Receiver Filtering Out Both Systematic Pulse Noise And Random Noise

View page
US Patent:
39449327, Mar 16, 1976
Filed:
Dec 5, 1974
Appl. No.:
5/530128
Inventors:
Kouan Fong - Schenectady NY
Assignee:
General Electric Company - Schenectady NY
International Classification:
H04B 116
US Classification:
325427
Abstract:
A continuous wave (c. w. ) receiver is described comprising an amplitude limiting section, a commutating filter section, peak detecting means, and a threshold device. The receiver detects the presence or absence of an incoming signal over a very narrow, adjustable bandwidth. The limiting section clips the signal and noise at a predetermined amplitude and, in combination with the commutating filter, reduces the effect of noise, particularly impulse noise. The peak detector selects the highest output from the commutating filter and, in combination with the commutating filter, performs a pseudo-synchronization function when the received signal and an internal signal are not synchronized exactly.

Power Line Access Data System

US Patent:
39732401, Aug 3, 1976
Filed:
Dec 5, 1974
Appl. No.:
5/529998
Inventors:
Kouan Fong - Schenectady NY
Assignee:
General Electric Company - Schenectady NY
International Classification:
H04M 1104
H04Q 1100
US Classification:
340151
Abstract:
A two-way communication system is disclosed utilizing power transmission lines as the transmission medium. The system is a multilevel repeater system in which each repeater has a unique address. The lowest level repeaters poll the terminal stations connected thereto in time multiplex. Transmission over the system is in the form of tone codes, each level preferably utilizing a different set of tones from the next higher or lower level.

Signal Repeater For Power Line Access Data System

View page
US Patent:
39730875, Aug 3, 1976
Filed:
Dec 5, 1974
Appl. No.:
5/529999
Inventors:
Kouan Fong - Schenectady NY
Assignee:
General Electric Company - Schenectady NY
International Classification:
H04B 358
H04B 338
US Classification:
179170R
Abstract:
A signal repeater is described for relaying information in a two-way communication system superimposed on a power distribution network. The repeater senses signals passing in either direction in the system, translates the received signal to a different band or group frequencies, and transmits the frequency translated information. Provision is made for address-coding the repeaters so that, when connected in several levels, a particular path can be selected through the various levels. Provision is also made for a signal having priority in a system of such repeaters.

Station For Power Line Access Data System

US Patent:
39447235, Mar 16, 1976
Filed:
Dec 5, 1974
Appl. No.:
5/530129
Inventors:
Kouan Fong - Schenectady NY
Assignee:
General Electric Company - Schenectady NY
International Classification:
H04L 1500
US Classification:
178 3
Abstract:
A central station is described which acts as an interface between a two-way communication system superimposed on a power distribution network and a data processing computer. Information from the computer is converted into control signals for activating various sequences of sub-tasks by the communication system. Information from communication system is temporarily stored, converted into a suitable code, and transferred to the data processing computer by way of a teletypewriter terminal. Provision is also made for receiving and responding to priority signals from the system.
