The smart devices can further communicate with each other via a connection to a network , such as the Internet. Through the Internet, the smart devices may communicate with a central server s or a cloud-computing system s , hereinafter system The system may be associated with a manufacturer, support entity, service provider associated with the device, etc.
In one example, a user may be able to contact customer support using a device itself rather than needing to use other communication means such as a telephone or Internet-connected computer. Further, software updates may be automatically sent from the system to the smart devices in the example environment such as when available, purchased, at routine intervals, and etc. Here, it is contemplated that some of the smart devices in the example environment may generally be battery powered, while others may have access to a regular and reliable power source, such as by connecting to line-voltage wires behind or within the walls of the structure The smart devices that have a regular and reliable power source may be referred to as spokesman nodes.
These nodes are equipped with the capability of using any wireless protocol or manner to facilitate bidirectional communication with any of a variety of other devices in the example environment , as well as with the system On the other hand, the devices that are battery-powered may be referred to as low-power nodes.
Unusual sizes
Further, some, but not all, low-power nodes may be incapable of bidirectional communication. These nodes may send messages, but may be are unable to listen. As described, the smart devices serve as low-power and spokesman nodes to create a mesh network in the example environment Individual low-power nodes in the smart home environment may regularly broadcast messages regarding what they are sensing and the other, low-powered nodes in the smart home environment, in addition to sending out their own messages, may repeat the messages, thereby causing the messages to be transferred from node to node or device to device throughout the example environment Thus, the low-powered nodes using low-power communication protocols may send messages across the entire example environment as well as over the network to the system According to examples, the mesh network enables the system to regularly receive data from all of the smart devices in the home, make inferences based on the data, and send commands back to one or more of the smart devices to accomplish some of the smart home objectives as discussed throughout.
As described, the spokesman nodes and some of the low-powered nodes are capable of listening. Accordingly, users, other devices, and the system may communicate controls to the low-powered nodes. For example, a user may use the mobile device to send commands over the network to the system , which then may relay commands to the spokesman nodes in the example environment The spokesman nodes may drop-down to a low-power protocol to communicate the commands to the low-power nodes throughout the example environment , as well as to other spokesman nodes that did not receive the commands directly from the system An example of a low-power node is a particular hazard detector Other examples of low-powered nodes include battery-powered versions of a hazard detector Furthermore, hazard detectors may send messages to other smart devices, sensors, etc.
Examples of spokesman nodes include smart doorbells , smart thermostats , wired versions of hazard detectors , smart wall switches , and smart wall plugs interfaces These devices may be located near and connected to a reliable power source, and therefore might include more power-consuming components, such as one or more communication chips capable of bidirectional communication in any variety of protocols.
In some examples, the low-powered and spokesman nodes of the example environment may function as alarm broadcasters for a hazard-detection system in the example environment For example, in the event a particular hazard detector detects a hazardous condition, such dangerous amounts of smoke or carbon monoxide, that hazard detector may send an alarm message to the system , which may then instruct other smart devices in the example environment to instantiate an alarm, alerting occupants or other individual to or of the dangerous condition.
Thus, the hazard-detection system could be enhanced by various low-powered and spokesman nodes located throughout the example environment , all capable of providing audible, visual. In this example, a user could enhance the safety of the example environment by purchasing and installing extra smart devices capable of alerting occupant to dangerous conditions. Referring now to FIG. In this example, the platform is shown to include various remote servers or cloud computing architectures. As mentioned above, it is contemplated that each of the intelligent, network-connected smart devices of FIG.
Although in some examples provided herein, elements of the example platform may communicate with and collect data from various smart devices of the example environment of FIG. For example, the system see also FIG. Thus, various elements of the example platform may routinely collect data from homes across the world. In general, the home data may include, for example, power consumption data, occupancy data, HVAC settings and usage data, carbon monoxide levels data, carbon dioxide levels data, volatile organic compounds levels data, sleeping schedule data, cooking schedule data, inside and outside temperature humidity data, television viewership data, inside and outside noise level data, and so on and so forth in which the type of home data as collected is only limited by type or form of smart devices as incorporated into a particular environment, such as the example environment of FIG.
According to examples, smart devices may increase their logging frequency as they approach a threshold. For example, a particular hazard detector may increases the frequency at which it samples air and sends corresponding data to the system as the condition in the home approaches an alarm condition.
For example, upon detecting more than a threshold level of smoke, a particular hazard detector may samples air at a higher rate and send corresponding data to the system In another example, a particular hazard detector may increases the frequency it samples air for CO upon detecting a threshold level increase in the amount of CO in the home.
