Abstract:
PROBLEM TO BE SOLVED: To provide a battery charge/discharge system. SOLUTION: The battery charge/discharge system includes a regenerative cable and a plurality of charge/discharge controllers. The charge/discharge controllers are made to correspond to respective batteries. When the battery is in a discharge mode, a discharge current outputted by the battery flows through the regenerative cable via the charge/discharge controller. When the battery charge/discharge system operates, the regenerative cable has a regenerative voltage and the regenerative voltage is a DC voltage. COPYRIGHT: (C)2011,JPO&INPIT

PROBLEM TO BE SOLVED: To provide a battery charging and discharging device, and a method. SOLUTION: The battery charging and discharging device includes a power supply and a plurality of charging and discharging modules. Each charging and discharging module is provided with a current limit transistor, a current limit resistor, a charging control unit, and a discharging control unit. Both of the charging control unit and the discharging control unit are battery voltage tracking type. When the charging and discharging modules charge the battery, the voltage crossing two end parts of the current limit transistor and the current limit resistor connected in series is limited to a fixed value by the charging control unit. When the battery is discharged, the voltage crossing two end parts of the current limit transistor and the current limit resistor connected in series is limited to a fixed value by the discharging control unit. The discharging control unit feeds back discharge energy to the power supply from the battery. COPYRIGHT: (C)2011,JPO&INPIT
Abstract:
An optical sensing system and a color analyzer with the same are provided to improve accuracy and redundancy due to directionality of a liquid crystal display panel by using a telecentric optical system. An optical sensing system includes a condensing device(420), an optical uniformization device(430), an optical receiver(440), and a signal processing body. The condensing device condenses only a ray having a radial angle less than a predetermined value among rays irradiated from a measuring target area to one rear condensing surface. The optical uniformization device diffuses the ray condensed on the condensing surface. The optical receiver receives a part of the rays transmitted from the optical uniformization device to a rear direction and determines a received optical spectrum range. The signal processing body calculates optical and color characteristics corresponding to an optical signal received by the optical receiver.
