A method forms an image with a reconfigurable array of mirrors. The method includes configuring the array by translating some of the mirrors such that distances of the mirrors of the array from a reference plane have a non-uniform spatial distribution. The method includes illuminating the configured array with a coherent light beam such that part of the light beam is reflected off the array and is projected on a planar viewing screen.

An apparatus includes a mechanical switch. The mechanical switch includes a bilayer with first and second stable curved states. A transformation of the bilayer from the first state to the second state closes the switch.

Mechanical switch with a curved bilayer background

Apparatus including a chip substrate having a first chip surface facing away from a second chip surface; an array of microelectronic elements on the first chip surface; and an array of conductors each in communication with one of the microelectronic elements, the conductors passing through the chip substrate and fully spanning a distance between the first and second chip surfaces. Process including: providing an apparatus including a chip substrate having a first chip surface facing away from a second chip surface, an array of microelectronic elements being on the first chip surface, an array of conductors each being in communication with one of the microelectronic elements and partially spanning an average distance between the first and second chip surfaces; bonding a temporary support carrier onto the array of microelectronic elements; removing a portion of the chip substrate, thereby reducing the average distance between the first and second chip surfaces; and forming an under bump metallization pad at the second chip surface in electrical communication with a conductor.

An electro-mechanical actuator includes a comb drive and a deformable connector. The comb drive has a first capacitor plate and a second capacitor plate. The capacitor plates have teeth capable of inter-digitating. The deformable connector is configured to apply a mechanical restoring force to the first capacitor plate. The deformable connector is configured to restore the first capacitor plate to be at an equilibrium rest position in response to no control voltage being applied across the capacitor. The comb drive is more engaged at the equilibrium rest position than at a mechanical stability threshold of the comb drive. The capacitor plates are disengaged at the equilibrium rest position.

Stable electro-mechanical actuators

An apparatus includes a substrate having a metallic surface, a structure, and a dielectric object facing the metallic top surface. The structure is configured to optically produce surface plasmon polaritons that propagate on the metallic surface. The dielectric object is controllable to adjust values of the dielectric constant at an array of different positions along and near to the metallic surface.

A representative embodiment of the invention provides an infrared (IR) imaging system adapted to (i) convert an IR image of an object into mechanical displacements of a plurality of movable plates, (ii) use the mechanical displacements to impart a corresponding spatial phase modulation pattern onto a beam of visible light, and (iii) apply spatial filtering to convert the spatial phase modulation pattern into a visible image of the object.

Apparatus including substrate, pusher assembly, and flexor assembly adjacent to pusher assembly. Pusher assembly includes hot and cold pusher arms. First ends of hot and cold pusher arms are anchored over substrate. Second ends of hot and cold pusher arms are coupled together and suspended for lateral displacement over substrate. Flexor assembly includes flexor arm, and conductor having actuator contact. First end of flexor arm is anchored over substrate. Pusher assembly is configured for causing lateral displacement of second end of flexor arm and of actuator contact over the substrate. Method includes providing apparatus and causing pusher assembly to laterally displace second end of flexor arm and actuator contact over substrate.

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.

Photo-sensitive MEMS structure

A representative embodiment of the invention provides an infrared (IR) detector having a movable plate supported at an offset distance from a substrate by a suspension arm. In response to a temperature difference between the plate and the substrate generated by the incident IR radiation, the suspension arm deforms and changes the offset distance for the plate. In one embodiment, the suspension arm has three rod-shaped bimorph transducers that lie within a plane that is parallel to the substrate. The transducers are also parallel to one another, with the transducer that is attached to an anchor of the suspension arm being located between the two transducers that are attached to the plate.

A laser projector having a configurable spatial light modulator (SLM) adapted to display various spatial modulation patterns and redirect illumination from a laser to form an image on the viewing screen. The laser projector drives the SLM to change spatial modulation patterns at a rate that causes the corresponding sequence of projected images to fuse to mitigate appearance of speckle in the resulting fused image. The SLM can be designed to redirect the illumination using either diffraction or specular reflection of light from the displayed spatial modulation pattern. In one embodiment, the SLM is a MEMS device having an array of individually addressable mirrors supported over a substrate and adapted to move (e.g., translate and/or rotate) with respect to the substrate.
