Abstract: The muscle testing device, allows a person to determine, without assistance, the openness of their autonomic nervous system through determining the strength of a muscle, usually the arm muscle. The force of the muscle is applied against a gradually increasing known force, through the use of a solenoid. When the forces are equal a contact opens alerting a microprocessor to indicate this force on a display, through the use of a look-up table within the computer.

Abstract: The Tension Loss/Frequency Comparison Device is a simple and convenient way to determine, within a few hundred pulses, if two independent frequencies are identical in pulses per second. One frequency is essentially a controlled frequency; the other frequency is a randomly occurring frequency, such as the natural frequency of a taut string when it is excited, to be compared, in pulses per second, within a given time frame, to the controlled frequency. If the two frequencies are equal in time, a light is briefly turned on. The controlled frequency is continuously converted to a value representing the tension in a taut string, and displayed on an LCD; the frequency to be compared is the detected and amplified natural frequency of the taut string under test. If the light turns on, shortly after the taut string is excited, indicating an agreement in frequencies, the value shown on the LCD represents the tension in the taut string.
