Title: Mechanical design of laminar weak-link rotary mechanisms with ten-degree-level travel range and ten-nanoradian-level positioning resolution

Abstract

Enhanced mechanical designs are provided for weak-link rotary mechanisms for implementing angular rotations with a defined angular travel range and positioning resolution, for example, with ten-degree-level travel range and ten-nanoradian-level positioning resolution. A weak-link rotary structure has a predetermined pattern for implementing angular rotations with repeatable and reliable angular travel range and positioning resolution including a plurality of connecting links radially extending from a central portion with a predefined angular separation between the connecting links; each said connecting link having at least one pair of weak-link connections; alternate connecting links being coupled to a respective terminal, each said respective terminal being mounted to a connecting carriage; remaining other connecting links being coupled to a respective mounting portion of a mating part of the weak-link rotary structure.

Redundantly constrained laminar structure as weak-link mechanisms

Patent Shu, Deming; Toellner, Thomas S.; Alp, E. Ercan

Redundantly constrained laminar structures as weak-link mechanisms and a novel method for manufacturing the redundantly constrained laminar structures as weak-link mechanisms are provided. The method for producing the redundantly constrained laminar structures as weak-link mechanisms is carried out by lithographic techniques. A designed pattern is repeatedly chemically etched with a mask to produce a plurality of individual identical units. The units are stacked together to form the laminar structure and are secured together with fasteners. A high quality adhesive can be applied to the sides of the laminar structure to provide the mechanism equivalent to a single piece mechanism. Themore » « less

Six-degree-of-freedom multi-axes positioning apparatus

Patent Bieg, Lothar F. X. [Albuquerque, NM]

A six-degree-of-freedom multi-axes positioning apparatus is comprised of a geometry of six independent angle connectors. Each angle connector connects two fixed length rods to a pivot on one of two opposing platforms. The combination of an angle connector, at least two pivots and at least two rods having free ends connected to the pivots comprises a leg assembly. The spatial location of the upper platform is changed in relation to the lower platform by angular changes within each angle connector. This angular change results in degrees of motion within the apparatus defined as X, Y, Z, Tip, Tilt, and Rotation,more » « less

Weak-link capacitor

Patent Dirk, Shawn M [Albuquerque, NM]; Johnson, Ross S [Albuquerque, NM]; Wheeler, David R [Albuquerque, NM]; ...

A process for making a dielectric material where a precursor polymer selected from poly(phenylene vinylene) polyacetylene, poly(p-phenylene), poly(thienylene vinylene), poly(1,4-naphthylene vinylene), and poly(p-pyridine vinylene) is energized said by exposure by radiation or increase in temperature to a level sufficient to eliminate said leaving groups contained within the precursor polymer, thereby transforming the dielectric material into a conductive polymer. The leaving group in the precursor polymer can be a chloride, a bromide, an iodide, a fluoride, an ester, an xanthate, a nitrile, an amine, a nitro group, a carbonate, a dithiocarbamate, a sulfonium group, an oxonium group, an iodonium group, amore » « less
