Latest Patents

One of Chen's latest patents is a method to verify telephone numbers. This method involves an authentication server that authenticates Voice over Internet Protocol (VoIP) devices. It includes receiving a request from an unverified VoIP device to verify its global telephone number over a computer network. The process entails searching for verified VoIP devices that have authenticated identities and caller ID service. The verified VoIP devices provide their telephone numbers to the unverified VoIP device, which then calls them to detect its own telephone number. If the detected numbers match the original number provided by the unverified VoIP device, it becomes verified.

Another significant patent is a graphic engine for approximating a quadratic Bezier curve in a resource-constrained device. This method approximates a quadratic Bezier curve represented by two anchor points and a control point. If the flatness of the line formed between the two anchor points is below a certain threshold, the Bezier curve is replaced with an edge between the two anchor points. If not, the curve is subdivided into halves, and the flatness is determined for one of the halves. This innovative approach utilizes multiplication and subtraction operations to approximate the triangular area formed by the anchor points and control point.
