An interconnection system that includes a daughter card and backplane electrical connectors mounted to printed circuit boards at connector footprints. The spring rate of beam-shaped contacts in the daughter card connector increases while mating with the backplane connector so that the retention force may be greater than the insertion force. Such a change in spring rate may be achieved by positioning the beam-shaped contacts adjacent a surface of a connector housing. That surface may include a projection that aligns with the beam-shaped contact. When the connectors are unmated, the beam-shaped contact may be spaced from the projection. As the connectors begin to mate, a central portion of the beam-shaped contact may be pressed against the projection, which has the effect of shortening the beam length and increasing its stiffness.

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 fiber optic connector insert for a connector may include a housing to be received within a passageway of a connector body, a circuit board extending longitudinally within the housing and having opposing first and second ends, and a first base and first electrically conductive pins carried thereby. The first electrically conductive pins may be coupled to the circuit board adjacent the first end thereof. The fiber optic connector insert may also include an opto-electronic (O / E) converter having a second base and second electrically conductive pins extending outwardly therefrom. The second electrically conductive pins may be coupled to the circuit board adjacent the second end thereof.

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 concerns a fastening member comprising a threaded part (150) and a head (100) with which the threaded part can be turned in order to tighten the fastening member in a corresponding element. The head (100) is formed of a plate (110) in one piece with the threaded part (150) and a cap (120) covering said plate. The cap (120) comprises a recessed portion (121) in which an offset is provided to form a housing (128). The plate (110) comprises a guide finger (111) located inside the housing (128) to form a stop against which the cap presses in order to impart a rotational movement to the plate in the tightening direction. The cap (120) further comprises a remotely interrogatable electronic component (130) comprising a data storage means (132). Said component is held in the recessed portion (121) with its end (133) protruding into the housing (128) so as to strike against the guide finger (111) and cause the fracture of the component when any attempt is made to unscrew or untighten the fastening member.

In a genome sequencing system and methodology, a protocol is provided to achieve precise alignment and accurate registration of an image of a planar array of nanoballs subject to optical analysis. Precise alignment correcting for fractional offsets is achieved by correcting for errors in subperiod x-y offset, scale and rotation by use of minimization techniques and Moiré averaging. In Moiré averaging, magnification is intentionally set so that the pixel period of the imaging element is a noninteger multiple of the site period. Accurate registration is achieved by providing for pre-defined pseudo-random sets of sites, herein deletion or reserved sites, where nanoballs are prevented from attachment to the substrate so that the sites of the array can be used in a pattern matching scheme as registration markers for absolute location identification. Information can be extracted with a high degree of confidence that it is correlated to a known location, while at the same time the amount of information that can be packed on a chip is maximized.

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.
