  • Publication number: 20060167773
    Abstract: The orders collected during an auction form an auction pool. The fill for orders in the auction pool is established without setting an auction settlement price (ASP) for the contracts in the auction pool. The ASPs for contracts in the qualified pool are then set based on the fill. Both the process for establishing the fill for orders and/or the process for setting the ASPs preferably are based on LP and/or QP optimizations.

  • Publication number: 20060063966
    Abstract: An isolation unit for a patient bed is provided. The bed has a platform, atop which a patient may rest. The isolation unit firstly includes a frame having an upper frame positioned above the platform and a lower frame formed in a perimeter of or positioned around the platform. The bed further includes at least one air supplier on the upper or lower frame for supplying air towards the lower or upper frame respectively to form an air curtain, and at least one air extractor positioned on the lower or upper frame respectively for extracting the air to increase the strength of the air curtain. The air curtain extends between the upper frame and the lower frame and at least partly defines a space between the upper frame and the platform.

  • Publication number: 20050246612
    Abstract: A file system enables the real-time correction of detected corruptions to on-disk data. An enhancement to a file system responds in real time to file system corruptions detected on a running volume, and repairs the corruptions at the point where the file system detects them. Upon detection of a corruption by the file system, the system enhancement records information describing the nature of the corruption. A repair scan is defined for each type of corruption encountered. Repair scans can be run at the top level of execution in the current thread in which the corruption is detected, or they may require a dedicated thread to service the repair operation.

  • Patent number: 6806740
    Abstract: A linear phase detector includes first, second and third latches connected in series, each of the latches having a data input, a data output and a clock input, and further includes reference signal generation circuitry and error signal generation circuitry. The reference signal generation circuitry has at least a first input coupled to the data output of the second latch and a second input coupled to the data output of the third latch. The error signal generation circuitry has at least a first input coupled to the data input of the first latch and a second input coupled to the data output of the second latch, and is configured to generate an output that is indicative, relative to the reference signal, of the phase error of a clock signal.
