Abstract: A torque control system for a vehicle having a plurality of wheels, wherein at least two of the wheels are arranged to be driven by separate electric motors, the system comprising a master controller arranged to monitor the torque generated by at least one of the electric motors and upon a determination that the torque produced by the at least one electric motor is reduced as a result of a predetermined condition the master controller is arranged to adjust the torque generated in the at least one electric motor and/or another electric motor so that the torque generated by the at least one electric motor and the another electric motor are substantially the same.

Abstract: An assembly that incorporates an expandable strap for use in electrical impedance tomography includes a strap adapted to be mounted onto the body of a patient. A plurality of electrodes is mounted on the strap and spaced equidistantly along the length of the strap. An electrical connector is mounted on the strap, and electrical traces extend from each electrode to the connector. Preferably, the strap is made of a substantially inelastic material. In one embodiment, the strap has a serpentine shape to allow for uniform expansion.
