    摘要: A solder feeding device having a reservoir, a drive unit, a first lead, and a second lead is provided. The reservoir melts solid solder wire into molten solder, while the drive unit selectively feeds the solid solder wire into the reservoir. The first and second leads are in electrical communication with the drive unit. The first lead is positioned in the reservoir so that it electrically communicates with the second lead through the molten solder when the molten solder reaches a triggering level, but so that it does not electrically communicate with the second lead when the level is below the triggering level. The drive unit feeds the solid solder wire into the reservoir based upon a state of electrical communication between the first and second leads.

    摘要: A wafer-scale apparatus and method is described for the automation of forming, aligning and attaching two-dimensional arrays of microoptic elements on semiconductor and other image display devices, backplanes, optoelectronic boards, and integrated optical systems. In an ordered fabrication sequence, a mold plate comprised of optically designed cavities is formed by reactive ion etching or alternative processes, optionally coated with a release material layer and filled with optically specified materials by an automated fluid-injection and defect-inspection subsystem. Optical alignment fiducials guide the disclosed transfer and attachment processes to achieve specified tolerances between the microoptic elements and corresponding optoelectronic devices and circuits. The present invention applies to spectral filters, waveguides, fiber-optic mode-transformers, diffraction gratings, refractive lenses, diffractive lens/Fresnel zone plates, reflectors, and to combinations of elements and devices, including microelectromechanical systems (MEMS) and liquid crystal device (LCD) matrices for adaptive, tunable elements. Preparation of interfacial layer properties and attachment process embodiments are taught.

    摘要: Upon insertion of a fire alarm insert into a corresponding fire alarm mounting, the insert covers the mounting. The insert has a movable fastening comprising a ring, for example, for fastening the insert to the mounting. Indicator elements are included for indicating proper positioning of the insert relative to the mounting.
