  • Publication number: 20200124676
    Abstract: A remaining battery energy estimation device according to an embodiment includes a current corrector, an SOC calculator, a voltage estimator, an SOC correction amount determiner, and a current error estimator. The current corrector determines a corrected current value on the basis of a current value and a current correction amount of a storage battery. The SOC calculator calculates an estimated SOC value of the storage battery on the basis of the corrected current value and an SOC correction amount. The voltage estimator determines an estimated voltage value of the storage battery on the basis of a temperature value of the storage battery, the corrected current value, and the estimated SOC value. The SOC correction amount determiner determines the SOC correction amount on the basis of a comparison between a voltage value of the storage battery and the estimated voltage value. The current error estimator determines the current correction amount on the basis of the SOC correction amount.

  • Patent number: 7486409
    Abstract: In a sensor head, parallel rays or approximately parallel rays are generated by a pair of condenser lenses that reciprocate according to vibrations of a collimate lens and a tuning fork, and go out from a light port. To the light port, a lens holder in which an objective lens is supported is detachably attached. The light from the light port is processed to measurement beams that are condensed by the objective lens to a predetermined position.

  • Patent number: 7191087
    Abstract: A sensor controller is disclosed which transmits large-capacity data such as waveform data and image data within a short time (in rapid cycles, for example) and makes possible various collaborative operations using the transmitted data. A control unit includes a programmable logic circuit and a CPU to control the operation of the sensor controller. A unit connector can be used to connect other sensor controllers. An inter-unit path constitutes a signal transmission path between the control unit and the unit connector and includes a sensing data transmission path between the programmable logic circuit and the unit connector. In the case where another sensor controller is connected to the unit connector, the sensing data can be transmitted between the programmable logic circuit of the local sensor controller and the programmable logic circuit of the particular another sensor controller.
