Abstract: A coolant circuit for cooling of an engine in a power system. The coolant circuit includes an inlet line and an outlet line. The coolant circuit further includes a heat exchanger with a plurality of heat exchanging elements. The coolant circuit also includes a bypass line disposed in parallel to the heat exchanger, between the inlet line and the outlet line. A control valve is disposed in the coolant circuit regulating the flow of a coolant, such that the coolant flows through the heat exchanger and the bypass line when the control valve is in a fully open position.

Abstract: A method of forming a metal coating on surfaces of internal passages of a turbine blade includes, in an exemplary embodiment, the steps of positioning the turbine blade in a CVD chamber, coupling a reagent gas manifold to at least one internal passage inlet, and coating the surfaces of the at least one internal passage by a CVD process using metal coating reagent gases to form a metal coating on the surfaces of the at least one internal passage.

Abstract: A vehicle fleet management information system identifies location and direction of movement of each vehicle in a fleet in real-time, and automatically reports such information, as well as status of predetermined events in which the vehicle is engaged, directly to the fleet manager. Each fleet vehicle has an assigned time slot to transmit its reporting information over a communications network without interfering with transmissions from other vehicles in their own respective time slots. A timing control phase lock loop (PLL) provides precise time synchronization for timing corrections from a global positioning system (GPS) based time reference. A dual band full-duplex interface of the network has TDMA on one-half and broadcast on the other half. Microprocessor time processing units in components of the network perform precise clock synchronization. Space diversity performed on received vehicle transmitted messages avoids data corruption.

Abstract: A vehicle fleet management information system identifies location and direction of movement of each vehicle in a fleet in real-time, and automatically reports such information, as well as status of predetermined events in which the vehicle is engaged, directly to the fleet manager. One aspect relates to automated reporting of status of a ready mix slurry material truck having a mixer drum. A sensor detects the begin pour event by detecting the mixer drum being run in a discharge direction.

Abstract: A method for at least partially coating a surface of an object with a layer of platinum. The method includes applying a platinum precursor material to the object surface, evaporating the platinum precursor material from the object surface such that a residue comprising platinum remains on the surface, and heating the object such that the residue evaporates and re-deposits on the object surface as a layer comprising platinum.

Abstract: A process for protecting a thermal barrier coating. The process entails applying to a surface of the coating a liquid containing one or more of aluminum alkoxides, aluminum beta-diketonates, aluminum carboxylates, and aluminum alkyls. The liquid is applied so as to form a liquid film on the surface, and has viscosity and wetting properties that cause the liquid to infiltrate porosity within the coating beneath its surface. The coating is then heated to convert the alumina precursor to alumina. A first portion of the alumina forms a surface deposit on the coating surface, while a second portion of the alumina forms an internal deposit within the porosity of the coating. The surface deposit overlying the coating is available for sacrificial reaction with CMAS, and the internal deposit maintains a level of CMAS protection in the event the surface deposit is breached or lost through spallation, erosion, and/or consumption.

Abstract: A wireless gateway is provided that connects mobile and remote assets or employees to business enterprise users through multiple wireless networks and the Internet by using web served applications. The central core of the gateway is a location aware business component that sends and receives location based information to and from remote and mobile assets and applies business logic to the location data to enhance and automate business applications run by the enterprise user. This functionality considerably exceeds that of a traditional wireless gateway, which simply manages messages passed through multiple wireless networks but does nothing with the content of the messages. The business logic component provides a common interface and protocol for handling location information and allows applications that follow the protocol to interface with the gateway to take advantage of location information by using location data to trigger events or to tag events, messages, or other data.

Abstract: An optical fiber terminus includes an elongated body with a passage along a central axis for receiving a portion of an optical fiber cable therethrough and an indexing section. A ferrule is secured to the body and has an end portion of said optical fiber cable therein. A collar is positioned on the elongated body and has an engagement section for engaging the indexing section. The collar is movable along the axis between first and second operative positions. In the first operative position relative rotational movement between the collar and the body is prevented and in the second operative position the collar may rotate relative to the body. A biasing member is provided to bias the collar towards the first operative position.

Abstract: An optical fiber connector includes a connector housing having first and second generally parallel, spaced apart first and second faces and at least one generally cylindrical receptacle for removably receiving an optical fiber terminus therein. An optical fiber terminus is located within the receptacle and includes an elongated body with a passage along a central axis for receiving a portion of an optical fiber cable therethrough. The body further includes an indexing section, and a ferrule secured to the body and having an end portion of said optical fiber cable therein. A collar is positioned on the elongated body and has an engagement section for engaging the indexing section. The collar is movable along the axis between first and second operative positions. In the first operative position relative rotational movement between the collar and the body is prevented and in the second operative position the collar may rotate relative to the body.

Abstract: A high-performance connector for optical fibers includes a cylindrical ceramic or metallic ferrule installed in a structure. This structure is positioned in a non-plastic (metallic system) base member to form a fiber holder. This overall generally cylindrical structure includes a small passageway along its central axis for holding an optical fiber. This entire structure is mounted within the non-plastic housing that includes an opening at one end thereof from which the ceramic ferrule protrudes. A cylindrical spring that is integral to the ferrule support structure and interacts with an interior surface of the surrounding structure via a secondary piece of the cylindrical structure urges the ceramic ferrule outward from the opening in the housing. The housing includes a metallic leaf-spring latch which is located on a single surface thereof, which is manually operable and used to lock the connector to an associated receptacle.

Abstract: A coating system for reducing the tendency for hydrocarbon fluids, such as fuels and oils, to form carbonaceous deposits that adhere to fluid containment surfaces. The coating system combines an outermost layer of platinum with an inner ceramic barrier layer of silica and/or tantala. The platinum layer catalyzes the hydrocarbon fluid to form particles of carbonaceous gum substances, and the ceramic barrier layer seals the containment surface from the hydrocarbon fluid to eliminate attachments points for deposits and inhibit interdiffusion between the platinum layer and the containment surface. The invention also encompasses a coating apparatus and process for depositing the coating system.

Abstract: A vehicle fleet management information system for identification of location and direction of movement of each vehicle in the fleet in real-time and automatic communication directly with management offices to report its location and heading, and status of predetermined events in which the vehicle may be engaged. One example is a cement delivery truck which monitors location, speed and status information such as start pour, pouring, end pour, wash and leave job, and automatically transmits this information with a management office without requiring affirmative action by the vehicle operator.
