Abstract: A rowing exercise device in which the return force for the rowing handle is provided by the force of gravity rather than an elastic cable. The rowing exercise device includes a stationary base and a moveable frame, which rotates or slides upwardly relative to the stationary base when a pulling force is applied to the handle, and then rotates or slides back down to the initial position under the force of gravity when the pulling force is removed.

Abstract: A handle for an exercise machine, e.g. a rowing machine, which is mounted on an end of a connecting linkage, e.g. chain, strap or cord, which extends along an axis of force application in the exercise machine. The handle includes first and second arm structures pivotally connected at their ends to a mounting bracket, which is attached to the connecting linkage. Handgrips are mounted on an the outer free ends of the first and second arm structures for pulling towards the users body, while separating the first and second arms apart, thereby replicating actual rowing strokes. Preferably, the handle is adjustable to various positions to replicate various rowing styles, e.g. conventional or crossover.

Abstract: The invention relates to a skating simulating exercise device including a force transmission means, which exponentially increases the amount of force required to spin a flywheel as the user approaches the limits of ovoid shaped boundaries, thereby eliminating abrupt stoppages and to simulate the digging in and pushing off actions in a real skating stride. The skating simulating exercise device also includes resistance to both rearward and lateral motion, which can be linked together to more effectively strengthen all aspects of a skater's motion.

Abstract: The present invention provides a method to automate the validation of dynamic data presented over telecommunications paths. The invention utilizes continuous speaker-independent speech recognition together with a process known generally as natural language recognition to reduce dynamic utterances to machine encoded text without requiring a prior training phase. Further, when configured by the end user to do so, the test system will convert common examples of dynamic speech, such as numbers, dates, times, and currency utterances into their usual textual representation.
