Abstract:
Provided is a tire air pressure transmission device configured to determine the rotational position of the tire air pressure transmission device based on a gravitational acceleration component of a centrifugal acceleration at the time of transmission of the tire air pressure information and to transmit in a wireless signal and at a prescribed cycle, tire air pressure information and tire air pressure transmission device rotational position information.
Abstract:
A tire air pressure transmission device is provided that is configured to set a sampling period or cycle based on a centrifugal acceleration of a wheel in the centrifugal direction, and to detect the value of the gravitational acceleration component of the centrifugal acceleration at each set sampling period.
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.
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.
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. A compressor is provided for compressing the pulverized non-foaming gas portions of the heat-insulating material for reducing the volume thereof. These recovery steps are accomplished without permitting escape of the foaming gas to the outside of the system.
Abstract:
A tire air pressure monitor device is provided for monitoring air pressure in tires using pressure sensors, which are installed in the tire of each wheel. Each wheel has a transmitter for wirelessly transmitting the air pressure information along with a sensor ID when the wheel is at a predetermined rotation position. A vehicle body has a receiver for receiving the wireless signals. A wheel speed sensor is provided on a vehicle body for each wheel to determine the wheel rotation position. A TPMS control unit acquires the wheels rotation position when a wireless signal containing a certain sensor ID is transmitted. The TPMS control unit accumulates wheel rotation position data, and determines the wheel position corresponding to the wheel rotation position data having the smallest degree of dispersion from among the wheel rotation position data as the wheel position for the transmitter corresponding to the sensor ID.
