Abstract: A torque sensor is disclosed. The sensor has a support member for mounting to a rotatable shaft and a flexible electro-conductive member pre-tensioned and mounted to the support. An electrical coil is positioned in electrical communication with the support member and electro-conductive member. A magnetizing system is positioned adjacent the support member. The sensor is passive and operates on energy received from its rotation relative to the stationary magnetizing means. A receiver remotely detects electrical changes from the movement of the flexible member from torque experienced by the rotatable shaft.

Abstract: A drive system suitable for use in a variable transmission with a plurality of rotatable and adjustable disk members, gear means adapted for contact with the plurality of disk members, carriage means for mounting the gear means and configured for axial movement along the axis of a rotatable drive shaft and a rotatable cone adapted for contact with the plurality of disk members, the cone and the conical gear means connected for relative rotation by the plurality of disk members, the disk members being adjustable transversely relative to the axis of rotation for maintaining positive contact with said rotatable cone.
