Description
BACKGROUND
[0001] Electrochromic devices, in which optical transmissivity is
electrically controlled, are in current usage in building windows
and in dimmable automotive rearview mirrors. Generally,
electrochromic windows for a building are controlled with a driver
and a user input, e.g., a dimmer control. Electrochromic rearview
mirrors in automotive usage often have a light sensor aimed to
detect light from headlights of automobiles, and are user-settable
to engage an auto-dim function that adjusts the tint of the mirror
based on input from the light sensor. There is a need in the art
for a control system for electrochromic devices which goes beyond
such basic settings and functions.

DETAILED DESCRIPTION
[0023] A smart window system, disclosed herein, has a distributed
device network control system architecture that can distribute
control of optical transmissivity of smart windows across the smart
windows, intelligent window controller/drivers, a command and
communication device, and one or more resources on a network. A
smart window within such a system can be defined as a window with
some local and/or external or remote computer processing
capabilities and which is connectable to the internet. In some
embodiments the window is an electrochromic window but this is not
meant to be limiting as non-electrochromic windows may be smart
windows as described herein. Electrochromic and non-electrochromic
windows may be integrated into the same system in some embodiments.
The smart window may function as a glass partition in some
embodiments and be within an interior of a structure rather than
have one surface facing an exterior in some embodiments. The smart
window system combines input from sensors integrated with the smart
windows, user input, and information and direction from the network
to control the smart windows in an interactive, adaptive manner.
Control can shift from one component to another, be shared across
multiple components, or be overridden by one component of the
system, in various embodiments. The distributed nature of the
architecture and the control support various system behaviors and
capabilities. FIGS. 1-5 show various embodiments of a smart window
system and the distributed device network control system
architecture. FIGS. 6-13 illustrate a security focused system for
smart windows, with system behaviors and capabilities inclusive of
those described above but also featuring specialized behaviors and
capabilities dedicated to detecting and reacting to security
events. These embodiments have various mechanisms for detecting a
personal or property security threat such as an intrusion or an
intruder, a fire or smoke, carbon monoxide, chemical or other
hazardous air quality, etc., and for controlling transmissivity of
smart windows so as to prove advantageous to occupants or emergency
personnel.
[0024] FIG. 1 is a system diagram of a smart window system that has
a distributed device network control system architecture in
accordance with an embodiment of the present disclosure. The system
is both modular and distributed, and is suitable for installation
in various living, working or commercial spaces, such as an
apartment, house, an office, a building, a store, a mall, etc.
Modularity allows for replacement of individual components,
upgrades, expansion, linking of two or more systems, and
communication in the system and among multiple systems. Wireless
couplings, wired couplings, and combinations thereof are supported
by the smart window system. Although antennas 124 are shown for the
wireless coupling, further embodiments could use infrared
coupling.
[0025] Control is distributed across one or more first control
systems 114, with one in each smart window 102, one or more second
control systems 116, with one in each intelligent window
controller/driver 104, a third control system 118 in a command and
communication device 106, and a fourth control system 120 in a
server 108 coupled to a network 110. Each smart window 102 has an
antenna 124 and is thereby wirelessly connected to a nearby
intelligent window controller/driver 104, also with an antenna 124.
In further embodiments, a wired connection could be used. Each
intelligent window controller/driver 104 is wirelessly connected to
the command and communication device 106, which has an antenna 124.
In further embodiments, a wired connection could be used. The
command and communication device 106 is coupled to a network 110,
such as the global communication network known as the Internet.
This coupling could be made via a wireless router (e.g., in a home,
office, business or building), or a wired network connection. User
devices 136 (e.g., smart phones, computers, various computing
and/or communication devices) can couple to the command and
communication device 106, for example by a direct wireless
connection or via the network 110, or can couple to the server 108
via the network 110, as can other systems 138 and big data 112. In
some embodiments, the server 108 hosts an application programming
interface 140. The server 108 could be implemented in or include,
e.g., one or more physical servers, or one or more virtual servers
implemented with physical computing resources, or combinations
thereof.
[0026] Modularity of the system supports numerous layouts and
installations. For example, each windowed room in a building could
have one or more smart windows 102 and a single intelligent window
controller/driver 104 for that room. An intelligent window
controller/driver 104 could control smart windows 102 in part of a
room, an entire room, or multiple rooms. The intelligent window
controller/driver(s) 104 for that floor of the building, or for a
portion of or the entire building in some embodiments, could tie
into a single command and communication device 106, which is
coupled to the network 110 and thereby coupled to the server 108.
In a small installation, one or more smart windows 102 could couple
to a single intelligent window controller/driver 104 for local
distributed control, or a single command and communication device
106 for both local and network distributed control. Or, an
intelligent window controller/driver 104 could be combined with the
command and communication device 106, in a further embodiment for
small systems that use both local control and network information.
Large systems, e.g., for multiple occupant buildings, could have
multiple command and communication devices 106, e.g., one for each
occupant or set of occupants, or each floor or level in the
building, etc. Upgrades or expansions are readily accommodated by
the addition of further components according to the situation.
[0027] In one embodiment as shown in FIG. 1, the command and
communication device 106 has a wireless interface 128, a wired
interface 130, a control system 118, a rules engine 132, a network
interface 134, and a user I/O (input/output) module 142. The
wireless interface 128 and/or the wired interface 130 are used for
coupling to the intelligent window controller/driver(s) 104. The
network interface 134 is used for connecting to the network 110.
