  • Publication number: 20100219769
    Abstract: A high voltage generation circuit for laser puncture in which the voltage for laser puncture can be boosted up to the laser oscillation level in a short time with low power loss. The high voltage generation circuit (21) drives a laser unit section (26) for puncturing the skin by oscillating laser light. In the high voltage generation circuit (21), a capacitor (25) is charged to supply power to the laser unit section (26). A booster circuit section (24) supplies a current to the capacitor (25), and a voltage measuring section (27) measures the voltage of the capacitor (25). A control section (28) controls the booster circuit section (24) based on an instruction from a user or the voltage of the capacitor (25) to start precharge of the capacitor (25) with a first current value at a first timing, and to start main charge of the capacitor (25) with a second current value higher than the first current value at a second timing later than the first timing.

  • Publication number: 20100191147
    Abstract: A piercing device and a blood inspection device that have increased safety. The piercing device (111) has a piercing button (113) placed on the front surface of a first case (112a), a base (114) being a piecing opening provided projecting from the front surface of the first case (112a), and a laser emission device (115) received in the first case (112a). First safety means (117) prevents emission of a laser beam (115a) to the outside when the first case (112a) and a second case (112b) are superposed on each other. When the base (114) is depressed after the second case (112b) is moved from the superposed state where the second case (112b) is superposed on the first case (112a) to a non-superposed state where the second case (112b) is not, a switch (114b) detects the depression of the base (114) and second safety means (118) to enable depression of the piercing button (113).

  • Publication number: 20090071736
    Abstract: A vehicle control system calculates driver-required wheel torque, correction wheel torque to stabilize vehicle motion, required output shaft torque, alternator base torque, target engine torque and alternator torque to realize the output shaft torque. The required output shaft torque is required to realize vehicle motion, and the alternator base torque is required to maintain amounts of electric power in batteries. In order to realize the torque including wide band frequency torque, a torque division unit divides the sum of the torque into each torque actuator response frequency torque. Therefore, the target alternator torque is calculated by the alternator base torque to maintain electric power in batteries and high frequency band torque required by vehicle motion control.

  • Patent number: 7477760
    Abstract: An on-vehicle camera captures an image of an outside visual scene that is outside of a vehicle and outputs image data of the captured image. A wheel speed sensor outputs a measurement signal, which corresponds to a moving speed of the vehicle. An ECU determines a state of the vehicle based on the measurement signal of the wheel speed sensor and an optical flow of a predetermined point of the captured image, which is captured during traveling of the vehicle. The optical flow of the predetermined point is obtained based on the image data of the captured image.

  • Publication number: 20080249689
    Abstract: A vehicle control system estimates the vibration states of tires by using a vehicle vibration model that is separated into a vehicle body vibration model, a chassis vibration model, and a tire vibration model with high precision. The tire vibration model in the vehicle vibration model is formed of a rear wheel tire vibration model, a front wheel tire vibration model, and a virtual coupling element vibration model that virtually couples the rear wheel tire vibration model and the front wheel tire vibration model. Influence of the vibration state that is conducted between the front wheel tires and the rear wheel tires is considered while the tire vibration model and the chassis vibration model are separated from each other, thereby making it possible to estimate the vibrations that occur in the front wheel tires and the rear wheel tires.

  • Patent number: 7328097
    Abstract: While a driving torque TD outputted to a driving shaft via an AT from an engine is detected, a road-surface transmitting torque Td_tire is detected based on rotation speeds Vwdr, Vwdl of vehicle driving wheels, a vehicle body speed Vd, and driving torques Tdr, Tdl, all of which are previously detected. The driving torque TD and the road-surface transmitting torque Td_tire are then compared to each other. When TD>Td_tire, the driving torque from an engine is controlled so as to decrease a value of (TD?Td_tire). The vibrations of individual vehicle parts are thereby decreased.
