Abstract: A wireless receiver is activated periodically to measure the level of received signals. It measures the average received level over a plurality of the activation periods, and enables the supply of power to receiver circuitry dependent on the measured average value. In one embodiment the power is enabled if an increase in the average value is detected which is greater than a predetermined margin. The average value may be measured in a sliding or stepped window. In another embodiment the power is enabled if the level in an activation period exceeds the average value by a predetermined margin.

Abstract: A thermal interface material (130) facilitates heat transfer between an integrated circuit device (120) and a thermally conductive device (140). According to an example embodiment, a thermal interface material (130) includes carbon nanotube material that enhances the thermal conductivity thereof. The interface material (130) flows between an integrated circuit device (120) and a thermally conductive device (140). The carbon nanotube material conducts heat from the integrated circuit device (120) to the thermally conductive device (140).
