Abstract: An electrical connector assembly having a housing with terminal receiving passages. The terminal receiving passages have wire receiving portions. Wires are positioned in the wire receiving portions. The wires have cable jackets and center conductors. Electrically conductive components for controlling impedance of sections of the wires are positioned in the wire receiving portions of the terminal receiving passages. The electrically conductive components includes base walls with end walls, The end walls extend in a direction which is essentially perpendicular to planes of the base walls. The base walls have lengths which are approximately equal to lengths of the wire receiving portions of the terminal receiving passages. Insulation displacement slots are provided on the end walls. Lead-in sections extend from the insulation displacement slots in a direction away from the base wall.

Abstract: A connector system is disclosed. The connector system includes a single-pin plug that has at least two conductors electrically isolated from one another to provide two separate electrically conductive surfaces to facilitate simultaneously transmitting two different electrical signals through the pin at the same time. The connector system further includes a socket to receive the single-pin plug. The socket includes electrically isolated conductors to independently contact different conductive surfaces of the plug.

Abstract: A reconfigurable ADD/DROP multiplexer/demultiplexer apparatus is implemented by connecting a multiplexer/demultiplexer apparatus to a serializer/deserializer (SERDES) apparatus having a loop-back capability. By selectively activating the loop-back functionality of the SERDES apparatus the combination can be made to function as a reconfigurable ADD/DROP multiplexer/demultiplexer apparatus.

Abstract: An apparatus and method for enabling the transport of a higher line rate time-multiplexed data signals (e.g., Ethernet at 10 Gb/s) at a lower line rate (e.g., SONET OC-192) and for regenerating the higher line rate time-multiplexed data signals at the receiving end. At a transmitter end, a data stream compression apparatus removes a predetermined portion of non-unique, invariant content of the higher line rate data stream thereby generating the lower line rate data stream which is transmitted over a communication link to the receiver end. At the receiver end, a data stream expansion apparatus adds back the missing predetermined portion of non-unique, invariant content to the lower line rate data stream thereby regenerating the higher line rate data stream. A data compression multiplexer apparatus is formed by combining a plurality of the data stream compression apparatuses with a data multiplexer.

Abstract: A tube cleaner (42) for removing deposits from the inner wall of condenser and other types of tubes has scrapers (20) for contacting the inner wall of the tube. The scrapers (20) are adapted to contact the wall so as to form an angle of 90 degrees or less rearwards of the scrapers (20) when the cleaner travels through the tube, so as to achieve more effective cleaning. The scrapers (20) may consist of one or more split rings mounted in incomplete transverse channels (44) on a central core (32).
