Abstract: This disclosure relates to combination adjustable crutches and/or canes that can be converted from a crutch to a cane or vice versa. The present invention includes a main single support shaft made of lightweight-ridged square tubing. A unique handle that clamps onto said square support shaft. Additionally, a novel underarm support cradle with stem that telescopes inside said square support shaft to be adjusted up or down. Also, a novel way and means to provide auxiliary forearm support. Patient's hand wrist, forearm and upper arm then being in a natural ergonomic position, without twisting or bending of patient's hand, wrist and upper arm. Fatigue, discomfort, and pain then being minimized or eliminated. Also, a crutch/cane that can be firmly set aside, out of the way, in an upright position on a horizontal surface when not in use.

Abstract: A motion control drive system for producing and controlling programmed and remote controlled machine operations by directing and controlling the performance of a rotating output shaft. The output shaft is then used to provide drive power and programmed control of various machine operations required to be controlled by a program of predetermined machine operating commands. The final program of operating commands being stored on audio magnetic sound recording tape or other audio recording media for purposes of storage and subsequent use in directing and controlling a given machine. The program of operating commands being stored on two track audio magnetic tape in the form of dual, first and second, time varying and or fixed frequency audio signals whose frequencies interact and become the function of the commands to be executed.
