Abstract: In one embodiment an apparatus can include a plurality of magnetic material layers. In one embodiment, an apparatus can include one or more electrically insulating layer, wherein the plurality of magnetic material layers and the one or more electrically insulating layer define a stacked up structure, wherein an electrically insulating layer of the one or more electrically insulating layer includes thermally conductive dielectric material.

Abstract: Methods and systems detect short circuits in an electrical system, such as a dynamic braking grid of a vehicle. The methods and system measure a characteristic of a current that is conducted through one or more resistive elements of an electrical system. The current is supplied to the electrical system from a power source as an applied voltage. A resistance change signal representative of a change in one or more electrical resistances of the one or more resistive elements is determined The resistance change signal can be based at least in part on a difference between the characteristic of the current that is measured and a low pass filtered value of one or more of the characteristic of the current that is measured or the applied voltage supplied by the power source. A short circuit event is identified based at least in part on the resistance change signal.

Abstract: This invention relates to protective devices for placement under the heel of a vehicle driver's footwear. In particular the invention discloses a protector pad device that elevates the back of the driver's boot or shoe above the floor of the vehicle to prevent the heel from contacting or remaining in any mud, snow and water located on the vehicle floor. The device is releasably attached to the vehicle floor or mat with mechanically adhesive strips. The device has a extended contoured depression to guide the driver's foot into proper placement for safety and ease of pivotting of the foot from accelerator pedal to brake pedal during the operation of the vehicle. The device is thickened on the side that is to be located away from the center of the vehicle in order to provide a more level platform for the boot's heel in the usual situation where the vehicle's floor slopes down from the center of the vehicle out toward the driver's side door.
