Filed:

Oct 29, 1999

Appl. No.:

09/430417

Inventors:

James L. Ruiz - Pleasanton CA 94588
Daniel L. Marks - Pleasanton CA 94588

International Classification:

G01M 328

US Classification:

73 37, 73 491, 73 495, 73 498

Abstract:

The present invention provides a single compact fitting for air, CO , or nitrogen pressure testing either gas piping or waste piping. Each fitting is used for gas pipes of a particular outside diameter and waste pipes of a single larger diameter. The typical plumber would have a set, for example four, of the inventive fittings available, one for each size waste pipe that is be tested. The inventive fitting couples easily to either gas fuel piping or waste piping. A single air-pressure gauge is used to test either type of piping system. The inventive fitting is not limited to waste, vent, or gas piping systems; it can also be used to couple to other piping systems. The inventive fitting, in addition to being more versatile than conventional air-pressure test fittings, is also smaller and more compact. The inventive fitting can be made from a one-piece core body or from several conventional component pieces.

US Classification:

362253, 362551, 362101, 239 18

Abstract:

A plumbing fixture or bathroom accessory includes a source of visible light, providing a pleasing aesthetic effect. Separate portions of faucet handles and/or spouts can be illuminated individually or as a group. A faucet spout and/or handle can include translucent or transparent material that captures and redirects light from the base, and may have opaque areas that provide other interesting patterns. The faucet light or lights can also serve as a nightlight for a bathroom or kitchen, saving the space that a separate nightlight would require. In another embodiment a light is provided in a faucet spout, which can illuminate a sink for a pleasing effect, and can also serve as a nightlight. The spout can be translucent, carrying light as well as water from its base. Lighted bathroom accessories can include towel bars or rings, toilet paper holders, paper towel holders, robe hooks, soap holders or grab bars.

Abstract:

Multi-sensor compressive imaging systems can include an imaging component (such an an RF, microwave, or mmW metamaterial surface antenna) and an auxialiary sensing component (such as an EO/IR sensor). In some approaches, the auxiliary sensing component includes a structured light sensor configured to identify the location or posture of an imaging target within a field of view of the imaging component. In some approaches, a reconstructed RF, microwave, or mmW image may be combined with a visual image of a region of interest to provide a multi-spectral representation of the region of interest.
