DETAILED DESCRIPTION OF THE INVENTION
The present invention generally relates to systems, methods, and program products for networked devices and home automation. Networked devices may be powered through lighting fixtures. The devices may be accessed and/or controlled through a data network, such as a local area network or the Internet and/or through direct connections, such as Bluetooth or other wireless communication protocols, which may provide an expandable and/or adaptable home automation system. Accordingly, the system enables remote access and/or control of networked devices. Moreover, such a networked device system can provide programmable control of one or more networked devices, which programming may be implemented and/or modified from a plurality of sources (e.g., a smart phone via a downloadable application, a computer or other user device accessing a website, a central server that implements general, default, and/or updated (e.g., seasonally updated) programming rules, a dedicated control device (such as a remote control panel), a wall-mountable control unit, and/or a device that performs other functions, such as a clock, alarm clock, and/or digital photo frame, that also includes networked device controls, to name a few). Such a system can be provided in accordance with the present invention without the need for wiring or re-wiring devices such as lights, speakers, cameras, and switches. Such a system may provide users with a high degree of system flexibility and reconfigurability since wiring is not required and reprogramming can be performed from user devices.
The networked device system can provide a lighting system, security system (e.g., comprising one or more cameras and/or motion detectors), climate control system (e.g., comprising climate and/or environmental sensors and/or controls), stereo system (e.g., comprising one or more speakers), video game and/or entertainment system (e.g., featuring any of ambient lighting, surround sound, motion detectors for body movement video game control inputs, other intelligent gesture control based on input gestures, and/or multi-projector system for 3-dimensional projections, to name a few), and/or network access points (e.g., Wi-Fi routers, Wi-Fi or other signal repeaters, mesh network relay nodes), to name a few. The networked device system can also interact with third-party devices, via garage door controls, automatic door locks, refrigerator or other appliance controls, and/or thermostats. In embodiments, a networked device may be adapted for connection to a socket for a light bulb, even where the device is not a lighting device or where the device functions as a light source as an ancillary function, e.g., where the device is a speaker, which may or may not also include a light source.
FIG. 1A is a schematic diagram of an exemplary networked device system in accordance with exemplary embodiments of the present invention. The system can include one or more networked master device 102 (e.g., 102-1, 102-2, . . . , 102-M) each comprising a master base unit 102 and a master head unit 106, one or more networked slave device 108 (e.g., 108-1, 108-2, . . . , 108-N) each comprising a slave base unit 110 and a slave head unit 112, one or more user device 114 (e.g., 114-1, 114-2, . . . , 114-P), one or more server 116, and/or one or more low power device 118 (e.g., 118-1, 118-2, . . . , 118-Q). Such devices and/or computers may include one or more processors, computer-readable memory, communication portals, input devices (e.g., keyboards, mice, trackballs, touchpads, touchscreens, microphones, and/or cameras, to name a few), and/or output devices (e.g., display screens and/or speakers), to name a few.
The devices and/or computers in a networked device system can also include one or more communication portals, which may handle, process, support, and/or perform any wired and/or wireless communications. Communication portals can comprise hardware (e.g., hardware for wired and/or wireless connections) and/or software. Wired connections may be adapted for use with cable, POTS (telephone), fiber (such as Hybrid Fiber Coaxial), xDSL, to name a few, and wired connections may use coaxial cable, fiber, copper wire (such as twisted pair copper wire), and/or combinations thereof, to name a few. Wired connections may be provided through telephone ports, Ethernet ports, USB ports, and/or other data ports, such as Apple 30-pin connector ports or Apple Lightning connector ports, to name a few. Wireless connections may include any cellular or cellular data connections (e.g., digital cellular, PCS, CDPD, GPRS, EDGE, CDMA2000, 1×RTT, Ev-DO, HSPA, UMTS, 3G, 4G, and/or LTE, to name a few), Bluetooth, Wi-Fi, radio, satellite, infrared connections, ZigBee communication protocols, and/or other electromagnetic waves, to name a few. Communications interface hardware and/or software, which may be used to communicate over wired and/or wireless connections, may comprise any of Ethernet interfaces (e.g., supporting a TCP/IP stack), X.25 interfaces, T1 interfaces, and/or antennas, to name a few. The components in a networked device system may be connected directly and/or indirectly, e.g., through a data network 5, such as the Internet, a telephone network, cellular data network, mesh network (e.g., using a broadcast/scan mesh network protocol, such as a protocol using gossip routing), Wi-Fi, WAP, LAN, WAN, to name a few. Various audio streaming protocols, such as Apple AirPlay and/or Google Cast may be employed by participants in the networked device system. Such audio streaming protocols may function over the communications protocols described herein, such as Wi-Fi and/or Bluetooth. In embodiments, the networked devices of the present invention may combine powerline networking with mesh or other wireless networking to extend control from one circuit to multiple circuits.
