing outlet. Added to the
basic module 30, the module 40 comprises two suction pads 41a and
41b, which upon being pressed against the existing outlet 42
surface as shown in FIG. 4b, become attached thereto.
Simultaneously, the connector 31 is mated with connector 43. While
two suction units 41a and 41b are illustrated, any number of such
units may be used providing that sufficient suction is created to
support the weight of the module. A pictorial view of such a module
40 is shown in FIG. 4c, further showing a release lever 44 so that
depressing the release lever 44 releases the connector 31 in order
to detach the module 40 from the outlet 42.
[0116] According to another embodiment of the invention, the module
is mechanically attached to the front surface of an existing outlet
using adhesive material such as glue or adhesive stickers. The
adhesive material may be applied to all or part of the surface area
of the existing outlet, wherein contact with the module is
required. FIGS. 5a and 5b show such an attachment of a module 50 to
an outlet 42, wherein glue is applied to a specific area 51 (marked
as shaded) of the module 50 and/or to the opposing surface 52 of
outlet 42. In most cases, such attachment is permanent.
[0117] Alternatively, releasable mechanical attachment can be
achieved by using so called "hook and loop" fasteners, such as
VELCRO, or any other releasably joined surfaces. In this approach
mating Velcro strips are attached to both the existing outlet and
the module (e.g. by means of adhesives) on opposing and contacting
surfaces, such that mechanical attachment is formed by juxtaposing
the mating strips. The module can be separated from the outlet by
applying enough force to release the VELCRO fastener.
[0118] As described above, the present invention uses two
approaches for mechanical attachment, namely permanent and
detachable. In the permanent solution, such as the gluing described
above, the module is attached to the existing outlet and cannot be
easily detached therefrom, thus creating a joined outlet/module
unit. In the detachable approach, where, for example, suction or
VELCRO are used, the module may be detached and separated from the
outlet, allowing for returning to the pre-attachment state. The
separation of the module from the outlet may be easy and bare
handed (such as in the case of Velcro, for example), or use
standard or specific tools (e.g. screwdriver).
[0119] The electrical connection between the existing outlet and
the module is made via utility connectors, such as RJ-11 jacks for
telephony as described above. In one more embodiments of the
present invention, the connector also aids and enhances the
mechanical attachment. As described above, the RJ-11 plug is fixed
and attached to the module, thus providing the additional
mechanical support. However, some connectors are not designed for
such mechanical stress and may be harmed in such usage or affect
the reliability of the electrical connection. In one or more
embodiments of the present invention, the connector is used solely
for the electrical connection. In such a case, the mating connector
in the module is not fixed to the enclosure but rather connects via
a cable (`dongle` approach). An exemplary configuration is shown in
FIG. 6 illustrating a RJ-11 plug 31 connected to the module 60 (a
portion of whose rear part is shown) via a short cable 61. Mounting
of a module on an existing outlet typically requires connecting the
connector in the module to the mating connector in the outlet,
followed by the mechanical attachment. In the case wherein the
attachment is not permanent, the module connector should be
unplugged as part of the separation process.
[0120] Side Clamping.
[0121] In accordance with other embodiments of the invention, side
clamping is employed whereby the module is attached by means of
modules parts pressed against the sides of the existing outlets.
Such a configuration is illustrated in FIGS. 7a and 7b. A module 70
shown is based on basic module 30 described above, further having
movable side bars 71a and 71b that may be splayed apart and
released so as to engage respective edges 72a and 72b of the outlet
42. The recesses 71a and 71b may be resiliently mounted on the
outer surface of the outlet so as to be capable of mutual outward
separation. Alternatively, the edges 72a and 72b of the outlet 42
may be provided with an outwardly protruding ridge that engages the
respective recesses 71a and 71b, in which case it is sufficient to
rely on the elasticity of the outlet casing to ensure a snap fit
between the recesses and the respective ridges. Springs may be used
to provide the pressing forces. The module 70 attached to outlet 42
is shown in FIG. 7b. Although in the figures, the peripheral
recesses 71a and 71b are mounted on side edges of the outlet, they
can equal well be mounted on upper and lower edges thereof.
[0122] FIG. 8a shows a module 80 having a pair of eccentric levers
81a and 81b, constituting an eccentric level mechanism. As shown in
the detailed view 82 in FIG. 8b, the lever 81b may swivel about
axis 83. Upon attaching the module 80 to the outlet 42 as shown in
FIG. 8c and pushing the levers in a first direction (e.g. upward),
the levers 81a and 81b are pressed against respective sides
surfaces 72a and 72b of the outlet 42 thus `locking` the module 80
to the outlet 42. Rotating the levers 81 in a second, opposite
direction (e.g. downward), unlocks the module 80 from the outlet
42.
[0123] While the invention has been described with regard to a
module for installing onto a telephone outlet, it will be
appreciated that the invention equally applies to other outlets,
such as power and CATV outlets. An example of a module 90 using
side clamping as described above is shown in FIG. 9a. Similar to
module 70 described above, the module 90 comprises a data connector
34, indicators 33a and 33b, as well as movable side bars 71a and
71b. Instead of the telephone jacks 32a and 32b of module 70, an RF
connector 91 is employed. The connector 91 may be F-Type connector
common in CATV system in North America, BNC type or any other. As
shown in FIG. 9b, the module 90 is attached to a CATV outlet 92
having RF connector 99, which may be F-Type jack common in CATV
system in North-America, BNC type or any other coaxial cable
connector. In a similar manner as described above, the module 90 is
attached and secured to the outlet 92 via peripheral recesses 71a
and 71b that engage respective side edges 72a and 72b of the outlet
92.
[0124] FIG. 9c shows a snap-on module 90 having an RF plug 94 that
is flexibly mounted via a short cable 95. However, the plug may
equally well be rigidly mounted to the outlet.
[0125] An example of a module for use with power outlets is shown
as module 100 in FIG. 10a. Serving in conjunction with power
delivery wiring the module comprises a power receptacle 101 shown
to support two prong appliances common in North America. Other
features are similar to the modules described above. The module 100
can snap onto the power outlet 102, as shown in FIG. 10b,
connecting to an outlet power receptacle 93 and mechanically
attached to its side surfaces 72a and 72b as explained above. While
a 2-prong outlet and plug are described, it will be appreciated
that the same applies for 3-prong outlets and plugs.
