utilized by the portable electronic device 100. FIG. 1B illustrates
a front surface 112 of the portable electronic device 100 having
the display 104 and the user input region 106. FIG. 1C illustrates
a back surface 114 of the portable electronic device 100. The back
surface 114 typically offers no user input or user output
capabilities.
[0004] Typically, the surfaces of portable electronic devices are
relatively easily damaged such as by scratches, dents and the like.
Covers, skins or cases have been conventionally utilized to provide
protection for the exterior surfaces of portable electronic
devices. Accordingly, users can protect their portable electronic
devices by placing covers or skins around their portable electronic
devices.
[0005] Additionally, accessories have been utilized to provide
additional functionality to portable electronic devices. Typically,
accessories are small electrical products that can attach who a
portable electronic device, such as through the external connection
port 108. One example of an accessory is a FM receiver provided as
a small electrical product that can be attached to a portable
electronic device via a cable, which is useful when the portable
electronic device does not already include a FM receiver. Another
example of an accessory is a wireless data capture device.

DETAILED DESCRIPTION OF THE INVENTION
[0041] The invention pertains to a cover for a portable electronic
device. The cover can include at least one electrical component.
For example, in one embodiment, an electrical component can be
embedded in the cover. When the cover is placed on or mated with
the portable electronic device, the electrical component embedded
in the cover is able to interact with electrical circuitry of the
portable electronic device. Advantageously, the cover can not only
provide a protective and/or ornamental covering for the portable
electronic device but can also augment the electrical capabilities
of the portable electronic device. The invention is particularly
well suited for portable, battery-powered electronic devices, and
more particularly handheld battery-powered electronic devices.
Examples of portable, battery-powered electronic devices can
include laptops, tablet computers, media players, phones, GPS
units, remote controls, personal digital assistant (PDAs), and the
like.
[0042] A cover for a portable electronic device can be made from a
variety of materials. In one particular embodiment, the cover can
be formed from a flexible and/or compliant material that is fitted,
i.e., conforms to, the contour of the portable electronic device.
For example, in one implementation, the cover is a flexible film
(e.g., a label) that attaches to a surface of the portable
electronic device. In another example, the cover can be a compliant
enclosure formed from materials, such as rubber or silicone, that
wrap and stretch around the surfaces of the portable electronic
device. The cover can also be referred to as a skin.
[0043] Embodiments of the invention are discussed below with
reference to FIGS. 2A-18. However, those skilled in the art will
readily appreciate that the detailed description given herein with
respect to these figures is for explanatory purposes as the
invention extends beyond these limited embodiments.
[0044] FIG. 2 is a simplified diagram of an electronic cover 200
for a portable electronic device, in accordance with an embodiment
of the present invention. The electronic cover 200 may be an outer
covering with integrated electronics that can be physically and
operatively coupled to a portable electronic device.
[0045] The electronic cover 200 may be configured to cover a
portion of one or more external surfaces of the portable electronic
device for ornamental and/or protective purposes. Additionally, the
electronic cover 200 can be configured at act as an electronic
accessory to the portable electronic device 200, i.e., a
supplementary system that improves the functional capabilities of
the portable electronic device. In most cases, the electronic cover
200 is a distinct element, which is not part of the originally
designed portable electronic device. Instead, the electronic cover
200 is an add-on or an accoutrement of the portable electronic
device. The electronic cover 200 may be configured to help protect
the portable electronic device (i.e., it may serve as armor or
shock protection that helps prevent structural and/or surface
damage to the portable electronic device). Additionally or
alternatively, the electronic cover 200 may provide ornamentation
to the portable electronic device (i.e., it may help define the
overall ornamental appearance of the electronic device). The
electronic cover 200 can also permit personalized ornamentation.
The electronic cover 200 may also provide tactility in order to
improve the feel and grip to the portable electronic device.
[0046] The electronic cover 200 can at least partially conforms to
the outer shape of the portable electronic device. For example, by
providing an internal shape/inner surface and/or being flexible
enough to follow the contour of the portable electronic device. The
external shape of the outer covering may be widely varied. It may
be designed for ornamental, protection, and/or ergonomic reasons.
Generally however, it tends to follow the general shape of the
portable electronic device.
[0047] The electronic cover 200 may for example be laid, set,
wrapped, spread upon, about or over a portion of the portable
electronic device. The electronic cover 200 may be configured to
cover a surface of the portable electronic device including a
portion of a single side, multiple sides, and/or all sides of the
portable electronic device. For example, the electronic cover 200
may be a film that is applied to a single surface of the portable
electronic device (e.g., a portion or all of the front surface).
The electronic cover 200 may also be a flexible covering that
includes a cavity for receiving the portable electronic device and
that wraps/stretches around some portion of the portable electronic
device. The outer covering may be referred to (among others) as a
case, shield, container, jacket, vest, skin, protector, and the
like of the portable electronic device.
[0048] The electronic cover 200 generally includes a body or member
202 that couples to the portable electronic device. The body or
member 202 may also decouple from the portable electronic device
such that it is a considered a removable or detachable. The body or
member 202 can be carried by the portable electronic device, but is
not part of the portable electronic device. The configuration of
the body or member 202 may be widely varied, but is typically
configured to cover the outer surface(s) of the portable electronic
device. The body or member 202 may be universal in its application
(not specific to a particular device) or it may be dedicated to a
particular device. In either case, the body or member 202 can be
configured to follow the outer contour or shape of the surfaces of
the portable electronic device. In one embodiment, the body or
member 202 forms a surface layer that attaches to the outer surface
of the portable electronic device. In another embodiment, the body
or member forms an enclosure that includes surfaces (e.g., walls)
that surround the outer surfaces of the portable electronic device.
For example, the surfaces may define a cavity for placement of the
portable electronic device. The body or member 202 may include
access openings and tactile features that are associated with
mechanisms of the portable electronic device. The tactile features
may also be associated with mechanisms of the covering. Even though
the general shape of the body or member 202 may be similar to the
portable electronic device, the external surface of the body or
member 202 may include one or more or any combination of patterns,
recesses, protrusions, ridges, depressions, dimples, flaps,
extensions, textures, knurls, and/or the like.
[0049] The electronic cover 200 can be formed from a variety of
materials including, for example, but not limited to soft, hard,
rigid, flexible, compliant, etc. Some examples of material types
include but are not limited to paper, plastic, metal, rubber,
silicon, fabric, foams, leather, ceramics, films, and the like. The
material generally depends on the desired needs of the outer
covering. It should be appreciated that the outer covering is not
limited to a single material and may include a combination of
materials. The exact combination may depend on the needs of the
outer covering. Examples of trade-offs include rigid/flexible,
soft/hard, soft1/soft2, plastic/metal, silicon/plastic, etc. In one
particular embodiment, the outer covering is formed from flexible
and/or compliant materials such as rubber, silicone, fabrics (e.g.,
neoprene), and various films.
[0050] The electronic cover 200 can be adhered to or around the
portable electronic device using a variety of techniques including
but not limited to: adhesive, friction, static, elasticity,
suction, fasteners, snaps, connectors, and the like. In some
examples, the electronic cover 200 forms an enclosure that includes
a void, cavity, opening, pocket or compartment for receiving a
portable electronic device therein (i.e., the portable electronic
device can be placed into the void). In another example, the
electronic cover 200 can be press fit onto the portable electronic
device. In yet other examples, the electronic cover 200 is a
surface (e.g., platform, film) that is attached to a surface of the
portable electronic device (e.g., adhesive backed surface or
surface with static electricity properties or a surface with
suction cups). In yet other examples, the electronic cover 200 is
stretched around the portable electronic device (e.g., the outer
covering is flexible and conforms to the outer shape of the
portable electronic device). In other examples, the electronic
cover 200 can trap or surround the portable electronic device
between multiple sections (i.e., lower and upper half).
