  • Patent number: 10797817
    Abstract: Provided is an optical signal processing device that can operate simultaneously for a plurality of wavelength bands. The optical signal processing device includes a WDM coupler array including a plurality of WDM couplers for separating the C band and the L band for the respective ports; input/output port groups provided for the C band and the L band, respectively; a micro lens array; a diffraction grating; a lens; and a spatial light modulator arranged in this order. The spatial light modulator collects light at different positions for the respective wavelengths, thus allowing all wavelengths to be independently subjected to a phase modulation. Light subjected to the desired phase modulation by the spatial light modulator is reflected and is deflected to have an angle corresponding to any desired port of the input/output port group, and then is optically-coupled to an input/output port depending on the deflection angle.

  • Publication number: 20190322181
    Abstract: The number of opportunities where external charging of a vehicle parked in a residential parking space or a charging station in a predetermined period is available is counted as the number of opportunities, and the number of times of the external charging performed in the opportunities in the same predetermined period is counted as the number of times of charging. The number of times of charging is then divided by the number of opportunities to calculate and store a charging frequency. Since the charging frequency is a ratio of the number of times that the external charging was performed to the number of opportunities where the external charging is available in the predetermined period, the ratio is used as an index that can offer more accurate determination regarding an external charging utilization status. As a result, various processing to promote external charging are executed more properly.

  • Patent number: 10407081
    Abstract: A utilization index IDX is calculated based on one or more parameters (the number of times of charging/the number of trips, total battery charger connection time/total vehicle stop time, total EV traveling distance/total HV traveling distance, total EV traveling time/total HV traveling time, total EV traveling distance/total traveling distance, total EV traveling time/total traveling time, total charge amount/total fuel supply quantity) obtained based on a ratio of an EV traveling utilization level to an HV traveling utilization level or a total traveling utilization level, and the utilization index IDX is stored. Since the utilization index IDX is calculated such that as each parameter is larger, utilization of charging of a battery by a battery charger is performed more sufficiently. Accordingly, the utilization index IDX can be used as an index that offers more accurate determination regarding a utilization status of the battery charging.
