Abstract: A MEMS device achieves a large angle of rotation of a plate about 2 independent axes by employing a handle portion of the plate which is isolated by respective springs coupling the handle portion to each of two actuators. A first actuator, which rotates the mirror about the same axis as done in U.S. Pat. No. 6,781,744 is essentially the same structure disclosed therein, but with the mirror plate thereof shrunken in size. This shrunken plate is coupled by a spring to the mirror plate of the instant invention. Movement of the shrunken plate causes corresponding movement of the handle portion, and hence the mirror. A second actuator, coupled by another spring to the mirror plate of the instant invention, rotates about a second axis that is perpendicular to the first axis and parallel to the substrate. The second actuator includes an actuator plate and an electrode thereunder.

Abstract: A heat-sensitive apparatus includes a substrate with a top surface, one or more bars being rotatably joined to the surface and having bimorph portions, and a plate rotatably joined to the surface and substantially rigidly joined to the one or more bars. Each bimorph portion bends in response to being heated. The one or more bars and the plate are configured to cause the plate to move farther away from the top surface in response to the one or more bimorph portions being heated.

Abstract: Targeted heating is employed to essentially only heat a material that is used as a spacer and to bond a first chip of a flip-chip to a second chip thereof and not the rest of the chips. In order to heat only the spacer-bonding material, one or more wires are located within, or adjacent to, the spacer-bonding material, and an electrical current is passed through the one or more wires causing them to heat. At the time of final bonding the heat generated by the one or more wires causes the spacer-bonding material to heat to its final curing temperature.

Abstract: An apparatus having a plurality of arrayed MEMS devices, each device having a parallel-plate actuator and a reflective plate, both of which are mechanically coupled to a flexible beam attached between two anchors. Advantageously, the use of parallel-plate actuators in the apparatus alleviates stringent requirements for the alignment of lithographic masks employed in the fabrication process. In one embodiment, each flexible beam has a relatively small thickness and a relatively large length to effect a relatively large displacement range for the corresponding reflective plate. Movable electrodes of different parallel-plate actuators are configured to act as an electrical shield for the flexible beams, which reduces inter-device crosstalk in the apparatus. Reflective plates of different MEMS devices form a segmented mirror, which is suitable for adaptive-optics and/or maskless lithography applications.

Abstract: A freely rotatable micromechanical plate is achieved by employing at least three rotatable plates that are each suspended from a substrate via respective springs, and are coupled via other respective springs to at least three moveable plate attachment points, so that rotation of the rotatable plates about an axis transfers motion to the moveable plate attachment points. Respective posts couple the movement of each respective moveable plate attachment point to a moveable plate. In operation, the rotatable plates may be individually rotated, and the resulting motion of each rotatable plate is passed to its respective moveable plate attachment point. The combined motion of the moveable plate attachment points is passed to the moveable plate via the posts. Using proper control, the plate may be made to tip, tilt and piston. Advantageously, the piston motion may achieve a high vertical movement frequency response.

Abstract: A polybutylene-based hot melt adhesive composition having a variety of end uses, particularly in construction and elastic attachment applications on nonwoven disposable articles. Unlike typical hot melt adhesives, the present composition can withstand exposure to emollients such as mineral oil and other oil-based ointments without experiencing catastrophic bond failure. The composition includes a polybutylene-based polymer or a mixture of a polybutylene-based polymer and a polyalphaolefin polymer, a tackifier resin, a plasticizer, a wax and a stabilizer. The hot melt adhesive composition can be applied using common application techniques such as extruding or spraying.
