Abstract: Methods and apparatus for determining whether a vehicle tyre pressure check has been carried out, comprising: receiving from a pressure reader module a request for tyre pressure data indicative of a the pressure of a gas retained within a pneumatic tyre; storing, by a pressure check register, data indicating that the request for tyre pressure data was received; transmitting, by a transmitter to an apparatus, an indication confirming whether a tyre pressure check has been carried out based on whether the request for tyre pressure data was received; receiving, at the apparatus from a plurality of tyre pressure sensing modules, a plurality of indications of whether a tyre pressure reader has been used on each of the plurality of tyre pressure sensing modules to check a corresponding tyre pressure; and determining, by a pressure check confirmer, whether a vehicle tyre pressure check has been carried out based on the received plurality of indications.

Abstract: A sensing device (200) for fitting at an inner surface of a wheel (222) and configured to abut a wheel hub (224) when the wheel (222) is fitted to a vehicle, the device (200) comprising: a movement sensor (602) for detecting movement of the device away from the wheel hub (224), the movement sensor (602) being located within a sensor housing (202); and a temperature sensor (606) configured to measure a temperature indicative of brake temperature.

Abstract: A wheel loosening sensor configured to detect loosening of a wheel of a vehicle, the wheel loosening sensor including: a water tight housing that is permanently sealed, wherein at least two electrical terminals are exposed at an exterior of the water tight housing. Within the water tight housing, there is a transmitter and a battery, the transmitter being configured to receive electrical power from the battery and to transmit a signal when the at least two electrical terminals are disconnected. The water tight housing including an electrically conductive element biased away from the at least two electrical terminals and configured to electrically connect the two electrical terminals when the bias is overcome.

Abstract: A device and method for detecting wheel loss from a vehicle when the vehicle is in motion. The device (1) is provided with a housing (11) configured for, in use, mounting the device to a wheel (3) such that the device (1) abuts a wheel hub (5) of an axle to which the wheel is attached. A detector (6) is provided for detecting a proximity of the device (1) to the wheel hub (5), and a transmitter (8) is provided for sending an alarm signal in the event that the detector (6) detects that the device (1) is no longer in proximity to the wheel hub (5). In this way, if the wheel starts to become detached from the wheel hub, the detector (1) detects this and can send an alarm to, for example, a receiver unit in the drivers cabin, allowing the driver to take appropriate steps.