[0051] In accordance with one embodiment, the electronic cover 200
may be formed from a soft, flexible and/or compliant material that
can be wrapped around the various surfaces of the portable
electronic device. For example, the material may allow the covering
to stretch over the portable electronic device (e.g., form
fitting). By way of example, the electronic cover 200 may be formed
from a stretchable material that includes a small opening that can
be stretched to accommodate the larger portable electronic device
as it is inserted into the electronic cover 200 outer covering.
Once the portable electronic device is inserted, the material
confirms to the shape of the portable electronic device, which
provides a tight fit around the surfaces of the portable electronic
device. The electronic cover 200 may, for example, surround
multiple side surfaces if not all of the side surfaces of the
portable electronic device. In one particular example, the material
may be silicon. These types of coverings are sometimes referred to
as "skins" as they create a new outer layer analogous to skin.
[0052] The electronic cover 200 may include a variety of access
openings 203 depending on the configuration of the portable
electronic device. The access openings 203 provide access to
features of the portable electronic device. The access openings
may, for example, provide openings for one or more displays,
buttons, switches, navigation pads, keys, touch pads, receivers,
microphones, speakers, connectors, jacks, sensors, antennas,
cameras and the like. The electronic cover 200 may also include an
access opening for helping place the outer covering relative to the
portable electronic device as for example in situations where the
outer cover surrounds a majority of the sides of the portable
electronic device.
[0053] In accordance with one embodiment, the electronic cover 200
can be configured to include electronic circuitry 204. The
electronic circuitry 204 can include one or more electronic
components, such as one or more electronic subassemblies, for
connection to the portable electronic device. The one or more
electronic subassemblies may interface with the portable electronic
device via an existing connector of the portable electronic device,
via a special connector dedicated to the outer covering or via a
wireless connection. The one or more electronic subassemblies can
be embedded (partially or entirely) within the walls of the
electronic cover 200 and/or the electronic subassemblies can be
carried by the electronic cover 200 as for example on an exterior
or interior surface. The electronic subassemblies may be used to
provide additional functionality to the portable electronic device
and/or to extend functionalities of the portable electronic device
to the electronic cover 200.
[0054] Advantageously, the cover or outer covering according to
various embodiments can provide a paradigm shift for electronic
device covers, which have conventionally been provided for
protection of outer physical surfaces of portable electronic
devices. Now, the cover or outer covering can operate as an
electrical accessory for the portable electronic device. Here, the
cover or outer covering includes active elements that can interact
with active element of a portable electronic device. The cover or
outer covering having active elements can be considered a smart
cover or active cover. In order to be smart and/or active, the
smart or active outer cover generally includes one or more
electrical components that are carried by the body or member 202 of
the electronic cover 200. In some cases, the components can be
discrete separate components that are spaced apart from one another
while still maintaining communications there between (e.g., wires,
traces, flexes). In other cases, at least a portion of the
components can be grouped together onto a single carrier such as a
printed circuit board, flex circuit, rigid flex, subassembly or
electronic enclosure. These components may be embedded and/or
surface mounted. Several of the components will be described in
detail below.
[0055] In one embodiment, the electronic cover 200 can include a
connection terminal 205 for operatively connecting to the portable
electronic device. The connection terminal 205 may serve as a data
and/or power connection. In wired connections, the connection
terminals are configured to physically connect so as to operatively
couple the electronic cover 200 to the portable electronic device.
For example, the interface may include a mating connection made up
of corresponding mating connectors. The connector may be dedicated
to the interface between covering and device. The connector may
also be associated with an existing connector of the device. For
example, if the device includes a female port then the covering may
include a male protrusion that engages the female port. In order to
allow further connection to the device when the covering is on the
device, the connector of the covering may include a second
connector, which in one implementation can mimic the connector of
the device. In one embodiment, the first and second connectors are
integrated into a single connector unit. For example, the covering
may include a female/male connector. In another embodiment, the
first and second connectors are separated in space but electrically
coupled together as for example through the use of conductive
traces, flex circuits or wires.
[0056] The configuration of the contacts of the connector and the
signals they carry may be widely varied. For example, the spacing,
numbers of pins and layout of pins (rows/columns) and the like of
the connector may be varied. Furthermore, the contacts may be used
for data, ground, charging, protocols, accessory identifier, audio,
line in, line out, video, sensors, etc. By way of example, the
connection interface may be associated with one or more of the
following interfaces: PS/2, serial, parallel, network (e.g.,
Ethernet), USB, Firewire and/or the like. The connection interface
may also include one or more remote, audio (digital or analog),
video (digital or analog), and/or charging interfaces. In one
example, the connection interface corresponds to a thirty (30) pin
connector utilized in devices manufactured by Apple Inc. of
Cupertino Calif.
[0057] In wireless connections, the terminals do not physically
connect. For example, the interface may include a receiver and
transmitter (transceiver) for wireless communications there
between. By way of example, the connection interface may include
one or more of the following interfaces: Bluetooth, WiFi, 802.11,
optical (e.g., infrared, magnetic link (induction) and/or the
like.
[0058] The electronic cover 200 can include a controller 208 (e.g.,
processor or CPU) configured to execute instructions and to carry
out operations associated with either the electronic cover 200 or a
portable electronic device coupled thereto. For example, using
instructions retrieved, for example, from memory, the controller
may control the reception and manipulation of input and output data
between components of the electronic cover 200 as well as
components of a portable electronic device coupled thereto. The
controller may act alone or work with the controller of the
portable electronic device depending on the needs of the
system.
[0059] The controller 208 can be implemented on a single chip,
multiple chips or multiple electrical components. For example,
various architectures can be used for the controller, including
dedicated or embedded processor, single purpose processor,
controller, ASIC, etc. By way of example, the controller may
include microprocessors, DSP, A/D converters, D/A converters,
compression, decompression, etc. In most cases, the controller
together with program code (e.g., firmware, software), such as an
operating system, can operate to produce and use various data. The
operating system may correspond to well known operating systems
such as OS/2, DOS, Unix, Linux, and Palm OS, or alternatively to
special purpose operating system, such as those used for limited
purpose appliance-type devices. The program code and data may
reside in a data storage device (e.g., memory) within the outer
covering and/or the portable electronic device coupled thereto. The
data storage device may include read-only memory (ROM),
random-access memory (RAM), flash memory, etc. These components can
be implemented on a single chip, multiple chips or multiple
electrical components. The data storage device can alternatively or
additionally include a hard disk drive such as a micro drive and/or
removable storage device such as mini DVD drives or a card slot for
receiving mediums such as memory cards (or memory sticks).
[0060] The electronic cover 200 can also include various input
devices 210. These one or more input devices can be connected with
the portable electronic device, such as through the connection
interface. The one or more input devices can be configured to
transfer data from the outside world into the outer covering and/or
a portable electronic device coupled thereto. The one or more input
devices may correspond to data entry mechanisms or data capture
mechanisms. The input devices may include touch sensing devices,
such as touch screens, touch pads and touch sensing surfaces, or
mechanical actuators, such as button, switches, keys or wheels.
[0061] The electronic cover 200 can also include one or more data
capture mechanisms or sensors 212 that can be operatively connected
with the portable electronic device, such as through the connection
interface. The one or more data capture mechanisms or sensors 212
may, for example, include motion sensing devices such as
accelerometers, force sensors, image sensors, microphones,
biometric sensors, temperature sensors, light sensors, proximity
sensors, and/or the like.
[0062] The electronic cover 200 can also include one or more output
devices 214 that can be operatively connected to the portable
electronic device, such as through the connection interface. The
output devices 214 of the electronic cover 200 can be configured to
receive data from the portable electronic device. The output
devices may include one or more of: displays (such as an LCD),
speakers or jacks, audio/tactile feedback devices, light
indicators, and the like.
