Abstract: A system, method, or device determines whether noise is present on a sampled and/or digitized sensed intrinsic cardiac signal based on a moving count of turning/inflection points of the signal. If noise is detected, the manner in which the cardiac signal is acquired, or the manner in which the device operates in response to the acquired cardiac signal (or both) is altered to reduce the risk of erroneously detecting noise as a heart depolarization and, therefore, inappropriately triggering or withholding therapy.

Abstract: The apparatus provides for the determination of the instantaneous phase in the respiratory cycle, subject's average respiration rate and the provision of ventilatory assistance. A microprocessor (16) receives an airflow signal from a pressure transducer (18) coupled to a port (17) at a mask (11).

Abstract: A electrocardiographic electrode assembly is attached on a spot of the body that is roughly inside an electrocardiowave-appearing region, and an optimum signal discriminating circuit of an electrocardiograph discriminates an electrode that is most suitable for an electrocardiographic measurement out of the plural electrodes of the electrocardiographic electrode assembly. The electrocardiograph receives electric signals (electrocardiowaves) captured by the discriminated electrode, and stores the electric signals in a memory. The electric signals stored in the memory, after a measurement of the electrocardiovaves finishes, is given as an electrocardiographic pattern to a doctor for diagnosis. In this manner, in the electrocardiographic measurement, the electrocardiographic electrode assembly is only needed to be attached on a spot of the body that is roughly inside the electrocardiovave-appearing region. Therefore, even an amateur or nonexpert can easily perform an electrocardiographic measurement.

Abstract: An apparatus and method for controlling power in digital logic circuitry is disposed in a body implantable biomedical device disclosed. A power switch, such as a power gating transistor, is coupled to a digital logic circuit element to selectively control the application of power to the circuit element. During each system clock cycle, power is supplied to the circuit element only for a duration of time required to effect switching of logic states. Power is removed from the circuit element during each system clock cycle when no switching of logic states occurs. A clock signal applied to the gate of a power gating transistor selectively controls the supply of power to the digital circuit logic element during each system clock cycle so as to appreciably reduce static power consumption of the circuit element.
