often do not perform as many exercises as needed and/or they do not achieve the proper force levels for satisfactory progress. We want to differentiate our products from others on the market by having them (a) beep when the desired force amount is reached and (b) count the number of cycles that the patient completes. Our equipment ranges from wrist and finger exercises up to squat types of exercises, so we probably need different sized devices to get the accuracy that we desire. One of the players on my softball team went to Cal Poly and says that small companies like yours can help us develop our product. He suggested using a ring-type transducer (whatever that is), but I don’t really care what you design as long as it
