Abstract:
The manufacturers of electronic components have answered the requests of patients in recent years. Advancements were made with microprocessor-based controllers that allow for easy computerized adjustments, answering the need for increased control of the terminal device. Additionally, batteries have moved to Li-Ion, NiMH, and soon Li-Polymer, answering the request to provide a longer life to the charge, as well as the ability to top-off the charge. Another patient request was to increase the speed of the terminal device. In actuality, what patient wanted was a quicker response from the terminal device as they provided an input signal. An earlier response by the field was to increase the voltage to the terminal device. The higher voltage wasn’t the perfect answer because it was also difficult to operate at slow speeds. The Sensor Hand Speed answered these requests to have a more responsive hand that operates quickly, but also is able to operate very slowly according to the user’s input.
