Abstract: There is provided a method of using an electric machine. To generate torque, electricity is provided to stator coils on a plurality of salient poles of a stator arranged around a rotor having a plurality of salient poles to pull the rotor salient poles in the circumferential direction. To generate electricity, the method comprises rotating the rotor and generating a magnetic field on a magnetizing member. The magnetizing member is arranged coaxially with the rotor and offset from the rotor in the axial direction. The method further comprise conducting the generated magnetic field to the salient poles of the rotating rotor to induce alternating magnetic flux on the stator coils, and recovering electricity generated by the induced alternating magnetic flux from the stator coils. The generated magnetic field does not change its configuration when the rotor rotates except for distances between the closest pairs of rotor salient poles and stator salient poles.

Abstract: A tool for use in affixing an optical component, such as glass, to a liquid crystal display (LCD) using a silicone gel mixture includes, in one embodiment, a unitary metallic platen that is shaped to define a central window. A narrow shelf is defined around the central window to support the optical component during the application of the silicone gel thereon. A upwardly extending partition is formed onto the top surface of the platen around the shelf to retain the optical component fixed in place on the platen during the assembly process. A plurality of identical, spaced apart, upwardly extending standoffs are formed onto the free end of the partition to support the LCD a fixed distance away from the optical component. In this manner, the standoffs ensure that the layer of silicone gel deposited between the optical component and the LCD is uniform in thickness to optimize performance.

Abstract: A method and apparatus for detecting degradation in the cam profile switching system in either bank 2, 3 of a V-engine 1 relies on a comparison of the lambda values in each exhaust bank 4, 5 immediately prior to and subsequent to a cam profile switching event in one of the banks. If there is little or no change after switching, then the apparatus deduces that the switched bank has experienced degradation. The method is easy to calibrate and does not require continuous monitoring of engine behavior.
