<p>A method of sending a transmission from a transmitter unit, particularly a tyre pressure monitoring unit. The method includes initiating the transmission after a variable length delay has elapsed from a reference point in an output signal of a wheel phase angle sensor in the transmitter unit, and selecting the length of the variable delay to compensate for a variable phase delay associated with the output signal. The method provides a reliable technique for processing the output of the wheel phase angle sensor to determine the Angle of Interest and provide correlated transmissions from the wheel mounted unit to a central controller for the purposes of auto-location.</p> |
