Abstract: Tube connector having at least one polarizing element arranged such that a tube connection system can identify at least one parameter of light passed through said first polarizing element, wherein said at least one parameter comprises presence of light, light polarization state, light polarization direction, light intensity or combinations thereof.

Abstract: Disclosed is a thermoelectric generator arrangement using a standard burner wick guide, for example, a kerosene lamp, as a heat source and burner used with the thermoelectric generator arrangement. The burner includes an inner tube having a circular inlet opening, a rectangular opening, and continuous sidewalls extending therebetween.

Abstract: A cigarette urn and method of assembly of same that defines an interior passage for smoking debris to travel when multiple components of the urn are assembled into a self-standing, upright assembly condition. A top one of the multiple components has a sidewall opening. The multiple components may be disassembled from the self-standing, upright assembly condition into an overlapping assembly condition with the multiple components overlapping and taking up less overall volume that in the self-standing, upright assembly condition. A fire retardant or heat resistant material may be lining an interior contour of a base of the multiple components. The top one of the multiple components may be of substantially uniform diameter along a majority of its length.

Abstract: A mobile communication device (100) includes a receiver (102) which is normally shut off when the mobile communication device is idle. Upon the arrival of a paging time slot to which the mobile communication device is assigned, the mobile communication device turns on the receiver and begins receiving a composite signal including frequency diverse subchannels. The mobile communication device measures the delay spread of the subchannels (406). The receiver then adjusts the receiver on time for the next time slot based on the delay spread of the present time slot.

Abstract: A method for detecting nitrogenous materials within an object by means of Gamma-Resonance Absorption (GRA), including placing on one side of an object a target containing 13C for bombardment with a proton beam of approximately 1.75 MeV energy, to produce a source of 9.172 MeV gamma-rays for scanning the object, reading from the gamma-ray detector the total and the non-resonant attenuations of the incident photon flux, and deriving from the attenuations the net resonant attenuation and the spatial distribution thereof; wherein scanning the object includes: I. performing a rapid pre-scan to classify the overall gamma-ray-attenuation regime and locate regions of high physical density, in which longer scanning times might be required; II. performing a full scan to identify and locate regions that contain nitrogenous materials; and III. performing a plurality of scans in same or different segments to establish presence of explosives.

Abstract: A mobile computer security cart that includes a cabinet, a platform and an upright, The cabinet includes at least one shelf. The platform is coupled to the cabinet and has a top surface including an uncovered substantially planar surface. The upright is coupled to the platform and is configured to accommodate at least one display. The cart has an assembled configuration in which the platform rests on the top of the cabinet and the upright is coupled to the platform. The cart has a disassembled configuration wherein the upright is positioned adjacent to the front, rear or sides of the cabinet while the platform is positioned adjacent to the top or bottom of the cabinet.

Abstract: The container for disposal of cigarette waste includes a base, a hollow stem having an outer wall that contains an interior cavity of the hollow stem. The stem further includes a top and a bottom, where the stem is coupled to the base at the bottom. The container also includes a removable cap which is detachably coupled to the top of the stem. It further includes a disposal bucket attached to the cap. Once the cap is coupled to the top of the stem, the disposal bucket is suspended in the interior cavity of the stem. At least one hole is made through the outer wall of the stem near the top. Once the disposal bucket is placed in the interior cavity of the stem, the hole is located between disposal bucket and the cap.

Abstract: A shop desk with a desk body sized to define a volume bounded by a top, front, rear and side walls. A hutch is configured to fit within the volume when disassembled. The desk body is wider, longer and deeper than the hutch. The hutch secures to a top surface of the desk body when assembled. Legs support the desk body and a leg stabilizer platform connects to the legs at a location spaced from an underside of the desk body.