In an exemplary mesh network protocol, each device may broadcast messages and each receiving device may re-broadcast the message once. Data packets sent through such a mesh network may time out such that devices may not re-broadcast the message after the timeout. Acknowledgement may be required for certain messages. For example, when a dimmer knob is moving, the new states of the knob may be broadcast to control networked lighting devices. When the knob stops moving, the state may be broadcast with a requirement of acknowledgement to ensure that each networked device adjusts its state according to the control input via the dimmer knob.
Still referring to FIG. 1A, a networked device may be a networked master device 102 or a networked slave device 108. A networked master device 102 may communicate with an external data network, such as the Internet, and/or may communicate with one or more user device 114. A networked master device 102 may have longer transmission range and/or greater processing power. In embodiments, a networked master device 102 may serve as a hub for controlling and/or communicating with one or more other devices in the system. For example, each room in a house may contain one networked master device 102, through which a plurality of other devices in communication range (e.g., in the room) may participate in the networked system. Such other devices may be networked slave devices 108, which do not connect to an external network and/or which have limited communication range, such as through Bluetooth or Bluetooth Low Energy communication protocols.
A networked device may be a networked master device 102 or a networked slave device 108. A master device may serve as a hub to provide communication between one or more slave devices and one or more other devices or networks. In embodiments, a networked device may be a fully networkable device without requiring intermediate connection to or control from a master device. In embodiments, a networked device may comprise a base unit and a head unit, as described herein with respect to FIG. 2B. Accordingly, a networked master device 102 may comprise a master base unit 104, as described herein with respect to FIG. 3A, and a master head unit 106, as described herein with respect to FIG. 3B. A networked slave device 108 may comprise a slave base unit 110, as described herein with respect to FIG. 4A, and a slave head unit 112, as described herein with respect to FIG. 4B. A networked device can comprise (e.g., in the head unit) a light (e.g., light emitting diode (LED) lighting device, multi-color light), a wireless speaker (e.g., mono or stereo), a wireless SD and/or HD camera, a microphone, a display device (e.g., monitor, projector), an air quality sensor (e.g., smoke detector, carbon monoxide sensor, nitrogen dioxide sensor, and/or pollution sensor), an environmental sensor (e.g., temperature and/or humidity sensor), an ambient light sensor, heating and/or cooling device (e.g., a fan or hearer), a battery backup device, a Pico projector, a motion detector (e.g., an occupancy sensor, infrared sensor (e.g., comprising an infrared blaster), ultrasonic sensor), and/or a skeletal sensor (e.g., to track body position or body movement, such as a Microsoft Kinect sensor), to name a few.
A user device 114 may be a computer, laptop computer, tablet computer, mobile phone, smart phone, personal digital assistant, remote control, or other user electronic device, as described herein with respect to FIG. 13. A server 116 may be a computer system comprising one or more computers. A server 116 may be a cloud computing system, which may be owned, managed, and/or maintained by a third party. An exemplary server is described herein with respect to FIG. 14.
A low power device 118 may be a low-powered (e.g., coin battery cell powered) or passively powered (e.g., Bluetooth Low Energy) device. A low power device 118 may be a key fob (e.g., worn on the person or on a keychain of a user), doorknob, remote control, and/or light switch, to name a few. In embodiments, a low power device 118 may be a near field communication device such as an iBeacon device 132. Such devices may have location awareness, e.g., by determining whether they are in range of another device and/or by determining an approximate distance to one or more other devices. In embodiments, the one or more other devices may make the determination of whether a low power device 118 is within range or the determination of a distance or approximate distance to the device. In embodiments, the other devices may receive generic control signals from the low power device 118, which each other device may interpret differently. A low power device 118 may have one or more buttons, which can be programmable to provide different controls or to control different devices. Control output may be based on environmental scenarios such as location, time of day, weather, proximity, and/or user information (e.g., profile settings), to name a few. For example, a key fob device can be designed so that when it is within range of a light bulb that is part of the networked system and when one of the key fob buttons is pressed, the resulting control output can toggle the state of that light bulb (e.g., on or off).
