  • Patent number: 6400453
    Abstract: An instrument for analyzing and dispensing objects larger than about 70 &mgr;m in diameter is based on a flow cytometer with a novel fluidic switch arrangement for diverting a portion of a sample stream in response to detector signals in a flow cell. The instrument is particularly adapted for dispensing multicellular test organisms like nematodes or large microspheres for use in screening large libraries of potential pharmaceutical agents. Hydrodynamic focussing is used to center and align the objects in the flow cell. The objects pass through a sensing zone where optical or other characteristics of the objects are detected. The detector signals are processed and used to operate a fluidic switch that is located downstream from the sensing zone. The fluid stream containing the detected objects emerges from the flow cell into air where a fluid stream controlled by the fluidic switch diverts portions of the stream containing no sample objects or sample objects not meeting predetermined characteristics.

  • Patent number: 6397371
    Abstract: A general methodology for worst-case analysis of systems with discrete observable signals is disclosed. According to one embodiment, a signature &sgr; is chosen and a &sgr;-abstraction F is created, based on the system and the particular property to be analyzed. This procedure requires a user to facilitate the creation of an appropriate signature and &sgr;-abstraction. Next, for a given length of time T, a signature s is determined. From the signature s the worst-case boundary conditions are determined. The methodology may also be applied to timing analysis of embedded systems implemented on a single processor. The procedure calculates a time T which is an upper bound on the time a processor can be busy (i.e. busy period). Thus, for the busy-period analysis, the time T is no longer fixed. As in the first embodiment, a signature &sgr; is selected and a &sgr;-abstraction F is created. A workload function R is chosen, and a signature s and time T are calculated.

  • Patent number: 6393517
    Abstract: A method of recording data, including audio data and control data, to a SCSI drive having both a write mode and a write-verify mode, comprises the steps of initializing the drive to a write mode, receiving recording data and organizing the recording data into SCSI request blocks (SRBs), and checking each SRB to see if it contains a write block. If the SRB includes either no write block or is audio data, then the SRB is recorded by the drive. However, if the SRB includes a write block and no audio data, then the SRB is converted from a write block to a write-verify block and recorded by the drive.

  • Patent number: 6385759
    Abstract: A method used inside a static timing analyzer, or any timing-driven tool, to reduce the memory required to store the timing values. A static timing analyzer stores the arrival times and the required times at every pin of a digital circuit design. As circuit density increases, the number of pins increases proportionately. In order to be able to handle such large designs it is desirable to keep the memory requirement to a minimum, without compromising the performance. The technique presented herein produces significant memory requirement reduction for design with multiple clocks, or multi-cycle paths, with very little performance penalty. In a preferred embodiment of the invention, the method is carried out by the steps of: 1) Setting and propagating source triggering edges forward; 2) Determining target triggering; 3) Propagating the target triggering edges backward; 4) Determining the propagation bins; and 5) Finding a timing values translation function.

  • Patent number: 6361786
    Abstract: A microbicidal organic polymer material for use in manufacturing of contact lenses, catheters, condoms, surgical sutures and gloves, medical examination devices and similar uses is provided by polymers to which is tightly adsorbed a disinfectant organic dye. Many polymers such as polyvinyl chloride and acrylic polymers show exceptional avidity for a number of microbicides, of acidic, basic, aromatic and/or hydrophobic character such as methylene blue and gentian violet. Consequently, devices constructed of these polymeric materials release no free dye to an aqueous solution. The material is generally a natural or synthetic polymer that releases no particles or fines into wounds or body orifices. Presence of adsorbed disinfectant organic dye allows the polymer to inhibit microbial growth in a number of different situations. Several common microbes are killed by being incubated in the present of an embodiment of the invention that contains a combination of methylene blue and gentian violet.

  • Patent number: 6351841
    Abstract: A method of creating multi-gate transistors with integrated circuit polygon compactors is disclosed. Specifically, in order to provide a more efficient layout when the size of a transistor is increased during design migration, a small multi-gate transistor is formed by inserting at least one parallel transistor over the diffusion layer of the target transistor, between a gate and contact. The compactor then enforces the new design rules, and adjusts the relative sizes of the parallel transistors as required. The resulting multi-gate transistor structure is much more compact than a single large transistor, providing a more efficient design layout.

  • Patent number: 6343225
    Abstract: The sensitivity of enzyme-based polarographic electrodes to oxygen concentration can be significantly reduced or eliminated by providing an oxygen-reservoir in intimate contact with the oxidative enzyme. This is achieved by making a stabilized emulsion between the enzyme and a compound in which oxygen is extremely soluble. An aqueous glucose oxidase solution is emulsified with a perfluorocarbon liquid, and the resulting emulsion is stabilized by chemically crosslinking the mixture to form a gel. Thin layers of the emulsion are fabricated by spreading a layer of the liquid emulsion before gelation occurs. Additional carrier proteins such as albumin may be added to the enzyne prior to crosslinking to protect enzymatic activity and enhance gel strength. Additional electron transport compounds may be added to further reduce sensitivity to oxygen concentration.
