  • Publication number: 20020087537
    Abstract: Methods and apparatus for parallel searching through a data stream. Using a register bank and comparators, the device performs a brute force search through a data stream to quickly find one or more patterns therein. The invention sacrifices physical space for speed by using multiple comparators on the same register bank. The output of the comparators is fed into a decoding circuit which determines the locations of matches and mismatches. Matches are compared against a database/table to determine their significance.

  • Publication number: 20020078076
    Abstract: Information is transferred between a server system and a client system. Network data that includes a portion having state information is received from the server system. The portion is removed from the network data, and state information is appended to at least one address that corresponds to a link located in a remaining portion of the network data. The remaining portion of the network data is transmitted to the client system. Thereafter, a request is received from the client system and includes an address. A portion having state information is removed from the address, and the state information is formatted. A remaining portion of the address and the formatted state information are transmitted to the server system.

  • Patent number: 6398782
    Abstract: The method, device and system for electrical sealing of a puncture opening in a blood vessel wall. In a first embodiment, a vascular sealing probe has two bipolar electrodes formed thereon, is insertable to a position whereat the bipolar tip is adjacent the blood vessel puncture site to effect electrocauterization or electrocoagulation of the puncture site. In a second embodiment the bipolar vascular sealing probe has a first electrode formed thereon and an electrode-guide wire has the second bipolar electrode formed thereon. The electrode-guide wire is passable through a lumen formed in the probe such that the second electrode on the electrode-guide wire is positioned close enough to the first electrode positioned on the probe to permit electrical current to pass therebetween.

  • Patent number: 6224561
    Abstract: A one-handed blood sampling reservoir for an infusion line having a configuration which allows discard fluid to be drawn into the reservoir and then returned to the patient in two squeezing motions. Both drawing and returning steps are performed by squeezing two of a plurality of finger grips provided on the reservoir. The reservoir may include a bracket which enables one-handed operation in either a hand-held or a pole-mounted configurations. In the alternative, the reservoir and finger grips may be formed by telescoped inner and outer housings without a bracket. The reservoir desirably includes a syringe-like body forming a chamber and a plunger/piston assembly reciprocal therein to vary the volume of the chamber. A narrow gap is provided in the chamber open to both inlet and outlet ports when the piston is fully seated to ensure a consistent and minimum flush volume in the chamber.

  • Patent number: 5948815
    Abstract: The invention provides methods and compositions for reducing microbial cytotoxicity to a cell, by contacting a cell subject to extracellular microbial cytotoxicity with an effective amount of at least one of genistein or a genistein derivative. In preferred embodiments, the microbe is a gram-negative bacterium, a non-Enterobacteriaceae or a Pseudomonas aeruginosa or cepacia and the host cell is a mammalian epithelial cell, especially a lung epithelial cell or a corneal epithelial cell. The genistein or genistein derivative may be administered prophylactically prior to infection, subsequent thereto and/or in conjunction with conventional antibiotic therapies.

  • Patent number: 5803770
    Abstract: A female electrical connector (164') is carried on an electrical cable (24') including plural electrical conductors (28'). The female connector includes an insulative housing (34a', 34b') defining a blind cavity (36') therewithin and an axial opening outwardly from the cavity. The housing carries a printed circuit board (166) carrying plural wire-like contacts (40') which individually connect with the conductors of the electrical cable. The wire-like contacts extend into the cavity of the connector for deflecting in spring-like contact with electrical contacts (60) carried by a male connector (20) when the latter is inserted into the cavity of the female connector. A comb feature (50') of the female connector is formed by a strong end wall (138') of the blind cavity and in a respective one of plural slots (48') of the comb feature movably receives a free end portion (46') of each one of the plural wire-like contacts.

  • Patent number: 5611255
    Abstract: A cutter assembly for food film includes a rigid planar base with a movable metal strip anvil movably positioned thereon. A slidable cutter arm for forward or rearward movement is attached to a rear axle affixed to the base. The assembly, in one embodiment, can be positioned atop a conventional box of rolled food film. Safe, manual cutting of the food film to convenient lengths can be easily accomplished with minimal training and effort. A turret blade allows for convenient blade changing when dulling occurs.

  • Patent number: 5354272
    Abstract: An improved integral flow-through injectate delivery system comprises fluid flow means having a proximal and a distal end. The proximal end comprises a first port having fluid inlet means for connecting the flow means to a source of fluid injectate and a second port adapted to be connected to a syringe means. The distal end of the fluid flow means is adapted to be connected to a fluid delivery means for delivering the injectate to the patient and the syringe means is adapted to direct injectate fluid from the injectate source through the fluid inlet and the fluid flow means to the fluid delivery means. A first check valve is in fluid-flow communication with the fluid inlet means and the fluid flow means and a second check valve means is in fluid-flow communication with the fluid flow means and the fluid delivery means. A sensing means is disposed within the fluid flow means at its distal end for sensing a characteristic of fluid flowing therethrough, usually temperature.

  • Patent number: 5291896
    Abstract: A cardiac output probe assembly is disclosed wherein the assembly includes a chest tube which carries a cardiac output probe therein. The chest tube includes a main lumen for draining fluids from the thoracic cavity of the chest and a secondary lumen which carries leads attached to the probe. The probe is attached to the pulmonary artery or aorta vessel with detachable tines and/or sutures. The tines are uniquely configured to ensure that good contact between the probe and vessel is maintained. When cardiac output monitoring is complete, a pulling force is applied to the probe leads extending out through a proximal end of the tube. The pulling force detaches the tines and sutures, releasing the probe from connection with the vessel. Further withdrawal of the leads through the tube retracts the probe within the tube, where it is housed until the tube is removed from the thoracic cavity.

  • Patent number: 4770415
    Abstract: An electronic game simulates a shove-a-coin game by causing successive illumination of lights on a display, which simulates movement of a coin, in response to the activation of a control button. The final position of the "coin" relative to a scale is determined by the speed, or total distance of movement, of the button, and that final position determines the result of the game, which may be indicated by suitable indicators adjacent the scale. The control of the movement of the "coin" is such that, for speeds or distances of movement of the button less than a first value, the "coin" does not move, whereas for speeds or distances of movement of the button greater than a second value, the "coin" moves to an end position, corresponding to a losing result. Thus the skill of the game is to activate the button by the right amount to cause the "coin" to move to a winning position at some intermediate point along the scale.

  • Patent number: 4750179
    Abstract: Bipolar violation error counters are rendered insensitive to bipolar violations arising from the presence of bipolar eight-zero suppression (B8ZS) patterns in a bipolar pulse train by detecting B8ZS patterns in the pulse train applied to the error counter, and zeroing those bits of the B8ZS pattern which produce bipolar violations.
