Shuhei CHIZUWA has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20180334041
    Abstract: Provided are a charging device and a vehicle capable of reducing the amount of noise flowing into a quick-charging facility. The pair of charging lines connecting the quick-charging facility (20) to an onboard battery (30) are referred to as quick-charging lines, and each of these quick-charging lines is provided with a relay (16-1, 16-2). Each relay (16-1, 16-2) is used to switch the current flowing in the respective quick-charging line on and off, the current being switched on during quick-charge and being switched off during normal charging. Each quick-charging line has a Y-capacitor (17) connected thereto closer to a QC port (15) than the respective relay (16-1, 16-2).

  • Publication number: 20180233932
    Abstract: A measurement apparatus includes first and second sensors, first and second processors, a multiplexer, and an A/D converter. The first and second sensors are configured to detect an identical physical quantity, and respectively output analog signals according to the physical quantity. The first processor performs an offset process on an analog signal from the first sensor using a first offset value to output a first analog signal. The second processor performs an offset process on an analog signal from the second sensor using a second offset value, which is different from the first offset value, to output a second analog signal. The A/D converter converts the first analog signal to output a first digital signal when the multiplexer outputs the first analog signal, and converts the second analog signal to output a second digital signal when the multiplexer outputs the second analog signal.
