  • Patent number: 8490479
    Abstract: A valve for inflating tires of tired wheels associable with a transducer provided with electronic sensors for detection and transmission of certain operating parameters of the tire. The valve is arranged for being mounted on a rim of a wheel for vehicles so that the valve projects outside the rim and the transducer is positioned within a chamber delimited by the tire and by the rim. The valve includes signaling units which, once the valve has been mounted, are visible from the outside of the wheel. The signaling units are correlated univocally with the orientation of the transducer, and are arranged for indicating the position assumed by the transducer inside said chamber.

  • Patent number: 8482395
    Abstract: A system and method for detecting a rotation of the vehicle tires between different wheel locations. The method carried out by the system involves obtaining and storing TPM sensor identification numbers and their corresponding tire locations. Next, the system checks the sensors periodically to determine if any of the sensors have changed tire location. Based on that change, the system determines if a tire rotation has occurred; for example, by matching changes in sensor positions with known tire rotation patterns. This approach allows the system to detect and record a tire rotation, as well as to take some automated action, such as subsequently notifying the vehicle owner when the next scheduled tire rotation is due.

  • Patent number: 8474312
    Abstract: A tire pressure monitor enables the TPMS (Tire Pressure Monitoring System) in a tire to detect and send a tire pressure signal from an air faucet to the outer side of the wheel rim by an antenna connecting line, and uses an insulation sleeve to isolate an electrical transmission between the air faucet and an external air faucet so that the whole external air faucet becomes an insulating and independent transmitting antenna which can be unaffected by the serious shield from the wheel rim or steel wire annulus. Therefore, the tire pressure can be measured directly by the tire pressure detector inside of the tire and the transmitting signal can be sent accurately to the receiver in the vehicle in order to enhance the reliability of measuring tire pressure and driving safety.

  • Patent number: 8464580
    Abstract: An apparatus to maintain optimal air pressure in a tire of a vehicle may use centrifugal force to compress air which may be delivered to the tire when the tire has low air pressure. The necessary centrifugal force to compress air may be achieved through the rotation of the tire itself. A weight may be disposed, in a chamber, near the center of rotation of a tire. The weight may be held in place with a spring or similar device. As the tire rotates, the weight may be forced outward, compressing air present in the cylinder. If the air pressure within the tire is low, the weight will compress air from inside the cylinder into the tire. The apparatus may act autonomously to add air to a low pressure tire, as opposed to simply notifying the driver that tire pressure is low.

  • Patent number: 8138905
    Abstract: A tire pressure warning device having a detection circuit is mounted to an inflation valve on every tire of a car to implement tire pressure detection. First, a microprocessing controller in the detection circuit sends a tire location ID assigned to every tire to a signal receiving circuit provided in a dashboard of the car. Then, the microprocessing controller detects a tire pressure value of the corresponding tire and uses the detected tire pressure value as a standard pressure point for the tire. Thereafter, the microprocessing controller keeps detecting the tire pressure value of the tire. When a detected new tire pressure value is higher or lower than the standard pressure point by a preset percentage, a wireless RF is transmitted to the signal receiving circuit for the latter to identify the tire with high or low tire pressure and emit an alarm while displaying the tire pressure value.

  • Patent number: 8130091
    Abstract: A tire pressure detecting apparatus has a micro-controller, a detecting module and a transceiver. The detecting module is electronically connected to the micro-controller and has a tire pressure detecting unit controlled by the micro-controller to detect a tire pressure inside a tire. The transceiver is electronically connected to the micro-controller, transmits a high frequency signal corresponding to detected characteristic tire parameters from the detecting module to a monitoring system inside a car and receives an external high frequency signal sent from external tire pressure detecting apparatus for the micro-controller, with the micro-controller temporarily delaying sending of the high frequency signal until a waiting time has expired to prevent signal collision between the high frequency signal and the external high frequency signal.

  • Publication number: 20120031180
    Abstract: An apparatus to maintain optimal air pressure in a tire of a vehicle may use centrifugal force to compress air which may be delivered to the tire when the tire has low air pressure. The necessary centrifugal force to compress air may be achieved through the rotation of the tire itself. A weight may be disposed, in a chamber, near the center of rotation of a tire. The weight may be held in place with a spring or similar device. As the tire rotates, the weight may be forced outward, compressing air present in the cylinder. If the air pressure within the tire is low, the weight will compress air from inside the cylinder into the tire. The apparatus may act autonomously to add air to a low pressure tire, as opposed to simply notifying the driver that tire pressure is low.

  • Publication number: 20120017672
    Abstract: Provided is a tire pressure sensor (TPS) of a tire pressure monitoring system (TPMS). The TPS includes a detachable and angle-adjustable tire valve coupled to the front side of a tire pressure sensor housing. A holder bracket having a tire valve insertion hole is at the front side, and an insertion head inserted into the valve insertion hole is at an end of the tire valve. Accordingly, the angle of the tire valve is freely controlled, allowing compatible use regardless of the shape or size of wheels of cars and commercial vehicles. Thus, manufacturing costs can be greatly reduced, thereby obtaining superior competitiveness over competitors' products. Furthermore, air leakage through a wheel valve hole can be effectively prevented against high speed rotation and inertia motion caused by the high speed rotation during the driving of a vehicle.

  • Publication number: 20120000545
    Abstract: A digital tire pressure gauge has a housing having a first and a second end. A port at the first end of the housing is adapted to engage with and open a needle valve of a tire valve stem. The gauge also includes a pressure sensor and a processor in electronic communication with the pressure sensor. A bleed valve is disposed in the housing and a bleed lever is in contact engagement with the bleed valve. When the port is coupled to the tire valve stem, in a first operational mode, the bleed valve is closed and an air pressure measurement is obtained. In a second operational mode, pressing the bleed lever causes the bleed valve to open and to allow air to be bled out from the tire via the pressure gauge.
