Abstract: A system to measure forces on a device inserted through the skin into a human or animal body to introduce or remove material.

Abstract: An apparatus for the functional assessment of human activity. The invention comprises four major components: the data acquisition unit, a body suit interface unit, a body suit having a plurality of mercury switches and a graphics oriented software package. The body suit is made from a non-conductive material, preferably a thermalactyl material with sensors permanently attached in position corresponding to the movements to be measured. The sensors have no direct electrical contact with the human wearer thus permitting the measurement period to extend to many hours. A portable data acquisition unit which is connected to the sensors enables the system to be used "on the job" to obtain mobility measurements under actual conditions. A graphic analysis means, connected to said data acquisition means, is provided for providing a visual display of the length of time that the human has spent in each of the pre-determined positions and the range of motion measured by the data acquisition unit.

Abstract: A method of (and apparatus for) diagnosing a patient to measure sensory disturbances of the patient that includes the steps of applying normalized vibrator forces to a body portion or part (e.g., the finger) of the patient; automatically effecting discrete, but variable, vibrations of the body portion over a wide range of frequencies and at various vibratory amplitude levels at each vibration frequency; and noting the onset of sensory perception by the patient on an up-cycle at each vibration frequency and correlating the information, so derived, with the physical condition of the body portion or part. The method contemplates, once the onset of vibratory perception is achieved, in an up-cycle, decreasing the amplitude of vibration at each vibration frequency until the patient ceases or fails to sense the vibration and, in part, correlating the lower level of sensory perception to the condition of the body portion or part.

Abstract: A system for noninvasively sensing ocular pulses of a mammal, which pulses serve as a basis for indicating presence of a disease or malfunctioning body part such as, for example, a condition of arterial occlusion. The system employs piezoelectric transducers to sense the ocular pulses which are analyzed, also, in the case of arterial occlusion with simultaneously obtained ECG signals.