[0126] Snap Locking.
[0127] In one or more embodiments according to present invention
the module is attached to the existing outlet by inserting a tab
between the outlet faceplate and the wall. Such a module 110 is
shown in FIG. 11a. The module 110 is based on the module 30,
wherein two swing latches 111a (shown in FIG. 11d) and 111b are
added, as shown in FIG. 11b. Upon attachment of the module 110 to
outlet 42, a snap lock action is achieved by swinging the latches
111a and 111b, such that the latches are forced between the outlet
42 and a wall on which the outlet 42 is mounted. Such action
attaches the module 110 to the outlet 42 as shown in FIG. 11 c.
FIG. 11 d shows a detailed view 112 of the latch 111a. In this
example, no simple releasing mechanism of latches 111 is
described.
[0128] Band/Strap Securing.
[0129] While the invention has been described with regard to the
attachment means being an integral part of the module, it will be
appreciated that the invention equally applies to the cases wherein
the mechanical attachment means are decoupled from both the
existing outlet and the module. Such an approach is now
demonstrated herein by way of non-limiting example with regard to
the use of a securing strap or band.
[0130] A U-shaped securing band or strap 120 is illustrated in
FIGS. 12a and 12b. The band 120 is stiff yet provides some degree
of elasticity, and comprises two rigid abutments 121a and 121b. The
band 120 is used to urge the module 30 against the outlet 42,
wherein the abutments 121a and 121b abut a rear surface of the
outlet 42, thus securing the mechanical attachment.
[0131] FIG. 13a shows a similar band 130 whose abutments 121a and
121b are articulated to respective levers 131a and 131b. A module
30 attached to an outlet 42 using the band 130 is illustrated in
FIG. 13b and in FIG. 13c. The levers 131a and 131b may be used to
latch and secure the surfaces 121a and 121b in place, or
alternatively may be used for releasing their pressure, thus
enabling easy and quick separation of the module 30 from the outlet
42.
[0132] While the invention has been described with regard to a
limited number of attachment techniques such as surface attachment,
side clamping, snap locking and strap securing, it will be
appreciated that the invention applies equally to other methods and
means supporting mechanical attachment and electrical connection of
a module to an outlet. Furthermore, it will be appreciated that any
combination of the above methods or any combination of any one
described method with another method falls within the scope of the
present invention.
[0133] Fastening Screws
[0134] Common existing outlets are comprised of two parts: a
plastic faceplate mounted at the front of the outlet, and the
outlet body which is secured to the wall. In most cases, the
faceplate is fastened to the outlet body by one or two screws. In
one or more embodiments, screws are used for securing the module to
the outlet. If desired, the same screws may be used for securing
the faceplate to the outlet body. A faceplate 42 of an outlet with
screws removed is shown in FIG. 14a, illustrating threaded
apertures 141a and 141b. The Figure also shows a module 145, having
two thru-holes 142a and 142b. Screws 143a and 143b are inserted
through the respective thru-holes to the module 145 so as to
threadably engage the threaded apertures 141a and 141b in the
outlet 42 thereby securing the module 145 to the outlet body. The
screws 143 are longer than the ones used just for securing the
outlet faceplate alone.
[0135] Upon tightening the screws 143 the module 145 is
mechanically attached to the outlet 42 as shown in FIG. 14b.
Unscrewing the screws 143 allows the separation of the module 145
from the outlet 42. It should be noted that in this embodiment,
faceplate 42 of the outlet may be eliminated upon attaching the
module to the outlet.
[0136] Adapters.
[0137] The invention has been described above with respect to the
case wherein the module directly mounts on the existing outlet,
without using any intermediary device (except adhesives). However,
in many cases it may be beneficial to use a discrete mechanical
adapter between the outlet and the module. When using such
mechanical adapter, the adapter is to be attached to both the
existing outlet and to the module. One advantage of using such
adapter is the capability of mounting the same module to various
outlet configurations, using different adapters for each outlet
type. Another advantage involves the capability to easily exchange
modules types, while obviating the need to replace the mechanical
adapter.
[0138] In the configuration of using a mechanical adapter, two
mechanical attachments are involved. One is the attachment of the
adapter to the existing outlet, and the other involves attaching
the module to the mechanical adapter. The above mechanical
attachments are of course in addition to the need for the
electrical connection of the module to the outlet. According to the
invention, the two attachments, namely the outlet/adapter and the
adapter/module are fully decoupled and independent. For example,
each attachment may be permanent or removable. Furthermore, in some
applications the outlet/adapter attachment will be executed first,
while other applications may call for the adapter/module attachment
to be performed first.
[0139] Each or both of the outlet/adapter and adapter/module
attachments may use any of the above described attachment methods,
such as side clamping, surface attachment, snap locking and
strap/band securing, or any other attachment methods and means. For
the sake of simplicity, an example describing only adapter/module
attachments will now be described.
[0140] Latch/Snap-Fit Adapter.
[0141] An exemplary latch/snap-fit adapter 150 according to the
present invention is illustrated in FIG. 15a. In this example, the
mechanical adapter 150 is attached to the outlet using surface
attaching, such as adhesives. An opening 151 in the adapter 150
allows access to the existing outlet jack. Two snap-fit connectors
are provided each comprising a flexible tab having a respective
outwardly projecting lug 152a and 152b on outermost faces thereof
for attaching to the snap-on module. The adapter 150 is first
attached (e.g. glued) to the existing outlet 42 as shown in FIG.
15b. The adapter 150 is used in conjunction with module 155 shown
in FIG. 15b. The module 155 has apertures, of which only one 156a
is shown, in opposite surfaces and being dimensioned for engaging
corresponding ones of the lugs 152a and 152b whereby the module 155
is snap-fitted on to the outlet 42 as shown in FIG. 15c.
[0142] While the above attachment is described regarding first
attaching the adapter 150 to the outlet 42, in a similar way the
first action may be attaching the adapter 150 to the module 155 as
shown in FIG. 15d. In such case, the combined module 155/adapter
150 is then attached (e.g. glued) to the existing outlet 42.
[0143] It is apparent that such module 155/adapter 150 attachment
may be permanent or separable. In the latter case, pushing or
depressing the lugs 152 will release the module 155 from the
combined outlet 42/adapter 150 assembly.
