  • Management of Deletion Requests for Related Documents in a Content Management System
    Publication number: 20090327262
    Abstract: A method and system for the management of deletion requests for related documents in a content management system. When a user requests to delete a related document associated with a record in the content management system, the request determines whether there are other documents associated with the record, collects the documents and determines if any of the collected documents are parent documents, removes the association between each collected document and the record, and initiates a deletion process to delete the parent documents.

  • Memory System with Calibrated Data Communication
    Publication number: 20090327789
    Abstract: A system includes a first integrated circuit device and a second integrated circuit device. The first device transmits a data sequence to the second integrated circuit device, and the second device samples the data sequence to produce receiver data. The second device then transmits the receiver data back to the first device. Within the first integrated circuit device, a comparison between the data sequence and the receiver data is performed, and based on the comparison, the first device generates information representative of a calibrated timing offset. The first device uses the information representative of the calibrated timing offset to adjust timing associated with transferring write data from the first integrated circuit to the second integrated circuit.

  • METHOD AND APPARATUS FOR FRAME REDIRECTION IN A STORAGE AREA NETWORK ENVIRONMENT
    Publication number: 20090313415
    Abstract: Embodiments according to the invention relate to frame redirection, which includes methods to intercept and re-route traffic between an initiator and a target. When a frame is redirected, an initiator issues a frame to the target, but the frame is received by a virtual target in a redirection switch by allowing the redirection switch to use the WWN of the actual target. From the perspective of the initiator, the target resides on the redirection switch. From the redirection switch, the frame is sent to the actual target by allowing the redirection switch to use the identity of the initiator. In other words, the redirection switch presents the WWN of the initiator to the target when the redirected frame is sent to the target. From the perspective of the target, the frame is received as if it originated at the initiator.

  • METHOD AND SYSTEM FOR GENERATING A BEAM OF ACOUSTIC ENERGY FROM A BOREHOLE, AND APPLICATIONS THEREOF
    Publication number: 20090310441
    Abstract: A compact array of transducers is employed as a downhole instrument for acoustic investigation of the surrounding rock formation. The array is operable to generate simultaneously a first acoustic beam signal at a first frequency and a second acoustic beam signal at a second frequency different than the first frequency. These two signals can be oriented through an azimuthal rotation of the array and an inclination rotation using control of the relative phases of the signals from the transmitter elements or electromechanical linkage. Due to the non-linearity of the formation, the first and the second acoustic beam signal mix into the rock formation where they combine into a collimated third signal that propagates in the formation along the same direction than the first and second signals and has a frequency equal to the difference of the first and the second acoustic signals.

  • DEVICE FOR QUANTIFICATION OF RADIOISOTOPE CONCENTRATIONS IN A MICRO-FLUIDIC PLATFORM
    Publication number: 20090302228
    Abstract: A micro-fluidic device has a micro-fluidic circuit layer and a charged-particle detection layer disposed proximate the micro-fluidic circuit layer. The micro-fluidic device is constructed to provide a two-dimensional image of charged-particle emissions from a sample within the micro-fluidic circuit layer while in operation. A method of quantification of radioactivity in a biological sample includes directing a fluid containing the biological material into a microfluidic device, detecting charged particles emitted from the biological material with a two-dimensional imaging sensor, and forming a two-dimensional image over time corresponding to radioactivity of the biological sample.
