  • Publication number: 20230016671
    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: 20220108611
    Abstract: This invention provides a bidirectional interactive traffic-control management system. The system comprises a road and traffic network information subsystem, an urban traffic control subsystem and a road-users' route guidance subsystem. The first subsystem forms real-time traffic information of all road sections in the digital urban traffic-control road network. The second subsystem generates a real-time optimal signal timing plan for each intersection based on the real-time traffic information of its connecting road sections. The third subsystem generates a real-time optimal route plan based on the real-time travel information of all road-users, the real-time traffic information of all road sections, and the real-time optimal signal timing plan of each intersection of the road network. It then transmits the optimal route plan into a navigator in a mobile device of a road-user or in an on-board-unit of a moving vehicle or via a roadside unit for transmission.

  • Publication number: 20210390983
    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.

  • Publication number: 20210320247
    Abstract: Embodiments of the disclosure provide methods for forming MTJ structures from a film stack disposed on a substrate for MRAM applications and associated MTJ devices. The methods described herein include forming the film properties of material layers from the film stack to create a film stack with a sufficiently high perpendicular magnetic anisotropy (PMA). An iron containing oxide capping layer is utilized to generate the desirable PMA. By utilizing an iron containing oxide capping layer, thickness of the capping layer can be more finely controlled and reliance on boron at the interface of the magnetic storage layer and the capping layer is reduced.
