  • Patent number: 10092866
    Abstract: The present invention describes an assembly of magnets to be coupled to oil filter case to attract ferrous material. Oil filter case [20] takes the shape of a cylinder. Magnet [22] has two poles and one of the poles is coupled to the side of oil filter case [20]. A steel member [24] is provided to couple only the other pole of the magnet [22] with the oil filter case [20]. The steel member [24] comprises a pivot unit [26] that couples the pole of magnet, a pivot extender [28] which couples the pivot unit [26] and a bridge [30] that couples the pivot extender [28] with oil filter case [20]. The magnet assembly directs the magnetic field from outward pole towards the oil filter to create a pseudo horse shoe magnet effect.

  • Patent number: 6803672
    Abstract: A device is disclosed for reducing overheating in a passenger compartment of a parked vehicle. The device has a temperature sensor, a temperature comparator, and a control system in electrical communication with the comparator for controlling the actuation and operation of an existing air conditioner fan within the vehicle. The control system incorporates a power supply management arrangement designed to draw energy in pulses from a battery unit of the vehicle to energize the motor when the temperature in the passenger compartment exceeds a predetermined level, and to cease drawing energy when the temperature falls below the predetermined level.
