Abstract: A computerized system for certifying workers to work on a structure having RF antennae, having: (a) an access module to access the computerized system; (b) a non-site-specific training module that displays on-line information about RF antennae; (c) a site-specific training module that displays on-line information about the at least one RF antenna on the structure; (d) a certification module that conducts on-line testing of workers on the non-site-specific information and certifies workers for work at a job site by having the workers acknowledge that they have seen the site-specific information; and (d) a database module which stores: (i) non-site-specific information, (ii) site-specific information, and (iii) records of which workers have both have passed the on-line non-site-specific testing and seen the site-specific information.

Abstract: A screw structure with a stop ring includes a screw, a ferrule, and a stop ring. The stop ring is fitted on a threaded shank of the screw to push against a front end of the ferrule, so that the ferrule is pressed against a head of the screw. With the ferrule being firmly pressed against the head of the screw by the stop ring, the ferrule will not sway relative to the screw, allowing the screw structure to be stably sucked with a sucking tool and be highly accurately assembled to a printed circuit board.

Abstract: A mobile, modular communications device, featuring a multiple-slot base chassis designed to support a plurality of individual user-configurable and interchangeable personality modules, capable of providing the ability to accept secure/classified user communications, including voice, data and video, the means to encrypt or secure such user communications through either internal or external encryption capabilities, the means to optimize the secure voice, data and video communications for transmission across a remote reachback communications link and the ability to provide multiple network/uplink reachback transmission alternatives, such as local area networks, satellites, cellular, ISDN or other forms of fixed or wireless communications. The invention is intended to provide a standardized, structured and modular approach to the provisioning of different technologies within the overall system and to be capable of being deployed as a man-carry or rack-embedded unit.

Abstract: Methods of detecting atypical patterns of usage of electricity, determined by monitoring consumption at the primary line, permit detection of grow-ops and unusual line losses due to defective service lines. A meter having a high resolution is connected to the primary line and the data collected is compared to known consumption patterns thus identifying a potential theft or a loss. Once an atypical pattern has been found, the heat signatures of transformers fed by the primary line are measured. An unusual heat signature alerts the utility to load test the secondary lines of each residence fed from the transformer and thus locate suspect residences which may be grow-ops or to locate a line loss due to defective service lines.

Abstract: Method of drying a medium for producing a porous matrix from a solution, a paste, an extract, a granulated material or such, where a liquid inert agent is fed into a vessel (5) at controlled pressure and amount through a valve (7), transferring the pressurized liquid inert agent to a mixing vessel (4), said mixing vessel (4) also receiving the solution, such as paste, extract or granulated material, through an inlet valve (10), adjusting the pressure and temperature inside the mixing vessel (4) to desired levels by a release valve (6), upon complete mixing of the inert agent with the solution, the mixture is expanded into a porous matrix and injected into a drying circuit through a drying chamber (3), the matrix thereby being kept suspended in the drying chamber by the flowing drying medium, supplied by the blower (2), the matrix moisture being removed from the mixture through a heat exchanger coil comprising a first heat exchanger (11) where the water vapour is condensed and removed from the circuit and fina
