Abstract
Abstract An impingement member is moved in a predetermined path and direction at a velocity and with a force independent of each other with the user applying a resistance force to the impingement member at any point along or throughout its range of movement. In the disclosed embodiment, a bar is coupled to a pair of mechanical drive assemblies powered by DC motor through a disengageable clutch. Omnidirectional forces transmitted are monitored through sensors associated with the bar during movement thereof along a path by the drive assemblies. A sensor monitors the position, speed at position, direction, and reference information of the drive assemblies. The force and motion data from the sensors may be utilized to evaluate muscle response and provide biofeedback from different loading patterns and to control loading programs.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
167 words
In an exerciser, an impingement member, a source of motive energy, means for transmitting force between the energy source and the impingement member, means for monitoring the physical characteristics of movement of the impingement member and means for guiding movement of the impingement member, said force transmitting means including mechanical drive means operatively connected to the impingement member, said impingement member having opposite end portions, said mechanical drive means including a pair of reciprocating linkage assemblies respectively coupled to said opposite end portions of the impingement member, said guiding means including at least two fixed rods and slide blocks mounted thereon, means non-rotatively coupling the slide blocks to said opposite end portions of the impingement member for translation therewith along a path established by the fixed rods, and elastically stressed means interconnecting the coupling means and the slide blocks for transmitting translatory forces therebetween, said monitoring means including strain gauges mounted on said elastically stressed connecting means to produce analog signals proportional to the translatory forces transmitted.
Claim 2
Dependent Claim
167 words
In an exerciser, an impingement member, a source of motive energy, means for transmitting force between the energy source and the impingement member, means for monitoring the physical characteristics of movement of the impingement member and means for guiding movement of the impingement member, said force transmitting means including mechanical drive means operatively connected to the impingement member, said impingement member having opposite end portions, said mechanical drive means including a pair of reciprocating linkage assemblies respectively coupled to said opposite end portions of the impingement member, said guiding means including at least two fixed rods and slide blocks mounted thereon, means non-rotatively coupling the slide blocks to said opposite end portions of the impingement member for translation therewith along a path established by the fixed rods, and elastically stressed means interconnecting the coupling means and the slide blocks for transmitting translatory forces therebetween, said monitoring means including strain gauges mounted on said elastically stressed connecting means to produce analog signals proportional to the translatory forces transmitted.
Claim 3
Dependent Claim
51 words
The improvement as defined in claim 1 wherein the mechanical drive means further includes rotatable crank means operatively coupling the linkage assemblies to the energy source, said monitoring means further including position sensing means responsive to rotation of the crank means for producing digital signals as a function of such rotation.
Claim 4
Dependent Claim
31 words
The improvement as defined in claim 2 wherein the energy source comprises an electrical motor drivingly connected to the crank means through clutch means, said impingement member being a horizontal bar.
Claim 5
Dependent Claim
24 words
The improvement as defined in claim 1 including clutch means operatively connected between the energy source and the linkage assemblies for disabling the exerciser.
