Introduction
Dong Woo Jee is a notable inventor based in Suwon-si, South Korea. He has made significant contributions to the field of photoplethysmography and light-to-digital conversion technologies. With a total of 2 patents, his work showcases innovative approaches to sensor design and signal processing.
Latest Patents
One of his latest patents is titled "Pixelated monolithic photoplethysmographic sensor having spiking neural network structure and driving method therefor." This invention discloses a pixelated monolithic photoplethysmographic (PPG) sensor that incorporates a spiking neural network structure. The sensor includes a plurality of input neurons that generate spike signals and are arranged in either a row or column direction. Additionally, it features output neurons that add the spike signals and generate an output spike signal when the result meets a predetermined reference value. A synchronizer is also included to convert the output spike signals into digital signals.
Another significant patent is the "Light-to-digital converter." This invention comprises multiple light-to-digital conversion units that create a first clock signal through delta-sigma conversion on a photodiode voltage from an unbiased photodiode. These units output a unit output signal by synchronizing the first clock signal with a reference clock signal. An adder is utilized to produce a digital output signal by summing the unit output signals from the conversion units.
