In the study, the \u2018negative delay\u2019 (temporal advance) of the analog signals achieved with SAT was investigated and the results analyzed with respect to the temporal advance achieved as well as the fidelity of the temporally-advanced output signals. The research project, completed in 2010, exceeded all of its objectives, having successfully demonstrated the ability of SAT to temporally advance a range \u2018known\u2019 constructed test signals (pulses and sine waves) and human electrocardiographic (ECG) signals (heart beats) from cardiac patients. The project resulted in a doctorate dissertation\u00a0(Hymel CM, Application of Signal Advance Technology to Electrophysiology, University of Texas Health Science Center \u2013 Houston, Graduate School of Biomedical Sciences, August 2010)<\/a>,\u00a0which was downloaded over 300 times in the first three years following its release.

Specifically, the output is advanced in time relative to the input, as the time delay through the circuit is negative. As such, the circuit output precedes the complete detection of the input signal. We refer to this as Signal Advance (SA) technology. Success in the development and implementation of this technology has important consequences for the development of novel interventional methodologies in cardiology and neurophysiology as well as significant potential in a broader range of both medical and non-medical areas of application.<\/p>\n Author: Dr. C.