[0144] While the above configuration has been illustrated showing
vertically located slots, it will be apparent that horizontal
snap-fit connectors may equally well be used, as are shown in the
adapter 160 depicted in FIGS. 16a to 16d.
[0145] While adapters 150 and 160 above have been described as each
having two support attachment points, it will be appreciated that
this is not intended to be limiting and more than two connectors
may be used. Thus, FIG. 17a shows an exemplary adapter 170
supporting four snap-fit connectors, of which only two 171a and
171b are shown, attached to an outlet 42. Two snap-fit connectors
171a and 171b are located on the upper surface and two snap-fit
connectors (not shown) are located on the lower surface, thereby
providing four supporting points in total. A module 175 shown in
FIG. 17b comprises respective apertures of which only two 176a and
176b are shown, for engaging the snap-fit connectors in the
adapter, resulting in a combined module 175/adapter 170/outlet 42
as shown in exploded view in FIG. 17b, and pictorially in FIGS. 17c
and 17d. In one or more embodiments according to the present
invention, two of the snap-fit connectors (e.g. the two lower ones
not shown in the Figures) may be used as axis and guiding means,
aiding the locking of the other pair 171a and 171b.
[0146] Bayonet (Rotating) Latch.
[0147] In one or more embodiments according to the present
invention, a rotating latch mechanism is used, as shown in FIG.
18a. The figure illustrates an adapter 180 comprising a
receptacle/socket 181. The adapter 180 is releasably secured to a
module 185 using a bayonet latch comprising a rotating plug 186
having two positions, namely `Open` and `Locked` for bayonet
fitting to the socket 181. As shown in FIG. 18b, in the `"Open"
position the rotating plug 186 can freely move in and out of the
receptacle/socket 181. The adapter 180 is shown in FIG. 18c
attached to outlet 42. Module 185 spaced from outlet 42 prior to
mounting is shown in FIG. 18d. Upon attaching the module 185 to the
combined outlet 42/adapter 180 assembly, the rotating plug 186 is
inserted into socket 181 and twisted from the front (as shown in
FIGS. 18c and 18f) to the `Locked` position using a screwdriver, a
coin or the like, thereby bayonet locking of the plug 186 to
receptacle 181, and attaching the module 185 to outlet 42. The
locked configuration is shown in FIG. 18g. Rotation the plug 186
back to the `Open` position will release the module 186 from the
adapter 180/outlet 42 assembly. While a single plug/receptacle pair
has been described, it will be appreciated that two or more such
bayonet latches may be used, resulting in added stability and
security.
[0148] Magnetic Adapter.
[0149] While the invention has been described with regard to using
mechanical structures, forces, moments and mechanisms, it will be
appreciated that the invention equally applies to any other
attaching techniques such as using magnetic forces. An example of
such embodiment is shown in FIG. 19a. The module 190 comprises two
magnets 191a and 191b. As illustrated in FIG. 19b, magnetic or
magnetizable metal discs 192a and 192b, serving as the adapter, are
attached (e.g. glued) to the outlet 42, in registration with the
respective module 190 surfaces 191. The magnets/discs 191a and 191b
are magnetically attached to the respective metal discs 192a and
192b, thus attaching the module 190 to the outlet 42. It will be
appreciated that both 191 and 192 may be magnetic bodies having
opposite polarities. Similarly, the module 190 may comprises metal
discs 192 for mating with magnetic surfaces 191 on the outlet
42.
[0150] While the invention has been described with regard to
mechanical adapters being a discrete and stand alone device, it
will be appreciated that the invention applies equally to the cases
wherein the adapter is an integral with the outlet, or to the cases
wherein the adapter is an integral with the module.
[0151] Home Network Based Module.
[0152] A general functional schematic block diagram of a module 250
typically used in home network environment is shown in FIG. 20. The
module 250 facilitates a data network over in-house wiring
simultaneously with the basic service, which the wiring was
originally installed to support. Non-limiting examples are a
telephone outlet connected to the telephone wiring to support
telephone service, a power outlet connected to the power wiring to
support AC power distribution and a CATV outlet connected to the
CATV cabling to support CATV distribution. The module connects to
the outlet via a connector 251. Since in most cases the module 250
is required to retain the basic service (being telephony, AC power
or CATV) added to data networking functionality, the module 250
embeds a service connector 253 used to provide the original
service. A data/service splitter/combiner 252 is used to separate
(and combine) the basic service signal carried over the wiring from
the data signal. For example, in the case wherein the data and the
service each use signals of a different frequency spectrum over the
wiring (FDM--Frequency Division Multiplexing), the
splitter/combiner 252 will use a first filter to isolate the
service signal spectrum and to couple it to service connector 253
as well as a second filter to isolate the data signal spectrum and
to feed it to a medium modem 254. Similarly, the service and data
signals are combined by the splitter/combiner 252 and fed to the
wiring via connector 251. In some implementations, the technology
enables a direct connection of the medium modem 254 and the service
connector 253, thus obviating the need for the data/service
splitter/combiner 252, and both the medium modem 254 and the
service connector 253 are directly connected to the wiring
connector 251. Medium modem 254 functions to transmit and receive
data over the wiring. In the case of a power outlet, the medium
modem 254 enables carrying data over the powerlines. Similarly, the
medium modem 254 enables carrying data over the telephone wiring in
the case of telephone outlet and over the CATV cables in the case
of CATV outlet. In most cases, the modem 254, working together with
the splitter/combiner 252, is optimized neither to interfere with
the basic service signal carried over the wiring nor to be
interfered by it.
[0153] The module 250 provides access to the data carried over the
in-house wiring via a module integrated interface, comprising data
connector 258 and interface adapter 256. Interface adapter 256
functions to include all circuitry required in order to support the
required interface when connected to the data network, while the
actual physical connection uses data connector 258, representing
data connector 34 described above. In general, any serial or
parallel data interface may be used. However, in most cases, the
data interface supported as well as the connector 258 will adhere
to a common standard data interface. Examples of such digital data
interfaces are IEEE802.3 10/100/1000BaseT (commonly using RJ-45
connector type 34 shown above), USB (Universal Serial Bus),
IEEE1284, EIA/TIA-232, IEEE1394 as well as others. Furthermore, the
interface supported by the module 250 through connector 258 may
also be of analog type rather than the digital type described. Some
examples describing outlet built-in interfaces are: [0154] 1.
