  • Patent number: 6862705
    Abstract: An automated test system for testing electrical device I/O pad continuity includes a load board upon which the device under test (“DUT”) is mounted. The number of I/O pins on the DUT exceeds the number of direct testing channels available on the load board. The excess number of I/O pins are connected to boundary scan cells of one or more boundary scan devices. The boundary scan devices receive one or more test data input patterns and test control signals via connection points on the load board. The boundary scan devices, which are complaint with JTAG boundary scan testing standards, are utilized to indirectly test the electrical continuity from the I/O pads of the DUT to the external pins or solder balls of the DUT.

  • Publication number: 20040215714
    Abstract: A system and method is provided for user and command specific place based caching with cache validation, including a server; a database; a server cache; the server responsive to receiving a request message for generating a user-specific cache file name, accessing the server based cache with the file name to obtain a cached response message, validating the cached response message, generating a response message selectively from the cached response message if obtained and validated, and otherwise generating from the database and selectively caching the response message.

  • Publication number: 20040128271
    Abstract: A system for central refresh of a place includes a source place; a place type; a child place; each place comprising a plurality of place objects, each place object implemented as a document, logic and associated design note, each design note including a plurality of items; a subset of the items being content items descriptive of content of the objects; a central refresh execution module for determining whether an inherited place object is modified in a place by assigning to each item a sequence indicia indicative of change activity with respect to the item; generating and storing a stored checksum of sequence indicia generated for the content items; and responsive to a refresh operation with respect to the child place, calculating a refresh checksum of sequence indicia for the content items; and the central refresh execution module further responsive to the stored checksum and the refresh checksum being unequal for refreshing the child place.

  • Publication number: 20020188729
    Abstract: A collaboration control system and method for managing use of a plurality of resources includes a user information collection routine for collecting user account information for a user using the resources and creating an LDAP user account entry. A mirror routine automatically generates mirror persons from the user account entry and maintains the mirror persons within the resources to identify the user across the resources.

  • Patent number: 4282383
    Abstract: Cyclohexylbenzene and dicyclohexylbenzenes are converted to the corresponding hydroperoxides in the presence of t-butyl, cumene, or p-diisopropylbenzene hydroperoxides and a free radical initiator. The use of the combination of hydroperoxide and free radical initiator enables the reaction to be carried out at lower temperatures (80.degree.-105.degree. C.) than can be employed with hydroperoxides or free radical initiators alone and gives high (90%) selectivity and good conversion (20% or higher).

  • Patent number: 4202833
    Abstract: Isopropylphenyl esters are converted to di- or trihydric phenols via a novel autoxidation of the esters at high conversion rates to the corresponding hydroperoxyisopropylphenyl esters in the presence of a catalyst combination comprising at least two members selected from the group consisting of (i) a metal phthalocyanine; (ii) a di-tertiary alkyl peroxide; and (iii) a tertiary alkyl hydroperoxide.Rearrangement of the hydroperoxyisopropylphenyl esters to the corresponding hydroxyphenyl esters and the hydrolysis of the latter compounds provides the phenols in overall yields (from the starting esters) heretofore not obtainable. Novel bis(hydroperoxyisopropylphenyl)carbonates are described which are attractive intermediates for the intermediate bisphenol carbonate or the final hydroquinone hydrolysis product.
