Abstract: A system for filtering mechanically-induced signal noise from a speed sensor may include a rotating member having at least one target group radially oriented about a center of the rotating member, an inductive speed sensor configured to sense the at least one target group, and two diode pairs each having a first diode and a second diode. The two diode pairs may be operatively connected to the inductive speed sensor and configured to receive a signal having the mechanically-induced signal noise. The system may also include a resistor connecting the diode pairs, a processor connected in parallel with the resistor and configured to receive a signal from the inductive speed sensor. The processor may be configured to receive a signal having reduced signal noise via the diode pairs, and determine a rotational speed of the rotating member based on the signal having reduced signal noise.

Abstract: A variable displacement fuel pump includes a pump body, a barrel disposed within the pump body, at least one piston disposed in the barrel, wherein the at least one piston is configured to reciprocate within the barrel, and an electronic control actuator operatively coupled to the barrel, wherein the control actuator rotates the barrel to a selected barrel angle relative to the at least one piston in response to a desired fuel flow.
