摘要:
A repository contains multiple versions of an object but only a single version of the object is supplied when a query is made. The single version is automatically selected from among a number of versions that are otherwise returned in response to the query, based on a configuration associated with a workspace in which the query originates. The selected version of the object is then presented in a version resolved view, without exposing any information related to versioning of the object. Specifically, a number of configurations are established, each configuration containing no more than one version of each object in the repository. However, only one configuration is associated with each workspace from which a query can originate. The configuration that is associated with the workspace depends on whether the workspace is to be used for design of the repository or for use of the repository during live operation. Specifically, a single configuration (hereinafter “design time” configuration) is commonly associated with the workspaces of all developers. When the developers decide that a set of objects in the repository is ready for use in live operation, the set of objects is “deployed” by copying the design time configuration to generate a new configuration (hereinafter “run time” configuration) that contains the most current versions of all objects (as present in the design time configuration). Any number of run time configurations can co-exist with each other and with the design time configuration.

Disclosed herein are devices for altering gaseous flow within a lung to improve the expiration cycle of an individual, particularly individuals having chronic obstructive pulmonary disease (COPD). More particularly, a medical catheter is disclosed to detect the presence of blood vessels and to produce collateral openings or channels through the airway wall so that air is able to pass directly out of the lung tissue to facilitate both the exchange of oxygen ultimately into the blood and/or to decompress hyper-inflated lungs.

A communications system provides for secure communications of information over multiple communications links. The system includes a client device, a server device, and at least one, and typically multiple, available and usable communications channels, elements, modes and links for connecting the devices for communications of information therebetween. The system includes a link detector for determining existence and useability of the communications links for communications of the information, a pathfinder for selecting one or more of the communications links for communicatons of at least some of the information, a link handover for switching to the selected one or more communications links for communications of the information or portion thereof, and an auto reconnector for re-connecting to detected and selected one or more communications links for communications of the information or portions of it in the event that any communication is hindered, terminated or upset.

A method and apparatus for determining vulnerable plaque in a cardiovascular lumen is disclosed. In one embodiment, a guide member comprising a temperature sensor and a distance sensor are inserted into the cardiovascular lumen. The temperature of the cardiovascular wall is measured with the temperature sensor, and the distance from the temperature sensor to the cardiovascular wall is determined. The cardiovascular wall temperature is adjusted based on the distance determination, and the vulnerable plaque is determined based on the adjusted wall temperature measurement.

A preconnectorized outdoor cable streamlines the deployment of optical waveguides into the last mile of an optical network. The preconnectorized outdoor cable includes a cable and at least one plug connector. The plug connector is attached to a first end of the cable, thereby connectorizing at least one optical waveguide. The cable has at least one optical waveguide, at least one tensile element, and a cable jacket. Various cable designs such as figure-eight or flat cables may be used with the plug connector. In preferred embodiments, the plug connector includes a crimp assembly having a crimp housing and a crimp band. The crimp housing has two half-shells being held together by the crimp band for securing the at least one tensile element. When fully assembled, the crimp housing fits into a shroud of the preconnectorized cable. The shroud aides in mating the preconnectorized cable with a complimentary receptacle.

An adjustable bimini bracket is for use in connection with a boat having a railing tubular member on either side of the boat, and a bimini having strut tubular members. Left and right side plates are generally parallel and spaced apart. A transverse plate extends between the side plates. Ridges are disposed intermediate the transverse plate and the end. The side plates have a pair of collinear holes therethrough adjacent each end. The bimini bracket will slidingly engage the tubular member between the side plates. A bolt and a hand knob engage the first holes. The hand knob will be tightened, clamping the tubular member between the side plates, thereby preventing the bimini bracket from sliding on the tubular member. A second bolt and a nut engage the second holes for pivotal fastening of a strut tubular member to the bimini bracket, and for fastening a tie-down. The side plates taper upward in thickness from one end to the ridges. A plurality of ribs reinforces the side plates.

A safety cover 10 for automotive service pits 1 is constructed of square cross section hollow support members 11 welded to alternate links of double pitched roller chain segments 15. Cover 10 is divided into two halves wherein each half has support members 11 perpendicularly welded to two lengths of chain 15 at each end of support members 11. Support members 11 are further disposed in parallel spaced relation one to the other. Roller chain segments 15 are longitudinally supported at the top edges of the pit side walls 5 by opposing segments of C-channel 12. U-shaped bends 18 are provided in the lower lip 17 of opposing C-channel segments 12 and are disposed at, at least, one end which is adjacent an end wall 6 of automotive service pit 1. U-shaped bends 18 provide a receiving pocket for receiving the double pitched roller chain 15 and connecting support members 11 when cover 10 is slid into the open position.C-channel 12 and double pitched roller chain 15 are constructed of suitable materials such that the relative coefficient of friction between roller chain 15 and C-channel 12 inhibits sliding of the cover with the addition of any weight, e.g. a person standing on the cover.
摘要:
A bus structure for use in a computer network requiring high availability and reliability of communications. Multiple bus paths (2A, 2B) are provided. When a transmission is to be made, under most circumstances the path is selected at random, with all paths being equally probable. Thus, failure of a path is detected quickly. Each host device in the network connects to the bus paths through an interface, or port (1). The task of path selection is carried out by the ports, independently of the host devices. The ports also detect path failures and automatically switch over to an alternate good path upon detection of such a failure, all without host involvement. Virtual circuit communications between hosts are transparent to path selection and switching, so the only indication to a host device of a path failure is a decrease in throughput. Most of the signal processing apparatus of each port (10, 20A, 20B) is shared by the paths, only one path being supported at any given time. Thus, the addition of a second bus path involves only minimal cost.