[0063] The electronic cover 200 can also include a power module
216. The power module may include a battery. The electronic cover
200 may also include an on-board charging system. The charging
system may include an inductance charging means and/or a solar
charging means (e.g., photovoltaics) and/or a kinetic charging
means. For example, the outer covering may include an inductive
surface that mates with a corresponding external inductive surface
in order to charge the battery included in the outer covering
and/or the battery of the portable electronic device. In another
example, the outer covering may include a photovoltaic panel in
order to provide power and/or charge the battery included in the
outer covering and/or the battery of the portable electronic
device. In yet another example, a flexible or compliant body may
enable a kinetic charging mechanism that produces power via
physical action such as squeezing.
[0064] The electronic cover 200 can also include one or more
antennas 218. The portable electronic device or the outer covering
can include a transceiver that can be electrically coupled to one
or more antennas so as to receive and transmit electromagnetic
signals.
[0065] FIG. 3 is a block diagram of an electronic system or a
covered electronic device 300 according to one embodiment of the
invention. The covered electronic device 300 includes a cover 302
that covers at least a portion if not a significant portion of an
electronic device 304. The electronic device 304 includes device
electrical circuitry 306. The device electrical circuitry 306 is
electrical circuitry that is associated with the electronic device
304.
[0066] The cover 302 also includes cover electrical circuitry 308.
The cover electrical circuitry 308 is electrical circuitry that is
associated with the cover 302 for the electronic device 304. The
cover 302 may, for example, generally correspond to the cover shown
in FIG. 2. The cover electrical circuitry 308 is, in one
embodiment, formed substantially within the cover 302. For example,
the cover electrical circuitry 308 can be molded within the cover
302. The cover electrical circuitry 308 can be partially or
completely internal to the cover 302. The electronic device 304 is
typically a portable electronic device. The portable electronic
device can, for example, pertain to a portable computer such as a
laptop or tablet computer, or a handheld device such as a digital
assistant, a portable media player, a mobile telephone, a portable
game player, GPS unit, remote control and/or the like. The term
hand-held generally means that the electronic device has a form
factor that is lightweight (e.g., less than about 1 pound (or 0.5
kilograms) and small enough to be comfortably held in one hand.
[0067] Additionally, the covered electronic system 300 is
configured such that a removable interconnection can be established
between the device electrical circuitry 306 and the cover
electrical circuitry 308. Accordingly, when the removable
interconnection is being provided, the device electrical circuitry
306 can make use of, or be augmented by, the cover electrical
circuitry 308. In one embodiment, the removable interconnection can
be provided by a pair of connectors, one connector being part of
the electronic device 304 and another connector being part of the
cover 302 for the electronic device 304. That is, to provide
electrical connection between the device electrical circuitry 306
and the cover electrical circuitry 308, the electronic device 304
can include an electrical connector 310, and the cover 302 can
include a counterpart electrical connector 312. In one example,
when the cover 302 is placed about the electronic device 304, the
electrical connector 310 of the electronic device 304 can receive
the counterpart of electrical connector 312 of the cover 302,
thereby establishing electrical connection between the device
electrical circuitry 306 and the cover electrical circuitry
308.
[0068] The one or more electrical components provided in the cover
302 can be used (i) to extend input/output capabilities of the
portable electronic device, (ii) to augment functional capabilities
of the portable electronic device; and/or (iii) to associate
ornamental aspects to the portable electronic device. The
electronic components can pertain to sensors, connectors,
electronic devices, circuitry (e.g., integrated circuits), or
electrical substrates (e.g., printed circuit boards,
flex-circuits). More specifically, the electronic components
provided in the cover can be or can be used to provide one or more
of: haptics, wireless communication, position navigation, force
feedback, processor, user input device, game player control, light
source, battery, photovoltaic, antenna, data storage, etc.
[0069] FIGS. 4A-4G are diagrammatic illustrations of a portable
electronic device cover 400 according to one embodiment of the
invention. The portable electronic device cover 400 may, for

perspective view of the portable electronic device cover 400, FIG.
4B is a front view of the portable electronic device cover 400,
FIG. 4C is a rear view of the portable electronic device cover 400,
and FIG. 4D is a cross-sectional view of the portable electronic
device cover 400. FIGS. 4E and 4F are alternate rear views of the
portable electronic device cover 200. FIG. 4G is a perspective view
of the portable electronic device cover 400 having an electronic
device contained therein.
[0070] The portable electronic device cover 400 includes an
electrical connector 402 that facilitates connection with an
external connection port on a portable electronic device. When the
portable electronic device cover 400 is placed around a portable
electronic device, the electrical connector 402 can be mechanically
and electrically connected to the external connection port of the
portable electronic device. Consequently, the electrical connector
402 provided within the portable electronic device cover 400 serves
to enable one or more electrical components associated with the
portable electronic device cover 400 to electrically coupled to
electrical circuitry within the portable electronic device. In one
embodiment, the one or more electrical components associated with
the portable electronic device cover 400 pertain to one or more
electrical components provided within the electrical connector 402.
In another embodiment, the one or more electrical components
associated with the portable electronic device cover 400 pertain to
one or more electrical components provided within the portable
electronic device cover 400, where at least one of the one or more
electrical components is not provided within the electrical
connector 402. As shown in FIG. 4B, in one embodiment, the
electrical connector 402 can be positioned at a bottom edge surface
410 of the portable electronic device cover 400. However, more
generally, the electrical connector 402 can be positioned as
appropriate for use with one or more portable electronic
devices.
[0071] In one embodiment, the portable electronic device cover 400
can include a first opening 404 and a second opening 406. The first
opening 404 and the second opening 406 can be provided at a front
surface 408 of the portable electronic device 400. The first
opening 404 within the portable electronic device cover 400 can
facilitate user interaction with the portable electronic device.
The second opening 406 within the portable electronic device can be
commensurate with a display of the portable electronic device that
is being covered by the portable electronic device cover 400.
[0072] FIG. 4C illustrates a rear surface 412 for the portable
electronic device cover 400. In this embodiment, the rear surface
412 has a band portion 414 that extends around the periphery of the
rear surface 412. In this embodiment, the rear surface 412 has a
large opening 416 given that the band portion 414 extends inward
from the edge of the periphery to a minimum extent. The opening 416
allows the portable electronic device to be inserted into the
portable electronic device cover 400 and connected with the
electrical connector 402.
[0073] FIG. 4D illustrates a cross-sectional view of the portable
electronic device cover 400 with reference to reference line A-A'
shown in FIG. 4C. The portable electronic device cover 400 forms a
cavity 418. The portable electronic device can be received in the
cavity 418. Typically, when the portable electronic device is
provided within the cavity 418, the cavity is substantially
consumed by the portable electronic device. In one embodiment, the
cavity 418 can be configured to correspond to the external shape of
the portable electronic device. The portable electronic device
cover 400 can, for example, be formed from hard plastic or soft
rubber or silicone. In the same or another embodiment, the cavity
418 can be conformable (e.g., form-fitting) to the external shape
of the portable electronic device. The cavity 418 is conformable
when the portable electronic device cover 400 is formed from a
conformable material, such as rubber, silicone, etc.
[0074] FIG. 4E illustrates an alternative rear surface 412' for the
portable electronic device cover 400. In this embodiment, the rear
surface 412' has a band portion 414' that extends around the lower
periphery of the rear surface 412'. In this embodiment, the rear
surface 412' has a covered portion 415 at an upper periphery of the
rear surface 412' and an opening 416' formed at a lower portion of
the rear surface 412'. The opening 412' is formed at the lower
portion by the band portion 414' extending inward from the edge of
the periphery to a minimum extent. The opening 416' allows the
portable electronic device to be inserted into the portable
electronic device cover 400 and connected with the electrical
connector 402. In still other embodiments, the opening 416' can be
smaller and positioned elsewhere, such as at an edge.