In embodiments, a low power device 118 may comprise a switch, which may be a Bluetooth switch device. The device may be installed (e.g., hung, mounted, or otherwise affixed) on a wall, a door, a countertop, furniture, and/or an appliance, to name a few. Such a device may be programmed to perform specific tasks, e.g., based on various environmental scenarios. For example, such a switch device can be placed on the outside of an apartment door and when pressed can play audio over a networked wireless speaker device or flash one or more networked lighting devices in a networked device system. In embodiments, a Bluetooth switch may mount on top of an existing light switch that stay in the on position while the Bluetooth switch can communicate with a networked system to change power to a core device (e.g., in order to change light level or sound volume). In another embodiments, a Bluetooth switch may be a replacement light switch (e.g., installed in a wall and attached to a room's electrical wiring). Such a switch may remain in the on position, always delivering power to a socket in which a base unit of a networked device is fitted. The switch may then communicate with the base unit to effect control of the head unit.
FIG. 1B is a schematic diagram of exemplary communication paths in an exemplary networked device system. Communicating can comprise sending and/or receiving data (e.g., data packets).

FIGS. 7A-K illustrate various views of an exemplary networked device 700 in accordance with the present invention. The exemplary networked device can comprise a speaker and/or a light source. In embodiments, the device may have an auxiliary function, such as audio playing provided by an auxiliary device (e.g., a speaker), in addition to the primary function as a light source and an ancillary function as a diffused light source (e.g., a night light). Accordingly, in embodiments, the device may serve as an A19 light bulb, which may be provided in addition to a function provided by an auxiliary device (e.g., as a speaker, camera, sensor, or spot light, to name a few). The exemplary networked device 700 is described with respect to a speaker embodiment, although the device may comprise other auxiliary devices, such as a camera, a microphone, an air quality sensor, a motion sensor, an occupancy sensor, a Wi-Fi repeater, or an infrared blaster, to name a few. Accordingly, the speaker control components described herein may be replaced with respective auxiliary device control components. In embodiments, a networked device may not function as a light source, e.g., an auxiliary device without the primary lighting LEDs. In other embodiments, a networked device can include multiple auxiliary devices and may have additional PCBs (e.g., a PCB configured to control each auxiliary device).
As seen in FIGS. 7A and 7B, the device 700 may have an outer globe 702 at the upper portion of the device. The outer globe 702 may be transparent. In embodiments, the outer globe 702 may be translucent, filtering out or scattering some light from the light source. In embodiments, the outer globe 702 may be constructed from clear copolyester or glass. The outer globe 702 may be frosted to reduce the amount of light that passes through it and/or to scatter light. A transition ring 708 may connect the globe 702 to the cowling 704, which forms the outer portion body of the lower portion of the device 700. In embodiments, the transition ring 708 may be threaded to couple the upper and lower portions of the networked device 700. In embodiments, the upper and/or lower portions and the transition ring 708 may snap together. At the base of the device 700 a threaded connector 706 may be configured to attach to a light socket. The threaded connector 706 may be an Edison screw. The threaded connector 706 may be manufactured in different sizes (e.g., 5-40 mm base diameters including the external threads) to fit within various sockets (e.g., E5, E11, E12, E14, E17, E27, E27, E39, E40 socket sizes, to name a few), as socket sizes may differ among lighting base units or lighting sockets installed in buildings and/or may differ among countries and/or regions. In embodiments, the device 700 may be configured to attach to different types of light sockets, which may or may not require a threaded attachment. For example, the networked device 700 may be adapted to attach to fluorescent light sockets. In embodiments, adapters may be provided to connect the device 700 to a variety of sockets. The light sockets may provide power to the device, as discussed herein.
FIGS. 7C and 7D show that the networked device 700 can include an aperture 710 in the center of the top of the globe 702. The aperture 710 may simply be an opening in the structure of the globe 702.
FIGS. 7E and 7F show an exemplary globe 702A for a networked device 700A with a speaker auxiliary device. Speaker hardware 714 may be fitted within an aperture 710A or below the aperture 710A.

Such a device can include a spot globe cap 703 across the top of the aperture 710B in globe 702B. The spot light source may be a single light bulb or an arrangement of a plurality of discrete light sources, such as a plurality of LEDs, as described herein.
