Title: Innovations by David W Van Ess

Introduction

David W Van Ess is an accomplished inventor based in Arlington, WA (US). He holds a total of 4 patents that showcase his contributions to the field of medical technology. His work primarily focuses on advancements in electrocardiogram (ECG) technology and defibrillation methods.

Latest Patents

One of his notable inventions is the "Electrocardiogram filter." This invention presents techniques for identifying signals detected by electrodes on a patient's body during an ECG reading. A signal processor digitally filters the signal from the body, resulting in an electrocardiogram signal and a signal that identifies the presence and timing of signals from a pacemaker. Additionally, it can obtain other signals that reflect the quality of the electrical connection of the electrode to the body through digital filtering.

Another significant patent is the "Energy adjusting circuit for producing an ultra-low energy defibrillation waveform with fixed pulse width and fixed tilt." This energy adjusting circuit is designed for use with defibrillators. It reduces the defibrillation pulse energy that would otherwise be applied to the patient. The circuit can be integrated into the defibrillator or used as an adapter for conventional defibrillators. In pediatric applications, the adapter may include paddles specifically designed for babies and small children. The circuit can be constructed entirely from passive components and includes a divider circuit with two resistors to absorb a predetermined percentage of the defibrillation pulse energy.
