  • Patent number: 10724850
    Abstract: To enable measurement of a displacement at a predetermined position in the case in which a measurement object remains stationary and also in the case in which the measurement object moves. A light projector and a scanning part are controlled to cause measurement light to sequentially irradiate different positions of the measurement object in a case in which a scanning mode is selected. On the other hand, the light projector and the scanning part are controlled to cause the measurement light to irradiate the same positions of the measurement object in a case in which a line mode is selected. The displacement of the measurement object is measured on the basis of a received-light quantity distribution output from a light receiver.

  • Publication number: 20200233037
    Abstract: According to one embodiment, an evaluation device for an energy storage device includes first processing circuitry and second processing circuitry. The first processing circuitry acquires data items including an amount of charge and a voltage value measured in a measurement period from the energy storage device, the energy storage device being charge-discharge-controlled according to charge-discharge command values. The second processing circuitry generates a representative data item of voltage values for amounts of charge, based on the data items acquired for the measurement period; and evaluates a degradation state of the energy storage device, based on a relative change between a plurality of the representative data items corresponding to a plurality of the measurement periods.

  • Patent number: 10677584
    Abstract: To enable short-time measurement of a displacement at a predetermined position of a measurement object even when the position or the posture of the measurement object is changed. During operation of a displacement measuring apparatus, the position and the posture of a measurement object are determined by using position correction information, and a measurement position is corrected. The corrected measurement position is irradiated with measurement light. The measurement light that is emitted to and is reflected back from the measurement position is received by a light receiver. The light receiver outputs a received-light quantity distribution for displacement measurement, and a displacement at the measurement position is measured on the basis of the received-light quantity distribution.