For example, the network interface 134 could connect to a wireless
router or Wi-Fi, e.g., via the wireless interface 128, or to a
wired network via the wired interface 130. In some embodiments, the
wireless interface 128 and/or the wired interface 130 can couple to
third-party devices for sensing, input and/or output (see, e.g.,
description regarding FIG. 3). The rules engine 132 uses
information from the network 110, which can include direction from
the fourth control system 120 in the server 108, and can include
information from user devices 136, other systems 138, or big data
112, to create, populate, modify, or adapt various rules for
operation of the smart windows 102. The user I/O module 142 accepts
user input, e.g., via buttons, a touchscreen, etc., and displays
user output, e.g., via a display screen or with LEDs or other
lamps, etc. Some embodiments may lack the user I/O module 142, or
have a user input module or an output module. In keeping with the
nature of this distributed control system, the third control system
118 of the command and communication device 106 can direct
operation of the smart windows 102, the second control system 116
of the intelligent window controller/driver(s) 104 can direct
operation of the smart windows 102, the fourth control system 120
of the server 108 can direct operation of the smart windows 102,
and/or the first control system 114 of each smart window 102 can
direct operation of that smart window 102, in various combinations.
Some embodiments have a failover mechanism, in which control and/or
communication are routed around a failed device in the system.
[0028] As shown by the dashed lines, communication can proceed
amongst various members of the smart window system over various
paths, in various embodiments. In some embodiments, a message or
other communication is passed along a chain, such as from a smart
window 102, to an intelligent window controller/driver 104, or via
the intelligent window controller/driver 104 to the command and
communication device 106, and vice versa. In some embodiments, a
device can be bypassed, either by direct communication between two
devices or by a device acting as a relay. For example, a smart
window 102 could communicate directly with a command and
communication device 124 wirelessly via the wireless interface 128
or via the wired interface 130. Or, an intelligent window
controller/driver 104 could relay a message or other communication,
as could the command and communication device 106. In some
embodiments, messages or communications can be addressed to any
component or device in the system, or broadcast to multiple
devices, etc. This could be accomplished using packets for
communication, and in some embodiments any of the control systems
114, 116, 118, 120 can communicate with the cloud, e.g., the
network 110.
[0029] FIG. 2 is a system diagram of a smart window 102 that has an
electrochromic window 204 and a window frame 202 with an embedded
module 206. The embedded module 206 could be positioned at the
bottom, top, to one or both sides, or distributed around the window
frame 202 in various embodiments. The embedded module 202 has one
or more sensors 212, which could include temperature, light,
audio/acoustic (i.e., sound), vibration, video or still image,
motion, smoke detection, chemical, humidity or other sensors, and
which could be facing inwards, i.e., into a room, or outwards,
i.e., to the exterior of the room or building, in various
embodiments. The wireless interface 128 has an antenna 124, which
is used for coupling to the intelligent window controller/driver(s)
104, the command and communication device 106, and/or one or more
user devices 136 (e.g., a smart phone, a user wearable device,
etc.). A wired interface 130 could also be included, or could be
used in place of a wireless interface 128. The control system 114,
shown as the first control system 114 in FIG. 1, provides local
control for the electrochromic window 204 via the voltage or
current driver 208. Alternatively, the control system 114
participates in distributed control. Some embodiments have a rules
engine 132 in the module 206. The voltage or current driver 208
sends voltage or current to bus bars of the electrochromic window
204, as directed by one or more of the control systems 114, 116,
118, 120, to control transmissivity of the electrochromic window
204. In some embodiments, to change transmissivity of the
electrochromic window 204, the voltage or current driver 208
provides constant current until a sense voltage of the
electrochromic window 204 is reached. Then, the voltage or current
driver 208 provides a current that maintains the sense voltage at a
constant voltage, until a total amount of charge is transferred to
the electrochromic window 204 for the new transmissivity level. The
embedded module 206 also includes an input device 214, or a user
I/O module 142, through which user input can be entered at the
smart window 102. In some embodiments, user input can also be
entered through the wireless interface 128, e.g., from a smart
phone.
[0030] FIG. 3 is a system diagram of an intelligent window
controller/driver 104, from the smart window system of FIG. 1. The
intelligent window controller/driver 104 includes a wireless
interface 128 with an antenna 124, a wired interface 130, a user
I/O module 142, and a control system 116, which is shown as the
second control system 116 in FIG. 1. Some embodiments have a rules
engine 132. The wireless interface 128 couples to one or more smart
windows 102 via the wireless interface 128, as shown in FIG. 1,
although the wired interface 130 could be used in further
embodiments. Either the wireless interface 128 or the wired
interface 130 can be used to couple to the command and
communication device 106, in various embodiments. In some
embodiments, the wireless interface 128 and/or the wired interface
130 can couple to further devices, such as third-party devices for
input information, sensing or control output. For example, the
system could control or interact with lighting controllers, HVAC
(heating, ventilation and air-conditioning, e.g., by coupling to a
thermostat), burglar and/or fire alarm systems, sound system,
desktop, smart phones, or other systems or devices, or receive
further input from further sensors, cameras, etc. It should be
appreciated that the wireless interface 128 and/or the wired
interface 130 may accommodate voice commands through I/O module 142
or some other input device. In some embodiments, non-control output
and information exchange can be completed with a third party device
for analytical purposes. The user I/O module 142 could include
buttons, a touchpad, a touchscreen, a display screen, etc., for
user input to the system and/or output from the system. The second
control system 116 participates in distributed control with the
first control system 114 of the smart window 102, or can override
the first control system 114. In some embodiments, the second
control system 116 relays direction from the third control system
118 of the command and communication device, or the fourth control
system 120 of the server 108, to one or more smart windows 102. It
should be appreciated that the location of the intelligent window
controller/driver 104 may be integrated with the window or wall
mounted proximate to a window or windows. In addition, the
intelligent window controller/driver 104 may be utilized to control
other home systems, such as lights, home entertainment systems,
etc.
