  • Publication number: 20130038717
    Abstract: A method and apparatus for identifying a position of a platform. Features are identified in a series of images generated by a camera system associated with the platform while the platform is moving. A shift in a perspective of the camera system is identified from a shift in a position of the features in the series of images. A change in the position of the platform is identified based on the shift in the perspective.

  • Publication number: 20120071294
    Abstract: A drive device for a hybrid vehicle is provided with an engine and a motor generator. A one-way clutch is provided between the engine and the motor generator. Power is transmitted from the engine to the motor generator, while power from the motor generator to the engine is blocked. As a result, the electric motor can be operated without operating the engine. Furthermore, a torque converter is connected to the motor generator, and the engine is connected to the torque converter via a starting clutch. As a result, if a one-way clutch is provided, the motor generator can serve as a starter motor.

  • Publication number: 20110123369
    Abstract: Provided is a displacement amplifying device which uses Pascal's principle and is insusceptible to temperature change. A main body (1) is provided with an accommodation space (11) for accommodating a medium (2) therein. The medium (2) is provided with a fluid (21) with a positive thermal expansion coefficient and a movable body (22) with a negative thermal expansion coefficient. The movable body (22) is displaced according to the movement of the fluid (21). The medium (2) is provided with a small-area first movable surface (23) and a large-area second movable surface (24). The displacement of one of the first movable surface (23) and the second movable surface (24) is transmitted to the other via the medium (2). In the displacement amplifying device, even if the volume of the fluid (21) is changed by the temperature change of the medium (2), the amount of change of the volume of the medium (2) as a whole can be kept low by the volume change of the movable body (22).

  • Patent number: 7244919
    Abstract: A semiconductor integrated circuit device is provided which has a plurality of photo detector circuits and a plurality of processing elements. Each of the photo detector circuits includes a comparing circuit, which compares an output of a photo detector element with a reference voltage. A/D conversion is performed by counting the elapsed time until the output of the photo detector element drops below the reference voltage, and a level of the reference voltage as a function of time to be applied to the comparing circuit and time intervals of the counting are uniquely determined based on given quantization intervals of an amount of current generated by the photo detector element. In addition, the photo detector elements may be reset locally based on the result of the corresponding processing element.

  • Patent number: 7186363
    Abstract: A holder integrated type base board made of synthetic resin integrally molded with a plurality of holders for inserting LEDs on a front face side of a base board main body and a mold therefore. The mold includes a first mold for molding a back face side of the base board main body and a second mold opposed to the first mold for molding the front face side of the base body main body. In addition, the mold includes a holder molding cavity provided at the second mold which is constituted by an insert die capable of being inserted into and detached from the second mold main body. When it is necessary to correct a position of a portion of the holder in a trially fabricated base board, a position of an LED inserting hole in the base board can simply be corrected by drawing the insert die for molding the holder from the mold main body and interchanging the insert die with a new insert die. As such, an entire first mold does not have to be reproduced.