[0075] FIG. 4F illustrates an alternative rear surface 412'' for
the portable electronic device cover 400. In this embodiment, the
rear surface 412'' does not have a band portion but rather includes
a fully enclosed rear surface 412''. In this embodiment, the rear
surface 412'' has a covered portion 415' from edge to edge. The
portable electronic device may be placed within the portable
electronic device cover 400 (e.g., into the cavity 418) via an
existing opening such as, for example, the first opening 404 or the
second opening 406.
[0076] FIG. 4G is a perspective view of the portable electronic
device cover 400 having a portable electronic device 420 contained
therein. The perspective view illustrated in FIG. 4G is the same as
the electronic device cover 400 illustrated in FIG. 4A.
Additionally, in FIG. 4G, the portable electronic device cover 400
is placed over (e.g., encloses) the portable electronic device 420.
When the portable electronic device cover 400 is placed around the
portable electronic device 420, the electrical connector 402 can be
mechanically and electrically connected to the external connection
port of the portable electronic device 420. Consequently, the
electrical connector 402 provided within the portable electronic
device cover 400 serves to enable one or more electrical components
associated with the portable electronic device cover 400 to
electrically coupled to electrical circuitry within the portable
electronic device 420.
[0077] In an alternative embodiment, the first opening 404 and/or
the second opening 406 can contain a material. In one
implementation, the material can be a thinner layer of material
than that used for the portable electronic device cover 400. In
another implementation, the material can be substantially or
completely translucent. In still another implementation, the
material can have depressions or features. For example, the
depressions or features can assist with user input.
[0078] FIGS. 5A-5D are partial side elevation views of a portable
electronic device cover 500 according to several embodiments of the
invention. The portable electronic device cover 500 may, for
example, generally correspond to those previously mentioned covers
or electronic covers. In each of these figures the electronic
components 502 are at least partially embedded or formed into a
portion of the cover body 504. Put another way, the electrical
components 502 are at least integral with the cover body 504 (e.g.,
integrated). The electrical components 502 may be selected from any
of those described previously and although only a single component
is shown, it should be appreciated that the techniques described
may apply to multiple components. Furthermore, when dealing with
multiple components, any combination of FIGS. 5A-5H may be used. In
all of these combinations it can be said that the electrical
components share a common cover body. It should also be appreciated
that the electrical components can be on the same or different
walls of the cover body. For example, electrical components can be
placed relative to front walls, rear walls, side walls, top walls
and/or bottom walls using one or a combination of the embodiments
described with reference to FIGS. 5A-5D.
[0079] FIG. 5A shows the electrical component 502 completely
disposed within the cover body 504 (e.g., enclosed internally). The
electrical component 502 may, for example, be embedded in the cover
body 504. In one example, the cover body 504 is formed or molded
around the electrical component 502.
[0080] FIG. 5B shows the electrical component 502 disposed within
the cover body 504, but partially exposed at the inside surface
(may be protruding, recessed or flush). In some cases, the
electrical component 502 can be recessed or flush with the inside
surface to prevent contact with the portable electronic device. In
some cases, as for example, where contact is desired (electrical
contact), the electrical component 502 may protrude.
[0081] FIG. 5C shows the electrical component 502 disposed within
the cover body 504, but partially exposed at the outside surface
(may be protruding, recessed or flush). In some cases, the
electrical component 502 can be recessed or flush with the outside
surface to prevent contact with the portable electronic device. In
some cases, as for example, where contact is desired (electrical
contact), the electrical component 502 may protrude.
[0082] FIG. 5D shows the electrical component 502 disposed within
the cover body 504, but partially exposed at the inside and outside
surfaces (may be protruding, recessed and/or flush on each
side).
[0083] The cover body 504 shown in FIGS. 5A-5D can be formed from
multiple layers. For example, the multiple layers can include an
external member and an internal member. The electrical component
502 may be sandwiched between, disposed within one of the members,
and/or partially disposed within both members. These layers may be
attached or integrally formed (e.g., double shot).
[0084] In accordance with one embodiment, the body shown in FIGS.
5A-5D may be formed from a soft, flexible and/or compliant material
that can be wrapped around the various surfaces of the portable
electronic device. For example, the material may allow the covering
to stretch over the portable electronic device (e.g., form
fitting). By way of example, the outer covering may be formed from
a stretchable material that includes a small opening that can be
stretched to accommodate the larger portable electronic device as
it is inserted into the outer covering. Once the portable
electronic device is inserted, the material confirms to the shape
of the portable electronic device, which provides a tight fit
around the surfaces of the portable electronic device. The outer
covering may, for example, surround multiple side surfaces if not
all of the side surfaces of the portable electronic device. In one
particular example, the material may be rubber or silicone
materials. These type of coverings are sometimes referred to as
"skins" as they create a new outer layer analogous to skin. It
should be appreciated however that other materials may be used.
[0085] FIG. 6A-6D are diagrammatic illustrations of a portable

is shown embedded in the connector body 602. One or more wires 610
can also be provided internal to the connector body 602 to connect
the at least one electrical component 608 to the receptacle 604 and
the extension 606. The electrical connector 600 can pertain to a
peripheral connector. Typically, the electrical connector 600 will
have a plurality of electrical contacts (e.g., pins). The
electrical connector 600 can be embodiment is various ways, such as
a flat multi-pin connector (e.g., 30-pin connector), a plug with
multiple electrical contact regions, or a peripheral bus connector
(e.g., USB or Firewire..TM..).
[0087] FIG. 6C is an end view of a portable electronic device cover
620 according to one embodiment of the invention. The portable
electronic device cover 620 has an outer surface 622 and an inner

604 can be accessible from the end of the portable electronic
device cover 620. The extension 606 of the electrical connector 600
is also accessible internal to the cavity so that connection with a
counterpart connector of the portable electronic device can be
made.
[0088] FIG. 6D illustrates a rear surface 626 for the portable
electronic device cover 620 according to one embodiment of the
invention. In this embodiment, the rear surface 626 of the portable
electronic device cover 620 has a band portion 628 of the portable
electronic device cover 620 that extends around the periphery of
the rear surface 626. In this embodiment, the rear surface 626 has
a large opening 630 given that the band portion 628 extends inward
from the edge of the periphery to a minimum extent. The opening 630
allows the portable electronic device to be inserted into the
portable electronic device cover 620 and connected with the
extension 606 of the electrical connector 600. The electrical
connector 602 is at least partially embedded at an end 632 of the
portable electronic device cover 620. In other embodiments, the
rear surface 626 of the portable electronic device cover 620 can
alternatively be embodied as illustrated in any of FIG. 4C, 4E or
4F.
[0089] FIG. 7 is a perspective diagram showing a portable device
cover 700 in accordance with one embodiment of the invention. The
portable device cover 700 can be similar to that shown in FIGS. 2,
3, 4A-4G and 6A-6D. The portable device cover 700 includes a cover
body 702. Besides including a connector 704, the cover body 702
also includes at least one electrical component 706 positioned
within the portable device cover 700. While the connector 704 may
be found in a first wall of the cover body 702, the electrical
component 706 may be found in a second wall. By way of example, the
connector 704 may be disposed in a bottom wall while the electrical
component 706 may be found in front, rear, top and/or side walls.
The electrical component 706 may be operatively coupled to the
connector 704 so as to allow communications and/or signaling to
occur between the electrical component 706 and the portable
electronic device when inserted into the portable device cover 700.
This may be accomplished using a variety of techniques including
but not limited to wires, traces, flex circuits, rigid flex,
circuit boards and/or the like. Any combination of elements may be
used. These lines may be configured into the portable device cover
700 similar to that of the electrical components 706, such as
discussed in FIG. 5A-5D.
[0090] FIG. 8 is a perspective diagram showing a portable device
cover 800 in accordance with one embodiment of the invention. The
portable device cover 800 can be similar to that shown in FIGS. 2,
3, 4A-4G and 6A-6D. The portable device cover 800 includes a cover
body 802. Besides including a connector 804, the cover body 802
also includes at least one electrical component 806 positioned at

components 806 may be found in front, rear, top and/or side walls.
