  • Publication number: 20200247319
    Abstract: A surrounding vehicle display device includes: a surrounding information detection device that obtains information on surroundings of a host vehicle; and a vehicle speed sensor that detects a vehicle speed of the host vehicle. The surrounding vehicle display device includes a controller that uses the information obtained by the surrounding information detection device to generate a virtual image that indicates the surroundings of the host vehicle as being viewed from above the host vehicle and a display displays the virtual image. The controller makes a display region of at least a rear region around the host vehicle on the virtual image wide when the vehicle speed detected by the vehicle speed sensor is higher than a low vehicle speed.

  • Patent number: 9485808
    Abstract: A sheet heater includes a first fiber layer, a second fiber layer distanced from the first fiber layer, a third fiber layer disposed between the first and second fiber layers, and a controller operable to control heat generation. The first fiber layer is constituted of first conductive portions and first non-conductive portions. The second fiber layer is constituted of second conductive portions and second non-conductive portions. The third fiber layer includes functional layers each constituted of connecting yarns and non-functional layers arranged to insulate each of the functional layers from others of the functional layers. The controller applies voltage between the first and second conductive portions to heat the connecting yarns. According to the heater, a desired temperature distribution can be created on the heater by applying the voltage selectively to one target segment composed of the first conductive portion, the functional layer and the second conductive portion.

  • Patent number: 9258848
    Abstract: A matrix-patterned cloth includes: first and second fiber layers including mutually isolated first and second conductors, respectively; an intermediate fiber layer between the first and second fiber layers; conductive connecting yarns connecting one of the first conductors and one of the second conductors, wherein, when a pressure is applied to the matrix-patterned cloth, each connecting yarn bends so that a position of contact between the connecting yarn and the first or second conductor changes depending on how large the pressure is; a selector; and a heating controller or a resistance measuring unit. The selector scans and sequentially selects one of the first conductors and one of the second conductors. The heating controller applies voltage to intersecting areas where the selected first and second conductors intersect each other via the first and second conductors. The resistance measuring unit measures electric resistances of the intersecting areas via the first and second conductors.

  • Publication number: 20150203121
    Abstract: Heart rates of the driver are recorded at a deceleration start time when a vehicle in a travelling state starts to decelerate and stop. The heart rates within a predetermined period recorded before the deceleration start time by the biological information record unit are referred to, and a pre-deceleration heart rate which is a representative value of the referred heart rates is extracted. Furthermore, the heart rates within a predetermined period recorded after the deceleration start time by the biological information record unit are referred to and a post-deceleration heart rate which is a representative value of the referred heart rates is extracted. Then, the pre-deceleration biological information and the post-deceleration biological information extracted by the biological information extraction unit are compared with each other to estimate the steady state of the driver after deceleration.

  • Publication number: 20030078879
    Abstract: There is provided a claim management system capable of enabling a customer utilizing a credit card settlement to determine a financial institution for settlement and a settlement method after the time of purchasing goods. When the customer selects deferred determination of a settlement financial institution and a settlement scheme in utilizing the credit settlement, the claim management system independent of individual financial institutions manages a claim vested in the customer. The claim management system periodically inquires the customer of the determination of a settlement financial institution and a settlement scheme and when the customer selects further deferment of the determination, requests the customer to pay interest.

  • Publication number: 20020162330
    Abstract: The invention relates to a thermal cycle of power generating system. A current closed thermal cycle used in electric power stations requires both heat source and cooling source. The heat source temperature needs to be much higher than that of the cooling source. In order to raise the heat source temperature, electric power stations consume fuel, causing environmental pollution and fuel shortage.

  • Patent number: 6314354
    Abstract: An automatic lane following system for a vehicle is adapted to control the direction of a moving vehicle along a predetermined path. An associated controller estimates the vehicle's lateral position in relation to the lane markings (usually the white painted lines). An optical sub-system or a video camera or equivalent sensor is mounted on a vehicle and used to detect the lane markings. An actuator coupled to the steering mechanism is used to control the steering position of the front road wheels in response to a steering signal from a controller. An interruption switch is closed to enable the steering system actuator. An interruption switch actuator is displaceable between a rest or stored position in which the interruption switch is open and an operable position in which the interruption switch is closed.
