Title: The Innovative Contributions of Hans Andersen
Introduction
Hans Andersen is a notable inventor based in Voellingby, Sweden. He has made significant contributions to the field of medical technology, particularly in the development of implantable defibrillators. With a total of 3 patents to his name, Andersen's work has the potential to save countless lives.
Latest Patents
Among his latest patents is an innovative implantable defibrillator with fibrillation-inducing capability. This device features a capacitor that can be connected to a voltage source for charging or to electrodes placed at the heart for delivering a defibrillation pulse. The method involves inducing ventricular fibrillation to calculate the minimum pulse energy required for successful defibrillation. The capacitor is charged to a prescribed voltage, significantly below the defibrillation threshold, and then briefly disconnected to deliver the pulse.
Another significant patent involves a method and apparatus for detecting a sequence of abnormal events in an electrical signal, such as the heart's depolarization signal. This invention compares a selective signal parameter to a defined threshold and measures the maximum value of the signal parameter for each event exceeding the threshold. The characteristic quantity corresponding to the statistical distribution of these maximum values is calculated and updated, allowing for the generation of a signal indicating the presence of abnormal events.
