摘要:
A delivery wire assembly for delivery of an occlusive device to a location in a patient's vasculature, the assembly having a distal end portion comprising a proximal rigid segment, a distal rigid segment, and a flexible segment disposed between the proximal and distal rigid segments. The assembly also has a delivery wire conduit having a proximal tubular portion coupled to a distal coil portion, the respective tubular and coil portions defining a conduit lumen. A plug is seated in the conduit lumen and secured to an interior surface of the delivery wire conduit. A core wire is disposed in the conduit lumen and having a distal end extending through the plug, so that the plug secures the core wire to the delivery wire conduit. The plug may form a substantially fluid tight seal of the conduit lumen.
摘要:
A core wire of a delivery wire assembly for delivery of an occlusive device to a location in a patient's vasculature, includes a wire having a polyimide coating, with a polymer jacket disposed around the polyimide coating, and a hypotube disposed around the polymer jacket. The delivery wire assembly further comprises a delivery wire conduit including a coil disposed around the wire, wherein a proximal end of the coil is connected to a distal end of the hypotube. The polyimide coating may be enhanced with a nano-particle or micro-fiber ceramic, such as yttria-stabilized zirconia.
摘要:
A stabilising and release system, for an agricultural apparatus having a mounting portion for mounting the apparatus to a tractor, a pendulum mounted on the mounting portion, and a boom for spraying or cutting, which is pivotally mounted to the pendulum at a pivot point so as to allow pivoting of the boom relative to the pendulum. The system stabilises the boom against movement imparted to it by disruptive forces which disturb the natural position of the boom by proving a rigid damper arranged between the support frame and the boom and arranged to damp relative movement of the boom and the mounting frame caused by disruptive forces, the damper has an articulated coupling which allows the damper to articulate so that the damper can follow the motion of the boom thus damping any undesired swaying action caused by bumps and ruts over which the tractor passes.

This description relates to methods and systems for providing a connection from a first system to a second system using a server. In one embodiment, a method includes receiving a user input to establish a sharing service on a first data processing system (DPS) for a user of a second DPS; determining, in response to the user input, whether the user of the second DPS has an account with a service which includes a server which is capable of being coupled to the first DPS through a network; receiving from the server, if the account exists, authentication data for use in authenticating the user of the second DPS when the sharing service is enabled. Other methods and systems and computer readable media are described.
摘要:
A method of forming a low-defect, substantially relaxed SiGe-on-insulator substrate material is provided. The method includes first forming a Ge-containing layer on a surface of a first single crystal Si layer which is present atop a barrier layer that is resistant to Ge diffusion. A heating step is then performed at a temperature that approaches the melting point of the final SiGe alloy and retards the formation of stacking fault defects while retaining Ge. The heating step permits interdiffusion of Ge throughout the first single crystal Si layer and the Ge-containing layer thereby forming a substantially relaxed, single crystal SiGe layer atop the barrier layer. Moreover, because the heating step is carried out at a temperature that approaches the melting point of the final SiGe alloy, defects that persist in the single crystal SiGe layer as a result of relaxation are efficiently annihilated therefrom. In one embodiment, the heating step includes an oxidation process that is performed at a temperature from about 1230° to about 1320° C. for a time period of less than about 2 hours. This embodiment provides SGOI substrate that have minimal surface pitting and reduced crosshatching.

Method and system for transmitting data using power lines are disclosed. The method includes tying low voltage lines for the transmission of BPL signals but maintaining isolation of those voltage circuits in accordance with normal power distribution system practices. The system includes a plurality of power transformers, one or more low voltage circuits, wherein the low voltage circuits operate as separate electrical circuits, and a low voltage signal coupler, operable to couple one or more of the low voltage circuits.
摘要:
An agricultural apparatus is disclosed. The apparatus is adapted to be mounted to an agricultural machine such as a tractor and is provided with a boom having two arms extending in a direction substantially transverse to the agricultural machine. The boom arm are provided with a plurality of heads, adapted for either cutting or spraying, and can be used to cut or spray discrete areas of vegetation over which the apparatus passes. The apparatus is adapted to maintain the arms in a direction substantially parallel to the vegetation over which it is passing irrespective of the terrain.

Disclosed is a security device to protect the spare tire on a vehicle from possible theft. The spare tire, especially in sport utility vehicles, is located on the rear underside of the vehicle and is secured by a cable and yoke. The security device comprises a plate or disk which is attached to the spare tire rim and prevents unauthorized access to cable and yoke, thereby minimizing the possibility of theft.