Analog video interface. The outlet may be used to input analog
video, output analog video or both. It should be noted that this
video is to be distinguished from the CATV video signal carries as
basic service, but rather involves a video signal carried in
digital form as part of the data network formed. An outlet
supporting an analog video interface is described in WO 03/039150
entitled `Outlet with analog signal adapter, a method for use
thereof and a network using said outlet` assigned to the present
assignee. In such an outlet, the interface adapter 256 comprises
Analog to Digital (A/D) or Digital to Analog (D/A) converters as
appropriate. [0155] 2. Analog voice (audio) interface. The outlet
may be used to input analog voice, output analog voice or both. It
should be noted that this voice is to be distinguished from the
telephony signal carried as basic service, but rather involves a
voice signal carried in digital form as part of the data network
formed. In such an outlet, the interface adapter 256 comprises
Analog to Digital (A/D) or Digital to Analog (D/A) converters as
appropriate. [0156] 3. Telephone interface. The outlet may be used
to connect to a telephone device. It should be noted that this
telephone signal is to be distinguished from the telephone signal
carried as basic service, but rather involves a telephone signal
carried in digital form as part of the data network formed. An
outlet supporting telephone interface is described in WO 03/005691
entitled `Telephone outlet with packet telephony adapter, and a
network using same` assigned to the present assignee. In such an
outlet, the interface adapter 256 comprises Analog to Digital (A/D)
or Digital to Analog (D/A) converters as appropriate.
[0157] In the basic scenario, interface adapter 256 can be directly
connected to the medium modem 254, allowing signal flow from a unit
connected to the outlet via connector 258 and interface adapter 256
to the wiring via the wiring connector 251 through the medium modem
254 and the splitter/combiner 252. In such cases, hub 255 and
management 257 are not required.
[0158] In a managed data network environment, it would be
beneficial to include part or all of the network management
functionalities into the module 250. For example, addressing means
may be integrated into the outlet in order to allow the outlet to
be remotely referenced. In yet another example, QoS (Quality of
Service) tools are embedded into the outlet for measuring the
service. Outlet integrated network management functionalities may
comprise or support: [0159] 1. Performance management. Measure and
track network variables such as throughput, response time and line
utilization. [0160] 2. Configuration management. Monitor and change
configuration information to track the affects of software and
hardware elements. [0161] 3. Accounting management. Measure
utilization so that use of network resources can be tracked and
regulated. [0162] 4. Fault management. Detect, log and notify users
of problems relating to the network running effectively. [0163] 5.
Security management. Control access to network resources.
[0164] The network management functionalities are supported by the
optional management/processing unit 257. Management functionalities
may also include local--on outlet--visual indicators, such as
indicators 33a and 33b described above. The management/processing
unit 257 is coupled to all relevant functions in the outlet such as
medium modem 254, hub 255 and interface adapter 256.
[0165] An optional multi-port unit (hub) 255, identical to hub 11
described above, may be used in order to mediate the multiple data
streams in the outlet. Basically, the hub 255 mediates between the
data stream associated with the external data device connected via
connector 258 and interface adapter 256 and the network formed over
the wiring via medium modem 254.
[0166] A telephone module 260, representing for example module 30
above, is shown in FIG. 21 as a non-limiting example of module 250.
The module 260 is based on HomePNA technology known in the art for
carrying data over active telephone wiring. Connector 261,
associated with connector 251 of module 250, is used to connect to
the in-house telephone wiring. Such connector 261 represents the
connector 31 described above. Splitter/combiner 252 of general
module 250 are implemented by a set of Low Pass Filter (LPF) 262
and High Pass Filter (HPF) 265. Similarly, the medium modem 254 of
general module 250 is implemented by PNC (phonelines carrier) modem
264. Connector 263 is a standard telephone connector (e.g. RJ-11 in
North America) representing general service connector 253 of
general module 250. Such connector 263 represents the connector 32a
described above.
[0167] Similarly, an example of a powerline module 270,
representing for example module 100 above, is shown in FIG. 22. The
module comprises power connector 273 retaining the original AC
power device, wiring connector 271 to connect to the AC power
wiring via power outlet such as 102, and PLC modem 274. Such
connector 273 represents connector 101 described above. In this
example, no separation is required between the wiring, the PLC
modem 274 and the power connection 273, hence splitter/combiner 252
of the general module 250 is not required. Some PLC modem 274
implementations may still require such separation device.
[0168] Another example of the general module 250 is the CATV module
280, representing for example module 90 above, shown in FIG. 23.
Connector 281 provides the connection to the coaxial cable, and the
CATV service is retained via RF connector 283. Such connector 283
represents connector 91 described above. A coax modem 284 is used
as the medium modem. In most cases the data network uses one of the
video channels carried over the coaxial cable, the
splitter/combiner 252 is replaced by Band Pass Filter (BPF) 282,
and the connector 283 is directly connected to the wiring connector
281. Such connector 281 represents the connector 94 described
above.
[0169] LAN Environment.
[0170] While the invention has been described with regard to
networks formed over wiring used for utility services (e.g.
telephone, CATV and power), it will be appreciated that the
invention can be equally applied to outlets used in networks using
dedicated wiring. In such a scenario, the basic service is a single
data network interface. However, it may be required to provide
additional interfaces to an outlet, beyond the basic service of
single data connectivity interface. For example, it may be used to
provide multiple data interfaces wherein the wiring supports such
single data connection. An example for such an outlet is the
Network Jack.TM. product family manufactured by 3Com.TM. of
Santa-Clara, Calif., U.S.A. In addition, such outlets are described
in U.S. Pat. No. 6,108,331 to Thompson entitled `Single Medium
Wiring Scheme for Multiple Signal Distribution in Building and
Access Port Therefor` as well as U.S. Patent Application US
2003/0112965 Published Jun. 19, 2003 to McNamara et al. entitled
`Active Wall Outlet`.
[0171] A non-limiting functional block diagram of such a module 290
is shown in FIG. 24. While the general structure is similar to
general module 250, some adaptations are required to the specific
application. The data/service splitter/combiner 252 is not required
since only a single type of signal is carried over the wiring. A
simple transceiver 293 is used to transmit and receive signals over
the network wiring. Transceiver 293a is used to interface the
wiring via connector 291. The `basic service` of data port is
provided via data connector 292, using transceiver 293b. Both
transceivers, as well as adapter 256 (connected to interface
connector 258) all share the data via hub 255. The outlet may be
managed by management/processing function 257.
