Publication number: 20100097682Abstract: A beam delivery system for treating target tissue that includes an input for receiving a light beam, a variable attenuator for providing variable attenuation of the light beam, a power and wavelength detection assembly, a spot size adjustment assembly, and a controller. The power and wavelength detection assembly measures the power level of the beam, and detects when unwanted wavelengths are present in the light beam. The spot size adjustment assembly selectively feeds the beam through different optical fibers to achieve different spot sizes of the beam. The controller controls the variable attenuator, the power and wavelength detection assembly, and the spot size adjustment assembly to achieve the desired power and wavelength, and beam spot size.Type: ApplicationFiled: October 16, 2008Publication date: April 22, 2010Inventors: David G. Angeley, Steven S. Christensen, Michael J. Simoneau, Phillip H. Gooding

Publication number: 20080288597Abstract: A method and program product for preventing distribution of an e-mail message. The method includes generating an e-mail message to one or more recipients using an e-mail application installed on a sender e-mail client and selecting a non-distribution option provided by a non-distribution plug-in installed on the sender e-mail client. The method further includes encrypting the message using a recipient public key and a plug-in secret key provided by the plug-in before sending the message. Further, the method includes providing a hyperlink to a website for installing a correct version of the plug-in on a recipient e-mail client for decrypting and displaying the message. Moreover, the method includes decrypting the message using a recipient private key and using the plug-in secret key provided by the plug-in and modifying the recipient e-mail client, such that one or more distribution functions are disabled, preventing distribution of the message by the recipient.Type: ApplicationFiled: May 17, 2007Publication date: November 20, 2008Applicant: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Eric S.

Patent number: 7010733Abstract: A method for reducing Pin Count Test design and test that allows parametric test patterns for high pin count ASICs to be applied using low pin count testers. The same boundary scan structure used to isolate the test of internal logic to a small number of test I/O is also used to apply parametric external I/O tests to the ASIC's functional I/O. The parametric tests are banked into pin groups and applied on the same low pin count tester used for the internal logic tests.Type: GrantFiled: October 9, 2002Date of Patent: March 7, 2006Assignee: International Business Machines CorporationInventors: Robert W. Bassett, Garrett S Christensen, Michael L. Combs, L. Owen Farnsworth, Pamela S. Gillis

Publication number: 20050236300Abstract: Disclosed is a process for preparation of compositions having utility as well fluid base oils. The process involves metathesis of alpha-olefins followed by isomerization of the metathesis products. The base oils resulting from the process of this invention are environmentally friendly in that they are only mildly toxic to marine life and have very low pour point temperatures. These properties make the base oils ideal candidates for use as components of well fluids for cold climates and offshore applications.Type: ApplicationFiled: June 28, 2005Publication date: October 27, 2005Inventors: Fred Twu, S. Christensen, Scott Hensey, William Rost

Publication number: 20040199618Abstract: The disclosure is directed to a data replication policy engine for use with a storage network. The storage network includes a first storage network, a second storage network and a wide area network. The data replication policy engine includes a monitor and analyze aspect and a corrective action aspect. The monitor and analyze aspect is adapted to be operably coupled to at least a subset of components selected from the storage network. The monitor and analyze aspect is also adapted to monitor the status of the selected components and the storage network while the storage network is operating. Still further, the monitor and analyze aspect is adapted to describe problems discovered in the selected components and the storage network. The corrective action aspect is operably coupled to the monitor and analyze aspect and to at least the subset of components selected from a first storage area network, the second storage area network and the wide area network.Type: ApplicationFiled: February 6, 2003Publication date: October 7, 2004Inventors: Gregory John Knight, Brian Derek Davies, Kent S.

Patent number: 6700467Abstract: An operating mechanism controls and trips a separable contact structure arranged in a protected circuit. The mechanism includes a frame, a drive member pivotally coupled to the frame, a spring pivotally connecting the drive member to a drive connector, an upper link pivotally seated on the drive connector, a lower link member pivotally coupled to the drive connector, a crank member pivotally coupled to the lower link member for interfacing the separable contact structure, and a cradle member pivotally secured to the frame and pivotally securing the upper link. The cradle member is configured for being releasably engaged by a latch assembly, which is displaced upon occurrence of a predetermined condition in the circuit such as a trip condition. The mechanism is movable between a tripped position, a reset position, an off position, and an on position. Spacers are operatively positioned between movable members, and protrusions are operatively formed on the enclosure of the contact structure.Type: GrantFiled: September 20, 2001Date of Patent: March 2, 2004Assignee: General Electric CompanyInventors: Roger N.
