Latest Patents
Hoyoung Chang holds a patent for a solution and methodology that detects minute surface damage or irregularities on the sensing surface of a capacitive sensor integrated circuit. The patent describes a process that involves acquiring a preliminary image of the capacitance readings for the sensor array. The sensing surface is then coated with an electrolyte solution, followed by the acquisition of an additional image while the surface is coated and/or after the electrolyte solution is removed. This innovative approach accelerates the manifestation of pixel degradation or failure caused by surface damage or irregularities. Defective regions are identified by changes in grayscale pixels in the preliminary image while the electrolyte coating is on the sensing surface and again after the coating is removed. Hoyoung Chang has 1 patent to his name.