[0172] Other Functionalities.
[0173] While the invention has been described with regard to active
(power consuming) components (e.g. modem) used to provide access to
the data signal carried over the wiring, it will be appreciated
that the invention equally applies to a module using only passive
components for providing such coupling. An example of such
implementation is described with regard to a passive outlet is
disclosed in WO 02/25920 to Binder entitled `Telephone
communication system and method over local area network wiring`.
Such outlets are available as part of the etherSPLIT.TM. system
from QLynk Communication Inc. of College Station, Tex. USA.
[0174] While the invention has been described with regard to
digital interfaces, it will be appreciated that the invention
equally applies to a module wherein the adapter 256 converts to
analog signal interface, such as audio or video, as well as analog
sensor or analog actuator. Active outlets comprising a built-in
analog converter are described for example in WO 03/039150 to
Binder published May 8, 2003 and entitled `Outlet with Analog
Signal Adapter, a Method for Use Thereof and a Network Using Said
Outlet`. An illustration of an exemplary module 288 with video
interface is shown in FIG. 25, based on module 100 described above.
Data connector 34 comprised in module 100 of FIG. 10a is
substituted with video connector (F-Type, BNC or similar) 259 shown
in FIG. 25. The relevant adapter 256 will include analog to digital
(or digital to analog or both) functions. It should be noted that
connector 259 is part of the module 288 and relates to video (or
any analog signal) carried in digital form over the network, and
should be distinguished from connector 91 of module 90 of FIG. 9,
wherein the video is the basic service and thus carried in analog
form over the network
[0175] While the invention has been described with regard to wired
and connector-based module 288, it will be appreciated that the
invention equally applies to an outlet wherein a data unit uses
non-wired interface, such as audio, light (e.g. infrared) and radio
frequency (commonly referred to as wireless). Such outlet is
described in WO 01/80543 published Oct. 25, 2001 to Binder,
entitled `Network Combining Wired and Non-Wired Segments`. In such
a case, the connector 258 will be replaced substituted with a
non-wired transceiver, such as a light emitter/receiver or antenna
for RF. Alternatively, the non-wired interface is provided in
addition to the wired interface. A pictorial view of the latter is
module 268 with wireless interface is shown in FIG. 26, based on
module 145 shown in FIG. 14b above. In addition to the data
connector 34 in module 145 of FIG. 14b, an antenna 269 is shown in
FIG. 26, as an example to non-wired interface.
[0176] While the invention has been described with regard to
outlets having a single network interface (e.g. single connector
258), it will be appreciated that the invention equally applies to
the case wherein multiple network interfaces are supported.
Furthermore, a mix of interface types may be employed, such as
wired digital, wired analog and non-wired interfaces all in the
same outlet. Similarly, while the invention has been described with
regard to outlets having single basic service connection, such as
telephone connector 263, power connector 273, CATV connector 283 or
data network connector 292, it will be appreciated that the
invention equally applies to the case wherein multiple such
connections are provided.
[0177] While the invention has been described with regard to
outlets and networks based on conductive media such as wires and
cables, it will be appreciated that the invention equally applies
to the case wherein the network medium is non-conductive, such as
fiber-optical cabling. In such a case, transceiver 293a of module
290 should be substituted by a fiber optic transceiver, and
similarly wiring connector 291 should be replaced by a fiber optic
connector. Active outlets supporting data interfaces and based on
fiber optic cabling are described in U.S. Patent Application US
2002/0146207 published Oct. 10, 2002 to Chu, entitled `Fiber
Converter Faceplate Outlet`, as well as in U.S. Pat. No. 6,108,331
to Thompson entitled `Single Medium Wiring Scheme for Multiple
Signal Distribution in Building and Access Port Therefor`. As such,
the term `wiring` in this application should be interpreted to
include networks based on non-conductive medium such as
fiber-optics cabling.
[0178] Module Powering.
[0179] In one or more of the embodiments according to the present
invention, the module includes active components (such as medium
modem 254), and as such needs to be powered. Three non-limiting
powering schemes are now described including local feeding, power
over wiring and via the interface module.
[0180] Local Feeding.
[0181] In this implementation the module is connected to an
external power source for feeding its active components. A
pictorial view of such an approach is shown in FIG. 27,
illustrating a module 279 according to any of the above
embodiments. A common small AC/DC converter 278 is used
(connectable to power socket 93 in distinct power outlet 102),
connected to the module via plug 296.
[0182] A power adapter may be used in the module, for adapting the
external power to the internal needs. Such adapter may include
voltage conversion (such as DC to DC converter) in order to adapt
to specific voltages required, protection circuits (such as fuse or
current limiting), regulation and noise filtration, as well as
other functionality as known in the art. In addition, such an
adapter may comprise the functionality of an external AC/DC
converter 278, allowing the module to be directly connected to the
mains obviating the need for external converter 278. Schematic
block diagram of such a module 295, comprising such power adapter
function 297 is shown schematically in FIG. 28. The power adapter
is fed from an external source via connector 296, and outputs the
required DC power to all power-fed components in the module.
[0183] Power Over Wiring.
[0184] In one or more embodiments according to the present
invention, the module is fed by power carried over the wiring and
via the outlet to which the module is connected. The power may be
carried over separated conductors. In this case, the same wiring
connector 251 may be used to connect to the power carrying
conductors using separated pins. Alternatively, additional power
dedicated connector may be used.
[0185] In one or more preferred embodiments, the power is carried
simultaneously over the wiring carrying the data network signals
and/or the basic service signal. Such a module 285 is shown
schematically in FIG. 29. The power splitter function 287 serves to
extract the power carried over the wiring, and feed it to the power
adapter 286, rather than the adapter 297 being externally fed. In
most cases, the power splitter 287 operation should not interfere
with the data and basic service also carried over the same wiring
(e.g. loading effects and impedance matching).
[0186] The implementation of such a mechanism is trivial wherein
the basic service is AC power as described above with respect to
module 270 shown in FIG. 22. The power splitter 287 comprises a
simple filter and the power adapter 286 comprises a standard AC/DC
converter (similar to the external unit 278 described above).
