  • Publication number: 20140088816
    Abstract: Provided is a tire air pressure monitoring device capable of accurately determining the wheel position of a transmitter. The tire air pressure monitoring device comprises: a transmitter installed on each wheel for transmitting detected air pressure information via a wireless signal; a rotational position detection mechanism disposed on the vehicle body side which detects the rotational position of each wheel and also outputs rotational position information to a communications line at prescribed time intervals; and a vehicle body side rotation position estimation mechanism that estimates the rotational position (i.e., number of teeth) at the time of transmission by the transmitters, on the basis of the reception information for the wireless signal from the transmitters and the rotation position information for the wheels input via the communications line.

  • Publication number: 20140076040
    Abstract: A tire pressure monitoring system controller is provided that comprises a rotational position calculation unit that detects a rotational position for each wheel when a wireless signal including a specific sensor ID has been transmitted; a wheel position determination unit that acquires the rotational position of each wheel a plurality of times and accumulates rotational position data for each wheel, and determines the wheel position corresponding to the rotational position data with the least degree of dispersion among all the rotation position data as the wheel position of a transmitter corresponding to the sensor ID; and a rotational position detection inhibition unit that inhibits the detection of the rotational position of each wheel by the rotational position calculation unit when braking control that controls a wheel cylinder pressure of the wheels is being executed.

  • Publication number: 20130169428
    Abstract: When the difference between the first rotating period determined based on detection by the G sensor and the second rotating period Ta determined based on the detected value of the wheel velocity sensor is equal to or smaller than the prescribed value, the rotational position of each wheel corresponding to the wireless signal transmitted at the prescribed rotational position is adopted in determining the wheel position; when the difference is over the prescribed value, the rotational position of each wheel corresponding to the wireless signal transmitted at the rotational position different from the rotational position is not used in determining the wheel position.

  • Patent number: 5769333
    Abstract: A system including a method and an apparatus is disclosed for effectively separating a foamed heat-insulating material, such as insulated wall sections from used refrigeration equipment, into a foaming gas and a heat-insulating resin without any alteration and recovering them. A peeling portion for peeling a foamed heat-insulating material from a composite material containing the foamed heat-insulating material is included in a crusher provided with a high speed rotor having a plurality of hammers and a casing surrounding the rotor. A sorting portion is provided for sorting the foamed heat-insulating material with a tilting type wind force sorter having a limited tilting angle and a limited height of a wind tunnel. A pulverizing portion is provided for pulverizing the sorted foamed heat-insulating material and for separating a foaming gas therefrom. A condensing portion is provided for cooling and liquefying the separated foaming gas.