Further, for example, a particular hazard detector may increase logging and sampling frequency during transitions. For example, upon detecting increased levels of noise, light, etc. The increased levels of noise, light, etc.

For example, it may be desirable that the smart devices be quiet most of the time so as to reduce chatter on the network, e. Thus, if no one is in the room, a smart device may be configured to sample once a minute or once an hour. However, if the smart device senses a transition indicating that a person is in the room, then it will sample more often. For example, when the room is occupied, the smart device may send to the system temperature data, occupancy data, etc. The server stores this data in home data and runs trend detecting algorithms against the data. In some examples, the home data may be stored to a persistent memory location of a particular hazard detector itself.
For example, end-users may review historical CO, smoke, temperature, etc. This may enable the user to see that an alarm condition occurred in the home and how it was resolved. The historical log may also include a history of self-checks executed by a particular smart device.
For example, the historical log may show a history of time the hazard detectors have tested their CO sensors. An example self-check log may indicate that all hazard detectors in the home self-checked between 1 AM and 2 AM, and they are all working properly, including their WiFi connection is of sufficient strength, their battery level is acceptable, their CO sensor is working properly, and etc.
Still further, a historical log may be leveraged as part of an algorithm to enable a hazard detector to self-adjust its own settings, such as particular threshold level settings for example. Referring still to the system , it is contemplated that the system may further provide one or more services Data associated with the services may be stored at the example system , and the system may retrieve and transmit the data at an appropriate time such as at regular intervals, upon receiving a request from a user, and etc.
As illustrated in FIG. The analyzed data may in some examples be stored as derived home data Results of the analysis or statistics may thereafter be transmitted back to the device that provided home data used to derive the results, to other devices, to a server providing a webpage to a user of the device, or to other non-device entities. The results or statistics may be provided via the network In this manner, the processing engine may be configured and programmed to derive a variety of useful information from the home data A single server can include one or more engines.
Still other examples are possible. The derived data can be highly beneficial at a variety of different granularities for a variety of useful purposes, ranging from explicit programmed control of the devices on a per-home, per-neighborhood, or per-region basis for example, demand-response programs for electrical utilities, to the generation of inferential abstractions that can assist on a per-home basis, for example, an inference can be drawn that the homeowner has left for vacation and so security detection equipment can be put on heightened sensitivity, to the generation of statistics and associated inferential abstractions that can be used for government or charitable purposes.

For example, processing engine may generate statistics about device usage across a population of devices and send the statistics to device users, service providers or other entities for example that have requested or may have provided monetary compensation for the statistics. In some examples, to encourage innovation and research and to increase products and services available to users, the example platform may expose a range of API's Application Programming Interface to third parties, such as charities , governmental entities , such as the Food and Drug Administration or the Environmental Protection Agency, academic institutions , such as university researchers, businesses , such as for providing device warranties or service to related equipment, targeting advertisements based on home data, utility companies , and various other third parties.
In general, the APIs may be coupled to and permit third-party systems to communicate with the example system , including the services , the processing engine , the home data , and the derived home data For example, the APIs may allow applications executed by the third parties to initiate specific data processing tasks that are executed by the system , as well as to receive dynamic updates to the home data and the derived home data Even though devices situated in smart home environments will have an endless variety of different individual capabilities, they can all be thought of as sharing common characteristics in that each of them is a DC Data Consumer , a DS Data Source , a SC Services Consumer , and a SS Services Source Advantageously, in addition to providing control information needed for the devices to achieve their local and immediate objectives, elements of the example platform may also be configured to harness the large amount of data that is flowing out of these devices.
These objectives may be predefined or adaptively identified based on, e. For example, the processing engine of FIG. For example, the processing engine may include a managed services paradigm a that monitors and manages primary or secondary smart device functions. The device functions may include ensuring proper operation of a device given user-inputs, estimating that an intruder is or is attempting to be in a dwelling, detecting a failure of equipment coupled to the device, implementing or otherwise responding to energy demand response events, or alerting a user of a current or predicted future event or characteristic.
Services, promotions, products or upgrades can then be offered or automatically provided to the user. For example, one challenge may involve participants turning down their thermostat by one degree for one week. Those that successfully complete the challenge are rewarded, such as by coupons, virtual currency, status, etc. Regarding compliance, an example involves a rental-property owner making a rule that no renters are permitted to access certain owner's rooms. The devices in the room having occupancy sensors could send updates to the owner when the room is accessed.
