    Abstract: A position of a mobile communication device is determined by obtaining a first set of candidate signal templates, wherein each candidate signal template in the first set of candidate signal templates corresponds to a respective candidate position of a first set of candidate positions, and wherein magnitude values in each candidate signal template in the first set of candidate signal templates are encoded in accordance with a first magnitude encoding strategy. A first radar echo signal is obtained, and a first test signal is produced by encoding magnitude values of the first radar echo signal in accordance with the first magnitude encoding strategy. The first test signal is correlated with each candidate signal template in the first set of candidate signal templates to obtain a first set of respective correlation results. A second set of candidate positions is produced by using the first correlation results as a basis for selecting fewer than all of the candidate positions from the first set of candidate positions. A second set of candidate signal templates is obtained, wherein each candidate signal template in the second set of candidate signal templates corresponds to a respective one of the candidate positions in the second set of candidate positions, and wherein magnitude values in each candidate signal template in the second set of candidate signal templates are encoded in accordance with a second magnitude encoding strategy that is different from the first magnitude encoding strategy.

    Abstract: Camouflage detection systems and related techniques are provided to improve the detection of camouflaged targets, including targets employing active thermal camouflage techniques. A camouflage detection system includes an imaging system and a logic device configured to communicate with the imaging system and a supplemental sensor system. The imaging system includes an infrared imaging module configured to provide infrared and/or thermal image data of a scene including a camouflaged target. The logic device is configured to receive infrared image data and supplemental sensor data, determine an estimated target spatial profile, and determine one or more target profile anomalies based, at least in part, on the estimated target spatial profile.

    Abstract: Example implementations relate to computing device locations and computing devices having audio components thereon that change operational states. In some examples, a non-transitory computer-readable storage medium can include instructions that when executed cause a processor of an electronic device to determine a default host computing device of a plurality of computing devices, request a location of a first computing device of the plurality of computing devices using a sensor of the default host computing device, and request a location of a second computing device of the plurality of computing devices using the sensor. The instructions when executed can cause the processor to determine a first audio loop potential associated with the first computing device and a second audio loop potential associated with the second computing device, assign the first computing device as an active client and assign the second computing device as an inactive client.
