  • Publication number: 20080283601
    Abstract: In a mechanism for attaching to a cart an RFID tag used for transmitting and receiving data to and from an RFID reader/writer, a holding pocket retains the RFID tag. The orientation of the pocket is kept constant in such a manner that a surface of the RFID tag from which data can be read highly accurately faces an antenna for the RFID reader/writer while keeping the distance between the RFID tag and the antenna within a certain range regardless of the transfer direction of the cart.

  • Publication number: 20080191848
    Abstract: When a detector sensor such as an infrared sensor or the like detects a palette or cart mounting a product, the output of the radio wave from the antenna of the reader/writer is set to a minimum value. Then, the radio wave output value is gradually increased from the minimum value until an RFID tag can be read/written. After the RFID tag can be read/written, a target process such as the reading/writing of the RFID tag or the like is performed and the process is terminated. After the process is terminated, the radio wave output is returned to the minimum value.

  • Publication number: 20080174433
    Abstract: A tag is attached to each piece of a set of goods mounted on a palette, and a tag storing the quantity of goods that should be mounted on the palette is also attached. A reader/writer counts the number of tags attached to all of the goods, reads quantity information of the tags attached to the palette, and determines whether the two are equal or not.

  • Publication number: 20030118891
    Abstract: In an ECU, a coolant fan performs cooling operation such that a control DUTY value is limited by a control DUTY value according to tolerable noise level of the cooling fan based on a vehicle speed in a case in which the temperature in the high-voltage battery is lower than a predetermined limitation for highest temperature. In a case in which the temperature in the high-voltage battery is higher than the predetermined limitation for highest temperature, the cooling fan performs the cooling operation by using an energy storage device cooling operation requirement value and an IPU cooling operation requirement value such that performance in the high-voltage battery is not affected.

  • Patent number: 6437538
    Abstract: An apparatus for measuring battery voltage is provided that can detect battery voltage with high accuracy, and also can be miniaturized with cost and noise reduced. The apparatus comprises: a capacitor which is charged to the voltage of each module, switches which connect and disconnect this capacitor and the module, a voltage follower which outputs the voltage across the capacitor, and switches which connect and disconnect the voltage follower and the capacitor. For the aforementioned switches, photo MOSFETs are used. Furthermore, to prevent discharge from the capacitor, a voltage follower is installed. Therefore, by using not a complicated circuit but inexpensive and simple elements, a low cost and miniaturized apparatus for measuring battery voltage is realized.

  • Patent number: 6255826
    Abstract: The present invention provides a battery voltage measuring device capable of immediately detecting a breakage in the voltage measuring line in a battery voltage measuring device that detects the battery voltage. In blocks formed by connecting a plurality of secondary batteries in series, voltage sensors that detect the voltage of each block are respectively provided. In addition, before these voltage sensors noise filters are provided, and in addition, a measuring line breakage detecting resistor for detecting a breakage in the voltage measuring line is connected in parallel to each block. In a battery voltage measuring device having this type of structure, in the case that the voltage measuring line Q is broken, the voltage values V1 and V2 detected by the voltage sensors 20-1 and 20-2 become voltage values that accompany the resistance ratio of the measuring line breakage detecting resistors 60-1 and 60-2.
