Motion Detection For Physiological Applications
US Patent:
6480111, Nov 12, 2002
Filed:
Jan 10, 2001
Appl. No.:
09/758840

Assignee:
Southwest Research Institute - San Antonio TX
International Classification:
G08B 2300
US Classification:
3405731, 3405722, 3405724, 3405726, 34082536, 34082546, 600534, 600535, 600595
Abstract:
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.
Electrode Systems And Methods For Reducing Motion Artifact
US Patent:
6912414, Jun 28, 2005
Filed:
Jan 28, 2003
Appl. No.:
10/352204
Inventors:
David A. Tong - San Antonio TX, US
Assignee:
Southwest Research Institute - San Antonio TX
International Classification:
A61B005/0408
US Classification:
600372, 600391, 600509, 600523
Abstract:
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.
