Abstract: A height referencing biochemical cassette comprising of a surface suitable to act as a coupling agent, a height referencing indicator, and molecules bonded to the surface. This cassette is a capable of use to test for bonding to these molecules through measuring the height difference between the indicator and the surface. This invention provides an efficient means to quickly and easily test for bonding of molecules to other molecules.

Abstract: One embodiment of a decontamination device for a surface, such as a probe, and method thereof in accordance with the present invention includes a first electrode, a second electrode, and a transformer. The first electrode comprises a housing with an opening and one end of the second electrode is positioned in the opening. The second electrode has an elongated-shape which tapers to a point at the one end adjacent to the opening. The transformer is mounted in the housing and has first and second pairs of leads. One of the second pair of leads is coupled to the first electrode and the other of the second pair of leads is coupled to the second electrode. A surface to be cleaned is placed adjacent to the point and the device is turned on for a preset period of time to generate free radicals, such as ozone plasma, which remove debris build-up on the surface.

Abstract: A water resistant and vapour phase corrosion inhibitor composite material for wrapping around metallic items for protection and to reduce corrosion during storage and transportation. The composite material comprises a high strength, tear resistant, flexible scrim, a low density layer impregnated with a solid form vapour phase corrosion inhibitor, and a barrier layer to reduce the transmission of water, water vapour, oxygen and other environmental gases through the composite material. The barrier layer also reduces the atmospheric loss of gaseous vapour phase corrosion inhibitor from around the wrapped item. Each layer is formed from a polyolefin material to create a multi-layered polyolefin composite material that is easily recyclable.

Abstract: An interface between a telecommunication network and multiple types of repositories. The invention is an apparatus and method for interfacing a CMIP network through a computer system to a repository. The computer system operates a log agent which translates CMIP instructions received by the computer system from the CMIP network to a set of standardized functions. The log agent is the same for all types of repositories. Each type of repository has a unique log access library. The log access library translates the standardized functions of the log agent to a form that can be interpreted by an application specific interface of the repository. Each type of repository has a unique application specific interface. Selection of a plurality of logged events can be determined by the log agent or the log access library.

Abstract: A refrigeration system which may be operated to control superheat at an inlet to a compressor (12) to produce a controlled superheat or to control a temperature of a fluid cooled by at least one evaporator (68) to provide the cooled fluid at a set temperature by controlling an opening of at least one expansion valve (62) in accordance with the invention includes a temperature control (206) which is activable to control the at least one expansion valve to cool the fluid to a set temperature in response to an enabling signal; a superheat control (208) which is activable to control the at least one expansion valve to control the superheat at the inlet of the compressor in response to an enabling signal; and a controller (204) responsive to the at least one logic operational state of the refrigeration system, for generating one of the enabling signals to activate one of the temperature control or the superheat control to control the at least one expansion valve to control superheat or provide cooled fluid at the

Abstract: A measuring system (40) for measuring a magnitude of a quantity in accordance with the invention includes a light source (52) for providing a light beam (58); a polarization controller (44), optically coupled to the light beam, for rotating a plane of polarization of the light beam through an angle in response to a control signal, which is proportional to the magnitude of the quantity being measured to provide a first rotated polarized beam of light; a sensor (46), coupled optically to the first rotated polarized beam of light and to the quantity being measured, which rotates the plane of polarization of the first rotated polarized beam through an angle proportional to the quantity being measured to provide a second rotated polarized beam of light; an analyzer (42), coupled optically to the second rotated polarized beam of light, having a constant plane of polarization for detecting the second rotated polarized beam of light produced by the quantity being measured; and a feedback and output circuit, coupled t

Abstract: A power generation system (40), (120), is disclosed in which the phase and frequency of alternating current generated by one or more generators (14) is locked to the phase of alternating current generated by a master generator (12) or to an external power source (124). A master control unit (42), (122) contains a master count generator (52) which generates a synchronization count which is transmitted to each generator control unit (44). The synchronization count at any point in time of the master count generator is directly proportional to the phase of electrical current being generated by the master generator or the external power source. Each generator control unit (44) receives the synchronization count and compares the synchronization count with a locally generated synchronization count which is proportional to the phase of electrical current being generated by a generator controlled by the generator control unit receiving the synchronization count.

Abstract: A snubber circuit for protecting power switches which modulate the flow of power through an inductive element in a power converter, such as a main primary winding of a transformer, includes a snubbing capacitor and a first switch which is operable to connect the snubbing capacitor to a power switch. A second switch is operable to connect the snubbing capacitor to an auxiliary primary winding of the transformer. The first and second switches are operated so that immediately prior to turn-off of the power switch, the capacitor is connected thereto to store the turn-off reactive power caused by turn-off of the power switch. The first switch is then opened and the second switch closed to couple the reactive power to the auxiliary primary winding to improve the efficiency of the converter.