In this embodiment, the portable device cover 800 includes multiple
and discrete electrical components 806 positioned at different
locations about the cover body 802. For example, a first electrical
component may be found in a first wall and a second electrical
component may be found in the same wall but at different location
or may be found on a different wall altogether. By way of example,
as shown in FIG. 8, a bottom wall includes the connector 804, a
front wall includes a first, second and third electrical components
806, and a side wall includes a fourth electrical component 806.
The electrical components 806 may be operatively coupled (i.e.,
directly or indirectly connected) to the connector 804 so as to
allow communications and/or signaling to occur between the
electrical components 806 and the portable electronic device when
inserted into the portable device cover 800. This may be
accomplished using a variety of techniques including but not
limited to wires, traces, flex circuits, rigid flex, circuit boards
and/or the like. Any combination of elements may be used. These
lines may be configured into the portable device cover 800 similar
to that of the electrical components 806, such as discussed in FIG.
5A-5D.
[0091] It should be appreciated that although a connector is
provided in the embodiments shown in FIGS. 7 and 8, there are
alternative ways besides the connector for electrical components
within a cover body of a portable device cover to communicate with
a portable electronic device provided within the portable device
cover. For example, as mentioned earlier, wireless connections may
also be used. In some cases, some of the electrical components
within the cover body can communicate through a connector while
others communicate wirelessly. Alternatively or additionally, the
portable device cover may include multiple connectors.
[0092] The electrical interconnections or routing between
electrical components (including connectors) can vary with
implementation and can depend on the desired configuration of the
cover and portable electronic device. FIGS. 9A, 9B and 9C show
operative coupling between multiple electrical components in
accordance with certain embodiments of a portable device cover 900.
As shown in FIG. 9A, the electrical components 902 may be embedded
in the cover 900 and interconnected with electrical leads, wires or
traces 904 also within the cover. As shown in FIG. 9B, the
electrical components 902 may be embedded in the cover 900 but be
operatively coupled via leads, wires or traces 904 that are at
least partially outside the cover 900. In some cases, there may be
an insulation layer provided within a wall of the cover 900. As
shown in FIG. 9C, an intermediate layer 910 may be disposed between
an inner layer 906 and an outer layer 908 of a wall. The
intermediate layer 910 can be an insulative or filler material. The
intermediate layer 910 can thus surround and support the electrical
components 902 and the electrical leads, wires or traces 904 placed
in between the inner layer 906 and the outer layer 908.

produce an ornamental appearance for the cover 1060. For example,
the illumination devices can be used to impart different colors to
different parts of the cover 1060 so as to colorize the cover 1060,
display an image, or display light effects. Fiber optics (e.g.,
fiber optic strands) can also be used within the cover 1060 to
route light for illumination purposes. The material used for the
cover 1060 can also be used to diffuse the light produced by the
illumination elements. In one embodiment, the electronic grid 1062
is completely embedded in the cover 1060. The electronic grid 1062
can be connected to a connector 1064 by electrical conductors
(e.g., wires). The connector 1064 can be used to electrically

[0098] FIGS. 11A-11D illustrate an interconnection system for a
portable electronic device 1100 and a cover 1102 according to one
embodiment. The portable electronic device 1100 includes one or
more recessed contacts 1104. The recessed contacts 1104 can be
provided on an surface of the housing of the portable electronic
device 1100. For example, in one embodiment, the recessed contacts
1104, namely conductive metal contacts, are provided on a back
surface of the portable electronic device 1100. FIG. 11A
illustrates a back view for the portable electronic device 1100,
and FIG. 11C illustrates a side view for the portable electronic
device 1100. FIG. 1102 illustrates a surface of the cover 1102, and
FIG. 11D illustrates a side view for the cover 1102. The cover 1102
for use with the portable electronic device 1100 can be provided
with one or more exposed contacts 1106. The exposed contacts 1106
can be provided on an inner surface of the cover 1102 that abuts
against the surface of the portable electronic device 1100 having
the recessed contacts 1104 when the cover 1102 is provided on the

protruding outward from the inner surface of the cover 1102 so as
to engage and make electrical contact with the recessed contacts
1104. The exposed contacts 1106 can be shaped or biased so provide
a reliable electrical connection with the recessed contacts 1104.
The exposed contacts 1106 can be formed from conductive metal.
[0099] In the embodiment illustrated in FIGS. 11A-11D, the recessed
contacts 1104 are a set of aligned and spaced apart contact pads
having a bar-shaped configuration. The exposed contacts 1106 can
have a similar configuration and may be biased to ensure proper
contact when mating with the corresponding recessed contacts 1104.
This may, for example, be accomplished with flexure or spring-like
contacts. Alternatively, the exposed contacts 1106 of the cover
1102 may be positioned on a flexible bump of the under surface. The
flexible bump may, for example, be an integrally molded portion of
the cover 1102. It should be appreciated that the cover 1102 may
include an alignment feature to ensure proper contact. In some
cases, the alignment feature may simply be multiple surfaces of the
cover, i.e., the multiple surfaces self-align the contacts when the
covering and portable electronic device are mated.
[0100] The various electrical components may be individually
situated relative to the cover or they may be grouped and placed on
a carrier (or substrate), such as a circuit board.
[0101] In one embodiment, the cover can includes one or more
electronic subassemblies that are embedded with the cover. A
subassembly is a multi-part electronic component, such as a
electronic circuit, integrated circuit or substrate (e.g., PCB,
flex circuit). The cover may, for example, be formed from a rubber
or silicone material. The electronic subassemblies may be embedded
within the cover using for example insert molding techniques.
Although the electronic subassemblies are embedded, at least a
contact portion can be exposed so that the subassemblies can be
interconnected. For example, the subassemblies and controller may
include a series of exposed pads or pins. In one particular
embodiment, the subassemblies are externally connected through
wires, flex circuits or traces that run along an exposed surface of
the covering. For example, the connections can be provided by
traces that are printed on the exposed surface of the cover. The
traces may subsequently be covered with a dielectric coating to
provide protection and/or electrical isolation. The subassemblies
may be formed in a variety of ways and include a variety of
electronic components. In one example, a subassembly can include a
controller which can pertain to a controller or processor chip,
individually or mounted on a substrate, such as a printed circuit
board. The controller may also include a connector that is
integrated therewith, such as attached to the same substrate.
[0102] In another embodiment, the subassemblies as well as the
wires, flex circuits or traces are all embedded within the cover.
In one implementation, the subassemblies and their interconnections
can be established before being embedded within the cover. To
implement this embodiment, the subassemblies and interconnections
(e.g., wires, traces or flexible circuits) can, for example, be
mounted on a substrate, such as a flex circuit, rigid flex or
PCB.

components 1204, 1206 and 1208 are electrically connected, directly
or indirectly, to the connector 1202. However, in one embodiment as
shown in FIG. 12A, the electrical component 1204 is connected to
the connector 1202, the electrical component 1206 is connected to
the electrical component 1204 via conductors 1210, and the
electrical component 1208 is connected to the electrical component
1208 via conductors 1212. The electrical components 1204, 1206 and
1208 can, for example, pertain to integrated circuits, electronic
circuits, sensors, electronic devices (display, touch sensitive
devices, user input devices, etc.), or substrates (printed circuit
boards, rigid or flexible). The electrical components 1204, 1206
and 1208 as well as the conductors 1210 and 1212 can be provided
internal to the cover 1200 or can be provided on an inner surface
of the cover. For internal placement, the electrical components
and/or conductors can be formed in the cover when the coved is

components. The electrical components 1226 can, for example,
pertain to integrated circuits, electronic circuits, sensors,
electronic devices (display, touch sensitive devices, user input
devices, etc.), or substrates.
