Abstract: An apparatus for allowing IEEE-1394-enabled devices to communicate with one another across an existing coaxial cable network in, for example, a house. Many houses have been “wired for cable” and have such a cable network in place. The network is, in its native state, unsuitable for IEEE-1394 communication. The apparatus allows processing signals from an IEEE-1394-enabled device for transmission across a coax. Signals received are converted and then provided to IEEE-1394 devices connected to the apparatus. One use for the apparatus is interconnecting audio/visual devices, for example high definition television receivers, DVD players, audio components and the like located in throughout a house to one another. DTCP encryption and decryption may be provided. The apparatus may be equipped with an optional SMI connector to allow communication over an optical fiber in lieu of the coaxial network. The apparatus is self-powered, deriving necessary power from the IEEE-1394 interface itself.

Abstract: An electromagnetic interference (EMI) shield for an optical connector. The EMI shield has a socket housing with a base and a canopy. The socket housing also has a front and a rear opening. The EMI shield contains an optical transceiver that is placed near the rear opening of the socket housing and contains two components used for signal conversion from optical and electrical signals. The EMI shield further contains a rear housing that is placed near the rear opening of the socket housing for maintaining the optical transceiver in a predetermined position. The EMI shield also contains a rear shield that is at the rear opening of the socket housing and a front shield that includes two, independent, optical sub-housing shields.

Abstract: An electrical terminal pin with a compliant portion adapted to be inserted into a plated-through hole of a circuit board. The compliant portion has a generally S-shaped cross-section with a width which gradually increases from a first axial end toward at least the middle of the axial length of the contact section. The pin has a mating portion joining the compliant portion for connection to another circuit element. Stiffening means are formed on one side of the compliant portion extending from the juncture with the mating portion to prevent breaking of the mating portion from the compliant portion when a transverse force is applied to the mating portion. The compliant pin is mass produced by using a strip of material having a generally uniform thickness throughout. The material is stamped in a given configuration and formed at successive stations to produce the S-shaped cross sectional compliant portion.

Abstract: The invention is a process of simultaneously making a plurality of jack-type electrical connectors characterized by the steps of molding together a plurality of housings (10); stamping and forming a plurality of groups (20) of electrical conductors (21) in the same spaced relationship as the housings (10); molding to each group of electrical conductors (21) a respective plastic member (50); placing the free ends of each group (20) of electrical conductors (21) through the passages (12) in respective housings (10) so that they extend into the housing cavities (13); forming the remaining portion of the electrical conductors (21) into the grooves (11) in respective housings (10); snapping the plastic members (50) into the recesses (18) in respective housings (10). The housings may then be separated for individual use.