[0031] FIG. 4 is a system diagram of a command and communication
device 106, from the smart window system of FIG. 1. Since the
command and communication device 106 is coupled to the network 110,
in some embodiments the command and communication device 106 has
various protections against unauthorized access. Here, the command
and communication device 106 has a firewall 104, a malware
protection engine 408, an authentication engine 402, and a
certificate repository 406. The firewall 104 is applied in a
conventional manner, to communications arriving via the wired
interface 130 or the wireless interface 128 (see FIG. 1).
[0032] The authentication engine 402 can be applied to authenticate
any component that is coupled to or desires to couple to the
command and communication device 106. For example, each smart
window 102 could be authenticated, each intelligent window
controller/driver 104 could be authenticated, and the server 108
could be authenticated, as could any user device 136 or other
system 138 attempting to access the smart window system. The
command and communication device 106 can authenticate itself, for
example to the server 108. To do so, the command and communication
device 106 uses a certificate from the certificate repository 406
for an authentication process (e.g., a "handshake") applied by the
authentication engine 402.
[0033] The malware protection engine 408 can look for malware in
any of the communications received by the commanded communication
device 106, and block, delete, isolate or otherwise handle
suspected malware in a manner similar to how this is done on
personal computers, smart phones and the like. Updates, e.g.,
malware signatures, improved malware detection algorithms, etc.,
are transferred to the malware protection engine 408 via the
network 110, e.g., from the server 108 or one of the other systems
138 such as a malware protection service.
[0034] FIG. 5 is a block diagram showing aspects of the distributed
device network control system architecture of FIG. 1. Although this
architecture lends itself to hierarchical control, which can be
performed by overrides or blocking from components higher up in the
chain, or by weighting inputs, votes, or commands, it should be
appreciated that control is generally distributed across and
movable among the first control system(s) 114, the second control
system(s) 116, the third control system 118 and the fourth control
system 120, i.e., distributed across and movable among the server
108, the command and communication device 106, the intelligent
window controller/drivers 104, and the smart windows 102. Smart
windows 102 can be operated individually, or in various groups
(e.g., facing in a particular direction, installed at a common
location (height or wall area) or associated with a particular room
or group of rooms, or level or floor of a house or other building,
subsets or groupings of windows, and so on) using this distributed
control architecture. Generally, each control system 114, 116, 118,
120 controls or directs one or more of the smart windows 102, in
cooperation with other members of the system. Each control system
114, 116, 118, 120 has respective rules, e.g., the first control
system 114 has first rules 502, the second control system has
second rules 504, the third control system 118 has third rules 506,
the fourth control system 120 has fourth rules 508. Each control
system 114, 116, 118, 120 operates according to its local rules,
which may incorporate rules distributed from other devices, unless
overridden by another device in the system. Rules can include
cooperation with other devices, and rules can include instructions
allowing for when an override is permissible. For example, an
intelligent window controller/driver 104 could override a smart
window 102, the command and communication device 106 could override
an intelligent window controller/driver 104 or a smart window 102,
the server 108 could override the command and communication device
106, an intelligent window controller/driver 104, or a smart window
102, or user input at one of the devices or from a user device 136
or software or application resident on the device could override
one or more of these. Information from the sensors 212 of the smart
window(s) 102 enters the system through the first control system(s)
114, and can be routed or directed to any of the further control
systems 116, 118, 120. Information 510 from the network enters the
system through the fourth control system 120, i.e., the server 108,
and/or the third control system 118, i.e., the command and
communication device 106, and can be routed or directed to any of
the further control systems 114, 116. User input can enter the
system through the smart windows 102, e.g., through user input at
that smart window 102 or wireless user input from a user device 136
to the smart window 102. User input can also enter the system
through the intelligent window controller/driver(s) 104, e.g.,
through user input at the intelligent window controller/driver 104
or wireless user input from a user device 136. User input can enter
the system through the third control system 118, e.g., through a
wireless coupling from a user device 136 or via the network
connection, e.g., from a user device 136. User input can enter the
system through the fourth control system 120, e.g., via the server
108. From any of these entry points, the user input can be routed
to any of the control systems 114, 116, 118, 120. Each of the
control systems 114, 116, 118, 120 can communicate with each other
control system 114, 116, 118, 120, and can update respective rules
502, 504, 506, 508 as self-directed or directed by another one or
combination of the control systems 114, 116, 118, 120. Control can
be cooperative, voted, directed, co-opted, overridden, local,
distributed, hierarchical, advisory, absolute, and so on, in
various combinations at various times during operation of the
system, in various embodiments. It should be appreciated that user
inputs can include pre-programmed rules, agent-programmed rules,
user programmed rules, and artificial intelligence that acts based
on rules or makes statistical or analytical based decisions.
