Abstract: An acoustic tracking system for determining a position of an object is provided that includes one or more receivers that detect an object based on an acoustic signal transmitted by one or more transmitters. The system also includes a processing component that determines a relative position of the detected object with respect to the one or more receivers and the one or more transmitters and selects at least three pairs of receivers and transmitters. Each selected pair includes a receiver from the one or more receivers and a transmitter from the one or more transmitters. The processing component also determines a position of the detected object using the selected at least three pairs of receivers and transmitters.

Abstract: In an aspect of the disclosure, an apparatus for wireless communication is provided. The apparatus may include several detectors, each of which may be configured to detect a signal received by a corresponding antenna of several antennas. The apparatus may include a processing system configured to detect a remote apparatus based on outputs from the detectors. The apparatus may include several modem radio frequency chips each including a corresponding detector of the several detectors, and a modem baseband chip including the processing system. The processing system may be configured to allow at most one of the detectors to output a detection declaration to the processing system at a time. The processing system may be configured to send a power-down command to and disconnect from each of the detectors that does not detect the signal from a corresponding antenna of the several antennas.

Abstract: A method includes accessing signal data descriptive of a transmission sequence and pre-determined values associated with the transmission sequence. The signal data and the pre-determined values may be stored in a memory. The method includes transmitting a signal from a speaker of an electronic device according to the transmission sequence. The method includes generating a frame based on one or more signals received at a microphone of the electronic device. The one or more signals include an echo signal associated with the transmitted signal. The method includes processing the frame using the pre-determined values to produce an output frame in which a contribution associated with the echo signal is reduced.

Abstract: A mobile communication device equipped for proximity detection may include a transmitter that emits a periodic ultrasound signal, a receiver that detects the periodic ultrasound signal, an intra-frame filter that filters the detected periodic ultrasound signal based on a frame length of the detected periodic ultrasound signal, and a detector that determines a power level of the filtered periodic ultrasound signal to detect if the receiver is located in an undesirable location.
