This invention involves a system and method for the installation of a prefabricated composite structural members. The system utilizes deck panels which have a plurality of steel C-beam pairs attached to the underside such that a series of channels is formed. Bored through each deck panel is a plurality of access holes which projects through the panel and into one of said channels. Thus, installers can access underlying bridge girders from the surface of the deck panels thereby allowing for top-side installation. The system also provides a top-side vertically adjusting device for raising or lowering the deck panels to allow for the top-side installation of shimming devices.

A thruster system has a main bipropellant propulsion unit including a propulsion engine (50) and bipropellant supply having a tank (3) for an oxidizing agent and a tank (4) for a fuel. An auxiliary cold propellant thruster (21) uses propellant supplied by bleeding off vapor from the contents of the oxidizing agent tank (3).

The present invention provides a fish cage having a body portion and floats or weights attached thereto at one of a plurality of different positions so that the cage will float in water with a first part exposed and a second part submerged. Changing the position of attachment of the floats or weights results in different first and second parts being respectively exposed and submerged allowing successive cleaning of different first parts of the cage body.

Disperse monoazo dyestuffs, free from carboxylic and sulphonic acid groups, derived from 3,5-dinitro-2-amino thiophene as disazo component and an arylamine coupling component exhibit superior properties when used to give colorations to textile materials such as secondary cellulose acetate and cellulose triacetate, polyamide and aromatic polyester textile materials, said colorations having excellent fastness to light and to wet and dry heat treatments. The dyestuffs also have high tinctorial strength and excellent dyeing and build-up properties and produce depths of shade which are relatively independent of the dyebath pH, or the temperature of the dyebath or the liquor ratio of the dyebath.

The invention is system and method to recognize speech vocalizations using context-specific grammars and vocabularies. The system and method allow increased accuracy of recognized utterances by eliminating all language encodings irrelevant to the current context and allowing identification of appropriate context transitions. The system and method creates a context dependent speech recognition system with multiple supported contexts, each with specific grammar and vocabulary, and each identifying the potential context transition allowed. The system and method also include programmatic integration between the context dependent speech recognition system and other systems to make use of the recognized speech.

A method and system is provided for using backscattered data and known parameters to characterize vascular tissue. Specifically, methods and devices for identifying information about the imaging element used to gather the backscattered data are provided in order to permit an operation console having a plurality of Virtual Histology classification trees to select the appropriate VH classification tree for analyzing data gathered using that imaging element. In order to select the appropriate VH database for analyzing data from a specific imaging catheter, it is advantageous to know information regarding the function and performance of the catheter, such as the operating frequency of the catheter and whether it is a rotational or phased-array catheter. The present invention provides a device and method for storing this information on the imaging catheter and communicating the information to the operation console. In addition, information related to additional functions of the catheter may also be stored on the catheter and used to further optimize catheter performance and/or select the appropriate Virtual Histology classification tree for analyzing data from the catheter imaging element.

Gas sensor materials and methods are disclosed for preparing and using the same to produce gas sensor structures. Also disclosed are gas sensor structures and systems that employ these disclosed materials. A gas sense-enhancing metal such as platinum may be added to a gas sensitive metal oxide material in a manner that more highly disperses the added platinum than conventional methods so as to more effectively utilize the platinum at a lower concentration, thus achieving a more cost effective solution. An ink vehicle may also be used for deposition of a gas sensitive material (e.g. on the surface of integrated circuit) that is formulated to allow “burn-out” of ink vehicle components at relatively low temperatures as compared to conventional ink vehicles.
