Title: Innovations of Chih-Chen Chen
Introduction
Chih-Chen Chen is a notable inventor based in Hsin-Chu, Taiwan. He has made significant contributions to the field of projection technology, holding a total of 8 patents. His work focuses on interactive systems and projection apparatuses that enhance user experience and functionality.
Latest Patents
One of his latest patents is an interactive rear projection system. This system includes a projection screen, a projection optical engine, an input device, and a controller. The projection optical engine emits a projection beam that is projected onto the screen. The input device consists of a sensor and a first light source, both located on one side of the projection screen. The controller is connected to the projection optical engine, the sensor, and the first light source, managing the projection of a first beam towards the screen. When an object approaches the opposite side of the screen, the sensor detects a light spot generated by the first beam, allowing it to recognize the position of the object or where it touches the screen.
Another significant patent is a projection apparatus that includes a backlash detecting system and method. This apparatus features a gear structure and a positioning piece located on opposite sides of the lens barrel. The gear structure rotates around the optical axis, and as it does, the positioning piece rotates relative to it. A motor module drives the gear structure, while a positioning module measures the rotation of the positioning piece to generate a positioning signal. The controller uses this signal to calculate the backlash between the transmission gear and the gear structure.
