Abstract: Cycle error correction is performed in an electronic power system to compensate for a difference between an AC grid side frequency and an AC load side frequency. The electronic power system can comprise an electronic power inverter, such as one usable with an uninterruptible power supply. Cycles of signals indicative of the AC grid power and the AC load power are counted and compared to obtain a cycle error value. If the cycle error value exceeds a first value to indicate that AC load side frequency is too high or too low, then compensation is performed to change the AC load side frequency to be closer to the AC grid side frequency. If the cycle error value falls below a second value to indicate that the AC grid side frequency and AC load side frequency are sufficiently close to one another, then the compensation is deactivated.

Abstract: An ignition assembly includes a power converter receiving an alternating current input, including a first capacitor and a second capacitor. The first capacitor and the second capacitor are charged in parallel to a first DC voltage and at a first polarity to discharge in series to an output at a second DC voltage that is greater than the first DC voltage. The second DC voltage is coupled to an ignition gap, and causes the ignition gap to ionize and form a spark. A switch is coupled to the first capacitor and is operable to control the discharge of the first capacitor and the second capacitor. An AC input switch is coupled to the AC input and is operable to control a flow of current from the AC input through the first capacitor and the second capacitor to the output. The flow of AC to the output sustains the ionization of the ignition gap.

Abstract: A method and system controls motion of an armature 112 of a fuel injector 100. The armature moves between an open coil 118 and a close coil 116 of the injector. Acceleration current of a certain polarity is applied to the open coil 118 with the armature disposed at the close coil 116. De-latching current of a polarity opposite of the certain polarity is applied to the close coil 116 to release magnetic latch on the armature thereby accelerating movement of the armature towards the open coil 118. Deceleration current is applied the close coil 116 thereby decelerating the armature prior to reaching the open coil. Latching current of the certain polarity is applied to the open coil 118 prior to or just after impact of the armature 112 with the open coil 118 to magnetically latch the armature to the open coil 118 thereby reducing bounce of the armature at impact.

Abstract: A pedal position sensor provides a redundant pair of output signals that are indicative of the pedal position by providing a pair of shaped plates that are mounted on a pedal shaft. A single magnet generates a magnetic field that is changed depending on a position of at least on plate attached to the pedal shaft. Changes in the magnetic field are sensed by a first and second magnetic field sensor that produce independent outputs indicative of pedal shaft position.

The cover can formed by an overmolding process that encapsulates the circuitry on the upper layer of high temperature substrate or by lamination. The transmission controller can then be attached at a desired location within or on an outer surface of a transmission.
