Title: Innovative Contributions of Andrew D MacLaurin
Introduction
Andrew D MacLaurin, an accomplished inventor based in North Epping, Australia, has made significant strides in the field of physiological event recognition. With a total of two patents to his name, his innovative work has a profound impact on medical technology, particularly in cardiac devices.
Latest Patents
Among his latest inventions, MacLaurin developed techniques that focus on physiological event recognition for use with a delta modulator. In this patent, the signal sensed on a heart pacer electrode is transformed by a delta modulator into a sequence of samples represented as 0 and 1 bit values. To determine cardiac events, the original bit sequence is delayed, and the difference between the original and delayed sequences is continuously subtracted in a clocked up/down counter. Once the counter reaches a predetermined threshold, three recognition circuits are engaged, each designed to identify a cardiac beat through specific criteria during a timing interval.
Another notable patent is centered around heart pacer time-domain processing of internal physiological signals. This invention describes a heart pacer where the sensed signals are processed in the time domain, allowing for a direct operation by a delta modulator on the sensed electrogram signal. This innovative approach eliminates any intervening filtering, resulting in a series of bits that represent variations in the sensed signal amplitude, thus enabling precise decisions regarding cardiac activity.
Career Highlights
MacLaurin's professional journey is closely linked to his role at Telectronics Pty. Limited, a company dedicated to creating advanced medical devices.
