Patent ID: 7604571

Claim:
An exercise device, comprising: a support surface; at least two position sensors arranged along a sensing plane extending one of generally parallel and obliquely relative to said support surface, said at least two position sensors adapted to detect a presence of a user along said sensing plane; a vertical support member extending generally perpendicular relative to the support surface, said at least two position sensors adjustably coupled to said vertical support member to provide vertical adjustment to said at least two position sensors to correspondingly vary a height of said sensing plane above said support surface; and a controller in communication with said at least two position sensors to determine a position of the user relative to said sensing plane, said controller including a closed loop feedback mode adapted to process at least one input parameter provided by the user, said closed loop feedback mode adapted to measure a performance criteria of the user related to said input parameter and to provide feedback to the user indicative of a measurement of said performance criteria.
