A thin keypad including a top surface layer, a light guide layer, a capacitive sensing layer and a piezo layer provides for touch input, pressure input and haptic feedback.

A capacitive position sensor has a two-layer electrode structure. Drive electrodes extending in a first direction on a first plane on one side of a substrate. Sense electrodes extend in a second direction on a second plane on the other side of the substrate so that the sense electrodes cross the drive electrodes at a plurality of intersections which collectively form a position sensing array. The sense electrodes are provided with branches extending in the first direction part of the way towards each adjacent sense electrode so that end portions of the branches of adjacent sense electrodes co-extend with each other in the first direction separated by a distance sufficiently small that capacitive coupling to the drive electrode adjacent to the co-extending portion is reduced. Providing sense electrode branches allow a sensor to be made which has a greater extent in the first direction for a given number of sense channels, since the co-extending portions provide an interpolating effect. The number of sense electrode branches per drive electrode can be increased which allows a sensor to be made which has ever greater extent in the first direction without having to increase the number of sense channels.

A steerable distal support system for accessing stenosis, partial occlusions, or complete occlusions within a body lumen. The steerable distal support system generally includes an elongate member that comprises a proximal portion, a more flexible intermediate portion and a deflectable distal tip. The deflectable distal tip is at a distal end of the elongate body to facilitate directionality and positioning of the steerable distal support system to the target site. Optionally, an expandable centering assembly may be disposed on the steerable support assembly to center and anchor the steerable support assembly within the body lumen.

Disclosed is an imaging directional backlight that cooperates with a spatial light modulator to direct light into a first viewing window for one set of image pixels and into a second viewing window for a second set of image pixels. The waveguide may comprise a stepped structure, where the steps further comprise extraction features hidden to guided light, propagating in a first forward direction. Returning light propagating in a second backward direction may be refracted, diffracted, or reflected by the features to provide discrete illumination beams exiting from the top surface of the waveguide. Viewing windows are formed through imaging individual light sources and hence defines the relative positions of system elements and ray paths. Such an apparatus may be used to achieve an autostereoscopic display with a flat structure, not requiring fast response speed spatial light modulators.

By introducing a stack of alternating high and low index dichroic material layers on the exit surface of a waveguide for a wedge type directional backlight, natural reflectivity differences between polarized components can be increased, effectively reflecting the vast proportion of S-polarized light rays, while at the same time transmitting the P-polarized light rays, of light impacting the exit surface of the waveguide at an angle sufficient to exit the waveguide. This recovers polarization in wedge type backlight systems, increasing illumination exiting the waveguide. Also, on the back reflecting surface of the waveguide, a birefringent material can be added to efficiently transform S-polarized reflected light from the dichroic stack, into returning P-polarized light. Because returning rays that are now P-polarized by the birefringent material have already achieved the critical angle for exiting the waveguide, the rays transformed to P-polarization can now also exit the waveguide, increasing waveguide illumination.

An interconnect module for an integrated circuit chip incorporates a thin, high dielectric constant embedded capacitor structure to provide reduced power distribution impedance, and thereby promote higher frequency operation. The interconnect module is capable of reliably attaching an integrated circuit chip to a printed wiring board via solder ball connections, while providing reduced power distribution impedance of less than or equal to approximately 0.60 ohms at operating frequencies in excess of 1.0 gigahertz.

A wound field synchronous machine includes direct oil cooling along a conductive sleeve with elongated semi-arcuate shaped channels which alternate with damper bar channels containing tie-rod supports structures. With a reduction in sleeve thickness permitted by the direct cooling, the overall weight of the machine is reduced.

Disclosed is a light guiding valve apparatus comprising an optical valve, a two dimensional light source array and a focusing optic for providing large area collimated illumination from localized light sources. A stepped waveguide may be a stepped structure, in which the steps may be extraction features optically hidden to guided light, propagating in a first forward direction. Returning light propagating in a second backward direction may be refracted, diffracted, or reflected by the features to provide discrete illumination beams exiting from the top surface of the waveguide. A two dimensional array of viewing windows may be produced. Such controlled illumination may provide for efficient, multi-user autostereoscopic displays with wide viewing freedom and low cross talk and near-eye displays that are substantially transparent.

The semiconductor layer may include a seed layer disposed proximal to the surface of the semiconductor layer and having the threading dislocations uniformly distributed therein.

A single-piece top surface display and integrated front cover for an electronic device. In one embodiment, the cover comprises a thin, flexible, transparent layer coupled with a supporting structure. The flexible layer is supported above a display screen which is coupled with pressure activated sensors located under the display screen.

When pressure is applied to the cover, the cover deflects and activates the sensors. In both embodiments, an accelerometer identifies valid input events.

The punch is generally fabricated from stainless steel and includes an outer tube, an intermediate tube, a central stylet, hub structures, and a distal articulating region.

The punch is able to create holes in the atrial septum of the heart or other structures and is easier to use than punches that are pre-curved near their distal tip since it is easier to advance through accessory catheters.

A recess portion is formed in a substrate to accommodate a light emitting element so as to be sealed with a sealant. A light guide layer formed of a thin transparent resin film is fixed onto the substrate via an adhesive layer to realize an illuminating device with a thin structure. The light emitted from the light emitting element is irradiated into the light guide layer via the sealant and the adhesive layer. The light fully reflecting on the boundary surfaces between the light guide layer and the adhesive layer, and between the light guide layer and the air layer passes inside the light guide layer. Then the light which has not fully reflected leaks outside from the surface of the transparent resin film which forms the light guide layer. This makes it possible to illuminate the surface of the illumination device 1A entirely with brightness.

A sealing technique is provided for forming complex and multiple seal configurations for fuel cells and other electrochemical cells. To provide a seal, for sealing chambers for oxidant, fuel and / or coolant, a groove network is provided extending through the various elements of the fuel cell assembly. A source of seal material is then connected to an external filling port and injected into the groove network, and the seal material is then cured to form the seal. There is thus formed a “seal in place”, that is robust and can accommodate variations in tolerances and dimensions, and that can be bonded, where possible, to individual elements of the fuel cell assembly. This avoids the difficulty, labor intensive cost and complexity of manually assembling many individual gaskets into complex groove shapes and the like. The seal material can be selected to be comparable with a wide variety of gases, liquid coolants and the like.
