An electric vehicle propulsion system having a motor with first and second electrically isolated windings and a system control unit for controlling the motor, wherein the system control unit includes a first power bridge for driving the first windings and a second power bridge for driving the second windings.

Electric vehicle propulsion system employing AC induction motor control

An apparatus for cooling a switching circuit for an electric vehicle, wherein the switching circuit has at least two switching elements connected in series, includes first and second heat sinks, each having two thermally-conductive planar members forming a passage therebetween for channeling cooling fluid, an inlet port in communication with the passage, and an outlet port in communication with the passage, and a substrate for mounting at least one switching element to each of the first and second heat sinks. An ac terminal connects the switching element attached to the first heat sink in series with the switching element attached to the second heat sink, and inlet and outlet manifolds, coupled to the inlet and outlet ports of the first and second heat sinks, circulate cooling fluid through the passages of the first and second heat sinks to cool the switching elements.

Direct cooled switching module for electric vehicle propulsion system

An assay device for detecting the presence of analytes in an unknown sample including a reaction system wherein storage reservoirs containing reagent are fluidly connected to a track containing the sample. An actuation mechanism forces the reagent from the reservoirs and into the track where it mixes the reagents together and then with the sample at a first flow rate. The mechanism then reduces the force on the reagent to allow a second flow rate less then the first flow rate to force the reagent and sample mixture through the track so that reaction can occur, whereby a determination as to whether the target analyte was present may be made.