[0035] In some embodiments, the smart window system operates the
smart windows 102 in a continuous manner, even if there is a
network 110 outage (e.g., there is a network outage outside of the
building, a server is down, or a wireless router for the building
is turned off or fails, etc.). The first control system 114, the
second control system 116 and/or the third control system 118 can
direct the smart windows 102 without information from the network,
under such circumstances. In various combinations, each of the
control systems 114, 116, 118, 120 can create, store, share and/or
distribute time-bound instructions (e.g., instructions with goals
to perform a particular action at or by a particular time), and
these time-bound instructions provide continuity of operation even
when one or more devices, or a network, has a failure. When the
network 110 is available, the third control system 118 obtains
weather information from the network, either directly at the third
control system 118 or with assistance from the server 108. For
example, the third control system 118 could include and apply
cloud-based adaptive algorithms. With these, the third control
system 118 can then direct operation of the smart windows 102 based
on the weather information. One or a combination of the control
systems 114, 116, 118, 120 can direct operation of the smart
windows 102 based on sensor information, such as from light, image,
sound or temperature sensors of the smart windows 102. For example,
if the weather information indicates cloud cover, or sensors 212
are picking up lowered light levels, the system could direct an
increase in transmissivity of the smart windows 102, to let more
natural light in to the building. If the weather information
indicates bright sun, or sensors 212 are picking up increased or
high light levels, the system could direct a decrease in
transmissivity of the smart windows 102, to decrease the amount of
natural light let in to the building. The system can modify such
direction according to orientation of each window, so that windows
pointing away from the incidence of sunlight are directed
differently than windows pointing towards incidence of sunlight. If
weather information indicates sunlight, and temperature sensors
indicate low temperatures, the system could direct increased
transmissivity of the smart windows 102, in order to let in more
natural light and increase heating of a building interior
naturally. Or, if the temperatures sensors indicate high
temperatures, the system could direct decreased transmissivity of
the smart windows 102, to block natural light and thereby hold down
the heating of the interior of the building by sunlight.
[0036] FIG. 6 is a system action diagram showing actions 614 of a
security focused system for smart windows 102, in an embodiment of
the smart window system of FIG. 1. Emphasis in embodiments of the
security focused system is on detecting security events, such as a
break-in, an intruder, a fire, etc. One or more sensors 212 in the
distributed device network 602 (see depictions in FIGS. 1 and 5,
and variations thereof) provide sensor data which the system can
use to detect a security event, and then take action 614 and/or
send alerts 626. In some embodiments, the action 614 may be
triggered by a third party device, user or cloud signal.
Distributed sensors 212 are embedded in the smart window system,
specifically as embedded in smart windows 102 (see FIG. 2) and/or
coupled to intelligent window controller/drivers 104 (see FIG. 1)
in the distributed device network 602. The sensors 212 thus form
one or more smart window perimeters and a window sensor network,
which becomes the distributed intelligence of a building security
system.
[0037] Sensors 212 in the system could include temperature sensors
602, cameras 604, audio sensors 606, carbon dioxide sensors 608,
carbon monoxide sensors 610, smoke sensors 612, chemical or
hazardous air quality sensors and so on, in various forms and
combinations. Embodiments of sensors embedded in smart windows 102
are further described with reference to FIGS. 7 and 8, and
scenarios in which the sensors 212 are used to detect security
events are further described with reference to FIGS. 9 and 10.
[0038] Actions 614 that the security focused system could perform,
in various combinations, in response to a security event include an
action 616 to set maximum transmissivity for smart windows (or
increased transmissivity, as a variation), an action 618 to light
path lights, an action 620 to self-break one or more windows, an
action 622 to blink lights, or an action 624 to turn off or dim
lights. The above actions are described with reference to FIGS.
11A-12. Further actions, 614 such as opening/closing and
lock/unlock windows are readily devised in keeping with the
teachings herein.
[0039] Alerts 626 that the security focused system could send, in
various combinations, in response to a security event include a
burglar or intruder alert 628, a smoke alert 630, a fire alert 632,
or an email 634. The system could send a text message to a user
device 136, an audio message, a fax message, a video message (e.g.,
live streaming from one or more cameras 604, or recorded video),
etc. In some embodiments, a user device 136 receiving an alert 626
could then select a camera 604 or an audio sensor 606 and receive a
live or recorded stream from that device, or a mosaic of images or
other presentation of still images, video or audio, on the user
device 136 for monitoring. The user would then have the option of
contacting authorities or a neighbor, etc. In some embodiments,
such a live or recorded stream or other presentation could be
directed to or archived in the server 108 (see FIG. 1), which could
aid in criminal prosecution or insurance recovery, etc.
[0040] FIG. 7 is a system diagram of an embodiment of a smart
window 102 with various sensors 212 suitable for the security
focused system of FIG. 6. In various embodiments, each smart window
102 could have one or more of these or other sensors 212. In some
embodiments, some smart windows 102 have some sensors 212, other
smart windows 102 have differing sensors 212, and all smart windows
102 do not necessarily have the same sensors 212. Some embodiments
have one or more sensors 212 embedded in a frame of the smart
window 102. A thermocouple or other temperature sensing device
could be employed as a temperature sensor 602. A video camera, a
still camera or other image capturing device could be used as a
camera 604, which could have various lenses and/or mirrors. There
could be more than one camera 604. An acoustic or vibration sensor
702 could be used as an audio sensor 606. For example, a
piezoelectric device in the vicinity of or contacting the
electrochromic window 204 can serve to detect vibration of the
electrochromic window 204, and may act as a microphone with the
electrochromic window 204 as a diaphragm in some embodiments. Or, a
vibration transducer, with a separate diaphragm, or with the
electrochromic window 204 as a diaphragm, could be used. A
microphone 704 could be used as an audio sensor 606. Various
gas/chemical detection sensors, such as the carbon monoxide sensor
610 and the carbon dioxide sensor 608 can be used for detecting
elevated levels of selected gases as associated with a fire. There
are various types of smoke detectors and sensors 612, e.g., optical
detectors, particulate detectors, and one or more of these could be
used as a sensor 212.
