Two-dimensional position detection system with MEMS accelerometers, readout circuitry, and microprocessor for padless mouse applications.

Two-dimensional position detection system with MEMS accelerometers, readout circuitry, and microprocessor for padless mouse applications.

A hybrid two-dimensional position sensing system is designed with microelectromechanical systems (MEMS) for padless mouse applications. The X/Y-axis acceleration of the user's hand movements is measured by two MEMS accelerometer devices. These acceleration values are pulsewidth modulated and co...
