A cable tray expansion splice plate for connecting first and second cable tray sections end-to-end is disclosed. The splice plate includes an elongate body having a central section, an upper flange section, and a lower flange section. In one embodiment, the lower flange section defines a channel for receiving components of the first and second cable tray sections such that the lower flange section underlies the components. Fastener openings in the central section and the lower flange section receive fasteners to fasten the body to the cable tray sections. These openings include slots which permit the cable tray sections to move relative to one another in a longitudinal direction.

Methods, systems, and computer-readable media for disambiguating a search query are provided. A query may be ambiguous when the domain-confidence factors indicate a high likelihood that the search query may belong to two or more domains. A domain is a subject matter category such as shopping, sports, entertainment, music, or politics. A domain-confidence factor indicates the likelihood that a search query is related to a particular domain. Upon determining that a search query is ambiguous, embodiments of the present invention may present an interface that allows the user to place the search query into one or more domains. Updated search results, or other objects, may be returned based on the selection of a domain by the user.

A braking system including a brake, a brake actuator which is operable to apply a force to the brake to effect braking, an automatic braking controller, and a manually operable brake actuator control device, the brake actuator control device including a manually operable control part which is movable between a release position and an apply position and which is adapted such that movement of the control part by a user from the release position to the apply position causes the brake actuator to apply the brake and movement of the control part by a user from the apply position to the release position causes the brake actuator to release the brake, the brake actuator control device being characterized in that it further includes a control actuator which engages with the control part and which is adapted to effect movement of the control part from the release position to the apply position on receipt of an appropriate signal from the automatic braking controller.
摘要:
Described is a method for designing individual stages of a multiple cascaded etalon TDC device to allow continuous thermo-optic tuning over a desired range without inducing incremental signal distortion due to uncontrolled and unpredictable dispersion of the TDC during tuning. This allows the signal to transmit without encountering periods of incremental distortion or dark spots. The method includes prior knowledge of each etalon stage, after full assembly, for spectral group delay profile as a function of temperature through modeling and/or characterization. Characterization can account for performance variations that are due to allowed manufacturing tolerances.
摘要:
The present invention is directed generally to a method of identifying an insect pheromone. Initially, a candidate insect pheromone-binding protein is obtained and sequenced. Specific proteins may then be selected by observing the pattern of pheromone-binding protein expression in the insect stage, phase or caste; and/or in the antenna and other sensilla by, for example, in situ hybridization; and/or by comparison with sequence of known pheromone binding proteins. A composition of one or more pheromones may then be contacted with the pheromone-binding protein. Any pheromones bound to the protein may then be eluted and analyzed.
摘要:
A system for performing molecular biological diagnosis, analysis and multistep and multiplex reactions utilizes a selfaddressable, selfassembling microelectronic system for actively carrying out controlled reactions in microscopic formats. The device includes a power supply and waveform generator adapted to supply a DC bias and superimposed AC signal to the system through an interface to the array of microlocations.

A method is disclosed for treating gaseous effluent from a hydrocarbon pyrolysis unit to provide steam cracked tar of reduced asphaltene and toluene insolubles content. The method is suitable for preparing reduced viscosity tar useful as a fuel blending stock, or feedstock for producing carbon black, while reducing or eliminating the need for externally sourced lighter aromatics additives to meet viscosity specifications. The method comprises drawing steam cracked tar from a separation vessel, e.g., a primary fractionator or tar knock-out drum, cooling the tar, and returning it to the separation vessel to effect lower overall tar temperatures within the separation vessel, in order to reduce viscosity increasing condensation reactions. An apparatus for carrying out the method is also provided.
摘要:
An improved nanophosphor scintillator liquid comprises nanophosphor particles in a liquid matrix. The nanophosphor particles are optionally surface modified with an organic ligand. The surface modified nanophosphor particle is essentially surface charge neutral, thereby preventing agglomeration of the nanophosphor particles during dispersion in a liquid scintillator matrix. The improved nanophosphor scintillator liquid may be used in any conventional liquid scintillator application, including in a radiation detector.

A method of creating a simplified computer implement for engine model comprises obtaining a complete computer implement for engine model (110) and selecting, from the complete engine model (110), elements defining the simplified engine model (110). The method further comprises obtaining from a library of rules at least one computer implementable model creation rule corresponding to the selected elements and using that at one rule to create the simplified computer implementable engine model (110).
摘要:
A high availability computing system includes a plurality of computer nodes (for example, a server system) connected by a first and a second network, wherein the computer nodes communicate with each other to detect server failure and transfer applications to other computer nodes on detecting server failure. The system incorporates methods of maintaining high availability in a server cluster having a plurality of nodes. A group communications service, a membership service and a system resource manager are instantiated on each node and the group communications service, the membership service and the system resource manager on each node communicate with other nodes to detect node failures and to transfer applications to other nodes on detecting node failure.
