Abstract: Several complete fingerprint coils are attached to a support. The support is then rolled into a cylindrical shape such that a ray connecting the centers of each of pair of coils aligns with a component of a magnetic desired to be minimized or eliminated. In order to create this alignment, the support must have a length larger than the circumference of the cylinder which it forms, thereby causing a predetermined overlap. Since the coils are complete, there is no need to solder half-turns of coils to make a complete coil as was the case in previous coils. Since there are no solder points which are typically weaker than the remaining coil, the coil assembly is more resilient and less prone to breakage, making it more reliable.

Abstract: A receptacle connector (10) including a single plug-receiving cavity (20) adapted for mating with at least two different plug connectors (80,90). A pair of detection contacts separate from the signal contact array include contact sections (66) proximate tabs (34) of a conductive shield (14) and engageable therewith upon deflection of the tabs. Tabs (34) are so positioned as to be deflectable upon mating with one particular plug connector (90), and not deflected upon mating with another particular plug connector (80), generating a signal upon mating with the one connector (90) and not generating a signal upon mating with the other connector (80). Circuitry of a circuit board (24) becomes reconfigured upon receipt of the signal to correspond with transmissions from the one connector (90).

Abstract: A shield for an electrical connector for being mounted in a panel cutout (62), wherein spring fingers (46,102,202,302) of the shield are engaged with surfaces defining the panel cutout (62) and are deflected thereby toward sides of the connector. Free ends (48,104,204,304) of the spring fingers are so formed that upon spring arm deflection the free ends enter into electrical engagement with other portions (54,108,210,310) of the shield to enhance the shielding effectiveness.

Abstract: This invention provides a modular jack receptacle connector (2) which has at least one recess (10) for receiving an indicator (4). The recess is profiled to have a lead receiving section (26) with detents (32) along its sides for retaining at least one of the leads (6) which extend rearwardly and then downwardly from the indicator (4). Also provided along the sides of the recess are guide projections (12) for cooperating with guide recesses (14) in the indicator (4) for proper alignment of the indicator in the receptacle (2).

Abstract: A magnetic resonance system includes a cylindrical shield disposed between a quadrature RF coil and surrounding gradient coils. The shield includes a pair of copper sheets separated by an insulating dielectric sheet. A pattern formed by cuts in one copper sheet aligns with the currents induced in the shield by one of the RF quadrature fields, and a pattern formed by cuts in the other copper shield aligns with the other RF quadrature field. The copper sheets are shorted together to prevent voltage breakdowns and short cuts are made in each to prevent gradient induced eddy currents.
