Abstract: A connector for a communications system concentrates crosstalk in the front of a plug housing. The plug housing has front and rear ends. An internal chamber opens on the rear end and is defined by housing walls. A plurality of slots extend through one of the housing walls adjacent the front end and into the internal chamber. A plurality of contacts are mounted in the slots for movement between retracted positions spaced from the internal chamber and inserted positions extending into the internal chamber. An insert assembly has at least one insert member disposed adjacent at least one of the plurality of contacts. The insert assembly is made of a higher dielectric material than the plug housing.

Abstract: An apparatus/system for use in coupling power from a power supply to a device over a network transmission medium is provided. The coupling apparatus/system generally includes one or more common mode chokes that feature a first winding and a second winding, the first winding being electrically connected between the first terminal of the power supply and the first electrical conductor of the network transmission medium, and the second winding being coupled between the first terminal of the power supply and the first electrical conductor of the network transmission medium. The common mode choke generally includes at least one core for coupling the first and second windings of the one or more common mode chokes. An RJ45 to 110 IDC modular connector may be connected to a printed circuit board used to transfer high speed signals for telecommunication interface media connections. The printed circuit board is configured to help reduce near-end crosstalk (NEXT) without compromising impedance.

Abstract: A multi-stage surge protector/isolation barrier is provided for connection between a telephony device and a telephone network. The multi-stage surge protector/isolation barrier includes a first stage and a second stage. The first stage is operative to limit or clamp incoming voltage to a pre-defined level. In one form, the voltage limiting or clamping state includes a spark gap and over-voltage/over-current protector. The second stage is operative to limit or dissipate transients developed by the first stage. In one form, the transient limiting or dissipating stage includes transient filter circuitry. The transient filter circuitry may be implemented as LC filter circuitry. The subject multi-stage surge protector/isolation barrier helps prevent damage to the telephony device caused by voltage surges in the telephone network.

Abstract: The present disclosure is related to a modular plug housing insert device that makes electrical contact to a telecommunication plug to complete an interface media connection. The positional relationship of the conductors in the modular plug housing insert device are arranged to form a capacitance, such that the Near-end Crosstalk (NEXT) and Far End Crosstalk (FEXT) are reduced without compromising impedance.

Abstract: An acid dispensing system and method of dispensing swimming pool acid into a water circulation system of a swimming pool. The acid dispensing system includes a unique normally closed valve having an inlet connected to a supply of swimming pool acid and an outlet connected to a suction line of the water circulation system. The opening and closing of the valve is solenoid operated and regulated by two separate timers. The first timer delays opening the valve for a period of time (preferably about an hour) following activation of the pump in the water circulation system. The second timer allows the valve to remain open momentarily immediately following the first timer delay during which acid is drawn by suction only into the water circulation system (a time period of about a minute or less).
