  • Patent number: 10755441
    Abstract: A geometric camera calibration system includes an extrinsic iterative closest point (ICP) device that generates an estimated extrinsic matrix by adjusting an initial extrinsic matrix according to first 3D points in camera coordinates; and an intrinsic ICP device that receives 3D points in chessboard coordinates and accordingly generates an error metric between the 3D points in chessboard coordinates and predetermined second reference 3D points. The extrinsic ICP device performs ICP operation to minimize difference between the 3D points in camera coordinates and predetermined first reference 3D points. A current intrinsic matrix is then outputted as an updated intrinsic matrix if a current error metric is not greater than a previous error metric.

  • Patent number: 8076918
    Abstract: A multi-phase driving circuit includes a single-phase pulse-width modulation (PWM) controller, a number of drivers, and a number of switch circuits connected to the number of drivers correspondingly. The single-phase PWM controller is configured for providing a single-phase PWM signal. Each of the number of drivers receives the single-phase PWM signal and adjusts a phase of the single-phase PWM signal to output an adjusted PWM signal. Each of the number of drivers also outputs a driving signal. Each of the number of switch circuits receives the adjusted PWM signal and the driving signal from a driver. Each of the number of switch circuits generates a driving voltage controlled by the driving signal and adjusts a phase of the driving voltage controlled by the adjusted PWM signal and then outputs the adjusted driving voltage, so as to make the number of switch circuits output a multi-phase driving voltage to a load.

  • Patent number: 8050061
    Abstract: A control circuit for a switching power supply (SPS) includes power input and output interfaces, a relay, a relay driving circuit, a microprocessor, and an alternating current/directing current (AC/DC) converter. The power input interface receives an external alternating current (AC) power signal, and transmits the AC power signal to the SPS via the power output interface. The AC/DC converter transforms the AC power signal into a direct current (DC) power signal to supply for the relay, the relay driving circuit, and the microprocessor. When a computer is turned on, the microprocessor sends a first control signal to control the relay driving circuit to drive the relay to connect the power input and output interfaces. When the computer is turned off, the microprocessor sends a second control signal to control the relay driving circuit to drive the relay to cut off connection between the power input and output interfaces.
