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 for power management of a wireless device is described. The method comprises supplying a first voltage level to a volatile storage device during a period when the processor is in an operating state; supplying a second voltage level, lower that the first voltage level, to the storage device for retaining data during a period when the processor is in a reduced power state, and determining a value of the second voltage level. The second voltage level is determined by performing a self-test of the storage device to find a minimum second voltage level that gives a number of data errors below a predetermined threshold.

Abstract: A controller (322) for determining the location of speakers (302, 304,...) in a system of speakers configured to play out audio signals received according to a wireless communications protocol. The controller configured is to, for each speaker of the system of speakers, transmit a signal to that speaker comprising an indication of a playout time for playing out an identification sound signal comprising the identification data of that speaker. The controller is configured to receive data indicative of a played out identification sound signal from each speaker as received at least two listening locations (L 1 , L 2 , L 3 , L 4 ), wherein relative positional information about the at least two listening locations is known. For each of the at least two listening locations, the controller determines the locations of the speakers of the speaker system relative to the position of one of the at least two listening locations.