FIG. 7I is a section view of the exemplary networked device 700A corresponding to a speaker embodiment of the networked device 700. The components described with respect to the speaker embodiment 700A may be largely the same as or similar to the components of other embodiments, with the primary difference being the communication and control printed circuit board (PCB) and speaker hardware, which would be replaced with hardware and a corresponding communication and control PCB configured to perform the auxiliary function of the device, such as a spot light or a camera.
Below the globe 702A is a diffuser 712. The diffuser may be translucent, which may be achieved via a textured and/or polished surface. The diffuser may be made from translucent, clear copolyester. The diffuser may scatter light so as to soften the light emitted from the device 700. The diffuser may be used to provide light without a spotlight effect. The diffuser may also blend light from a plurality of LED light sources, which LEDs may provide light at differing wavelengths (and accordingly, differing colors), as described herein. The diffuser 712 may combine these discrete sources of light to provide a uniform glow, e.g., uniform in brightness and/or color. In embodiments, the diffuser 712 may scatter light that is emitted directly into the diffuser. The diffuser 712 may also scatter light that is transported to the diffuser (e.g., to an inner surface of the diffuser) via one or more light pipes. A light pipe may be a solid conduit comprised of transparent and/or translucent material, such as glass or clear copolyester. In embodiments, light pipes may be hollow and/or non-rigid. In embodiments, a light pipe may be a cylindrical member with a flat surface at a first end that contacts an LED. For example, LEDs, such as RGB LEDs on the indicator PCB, may each contact a light pipe, which transports light emitted from those LEDs to the diffuser 712. This configuration can enable the diffuser to glow, such as to create the effect of a ring of light (e.g., colored light) within the head of the lighting device. The aperture 710 may extend through the diffuser 712.
A speaker comprising a speaker driver 714 may be located within the aperture or within the channel formed by the aperture through the globe 702A. The speaker driver 714, which is a transducer that can produce sound waves from electrical signals, may be recessed from the top of the globe 702A. All or part of the aperture channel may comprise cylindrical shape or a conical shape forming a conical cylinder. In embodiments, the aperture channel may have a different diameter through all or part of its length, such as a parabolic cross-section viewed along the length. The aperture channel may thus provide directional focus and/or amplification of sound waves. In embodiments, the speaker may be attached to the globe.
A communication and control PCB 720 may be a communication and speaker control PCB comprising circuitry for audio generation and/or audio controls. In embodiments, the communication and control PCB 720 can include some or all of the communications circuitry and/or other communications hardware of the device 700A. Communications circuitry can include one or more chipsets and/or antennas. For example, the communications and control PCB 720 may also include Wi-Fi communications hardware. A communications and control PCB may also comprise one or more microprocessors, which may be used to control certain communications (e.g., Wi-Fi and Internet-based communications) and/or speaker operation (e.g., volume controls, audio generation, surround sound integration, to name a few). Such a PCB is described in greater detail with respect to FIGS. 9C and 9D.
In embodiments where the networked device 700 is not a speaker, the speaker driver 714 may be replaced with different hardware, such as a camera, one or more sensors, and/or another light source (e.g., a spot light source). Instead of a speaker control circuitry as found in PCB 720, a non-speaker networked device 700 can include a communications and control PCB comprising circuitry for the auxiliary device hardware, e.g., camera circuitry, sensor circuitry, spot light source comprising, which may comprise a plurality of LEDs (e.g., clustered LEDs), to name a few.
Components within the networked device 700A may be mounted to a chassis 716, which may hold the components, such as the PCBs and/or the auxiliary device (e.g., the speaker driver 714), fixed in their respective positions.
Other PCBs in the networked device 700A can include an indicator PCB 718. The indicator PCB 718 may comprise one or more LEDs (e.g., four, five, or six LEDs, to name a few), which can be used to provide alerts and/or signals, such as by flashing a specified number of times and/or changing colors. In embodiments, the LEDs may provide a secondary light source, such as low output light, as may be used for a night light. These LEDs may provide colored light output (e.g., RGB LEDs outputting colored light of various effective visible wavelengths through combinations of red, green, and blue light). Light from these LEDs may be diffused through the diffuser 712. In embodiments, the RGB LEDs may be positioned in proximity to and/or may contact a light pipe, which can transport the light to the outside surface of the networked device, such as to form a circular ring around the device. In embodiments, this secondary light source may provide light to a light pipe, which transports the light to the surface of the device, e.g., as a band around the device. An indicator PCB 718 can also include additional communications circuitry, such as a Bluetooth Low Energy communications chipset. An indicator PCB 718 can also include one or more microprocessors, which may control lighting and/or certain communications, such as mesh network communications. An exemplary indicator PCB is described herein with respect to FIGS. 9E and 9F.

