Abstract: Aspects described herein provide a computer implemented radio frequency propagation simulation tool to allow the simulation of radio frequency propagation across a topographic area which has been very finely mapped in three dimensions to include possible obstructions to high frequency radio waves. A computer implemented RF propagation simulation tool may identify any possible obstructions one edge of which may lie in a simulated RF propagation path between two points, and apply an edge based RF diffraction model (a so-called “knife edge diffraction” model) thereto to simulate the RF propagation around the obstruction. In some aspects, a computer implemented RF propagation simulation tool may identify possible obstructions which in their entirety lie within the width of a simulated RF propagation path, and apply a further diffraction model (a so-called “shield diffraction” model) thereto to simulate the RF propagation around the obstruction.

Abstract: Embodiments of the disclosed is a system comprising a wearable command center. One such embodiment comprises a case clip top portion; a chest mount bottom portion; a hinge member assembly; a connector cartridge assembly; a case; and at least one structural guide rail.

Abstract: An improved jewelry ring sizing mandrel and method of use thereof for sizing of an improved anatomically correct jewelry ring, with the mandrel having a tapered elongated body, elongated pairs of opposing outward extending portions and being spaced apart from an adjacent outward extending portion with each pair of opposing outward extending portions defining an outer width, and pairs of opposing elongated recess cavities with one of each of the pair of opposing elongated recess cavities positioned between each adjacent opposing outward extending portions and defining a cavity depth that is less than either of the adjacent opposing outward extending portions with each pair of opposing recess cavities defining a cavity width and the recess cavity width of the pair of opposing recess cavities being less than the outer width defined by any pair of adjacent opposing outward extending portions.

Abstract: A method of manufacturing, tool for manufacturing and an improved ring design and configuration having an improved anatomically correct internal shank with an internal surface having a plurality of spaced apart inwardly projecting internal structures and recessed surfaces configured for enabling the ring to pass over the knuckle at a reduced ring diameter, and having an internal portion of the ring transformed from the standard and long traditional circular shape to one that compliments the shape of the knuckle over which the ring traverses, and having a narrower diameter when placed on the ring bearing back portion of an appendage of a wearer providing an improved fit and comfort of the ring during use by the wearer.

Abstract: The present invention is directed to an animal feeder sight glass device. The device is a single multi-layered component made of a foam gasket with a central opening which seats on a vessel having an outer wall with an opening in the wall, a transparent lens and an outer lens holder plate also with an opening aligned with the opening in the vessel. The multi-layered component is secured to the vessel with screws which pass through openings in the gasket and outer lens holder plate.
