  • Publication number: 20060042347
    Abstract: A creep forming tool modifies the shape of an aircraft component in the form of a wing skin portion. The tool includes a shaped surface defined by removable rib boards. The component is forced against the shaped surface, via a reusable intermediate plate. The shape of the shaped surface may be adjusted, if necessary, by replacing the rib boards with boards of a different shape.

  • Publication number: 20050206403
    Abstract: An apparatus and method for testing a semiconductor device in an AC test regime. The test apparatus includes a test plate capacitively couple to the signal terminals of the integrated circuit. The test plate is coupled to a test receiver circuit to receive and output the data signal detected at the test plate capacitively coupled to the signal terminals. Alternatively, the test plate is coupled to a test transmitter circuit to transmit data signals to signal terminals through the capacitively coupled test plate. A test unit can be coupled to the semiconductor device to evaluate the detected data signal against test criteria. Testing and evaluation is accomplished by capacitively coupling a test plate to a plurality of signal terminals. Data signals transmitted from a signal terminal and detected by the test plate or transmitted from the test plate and detected by the signal terminals are evaluated against a test criteria.

  • Publication number: 20050162203
    Abstract: A fast acting charge pump is provided which is suitable for use in a locked loop circuit where very short duration first and second adjustment pulses are produced by a phase detector. The first complement of the second adjustment pulses are used to switch the output of the charge pump through respective pairs of switching and associated biasing transistors, while a complement of the first and second adjustment pulses are respectively capacitively coupled to interconnection nodes of the pairs of switching and biasing transistors.

  • Patent number: 5981276
    Abstract: Packaging defective and packaging proficient HIV vectors are disclosed. These vectors can be used to establish HIV packaging defective cell lines, and to package desired genes. These cell lines can be used in developing a vaccine, HIV antibodies and as part of a system for gene transfer. The packaging proficient vector can be used to target HIV target cells.
