  • Patent number: 7076613
    Abstract: The invention provides a cache management system comprising in various embodiments pre-load and pre-own functionality to enhance cache efficiency in shared memory distributed cache multiprocessor computer systems. Some embodiments of the invention comprise an invalidation history table to record the line addresses of cache lines invalidated through dirty or clean invalidation, and which is used such that invalidated cache lines recorded in an invalidation history table are reloaded into cache by monitoring the bus for cache line addresses of cache lines recorded in the invalidation history table. In some further embodiments, a write-back bit associated with each L2 cache entry records when either a hit to the same line in another processor is detected or when the same line is invalidated in another processor's cache, and the system broadcasts write-backs from the selected local cache only when the line being written back has a write-back bit that has been set.

  • Publication number: 20060052745
    Abstract: The invention provides methods and apparatus for detecting an analyte in blood. The apparatus is particularly suited for bringing a sensor into direct contact with blood in vivo. The apparatus comprises a sensor that detects the presence of an analyte and an assembly means. The assembly means has a sensor end, wherein the sensor end of the assembly means is affixed to the sensor, and the assembly means is adapted for coupling with a venous flow device. By coupling with a venous flow device, the assembly means brings the sensor into direct contact with blood flowing through the venous flow device. Examples of venous flow devices that bring the sensor into direct contact with the blood of a subject include, but are not limited to, intravenous catheters and external blood loops, such as are used in extra corporeal membrane oxygenation or hemodialysis.

  • Patent number: 6811659
    Abstract: Disclosed is a method for microelectrogravimetrically depositing an electroactive species onto an electrode or a plurality of electrodes comprising dispensing a solution containing the electroactive species from a microdispenser to form a hanging drop of the solution and contacting the electrode with the hanging drop of the solution, wherein the electrode is electrically coupled with the microdispenser to form an electrochemical cell, and applying a potential to the electrochemical cell. The application of the potential effects deposition of the electroactive species onto the electrode. The method of the invention eliminates the need for immersion of the electrode in a bath, reduces the volume of solution required by a factor of at least 10-100, and avoids uneven depletion of various components of the solution over successive applications.

  • Patent number: 6673313
    Abstract: A method for sterilizing the interior of a diffusion restricted area by introducing a sterilant in a chamber, condensing the vapor, reducing the pressure in the chamber to revaporize the condensed vapor, and maintaining the device in the chamber until the device is sterilized. The sterilant has a vapor pressure less than the vapor pressure of water and is preferably hydrogen peroxide. The pressure in the chamber while maintaining the device in the chamber may be held constant, varied, or increased. Plasma may additionally be introduced into the chamber to improve the rate of sterilization.

  • Publication number: 20030235511
    Abstract: A chemical vapor sterilization process is enhanced by concentrating a germicide via exploitation of the difference between the vapor pressures of the germicide and its solvent. A diffusion restriction can be placed into the diffusion path to assist this process and the path then opened to provide rapid diffusion of the thus concentrated germicide.

  • Patent number: 6599471
    Abstract: A method for determining and sterilizing a load in a sterilization chamber. A small amount of sterilant is introduced into the sterilization chamber and the concentration of sterilant is measured. The load of equipment to be sterilized is determined from the concentration of sterilant, and more sterilant is added, if necessary, based on the load. The process is repeated, if necessary, until the load is sterilized. The sterilant is preferably hydrogen peroxide, and the concentration of hydrogen peroxide is preferably determined by a spectrophotometric method in the infrared or ultraviolet regions. By monitoring the sterilant concentration and adding more as needed, the equipment in the chamber can be sterilized efficiently without exposing it to high concentrations of sterilant which could damage the equipment or leave too much residual on the equipment.

  • Patent number: 6589481
    Abstract: Various forms of apparatus and methods for pretreating and sterilizing a lumen with a peroxide solution prior to sterilization of the interior of the lumen by exposing the lumen to reduced pressure and, optionally, plasma in a sterilization chamber. The pretreatment is preferably done before placing the lumen in the sterilization chamber. The method also includes exposure of the exterior of the lumen to peroxide vapor to sterilize the exterior of the lumen. Pretreatment of the interior of the lumen with liquid peroxide greatly improves the efficiency of sterilization of the interior. Exposure of the lumen to plasma reduces the time required for sterilization.

  • Publication number: 20030113477
    Abstract: A device, and its production method, the device has a substrate and a coating composition, the coating composition being formed by the gas phase or plasma polymerization of a gas comprising at least one organic compound or monomer. The polymerization is carried out using a pulsed discharge having a duty cycle of less than about ⅕, in which the pulse-on time is less than about 100 msec and the pulse-off time is less than about 2000 msec. The duty cycle can also be varied, thus the coating composition can be gradient layered accordingly. The device has a coating composition which is uniform in thickness, pin-hole free, optically transparent in the visible region of the magnetic spectrum, permeable to oxygen, abrasive resistant, wettable and biologically non-fouling.
