Abstract:
A system and method for providing access to a video display for multiple devices. Various aspects of the present invention may comprise receiving, at a video display system, a first video data signal through a first data communication interface and a second video data signal through a second data communication interface. A processor module may process the first and second video data signals to generate video information of first and second display windows in a composite display. For example, the processor module may transform and translate video information to fit display windows. The processor module may, for example, generate an output video signal comprising information of the first window and information of the second window. Such a signal may, for example, be utilized to drive an output display showing the first and second windows. Various aspects may also provide method steps and apparatus for controlling aspects of the displayed windows.
Abstract:
A system and method for sharing a view between systems in a dynamic wireless communication network. Various aspects of the present invention may comprise a first system communicating information of a view to a display resource of the first system. The first system may establish a two-way wireless communication link between the first system and a second system in the dynamic wireless communication network. The second system may, for example, communicate a request to the first system for the first system to share a view with the second system. The first system may, for example, receive such a request and respond to such a request by communicating information of a view to the second system. The second system may then communicate information of the view to a display resource of the second system. Various aspects may comprise the first and second systems communicating view modification information between the systems.
Abstract:
A method of controlling process variables, for a fiberizing assembly including a rotary fiberizing disk in the manufacture of fibers from a high temperature, molten, clear or translucent, thermoplastic, fiberizable material, utilizes an optical sensor assembly. The optical sensor assembly includes a water-cooled optical fiber sensor probe which, in effect, only gathers light emitted from the external sidewall surface of the rotary fiberizing disk. The light is conducted from the probe to an electronic unit that converts the light energy into a temperature value. This temperature value is used to monitor the process and to make any changes in process variables, such as but not limited to heat input to the fiberizing disk, rate of rotation of the fiberizing disk, burner air/fuel ratio, required to produce fibers having desired fiber properties.
Abstract:
A modular materials characterization apparatus includes a sensor array disposed on a substrate, with a standardized array and contact pad format; electronic test and measurement apparatus for sending electrical signals to and receiving electrical signals from the sensor array; an apparatus for making electrical contact to the sensors in the standardized array format; an apparatus for routing signals between one or more selected sensors and the electronic test and measurement apparatus and a computer including a computer readable having a computer program recorded therein for controlling the operator of the apparatus. The sensor array is preferably arranged in a standardized format used in combinatorial chemistry applications for rapid deposition of sample materials on the sensor array. The interconnection apparatus and sensor array and contact pad allow measurement of many different material properties by using substrates carrying different sensor types, with only minor modifications if any to the electronic test and measurement apparatus and test procedures. By using a sensor array that is separate from the electronic apparatus, and by including standardized contacting and signal routing apparatuses, the apparatus creates a modular “plug-and-play” system that eliminates the need for multiple materials characterization machines, and eliminates the need for application-specific active circuitry within the sensor arrays themselves. Further, the modular sensor array system can characterize large numbers of material samples rapidly, on the order of at least 50 samples per hour, reducing the time needed for screening of materials libraries.

Abstract:
Methods, systems and devices are described for rapid characterization and screening of liquid samples to determine properties (e.g., particle size, particle size distribution, molar mass and/or molar mass distribution) thereof with static light scattering and/or dynamic light scattering. The liquid samples can be solutions, emulsions, suspensions or dispersions. One method, includes providing a vessel containing a liquid sample having an exposed surface that defines a gas-liquid sample interface, and analyzing the sample by light scattering methods that include transmitting light through the gas-liquid sample interface into the sample, and detecting light scattered from the sample or from a component thereof. Additional methods are directed to characterizing a plurality of liquid samples or components thereof. The methods, systems, and devices have applications in high-throughput screening, and particularly, in combinatorial materials research and in industrial process control.
Abstract:
A method and apparatus for measuring properties of a liquid composition includes a mechanical resonator, such as a thickness shear mode resonator or a tuning fork resonator, connected to a measurement circuit. The measurement circuit provides a variable frequency input signal to the tuning fork, causing the mechanical resonator to oscillate. To test the properties of a liquid composition, the mechanical resonator is placed inside a sample well containing a small amount of the liquid. The input signal is then sent to the mechanical resonator and swept over a selected frequency range, preferably less than 1 MHz to prevent the liquid being tested from exhibiting gel-like characteristics and causing false readings. The mechanical resonator's response over the frequency range depends on various characteristics of the liquid being tested, such as the temperature, viscosity, and other physical properties. Particular mechanical resonators, such as tuning fork resonators, can also be used to measure a liquid composition's electrical properties, such as the dielectric constant and conductivity, because the tuning fork's structure allows a high degree of electrical coupling between the tuning fork and the surrounding liquid. The mechanical resonator can be covered with a coating to impart additional special detection properties to the resonator, and multiple resonators can be attached together as a single sensor to obtain multiple frequency responses. The invention is particularly suitable for combinatorial chemistry applications, which require rapid analysis of chemical properties for screening.
Abstract:
An apparatus for characterizing a library is provided in which the library contains an array of elements and each element contains a different combination of materials. The apparatus includes an x-ray beam directed at the library, a chamber which houses the library and a beamline for directing the x-ray beam onto the library in the chamber. The chamber may include a translation stage that holds the library and that is programmable to change the position of the library relative to the x-ray beam and a controller that controls the movement of the translation stage to expose an element to the x-ray beam in order to rapidly characterize the element in the library. During the characterization, the x-ray beam scatters off of the element and a detector detects the scattered x-ray beam in order to generate characterization data for the element.

Abstract:
A thrust control valve which is operable to direct a gas supply to provide thrust is disclosed. The gas supply to obtained from a hot gas generator eg a rocket motor combustion chamber, and is directed through a nozzle by the operation of a plunger mounted within a pressure chamber. The pressure in the pressure chamber is controlled by the operation of a solenoid-operated poppet valve which moves between two positions to either pressurize the chamber ie sealing the nozzle with the plunger to provide no thrust, or to de-pressurize the chamber ie allowing gas from the gas supply to exit via the nozzle thereby providing thrust.