[0187] Recent techniques developed allow for carrying
simultaneously power and basic service (and data) over the same
wiring infrastructure. U.S. patent publication 20020003873 to
Rabenko et al. entitled: `System and method for providing power
over a home phone line network` teaches carrying AC power over
telephone wiring carrying both telephony and data, by using a part
of the spectrum not used by the other signals. Similarly, a recent
technique known as Power over Ethernet (PoE) (a.k.a. Power over
LAN) and standardized under IEEE802.3af, also explained in U.S.
Pat. No. 6,473,609 to Lehr et al. entitled `Structure Cabling
System`, describes a method to carry power over LAN wiring, using
the phantom mechanism. The above technologies, as well as others,
may be used to provide power to any of the modules described above.
The power splitter 287 is adapted in accordance with the way power
is carried. For example, in the case of using different spectrum
for the power signal, a filter should be used. In the case of
phantom type of feeding, two transformers are required as known in
the art.
[0188] Powering Via Connected Appliance.
[0189] As explained above, several data interface standards also
carry power over the interface. For example, in the case where the
module is connected to USB host unit, the USB interface may feed
the module.
[0190] While the invention has been described with regard to a
single power source, it will be appreciated that the invention
equally applies to the case wherein multiple power sources are used
either for redundancy or load sharing.
[0191] Non-Networking Functionalities.
[0192] While the invention has been described with regard to adding
networking related functionality to an existing outlet, it will be
appreciated that the invention equally applies to any other
functionality to be added to an existing outlet by mechanically
attaching and electrically connecting thereto. In one or more
embodiments, the added functionality involves functions commonly
offered as part of outlets.
[0193] One example may be added connections. Some outlets provide a
single jack, while others provide multiple connections. A module
according to the present invention may provide additional
connections to a single-connection existing outlet.
[0194] Such non-networking related functionalities may be provided
alone, or added to the above networking related functionalities. In
the latter case, a module comprises both functionalities into a
single enclosure.
[0195] AC Power Module.
[0196] An exemplary module 300 according to the invention is shown
in FIG. 30a, connectable to a power outlet 102 comprising single
power socket 93. The module 300 is mechanically attached to the
outlet 93 using side clamping elements 71 as described above, and
provides three power sockets 101a, 101b and 101c, each electrically
connected directly to the socket 93. It will be appreciated that
any other number of sockets may also be provided. Furthermore, the
module may be used to convert from one type of socket to another
(such as from US type to European type). In the latter case, the
module may comprise the transformer required for voltage adaptation
(e.g. from 110 VAC to 240 VAC).
[0197] Some power outlets are available offering built-in switched
power sockets. Other outlets are known to comprise a built-in
dimmer for lighting applications. Similarly, such functionalities
may be added to an existing outlet by means of a module according
to the present invention. Module 301 shown in FIG. 30b provides
switch 304, connected in series to socket 302 to switch its power.
Additionally, dimmer button 305 is shown, controlling in-module
dimmer circuitry, to work in conjunction with socket 303. It will
be appreciated that, if desired, only one of the additional
functionalities (i.e. switching and dimming) need be provided.
Likewise, more than two additional functionalities may be provided
where space permits.
[0198] Other non-limiting examples of functionalities which may be
available in power outlets and may be embedded in modules in order
to allow adding such functionalities to existing outlets (in
addition to switching and dimming) are: [0199] Fuses, and other
safety means. [0200] Lightning protection, and any other protection
means for protecting the connected appliance. [0201] Visual
indicators. [0202] Grounding means such as side wiring. [0203] Fan
speed control. [0204] TEST and RESET buttons for testing and
resetting fuses. [0205] Electronic timer switching. [0206] Sensors,
such as infrared occupancy sensors. [0207] Filters (e.g. for noise
filtering). [0208] Security related sensors (e.g. heat, flood).
[0209] Telephone Module.
[0210] An exemplary module 310 according to the invention is shown
in FIG. 31, connectable to a telephone outlet 42 comprising single
telephone jack 43. The module 310 is mechanically attached to the
outlet 93 using any of the described above methods, and provides
four telephone jacks 311a, 311b, 311c and 311d. Each such jack may
be connected directly to the jack 43, allowing four telephone
devices to be connected to the same telephone line. Alternatively,
in the case wherein jack 43 supports two or more telephone
connections (using different pins), the telephone jacks 311 may
connect to different telephone lines (e.g. jacks 311a and 311b to
line 1 and jacks 311c and 311d to line 2). Such a module is
described in U.S. Pat. No. 6,366,671 to Beavers, entitled `Multiple
outlet telephone jack`.
[0211] Some telephone outlets are available offering built-in
micro-filters, known in the art for use in conjunction with ADSL
and HomePNA. Similarly, such micro-filters may be added to an
existing outlet by means of a module according to the present
invention. Other non-limiting examples of functionalities which may
be available in telephone outlets and may be embedded in modules in
order to allow adding such functionalities to existing outlets (in
addition to switching and dimming) are: [0212] Lightning
protection, and any other protection means for protecting the
connected telephone device. [0213] Visual indicators. [0214]
Sensors, such as infrared occupancy sensors. [0215] Fuses, and
other safety means. [0216] Filters (e.g. for noise filtering).
[0217] While the non-networking functionalities have been exampled
above with regard to power and telephone outlets, it will be
appreciated that the invention equally applies to any type of
outlet, including LAN and CATV outlets. In the latter case, a RF
splitter may be used within a module for providing multiple CATV
connections.
[0218] Integrated Appliances.
[0219] While the invention has been described with regard to adding
available outlet functionality to an existing outlet, it will be
appreciated that the invention equally applies to any other
functionality to be added to an existing outlet by mechanically
attaching and electrically coupling thereto. In particular, the
functionality of a device or an appliance which is commonly
connected to an outlet can now be integrated, in part or in full,
into the module. In such configuration, the need to connect via
cables the appliances to the outlet is obviated. In addition to the
improved aesthetics, excess exposed cables are inconvenient and
dangerous. A few integration examples are described herein.
[0220] Small AC/DC converters such as device 278 described above
are known as means to connect appliances to AC power. Such
converter 278 may be directly attached to a power outlet or
connected thereto via a power cord. In one or more embodiments of
the invention, such a converter 278 is integrated into a module.