[0041] Some embodiments of the smart window 102 have a window
self-break module 706. This is used to break the electrochromic
window 204, as a response to a security event. For example, a
mechanism similar to an automotive airbag deployment module, with
an electrically triggered chemical reaction, could be used, as
could a small explosive charge. Alternatively, an electrically
heated resistive element could crack the electrochromic window 204.
In embodiments with double pane glass or plastic or the
electrochromic window 204, such a chemical reaction device or small
explosive charge could be placed in the sealed interior of the
electrochromic window 204, between the two panes, and energized to
"blow the hatch". This could allow a person to escape a fire, by
climbing out a window. Or, it could distract an intruder, in a home
invasion event. In case of a fire it may be beneficial to actively
close all windows mechanically and unlock the windows. The breaking
of the window may be triggered by a knock on the window when a fire
is detected in some embodiments.
[0042] FIG. 8 is a diagram of a variation of the smart window 102
of FIG. 7. Here, the camera 604 embedded in the smart window 102
has an outward facing camera view 802 (e.g., facing to the exterior
of the room or building) and/or an inward facing camera view 804
(e.g., facing to the interior of the room or building). This can be
accomplished with one camera appropriately mounted, two cameras,
one facing inward, one facing outward, one camera with mirrors and
a split view, wide or ultra-wide-angle lenses, compound lenses,
etc. The outward facing camera view 802 could be useful in
detecting a possible intruder approaching a smart window 102, for
example with the intent of observing a potential target or breaking
in. The inward facing camera view 804 could be useful in detecting
an intruder or occupant in the interior of a room or building. In
related matters, other sensors 212 could be mounted outward facing
or inward facing.
[0043] FIG. 9 is a scenario diagram showing the security focused
system for smart windows 102 detecting an intruder 902. Various
embodiments employ a single mechanism or multiple mechanisms to
detect an intrusion or an intruder 902. One mechanism is broken
glass detection 906, in which an acoustic/vibration sensor 702, or
a microphone 704 or other audio sensor 606 detects the sound or
vibration of glass breaking, as could occur if a burglar or other
intruder 902 breaks a window to get in to a house or other
building. Alternatively, the system could detect that operation of
an electrochromic window 204 has suddenly changed, for example the
electrochromic window 204 no longer sustains a constant or varied
current during transmissivity changes, has a very different (e.g.,
out of a normal or expected) voltage reading across sense terminals
or bus bars, or the electrochromic window 204 has a sudden change
in measured resistance, etc.
[0044] One mechanism for intruder detection 902 is video detection.
The outward facing camera view 802 could be used to detect a
possible intruder 902 exterior to the room or building, and this
could be compared with an inward facing camera view 804 to see if
the possible intruder 902 has become an actual intruder 902 in the
interior of the room or building. The system could be set to an
"away" mode, in which detection of any moving, human-sized object
in the interior of a room or building is indicative of an intruder
902. Audio sensors 606 could be similarly employed. The system can
then relay sensor information from the smart windows 102 to the
intelligent window controller/driver 104, and thence to the command
and communication device 106. Since the system has distributed
processing and intelligence, analysis of video information, audio
information, or other sensor information can take place at one or
more of the smart windows 102, the intelligent window
controller/driver(s) 104 and/or the command and communication
device 106, in various combinations and embodiments. For example,
there could be distributed processing of such information, with
each component performing part of the analysis, or components could
relay raw information and the command and communication device 106
could perform the heavyweight analysis, etc. As an example suitable
for the scenario depicted in FIG. 9, one smart window 102 could
perform broken glass detection 906, another smart window 102 could
perform video or audio verification of presence of an intruder 902,
and the intelligent window controller/driver 104 and/or the command
and communication device 106 could track movement of the intruder
902 and issue one or more alerts 626 or perform one or more actions
614. The command and communication device 106 could send alerts to
a monitor service 906 (e.g., an alarm monitoring service that has
authorization to dispatch fire, police or other emergency
personnel), the user device 136, and/or an authorized secondary
user device 136 (e.g., that of a neighbor, relative or other
trusted person). Intruders 902 have various entry strategies, and
various algorithms are readily developed to address these
strategies and implemented in accordance with embodiments described
herein.
[0045] FIG. 10 is a scenario diagram showing the security focused
system for smart windows 102 detecting a fire 1002. One or more
sensors 212 of one or more smart windows 102 detect a fire 1002
and/or smoke 1012. Sensor information is relayed from the smart
window(s) 102 to the intelligent window controller/driver(s) 104
and the command and communication device 106. For example, fire
could be detected by a temperature sensor 602, a camera 604, a
light sensor, or an audio sensor 606 (e.g., listening for the
crackle of a fire or falling timbers). Smoke could be detected by a
smoke detector/sensor 612, elevated levels of carbon dioxide could
be sensed by a carbon dioxide sensor 608, or elevated levels of
carbon monoxide could be sensed by a carbon monoxide sensor 610.
