Title: Innovations by Hong Chean Choo
Introduction
Hong Chean Choo is a notable inventor based in Johor Bahru, Malaysia. He has made significant contributions to the field of image sensors, particularly in advanced driver assistance systems. With a total of 3 patents to his name, Choo continues to push the boundaries of technology.
Latest Patents
One of his latest patents involves image sensors for advanced driver assistance systems that utilize regulator voltage verification circuitry to detect malfunctions. This electronic device features a pixel array with multiple rows of active imaging pixels and at least one row of test pixels. Each test pixel includes a test voltage generation circuit that produces a test voltage, a switching circuit that receives both the test voltage and an image pixel output signal, and a comparison circuit that asserts a counter reset signal when the output from the switching circuit matches the analog to digital conversion signal in voltage. A counter begins counting at the start of each test cycle and outputs its count upon stopping, which is proportional to the test voltage during the test mode.
Another patent by Choo also focuses on image sensors for advanced driver assistance systems, incorporating a test voltage generation circuit that generates a test voltage based on a regulator voltage. Similar to the previous patent, it includes a switching circuit, a comparison circuit, and a counter that operates in a test mode to ensure accurate voltage detection and malfunction identification.
