摘要:
The present disclosure relates to light isolating arrays (can also be called "light pipes" or "light pipe arrays") that enable high transmission efficiency and isolation of light from one location, for example a lens, to another location, for example an array of photodetector diodes (each a "PD"). The light isolating arrays can provide optical isolation of the input light and can eliminate cross talk thus enhancing the resolution via increased contrast of the incoming signal. The light isolating arrays can also protect the PD's from contamination when used in outdoor devices.

The shaped composites of the present disclosure have metal powder bonded with glass powder. This feature provides the advantages of metal, metal powder, or glass composite materials, without suffering from the disadvantages. The composite is prepared with simple sintering methods, and can easily be formed into any number of desired shapes with dimensional characteristics and ingredients suited to a particular application.

The invention relates to an optical scattering element suitable for dispersing or scattering light transmitted by optical device by Mie scattering. The optical scattering element comprises a phase-separated or porous borosilicate glass having dispersed phase particles with a particle size of 200 to 500 nanometers or pores with a size of 200 to 500 nanometers, at a number density of 10 8 to 10 12 mm -3 . The optical scattering element can be prepared by subjecting a borosilicate glass to a controlled heat treatment to induce phase separation, and then optionally leaching out one of the phases with an acid leach. The optical scattering element can be, for example, attached to an end of an optical fiber or bundle of optical fibers. The invention also relates to a method of dispersing or scattering light by transmitting the light through the optical scattering element.

A transparent laminate structure is provided that includes a front section, a rear section, and a middle section securing the front and rear sections to one another with a gap therebetween. The front section has a strike face formed of an impact resistant layer and a polymer backing layer bonded to the impact resistant layer by an interlayer. The rear section has a forward face comprising at least one polymer layer. The front and middle sections can form an integral subassembly.

A conduit bundle includes an inner bundle of first-type conduits extending between inner-bundle first and second ends. The first-type conduits are mutually and adjacently bonded along coinciding portions of their lengths in order to define an inner-bundle rigid region that, as view into a plane orthogonal to the longitudinal axis of the inner-bundle rigid region, exhibits an inner-bundle periphery. A separation structure including a structure wall having structure-wall inside and outside surfaces is provided and the inside surface thereof is bonded to the periphery of the inner-bundle rigid region. The conduit bundle further includes a plurality of second-type conduits. Each second-type conduit includes a rigidly bonded region along at least a portion of the length thereof that is bonded to at least one of (i) the structure-wall outside surface and (ii) the bonded region of another second-type conduit of the plurality of second-type conduits.

The present invention provides a touch control assembly including a substrate for interfacing with a user and a touch keypad (102) removably connected to the substrate. The touch keypad includes a sensor (106).
摘要:
A flexible optic fiber cable is provided having a plurality of optic fibers grouped together as a fiber bundle with a flexible center section, in which the optic fibers are moveable relative to adjacent fibers in the fiber bundle, and two non-flexible end sections. Each of the two non-flexible end sections includes a generally uniform thickness protective layer extending over an outer surface thereof starting at a position spaced inwardly from a free end of the end section. A ferrule is located around and in an interference fit with the protective layer so that the end section is centered in the ferrule. An adhesive is located betwen the ferrule and the non-flexible end section from the position spaced inwardly from the free end of the end section to the free end thereof to connect the ferrule to the non-flexible end section.

The current disclosure relates to highly homogeneous glass sputter targets with a large aspect ratio and a high relative density. The glass sputter targets have properties that are desirable for forming thin films by physical vapor deposition processes such as sputtering. Methods for producing chalcogenide glass sputter targets are included.
摘要:
An ordered emitter array includes a plurality of micro-emitters configured to emit light. A light combiner configured as a partially fused optical fiber bundle has opposed bundle input and outputs ends between which there extends a plurality of constituent optical fibers. Each optical fiber has opposed light-input and light-output ends coinciding with, respectively, the bundle input and output ends. The light-input end of each optical fiber is aligned with a micro-emitter. Collectively, the light-input ends define a combiner input array having an input-array density indicative of the quantity of light-input ends per unit area, while the light-output ends define a combiner output array having an output-array density indicative of the quantity of light-output ends per unit area. While the diameter of each optical fiber remains constant, the optical fibers collectively taper such that the output-array density is higher than the input-array density.
