Abstract: Techniques for selectively filtering data are discussed herein. For example, a request to include data in an electronic message or a request to copy the data to a portable storage device may be received. If the data is sensitive data, the techniques may determine a software application that was opened or closed prior to receiving the request, or information that was accessed prior to receiving the request. The techniques may determine if including the data in the electronic message or copying the data to the portable storage device poses a security risk. If a security risk is identified, a task may be performed, such as alerting a network administrator, providing a notification to a user regarding the data, or preventing copying or transmission of the data.

Abstract: A composite comprises a polymer matrix and a luminophore dispersed therein. The composite is useful as a sensing film that is used as an optical sensor for oxygen measurement comprising the composite sensing film; a source of photons for photo-exciting the luminophores and a waveguide, transparent in the frequency range of the excitation photons, for guiding the excitation photons from the source to the composite sensing film; a detector for measuring properties of photons emitted from the luminophores. A system including a computer may be useful for coordinating the activities of the sensor.

Abstract: A software-based security agent that hooks into the operating system of a computer device in order to continuously audit the behavior and conduct of the end user of the computer device. The detected actions of the end user can be stored in a queue or log file that can be continuously monitored to detect patterns of behavior that may constitute a policy violation and/or security risk. When a pattern of behavior that may constitute a policy violation and/or security risk is detected, an event may be triggered. A frequency vector string matching algorithm also is disclosed. The frequency vector string matching algorithm may be used to detect the presence or partial presence of subject strings within a target string of alphanumeric characters. The frequency vector string matching algorithm could be used to detect typos in stored computer records or to search for records based on partial information.

Abstract: The invention provides gallium nitride material devices, structures and methods of forming the same. The devices include a gallium nitride material formed over a substrate, such as silicon. Exemplary devices include light emitting devices (e.g., LED's, lasers), light detecting devices (such as detectors and sensors), power rectifier diodes and FETs (e.g., HFETs), amongst others.

Abstract: A method of manufacturing a heterojunction device includes forming a first layer of p-type aluminum gallium nitride; forming a second layer of undoped gallium nitride on the first layer; and forming a third layer of aluminum gallium nitride on the second layer, to provide an electron gas between the second and third layers. A heterojunction between the first and second layers injects positive charge into the second layer to compensate and/or neutralize negative charge within the electron gas.

Abstract: A method of compensating resistivity of a near-surface region of a substrate includes epitaxially growing a buffer layer on the substrate, wherein the buffer is grown as having a dopant concentration as dependent on resistivity and conductivity of the substrate, so as to deplete residual or excess charge within the near-surface region of the substrate. The dopant profile of the buffer layer be smoothly graded, or may consist of sub-layers of different dopant concentration, to also provide a highly resistive upper portion of the buffer layer ideal for subsequent device growth. Also, the buffer layer may be doped with carbon, and aluminum may be used to getter the carbon during epitaxial growth.

Abstract: The invention includes providing gallium nitride materials including thermally conductive regions and methods to form such materials. The gallium nitride materials may be used to form semiconductor devices. The thermally conductive regions may include heat spreading layers and heat sinks. Heat spreading layers distribute heat generated during device operation over relatively large areas to prevent excessive localized heating. Heat sinks typically are formed at either the backside or topside of the device and facilitate heat dissipation to the environment. It may be preferable for devices to include a heat spreading layer which is connected to a heat sink at the backside of the device. A variety of semiconductor devices may utilize features of the invention including devices on silicon substrates and devices which generate large amounts of heat such as power transistors.

Abstract: A crop, measure and scale system and a measure and scale system are provided for use in preparing an original image for processing. The crop, measure, and scale system includes first and second corner members which define an infinitely adjustable image frame. Each corner member includes a pair of diverging arms, one arm being characterized as an abscissa arm and the other as an ordinate arm, each of which includes an internally facing edge. A calculating measure is mounted on one of the corner members, such calculating measure including a slide rule with a ruler which extends between opposite edges of the cropped image, and a slide which provides for calculation of a reduction/enlargement percentage based on a predetermined desired dimensional change. The measure and scale system includes the calculating measure described above joined to an elongate member.

Abstract: A global domination board game for a plurality of players having the object of total global domination by one of the players without excessive destruction of the planet. A game board has a map of a planetary surface divided into a plurality of continental powers, and further divided into a plurality of territories within each continental power. Each territory is identified as having a primary asset including population, resources or technology. A deck of cards is used which includes a territory card for each of the territories identified on the map of the game board and a plurality of wild cards. Players have a plurality of active playing pieces including pieces representing conventional forces, tactical weapon systems and strategic nuclear weapons. Players conduct simulated military attacks on territories occupied by opposing players.
