Abstract: Disclosed herein are system, method, and computer program product embodiments for the detection of human presence in front of a plurality of sensors such as those of speakers and a device with a processor, such as a television. Data gathered from the plurality of sensors may be analyzed by the processor to determine if one or more humans are present proximate to the device. Based on the determined presence or absence of one or more humans, further actions including, inter alia, activating a sleep mode for the one or more humans, shutting off the device in a green mode, or alerting an owner-user to the presence of an intruder can be taken.

Abstract: Disclosed herein are system, method, and computer program product embodiments for detecting human presence in front of a plurality of sensors, such as speaker sensors, and a device with a processor, such as a television. An example method includes varying, during a collection routine, a respective signal strength of one or more of a plurality of transmitters. The example method further includes receiving results of the collection routine in a form of raw data from a plurality of sensors. The example method further includes determining, by at least one processor, a respective geographical position of one or more humans present within a predetermined geographical range of the at least one processor based on the raw data from the plurality of sensors. Subsequently, the example method includes executing an action based on the respective geographical position of the one or more humans.

Abstract: Some embodiments include an apparatus, method, and computer program product for high precision device synchronization of electronic devices in a shared medium. Some embodiments include a first electronic device that utilizes a combination of synchronization techniques to synchronize with a second electronic device. The first electronic device receives a first signal from the second electronic device that includes network-based synchronization data and marker data, and performs network-based synchronization with the second electronic device at a first synchronization accuracy. The first electronic device receives a second signal, and uses the marker data and phase lock synchronization to detect a frequency change of the second signal received, as well as to determine a corresponding time marker. The first electronic device updates a clock of the first electronic device based at least on the corresponding time marker, the network-based synchronization data, and the marker data.
