Abstract: A process for constructing a micro-electro-mechanical system (MEMS) device includes etching the topside of a silicon wafer to form a first support layer having asymmetric pads. The backside of the silicon wafer is etched to form a top layer with a mirror, beam structures extending from the mirror, and rotating comb teeth extending from the beam structures. Before or after the backside of the silicon wafer is etched, the topside of the silicon wafer is bonded to a glass wafer that forms a second support layer. Prior to bonding the silicon wafer to the glass wafer, the glass wafer may be etched to form a recess and/or a cavity that accommodates mobile elements in the silicon wafer. Due to the asymmetry of the pads in the first support layer below the rotating comb teeth in the top layer, oscillation can be initiated.

Abstract: A MEMS scanning mirror device includes a scanning mirror, rotational comb teeth, stationary comb teeth, distributed serpentine springs, and anchors. The scanning mirror and the rotational comb teeth are driven by electrostatic force from stationary in-plane and/or out-of-plane teeth. The mirror is attached to the rotational comb structure by multiple support attachments. Multiple serpentine springs serve as the flexible hinges that link the movable structure to the stationary support structure.

Abstract: A touch panel system includes a panel, first and second scanning mirrors located about first and second panel corners, a photodetector array along a first panel edge between the first and the second panel corners, and a stationary plane mirror along a second panel edge adjacent to the first panel edge. The first scanning mirror sweeps a light beam across the panel. The second mirror sweeps another light beam across the panel, a part of which reflects from the stationary plane mirror to back into the panel to sweep the panel from a different angle. The light beams, including the reflected part from the stationary plane mirror, strike objects on the panel and reflect towards the photodetector array. Angular positions of the first and the second scanning mirrors at the times the photodetector array detects the reflected light are correlated to object locations.
