Abstract: A servo control system for a machine tool or the like requires only a single computational resource, such as a microprocessor (12) to provide coordinated control along multiple axes. No active control mechanism is required for any axis outside of the single resource. A real time multitasking approach enables the single resource to control multiple axes of motion, with the control of each individual axis being carried out by means of simple, yet effective, routines that conserve computing power. The routines also facilitate the generation of geometric designs in other media, such as the display of such shapes on a video screen or via a printer.

Abstract: An implantable device (30) assists in the diagnosis of myocardial ischemia of a human heart and includes a plurality of electrodes (50-54) and a like plurality of sense amplifiers (72-76) for generating an electrogram for each of the electrodes (50-54). An analog to digital converter (80) reads the voltage magnitudes of the electrogram ST segments which are then stored in a memory (60). An implantable receiver/transmitter (63) is arranged to transmit the magnitudes of the electrogram ST segments to a nonimplanted external receiver.

Abstract: An implantable atrial defibrillator provides a pulse of defibrillating electrical energy to the atria of the heart in synchronism with sensed R waves in response to non-coincident sensing of an R wave at first and second areas of the heart. The defibrillating pulse is provided after a predetermined number of consecutive R waves are non-coincidently sensed to assure reliable synchronization. The atrial defibrillator is also operational in a marker mode wherein a number of synchronization marker pulses are delivered to the heart for detection on an externally generated electrocardiogram. The atrial fibrillation detector of the defibrillator is normally disabled and is activated when the sensed ventricular activity indicates a probability of atrial fibrillation to conserve a depletable power source. A plurality of lead systems are also described for use with the atrial defibrillator which reduce the quantity of electrical energy required to defibrillate the heart and ensure that the delivered atrial defibrillating electrical energy is substantially confined to the atria of the heart.

Abstract: An implantable device prevents tachyarrhythmias of a human heart which has arrhythmogenic tissue such as a myocardial infarction site. The device includes a plurality of electrodes configured for electrical contact with the heart and for placement in proximity to the arrhythmogenic tissue and a sensor including a single sensing electrode for sensing electrical activations of one chamber of the heart. A pulse generator coupled to the plurality of electrodes and responsive to the sensor provides the plurality of electrodes with an electrical pulse during each sensed electrical activation.
