    Abstract: An acoustic system, which may be ultrasonic, operates in a power efficient idle mode thereby reducing the power consumption required by high frequency sampling and processing. While in idle mode, an acoustic receiver device operates with an idle sampling rate that is lower than the full sampling rate used during full operational mode, but is capable of receiving a wake-up signal from the associated acoustic transmitter. When the wake-up signal is received, the acoustic receiver switches to full operational mode by increasing the sampling rate and enables full processing. The acoustic system may be used in, e.g., an ultrasonic pointing device, location beacons, in peer-to-peer communications between devices, as well as gesture detection.

    Abstract: A mobile wireless telecommunication system includes base stations of a first type operating according to a first air interface, and base stations of a second type operating according to a second air interface. Methods and apparatus are provided for handing over a mobile station in the system from a first base station, which is of the first type, to a second base station, which is of the second type. A communications link is established over the first air interface between the mobile station and the first base station. Data are received from the mobile station responsive to a signal received by the mobile station over the second air interface from the second base station, substantially without breaking the communications link with the first base station. The mobile station is handed over from the first to the second base station responsive to the data received therefrom.
