Abstract: A communication connector assembly including a wire board, and a number of elongated terminal contact wires extending above a top surface of the board. The contact wires have free end portions for making electrical contact with a mating connector, and base portions formed opposite the free end portions for supporting the contact wires on the board and for connecting the wires to conductors on or within the board. The base portions project normal from the top surface of the board. Pairs of the contact wires are coupled to one another along a first coupling region between their free end portions and their base portions and horizontal with respect to the top surface of the wire board, so that crosstalk introduced by the mating connector of a given polarity, is reduced over the first coupling region.

Abstract: An enhanced communication connector assembly capable of meeting Category 6 performance levels with respect to near end crosstalk (NEXT), when the assembly is connected to a mating connector. The assembly includes a wire board, and a number of elongated terminal contact wires with base portions that are supported on the board. The contact wires have free end portions opposite the base portions for making electrical contact with a mating connector. A crosstalk compensating device on the wire board is constructed and arranged to cooperate with sections of selected terminal contact wires to provide capacitive compensation coupling between the selected terminal contact wires, when the contact wires are engaged by the mating connector.

Abstract: Capacitive crosstalk compensation coupling is achieved in a communication connector by the use of a capacitor compensation assembly. The assembly includes a housing constructed to be associated with a communication connector having elongated terminal contact wires. One or more crosstalk compensation capacitors are supported in the housing. Each compensation capacitor includes a first electrode having a first terminal, a second electrode having a second terminal, and a dielectric spacer is disposed between the first and the second electrodes. The terminals of the electrodes are exposed at positions outside of the housing so that selected terminal contact wires of the connector make electrical contact with corresponding terminals of the compensation capacitors to provide capacitive coupling between the selected contact wires when the contact wires are engaged by a mating connector.

Abstract: A memory addressing scheme suitable for use for either interleaving or de-interleaving data bytes of, e.g., a broadcast digital television (DTV) data stream. A number of memory branches are configured in a random access memory (RAM), wherein at least some of the branches have different numbers of memory locations for reading out and for storing data bytes, thus defining memory branches of different lengths in the RAM. A start address is determined for each of the memory branches in the RAM, corresponding to a first memory location of each branch. An offset value is determined for each memory branch, to be added to the start address for the branch for addressing a memory location of the branch. If an offset value does not exceed the length of a corresponding branch, an address corresponding to the sum of the branch start address and the offset value is generated for addressing a successive memory location of the branch, and the offset value for the branch is incremented by one.

Abstract: A communication connector arrangement has a contact wire support, and at least a first and a second pair of terminal contact wires with portions fixed on the support. Each pair of contact wires has contact portions for establishing electrical connections with a mating connector. A first leading portion of a first contact wire of the first pair, and a second leading portion of a second contact wire of the second pair, extend generally parallel to one another and are terminated at their ends by a capacitance element. Capacitive crosstalk compensation is thus produced at the contact portions of the terminal contact wires, when the latter are engaged by the mating connector. In a disclosed embodiment, the arrangement includes a jack frame joined with the contact wire support, and the terminal contact wires are positioned inside a connector opening in the jack frame to connect electrically with a plug connector when inserted in the connector opening in the frame.

Abstract: An electrical connector assembly has a terminal housing, and a number of electrically conductive connector assembly terminals supported by the housing. The connector assembly terminals have mid-sections that protrude from the housing for contacting terminals of a mating connector, and outside connection ends for making electrical connections with outside circuits. Free ends of the connector assembly terminals next to the terminal mid-sections and opposite the outside connection ends, are positioned inside the terminal housing. An electrical circuit component is mounted inside the terminal housing. The circuit component is connected to the free ends of the assembly terminals, so that the mating connector becomes electrically connected to the circuit component through paths between the mid-sections and the free ends of the assembly terminals, in proximity to the circuit component.