Processing of sensor information could be performed in various
components or in a distributed manner as described above with
reference to intruder detection in FIG. 9. The command and
communication device 106 sends alerts 626 to a monitor service 906,
a user device 136 and/or an authorized secondary user device
136.
[0046] In some embodiments, the command and communication device
106, or in further embodiments the intelligent window
controller/driver(s) 104, couples to and communicates with a
heating ventilation or air conditioning unit (HVAC) 1004 and/or a
lighting controller 1006. For example, the command and
communication device 106 is shown with a wired connection to the
heating, ventilation or air conditioning unit 1004, although in
further embodiments a wireless connection could be used. The
intelligent window controller/driver 104 is shown with a wired
connection to a lighting controller 1006, although in further
embodiments a wireless connection could be used. Or, a lighting
controller 1006 could be integrated into an intelligent window
controller/driver 104 or the command and communication device 106.
In case of a fire 1002, and in response to detecting this as a
security event, the command and communication device 106 directs
the heating, ventilation or air conditioning unit 1004 to turn off
all fans in order to prevent smoke 1012 or fire 1002 from
spreading. The command and communication device 106 could direct
the intelligent window controller/driver 104, or the intelligent
window controller/driver 140 could decide, to operate lighting in
various ways when so coupled to a lighting controller 1006. The
intelligent window controller/driver 104 could direct the lighting
controller 1006 to turn on emergency lighting 1010, turn on other
lights 1008, or flash some or all of the lights 1008, or operate
lighting in various further ways.
[0047] FIG. 11A depicts the security focused system for smart
windows 102 directing maximum optical transmissivity of the smart
windows 102, and turning on the lights 1008, as a response to a
security event. The smart windows 102 are shown transitioning from
various optical states of transmissivity to maximum transmissivity
(or, increased transmissivity) at the direction of the intelligent
window controller/driver 104. The intelligent window
controller/driver 104 is also coupled to the lighting controller
1006, and directs the lighting controller 1006 to turn on the
lights 1008, or flash the lights 1008, etc. This response to a
security event could be useful to show responding personnel the
condition of the interior of the house or other building in an
emergency. For example, in case of a fire, the firefighters can see
in through the increased or maximum transmissivity smart windows
102, to a well-lit interior, and perform rescue duties as
appropriate. In case of an intruder 902, responding police
personnel can see in through the increased or maximum
transmissivity smart windows 102, to a well-lit interior, and see
the intruder 902. In variations, if the system detects a fire or an
intruder 902 in one room, or detects a fire anywhere in the house
and presence of a person in one room, the system could direct the
lighting controller 1006 to flash the lights 1008 in that room to
draw attention to that situation. Further variations of this
scenario and the response to the security event are readily devised
and implemented in embodiments of the smart window system.
[0048] FIG. 11B depicts the security focused system for smart
windows 102 directing the smart windows 102 to cycle
transmissivity, as a response to a security event. A single smart
window 102 is shown cycling from maximum transmissivity (at far
left) to minimum transmissivity (at second to the left) and back to
maximum transmissivity (in the middle), etc. In variations, reduced
or increased transmissivity settings could be used. Transmissivity
cycling could be used as an external indicator with or without
flashing lights 1008 as described above with reference to FIG.
11A.
[0049] FIG. 11C depicts the security focused system for smart
windows 102 directing minimum optical transmissivity of the smart
windows 102, as a nighttime or privacy tint function. A group of
smart windows 102 is shown transitioning from various states of
transmissivity to minimum transmissivity. Alternatively, reduced
transmissivity could be used. The nighttime or privacy tint
function could be used in a scheme or profile, set to a specific
time of day, or varied according to seasonal daylight variation, or
activated in response to user input. The system would then override
this setting in response to detecting a security event, as
described above.
[0050] FIG. 12 depicts the security focused system for smart
windows 102 directing lights off and minimum transmissivity of all
smart windows 102 in a specified "safe room" 1202, and directing
all other lights on and maximum transmissivity of all other smart
windows 102 elsewhere in the system, as a response to a security
event. This is applicable to a hot prowl or home invasion scenario,
in which the system detects an intruder 902 while other people may
be present. The smart window system performs intruder detection as
described above (see FIG. 9), and then in response directs a
nighttime or privacy tint function (see FIG. 11C) for the selected
smart windows 102 as configured for the safe room 1202. The smart
window system also directs a lighting controller 1006 (see FIG. 10)
to turn off lights in the designated safe room 1202. Meanwhile, the
smart window system directs maximum transmissivity (see FIG. 11A)
of smart windows 102 other than the smart windows 102 of the
designated safe room 1202, and directs either the same lighting
controller 1006 or a further lighting controller 1006 to turn on
lights 1008 other than any lights 1008 of the designated safe room
1202. This allows people to hide in a darkened safe room 1202,
while the other rooms are highlighted internally and externally by
lighting and maximum transmissivity smart windows 102 so that
responding police or security personnel can more readily identify
and apprehend an intruder 902. In a further embodiment, the system
could activate a lock for the safe room 1202, or activate other
security measures.
[0051] FIG. 13 is a flow diagram of a method of operating a smart
window-based security system, which can be practiced on or using
embodiments of the smart window system. The method can be practiced
by one or more processors of the smart window system. Variations of
the method, with fewer actions, more actions, differing sequences
for actions, and/or actions dependent upon conditions such as
whether the security event is a fire or an intruder detection,
etc., are readily devised in keeping with the teachings herein.