[0105] In one embodiment, the carrier (or substrate) is flexible
especially in embodiments where the covering is flexible and/or
compliant. In addition, flexible and compliant embodiments may
space the electrical components such that the body remains flexible
and/or compliant. This may for example be accomplished as discrete
components attached through traces or wires or via a flex circuit.
If the components are too closely spaced they may make the body
somewhat rigid thereby making it difficult to stretch or conform to
a surface of the portable electronic device.
[0106] In one embodiment, traces for routing the various components
about the cover are provided on the internal surface of the cover.
By way of example, they may be applied as a coating that is
deposited or painted in the desired pattern. In one implementation,
the components are molded into the cover with contacts left exposed
on the internal surface. Thereafter, the traces are applied to the
internal surface to connect the various components. By way of
example, the traces may provide connections between a controller
and various Input/Output (I/O) features and between the controller
and a connector. Alternatively or additionally, the traces may
provide direct connections between the I/O features and the
connector. In one embodiment, a compliant cover is molded with
electrical components and thereafter it is folded inside out so
that the traces can be applied to the internal surface. In some
cases, a cover layer (e.g., dielectric layer) may be applied over
the traces to protect and/or electrically isolate the traces. By
way of example, a dielectric coating may be applied over the traces
(similar pattern) or it may cover a majority of the surface thereby
ensuring that the traces are covered.
[0107] In one embodiment, the cover may include one or more
openings for providing access to a feature of the portable
electronic device when the portable electronic device is being
surrounded by the cover. One such opening may, for example, provide

thereafter fully enclosed by the second layer being applied to the
first layer.
[0130] In one embodiment, a cover can pertain to a phone cover. The
phone cover is configured to add phone functionality when coupled
to a portable electronic device that does not include phone
functionality. The portable electronic device may, for example, be
a portable media player, such as an IPod..TM.. manufactured by
Apple Inc. of Cupertino, Calif. The material for the phone cover be
widely varied. In one embodiment, the material for the phone cover
is a compliant, deformable or elastic and wraps around the portable
electronic device. The phone cover may, for example, include an
inner cavity that has an inner shape that substantially coincides
with the outer shape of the portable electronic device when the
phone cover is placed over the portable electronic device. The
compliant skin can be formed from a variety of materials. In one
embodiment, the phone cover is formed from silicon rubber.
[0131] The phone cover can include an opening or transparent window
that provides viewable access to a display screen of the portable
electronic device. The phone cover may also include an input area
that at least designates a keypad region. The keypad region may
include a keypad with integrated mechanical or electronic actuators
or alternatively it may include visual and/or tactile elements that
utilize an input device of the portable electronic device. In one
example, the tactile elements are configured to engage an input
device disposed on the portable electronic device. The input device
may, for example, be a touch wheel/button found on some iPod
devices. The keypad region generally includes number keys and # and
* keys found on most phones. The keypad region may also include a
talk or enter button. Other phone related buttons such as speaker
and mute may also be provided. In one implementation, the keypad is
arranged in a matrix or rows and columns. In another
implementation, the keypad is arranged around a circle similar to
old rotary telephones. The tactile features may be recesses or
protrusions. In one example, the tactile features are depressible
bumps.
[0132] The phone cover may include a connector for interfacing the
electrical components within the portable electronic device. The
phone cover can also include a built-in speaker and microphone. The
speaker typically interfaces with the user's ear while the
microphone typically interfaces with a user's mouth. Thus, the
speaker is typically placed in an upper portion of the phone cover
and the microphone in a lower portion of the cover.
[0133] Although not required, the phone cover may also include a
proximity detector. The proximity detector may be used to detect
when a user places the cover/electronic device up to their face.
The phone cover can also include a speaker phone that allows audio
data to be externally output. Still further, the phone cover can
also include one or more of: a controller, an antenna, a camera, a
connector, one or more switches, an opening for a power/hold
switch, and an opening for an audio/video jack.
[0134] FIG. 17A is a diagram of a front surface of a cover 1700 for
a portable electronic device according to one embodiment. The front
surface of the cover 1700 is provided with various user interface
components to adapt the portable electronic device to operate as a
mobile telephone. The cover 1700 includes an opening 1702 for
access to a display/touch screen of the portable electronic device,
and an opening 1704 for access to a button of the portable
electronic device. The cover 1700 can include a plurality of
buttons 1706 that are provided around the opening 1704. The buttons
1706 permit the user to enter inputs to the portable electronic
device. The buttons 1706 can be implemented by switches or sensors.
Although various arrangements can be used, the buttons 1706 are
arranged in a ring so as to resemble a rotary dial, with the
buttons 1706 representing numbers 0-9. The cover can provide
tactile features to denote each of the buttons 1706. The cover 1700
can also include a speaker 1708 and a microphone 1710. The cover
1700 can further include a proximity sensor 1712 to detect when the
cover 1700 is held proximate to a user's head. Still further, the
cover 1700 can include one or more switches 1714. Although
placement can vary, the switches 1714 are provided on a side
surface of the cover 1700.
[0135] FIG. 17B is a diagram of a back surface of the cover 1700
illustrated in FIG. 17A. In this embodiment, the back surface does
not include any user interface components. However, in general, the
back surface is eligible to include user interface components. In
this embodiment, the back surface has various electrical components
embedded therein. In particular, as illustrated in FIG. 17B, the
cover 1700 include a connector 1716 that facilitates electrical
connection of the cover 1700 with the portable electronic device.
Internal to the back surface are a substrate 1718 (e.g., flex
circuit, PCB) that has at least a controller 1720 and wireless
circuitry 1721 mounted thereon, electrical conductors 1722, a
camera 1724, one or more electrical conductors 1726, and an antenna
1728. The substrate 1718 is electrically connected to the connector
1716, and the controller 1720 and the wireless circuitry 1721 are
or include one or more integrated circuit products (e.g.,
integrated circuit chips) attached to the substrate 1718. Other
electrical components can also be attached to the substrate 1718.
The electrical conductors 1722 serve to electrically connect the
switches 1714 to the substrate 1718. The camera 1724 provides the
cover 1700 with image capture capabilities. The one or more
electrical conductors 1726 serves to electrically connect the
camera 1724 with the substrate 1718. The antenna 1728 is coupled to
the substrate 1718 and serves to support the wireless circuitry
1721 with transmission and reception of wireless signals.
[0136] In one embodiment, a cover for a portable electronic device
can provide a graphical user interface of a game controller. The
game controller acts as a game controller adapter. The game
controller can be independent of fixed user input devices (e.g.,
touch screen) of the portable electronic device or can make use of
the fixed user input device of the portable electronic device.
[0137] In one embodiment, a cover includes a built-in touch surface
on its back surface. In one implementation, the touch surface
substantially matches up with a display screen of a portable
electronic device on the opposite side.
[0138] In one embodiment, a cover includes one or more suction cups
on its back surface so that a portable electronic device being
covered can be attached to a surface. For example, using the cover,
the portable electronic device may be mounted onto a wall or other
surface (e.g., a food tray in an airplane).
[0139] In one embodiment, a cover for a portable electronic device
can include a built-in haptic system. The haptic system may include
a plurality of discrete haptic nodes capable of providing discrete
haptic feedback, i.e., local feedback in the region of the node.
The nodes may for example be piezo actuators. The haptic nodes can
be placed throughout the cover or can be provided in limited
areas.
[0140] In one embodiment, a cover for a portable electronic device
can includes a camera (e.g., video camera) on its front surface.
The camera may enable video/online conferencing or chatting via a
handheld electronic device.
[0141] In one embodiment, a cover for a portable electronic device
can include one or more embedded antennas. The one or more antennas
can support access to wireless networks, such as cellular, WiFi or
Bluetooth, etc.
