  • Publication number: 20070168379
    Abstract: A screen shot of a window of a program is taken. A computer program queries data structures that are a source for aspects of the screen shot. The program objects return text strings associated with the window to the computer program. The computer program associates a unique identifier, the screen shot and the text strings together into a second data structure.

  • Publication number: 20070083855
    Abstract: A preprocessor places unique identifiers on each output phrase of a source code to produce a modified source code. Modified source code is exercised by test cases to produce a body of output images that are each added to digest files. A preprocessor character recognizes the images. This permits graphical representations of each instance of the output phrases to be traced to the source file from which the graphical representations originate. The output phrase and unique identifiers are added as text to each digest file so as to ease later search and retrieval of the image. A translator uses a matchtool to locate and display specific contextual images while editing the source file wherein the image is discovered by matching an output phrase in the source file with the text of a digest file.

  • Patent number: 7186940
    Abstract: An electrical switch includes two fixed contacts and a moving contact supported for movement between an ON position in contact with the fixed contacts and an OFF position out of contact with the fixed contacts, and an operating mechanism for moving the moving contact. The operating mechanism has an operating member, a contact mover supported for moving the moving contact upon movement by the operating member, and a spring-loaded device located between the operating member and the contact mover for movement by the operating member past a transitional condition of maximum strain to flick the contact mover between the operating positions of the contact mover.

  • Publication number: 20070038982
    Abstract: A method, apparatus, and computer program instructions for automatically performing test builds of natural language translated files for a software product. When a translated file is received from a translator, a test build of the translated file is executed in a translation test build environment, wherein the translation test build environment is separate from the main software product build environment. A determination is made as to whether the test build of the translated file is successful. If the test build is successful, the translated file is submitted to the main software product build environment. If the test build is unsuccessful, a log file containing error information is sent to the translator to allow the translator to fix compile errors identified in the translated file and resubmit the translated file to the translation test build environment.

  • Publication number: 20060112984
    Abstract: The highly mismatched alloy Zn1-yMnyOxTe1-x, 0?y<1 and 0<x<1 and other Group II-IV-Oxygen implanted alloys have been synthesized using the combination of oxygen ion implantation and pulsed laser melting. Incorporation of small quantities of isovalent oxygen leads to the formation of a narrow, oxygen-derived band of extended states located within the band gap of the Zn1-yMnyTe host. With multiple band gaps that fall within the solar energy spectrum, Zn1-yMnyOxTe1-x is a material perfectly satisfying the conditions for single-junction photovoltaics with the potential for power conversion efficiencies surpassing 50%.

  • Patent number: 6989503
    Abstract: A trigger assembly for an electric power tool includes a switch for electrical connection to the power tool for controlling operation of the power tool, and a trigger coupled with the switch for operating the switch. The trigger is pivotable about an upper end between an outer position in which the switch is open and an inner position in which the switch is closed. Also included is a locking member located adjacent the lower end of the trigger for locking the trigger in the outer position. The locking member is movable from a locking position, locking the trigger in the outer position, to an unlocking position releasing the trigger.

  • Patent number: 6861605
    Abstract: An electrical switch includes an operating member carrying moving contacts which face, in opposite directions, two rows of fixed contacts. The operating member moves the moving contacts into and out of contact with the fixed contacts. Each moving contact may have opposite ends for contacting two adjacent fixed contacts on a corresponding side of the operating member. Springs provided between the moving contacts and corresponding side of the operating member bias the contact ends into contact with the corresponding rows of fixed contacts.