Abstract: A method of defining an address for a mobile terminal host (T/H) linked to a wired communications network, e.g, the global Internet. The method includes assigning an address to the mobile (T/H), the address corresponding in part to a first network base station to which the mobile T/H becomes linked, for example, by roaming into a cell of the base station. The address assigned to the mobile T/H is changed when the T/H roams and becomes linked to a second network base station, the changed address corresponding in part to the address of the second base station. At least one stationary terminal host in the network is informed of a current address assigned to the mobile T/H by establishing a connection between the mobile T/H and the stationary host. Message data is exchanged between the mobile and the stationary hosts as long as a connection is maintained between them.

Abstract: A communication connector assembly has a base support, and at least first and second pairs of terminal contact wires with base portions mounted on the base support. The free end portions of the contact wires define a zone of contact within which electrical connections are established with a mating connector, and each pair of contact wires defines a different signal path in the connector assembly. The first and the second pair of contact wires have corresponding leading portions extending from the free end portions, to a side of the zone of contact opposite from the base portions. A leading portion of a contact wire of the first pair, and a leading portion of a contact wire of the second pair, are constructed and arranged for capacitively coupling to one another thus conveying capacitive crosstalk compensation to the zone of contact where offending crosstalk is introduced by a mated connector.

Abstract: Reptiles are treated to eradicate or to prevent an infestation of ectoparasites, by applying a formulation having a substantially non-volatile active ingredient that is toxic to ectoparasites but generally benign to a reptile to be treated, on an inside surface of a container, and confining the reptile inside the container. In one embodiment, a substrate is placed in the container on which substrate the reptile rests when confined, and the formulation is applied on the substrate. The treatment is particularly suitable for snakes. Permethrin may form the active ingredient of the formulation. The treatment has residual benefits over an extended period of time.

Abstract: A low crosstalk connector configuration includes a terminal face, and at least three pairs of elongated parallel electrical connector terminals, wherein each pair is aligned in a plane normal to the terminal face. A first pair of terminals is aligned in a plane parallel to a second plane in which a second pair of terminals is aligned. A first distance between midpoints of the first and the second pairs of terminals in a direction parallel to the first and the second planes, equals a second distance between the midpoints in a direction perpendicular to the first and the second planes. A third pair of terminals is aligned in a third plane perpendicular to the first and the second planes. The third plane coincides with a point between either of the first or the second pair of terminals. A cable and connector assembly includes a length of cable with at least three pairs of twisted wires, with each wire pair connected to a corresponding pair of the connector terminals.

A crosstalk compensating device is associated with at least one of the terminal contact wires at a position where the wires are co-planar with one another.

Abstract: A tool for implementing a non-destructive separation of electrical components from one another. The tool has a handle part and a pair of legs extending from the handle part with a certain spacing between distal ends of the legs. The leg end spacing corresponds to a distance between a pair of holes in one electrical component, e.g., holes in mounting flanges of an electrical device whose terminals are soldered on a wire board, or holes in a wire board that is joined to another wire board via mating pin connectors soldered on the boards. The leg ends are constructed to engage the one component once the leg ends are inserted in corresponding holes in the one component, and the handle part is arranged to be manipulated to separate the first component from the second component when the leg ends engage the one component.

Abstract: A frequency modulated continuous wave (FMCW) phase shift radar system includes a transmitter, a receiver, and a linearly-tuned oscillator circuit arranged in the transmitter as a source of electromagnetic radiation. The linearly-tuned oscillator circuit has a voltage controlled oscillator (VCO); and a closed loop feedback circuit including a local oscillator and a harmonic mixer coupled to receive a stabilized local oscillator (LO) frequency signal from the local oscillator and a radio frequency (RF) signal from an output of the voltage controlled oscillator. The harmonic mixer mixes the LO frequency signal with the RF signal to produce an intermediate frequency (IF) signal, and a linear frequency discriminator is coupled to receive the IF signal and to produce an output voltage signal which is applied to an input of the VCO to stabilize the latter, thus completing the feedback circuit.
