Abstract: A method of localizing the location of a received signal from a tire pressure sensor includes sending an AM identification signal. The AM signal is adjusted for speed such that the frequency of the signal equals a constant multiplied by the speed of the vehicle. Each of the tire locations on a vehicle have an expected sequence of black-out points in the signal received by a receiver at any point on the vehicle. That is, given a particular vehicle design, the AM signal described above would be received at a receiver with an expected sequence of received peaks and black-out points. Since the frequency of the signal is adjusted for speed, the received signal will accurately allow the location of black-out points to be utilized to identify the tire location for a particular signal.

Abstract: A pressure regulation assembly of a fuel supply includes a receptacle, an inlet connectable to the fuel supply and in fluid communication with the receptacle, an outlet in fluid communication with the receptacle, and a pressure regulator mounted in the receptacle to selectively open fluid communication between the inlet and the outlet. The receptacle includes a first surface surrounding an axis, and a second surface surrounding the axis and the first surface to provide a void between the first surface and the second surface. The pressure regulator extends into the void between the first surface of the receptacle and the second surface of the receptacle and includes a third surface surrounding the axis and a fourth surface surrounding the axis and the third surface. A first seal engages the first surface of the receptacle and the third surface of the pressure regulator. A second seal engages the second surface of the receptacle and the fourth surface of the pressure regulator.

Abstract: A method for controlling valve actuation comprises the steps of communicating at least one dithering signal to preload the valve. An event signal is then communicated. The dithering signal is altered based on the cycle time for the valve. The preferred application is for camless engine valve control.

Abstract: A fuel injector control circuit reduces the number of gates required by arranging high side and low side gates in a matrix. Each coil is selectively activated by activating a unique pair of a high side gate and a low side gate, thus reducing the total number of gates required.
