Abstract: Externally-initiated extension of a type that is managed by a runtime environment. As an example, third-party code that is not a runtime component may itself cause a type to be extended by causing a subject interface to be supplied to the type while also providing an implementation for that interface. The extension occurs by identifying a subject interface to supply to a type that is managed by the runtime environment, providing an implementation of the interface to the runtime environment, and instructing the runtime environment to supply the subject interface to the type using the implementation. The interface is thereafter available to computing entities that use the type.

Abstract: A medical device assembly including a catheter having a proximal end, a distal end, and a lumen therethrough. A medical device is disposed about a distal portion of the catheter. A removable loading tool and protector is disposed about the catheter and the medical device, and includes a body having a generally tubular configuration and having a proximal end, a distal end, an intermediate region disposed between the proximal end and the distal end, and a lumen disposed therethrough; and a proximal region having a length and extending from the proximal end of the body, the proximal region having at least one slit positioned adjacent to the proximal end of the body. The proximal region has a first inner diameter and the intermediate region has a second inner diameter, the first inner diameter of the proximal region being greater than the second inner diameter of the intermediate region.

Abstract: The present invention relates to methods and an apparatus for estimating a residual frequency error. According to an embodiment, an expected vector for selected subcarriers of a received symbol is estimated using a channel estimate vector and a reference vector; a sampling frequency mismatch is removed and a dot product is calculated using the expected and a received vector. An angle of the product is estimated and a change in angle from a previous symbol is calculated. The residual frequency is estimated using the calculated change in angle. In another embodiment, an expected subcarrier is estimated based on a channel estimate and on a reference subcarrier, an angle and magnitude of the multiplication between the expected and a received subcarrier are estimated; a phase offset is removed; a weighted mean value of the angles is calculated and the residual frequency error is estimated using a change in weighted mean angle.

Abstract: A clamp member for coupling a removable fluid conduit to a fluid conduit is disclosed. The removable fluid conduit may include a first interactive member for interaction with a second interactive member of the clamp member to couple the removable fluid component to the clamp member. The clamp member may include one or more gripping members to engage an exterior surface of the fluid conduit.

Abstract: A dry break coupling assembly for interconnecting components of a fluid handling system. The coupling assembly includes first and second valves, each includes a rotatable valve element for opening and closing a fluid passageway within a valve body. The over-center clamp mechanism is for interlocking the first and the second valves when the valves are in a connected arrangement, allowing the valves to be easily disconnected when the valves are in a closed position, having a pair of projecting bars disposed on an outer surface of a body of a first valve and a pair of clamp assemblies disposed on a body of the second valve. Each clamp assembly includes a clamp arm having a hook end for engaging one of the projecting bars, and a clamp lever for actuating the hook end to engage or disengage the projecting bar.