Additional components may be mounted in the lower base portion, e.g., at and/or below the transition ring 708 and contained within the cowling 704. A radiator 724 may dissipate heat from processing the input power, such as transforming input alternating current (AC) power to direct current (DC) power. The radiator 724 may be a heat sink, which may have no moving parts (e.g., milled metal with pins and/or fins to promote convective heat transfer). In embodiments, the radiator 724 may dissipate heat from other PCBs (e.g., heat generated by the circuitry and/or processors) and/or from the LEDs or other heat-producing hardware.
A power control PCB 722 may be located within the radiator 724. The power control PCB 722 may be configured for AC power processing, such as modulating the power delivered (e.g., to other PCBs and/or hardware components) and/or transforming input AC power to a DC output (e.g., to power the LED lights). Power control PCBs are described herein in greater detail with respect to FIGS. 9A and 9B.
At the base of the device 700A an insulating cap 728 may be positioned within the interior of the threaded cap 706. The insulating cap 728 may reduce the heat transferred to the threaded cap 706 so as to avoid melting of socket components and/or to avoid temperatures too high for safe human touch. A retaining ring 726 may form the connection between the threaded cap 706 and the cowling 704.
Turning to the exploded views shown in FIGS. 7J and 7K additionally illustrate the LED lighting PCB 730 of networked device 700A. Such an LED lighting PCB 730 may be included in other networked devices 700 so that those devices can function as lightbulb in addition to their auxiliary function. The LED lighting PCB 730 may provide the primary light source for the networked device 700A. A plurality of LEDs may be arranged on the LED lighting PCB 730, such as around its perimeter. The light from these LEDs may be diffused through the diffuser 712. The LEDs may comprise alternating white and yellow LEDs or other such patterned arrangements. LED lighting PCBs are described herein with respect to FIGS. 9G and 9H.

A camera 814 may be located within an aperture 810 in the top of the globe 802. A camera support disk 836 may support the camera 814 and/or fix it in position within the aperture 810. Light from an LED lighting PCB 830 may be diffused through a diffuser 812 located within the head of the device 800, encapsulated by globe 802. A heat spreader 834, such as an LED heat spreader, may be a heat sink coupled to the LED lighting PCB 830 to facilitate heat dissipation from the LED lighting PCB 830. In embodiments, such a heat sink may be found in other networked devices, such as networked device 700.
An indicator PCB 818 can include one or more LEDs, which may be RGB LEDs capable of emitting light at different wavelengths. Light emitted from LEDs mounted on an indicator PCB 818 may also be channeled through the diffuser 812. In embodiments, communications circuitry and/or other communications hardware may be mounted on the indicator PCB 818. Such communications circuitry and/or hardware can include a Bluetooth Low Energy chipset. The indicator PCB 818 may include one or more microprocessors, which may control certain communications and/or lighting. A communications and control PCB 820 can include camera control circuitry. In embodiments, the communications and control PCB 820 may include one or more microprocessors, which may control certain communications (e.g., Wi-Fi communications) and/or the camera (or a different auxiliary device). It may be operably connected to the camera module 814. The communications and control PCB 820 may also include communications circuitry and/or hardware such as chipsets and/or antennas. In embodiments, such communications circuitry and/or hardware can provide Wi-Fi communications.
Components such as the LED lighting PCB 830, LED head spreader 834, indicator PCB 818, and/or communications and control PCB 820 may be mounted to a chassis 816. The chassis 816 may be positioned at the base of the head portion of device 800, above the cowling 804. A power control PCB 822 may be operably connected to one or more of the other PCBs.

