  • Patent number: 6271792
    Abstract: An antenna has a relatively thick primary dielectric between a ground plane and a conducting radiating element being fed by a conducting transmission line, first and second thin dielectrics on opposite sides of the primary dielectric, the relatively thick primary dielectric having a relatively lower dielectric constant than that of at least the second thin dielectric to increase the bandwidth transmission capability of the transmission line for a given impedance, the second thin dielectric couples substantially less power than is coupled with the primary dielectric and the second thin dielectric is of relatively higher dielectric constant promoting surface wave coupling and reduction of wave losses.

  • Patent number: 6150197
    Abstract: A process for fabricating heterolithic microwave integrated circuits. According to one exemplary embodiment, a glass substrate is fused to a silicon wafer, and the silicon wafer is etched to effect silicon pedestals. A glass layer is fused onto and about the silicon mesas and effectively polished to expose the tops of the silicon mesas. The backside glass layer is then polished to render a final thickness of the dielectric layer between the top surface and ground plane. In another exemplary embodiment, a layer of silicon may be selectively etched to form mesas that function as either pedestals or vias. A layer of glass may be fused to the silicon prior to etching. A layer of glass is fused to the silicon substrate and pedestals and planarized through standard polishing techniques. The wafer may be "flipped over" and polished in order to remove a substantial portion of the silicon or glass, depending on which is used. Thereafter, the integrated circuit is fabricated through standard techniques.

  • Patent number: 5876240
    Abstract: A stacked electrical connector 2 including right angle RJ-45 modular jacks 4 positioned in columns also includes LED's 38 positioned on the front mating face 18 of the connector 2. Internal passages 28 extend from the mating face 18 of the jack housing 18 and intersect channels 34 extending to the bottom pcb mounting face 22 where the connector 2 and jacks 4 are soldered to a printed circuit board. LED leads 42 are located in the passages 28 and contacts 44 are located in channels 34. Insulation displacement slots 48 at the top of the contacts 44 terminate the leads 42. The termination points are staggered and the leads 42 in a column are of different lengths so that contacts 44 of different lengths can engage corresponding leads 42. LED's 38 can thus be positioned beside mating openings 20 on the front of the connector 2 to provide status indications.

  • Patent number: 5876219
    Abstract: An electrical connector assembly for interconnecting a pair of circuit boards in parallel spaced-apart planes comprises first and second connectors. The first connector includes a dielectric first housing having a mating face and an array of first contacts exposed along the mating face. The first housing has a shroud which defines a boundary around the array of first contacts. The shroud has an edge at a height above the mating face and the first contacts are recessed below the edge. The second connector includes a dielectric second housing having a mating face and an array of second contacts exposed along the mating face for mating with the first contacts. The second housing is configured for complementary reception within the boundary of the shroud, wherein the shroud serves to align the first and second housings for mating before engagement of the first and second contacts can occur.

  • Patent number: 5720546
    Abstract: An electrical connector (3) for a fluorescent lighting fixture (1) comprises a circuit board (9) having an integral lamp ballast (10), a first bank of sockets (4) and wire connecting ports (11,12). A housing (16) encloses the ballast and the circuit board. The first bank of sockets are exposed from the housing for connection to fluorescent lamps, and the wire connecting ports are exposed from the housing for connection between external wiring from a source of electrical power and wiring extending to a second bank of sockets for the fluorescent lamps.

  • Patent number: 5655284
    Abstract: An apparatus and method for preparing the end of a cable which may be used in the fabrication of a Category 5 patch cord cable assembly. The apparatus includes a cable clamp subassembly and bonding members located between wire combs that position the cable wires side by side. The wires are bonded by heating elements located in the bonding members. These heating elements comprise wires mounted on a printed circuit board. The printed circuit board heater members can be replaced so that wires with different insulation and/or different sizes can be prepared by the tool. Exposed wire pairs are untwisted and laced in the wire combs. A cable clamp prevents the portion of the wires remaining in the cable jacket from untwisting. An insert is placed between two of the wires and the other six wires to improve near end crosstalk performance. The upper bonding subassembly is then rotated into place and the ends of the wires are bonded. The cable clamp is then shifted, moving the wires, and the wires are cut to length.

  • Patent number: 5523747
    Abstract: A cable management system which provides routing of wired services between service lines (16) and user lines (18). Each service line enters the cable system at a service termination unit circuit card (22) which also holds a portion of a crosspoint switch matrix (126). Each user line enters the system at a line termination unit circuit card (20). The service termination unit circuit cards are all mounted to connectors (36) on a first side of a centerplane board (24) and the line termination unit circuit cards are mounted to connectors (36) on the other side of the centerplane board. Pins (37) extending through the centerplane board interconnect the connectors so that any service line can be connected to any user line. A system controller card (26) mounted to the centerplane board communicates with the circuit cards via a bus (38) on the centerplane board.

  • Patent number: 5493772
    Abstract: A machine (10) for inserting metal hold down clips into a connector housing (26) is disclosed. An improved positioning mechanism (14) is provided for accurately positioning the housing (26) with respect to the parts to be inserted. The positioning mechanism (14) includes a track (64) for receiving and guiding the connector housing along a feed path and through an insertion workstation (60) where the hold down clips are inserted. The track (64) is vertically movable by a servo motor (100) while an adjacent feed mechanism (160) positions the connector housing along the track. The adjacent feed mechanism (160) is coupled to the track so that it moves vertically with movement of the track but moves horizontally by means of a second servo motor (190) independent of movement of the track. Both servo motors are mounted to the frame (12) structure and, therefore, do not contribute to the mass of the moving mechanisms.
