- FIG. 4 presents a flow diagram illustrating a method 400 for identifying an environmental condition associated with a portal, which may be performed by one of electronic devices 1 10 (FIG. 1).
- the electronic device receives measured environmental signals from one or more additional electronic devices (operation 410) mechanically coupled to the portal, where the environment signals correspond to (or are related to) vibrations and/or acoustic signals, and where the one or more additional electronic devices are at different positions on the portal.
- the electronic device analyzes the measured environmental signals (operation 412) to identify the environmental condition, where the analysis is based on historical measurements of the environmental signals (e.g., the measured environmental signals may be compared to the historical measurements to determine a change or deviation from the baseline). Note that the analysis may also be based on measurements of environmental signals associated with the portal performed by the electronic device. Furthermore, in some embodiments the analysis involves correcting the measured environmental signals for a mechanical transfer function associated with the portal based on the different positions of the one or more additional electronic devices on the portal.
- sensor mechanism 1 18-1 measures acoustic signals. This is shown in FIG. 5, which presents a drawing illustrating method 400 (FIG. 4).
- FIG. 5 presents a drawing illustrating method 400 (FIG. 4).
- sensors 510 may be positioned at antinodes in the response of portal 112 to an impulse.
- Information about preferred or predetermined positions 512 may be displayed on electronic device 1 10-1 or may be communicated to a user when they are installing sensors 510 on portal 1 12. However, in some embodiments a user positions sensors 510 at random positions 512 on portal 1 12.
- sensors 510 may communicate measured environmental signals with electronic device 110-1 via wireless communication, wired communication and/or via portal 112 (e.g., using information conveyed in vibrations, such as a modulated waveform having a fundamental frequency that is within or outside of a range of human hearing).
- the communication may include unique identifiers of sensors 510 so that electronic device 1 10-1 can be associated the measured environmental signals with their source (i.e., sensors at particular positions 512).
- the measured environmental signals may be analyzed using a lowpass or a bandpass filter that excludes extraneous signals or noise.
- the measured environmental signals from sensors 510 may be analyzed as a function of time to determine a probable location 514 of an impulse on portal 112 (such as someone knocking on portal 112). This analysis may be based on a propagation velocity of sound waves on portal 112.
- the analysis may use a Green's function to determine the environmental signals at any given sensor based on the impulse at location 514. As was the case with the previously described correction for the mechanical transfer function, this analysis may be inverted to determine a strength or magnitude of the impulse (such as a peak amplitude of the impulse). This may allow the environmental condition (in this example, someone knocking on portal 112) by comparing the corrected environmental signals to historical measurements or a baseline. In particular, an increase in the environmental signals relative to the baseline may indicate the presence of the environmental condition.
- sensors 510 may detect a signature for noteworthy activity.
- sensors 510 may detect the sounds associated with: picking or drilling a lock, kicking in a door, knocking on the door, breaking glass, prying with a crowbar (or other breaking-and-entering noises).
- a knock profile in a history of knocking sounds
- delivery of a package may be identified. This may allow electronic device 110-1 to notify a user of electronic device 110-1 that the delivery has arrived. Alternatively, criminals often test doors to see if they are locked. This anomalous activity may be detected, such as if it is at a time of day when no one is present at a residential, commercial or industrial space.
- instances of electronic device 110-1 at one location (such as a home) or in a neighborhood (or multiple buildings on a corporate campus) report similar events during a time interval (such as an hour, several hours or consecutive days), one or more of the electronic devices or a central server in
- electronic device 110-1 may activate a light near or in proximity to portal 112 to deter a potential criminal.
- electronic device 110-1 is used to monitor pets entering via a so-called 'doggie door.' [0069]
- the combination of time, location, activity on nearby sites, and the activity signature may allow regular portal activity to be distinguished from anomalous portal activity that can represent real security risks. For example, an activity signature for drilling a door lock may raise alarms.
- a server in communication with the electronic device queries a database of service orders for a building maintenance schedule and determines that a worker was likely to be drilling and working on a door at that time, the server may notify a staff member or security guard to double check the portal instead of immediately notifying the authorities.
- the server may notify the authorities directly and immediately. Note the activity signatures may be recorded in, and compared against, a historical database of activities, which includes: time, location, frequency of occurrence, etc.
- sensors 510 shown in FIG. 5 is for purposes of illustration. In other embodiments, different configurations or topologies are used. For example, a star topology may be used, with one electronic device and many one-to-one or one-to-hub connections to sensors 510. In another embodiment, serial or chain-type of communication is used between the instances of the electronic device and/or the multiple sensors. In any of these embodiments, the sensors and/or the instances of the electronic device may be arranged in a mesh network in which the communication involves hoping of packets from one electronic device or sensor to an adjacent electronic device or sensor.
- the communication may be wireless, wired, and/or via vibrations on portal 1 12 (e.g., an acoustic transducer in the electronic device may transmit or receive information via the vibrations, such as those within or outside of the range of human hearing).
- an acoustic transducer in the electronic device may transmit or receive information via the vibrations, such as those within or outside of the range of human hearing).
- positions 512 of sensors 510 may be provided by a user when the user installs sensors 510 on portal 112. However, in other embodiments positions 512 are determined, at least in part, using a local positioning system and/or a Global Positioning System. (Thus, in some embodiments the electronic device includes a position sensor.) More generally, positions 512 of sensors 510 (and/or multiple instances of the electronic device) may be determined using triangulation or trilateration. For example, each one of sensors 510 may transmit a signal in a round-robin fashion, and the time of flight to a remainder of sensors 510 may be measured so that positions 512 can be determined.
- the environmental condition may be used to guide remedial action. Depending on the environmental condition, this may include providing an alert or an alarm.
- the environmental condition may also be used to modify another environmental condition in the external environment. For example, when a door or window is opened, a switch in the electronic device may selectively electrically couple or decouple another electronic device (such as the regulator device) from a power source. In this way, a regulator device (such as a heater, an air conditioner, an air filter, etc.) may be selectively activated. Alternatively or additionally, the regulation may be related to a medical condition of the user.
- the regulation may evolve or change as a function of time or with the identified environmental condition, which may allow the electronic device to dynamically respond to or control the other environmental condition.
- FIG. 6 presents a drawing illustrating communication within electronic device 110-1 (FIG. 1) during method 400 (FIG. 4).
- interface circuit 122-1 optionally receives measurements (meas.) 610 from electronic device 110-2, which are transmitted by electronic device 1 10-2 when it detects displacement of a portal. These measurements are provided to integrated circuit 120-1.
- sensor mechanism 1 18-1 performs measurements 612 associated with
- integrated circuit 120-1 analyzes 614 measurements 610 and/or 612. This analysis may optionally involve the use of one or more conversion tables 616, which may be received from memory 618 or from another external device (such as electronic device 136) via interface circuit 122-1.
- integrated circuit 120-1 provides results 620 of analysis 614 (such as the identified environmental condition) to interface circuit 122-1, and interface circuit 122-1 communicates results 620 to another electronic device, such as electronic device 136.
- the electronic device may be mounted near the portal.
- the electronic device may be mounted on: a wall, a cabinet, the ground/floor, an enclosure, and/or near the portal.
