  • Patent number: 11394400
    Abstract: A data processing method and a data processing apparatus are provided to reduce a bit error rate of a wireless communications system and improve transmission performance of the wireless communications system. The method includes: mapping L to-be-sent bits to L bit locations included in at least one modulation symbol, where the L to-be-sent bits include at least one bit field, a bit in a bit field having a high priority is preferentially mapped to a bit location that is of the at least one modulation symbol and that has a high reliability level, the at least one bit field is at least one of an information bit field, a first parity bit field, and a second parity bit field; and outputting the at least one modulation symbol.

  • Patent number: 11383940
    Abstract: A robotic manipulator for handling a cassette and an automated cassette transport device are disclosed, the device including a mechanical arm (1), an end actuator (2) at an end of the mechanical arm (1) and a vision-based locating assembly (3) on the end actuator (2). On the one hand, the vision-based locating assembly (3) can determine the position of a flange of the cassette, thereby identifying the cassette. In other words, the cassette can be identified based on a feature of the cassette itself. This dispense with a separate locating marker while improving cassette measuring and handling accuracy. On the other hand, transportation of the cassette is allowed by complementary retention of its flange on a recessed surface of the end actuator (2).

  • Patent number: 10197390
    Abstract: A pre-alignment measurement device includes, disposed in a direction of propagation of light, a laser, a first cylindrical lens, a first imaging lens, an illumination diaphragm, a second imaging lens, a second cylindrical lens and a CCD detector. The laser, an object under measurement and the CCD detector are arranged at respective apexes of a triangle formed by the measurement device for pre-alignment. A light beam is emanated by the laser and is transformed into a line beam. The line beam is reflected by the object under measurement and then passes through the second cylindrical lens to form a CCD image which has different horizontal and vertical magnifications, allowing horizontal and vertical resolutions to be matched with horizontal and vertical measuring ranges, respectively. The CCD image contains information of a position and a height of a step defined by the object under measurement and the wafer stage.
