Latest Patents

One of his latest inventions is the "Dual plane cross point switch architecture for a micro-PBX." This invention is a software reconfigurable cross point switch that selectively interconnects multiple phone lines and shared resources such as call progress monitors and DTMF receivers. The architecture enhances switching efficiency and flexibility by independently switching two separate planes, allowing different paths for the transmit and receive portions of a telephone connection. This invention is particularly useful for applications like conference summing.

Another significant patent is the "Minimum parallax stylus detection subsystem for a display device." This invention features a three-phase operation that improves the interaction between a stylus and a display. In the first phase, the stylus is at a distance, and no cursor is displayed. In the second phase, as the stylus approaches, a cursor image is generated, accurately reflecting its position. In the third phase, when the stylus is very close, the cursor is removed, and the actual path of the stylus is traced. This minimizes parallax error, allowing users to focus on the displayed image rather than the physical stylus location.
