Title: Innovations by Donghee Yeo

Introduction

Donghee Yeo is a prominent inventor based in Seoul, South Korea. He has made significant contributions to the field of sensor technology, holding 3 patents that showcase his innovative approach to dynamic vision sensors.

Latest Patents

One of his latest patents is a "Sensor for Accumulation Signal." This sensor includes a determining circuit and an output circuit. The determining circuit receives a first signal from a pixel in response to light and outputs a second signal associated with the occurrence of an event, based on the first signal. Based on the second signal being received in a time period between a first time when a third signal is received from a processor and a second time when a condition is satisfied, the output circuit outputs a fourth signal associated with the occurrence of the event in the time period to the processor after the second time.

Another notable patent is the "Dynamic Vision Sensor System." This disclosure relates to a dynamic vision sensor that comprises a pixel array, address event representations, and control logic. The pixel array includes a plurality of dynamic vision sensor (DVS) pixels connected to a plurality of row lines and a plurality of column lines. Each of the DVS pixels is configured to output an event signal in response to a change in light. The address event representations are configured to select one of the plurality of column lines and obtain an event signal output from DVS pixels connected to the selected column line. The control logic is configured to generate image data, including an object capable of generating a movement using an event signal output from each of the plurality of DVS pixels. The control logic divides the plurality of DVS pixels into a plurality of groups and allocates different readout times to each of the plurality of groups.