[0142] In one embodiment, a covering for a portable electronic
device is formed from a compliant or deformable material such that
it can be squeezed. The cover may include a kinetic charging system
embedded within the cover and configured to produce energy when the
compliant covering is squeezed. The energy may be used to charge
and/or power the portable electronic device. By way of example, the
user may continuously perform a squeezing action in order to charge
the battery of the portable electronic device.
[0143] In one embodiment, a cover for a portable electronic device
includes photovoltaic components, which can be provided as a
photovoltaic module. The energy produced by the photovoltaic
components may be used to charge and/or power the portable
electronic device.
[0144] In one embodiment, a cover for a portable electronic device
can include a built-in accelerometer and one or more electronically
controlled shock mounts. When the cover or portable electronic
device senses a drop event using the accelerometer, the shock
mounts can be electronically controlled to change from a normal use
state to a drop event state so as to operate to protect the
portable electronic device against impending impact.
[0145] In one embodiment, a cover for a portable electronic device
includes a built-in battery. The battery in the cover can thus
provide auxiliary power for the portable electronic device. The
battery may or may not be removable from the cover. Typically,
however, the battery is rechargeable.
[0146] A cover may serve as an outer membrane. The outer membrane
may be widely varied. In one embodiment, the outer membrane is a
compliant, deformable or elastic skin that wraps around a portable
electronic device. The compliant or elastic skin may for example
include an inner cavity that has an inner shape that substantially
coincides with the outer shape of the portable electronic device
when the skin is pulled over the portable electronic device. The
compliant skin can be formed from a variety of materials. In one
embodiment, the skin is formed from silicon rubber. As discussed
above, the outer membrane can include a plurality of embedded
components as well as a plurality of embedded interconnects that
couple the embedded components together. The interconnects may, for
example, be wires, traces or flex circuits.
[0147] The outer membrane also includes a partially embedded
connector that provides an interface between the electrical
components and the portable electronic device that is placed within
the cavity of the outer membrane. The connector is operatively
coupled to the electrical components and is configured to mate with
a corresponding connector to allow communications there between.
The connector includes a first contact portion that is exposed
within the cavity for interfacing with the portable electronic
device. In some cases, the connector may also include a second
contact portion that is exposed on the outside surface of the
membrane and serves as an external connector.
[0148] In one embodiment, a cover is formed of a flexible material.
It may for example be a bendable or stretchable sheet, enclosure or
sleeve. Examples of suitable flexible material include mylar,
vinyl, polyester, rubber, fabric, foam, plastic films, etc.
[0149] In one embodiment, a cover can be formed from an elastomeric
material. Elastomeric materials are capable of resuming their
original shape after stretching or compression. As such, a cover
may provide support and conform to the shape of the portable
electronic device (e.g., it can fit tightly around a portable
electronic device). The cover may, for example, be configured as an
enclosure or sleeve into which the portable electronic device is
placed for scratch prevention, impact protection and contamination
control. The enclosure may, for example, be a multi-walled
structure that defines a cavity that conforms to the shape of the
portable electronic device. In one example, the shape of the inner
cavity of the enclosure substantially coincides with the outer
shape of the portable electronic device. The enclosure may fully
surround, surround a majority, or only surround a small portion of
the portable electronic device. Be cause its elastomeric, the cover
can stretch such that an opening to the cavity can be smaller than
the dimensions of the portable electronic device itself. The
material simply stretches to make way for the portable electronic
device being inserted and then resumes to its original shape
thereby wrapping itself about the portable electronic device. In
some cases, this type of configuration is called a "skin."
[0150] The elastomeric material may be formed from elastic polymers
such as those known as elastomers. Elastomers are typically
thermosets but may also be thermosets. The elasticity can be
controlled via transition temperatures of the material selected. In
one implementation, the material may be manipulated at a first
temperature range to produce less elasticity or at another
temperature range to produce high elasticity. The level of
elasticity is typically dependent on the needs of the cover.
[0151] In one embodiment, a cover can be formed from elastic
rubbers (natural and/or synthetics). In one particular
implementation, the material for the cover is silicon rubber
(silicone rubber). Silicon rubber is inexpensive, and has good
resistance to temperature, UV and other aging factors. It is also
an inert material and thus it also has good resistance to most
chemicals. Furthermore, it can be made highly elastic. Silicon
rubber may include a variety of filler to adjust its properties and
colors. Silicon can also be formulated as special grades with
special attributes. In addition, silicon can be easily formed into
a variety of shapes.
[0152] In one embodiment, a cover can be formed of a hard plastic.
For example, the cover can be formed of polycarbonate or ABS
plastic.
[0153] In one embodiment, a cover can be formed of a translucent
material.
[0154] Various techniques may be used to form the desired shape of
a cover including for example molding or casting techniques.
Various molding techniques include compression molding, transfer
molding, injection molding, and the like. Some techniques that may
be useful to integrate electronics into the molded part include
insert molding and/or double shot injection molding. These and
other embodiments will be described in greater detail below.
[0155] In one embodiment, electrical components (as well as other
structures) may be suspended within a mold, and the material may be
allowed to be placed around it such that the electrical components
are at least partially and possibly fully embedded within the walls
of the cover. In some cases, select portions may be left exposed
during molding. In other cases, select portions may be exposed in
post molding operations (e.g., stamping, cutting). In either case,
the exposed portions may be included for making post mold
connections (e.g., between embedded components or between the cover
and the portable electronic device). In one example, insert molding
techniques may be used. During insertion molding, the mold is
loaded with some or all of the electronic structures of the cover.
Thereafter, material is forced into the mold (e.g., hot molten
material is injected). After allowing the part to cool, the mold is
opened and the product is removed. Thereafter, post molding
operations are performed. For example, access openings if not part
of the molded design are formed using a variety of techniques such
as stamping or cutting. In addition, additional structures may be
attached to the cover including, for example, more components
and/or wires or traces that couple components. By way of example,
portions, such as contacts, of the embedded structures may be
exposed and traces may be printed on the surface of the cover
between components such that they are operatively connected. The
circuits may then be tested. Printing of traces and testing may be
performed by folding the cover inside out. Thereafter, any
remaining exposed structures (other than the connection point
between the cover and the portable electronic device) may be
covered up through use of coatings, epoxies, labels or more cover
material. It should be appreciated that other structures may be
insert molded including for example attachment mechanisms and/or
ornamental features.
[0156] Alternatively or additionally, a cover may be formed from
multiple layers that are applied successively. For example, the
cover may be formed from a first layer and a second layer, both of
which can be formed using successive molding operations. In on
example, the first layer is formed. This may include no structure,
partially embedding one or more structures, or fully embedding one
or more structures. Thereafter, if desired, more electronic parts
can be added as, for example, by attaching to an inner surface of
the first layer. Also, traces, wires, or flex circuits can be added
thereby making connections between components. Testing can also be
performed. Thereafter, a second layer is formed over the first
layer and over exposed electronics or circuitry (except the
connection mechanism between the cover and portable electronic
device remain exposed). In one implementation, a double shot
injection molding techniques can be used. Double shot molding is a
process for producing two integral parts by utilizing successive
molding methods. In one example, material is forced into a first
mold to form a first layer. Thereafter, either a half of the mold
or the part is transferred to another mold (thereby acting as an
insert). Thereafter material is forced into the second mold to form
a second layer that integrally affixes to the first layer. In some
cases, the same material is used. In other cases, different
materials or the same material with different properties is
used.
[0157] In some cases, exposed parts may be covered instead of or in
addition to double injection molding. The covering applied may be
provided by coatings, epoxies, paints, films and the like.
[0158] In one embodiment, a cover may also be formed as a laminate
part. For example, the cover may include an outer layer (e.g.,
flexible sheet or label), one or more components attached thereto,
and an inner adhesion layer. The adhesion layer allows the laminate
structure to be attached to an outer surface of a portable
electronic device. The components may include wires or traces as
mentioned above. Furthermore, in order to provide a uniform cover,
a filler may be included between the outer and inner layers between
the components
[0159] FIG. 18 is a flow diagram of a cover formation process 1800
according to one embodiment of the invention. The cover formation
process 1800 is suitable for forming a protective cover having an
electrical component.