The converter may be integrated as a sole functionality of the
module or added to other functionalities. The latter is
demonstrated by a module 321 illustrated in FIG. 32a, based on
module 301 described above. In addition to switching and dimming
functions, the module 321 further comprises a converter 278,
allowing devices to be connected thereto by DC connector 322. Such
an outlet with built in AC/DC converter is described in Canadian
Patent Application 2,420,515 to Eckel et al. entitled `Cordless
telephone outlet device`.
[0221] Power module 323 attached to a power outlet 102 is shown in
FIG. 32b. Similar to outlet 100 described above, module 323
provides three data connections 34a, 34b and 34c. The module 323
further includes a power switch 304 as described above with regards
to module 321, and may include a switch 304 controlled power socket
302. In another embodiment, the module 323 provides a night light
function integrating a switch 304 controlled lamp house 324 and
lamp 325 connected thereto. Add-on night light devices are known as
add-on stand alone housings. As shown in FIG. 32b, the full night
light functionality, including a switch, lamp and lamp house, are
fully integrated into the module 323. While the lamp housing 324 is
shown in FIG. 32b as rigidly attached to the module, flexible
mechanical attachment may also be used, as shown with regards to
the exemplary module 327 shown in FIG. 32c. In this configuration,
the lamp house 324 is attached to the module body be means of
flexible holder 326. A power outlet with built in lighting function
is disclosed in U.S. Pat. No. 5,473,517 to Blackman, entitled
`Emergency Safety Light`.
[0222] Another example of a device connected to a power outlet is a
charger, such as PDA (Personal Digital Assistant) or cellular phone
chargers. Such chargers commonly comprise a charging circuit and a
mechanical base for the charged device. In one or more embodiments
according to the present invention, such charger functionality is
integrated into the module. A front view of such a module 330,
based on module 100 described above, is shown in FIG. 33a, and a
rear view is shown in FIG. 33b. Added to the functions of module
100, module 330 comprises PDA charger functionality. In addition to
the built-in charger the module 330 further comprises a receptacle
331 and connector 339, for providing electrical connectivity and
mechanical seating to the charged PDA. The module 330 connects
electrically to an AC power outlet via the two prongs forming the
AC plug 332, and is attached thereto by any of the described above
methods. A PDA 333 in a charged position (assuming the module 330
is attached to an AC power outlet) is shown in FIG. 33c. While
described above with regard to PDAs, it will be appreciated that
any mobile device may substitute the PDA, such as receptacle 336
and cellular telephone 337 shown in conjunction with the respective
module 335 in FIG. 33d.
[0223] While modules 330 and 335 above are described as supporting
only power functionalities, it will be appreciated that data
networking may also be added. For example, in the case wherein the
AC power wiring also carries data signals (as described above),
powered (or charged) devices (such as PDA 333 or cellular telephone
337) may also access this data network signal, acting as active
nodes in the network. In such case, the module comprises part or
all of the data functionality described above.
[0224] While modules 321, 330 and 335 are described above with
regard to power modules providing power to devices/appliances
connected/attached thereto, it will be appreciated that such power
feeding functionalities may be included in other outlets (e.g.
telephone, CATV and LAN outlets). The module may be powered by any
one of the described above module powering methods (or combination
thereof). One such exemplary telephone module 338, based on
telephone outlet 279 described above, is shown in FIG. 33e. The
module 338 is locally fed for powering its circuits, as well as
charging the PDA 333 via a mechanical receptacle 331.
[0225] While the modules are described above primarily for
supporting power functionalities, it will be appreciated that data
networking may be the primary or sole functionality supported. In
such case, the device connected (e.g. PDA 333 or cellular phone
337) is coupled to the data signal carried over the wiring, acting
as a node in the data network. The module comprises part or all of
the data functionality described above, but in addition (or
instead) to the data connector (e.g. connector 34) connects to the
respective device. Furthermore, in addition to the example of PDA
333 and cellular telephone 337, it will be appreciated that any
other device may be supported for powering, data or both.
Non-limiting examples are handheld or mobile devices such as
digital camera, digital music player, digital video player and web
pads.
[0226] While the modules 330, 335 and 338 are described above as
providing a docking function for holding either a PDA 333 or a
cellular phone 337, it will be appreciated that any other such
mechanical base, docking unit or mechanical attachment means may be
used. In the general case, the module according to one or more
embodiments according to the present invention provides a
mechanical means (e.g. receptacle 331) for mechanically attaching
devices thereto (e.g. PDA 333 and cellular phone 337). The
mechanical attachment may use gravity to hold the appliance to the
module, or alternatively use (solely or in addition to gravity) a
latching mechanism to secure such attachment. Such mechanical means
(to be distinguished from the mechanical means used for attaching
the module to the outlet) may also support electrical connection
(as shown for the base 331 above, also providing power connection).
In other embodiments, the electrical connection uses a connector
provided by the module. A clear advantage of such approach is the
ability to hang appliances and devices on the wall, rather than
occupying a commonly loaded desk space.
[0227] It should be noted that U.S. Pat. No. 6,518,724 to Janik
entitled `Wall switch device and power outlet device` discloses a
power wall switch comprising a cradle for PDA or cellular
telephone, as well as built-in wireless functionality. However, the
cradle functionality described by Janik is part of the outlet and
is not provided as an add-on module. Furthermore, Janik describes
only a power outlet and in particular a wall switch, and is silent
about other types of outlets such as telephone, CATV and LAN
outlets.
[0228] Integrated Telephone Appliances.
[0229] While the invention has been described with regard to
integrating power consuming devices to a power module, it will be
appreciated that the invention equally applies to integrating
telephone-outlet connected devices to telephone modules. Examples
of such devices or appliances which commonly connects to a
telephone outlets are: [0230] Answering machines. [0231] XDSL
modem, including ADSL modem. [0232] Dial-up modem. [0233] Telephone
set. [0234] Cordless telephone, such as cordless telephone base
unit. [0235] Telemarketing avoiding devices. [0236] Caller-ID
units.
[0237] Any one or more of the above functionalities may be
integrated into an outlet. Furthermore, the outlet may provide
mechanical means for attaching any of the devices thereto.
[0238] Integrated CATV Appliances.