FIGS. 9A-H illustrate exemplary PCB components and/or layouts. FIGS. 9A-B show an exemplary power control PCB. Although these drawings are described with respect to a top view and a bottom view, it will be understood by one skilled in the art that such designations may not refer to the orientation of the power control PCB within the device. For example, the power control PCB may actually be oriented along the longitudinal axis of the networked device, within the base portion of the device and thus the faces designated as top and bottom may actually be oriented to face the sides of the device. The power control PCB may have a power input 908, such as a 120V AC power input. A power converter 910 may be adapted to convert the input alternating current to direct current for output. The power converter may comprise one or more rectifiers, capacitors inductors, and/or switching elements. The power converter may use a switch mode power supply principle to convert AC voltage, which may be utility power, to DC low voltage, which may be required by the logic and/or radio (e.g., communications) circuits of the networked device. The DC power output by such an AC/DC power converter may be routed to a voltage regulator 912. The voltage regulator 912 may stabilize the output voltage from the power control PCB. Accordingly, the voltage regulator 912 may maintain one or more constant voltages that it then outputs to one or more current control components (e.g., current control components 902, 904, and 906). For example, a constant voltage of 5V may be output to the logic components, while 50-60V may be output to the LEDs. Lower and higher voltages are possible, as required by the components of the networked device. The current control components can govern the current output to one or more of the other PCBs within device 900. Current control component 902 may be a logic power supply current control component, which may form part of a logic power supply. In embodiments, it may provide 5V to Wi-Fi communications components and/or 3.3V to Bluetooth Low Energy communications components. Current control component 904 may form part of the power supply to an LED driver, to power the LEDs. Meanwhile, current control component 906 may be an LED driver current control component, which is part of the LED driver itself. It can provide constant current for the LEDs.

The control laws may run on the processor 936, which may interpret received commands, evaluate control laws, and/or generate machine-readable instructions for controlling various device components. For example, the control laws be evaluated to generate instructions to identify when and how to adjust LED output, such as by reducing power to the LED lighting PCB. The communications and control PCB may include one or more connectors 938 (e.g., connectors 938-1 and 938-2), which can be operably connected to the LED lighting PCB and/or the indicator PCB. In embodiments, the communications and control PCB may connect to hardware for performing the device's auxiliary functions, such as a camera, a speaker driver, and/or a spot light (e.g., a clustered LED array).

The warm and cool LEDs may be controlled separately to adjust the effective wavelength that is output, such as by increasing the warm LED output, decreasing the warm LED output, increasing the cool LED output, and/or decreasing the cool LED output. In embodiments, the output (light intensity) of both warm and cool LEDs may be controlled together, such as to dim the light or increase the brightness. The LED lighting PCB can include a temperature sensor 982, which may be used to prevent overheating, such as by triggering a shut-off or dimming of the LEDs.

Such an interface may list and/or identify various network topology data, which can correspond to networked devices (e.g., such network topology data can comprise electronic identifiers and/or device names), groups of devices, locations of devices, and/or regions in a networked system (e.g., kitchen, master bedroom). The interface may also identify new devices, which may be devices recently added to the network and/or devices whose settings (e.g., timer settings) have not yet been set. In embodiments, the interface may identify available devices (e.g., network capable devices that are within range of the network) that are not yet connected to the network. The network topology data (e.g., electronic device identifiers, device setting data, device location data, may be received at the mobile application from a server with access to network topology data stored in one or more databases. In embodiments, the network topology data may be stored locally on the user electronic device. The interface may allow a user to select a device to view and/or edit device information (e.g., device settings, device groups, device region information, to name a few).
FIG. 16C shows an exemplary interface for connecting a new device, such as a light bulb. The interface may provide data input and/or selection fields whereby a user may input a device name, select and/or create one or more groups to associate with the device, and/or input and/or select a network identifier (e.g., a network name). In embodiments, the user may be required to input a device identifier, which may be a unique code assigned to the device, e.g., at the time of manufacturing.
FIG. 16D shows an exemplary interface for creating a device group. In embodiments, the interface may provide a data input field for a user to input a group name. The interface may also provide a device selection option so that a user may select one or more device to be included in the group. For example, a user may associate a plurality of speaker devices with a “TV speaker” group or may associate a plurality of lights located at a kitchen island with a “Kitchen Island” group. A user may then control the group of devices collectively through a single control input. For example, a user may turn off all devices (e.g., all lights) associated with an exemplary Kitchen Island group without inputting separate control commands to turn off each device. A user may also dim the group of lights, which may dim each light by the same amount.
FIG. 16E shows a settings interface, which may allow a user to access and/or manage account settings (e.g., user credentials, billing information), groups settings (e.g., create groups, delete groups, combine groups, add devices to groups, remove devices to groups, rename groups, to name a few), and/or scenes settings (e.g., create new scenes, delete scenes, edit scenes, to name a few). Scenes may comprises device settings for particular scenarios, such as watching TV, eating dinner, going to sleep. A user may select a scene to execute the corresponding settings (e.g., values for each device load or group of device loads). Devices may be added to a scene, removed from a scene, and/or values of the load (e.g., power level, light brightness, speaker volume, to name a few) of each device may be adjusted.
