摘要： 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.

摘要： A method for performing a soft handoff, including establishing a first control channel via a network between a first BSC and a first BTS. The method also includes establishing a second control channel via the network between a second BSC and a second BTS. A call between a mobile station (MS) and the first BTS is established, and while the call continues an indication is sent to the first BSC that the MS has received a signal from the second BTS. In response to the indication, a trigger is conveyed from the first BSC to the second BTS, and, in response to receiving the trigger at the second BTS, further traffic associated with the call is directed between the MS, the second BTS, and the first BSC, without conveying the further traffic through the second BSC.

摘要： A double-acting brake assembly comprising a drum mounted on a rotary shaft, a brake band with looped ends surrounding the drum, and actuator means to displace ends of the band toward one another, is provided with a mounting bracket having spaced reaction surfaces which cooperate with the ends of the band to permit the band to wrap onto the drum for braking the drum when rotating in either the clockwise or counterclockwise directions. The reaction surfaces extend widthwise of the band adjacent the periphery of the drum, and a pair of guide surfaces extend alongside the ends of the band for aligning the band axially of the drum. In one embodiment, the bracket has an L-shaped crosssection with a flange overlying the drum and the reaction and guide surfaces are provided by the edges of an aperture in the flange. Other forms of brackets, including a bracket combined with a dust cover, are also disclosed. A preferred form of actuator includes a flexible sheath and cable assembly having one end connected to an operating lever and the other end connected to the ends of the band. The actuator draws the looped ends of the band together to engage the band with the drum, but allows lost motion between the end loops and the reaction surfaces of the mounting bracket. The end loops are free to move against either reaction surface, so that no matter which direction the drum is rotating, it will be the end loop at the leading end of the band which engages a reaction surface, and the trailing end of the band will in every case be free to wrap about the drum to provide a servo or self-energizing braking action. This will provide self-energizing braking on both forward and reverse rotation of the drum.
