  • Sensor comprising gate modulation with inductor to form a resonant circuit
    Patent number: 11211421
    Abstract: A sensor includes a photodiode disposed in a semiconductor material to receive light and convert the light into charge, and a first floating diffusion coupled to the photodiode to receive the charge. A second floating diffusion is coupled to the photodiode to receive the charge, and a first transfer transistor is coupled to transfer the charge from the photodiode into the first floating diffusion. A second transfer transistor is coupled to transfer the charge from the photodiode into the second floating diffusion, and an inductor is coupled between a first gate terminal of the first transfer transistor and a second gate terminal of the second transfer transistor. The inductor, the first gate terminal, and the second gate terminal form a resonant circuit.

  • Fusion of electronic mirror systems and driver monitoring for increased convenience and added safety
    Patent number: 10810966
    Abstract: An apparatus includes an interface and a processor. The interface may be configured to communicate video data to a display. The processor may be configured to receive video frames from a capture device, generate video data for the display in response to the video frames, perform operations to detect an object in the video frames and determine eye position information. The eye position information may be used to determine whether a driver is looking at the display. The processor may be configured to adjust content presented by the display when the driver is looking at the display.
