Title: Allen Dettling: Innovator in Photoplethysmography
Introduction
Allen Dettling is a notable inventor based in Broomfield, Colorado, recognized for his contributions to the field of photoplethysmography. He holds 2 patents that showcase his innovative approach to medical instrumentation, particularly in pulse oximetry.
Latest Patents
Dettling's latest patents include a photoplethysmographic instrument that features switched gain, channel rotation, and bootstrap amplification. This pulse oximeter is designed to enhance signal processing characteristics by utilizing a time-division multiplexed gain circuit. The instrument incorporates a switched gain amplifier, which allows for the use of a fixed light source drive, thereby improving overall performance. Additionally, the device employs a transimpedance amplifier and bootstrap amplifier to optimize the signal from photodiodes. The time division multiplexing of optical input channels allows for customization of gain responses, effectively eliminating channel-specific error sources.
Another significant patent is a method for ambient light subtraction in a photoplethysmographic measurement system. This system utilizes a time division multiplexed signal to differentiate between ambient light levels and detected light levels at various wavelengths. By applying these signals to instrumentation amplifiers, the system produces a continuous output voltage that accurately reflects the difference between ambient and detected light, resulting in reduced noise and component requirements.
