Abstract:
The problem of modeling and designing a structure including a planar element(s) (e.g., antenna, RF circuit, etc.) arranged in association with a non-planar element(s) (e.g., non-planar packaging, a non-planar scattering element, a complex meta material, a periodic array element, etc.), in a computationally efficient and rigorous manner is solved by (1) modeling each of the planar elements using both conventional space-spectral analysis and complex space-spectral analysis to obtain an electro-magnetic (EM) signature matrix for each planar element, (2) determining (e.g., using a brute force modeling based on Maxwell's equations, by measuring experimentally, or by reading one from a stored library) an EM signature matrix (e.g., reflection and scattering matrices) compatible with those of the planar elements, for each of the non-planar elements, and (3) combining the EM signatures of the elements using matrix analysis to obtain a complete EM signature the structure.

International Classification:
H01B 734
US Classification:
174 36
Abstract:
A lightweight braided metallic shielding is applied to wiring harnesses to protect against lightning strikes and electromagnetic interference (EMI). The braided shielding has an open braid construction which may be as much as 40% lighter in weight and which provides better electromagnetic shielding than conventional braided shielding. The decrease in weight is achieved by utilizing a braid carrier application angle, as measured from the axis of the wire harness, which is as small as about eighteen degrees, so as to produce a braided shield that has as few as four picks per inch. The ensuing braided shield is very flexible and results in a degree of wire harness coverage which may be as low as about 60%, but which exhibits low electrical resistance which contributes significantly to lightning protection and EMI shielding.

International Classification:
B66B 1/34 B66B 5/02 B66B 5/12
Abstract:
A tension member for an elevator system includes one or more tension elements extending along a length of the tension member, and one or more a wave guide regions secured to at least one surface of the tension member or integral to the tension member and extending along the length of the tension member. The one or more wave guide regions are configured for transmission of a radio frequency (RF) data signal along the one or more wave guide regions.

International Classification:
H01H 47/00 H01P 3/16
Abstract:
A power electronics arrangement may comprise a power supply, a controller configured to receive a power from the power supply and generate an output signal, a waveguide, a receiver, filter, and converter (RFC) configured to receive the output signal via the waveguide, the RFC configured to generate a switching signal from the output signal, and a power switching device (PSD) configured to receive the switching signal from the RFC, wherein the controller transmits the output signal to the RFC through the waveguide via a transponder, the waveguide is coupled between the transponder and the RFC, and the PSD is galvanically isolated from the power supply.