[0052] In an action 1302, sensor information is obtained from
sensors of a smart window system. Embodiments of the distributed
device network, as described herein, have a distributed sensor
network defining a security perimeter, and are suitable for
gathering the sensor information. In an action 1304, the sensor
information is analyzed. Analysis can take place in one or more
components, or be distributed across multiple components of a smart
window system. Transmissivity of smart windows is controlled, in an
action 1306. The transmissivity settings, and operation of the
system can be based on user input, the sensor information, and/or
cloud-based learning. In a decision action 1308, it is determined
whether a security event is detected. This determination is based
on the analysis of the sensor information. If there is no security
event detected, flow branches back to the action 1302, in order to
obtain further sensor information, continue analysis of sensor
information, and continue controlling transmissivity of the smart
windows. If there is a security event detected, flow proceeds to
the action 1310.
[0053] In the action 1310, transmissivity of first smart windows is
increased. The transmissivity could be set to a maximum. This
direction comes from the smart window system, and could be absolute
or conditional depending upon what type of security event is
detected. Selection of which smart windows are in which group of
smart windows should be made, for example, during set up or
installation, or at a later time but prior to the detection of a
security event. In an action 1312, transmissivity of second smart
windows is decreased. The transmissivity could be set to a minimum.
This direction comes from the smart window system, and could be
absolute or conditional depending upon what type of security event
is detected. For example, selection of which smart windows are in
the group of second windows could be in accordance with selection
or designation of a safe room, and direction to decrease the
transmissivity of these smart windows could be conditioned upon
detection of an intruder or break-in. In an action 1314,
transmissivity of third smart windows is cycled. This direction
comes from the smart window system, and could be absolute or
conditional depending upon what type of security event is detected.
For example, smart windows in a room that has a fire, or has a
person present, could be cycled to highlight this situation.
[0054] In an action 1316, first lights are turned on. In an action
1318, second lights are turned off. In an action 1320, third lights
are flashed. This direction relies on the smart window system
coupling to or integrating a lighting controller, and could be
conditional depending on what type of security event is detected,
or applied in various combinations to various groups of lights. In
an action 1322, one or more alerts are sent. These could be sent
via the network to which the smart window system is coupled, and
could go out to a monitor service, or one or more of several user
devices, etc. It should be appreciated that the alert may be sent
at any point in the method upon determination of a security event
being detected.
[0055] It should be appreciated that the methods described herein
may be performed with a digital processing system, such as a
conventional, general-purpose computer system. Special purpose
computers, which are designed or programmed to perform only one
function may be used in the alternative. FIG. 14 is an illustration
showing an exemplary computing device which may implement the
embodiments described herein. The computing device of FIG. 14 may
be used to perform embodiments of the functionality for the
security focused system for smart windows in accordance with some
embodiments. The computing device includes a central processing
unit (CPU) 1401, which is coupled through a bus 1405 to a memory
1403, and mass storage device 1407. Mass storage device 1407
represents a persistent data storage device such as a floppy disc
drive or a fixed disc drive, which may be local or remote in some
embodiments. Memory 1403 may include read only memory, random
access memory, etc. Applications resident on the computing device
may be stored on or accessed via a computer readable medium such as
memory 1403 or mass storage device 1407 in some embodiments.
Applications may also be in the form of modulated electronic
signals modulated accessed via a network modem or other network
interface of the computing device. It should be appreciated that
CPU 1401 may be embodied in a general-purpose processor, a special
purpose processor, or a specially programmed logic device in some
embodiments.
[0056] Display 1411 is in communication with CPU 1401, memory 1403,
and mass storage device 1407, through bus 1405. Display 1411 is
configured to display any visualization tools or reports associated
with the system described herein. Input/output device 1409 is
coupled to bus 1405 in order to communicate information in command
selections to CPU 1401. It should be appreciated that data to and
from external devices may be communicated through the input/output
device 1409. CPU 1401 can be defined to execute the functionality
described herein to enable the functionality described with
reference to FIGS. 1-13. The code embodying this functionality may
be stored within memory 1403 or mass storage device 1407 for
execution by a processor such as CPU 1401 in some embodiments. The
operating system on the computing device may be MS DOS.TM.,
MS-WINDOWS.TM., OS/2.TM., UNIX.TM., LINUX.TM., or other known
operating systems. It should be appreciated that the embodiments
described herein may also be integrated with a virtualized
computing system that is implemented with physical computing
resources.
[0057] Detailed illustrative embodiments are disclosed herein.
However, specific functional details disclosed herein are merely
representative for purposes of describing embodiments. Embodiments
may, however, be embodied in many alternate forms and should not be
construed as limited to only the embodiments set forth herein.
[0058] It should be understood that although the terms first,
second, etc. may be used herein to describe various steps or
calculations, these steps or calculations should not be limited by
these terms. These terms are only used to distinguish one step or
calculation from another. For example, a first calculation could be
termed a second calculation, and, similarly, a second step could be
termed a first step, without departing from the scope of this
disclosure. As used herein, the term "and/or" and the "/" symbol
includes any and all combinations of one or more of the associated
listed items.
