Abstract: An apparatus and method for determining the position of a ring magnet fixed to a rotating device includes locating the ring magnet proximate to a sensor that is sensitive to magnetic polarities. The ring magnet includes a plurality of magnetic pole pairs of opposite magnetic polarities, having at least one pole pair larger than at least three other pole pairs. The sensor produces an output signal for each pole pair that represents a period when a pole pair is detected by the sensor as the ring magnet is rotated by the device. The output signals from the sensor are coupled to a digital circuit that differentiates the three smaller pole pairs from the at least one larger pole pair to determine the position of the ring magnet.

Abstract: A process and apparatus for cooling a heat generating component of a vehicle comprises a first pump switchable between a normal demand mode and a high demand mode. Coolant is pumped from the first pump through a cooling loop between a heat dissipating device and the heat generating component at a normal demand flowrate in the normal demand mode. Switching the first pump to the high demand mode diverts the coolant to a second pump. The second pump pumping the coolant through the cooling loop at a high demand flowrate.
