  • VEHICLE DRIVING SUPPORT APPARATUS AND VEHICLE DRIVING SUPPORT PROGRAM
    Publication number: 20190156133
    Abstract: Visual line information unique to a driver is detected from a captured image of the driver, whose visual line is guided to a predetermined position, before starting driving, and visual line information of the driver detected during driving is calibrated by using the detected visual line information unique to the driver as a calibration value.
    Type: Application

  • Semiconductor charge pump circuit and nonvolatile semiconductor memory device
    Patent number: 6747897
    Abstract: A charge pump circuit includes inverters INV1 and INV2. The inverter INV1 receives a clock signal CLK2, and applies a voltage waveform at an immediately previous node to a second end of a capacitor connected to a transistor and to the p-well thereof. The voltage of the capacitor on the side of the control terminal of the transistor, and the voltage waveform at the node, are raised with the same phase timing as the clock signal CLK1. The inverter INV2 receives a clock signal CLK1, and applies a voltage waveform at an immediately previous node to a second end of another capacitor connected to another transistor and to the p-well thereof. The voltage of the another capacitor on the side of the control terminal of the another transistor, and the voltage waveform at the node, are raised with the same phase timing as the clock signal CLK2.
