  • Patent number: 6446871
    Abstract: An interactive data transfer system and method is provided. In embodiments of the invention, the data transfer system includes a computing device, and a data well for interfacing with an elongate instrument, the elongate instrument having a data transfer end with a data transfer tip. The data well has a housing with an opening for receiving the data transfer tip of the elongate instrument. The data well also has a communications port operatively coupled to the computing device to provide data to the computing device, and the data well has a data communication device contained in the housing for interfacing with the data transfer tip when the data transfer end of the elongate instrument is received in the opening The computing device is programmed to receive data from the data well. The received data includes data indicative of at least one address on a global communications network.

  • Publication number: 20020103315
    Abstract: A catalyst composition for the polymerization of olefins is provided. The catalyst composition comprises a monocycloalkadienyl/metal/ligand catalyst precursor, wherein at least one ligand is capable of multihapto attachment to the metal atom through a carbon or hydrogen atom, and a cocatalyst capable of irreversibly abstracting a ligand from the catalyst precursor.

  • Patent number: 6346584
    Abstract: The present invention relates to the use of at least one acid and at least one base and/or at least one reductant and at least one oxidant that when used with a polymerization catalyst in a polymerization process results in the controllable generation of a catalyst inhibitor that renders the polymerization catalyst substantially or completely inactive.

  • Patent number: 5865800
    Abstract: For achieving, e.g., an improved electrophysiology catheter for examination of the heart, or a catheter accessing the brain, the invention, in one aspect, features an elongated wound wire coil extending through the hollow catheter body of a steerable catheter. The coil is constructed and arranged to enable the catheter body to withstand reactive compressive load without distortion during application of tension on the pull wire and to transmit torque from the proximal to the distal tip portion of the catheter to enhance fidelity of rotational positioning of the distal tip in response to rotational orientation of the proximal portion of the catheter. The coil is shown in frictional torque-transmitting relationship with the interior of the hollow shaft substantially along the common length of the catheter body when the catheter is bent. Steerable catheters with augmented throw for one-handed operation and important improvements in construction features are also shown.
