Abstract: An optical barcode and/or RFID reader having at least two sets of illuminating LEDs that are directed toward a target object to reflect whether the barcode and/or RFID reading was successful or unsuccessful. The reader is provided with a set of red LEDs and a set of green LEDs for illuminating targets, such as barcodes or RFID tags. In addition to using these LEDs to illuminate the target, the reader will illuminate the target with a particular color of light to signify a successful read, such green light, or an unsuccessful read, such as red light. A third color may be provided to indicate a successful RFID interrogation, such as blue light. The reader thus uses the built-in illumination LEDs to cast differently colored light on the target, rather than having to provide additional LEDs in a user interface positioned on the housing of the reader.

Abstract: A c-axis-oriented HAP thin film synthesized by seeded growth on a palladium hydrogen membrane substrate. An exemplary synthetic process includes electrochemical seeding on the substrate, and secondary and tertiary hydrothermal treatments under conditions that favor growth along c-axes and a-axes in sequence. By adjusting corresponding synthetic conditions, an HAP this film can be grown to a controllable thickness with a dense coverage on the underlying substrate. The thin films have relatively high proton conductivity under hydrogen atmosphere and high temperature conditions. The c-axis oriented films may be integrated into fuel cells for application in the intermediate temperature range of 200-600° C. The electrochemical-hydrothermal deposition technique may be applied to create other oriented crystal materials having optimized properties, useful for separations and catalysis as well as electronic and electrochemical applications, electrochemical membrane reactors, and in chemical sensors.

Abstract: The present invention relates to a method of disaster recovery in data processing systems and to a recovery system. The invention allows for easy, fast and reliable recovery of a data processing system in a disaster situation. Unmodified backup data is stored to a target data processing system, the hardware of the target data processing system being different from the hardware of the source data processing system, from which the backup data originated. The stored backup data is then adapted to the hardware of the target data processing system by a remote recovery system using previously obtained reference data.

Abstract: A device for attachment to a conventional type of ladder for holding tools and other diverse items in a position for convenient access by a workman on the ladder is described in two embodiments. In both embodiments the device includes a rigid, linearly elongated member carrying a pair of projections having free ends in opposing, spaced relation, the distance between the free ends being selectively adjustable by relative movement of the projections along an axis parallel to a spaced from the axis of the elongated member. In a first described embodiment, the elongated member is formed by a pair of tubular, telescopingly engaged members with one of the projections fixedly mounted to opposite ones of the pair of members. In the preferred embodiment, the elongated member is a one-piece rod with one of the projections fixedly connected thereto and the other projection mounted to a bracket which is slidable along the rod.

Abstract: A method of measuring the state of flow above an airfoil using an estimation of the velocity field based on a combination of Particle Image Velocimetry PIV and multiple surface pressure measurements processed through a POD/mLSE algorithm. Integral to the POD/mLSE algorithm is the estimation of the global POD coefficients. The utility of these time dependent coefficients, which are estimated from surface pressure only, are demonstrated in a simple proportional feedback loop (as the time series to drive the actuators) to keep the flow attached. This method requires realistic feedback flow control since surface measurements and not inflow measurements are required for practical applications. The estimation method works well with dynamic strain on flexible bodies and is not limited to estimation from pressure only.

Abstract: The present invention provides a system and method for automatically refining ontology within a specific context. The system comprises: a rich context extractor for discovering a semantics relationship conflict existing between an original ontology schema and application data; and an ontology schema and mapping refiner for refining the original ontology schema based on the semantics relationship conflict discovered by the rich context extractor, and creating a new mapping between the refined ontology schema and a data schema of the application data. According to the invention, users can save a lot of work of manual refinement, since the ontology schema is automatically refined based on contexts in the application data.

Abstract: A semiconductor device including at least one gate terminal in operational contact with an active layer or top surface of the semiconductor substrate includes a deposited layer of boron phosphide covering the gate terminal and at least a portion of the active layer or the top surface next to and extending from the gate terminal. According to an aspect, the layer of boron phosphide is deposited by a chemical vapor deposition (CVD) process. The boron phosphide layer will have a thickness less than or equal to about 10 microns. The boron phosphide provides a heat spreading coating across the die surface, thus increasing the surface area that conducts the heat from the die. Since the boron phosphide coating is in intimate contact with the gate terminal(s) and the immediately adjacent passivation surfaces of the device, generated heat can rapidly spread away from the active junction or channel.

Abstract: A system and method for using gradient nanotopography to increase mammalian cell attachment and cell confinement on surfaces. A surface platform consisting of a thin film of gold possessing a gradient of topography on the surface and self-assembled monolayers of alkanethiols presenting desired functional groups is formed. A gradient in the chemical properties is induced in the terminal groups of the monolayer because of the continuous increase in the surface area and the anisotropy of gold film structure. The gradient nanotopraphy provides simultaneous control of two key properties, the presentation of the terminal functional groups and a continuous increase in the surface density of functional groups on the surface. This control provides for drug screening assays using adherent cell-based experiments.
