Abstract: A tire pressure sensor with power generator includes a spool having a coil wound therearound. Within the spool is a pole piece. The tire pressure sensor is installed in a wheel that rotates with respect to a brake clamp. The brake clamp includes a magnetic strip that the sensor moves past as the wheel rotates. As the tire pressure sensor moves past the brake clamp, the magnetic strip causes the coil to output an AC voltage signal. A rectifier circuit connected to the coil converts the AC voltage to DC voltage. The DC voltage is stored in a storage capacitor to be used as needed by an air pressure sensing element connected thereto.

Abstract: A device for monitoring at least one parameter for vehicle wheels includes, on each wheel, a detector unit having a transmitter unit that respectively transmits a phase-modulated or frequency-modulated signal to a central evaluation and control unit. Each detector unit transmits, at specific time intervals, a brief signal that contains a uniquely defined identifier. After a wheel is changed, a renewed assignment of the detector unit to the respective wheel positions can be carried out in an assignment mode of the detector unit and of the control unit, by registering a profile of the mean reception power for each detector unit as a function of the angular position of the respective wheel and comparing such signature profile with stored signature information. The comparison can be carried out by cross-correlating the two respectively decisive curves, or by comparing individual values or specific characteristic variables of the profiles.

Abstract: An automatic car tire pressure detecting apparatus constitutes an emission means located at the wheel rim of the tire and a receiving means located at the brake pad. The emission means includes a generator, an emission end and a pressure sensor. The generator has a coil which has a positive and a negative end linked in series with a rectify switch and the emission end. The receiving means includes a magnet located at a corresponding tangent spot of the coil, a receiving end and a microprocessor attached to a display device. When the tire rotates, the magnet continuously cuts the coil to generate electric current to actuate the emission end. The rectify switch determines if the current flowing therethrough is positive. The positive current will be used for actuating the emission end to emit signals which are received by the receiving end thereby the detecting apparatus is able to provide self-generating power supply to transmit signals without an external power supply.

Abstract: A magnetically coupled pressure display system particularly adapted for pneumatic tires of motor vehicles includes pressure transducer coupled for rotating a magnet field source within the tire and an external magneto-optical liquid crystal display attached to or integrally incorporated into the exterior sidewall of the tire for visually indicating pressure within the tire responsive to the orientation of the magnetic field source within the tire. The external display exploits the magneto-optical effects of liquid crystals and can be conformally and permanently attached to the outer tire sidewall surface. Elements (pixels) comprising the display have selective light polarization properties globally determined by direction (orientation) of the magnetic field each experiences, the primary component of which is that provided by the magnetic field source rotated by the pressure transducer within the vehicle tire.

Abstract: A wireless tire inflation pressure measurement device is used to obtain inflation pressure information for a tire of a vehicle and a signal therefrom may be used for determining the location of the tire. An identifier may be associated with the inflation pressure information for each wheel of the vehicle. Tire rotation speed may be determined by amplitude fluctuations of a radio frequency carrier from a radio frequency transmitter rotating with the wheel. Differences in wheel rotation speeds during a turn may be used in determining the location of each tire of the vehicle. An antenna may be placed on each wheel toward the outer perimeter of the wheel and connected to the radio frequency transmitter. A radio frequency identification (RFID) tag and pressure sensor may be used as the wireless tire inflation pressure measurement device and a RFID pickup coil may be provided in each wheel well for pickup of the inflation pressure signals from each RFID tag on a wheel.

Abstract: A tire characteristic monitoring method allows automatic programming of tire position information in a remote tire pressure monitoring system (10). The method includes, from a remotely located exciter (16) using a primary coil (18) to transmit a relatively low frequency signal to a secondary coil (L1) of a tire monitor (12) associated with a tire of a vehicle. The method further includes the step of, at the tire monitor, in response to the relatively low frequency signal, transmitting a relatively high transmitting signal to convey data. The data are received at the exciter and subsequently loaded into a receiving unit (14) of the vehicle.
