Abstract:
A computer input apparatus is disclosed which has improved safety control. Computer input devices with coherent light sources are popular. However, coherent light sources may cause serious and unrecoverable injuries to human eyes. Accordingly, there are several safety specifications defined by manufacturers and governments. Therefore, an improved device is disclosed that includes a calibration circuit and a fault detection circuit to control the operation current of a coherent light source to be within the safety specifications range, and to monitor for fault conditions. Furthermore, a computer input apparatus with coherent light source can be operated without the traditional optical lens.
