Abstract: Apparatus for selectively testing muscle strength and range of motion of a body part of a patient includes a housing having at least one contact area, and preferably two spaced apart contact areas, for contacting and aligning the apparatus with a body part to be tested for range of motion and an inclinometer to measure the angle of the apparatus and produce an angle signal indicative of the measured angle. The difference between the angle measured at one extreme of movement of the body part and at the other extreme of movement provides a measure of the range of motion. A force applicator coupler couples a force applicator to a force transducer to measure muscle strength. The force transducer produces a force signal indicative of the force applied by the force applicator to the force transducer.

Abstract: A process to determine the impact location of a transmitter-bearing object which is released for tracking purposes or to hit a target within a geographical area, wherein data obtained from the impact location can be used to determine the relation of the impact location and the target.

Abstract: Exercising apparatus is constructed with operating mechanism that includes a stationary platform elevated above user-accommodating level sufficiently to support a stack of weights in a position corresponding approximately with the position of the user's head, so weight selection is facilitated and so such mechanism can be attractively housed. A weight carrier includes weight connection members rising from an elevator platform that is adapted to be raised by muscle power of the user along with a user-selected number of weights connected thereto.
