Abstract: A hybrid powertrain system and method includes a prime mover driving a generator/motor to produce an AC power output. The AC power output is applied to a rectifier which is controlled to transform the applied AC power to DC power to supply a DC Power bus at a selected voltage and current. An energy storage device is also connected to the DC power bus and the current flow between the energy storage device and the DC power bus is monitored and compared to preselected values and the results of that comparison are used to alter the operation of the rectifier to increase or decrease, as needed, the current provided to the DC power bus as electrical loads on the DC power bus change.

Abstract: A system and method are disclosed for determining the mechanical angular position of a rotating member of a prime mover which is connected, directly, or indirectly, to an electric machine, such as a permanent magnet synchronous machine or an induction machine. The electrical angular position of the rotor of the electric machine is determined by a sensorless AC motor control system, such as a Field Oriented Control System or back EMF control system, and is used in turn to determine the mechanical angular position of the rotating member.

Abstract: A method of starting and apparatus for starting a multiphase electrical machine is disclosed. The aim is to reduce oscillatory pulsation in torque generated by the motor and inrush current that occurs shortly after start-up. The starting method comprises the steps of first connecting at least one, but less than all, of a plurality of windings to a respective phase-shifted supply voltage at a controlled point in the supply phase. Then, after a controlled delay following the first connection, connecting the or each remaining winding of the machine a respective phase-shifted supply voltage. The invention has particular application to multiphase (most usually, 3-phase) motors. However, it can also be applied to other electrical machines, such as generators and transformers. The method can be performed at initial start-up or, in the case of application to a motor, at Y-delta switchover.

Abstract: A window lock with an automatic latch retention mechanism and an associated method of securing adjustable frame members of a window are provided. The lock generally includes a housing that can be secured to a first window frame member, a latch member slidably mounted in the housing, a rotatably handle configured to actuate the latch member, and a retention mechanism configured to automatically retain the latch member in the retracted position until the first and second window frame members are relatively adjusted to a closed configuration. The lock can automatically adjust to a locked configuration when the window is closed and remain in an unlocked configuration while being adjusted. The rotatable handle, which can be used to retract the latch member, is configured to provide an indication of the configuration of the lock so that a user can easily identify whether the lock is locked or unlocked.
