Patent ID: 7648436

Claim:
An orthotics system comprising: The application has been amended as follows: a drive motor; a first cam device, including a first cam, coupled to the drive motor; a second cam device, including a second cam mounted out-of-phase with respect to the first cam, coupled to the drive motor; a first belt conterminous with the first cam device, wherein, in operation, the first cam device deflects the first belt to a degree that is dependent upon a position and shape of the first cam; a second belt conterminous with the second cam device, wherein, in operation, the second cam device deflects the second belt to a degree that is dependent upon a position and shape of the second cam; a first brake assembly engaging a first worm-gear-to-sprocket attachment, the first worm-gear-to-sprocket attachment engaging a first sprocket, the first sprocket engaging the first belt wherein, in operation, the first brake assembly brakes the first belt by braking the first worm-gear-to-sprocket attachment; a second brake assembly engaging a second worm-gear-to-sprocket attachment, the second worm-gear-to-sprocket attachment engaging a second sprocket, the second sprocket engaging the second belt, wherein, in operation, the second brake assembly brakes the second belt by braking the second worm-gear-to-sprocket attachment; an output assembly conterminous with the first belt and the second belt, wherein, in operation, the output assembly is coupled to a load, the load is moved by the first belt when the first belt moves in a first direction, and the load is moved by the second belt when the second belt moves in the first direction, wherein deflection of the first belt and deflection of the second belt are phased to provide substantially continuous output torque.
