Abstract: A data processing device including a processor and a memory interface, the processor being configured to control the refreshing of a memory by the steps of: periodically forming an estimate of a current rate of decay of a memory and updating an accumulated level of decay of the memory in dependence on the estimated current rate of decay; and causing the memory interface to refresh the memory when the accumulated level of decay exceeds a predetermined threshold. The estimate may be based on a measurement of ambient temperature.

Abstract: An apparatus includes an antenna array including at least a first antenna element and a second antenna element separated by a first distance. The apparatus receives a wireless advertising message, having a known bit pattern, via the first and second antenna elements. The apparatus samples a first portion of the known bit pattern from the wireless advertising message received via the first antenna element, and samples a second portion of the known bit pattern from the wireless advertising message received via the second antenna element, and determines a phase difference between the received wireless advertising message at each of the first and second antenna elements by correlating the first sampled portion and the second sampled portion to the known bit pattern. The apparatus then determines an angle of arrival (AoA) of the wireless advertising message based at least in part on the phase difference and the first difference.

Abstract: A power detector measures RF power delivered into a first load of uncertain impedance. A reference power meter measures power of a reference signal to a second load of known impedance. The reference power meter measures voltage across the second load; measures a current through the second load; and multiplies the measured voltage by the measured current to generate a reference power signal proportional to power delivered to the second load. A measurement power meter measures power of a signal to the first load. The measurement power meter measures voltage across the first load; measures current through the first load; and multiplies the measured voltage by the measured current to generate a measured power signal proportional to power delivered to the first load. The power detector includes a processor to calculate power delivered to the second load, and to generate a power delivered to the first load.

Abstract: A method and apparatus for harvesting information from a plurality of radio frequency (RF) sources. In one example, a collector device receives RF signals from the RF sources to produce the harvesting information. The collector device also determines environmental context information describing a physical environment of the collector device as the RF signals were being received, and a position of the collector device where the RF signals where received. The collector device then associates the environmental context information with the harvesting information and the position, and transmits the harvesting information and position with the associated environmental context information to a server device. The server device may then compute positioning information biased to different environmental contexts. This biased positioning information may then be utilized by other collector devices having similar environmental contexts to better estimate their respective locations.
