  • Patent number: 8220324
    Abstract: Identification information for identifying a tire, a tire inner pressure and a tire inner temperature are sent to a tire checking device from a first electronic device provided within a tire and measured results are shown on a display. Groove depth data from a depth meter are also received by the tire checking device and shown on the display. The tire checking device stores received management information such as a tire inner pressure, a tire inner temperature, a groove depth and so on in a memory with associating them with each tire. The stored management information is extracted by a control unit if required and shown on the display. Therefore, a tire inner pressure and a tire inner temperature are detected automatically and groove depth data are stored with being associated with each tire, and thereby the tire inner pressure, the tire inner temperature and the groove depth data can be displayed.

  • Patent number: 7696902
    Abstract: A tire sensor device comprising sensor modules 20A to 20D, each comprising a sensor, a communication module having a communication function and a power regenerating circuit, and an antenna; and a base station comprising an internal communication device for communication with the sensor modules 20A to 20D, an information processing device for processing tire information signals from the sensor modules, an external communication device for communicating with a car control device 40 on the car body side and a power source. The sensor modules 20A to 20D and the base station 30 are arranged in the tire and constitute an intra-tire LAN. Tire information signals transmitted from the sensor modules 20A to 20D are processed by the base station 30 and transmitted to the car control device 40 so that appropriate tire information can be obtained and the size and power consumption of the sensor device can be reduced.

  • Patent number: 7668695
    Abstract: The present invention includes a sensor malfunction determination unit 207 detects the pressure value corresponding to a signal outputted by a pressure sensor 101 capable of measuring the internal pressure of a pneumatic tire 10. When the detected pressure value is decreasing along the time axis, the sensor malfunction determination unit 207 determines that the pressure sensor 101 is not malfunctioning.

  • Publication number: 20070158436
    Abstract: An RFID tag-incorporating bar code label having sufficiently high durability even when the label is attached to a tire and capable of reliable communication with a reader. A dipole antenna type RFID tag 14 is interposed and fixed between a first sheet member 11 whose front surface is printed with a bar code 13 and a second sheet member 12 having an adhesive layer formed on the rear surface, thus fabricating an RFID tag-incorporating bar code label 10 having an RFID tag buried in the central portion of a bar code sheet 17. The label 10 is bonded to a tire. Therefore, the position of the RFID tag 14 can be easily specified. Due to the existence of the second sheet member 12, the RFID tag 14 can be spaced apart from a rubber member and a steel product constituting the tire by a predetermined distance.
