Abstract: A method for initialising a tyre monitoring device including a wireless communication interface and tyre monitoring devices and systems using the method are disclosed. The method includes operating the tyre monitoring device in a first mode, in the first mode the tyre monitoring device is only responsive to an initialisation instruction received over the wireless communication interface from the second device; receiving an initialisation instruction over the wireless communication interface while operating in the first mode; and, responsive to the initialisation instruction, operating the tyre monitoring device in a second mode in which the tyre monitoring device is responsive to instructions received over the wireless communication interface. The first mode draws lower power than the second mode so power draw prior to initialisation, for example while storage awaiting use, is reduced.

Abstract: A system for monitoring tire pressure and producing a first signal in the event that a low tire pressure condition has been sensed and a second, different signal in the event that a low tire pressure condition has not been sensed and a third signal in the event that the system is not operable. The system comprises a sensor for each tire and an associated transceiver antenna coil. Each sensor comprises a pressure switch and a circuit that has a first resonant frequency when the pressure switch is in a first state and a second, different resonant frequency when the switch is in a second state. An excited circuit associated with each transceiver antenna coil generates an AC electromagnetic field across the transceiver antenna coil and a detector circuit is operable to demodulate information communicated passively by the sensor that reflects its resonant frequency.

Abstract: A tyre (6) pressure sensor comprises a pressure-sensitive part (8), in particular with a deformable membrane (10), mounted in the centre of the hub (7) of wheel (2), and a transducer part (12) housed in the axle (1) of wheel (2). This arrangement in which the sensor is separated into two mutually rotating parts is nonetheless more practical and simpler than devices in which electric connection is required between a wheel carrying the sensor assembly and the read device. The invention applies in particular to aircraft.

Abstract: A monitoring system for monitoring a first parameter includes a sensor, a receiver and an indicator. The sensor is positioned at a first location and is operable to sense the first parameter. The receiver is positioned at a second location remote from the first location and within proximity to the sensor. The receiver is operable to generate a signal indicative of the first parameter and includes a first inductor, a second inductor and an amplifier having a feedback path. The first inductor and the second inductor are positioned relative to one another to create an electromagnetically coupling between the inductors such that feedback from the coupling is one of either a substantially zero feedback and a negative feedback. The indicator is in communication with the receiver to provide the first parameter to the user. This parameter may include a tire pressure of a tire on a vehicle. The system also includes a tire pressure monitoring system where a sensor is housed within a first housing and a second housing and mounted to a rim of a vehicle. A sensor of the monitoring system also includes an inductor having an inductance L which is positioned relative to a ferrite core. The ferrite core is operable to vary the inductance L of the inductor. The receiver of the system includes an amplifier having a feedback path such that the amplifier is in a waiting non-oscillating mode when the sensor is not electromagnetically coupled to the receiver and in an active oscillating mode when the sensor is electromagnetically coupled to the receiver.

Abstract: In an apparatus for detecting the pressure condition in a pneumatic tire on a vehicle body, a pressure-responsive resonant switching device is mounted on the pneumatic tire and is switchable between a first impedance state, where pressure in the pneumatic tire is within a predetermined normal operating pressure range, and a second impedance state, where the pressure in the pneumatic tire is not within the predetermined normal operating pressure range. An excitation unit is mounted on the vehicle body adjacent to the pneumatic tire. A controller supplies an excitation signal to the excitation unit in order to enable the latter to co-act with the resonant switching device by virtue of mutual induction according to the impedance state of the resonant switching device for inducing current in the resonant switching device as the resonant switching device is moved so as to be proximate with the excitation unit due to rotation of the pneumatic tire relative to the vehicle body. The controller monitors an output signal from the excitation unit and detects the presence of a change in the output signal of the excitation unit due to inducing of the current in the resonant switching device during a complete cycle of rotation of the pneumatic tire to enable the controller to determine the pressure condition in the pneumatic tire.

Abstract: A tire pressure detector for motor vehicles which is to be fastened at the circumference of a wheel rim and comprises an oscillating circuit having coupling coil which cooperates with a stationary receiver coil. In order to increase the minimum air gap between the rotating coupling coil and the stationary receiver coil, the coupling coil, which rotates with the wheel rim, is arranged on a middle limb of a plate-shaped ferrite core. The magnetic coupling for the stationary receiver coil is improved by means of the shape of the ferrite core (23).
