Abstract:
The present invention relates to nanofibrous coatings on medical devices such a surgical mesh or stent, wherein the coating is mechanically attached to the device. The principal mechanism for attaching the coating is through causing the fibers to permeate and entangle with the substrate.
Abstract:
A medical needle shield apparatus is provided that includes a needle hub (104 ) having an outer needle cannula (103) extending therefrom. An inner needle (106) is disposed for slidable movement with the outer needle cannula (103). At least one shield (101) is extensible from a retracted position to an extended position to enclose a distal end of the inner needle (101). The shield (101) includes a binding member (105) disposed within the shield (101) and defines binding surfaces (122) that form an aperture (138) configured for slidable receipt of the inner needle (106). The binding member (105) includes a binding member reset surface (107) aligned with a reset surface (108) for engagement therewith to allow reuse of a shielded needle apparatus.
Abstract:
The present invention relates to methods and apparatus for removing water and/or water-based compounds from organic liquids/fluids. In one embodiment, the present invention relates to methods and apparatus that utilize fibrous media that contains, is impregnated, or is formed from at least one super absorbent compound, where the fibrous media is formed from nanofibers.
Abstract:
A blind rivet includes a hollow rivet body having a longitudinally extending indented groove. The groove may be shaped to impart rivet setting characteristics that may be varied to provide desirable fastening characteristics for joints in a number of industries. The shape of the indentation on the rivet body may be varied to cause a portion of the rivet body to collapse and form a secondary head at a predetermined longitudinal location.
Abstract:
A system for delivering a desired mass of gas, including a chamber, a first valve controlling flow into the chamber, a second valve controlling flow out of the chamber, a pressure transducer connected to the chamber, an input device for providing a desired mass to be delivered, and a controller connected to the valves, the pressure transducer and the input device. The controller is programmed to receive the desired mass from the input device, close the second valve and open the first valve, receive chamber pressure measurements from the pressure transducer, and close the inlet valve when pressure within the chamber reaches a predetermined level. The controller is then programmed to wait a predetermined waiting period to allow the gas inside the chamber to approach a state of equilibrium, then open the outlet valve at time=t0, and close the outlet valve at time=t* when the mass of gas discharged equals the desired mass.

Abstract:
A vaporizer including an inlet for liquid and an outlet for gas, a gas valve controlling gas flow to the outlet of the vaporizer, and means for heating liquid flowing between the liquid inlet and the gas valve. The vaporizer also includes means for increasing a heat transfer rate of the liquid flowing between the liquid inlet and the gas valve, and for causing a pressure drop in the liquid so that a pressure of the liquid drops below a vapor transition pressure of the liquid upon reaching the gas valve. The pressure drop occurs under isothermal conditions, and the liquid is vaporized on demand only when the valve is opened. The means for increasing a heat transfer rate and for causing a pressure drop can be a plug of porous media.

Abstract:
A vehicle entertainment and accessory control system (10) is disclosed. The control system (10) provides a plurality of touchscreens (12,14,16) that present user interfaces (38,62) concurrently with video windows (40,64). The user interfaces (38,62) enable users to control various entertainment components, such as a video display (22) and a speaker (24), as well as other vehicle accessories, such as an intercom (28). The entertainment components are controlled via a universal infrared controller (20). A master touchscreen (12) enables a user to control access to the system (10) via a plurality of passenger touchscreens (14,16) by disabling or limiting the use of the passenger touchscreens (14,16).
Abstract:
A thin ribbon spirally wound polymer conduit and method of forming, wherein a helical reinforcing bead is interposed adjacent overlapping layers of ribbon. Further, a method of continuously forming spirally wound conduit wherein a sacrificial layer, preferably having a different base polymer to that of the conduit, is first applied to the former before the conduit is formed overtop.