[0239] While the invention has been described with regard to
integrating power or telephone consuming devices to respective
power or telephone modules, it will be appreciated that the
invention equally applies to integrating CATV-outlet connected
devices to CATV modules. Examples of such devices or appliances
which commonly connects to a CATV outlets are: [0240] Cable modem
(e.g. DOCSIS based) [0241] Set Top Box. [0242] VCR. [0243] DVD.
[0244] Television sets. [0245] DVR (Digital video recorder). [0246]

[0247] Non-Technical Applications.
[0248] While the modules above are described with regard to
technical functionalities, it will be appreciated that the
invention may be implemented for non-technical applications such as
improved aesthetics. In such applications, the module may be
limited to the provision of a decorative design and not necessarily
include electrical or mechanical functionality. Such a design may
be suited to the householder's taste, and may for example be used
to harmonize with other parts of the room. For example, a module
according to the present invention may have a unique color, texture
or decoration. Most available outlet faceplates are offered in a
very limited number of colors and shapes, and such a module allows
for a specific color, shape, texture, decoration or any other
ornamental feature. Furthermore, in the case wherein there is a
need to change the color, for example in the case of painting the
walls, such change can be easily done with the module, obviating
the need to replace part or all the existing outlet and obviating
the need to interfere with the utility wiring.
[0249] In addition to decoration (e.g. color), the module may be
shaped in an artistic manner. Examples of module shapes, structures
and other ornamental designs are shown in FIGS. 34a and 34b. Both
figures illustrate power modules based on power module 100
described above, with the distinction of providing two data
communication ports 34a and 34b, rather than the single data
connector 34 comprised in power module 100. A power module 341 is
shown in FIG. 34a attached to a power outlet 102, and providing a
power socket 101 and a visual indicator 33a. The module 341 is
shaped as a `teddy-bear` face. Such structure, as well as any other
animal theme shapes may fit into a child's room. Other themes may
also be employed, such as a sports personality or musician, musical
instrument and so on. Another artistic aspect is shown as oval
shaped power module 342 in FIG. 34b. The module 342 is shown as
using snap locking attachment method based on tabs 111a (not shown)
and 111b as described above.
[0250] Status Indicators.
[0251] The module may comprise visual indicators 33a and 33b as
described above for allowing the user to easily observe the module
status. Such indicators may be LEDs (Light Emitting Diode) known in
the art. The visual indicators may be used to indicate the
following module status.
[0252] Power.
[0253] The visual indicator may be used to indicate the existence
of power in the module to power its internal active circuits.
Various techniques have been described above for powering a module.
Regardless of the power source to the module (as described above),
such indication will ensure that indeed power reaches the module.
Such indication is commonly marked as `POWER` or `ON`. The
indicator can be coupled directly to the power signal feeding the
module or alternatively coupled to the power supply output. In the
latter case, the indicator is used to indicate both the power
signal availability and the proper operation of the internal power
supply. The latter case is demonstrated in FIG. 35. The module 350
shown is based on module 285 described above. The module 350
comprises a LED 352 connected in series to a resistor 351, required
for current limiting. The LED 352 may serve in this configuration
as indicator 33a, for example. The LED 352 is connected to the
output of power adapter 286, hence the illumination of LED 352
indicates the proper operation of both the power adapter 286 and
the power splitter 287, as well as the existence of power feeding
to the module 350.
[0254] Proper Operation.
[0255] A visual indicator may also be used to indicate the proper
operation of part or all of the electronic circuits integrated
within the module. The electronic circuits within the module may
support self-test or any other built-in diagnostics means, wherein
the test results will be signaled by a visual indicator.
[0256] Communication Status.
[0257] In the case wherein the module comprises communication
functionality, the module may indicate the availability and the
status of the communication. In general, two communication links
may be involved. One communication link refers to the availability
of a data communication signal over the service wiring so as to
indicate that modem 254 receives a valid communication signal. For
example, in the case wherein two modules are installed in a home to
allow communication between them, both will indicate the existence
of a network over the service wiring. The other communication link
involves the communication between a data unit connected to the
module and the module. Such communication link may be established
upon connecting an appropriate operative data unit to connector 258
(or 34) of the module. Such status indication can be based on a
`Link Pulse` mechanism commonly used in Ethernet IEEE802.3
10/100BaseT based networks.
[0258] In addition to indicating the existence of operative data
network, it is useful to have information about the performance of
such a communication link. For example, the data rate (either
effective or nominal) may be an important network parameter. In
this case, the visual indicator will provide information about the
network performance. Common 10/100BaseT Ethernet networks commonly
employs two indicators to signal if the system works in the 10 Mb/s
or 100 Mb/s modes. Any other visual indicators providing quantified
information may be used, such as `bar graph`, number, multiple
intensity levels and the like.
[0259] Service Monitoring.
[0260] The module may comprise a service monitoring means. In such
a case, the visual indicator signals the availability and the
status of a service signal. In the case of power module, the
availability of AC power (either 110 or 220 VAC) will be sensed and
indicated. In the case or telephone module, the indicator may
reflect the existing or a telephone signal, the existing of `OFF
HOOK` state, ringing state and the like. Similarly, in the case of
CATV module, the existence of the CATV signal may be indicated
[0261] The above various states may be each represented by a single
dedicated single-state indicator. However, in order to reduce
complexity, known techniques are commonly used in order to combine
signals. Such techniques may use different colors (of the same
indicator), different intensity levels, variable duty-cycle and so
forth. While visual indicators have been described, other
indicating methods may be used such as audible tones (as stand
alone or combined with visual).
[0262] General.
[0263] While the invention has been described with regard to the
configuration wherein the existing outlet is a simple passive
wiring-only device and the added functionality resides in full in
the module, it will be appreciated that the invention equally
applies to other embodiments wherein the added functionality is
split between the outlet and the module.
[0264] While the invention has been described with regard to

the adapter, each comprising part of the required components.
Furthermore, in some configurations more than one module may be
required. In such a case, the modules can be stacked or organized
in various configurations, wherein each module may be mechanical
and electrically attached either to the outlet or to other module
or both. Any combination of an outlet and add-on module may be
considered as a new outlet, into which new module may be added
according to any embodiment of the present invention.
[0267] While the invention has been described with regard to
existing outlets, it will be appreciated that the invention equally
applies to the cases wherein the outlet is also upgraded, such as
substituting the outlet with a new one having part or all of the
improved features.
