  • Patent number: 11633226
    Abstract: Described herein are cannulas that comprise a cannula tube and a cannula tip. The cannula tube comprises a proximal end, a distal end, a cannula tube lumen, a sidewall, and a sidewall opening extending through the sidewall, the sidewall opening a proximal end and distal end. The cannula tip is secured to the distal end of the cannula tube and comprises a proximal tip portion that is inserted into the cannula tube lumen and a distal tip portion that extends beyond the distal end of the cannula tube. The cannula tip is configured to allow fluid to flow therethrough and is configured to eject a distal tip of an elongated device through the sidewall opening of the cannula tube as the elongated device is inserted through the cannula tube from the proximal end of the cannula tube.

  • Patent number: 8562935
    Abstract: The present invention is directed towards methods (processes) of providing large quantities of carbon nanotubes (CNTs) of defined diameter and chirality (i.e., precise populations). In such processes, CNT seeds of a pre-selected diameter and chirality are grown to many (e.g., hundreds) times their original length. This is optionally followed by cycling some of the newly grown material back as seed material for regrowth. Thus, the present invention provides for the large-scale production of precise populations of CNTs, the precise composition of such populations capable of being optimized for a particular application (e.g., hydrogen storage). The present invention is also directed to complexes of CNTs and transition metal catalyst precurors, such complexes typically being formed en route to forming CNT seeds.

  • Publication number: 20060056610
    Abstract: An advanced intelligent network (AIN) for providing the name and telephone number of a calling party to a called party comprising a plurality of central offices and a service control point (SCP). The central offices are equipped with AIN software which enables them to generate triggers which active queries requesting the name of the calling party. The SCP contains subscriber information which enables it to determine the type of query that is associated with each trigger. The SCP also incorporates a database containing telephone numbers and corresponding names. Software incorporated into the SCP enables it to respond to the queries sent to it by searching its database and returning the telephone number and corresponding name of a calling party to a called party's central office and the called party.

  • Patent number: 5869304
    Abstract: A method for specifying a fatty acid at the sn2 position of acylglycerol lipids including (a) transfecting a vector including the SLC1 gene or a variant thereof into embryonic biological material, and (b) allowing the SLC1 gene to specify the type of fatty acid at the sn2 position of acylglycerol lipids. Also provided for is an isolated SLC1 gene and a probe for its detection.

  • Patent number: 4985857
    Abstract: A general purpose expert system architecture for diagnosing faults in any one of a plurality of machines includes a machine information database containing information on characteristics of various components of the machines to be diagnosed and a sensory input database which contains vibration data taken at predetermined locations on each of the machines. The system knowledge base contains a plurality of general rules that are applicable to each of the plurality of machines. The generality of diagnosis is accomplished by focusing on components that make up the machine rather than individual machines as a whole. The system architecture also permits diagnosis of machines based on other parameters such as amperage, torques, displacement and its derivatives, forces, pressures and temperatures. The system includes an inference engine which links the rules in a backward chaining structure.
