100results about How to "Mechanically robust" patented technology

An interconnection system that includes a daughter card and backplane electrical connectors, each mounted to a printed circuit board at a connector footprint. The backplane connector has conductive elements with transition regions that allow the mating contact portions to be positioned on a uniform pitch while contact tail portions can be shaped to improve signal integrity or to provide a more compact and / or mechanically robust footprint. The conductive elements in both connectors are configured such that the contact tails of the ground conductors align from column to column, but the planar portions of the ground conductors in one column align with a pair of signal conductors in the other column, which improves mechanical and signal integrity. Mechanical integrity may be improved by forming the connector footprints with pads for the ground conductors that span multiple columns.

A microfluidic device includes, in one embodiment, a first silk film coupled to a second silk film with at least one microchannel therebetween.

A multipurpose seal with a lock, including a mobile closure apparatus of a casing containing a lock and an attachment element designed to be locked in the casing. The lock includes a barrel configured to move in the casing between a locked position and an unlocked position. A remote-interrogatable electronic component including a data-storage is maintained in a housing, which passes through part of the casing and part of the lock barrel when the lock barrel is in the locked position. Thus, any rotation of the barrel from the locked position causes the component to break.

The invention relates to a laminated rotor structure for a permanent magnet synchronous machine wherein disks (1) of a ferromagnetic material constitute the body of the rotor. The body includes bars (3) of a damper winding that extend axially close to the surface (2) from one end thereof to the other, and a circle of permanent magnets (4) disposed in a V-shaped configuration inside the circle formed by the bars, in which permanent magnets the first ends (5) are disposed close to the outer perimeter of the rotor and the second ends (6) are disposed closer to the central axis of the rotor. According to the invention, two permanent magnets (4) constitute a pair of permanent magnets wherein the magnets are disposed at an angle (a) to each other so that their first ends (5) are disposed at a distance from each other and their second ends (6) in proximity to each other. In addition, a pair of permanent magnets includes an air channel (7) that extends axially through the laminar structure of the rotor in direct heat transfer contact with the second ends (6) of the magnets in the pair of magnets.

A method for the fabrication of a three-dimensional thin-film semiconductor substrate with selective through-holes is provided. A porous semiconductor layer is conformally formed on a semiconductor template comprising a plurality of three-dimensional inverted pyramidal surface features defined by top surface areas aligned along a (100) crystallographic orientation plane of the semiconductor template and a plurality of inverted pyramidal cavities defined by sidewalls aligned along the (111) crystallographic orientation plane of the semiconductor template. An epitaxial semiconductor layer is conformally formed on the porous semiconductor layer. The epitaxial semiconductor layer is released from the semiconductor template. Through-holes are selectively formed in the epitaxial semiconductor layer with openings between the front and back lateral surface planes of the epitaxial semiconductor layer to form a partially transparent three-dimensional thin-film semiconductor substrate.
