Abstract: A SAW-based humidity sensor apparatus with integrated signal conditioning on the same substrate. A micro-electronic circuit can be processed at a silicon substrate to obtain on-chip signal conditioning internally and the silicon substrate can be covered with a protective layer of, for example, silicon nitride. Surface acoustic wave media (e.g., a ZnO film) can be coated on top of the protective layer. A humidity sensitive film and two sets of interdigital transducers can then be deposited on the surface acoustic wave media. The humidity sensitive film absorbs moisture and changes the receiving frequency at the two sets of interdigital transducers. The output from the two sets of interdigital transducers can be processed by the micro-electronic circuit, which eliminates common mode noise and generates an output signal proportional to the humidity value tested.

Abstract: A piezoelectric vibrator of a vibration gyro vibrates in response to a drive voltage Vdrv input into a drive electrode, and when deformed by a Coriolis force, generates detection voltages Vagc, between which a potential difference corresponds to the deformation, at detection electrodes. An AGC circuit outputs a drive voltage Vdrv while performing automatic gain control so that the detection voltages Vagc have a given amplitude. A phase inversion circuit and a BTL amplifier circuit output a BTL voltage Vbtl, whose phase is opposite to the detection voltage Vagc and whose amplitude has been increased, to the detection electrodes via detection resistances. The AGC circuit reduces the detection voltages Vagc in order to prevent the drive voltage Vdrv from exceeding a design upper limit value Vdrv.

Abstract: Electric Machines (i.e., electric motors or generators) convert electricity to mechanical work (or vice versa) by applying mechanical power to the shaft of the electric machine or extracting mechanical power form the shaft of the electric machine. This restricts the electrical characteristics, such as frequency or voltage, to the movement of the shaft of the electric machine in accordance to electric machine theory. In some cases, it is desired to perform electromechanical conversion from unorthodox movement, such as pulsating movement, slow movement, or low power movement. In many cases this is not possible with even electronic control without a transmission to convert the mechanical power to a compatible motion.
