    摘要： A method in an amplifier, for example, a power amplifier in a wireless transmitter, including monitoring (310) a characteristic of the amplifier during a first active interval of the first set of active intervals, storing (320) the amplifier characteristic monitored during the first active interval of the first set of active intervals, correcting (340) an open-loop control signal to the amplifier based on the stored amplifier characteristic monitored during the first active interval of the first set of active intervals, and providing (350) the corrected control signal during a second active interval of the set of first active intervals subsequent to the first active interval of the set of first active intervals.

    摘要： My invention is a unique component installed onto the ends of torsion springs that adds four additional winding holes and permits the winding and unwinding (tensioning and de-tensioning) of torsion springs in situations where adjacent obstructions would otherwise disallow the normal means of this process while using normal trade tools. Under these limited access conditions, torsion springs that are fitted with the Double Headed Spring Winding Cone would be most desirable when new doors are installed and when old springs on existing doors need replacing.

    摘要： A device (10) for reducing vibration effects on position measurement includes a receiver (12) for providing position signals (13); and a vibration control circuit (18) operative to control position information generation based on the position signals (13), to prevent position information generation during mechanical vibration of the device (10). A method for reducing vibration effects on position measurement includes receiving position signals through a receiver; and controlling position information generation based on the position signals to prevent the position information generation during mechanical vibration of the device.
