11 Mar 1982TL;DR: In this article, a baseband system incorporates a mimic network to mimic the interference signal erroneously picked up by the receiving link from the transmitting link located at the same substation.
Abstract: A communication system for transmitting baseband digital signals (16) on an electrical power line (12). A pulse generator (14) produces digital signals which are limited to a frequency spectrum of 30 kHz to 300 kHz and applied directly, i.e., without modulation, to an electrical power line. At the receiving terminal (25) an amplifier (32) compensates for attenuation characteristics of the electrical power line and the received signal is then sampled (34) to extract the information from it. To avoid interference when both a transmitting and receiving link are located at a substation, the baseband system incorporates a mimic network to mimic the interference signal erroneously picked up by the receiving link from the transmitting link located at the same substation. The mimic signal is then subtracted from the interference signal to neutralize the effect of the latter. When both a baseband digital communication system and a carrier communication system utilize the same electrical power lines, provision is made for interrupting the baseband digital signal to allow communications via the carrier system.

29 Jul 1987TL;DR: In this article, a manufacturing data creation and distribution system comprises a computer with a graphics-capable display screen, which is capable of processing programmable instructions and creating data, and of generating graphic images on the display screen.
Abstract: A manufacturing data creation and distribution system comprises a computer with a graphics-capable display screen. The computer is capable of processing programmable instructions and creating data, and of generating graphic images on the display screen. A video camera is connected to the computer, and the computer includes hardware which can digitize the images transmitted by the video camera into a computer-readable form and display the digitized camera images on the display screen. A plurality of microprocessor-controlled workstations are networked to a microprocessor-controlled networking and file server, which can selectively retrieve data and transmit such data to the workstations for display. Also included within the computer is the capability to selectively manipulate the image-data received from the video camera to generate a manufacturing aid applicable to a product to be produced.

TL;DR: In this article, a variational 3D electromagnetic formulation for the general nonself-adjoint infinite periodic array problem is presented, which combines the vector finite element and Floquet boundary element techniques.
Abstract: We present a rigorous frequency domain variational 3-D electromagnetic formulation for the general nonself-adjoint infinite periodic array problem. The hybrid method described combines the vector finite element and Floquet boundary element techniques. It is general in the sense that it is applicable to infinite periodic arrays of the open or aperture-types. It is thus effective for modeling both the scattering and radiation performance of diverse FSS, absorber, and phased-array structures. The technique accurately handles arbitrarily complicated 3-D geometries, lossy inhomogeneous media and internal as well as external excitations. These analyses can be applied to general skewed grids under arbitrary scan and polarization conditions. >

11 Aug 1994TL;DR: In this paper, a gas sensor has a housing communicating with a monitored gas environment and carries the monitored gas through an integral catalytic hydrocarbon reforming chamber containing a reforming catalyst, and over a solid electrolyte electrochemical cell used for sensing purposes.
Abstract: A gas sensor measures O2 content of a reformable monitored gas containing hydrocarbons H2 O and/or CO2, preferably in association with an electrochemical power generation system. The gas sensor has a housing communicating with the monitored gas environment and carries the monitored gas through an integral catalytic hydrocarbon reforming chamber containing a reforming catalyst, and over a solid electrolyte electrochemical cell used for sensing purposes. The electrochemical cell includes a solid electrolyte between a sensor electrode that is exposed to the monitored gas, and a reference electrode that is isolated in the housing from the monitored gas and is exposed to a reference gas environment. A heating element is also provided in heat transfer communication with the gas sensor. A circuit that can include controls operable to adjust operations via valves or the like is connected between the sensor electrode and the reference electrode to process the electrical signal developed by the electrochemical cell. The electrical signal varies as a measure of the equilibrium oxygen partial pressure of the monitored gas. Signal noise is effectively reduced by maintaining a constant temperature in the area of the electrochemical cell and providing a monitored gas at chemical equilibria when contacting the electrochemical cell. The output gas from the electrochemical cell of the sensor is fed back into the conduits of the power generating system.
