摘要： An apparatus includes a rotatably mounted magnetic rotor, a first coil mounted in proximity of the magnetic rotor, the first coil mounted such that, if the coil is flowing with electric current, the magnetic rotor is within immediate proximity of at least part of a magnetic field created by the coil. The apparatus includes a second coil mounted in proximity of the magnetic rotor, the second coil mounted such that, if the coil is flowing with electric current, the magnetic rotor is within immediate proximity of at least part of a magnetic field created by the coil. A current source is coupled to the first coil, for generating an AC signal and applying the AC signal across the first coil whereby an AC output signal develops across the second coil, the AC output signal having a magnitude that varies in relation to the rotational position of the rotor.

摘要： An IC driver mounted on a LCD display package contains a sensor for determining temperature of the LCD cell, and a digital value of the temperature is serially transmitted to a remote microprocessor which determines compensated voltage and sends voltage command data back to the IC driver which produces a drive voltage by a charge pump. A digital code on the LCD cell identifies cell response characteristics and the code is used by the microprocessor to calculate the desired voltage. A ROM in the IC driver stores many bit-mapped images which are selected by the microprocessor for display.
