Abstract: An electrocardiac computer for determining and displaying the existence of certain abnormalities in ECG complexes. The ECG signal input is processed electronically to recognize and indicate the occurrence of excessively wide Q-R-S events within the ECG complexes and to total the number of such occurrences during a period of time, and to determine and subsequently display the level of elevation or depression, slope, shape and integral of the S-T segment portion of each ECG complex containing a normal QRS event.

Abstract: A respiratory gas analyzer is provided in the form of a breath gas measuring instrument and system in which the volume of air expired by a subject, the oxygen uptake in the expired air, and the oxygen consumption per unit of weight of the subject, are periodically calculated and digitally displayed. The instrument and system of the invention measures on a minute-by-minute basis the volume of expired air from the subject, and it provides a digital display of the total volume output of the expired air, compensated to a standard temperature and pressure. A true sample of the expired air is accumulated by gradual extraction within the system on a periodic basis for gas analysis, and a computer included in the system calculates the oxygen depletion of each total sample to standard temperature and pressure and provides a digital display of oxygen uptake. An additional computer is included in the system which responds to the compensated oxygen depletion and to the subject''s weight to provide a digital display of the oxygen uptake per unit weight of the subject.

Abstract: A light weight portable exercise machine is provided for maintaining cardiovascular tone and for rehabilitation of hospital patients confined to bed. Portability and versatility of the machine are enhanced by a mounting frame which is a part of the unit. Light but sustained exercise is accomplished through pedal operation by the feet and legs of the patient while holding the hands to bars on the frame. A number of permanent magnets are moved into exact juxtaposition opposite other magnets in progressive settings across a modified Faraday disc at a plurality of indented positions, and these magnets, with augmented inertia from a heavy rim, serve to achieve prescription exercise amounts for prescription exercise durations automatically terminated at set limits.

Abstract: An electronic measuring system is provided which measures the angular position of a rotatable mirror so as to provide an electrical output signal suitable for activating a digital display, or for introduction into a computer for further processing. The mirror, for example, may be incorporated into a galvanometer, gas analyzer, or other measuring instrument. In the practice of the invention, a moving light spot is directed to the mirror for reflection thereby to a photo-detector assembly. The reflected light spot reaches the photo-detector after a time interval which is dependent upon the angular position of the mirror, so that an electrical output signal representative of the angular position of the mirror may be obtained.

Abstract: An improved drive and control system for an exercise treadmill is provided which incorporates safety features for the prevention of a start-up at high belt speed after the treadmill has been turned off, or upon the resumption of power after a power failure, and to prevent rapid acceleration of the belt to a high speed condition in the case of certain control circuit failures. Circuitry, or other means, has been included in the drive system as an interlock whereby the manual on-off switch which activates the drive motor will not be effective until the motor speed control has been reset to the zero speed position. In addition, circuitry is included to provide for shutting down the drive motor in the event of a failure or malfunction in its control circuitry which could cause an unscheduled rapid increase in the treadmill belt speed to a high speed condition.

Abstract: An automatic blood pressure measuring and indicating instrument is controlled with fail-safe features such as fast dumping pressure from an inflated cuff upon actual detection of diastolic pressure, a predetermined period after pump starting. The pump is turned off either when a selected pressure has been reached, or a predetermined period after starting. If measurement has not begun at that time, fast dumping is initiated. Signal processing to eliminate artifacts includes the elimination of Korotkoff sound detect signals neither preceded nor succeeded by another. Synthetized Korotkoff sounds are used to accommodate very low heat beat conditions. Different size cuff adaption is provided for.

Abstract: The three-lead exercise cable is characterized by a connector portion having five pins mounted therein for attachment to a standard socket in an electrocardiogram machine. A housing is connected to the connector portion, and the pins in the connector portion extend into the housing. Inside the housing, three of the pins are wired together. One wire for the three-wire cable extends from the three wired pins for connection to the body of the patient. Similarly, two other wires extend from the two remaining pins for connection to the body of the patient to form a three-lead exercise cable, which is compatible with a standard electrocardiogram machine. To eliminate muscle noise or electromagnetic interferences, filtering devices may be mounted in the housing.
