  • Abrasive article having a line of weakness
    Patent number: 8506364
    Abstract: A coated abrasive article (1) comprises a backing (3) having an abrasive coating (5) on one side, an attachment layer (7) on the other side of the backing, and a line of weakness (9) that does not penetrate the front face of the abrasive coating (5). The line of weakness, which may be formed using a laser beam, comprises a through-cut (11) in the attachment layer (7) and perforations (13) in the backing (3), and permits one part of the abrasive article (1) to be separated from another part. Alternatively, the abrasive article can be used in its original form.

  • Method and apparatus for circuit board testing with controlled backdrive stress
    Patent number: 5127009
    Abstract: An automated circuit board testing system, for performing in-circuit, functional or cluster tests, takes backdrive stress into account in selecting appropriate isolation methods for digital devices during the design of the test protocol. In other words, the design of the test includes an analysis of the circuit board and its components, and of the available methods to isolate the device- or function-under-test from the rest of the circuit board. The analysis includes a calculation of stress currents on upstream components resulting from backdriving, and a selection of methods from those available which will produce stress currents below a pre-selected level. In another aspect of the invention, the safe maximum run-time for the test using the available methods is computed.
