Abstract: A device, method, and non-transitory computer readable medium for automatic detection of ritual travel is described. The device includes a processing circuitry configured to determine a relative location and an angle of travel of a user device relative to a central landmark, a first endpoint, and a second endpoint; detect an initial lap around the central landmark based on the relative location and the angle of travel; detect a number of laps taken around the central landmark and a pace of the number of laps; detect a route of travel between the first endpoint and the second endpoint; and provide instructions for completion of ritual travel based on the number of laps taken around the central landmark and the route of travel between the first endpoint and the second endpoint.

Abstract: A smart oqal includes a first loop; a second loop; and a smart pack attached to at least one of the first and second loops. The smart pack is located to not be visible when the oqal is worn on a head of a user, and the smart pack includes at least one sensor for detecting a parameter associated with the head of the user.

Abstract: The method for compressive sensing (CS) and reconstruction of ultra-wideband (UWB) channels includes building four practically-based dictionaries related to the antenna angles of transmission and angles of arrival that enhance the sparsity of UWB signals. The dictionaries account for the practical effects of the channel, such as pulse dispersion and the unavoidable effects of the antenna. Utilizing the practically-based dictionaries CS is able to reconstruct the UWB signals more efficiently with reasonable complexity. In addition to waveform reconstruction, the dictionaries are used for channel estimation. The CS method can be used with either a single-shot full profile correlator or a Rake receiver. The Rake receiver employs CS in adjusting its parameters to take advantage of the energy available in the strongest propagation paths.
