摘要： A method and system for physiological monitoring using a microprocessor-enhanced magnetic field sensor to measure the mechanical effects of body motion is described. The measurements may be used for a variety of applications, such as detection of respiration, cardiac rhythms, and blood pressure. The source or detector may be made sufficiently small so as to be implantable. The system is sufficiently sensitive to provide output data for very small movements.

摘要： An electrode system for reducing noise from an electronic signal, the system including an electrode that provides the electronic signal, and a sensor that senses motion and provides a motion signal. The electrode system includes a controller that determines a noise value based on an analysis of the motion signal, and subtracts the noise value from the electronic signal. The electrode system can reduce or eliminate motion artifact from an electronic signal that can result in misdiagnosis, prolong procedural duration and inappropriate treatment of a patient.

摘要： Radio direction finding equipment has an array of direction finding antennas. The antennas are connected to receivers and signals from the antennas are processed, for example with a microcomputer, to give direction information derived from the phase difference between the signals. A reference antenna is also provided and this is of greater sensitivity than the other antennas. The direction information is derived from phase differences determined between the signal from the reference antenna and the signals from the other antennas.
