  • Publication number: 20220276341
    Abstract: The present disclosure relates to a measurement device, a measurement method, and a program that enable measurement of a distance with high accuracy in a shorter time. A signal for giving an instruction on emission timing to emit a pulse of laser light is generated repeatedly for each predetermined processing cycle, and a count code indicating timing at which a pulse of reflected light that is the laser light reflected by a distance measurement target and returned is received is continuously counted at the time of switching a processing cycle. Then, an instruction on an emission delay value indicating a time for delaying the emission timing from the start of the processing cycle is given to be different for each processing cycle. The present disclosure can be applied to a measurement device that measures a distance.

  • Publication number: 20220236414
    Abstract: The present disclosure relates to a measurement device, a measurement method, and a program that enable measurement in a shorter time. A signal for giving an instruction on emission timing to emit a pulse of laser light is generated in order to output the laser light having the number of pulse emissions of two or more times within a distance measurement range time of one time by setting, as the distance measurement range time, a width of a flight time in which light reciprocates between the measurement device and a distance measurement range representing a fixed distance width including a distance to be measured.

  • Patent number: 8619439
    Abstract: A flyback boost circuit includes an output voltage detection terminal provided to a secondary winding of a transformer of the flyback boost circuit, and configured to detect an output voltage. Prior to the start of a boost operation, current is supplied to a secondary side of the transformer via the output voltage detection terminal to detect a voltage generated at the output voltage detection terminal, to thereby detect an unwired state by determining whether or not there is floating of the output voltage detection terminal or a grounding terminal of the secondary winding of the transformer.
