Appl. No.:

11/891220

Inventors:

James Joseph Hogan - Lincroft NJ, US

International Classification:

H01F 17/00

US Classification:

336178

Abstract:

This invention disproves the conservation of energy in a core transformer as unavoidable. It shows that the design was a cause. Scientists, when they had a pair of equal forces (magnetomotive forces), allowed a pair of equal energies. This is changed by two innovations. One is called an “air-gap magnetic core”; it does not transfer all the force in the energy of a coil, to the core. And the other is a complete and radical change in circuitry.There is a common primary magnetizer. And then there are two primaries and two secondaries. This is done to use two different air-gap magnetic cores instead of one and only and same core. One core makes the new energy and the other subtracts from that new energy. This differs radically from the traditional secondary which allows the primary to take in an opposing and neutralizing current and then makes you pay for it.

Appl. No.:

8/135025

Inventors:

Steven B. Perry - Perrineville NJ
James P. Hogan - Sterling VA

Assignee:

Antec Corporation - Rolling Meadows IL

International Classification:

H04M 322

US Classification:

379339

Abstract:

A channel interface unit for interconnecting a two-wire transmission path which transmits analog signals and a digital signal transmission path. The channel interface unit includes a digital interface unit coupled with the digital signal transmission path and producing digital signals based on digital signals received from the digital signal transmission path, a converter for converting the digital signals to analog signals, a filter for removing noise, produced by the converter, from the analog signals, a driver, coupled with the two-wire transmission path, for amplifying the filtered analog signals, and a power supply for providing regulated voltage to the driver The channel interface unit also includes a device for decreasing effective capacitance by modifying the output impedance of the driver.

Assignee:

Keptel, Inc. - Tinton Falls NJ

International Classification:

H04B 346

US Classification:

379 6

Abstract:

A system is disclosed for verifying the integrity of each one of a number of communication paths, illustratively telephone subscriber loops, that runs between a near end location, illustratively a telephone company central office, and a corresponding remote ("far end") location(s). This system utilizes circuitry, such as a line verification module, that is located at the far end of each path to impart a selected test signal specifically a selected one of a number of sub-audible frequencies, thereto. In one embodiment, the circuitry continously transmits a test signal over the path. The level of the test signal is automatically adjusted such that this signal remains at an approximately constant amplitude regardless of whether that path is in an on-hook or off-hook condition. Central office monitoring circuitry is connected to the near end of every path being verified. For each such path, the monitoring circuitry first "learns" the frequency associated with the test signal appearing over that path, and thereafter detects a cessation or unexpected change in the test signal occurring at the near end thereof that is indicative of a possible loss of path (e. g.

Abstract:

A system is disclosed for verifying the integrity of each one of a number of communication paths, illustratively telephone subscriber loops, that runs between a near end location, illustratively a telephone central office, and corresponding remote ("far end") location(s). This system utilizes circuitry, such as a line verification module, that is located at the far end of the path to detect one or more conditions thereat (e. g. loop current and loop voltage) that are indicative of normal operation of the path, e. g. proper on-hook and off-hook conditions. As long as the path is normally operating at the far end, this circuitry would then transmit a test signal, e. g. a selected one of a number of sub-audible frequencies, over the path to the near end. This test signal is chosen to be substantially transparent to normal communication (e. g. local telephone company signalling and transmission frequencies) occurring over that path.