In accordance with the principles of the present disclosure, the processing engine may further integrate or otherwise utilize extrinsic information from extrinsic sources to improve the functioning of one or more processing paradigms. Extrinsic information can be used to interpret data received from a device, to determine a characteristic of the environment near the device such as weather outside a structure that the device is enclosed in, to determine services or products available to the user, to identify a social network or social-network information, to determine contact information of entities, e.
Another view of the example hazard detector is shown below in connection with at least FIG. In one example, the hazard detector corresponds to the hazard detector described in other sections of this disclosure, such as in connection with FIG.
In an example, the hazard detector is a smoke detector that is configured to detect the presence of smoke and sound an alarm to audibly warn an occupant or occupants of the home or structure of a potential fire or other danger. In other examples, the hazard detector may be a carbon monoxide detector, heat detector, and the like. In other examples, the hazard detector may be a multi-sensing detector that includes a smoke detector, carbon monoxide detector, heat detector, motion detector, and the like.
Many of the present teachings are particularly advantageous for examples in which the hazard detector is a multi-sensing detector, particularly since combining the various sensing modes together into a single device can pose substantial challenges with respect to one or more of device compactness, component powering, and overall component governance and coordination. In one example implementation, the hazard detector is a roughly square or rectangular shaped object having a width of approximately mm to mm and a thickness of approximately 38 mm. Stated differently, hazard detector is a multi-sensing unit having a fairly compact shape and size that may be easily attached to a wall or ceiling of a home or structure so as to be able, among other functionalities, to detect the presence of smoke and alert an occupant therein of the potential fire danger.
As shown in FIG. The hazard detector also includes a back plate that may be mounted to the mounting plate and a front casing that may be coupled with or otherwise secured to the back plate to define a housing having an interior region within which components of the hazard detector are contained.

A circuit board may be coupled with or attached to the back plate Various components may be mounted on the circuit board For example, a smoke chamber may be coupled with or mounted on the circuit board to detect the presence of smoke. In one example, the smoke chamber may be mid-mounted relative to the circuit board so that air may flow into the smoke chamber from a position above the circuit board and the below circuit board Other components, such as a motion sensor, e.
For example, when the internal components of the hazard detector are viewed, such as through vents in the back plate , the protective plate may provide the appearance of a relatively smooth surface and otherwise hide or obscure the components or circuitry of the circuit board The protective plate may likewise function to direct a flow of air from the vents of the back plate toward the smoke chamber to facilitate air flow into and out of the smoke chamber The hazard detector may also include a battery pack that provides power to the various components of hazard detector when the hazard detector is not coupled with an external power source, such as a V power source.
In a specific example, the cover plate may include a plurality of holes or openings that allow one or more sensors coupled with the circuit board to view or see through a surface of cover plate so as to sense objects external to the hazard detector The plurality of openings of the cover plate may be arranged to provide a visually pleasing appearance when viewed by occupants of the home or structure.
In one example, the plurality of openings of the cover plate may be arranged according to a repeating pattern, such as a Fibonacci or other sequence. A lens button may be coupled with or otherwise mounted to the cover plate The lens button may allow one or more sensors to view through the lens button for various purposes. For instance, in one example a PIR sensor may be positioned behind the lens button and configured to view through the lens button to detect the presence of an occupant or occupants within the home or structure.
In some examples, the lens button may also function as a button that is depressible by a user to input various commands to the hazard detector , such as to shut-off an alarm that is triggered in response to a false or otherwise harmless condition.

Positioned distally behind the lens button may be a light ring that receives light, such as from an LED Light Emitting Diode or another light emitting element, and disperse the light within the light ring to provide a desired visual appearance or cue, such as a halo behind the lens button Positioned distally behind the light ring may be a flexible circuit board that includes one or more electrical components, such as a PIR sensor, LEDs, and the like.
Referring now specifically to FIG. Specifically, the mounting plate , front casing , back plate , and cover plate are in an assembled configuration with the various other components contained within an interior space of hazard detector As briefly described above, the light ring may be used to provide a halo appearance of light around and behind lens button The hazard detector when assembled provides a compact yet robust and multifunctional device. In this example, the circuit board includes a main body having a front side or surface and a rear side or surface. Various electrical components may be mounted on circuit board , and type and form of such components may or may not be implementation-specific, and may evolve as technology evolves.
In some examples, these components may be mounted on the front surface of circuit board , on the rear surface of circuit board opposite the front surface, or on both surfaces of the circuit board Other components may be mid-mounted relative to the circuit board so that opposing surfaces are positioned on opposing sides of the circuit board as described herein.
