Abstract: An electronic device for measuring relative angular positional displacement and angular range of motion for body segments and articulating joints of the human skeleton is disclosed. The device has a hand-held interface unit which is placed against the body segment or joint to be tested. Mounted within the housing of the interface unit is a shaft with a pendulum at one end and an optical encoder at the other. As the body segment rotates or the joint articulates, the pendulum swings in the direction of gravity, causing the shaft to rotate. The optical encoder generates an electrical signal representative of the amount of rotation of the shaft. The generated signal is fed to a microprocessor which processes the information and can produce on a display the change in angular position relative to initial angular position or the angular range of motion of the body segment or articulating joint.

Abstract: An adaptable method and apparatus for calibrating and conditioning sensor output to conform to a desired transfer function is provided. In one form, the invention allows use of a sensor system having nonlinear output characteristics when measuring a physical quantity and provides a response which varies linearly to changes in the physical quantity. In the calibration phase, a look-up table is built based on inputs from the sensor system and a reference transducer which behaves in the desired fashion to changes in the physical quantity. In the operation phase, the sensor system measures the unknown physical quantity and enters the look-up table to determine a corresponding reference value. Thus, the present invention adapts a sensor system to an application without restrictive considerations to individualized operating performance of the sensor system or environment of the application.

Abstract: A communication apparatus and method designed to interface with a standard, twelve key, dual tone, multiple frequency telephone, which allows easy, non-verbal entry of a message. Although particularly designed for use by the hearing and/or speech impaired with a dual tone telephone, the apparatus is equally adapted for use with practically any communication network where a keyboard with a limited number of keys is utilized and ambiguity resolution necessary. Generally speaking, the apparatus is connected to the earpiece of a receiving telephone and includes a tone pickup and decoder, a pre-programmed microcomputer and a message display panel. The message sender depresses a single key which corresponds to the alphabetic letter in the word being sent - because most keys on a telephone represent three letters, such a word is ambiguous when sent. The apparatus receives the ambiguous word and resolves the ambiguity in favor of a preprogrammed word which is displayed to the person receiving the message.