FIGS. 17A-E are exemplary screen shots of an application for networked device control settings. As described with respect to FIGS. 16A-E, such settings may be administered using a server and/or a local user electronic device.
FIG. 17A shows an interface comprising control options for a particular networked device, which in this exemplary embodiment is named “Bedside Lamp” and is located in the “master bedroom”. The interface may show a current value of the device load, e.g., 72% (which may correspond to 72% of power and/or 72% brightness of the light). The interface may present one or more settings options for the device, such as an alarm clock, proximity lighting, transitional lighting, and/or environmental lighting, as described herein.
FIG. 17B shows an alarm clock interface for a networked device. One or more alarm times may be added, which may correspond to times at which a device will be activated and/or deactivated and/or when a load value will be changed (e.g., power increased). Alarms may be recurring (e.g., each day, each week), and/or alarms may be named (e.g., “Weekdays”, “Weekends”). Alarms may be toggled on and/or off.
FIG. 17C shows an exemplary proximity lighting interface. Proximity lighting may utilize geofencing features, which may allow location-based boundaries to be defined (e.g., associate a location with a user's home). Proximity lighting features may use one or more devices and/or methods for determining location, such as a GPS device (e.g., within a mobile phone), signal triangulation (e.g., among networked devices), and/or signal strength determinations. One or more rules may be set by a user based upon proximity settings, from which the mobile application and/or a server may generate electronic proximity rules. For example, when a user arrives at a location (e.g., a home location) one or more devices may be activated, and/or when a user departs a location one or more devices may be deactivated. Accordingly, when a user arrives home certain lights may be activated. Networked devices may be deactivated (e.g., powered off) when a user departs the home location.
FIG. 17D shows an exemplary transitional lighting interface. One or more device load settings may be changed based upon identified transitional points in time. Transitional times, such as sunset, may be received from a server or other computer system. Other transitional times may be set by a user, such as a bedtime, a “kids bedtime”, and/or a Sabbath time (e.g., a period of time during which devices must be activated or deactivated without a user's direct control), to name a few. At such transitional times, load values may be changed to turn a device off, on, and/or adjust its load (e.g., a low-power nightlight setting). In other embodiments, the type of load or an output quality of the device may be adjusted (e.g., white light in the morning, such as by using a core lighting device, and yellow light at night, such as by using an auxiliary light).
FIG. 17E shows an exemplary environmental lighting interface. Device loads may be adjusted based upon one or more environmental situations, such as sunrise, sunset, and/or weather (e.g., turn lights on during a day when it is raining). Such environmental situations may be input by the user, detected by sensor devices (which may be a part of a given networked device, attached to networked device, and/or a separate networked device), and/or received from an external source (e.g., a server or computer system via the Internet).
FIG. 18 is flow chart showing network topology connection laws specially programmed into the networked device in accordance with exemplary embodiments of the present invention. The connection laws may control the communications protocols used to communicate with various target devices. The connection laws may comprise a preferred ordering of communications protocols (e.g., use Bluetooth Low Energy before Wi-Fi). The connection laws may also comprise connectivity thresholds for evaluating suitable connectivity to maintain communications via a given communications protocol. Accordingly, a device may measure latencies of each of its connections, and the connection laws may comprise evaluation of the latencies. In embodiments, connection laws can comprise determining a connection of least resistance. The connection laws may identify specific communications protocols to use for specific device types (e.g., computers, smart phones, other networked devices, servers, to name a few). The networked device may determine whether the target device is within range of Bluetooth, which may include determining whether a Bluetooth signal from the target device meets or exceeds a threshold signal strength. In a step S1802, if within Bluetooth range, the networked device may determine at step S1804 to communicate via Bluetooth and/or Bluetooth Low Energy. If not within Bluetooth range, the networked device may determine in a step S1806 whether the target device is connected to the same local area network (LAN), which may be a wireless local area network. If connected to the same LAN, the networked device may determine at a step S1808 to communicate with the target device via the LAN, such as using Wi-Fi. If not on the same LAN, the networked device may determine at a step S1810 to communicate with the target device (e.g., a server, smart phone not connected to Wi-Fi, remote computer, to name a few) using a cloud-based network. The cloud-based network can comprise communication over the Internet. Accordingly, the networked device may use Wi-Fi to connect to the Internet through a router. In embodiments, a plurality of external data networks may be involved, such as the Internet and a cellular data network by which the target device accesses the Internet.
