Abstract: The invention provides a waveguide connector assembly for the precision interconnection of mating arrays of parallel optical waveguides which are preferably photolithographically formed on substrates. The connector assembly has a base with several parallel channel walls cut along a surface of the base. A waveguide assembly is positioned on the base. The waveguide assembly comprises a substrate and several transparent, polymeric waveguides on and raised from a surface of the substrate. The waveguides have a polygonal cross section with flat edges. The waveguide assembly is positioned on the base such that each of the waveguides is set in one of the channels and contacts the walls of the channel at two or more points. A cover plate holds the waveguide assembly on the base.

Abstract: A multiple fiber positioner (MFP) provides a micromachined structure that includes multiple V-grooves in silicon created via anisotropic etching for positioning optical fibers in splices and connectors. The MFP has a permanently bonded cover to provide a one-piece, stand-alone component. This MFP component is used to create new fiber optic splices and connectors.

Abstract: An adapter for coupling a fiber optic connector has a terminus and a throat area provided with a fluted region. Mating connectors are aligned with the terminus by the fluted region. The adapter is injection molded as a single piece using polymeric materials and accommodates fiber optic connectors having tips in the form of right circular cylinders. The insertion force required between two connector tips during alignment is substantially reduced, minimizing damage to the fiber end-faces.

Abstract: The shield covers of an overmold shielded electrical connector have pivot detents stamped into their surfaces to provide a point for the shield halves to rotate on the center dielectric with a lever type action. When fully closed, the lever action assures that the cover tabs of the shield members securely contact the connector shell and maintain a positive ground.

Abstract: A magnetic tape cassette is provided with a combined biasing and shielding member composed of flexible ferromagnetic material having at least 50 percent glassy structure. The member decreases construction costs and increases shielding of the magnetic tape recorder head during operation.

Abstract: A magnetic theft detection system marker is adapted to generate magnetic fields at frequencies that (1) are harmonically related to an incident magnetic field applied within an interrogation zone and (2) have selected tones that provide the marker with signal identity. The marker is an elongated, ductile strip of amorphous ferromagnetic material that retains its signal identity after being flexed or bent.

Abstract: The effectiveness of thermal insulation of barriers, such as walls, floors, or ceilings of a residence, is assessed by measuring the effective values of insulation or R values, of thermal barriers. Suitable devices and procedures for utilizing such devices are provided. The R values so measured can be compared with those suggested for economic insulation in such sources as government publications to determine the desirability of augmenting existing insulation.The device comprises a holder and a temperature sensor and indicator means supported on a support slidably mounted in the holder. In one embodiment, a single device combines measurement of thermal insulation and comparison with suggested values for economic insulation. A direct measurement of whether installed insulation is adequate is thus provided.

Abstract: Efficient electromagnetic shielding envelopes made of wound metallic glass filaments are disclosed. They are made by winding the filaments around a suitably shaped mandrel and embedding the filaments in a matrix. These shielding envelopes have high shielding ratios at low magnetic fields and are easily manufactured.

Abstract: An adhesive bonding procedure for providing mechanical stabilization for metallic glass ribbons in fabric form. A curable liquid adhesive is applied to the metallic glass fabric and is cured to adhesively bond overlapping ribbons. The resulting composite shows a high quality appearance and texture of the surface, a high flexibility of the coating on the metallic glass fabric and an ability of the adhesive bond to prevent the fabric from fraying when subjected to flexing and torsioning.
