  • Patent number: 11519709
    Abstract: A position sensor is configured to use a Wiegand wire, position magnet(s) and a reset magnet in which changes in polarization of the Wiegand wire caused by the position magnet(s) can be reset by the reset magnet. The position magnet(s), which can move in relation to the Wiegand wire, can have relatively stronger magnetic flux densities, and the reset magnet, which can be fixed in relation to the Wiegand wire, can have a relatively weaker magnetic flux density. When the position magnet(s) are proximal the Wiegand wire, the relatively stronger position magnet(s) overcome the reset magnet to cause a change in polarization of the Wiegand wire which produces an electrical pulse which can be counted. However, when the position magnet(s) become distal to the Wiegand wire, the relatively weaker reset magnet can reset the polarization of the Wiegand wire to prepare for a next count.

  • Patent number: 10545032
    Abstract: An angle sensor includes a first to a fourth detection unit and an angle detection unit. Each of the first to the fourth detection unit generates two detection signals. The first to the fourth detection unit are arranged in a positional relationship that establishes predetermined phase relationships among the detection signals they generate. The angle detection unit performs operations using the detection signals to generate a first and a second signal in which an error component corresponding to a fifth or higher-order harmonic and an error component corresponding to a harmonic of the order other than the fifth order are lower than those in the detection signals. The angle detection unit then calculates a detected angle value on the basis of the first and the second signal.

  • Patent number: 10475678
    Abstract: Apparatus and method for monitoring wafer charges are proposed. A conductive pin, a conductive spring and a conductive line are configured in series to connect the backside surface of the wafer and the sample conductor so that the backside surface of the wafer and the surface of the sample conductor have identical charge density. Hence, by using a static electricity sensor positioned close to the surface of the sample conductor, the charges on the wafer may be monitored. Note that the charges appeared on the frontside surface of the wafer induces charges on the backside surface of the wafer. As usual, the sample conductor is a sheet conductor and properly insulated from the surrounding environment. As usual, the sample conductor and the static electricity sensor are positioned outside the chamber where the wafer is placed and processed, so as to simplify the apparatus inside the chamber and reduce the contamination risk.
