International Classification:

H04B 169

US Classification:

375130, 375135, 370242

Abstract:

A discrete multitone stacked-carrier spread spectrum communication method is based on frequency domain spreading including multiplication of a baseband signal by a set of superimposed, or stacked, complex sinusoid carrier waves. In a preferred embodiment, the spreading involves energizing the bins of a large Fast Fourier transform (FFT). This provides a considerable savings in computational complexity for moderate output FFT sizes. Point-to-multipoint and multipoint-to-multipoint (nodeless) network topologies are possible. A code-nulling method is included for interference cancellation and enhanced signal separation by exploiting the spectral diversity of the various sources. The basic method may be extended to include multielement antenna array nulling methods for interference cancellation and enhanced signal separation using spatial separation. Such methods permit directive and retrodirective transmission systems that adapt or can be adapted to the radio environment. Such systems are compatible with bandwidth-on-demand and higher-order modulation formats and use advanced adaptation algorithms.

Such methods permit directive and retrodirective transmission systems that adapt or can be adapted to the radio environment. Such systems are compatible with bandwidth-on-demand and higher-order modulation formats and use advanced adaptation algorithms. In a specific embodiment the spectral and spatial components of the adaptive weights are calculated in a unified operation based on the mathematical analogy between the spectral and spatial descriptions of the airlink.

International Classification:

C23C 1600

US Classification:

118715

Abstract:

This invention relates to the design of apparatus for processing electronic devices, including equipment for chemical vapor deposition. The new designs of gas separator plates, their configuration, and the regulation of gas flows through the system provides control over the pattern of precursor gas flow away from the separation plates, thereby decreasing the amount of byproducts that are deposited on the plates and throughout the reactor. New designs for shaping other surfaces of the dispersion head reduces contamination of those elements, and new designs for chamber panels decrease the deposition of byproducts on those surfaces, as well as other elements of the reactor. Decreasing deposition of byproducts increases the amount of thin film, and the quality of the film which can be deposited without requiring the system to be shut down. This increases the throughput of products in the deposition process, thereby increasing the efficiency of electronic device manufacture and lowering the cost.

Abstract:

This invention relates to the design of apparatus for processing electronic devices, including equipment for chemical vapor deposition or transport polymerization. The new designs of gas separator plates, their configuration, and the regulation of gas flows through the system provides control over the pattern of precursor gas flow away from the separation plates, thereby decreasing the amount of byproducts that are deposited on the plates and throughout the reactor. New designs for shaping other surfaces of the dispersion head reduces contamination of those elements, and new designs for chamber panels decrease the deposition of byproducts on those surfaces, as well as other elements of the reactor. Decreasing deposition of byproducts increases the amount and the quality of the film that can be deposited without requiring the system to be shut down for cleaning. This increases the throughput of products in the deposition process, thereby increasing the efficiency of electronic device manufacture and lowering the cost.

International Classification:

B32B 300

US Classification:

428 351

Abstract:

An article having a surface comprising an olefin polymer is marked with indicia using an ink comprising a binder capable of substantially complete cure at a temperature of about 100. degree. to 300. degree. C. for less than about 10 minutes and then heated to cure the binder. The indicia are permanent, e. g. are resistant to being rubbed off and are solvent resistant. Heat-recoverable marker sleeves having such permanent indicia are particularly useful for marking wires, e. g. in aircraft harnessing.
