A laser projector display module for a handheld device may include an electronics module, a miniaturized light source module electrically connected with the electronics module, a scanner module electrically connected with the electronics module, and an optical assembly configured to direct light from the light source onto the scanner module. The scanner module and the light source module may abut the electronics module.

Laser projector display modules and arrangements of components of laser projector display modules

A first and second capacitor plate are provided (and). Each capacitor plate has an opening disposed therethrough with the second capacitor plate being disposed substantially opposite the first capacitor plate. A first electrically conductive path interface is then disposed () in one of these openings as is at least a second electrically conductive path interface ().

Apparatus and methods relating to electrically conductive path interfaces disposed within capacitor plate openings

A microelectromechanical systems (MEMS) apparatus () having a footprint of about 1 to 10 millimeters by about 1 to 10 millimeters comprises a movable member () that can be stopped at either of at least two positions by electrically neutral stops (). Depending upon the needs of a given application, these stops may all be fabricated using materials deposition and removal techniques or some, though not all, may comprise an attached component.

Microelectromechanical system optical apparatus and method

A meso-electromechanical system () includes a substrate (), a standoff () disposed on a surface of the substrate, a first electrostatic pattern () disposed on the surface of the substrate, and a glass beam (). The glass beam () has a fixed region () attached to the standoff and has a second electrostatic pattern () on a cantilevered location of the glass beam. The second electrostatic pattern is substantially co-extensive with and parallel to the first electrostatic pattern. The second electrostatic pattern has a relaxed separation () from the first electrostatic pattern when the first and second electrostatic patterns are in a non-energized state. In some embodiments, a mirror is formed by the electrostatic materials that form the second electrostatic pattern. The glass beam may be patterned using sandblasting ().

Meso-microelectromechanical system having a glass beam and method for its fabrication

A MEMS based optical switch comprises a bottom electrode, a cantilever electrode, and a top electrode, all of which overlay a carrier board. An absence of a voltage differential between the top and bottom electrodes locates the cantilever electrode in a neutral position between the top and bottom electrodes. A presence of a voltage differential between the top and bottom electrodes locates the cantilever electrode in a position biased toward either the top electrode or the bottom electrode.

Optical switch providing a bi-directional rotation of an optical reflector

A plurality of mesoscale MEMS switches each share a common control voltage potential electrode (such as ground). So configured, a large number of switches can be provided without incurring a significant increase in required actuation voltage. Such switches can be inter-coupled in a variety of ways. In addition, in one embodiment, stacked switches can be provided. If desired, such stacked switches can share a common movable conductive switch element.

Mesoscale MEMS switch apparatus and method

A meso-scale MEMS device having a cantilevered beam is formed using standard printed wiring board and high density interconnect technologies and practices. The beam includes at least some polymer material to constitute its length, and in some embodiments also comprises a conductive material as a load-bearing component thereof. In varying embodiments, the beam is attached at a location proximal to an end thereof, or distal to an end thereof.
