  • Patent number: 10958897
    Abstract: Various examples with respect to visual depth sensing with accurate and full-range depth fusion and sensing are described. A control circuit of an apparatus receives a plurality of sensor signals that are heterogeneous in type from a plurality of sensors. The control circuit generates first depth-related information of a scene and second depth-related information of the scene based on the plurality of sensor signals. The control circuit then fuses the first depth-related information and the second depth-related information to generate a fused depth map of the scene.

  • Patent number: 10917628
    Abstract: Various examples with respect to infrared (IR) patter characteristics for stereo matching are described. A control circuit of an apparatus controls an IR projector to project a patterned IR light. In response, the control circuit receives first data of a left image of a scene from a first camera and second data of a right image of the scene from a second camera. The control circuit then performs stereo matching of the left image and the right image to generate a depth map of the scene. The patterned IR light satisfies one or more characteristic requirements.

  • Patent number: 9647492
    Abstract: A DC uninterruptible power supply system includes plural uninterruptible power supply devices, each of which includes a power cord, a battery module, a voltage detecting circuit, a current detecting circuit, and a control unit. When the voltage detecting circuit detects that a voltage at the power cord is lower than a first preset value, the control unit controls the battery module to output electrical power to the power cord. When the current detecting circuit detects that current of another uninterruptible power supply device is smaller than a second preset value, the control unit controls a switch to permit current flow to the another uninterruptible power supply device.

  • Patent number: 9472952
    Abstract: A battery module includes a plurality of battery units, each of which supplies electrical power to a load through a respective linear regulator. In a method for managing supply of electrical power by the battery module, a number of battery units that supply electrical power to the load is controlled according to magnitude of a current required by the load, so as to reduce power loss in the linear regulators.

  • Patent number: 9285434
    Abstract: A direct current (dc) uninterruptible power system is disclosed. The dc-based uninterruptible power system includes a multiplexer, a battery unit, a linear regulator, a switch-transistor, a voltage comparator and micro controller. The multiplexer receives a first control signal, a first reference voltage and a second reference voltage and outputs a control voltage according to the first control signal. The switch-transistor has a body diode and the body diode has a conduction voltage. When the dc-based uninterruptible power system is non-discharge mode, the switch-transistor is switched-off and the linear regulator receives the first reference voltage, so that the subtraction of the output voltage and the power-supply voltage is smaller than the conduction voltage to cutoff the body diode.