[0160] The cover formation process 1800 provides 1802 a mold for a
protective cover for an electronic device. Here, a mold can be
created to form the protective cover. The protective cover will
eventually be utilized to cover a significant portion of an
electronic device. An electrical component to be provided in the
protective cover is also obtained 1804. As discussed above, the
electrical component can take many forms and can be positioned in
the protective cover at various locations. Next, the electrical
component can be positioned 1806 with the mold. By positioning in
the electrical component within the mold, the electrical component
can be placed at a particular location with respect to the
protective cover to be formed. Thereafter, the protective cover can
be formed 1808 using the mold. For example, a molding compound can
be injected into the mold, allowed to cure and then removed from
the mold. The cured molding compound forms the protective cover
whereby the electrical component is secured or embedded in the
molding compound that forms the protective cover. Following the
formation 1808 of the protective cover, the cover formation process
1800 can end.
[0161] In one embodiment, the electronic device to be covered may
further be a hand-held electronic device. The term hand-held
generally means that the electronic device has a form factor that
is lightweight (e.g., less than about 1 pound (or 0.5 kilograms)
and small enough to be comfortably held in one hand. A hand-held
electronic device may be directed at one-handed operation or
two-handed operation. In one-handed operation, a single hand is
used to both support the device as well as to perform operations
with the user interface during use. In two-handed operation, one
hand is used to support the device while the other hand performs
operations with a user interface during use or alternatively both
hands support the device as well as perform operations during use.
In some cases, the hand-held electronic device is sized for
placement into a pocket of the user. By being pocket-sized, the
user does not have to directly carry the device and therefore the
device can be taken almost anywhere the user travels.
[0162] The one or more electronic subassemblies that are part of
the outer covering may be widely varied. The electronic
subassemblies may include one or more electronic components such as
integrated circuits (i.e., chips), circuit boards, flex circuits,
wires, Light Emitting Diodes (LEDs), electronic circuits, switches,
and other circuitry. The electronic subassemblies may, for example,
extend Input/Output (I/O) of the portable electronic device into
the covering (e.g., visual indicators, display, audio, tactile,
haptics, buttons, switches, detectors, touch pads, navigation pads,
joysticks, keys, etc). Additionally or alternatively, the
electronic subassemblies may, for example, be associated with one
or more sensors include for example accelerometers, GPS, proximity,
biometric, force and/or the like that extend the capabilities of
the portable electronic device. Additionally or alternatively, the
electronic subassemblies may, for example, be associated with a
connection interface (e.g., mechanical connector, inductance,
wireless). Additionally or alternatively, the electronic
subassemblies may, for example, be associated with memory, CPU or
processing capabilities, battery, solar charging, kinetic charging,
antenna (multiple selectable antennas, supplemental antennas,
boosters, etc.), and others. Additionally or alternatively, the
electronic subassemblies may, for example, be associated with
software upgrades or new software applications. For example, the
outer covering may include a memory device including a new software
application with a new I/O dedicated to the new application.
Additionally or alternatively, the electronic subassemblies may,
for example, be associated with card slots as for example SIMM
cards, flash cards, memory cards, game cards, etc.
[0163] The subassemblies may be operatively coupled to the portable
electronic device via wired or wireless connections. If wired, at
least one of the subassemblies may be associated with or coupled to
a connector that plugs into or otherwise mechanically interfaces
the portable electronic device. The connector may, for example, be
a data and/or power connector. The connector may include various
pins or contacts that support various signals. Examples include
USB, Firewire that include 4-6 pins. Other examples include
connectors with larger pin layouts such as for example the 30 pin
connector that support iPods and iPhones manufactured by Apple Inc.
of Cupertino, Calif. In one implementation, the connector includes
a first connector that mates with the portable electronic device
and a second connector that extends the portable electronic
device's connector to the outside of the outer covering (e.g.,
male/female connectors). For wireless capabilities, the
subassemblies may include one or more various chipsets that support
wireless functionality of the portable electronic device including
for example Bluetooth, 802.11, RF, IR, etc.
[0164] In one implementation, the outer covering is compliant and
the one or more subassemblies and associated circuitry are at least
partially embedded within the compliant outer covering. For
example, the material may be molded around a portion of the
subassembly including associated circuitry and wiring such that the
subassembly and the outer covering become a single integral unit.
In one example, insert molding techniques are used to mold around
the various subassemblies. The subassemblies may be fully embedded,
embedded with an exposed internal surface or feature, or embedded
with an exposed external surface or feature, or embedded with an
exposed internal and external surface or feature. Additionally or
alternatively, the subassemblies may be applied to the surfaces of
the outer covering rather than being fully or partially enclosed
within the outer covering. For example, the subassemblies may be
attached to an internal surface of the outer covering and, the
subassemblies may be attached to an external surface of the outer
covering. As should be appreciated, any combination of embedded and
surface mount may be used to achieve the desired effect. For
example, in one embodiment, the subassemblies are only embedded. In
another embodiment, the subassemblies are only surface mounted. In
yet another embodiment, the subassemblies are both embedded and
surface mounted.
[0165] When the outer covering is flexible or compliant, the
subassemblies may be configured to facilitate or allow
flexing/stretching. For example, the subassemblies may be spaced
apart or spread out such that the compliant material is able to
stretch. In other examples, the subassemblies may be formed as
small components or broken up into smaller components thereby
reducing the rigidity of the entire system. In other examples, the
wires that connect subassemblies may include some slack such that
during stretching or flexing they do not become a pinch point to
the flexibility of the entire system.
[0166] In some cases, the outer covering may be user configurable
such that they select the desired subassemblies when
purchasing/ordering the outer covering. In one example, the user
may create a customized I/O. The outer shape may also be user
configurable for example the outer covering may be form fitted to a
user's hand shape (making it more ergonomic).
[0167] In some cases, the outer covering may be replaceable or
disposable. For example, it may include a one time use disposable
battery. In some cases, the outer covering may be upgradeable. For
example, it may include standardized attachment points or regions
where mechanical and/or electronic and/or optical systems may be
connected.
[0168] A connection interface that may be provided between a
portable electronic device and a cover (outer covering). In one
embodiment, the portable electronic device includes an exposed
connector on one of its outer surfaces and the cover includes a
corresponding exposed connector region on an under surface
configured to be placed against the outer surface of the portable
electronic device. The under surface may for example be an internal
surface within a cavity of the cover that surrounds the portable
electronic device. Although the connector region may be placed
anywhere on the portable electronic device, the connector region
can be placed on the back side of the portable electronic device.
Alternatively, it may be placed on the bottom side of the portable
electronic device. The connector region may include one or more
exposed contact pads or pins configured in a variety of layouts and
shapes.
[0169] The various aspects, embodiments, implementations or
features of the invention can be used separately or in any
combination.
[0170] The advantages of the invention are numerous. Different
embodiments or implementations may, but need not, yield one or more
of the following advantages. One advantage of certain embodiments
of the invention is that a cover having one or more electronic
components embedded therein can serve to extend or augment
capabilities of a portable electronic device being covered by the
cover. For example, the one or more electrical components provided
in a cover can be used (i) to extend input/output capabilities of
the portable electronic device, (ii) to augment functional
capabilities of the portable electronic device; and/or (iii) to
associate ornamental aspects to the portable electronic device.
[0171] The many features and advantages of the present invention
are apparent from the written description. Further, since numerous
modifications and changes will readily occur to those skilled in
the art, the invention should not be limited to the exact
construction and operation as illustrated and described. Hence, all
suitable modifications and equivalents may be resorted to as
falling within the scope of the invention.
