  • Patent number: 12078542
    Abstract: An optical sensor circuit is provided. In the optical sensor circuit, an output stage circuit transmits a voltage of first and second node to the output line according to a first driving signal. A first sensor is configured to generate a first photocurrent according to a first color light that senses an ambient light, and generate a second photocurrent according to a second color light. A second sensor is configured to generate a third photocurrent according to a third color light, and generate a fourth photocurrent according to the second color light. In a sensing phase, when the first sensor senses the first color light, and the second sensor senses the third color light, the first sensor adjusts a voltage level of the voltage according to the first photocurrent, and the second sensor adjusts the voltage level of the voltage according to the third photocurrent.

  • Patent number: 11983046
    Abstract: A portable information handling system pivots a hinge rotational axis as the hinge rotates housing portions between open and closed positions to manage a gap between the housing portions. For example, the hinge couples a base at a perimeter of one housing portion, the base having a many body that slides on sliding members of the base and that supports a bracket extending inward to couple to another housing portion. A bracket gear engages with a pinion gear included in the main body to translate bracket rotation through the pinion gear to a rack integrated in the base, thereby sliding the main body relative to the base as the housing portions rotate so that the distance between the housing portions adjusts with rotational orientation.