Networked devices of the present invention may be programmed to synchronize state. States can include on/off, power level (e.g., corresponding to brightness of a light), volume level, to name a few. For on/off states, turning off a first networked lighting device may cause other associated networked devices (e.g., associated through a group defined using the software) to turn themselves off. Each of a group of networked devices can detect when another member of the group leaves the network (e.g., which may correspond to the device being turned off). Networked devices may broadcast or otherwise transmit periodic signals that identify their states. If a signal from a particular device is not received by one or more other networked devices for a predefined number of transmission cycles (e.g., one, two, or three consecutive cycles, to name a few), the other devices may be programmed to turn off. Accordingly, changing the state and/or turning off a single device may provide a sufficient input to adjust the states of grouped devices. In embodiments, a single device may be designated as the master device, and the other networked devices will adjust state to match the master device. For example, the master device may be a networked device (e.g., networked lightbulb) connected to a switch, such as a wall switch. The other slave devices may not be connected to switches. The present invention provides a mechanism to extend the switch input to the slave devices.
FIG. 19 shows an exemplary networked control device 1900 in accordance with the present invention. The networked control device 1900 may be alarm clock 1900. It may include control hardware (e.g., circuitry, antennas, and/or input hardware) for programming or otherwise transmitting control signals to networked devices. Accordingly the networked control device 1900 can include buttons and/or a capacitive touch area 1902 to detect and/or receive user inputs. It can also include a display 1904, which may be a high resolution display screen and/or an e-paper display. An e-paper display may be characterized by low power consumption. The display 1904 may show the time, date, weather, and/or menu information for controlling one or more networked devices, to name a few. The networked control device 1900 can comprise one or more lighting devices 1906 (e.g., 1906-1 and 1906-2), which may function as reading lights and/or which may provide screen illumination, such as for an e-paper display screen. The lights 1906 may be contained within the display bezel. A dimmer knob 1908 or other input device (e.g., buttons or touch capacitive area) may receive user inputs, which it may correspond to requests to dim the lights 1906 and/or networked lighting devices. In embodiments, such a knob 1908 may serve as a control input for other networked devices, such as speakers. The networked control device 1900 can thus provide control over networked devices to turn them on and/or off and/or to adjust their output (e.g., reduce or increase speaker volume, dim or brighten lights). The control device 1900 can provide light-based waking (e.g., to increase light output gradually in accordance with a scheduled alarm time). The control device 1900 can perform sleep tracking to track sleeping state of an individual in proximity to the device. Such tracking may utilize motion sensors and/or audio sensors (e.g., microphones) to detect breathing.
In embodiments, the control device 1900 can provide audio streaming to other networked devices. In embodiments, it can include an audio line in for connecting to wired audio outputs from audio devices (e.g., radios, mp3 players, to name a few). Audio streaming may be achieved using any of a variety of audio streaming protocols, such as Apple Airplay and Google Cast. Bluetooth Low Energy may be used to communicate with other devices. In embodiments, the device itself my output audio, such as by streaming music or other audio content. The device 1900 may receive updates from an external data network, such as weather, news, and/or calendar events, which may be displayed on the screen 1904 and/or may be communicated through audio. Accordingly, the device can include one or more speakers. A speaker may be provided in an audio cavity, which may increase the quality of the output sound without increasing the size of the speaker. Information may be provided through audio using text to speech sound generation and/or by relaying received audio content. Accordingly, the device may stream audio content from one or more sources, including radio broadcasts and/or Internet sources. The device may have charging ports (e.g., USB ports) for charging user electronic devices, such as smart phones and/or tablets. In embodiments, the control device 1900 may be a clock or alarm clock that is not used to control other networked devices. In embodiments, user devices may operatively connect to the control device 1900, e.g., to adjust its settings and/or its programming. Such connection may be made over Bluetooth and/or Wi-Fi, to name a few.
Now that embodiments of the present invention have been shown and described in detail, various modifications and improvements thereon can become readily apparent to those skilled in the art. Accordingly, the exemplary embodiments of the present invention, as set forth above, are intended to be illustrative, not limiting. The spirit and scope of the present invention is to be construed broadly.
