Title: Sheet-metal antenna
Inventor: BARNETT RON
IPC: H01Q9/04
Filed: 2001-02-12
Abstract: A high-frequency, e.g., microwave, antenna is stamped from a single sheet of electromagnetically conductive material, e.g., a metal plate. A manufacture comprising a frame, a plurality of radiator antenna elements, a plurality of first supports each connecting a radiator antenna element to the frame, a feed network connected to the radiator antenna elements, and a plurality of second supports connecting the radiators and the feed network to each other and to the frame, are stamped out of the single sheet. A combiner may be included in the manufacture as well. The second supports provide alignment and rigidity during manufacture and assembly. Preferably, a plurality of the manufactures are stamped out side-by-side from a single roll for ease of automated manufacture and assembly. The frame is either made in two pieces or is bent relative to the resonator antenna elements along fold lines, to provide an offset of the radiators from a ground plane. The frame is mounted on the ground plane, and the second supports are then removed. Preferably, the feed network is positioned (e.g., by being bent) to lie closer to the ground plane than the radiator antenna elements.

Abstract: A method and system for a rendering engine architecture wherein graphics or other objects are detected and rendered for display to a user independent of  the source of the graphics to be rendered is presented. Stroke vectors are detected and rendered as raster graphics symbology for use in, for example, monochrome or color flat panel display devices. In one embodiment, analog stroke video analog to digital conversion is performed by over-sampling stro ke deflection and video signals relative to writing rate and display pixel resolution. Digitized stroke data is processed to create a display list of simple vectors. Rendering of graphics symbology with anti-aliasing is performed by graphics rendering of simple vectors with true anti-aliasing. F or hybrid stroke/raster formats, raster video analog to digital conversion is performed by oversampling relative to input resolution and display pixel resolution. Graphics symbology and raster video are merged through digital summation with symbology precedence. The overall effect is that maximum quality of symbology with background video is realized using the fullest capabilities of a high resolution color flat panel display. Analog stroke symbology inputs can be converted to high-quality, anti-aliased symbology wi th raster video on a color flat panel display.

Title: Patio umbrella with radiant heater
Inventor: CLARK WALTER B
IPC: A45B23/00
Filed: 1999-08-09
Abstract: A patio umbrella that includes a dining table and a fuel-burning radiant heater avoids overheating of the upper canopy (20) by mounting the support (24) on which the upper canopy rests in the shadow cast by a reflector (28) that converges upwardly to form a chimney portion (34). The reflector is affixed to the housing of the combustion chamber (18) by legs (32). In addition to reflecting radiant heat downwardly onto the table and the diners, the reflector shields the upper canopy support (24) from radiant heat and provides a duct (34) for venting the products of combustion. As the latter pass up through the chimney portion, cooler air is drawn up through the space (30) between the reflector (28) and the upper canopy support (24) thereby preventing hot air from stagnating there. The upper canopy support is mounted to the reflector and spaced above it by a number of insulative ceramic spacers (26).
