    摘要： Described is a method for minimizing switching noise in the high and mid-frequency range on printed circuit cards or boards by means of a plurality of surface mounted decoupling capacitors (4). A novel configuration and implementation of capacitor pads (2) including the connecting vias (6) is also presented. As a result the parasitic inductance of the pads and vias can be significantly reduced. Thus the effectiveness of the decoupling capacitors in the mid and high frequency range can be increased, the voltage drop can be reduced and the system performance can be increased. Several design rules for the new pad via configuration lead to the significant reduction of the parasitic inductance. The proposal is especially important for high integrated system designs on boards and cards combined with increased cycle times.

    摘要： A fiber optic connector assembly (51) wherein two individual fiber optic connectors (13, 15) are retained in a side-by-side arrangement which enables relative freedom of movement therebetween so as to facilitate positioning of the retained two (also called a duplex) within a common housing (17). Such movement accommodates for manufacturing tolerances within the housing and/or connectors, while still assuring successful insertion within the common housing. An adapter (10), having two clamping portions (21, 23) (one for each connector) interconnected by a resilient portion (43), assures this movement.

    摘要： An assembly for interconnecting two relatively rigid circuit cards (16, 12) using a flexible circuit (18) for forming this connection is provided. The assembly includes a housing (20) which has a first pressure (28, 31) exerting member which has the flexible circuit reeved therearound. Second and third pressure (28, 31) exerting members are provided in spaced juxtaposed relationship against which the opposite legs of the flexible circuit are maintained to define therebetween a slot (38) for the reception of a circuit card (16). The assembly is inserted into a card substrate with the first pressure exerting means causing the flexible circuit to be biased into contact with the contacts on a substrate. A second circuit card is inserted into the slot between the legs of the flexible circuit, and the second and third pressure exerting members urge each of the legs as the flexible circuit into contact with the second circuit board.