[0059] As used herein, the singular forms "a", "an" and "the" are
intended to include the plural forms as well, unless the context
clearly indicates otherwise. It will be further understood that the
terms "comprises", "comprising", "includes", and/or "including",
when used herein, specify the presence of stated features,
integers, steps, operations, elements, and/or components, but do
not preclude the presence or addition of one or more other
features, integers, steps, operations, elements, components, and/or
groups thereof. Therefore, the terminology used herein is for the
purpose of describing particular embodiments only and is not
intended to be limiting.
[0060] It should also be noted that in some alternative
implementations, the functions/acts noted may occur out of the
order noted in the figures. For example, two figures shown in
succession may in fact be executed substantially concurrently or
may sometimes be executed in the reverse order, depending upon the
functionality/acts involved.
[0061] With the above embodiments in mind, it should be understood
that the embodiments might employ various computer-implemented
operations involving data stored in computer systems. These
operations are those requiring physical manipulation of physical
quantities. Usually, though not necessarily, these quantities take
the form of electrical or magnetic signals capable of being stored,
transferred, combined, compared, and otherwise manipulated.
Further, the manipulations performed are often referred to in
terms, such as producing, identifying, determining, or comparing.
Any of the operations described herein that form part of the
embodiments are useful machine operations. The embodiments also
relate to a device or an apparatus for performing these operations.
The apparatus can be specially constructed for the required
purpose, or the apparatus can be a general-purpose computer
selectively activated or configured by a computer program stored in
the computer. In particular, various general-purpose machines can
be used with computer programs written in accordance with the
teachings herein, or it may be more convenient to construct a more
specialized apparatus to perform the required operations.
[0062] A module, an application, a layer, an agent or other
method-operable entity could be implemented as hardware, firmware,
or a processor executing software, or combinations thereof. It
should be appreciated that, where a software-based embodiment is
disclosed herein, the software can be embodied in a physical
machine such as a controller. For example, a controller could
include a first module and a second module. A controller could be
configured to perform various actions, e.g., of a method, an
application, a layer or an agent.
[0063] The embodiments can also be embodied as computer readable
code on a tangible non-transitory computer readable medium. The
computer readable medium is any data storage device that can store
data, which can be thereafter read by a computer system. Examples
of the computer readable medium include hard drives, network
attached storage (NAS), read-only memory, random-access memory,
CD-ROMs, CD-Rs, CD-RWs, magnetic tapes, and other optical and
non-optical data storage devices. The computer readable medium can
also be distributed over a network coupled computer system so that
the computer readable code is stored and executed in a distributed
fashion. Embodiments described herein may be practiced with various
computer system configurations including hand-held devices,
tablets, microprocessor systems, microprocessor-based or
programmable consumer electronics, minicomputers, mainframe
computers and the like. The embodiments can also be practiced in
distributed computing environments where tasks are performed by
remote processing devices that are linked through a wire-based or
wireless network.
[0064] Although the method operations were described in a specific
order, it should be understood that other operations may be
performed in between described operations, described operations may
be adjusted so that they occur at slightly different times or the
described operations may be distributed in a system which allows
the occurrence of the processing operations at various intervals
associated with the processing.
[0065] In various embodiments, one or more portions of the methods
and mechanisms described herein may form part of a cloud-computing
environment. In such embodiments, resources may be provided over
the Internet as services according to one or more various models.
Such models may include Infrastructure as a Service (IaaS),
Platform as a Service (PaaS), and Software as a Service (SaaS). In
IaaS, computer infrastructure is delivered as a service. In such a
case, the computing equipment is generally owned and operated by
the service provider. In the PaaS model, software tools and
underlying equipment used by developers to develop software
solutions may be provided as a service and hosted by the service
provider. SaaS typically includes a service provider licensing
software as a service on demand. The service provider may host the
software, or may deploy the software to a customer for a given
period of time. Numerous combinations of the above models are
possible and are contemplated.
[0066] Various units, circuits, or other components may be
described or claimed as "configured to" perform a task or tasks. In
such contexts, the phrase "configured to" is used to connote
structure by indicating that the units/circuits/components include
structure (e.g., circuitry) that performs the task or tasks during
operation. As such, the unit/circuit/component can be said to be
configured to perform the task even when the specified
unit/circuit/component is not currently operational (e.g., is not
on). The units/circuits/components used with the "configured to"
language include hardware--for example, circuits, memory storing
program instructions executable to implement the operation, etc.
Reciting that a unit/circuit/component is "configured to" perform
one or more tasks is expressly intended not to invoke 35 U.S.C.
112, sixth paragraph, for that unit/circuit/component.
Additionally, "configured to" can include generic structure (e.g.,
generic circuitry) that is manipulated by software and/or firmware
(e.g., an FPGA or a general-purpose processor executing software)
to operate in manner that is capable of performing the task(s) at
issue. "Configured to" may also include adapting a manufacturing
process (e.g., a semiconductor fabrication facility) to fabricate
devices (e.g., integrated circuits) that are adapted to implement
or perform one or more tasks.
[0067] The foregoing description, for the purpose of explanation,
has been described with reference to specific embodiments. However,
the illustrative discussions above are not intended to be
exhaustive or to limit the invention to the precise forms
disclosed. Many modifications and variations are possible in view
of the above teachings. The embodiments were chosen and described
in order to best explain the principles of the embodiments and its
practical applications, to thereby enable others skilled in the art
to best utilize the embodiments and various modifications as may be
suited to the particular use contemplated. Accordingly, the present
embodiments are to be considered as illustrative and not
restrictive, and the invention is not to be limited to the details
given herein, but may be modified within the scope and equivalents
of the appended claims.
