Abstract: A reversibly attachable muscle trainer includes a multi-arm structure with motion sensors and force generators for exercising opposing muscles of a person moving an implement so as to maintain an ideal movement. When attached to the implement, the muscle trainer trains the opposing muscles to consistently move the implement in an ideal way. While the person moves the implement with the muscle trainer attached, a processor receives signals from the motion sensors and determines differences between the actual implement motion and an ideal implement motion. The difference indicates a dominating force direction in which the dominating muscles urge the implement. The processor activates the force generators to apply external forces to the implement to urge the implement in various types of training force directions.

Abstract: The invention is directed to a muscle trainer and methods for exercising opposing muscles of a person moving an implement. If the opposing muscles were of appropriate strength, the opposing muscles would apply forces in opposite directions to the implement to assist in maintaining an ideal movement of the implement. The methods train the opposing muscles to consistently move the implement in an ideal way to accomplish the function. The methods include: (a) moving the muscle trainer through an actual motion; (b) determining a difference between the actual motion and an ideal motion, the difference indicating a dominating force direction in which the dominating muscles urge the muscle trainer; (c) applying an external force to the muscle trainer to urge the muscle trainer in the dominating force direction; and (d) using the non-dominating muscles to urge the muscle trainer against the external force to thereby exercise the non-dominating muscles.

Abstract: The invention is directed to a motion trainer for improving a person's movement of an implement by allowing the person to visualize the path of the implement during the movement. The motion trainer comprises an implement having a plurality of motion characteristic sensors located thereon for determining, among other things, the direction of the movement and the orientation of the implement during the movement. Biofeedback devices provide the person information regarding the positioning of the implement during the movement.

Abstract: A data acquisition apparatus acquires an analog input signal from an analog sensor, and generates digital data based on the analog input signal for processing by a personal computing apparatus. The analog input signal generated by the analog sensor has a voltage component which varies according to a condition sensed by the analog sensor. The data acquisition apparatus includes a first conversion circuit, such as a voltage-to-frequency converter, coupled to the analog sensor which receives the analog input signal and generates an analog information transfer signal having a signal component which varies in relation to the voltage component of the analog input signal. A signal transfer device, such as a portable audio record/playback device, records the analog information transfer signal and transfers it to a first audio input of the personal computing apparatus.

One end of the second arm member is pivotally coupled to one end of the first arm member. The system includes one or more joint angle variation sensors that provide one or more electrical characteristics that vary based on variation in the joint angle between the first and second arm members. The joint angle is variable over an angular range that includes a first angle and a second angle.
