  • Publication number: 20240150896
    Abstract: A high-speed, uniform and high-quality surface treatment apparatus is described. The surface treatment apparatus includes a fixed hollow cylindrical chamber body and a rotatable polygonal prism inside the chamber body. Several flat-substrate holders are symmetrically disposed on the prism surface. The substrate holders revolve as the prism rotates. On the fixed chamber wall, several gas inlet channels, pumping channels and processing units are installed according to the symmetric configuration of the substrate holders. Then, as the substrate holders revolve, the surface treatment processes will occur periodically, including the injection of gas reactants into, the activation of gases in, and the pumping of after-reaction gases out of the processing spaces, defined by the substrate holders and the chamber wall. The substrates will therefore undergo many cycles of periodic surface treatment processes.

    Abstract: A motor controller comprises a switch circuit and a control unit. The switch circuit is coupled to a motor for driving the motor. The control unit is configured to generate a control signal to control the switch circuit. The motor controller is configured to generate a current signal and a voltage signal. When a current phase of the current signal is at a predetermined crossing phase, the motor controller calculates a difference value between the current phase of the current signal and a voltage phase of the voltage signal, where the motor controller is configured to control the difference value. The motor controller may stabilize the motor and avoid noise by modulating the difference value. The motor controller may modulate the difference value, such that the difference value is equal to a predetermined phase difference.

  • Publication number: 20230245685
    Abstract: A screen is manipulated to display content whose reflection is not captured by a sensor. In an embodiment, the screen inserts a black frame between screen content frames, displaying the black frame during a particular time. A sensor captures a video frame during the particular time. The video frame does not include a screen reflection and is considered a clean frame. In another embodiment, the screen displays screen content with a particular polarization during a particular time. A sensor captures a video frame with another polarization during the same time. The polarizations are selected such that the sensor is unable to capture screen reflections. The video frame is considered a clean frame. The clean frame is used to generate a masking frame, which is applied to target video frames to remove screen reflection. A modified target video, including the reflection-removed target video frame, and/or the clean frame itself, is generated.
