  • Patent number: 11911891
    Abstract: An actuator system that picks up workpieces aims to shorten tact time and to reduce damages to workpieces. The actuator system includes an actuator that picks up a workpiece, an external force detection sensor that detects a physical quantity that is correlated with an external force that is applied to the workpiece, a head unit that is connected to the actuator and the external force detection sensor without a communication network, the head unit being configured to control the actuator based on a sensing result from the external force detection sensor when a pickup request signal that is a signal requesting pickup of the workpiece is received, and a control device that is connected to the head unit over the communication network, the control device being configured to transmit the pickup request signal to the head unit.

  • Publication number: 20240027624
    Abstract: A ranging device includes: a frequency distribution generation unit that generates a frequency distribution of a light reception count value counted in each bin period; a frequency distribution holding unit that holds the frequency distribution generated by the frequency distribution generation unit; and a phase setting unit that sets a phase of start timings of the bin periods with respect to periodic light emission timings to an object. In a case where a first frequency distribution acquired by a first phase in a first period is held in the frequency distribution holding unit, and then a second frequency distribution acquired by a second phase in a second period next to the first period is held in the frequency distribution holding unit, at least a part of the first frequency distribution is erased from the frequency distribution holding unit until the holding of the second frequency distribution is completed.

Each of the M detection elements includes a detection pixel configured to detect incidence of a photon and a generation circuit configured to generate a readout request and data based on the detection of the photon in the detection pixel. The readout circuit is configured to receive the readout request and the data from each of the M detection elements. The control pulse providing circuit is configured to provide a control pulse to the M detection elements and the readout circuit. The readout circuit determines the generation circuit corresponding to the readout request and a generation timing at which the readout request is generated, based on a counter value of the time counter and the number of delay cycles included in the data corresponding to the received readout request.
