Abstract: A multi-function health monitor is capable of performing a resting 12-lead ECG test, an ECG stress test, a 24-hour holter monitor evaluation and or a 30-day MCT monitoring. Using only 3 electrodes, the multifunction health monitor derives 6 channels (Limb leads & Augmented leads) of data with the noise cancellation (ground) effect of a virtual dynamic RL electrode. An electrode resistivity measurement system quantifies and may compensate for increasing resistance the electrodes and the patient that results from the length of time the electrodes are installed on a patient. The multi-function health monitor can provide data analysis through the gate array as the data is acquired. Data may also be stored for remote analysis as well as for transmission to remote stations upon occurrence of one or more threshold events. Parameters for threshold events may be adjusted remotely to obviate the need for a patient to travel for system adjustment.

Abstract: An image enhanced external counterpulsation system may be used to monitor a continuous real-time ultrasound image of the patient's heart during ECP therapy.

Abstract: A system for performing ECP and recording ECP system data, patient cardiac parameter data, and other data, and presenting the data in displays that are accessible to the operator in formats that assist in consistent treatment, interpretation of treatment data, and confirmation of therapeutic effect.

Abstract: An igniter for flaring natural gas at the surface of the ground in spaced relation to an oil and/or gas well bore drilling operation wherein excessive gas pressure is encountered during the drilling operation, and comprising a relatively long pipe extending from the well head to a position somewhat remote therefrom for directing excess natural gas away from the well head, a spark plug assembly disposed at the outer end of the pipe and including constantly arcing spark plugs for flaring of the escaping gas and the open end of the pipe, and an annular passageway in the proximity of the spark plugs for providing an adequate supply of oxygen for facilitating the burning of the gas.
