A pipe coupling 1 for connecting together two pipes in a fluid-tight manner comprising an outer tubular casing 10, an inner tubular casing 20 and a tubular sealing sleeve 30. The sealing sleeve 30 has two sets of inwardly projecting ribs 32, which in use, are pressed into sealing engagement with the respective ends of the pipes. The inner and outer casings are longitudinally split and tensioning screws 17 on the outer casing can be tightened to tighten the outer casing around the inner casing and the sealing sleeve. Frusto-conical gripping rings 40 grip the pipes by engaging radial abutment surfaces facing away from the pipe ends and positioned close to the ends of said pipes in order to secure the pipes against axial displacement.

An attachment connector for powered equipment such as a tractor or implement comprises a bearing (11) adapted to be locatable about a PTO output/input stub. The attachment connector may have a base plate portion (10) with a bearing (11) located therein which has a central aperture sized to be closely locatable about a PTO output/input stub of a tractor or implement, the base plate (10) also carrying a tubular portion (12) extending from one face thereof and formed to provide one part of a connector mateable (13) with a further part carried on an attachment, structure being (14) provided to prevent rotation of the base plate (10) and tubular portion (12) with rotation of the PTO output/input stub.

A lancet assembly includes a reusable base unit that defines a handle for a lancet assembly and houses a biasing mechanism for driving a lancet into the finger of a user. The base unit includes a spring biased hammer that once cocked, can be released to drive a lancet. A lancet is included in a disposable end cap that may be releasible attached to one end of the base unit. The end cap includes integral resilience spring fingers that maintain the lancet completely within the end cap before and after use, and functions to return the lancet after engagement of the lancet and hammer. The end cap can be rotated to orient the end cap relative to user's finger to control the depth of penetration of the lancet into the user's finger.

A device for applying a plurality of hemoclips to blood vessels and the like includes a longitudinally disposed frame having a pistol grip and an opposed trigger lever extending from the proximal end thereof. A narrow, internal passageway extends the length of the frame, from a loading opening at the proximal end to a fixed lower jaw at the distal end of the frame. A plurality of U-shaped hemoclips is disposed in the passageway with the points thereof extending toward the distal jaw portion. An upper jaw extends from a clevis member which straddles the frame and is pivotally joined to an upper medial portion thereof. The trigger lever is pivotable to cause the clevis member to pivot upwardly and the upper jaw to close upon the lower jaw to crush a hemoclip disposed therebetween. A piston resiliently biased in the internal passageway urges the hemoclips toward the jaw portion, and a feed release lever is disposed at the proximal end of the passageway to discharge a hemoclip from the passageway to the jaw portion with each full actuation of the upper jaw.

A disclosed example method to identify a failure in a logical circuit involves receiving non-requested trap data from a plurality of switches forming a logical circuit. The logical circuit spans first, second, and third logical networks. The example method also involves polling first and second switches of the logical circuit exclusive of others of the plurality of switches of the logical circuit. The first switch forms a first network-to-network interface between the first logical network and the second logical network. The second switch forms a second network-to-network interface between the second logical network and the third logical network. The first and second switches are selected for polling based on the trap data indicating a problem at the first and second switches. The example method also involves identifying a failure of the logical circuit without manual intervention based on the polling.

Methods and systems are provided to automatically reroute logical circuit data. In accordance with an example method, a failure of a dedicated logical circuit in a packet-based network is identified. The dedicated logical circuit has a first logical circuit identifier assigned prior to identifying the failure. The dedicated logical circuit connects a host device to a remote device to communicate data that originates and terminates only at the host device and the remote device. A logical failover circuit comprising an alternate communication path for communicating the data is selected. When the first logical circuit identifier of the dedicated logical circuit does not match a second logical circuit identifier of the logical failover circuit, the second logical circuit identifier is renamed to match the first logical circuit identifier. The data is rerouted to the logical failover circuit without manual intervention.

Methods and systems are provided for automatically rerouting data. In accordance with a disclosed example method, congestion is identified in a logical circuit. The logical circuit comprises at least a first communication path in a first local access and transport area, a second communication path in an inter-exchange carrier, and a third communication path in a second local access and transport area. The example method also involves determining that the congestion is isolated to the second communication path in the inter-exchange carrier. Data associated with the logical circuit is rerouted without manual intervention using an alternate communication path to bypass the inter-exchange carrier. The rerouting comprises routing the data through the first local access and transport area, the alternate communication path, and the second local access and transport area.
摘要:
A method and system are provided for automatically rerouting logical circuit data in a data network. A failure is identified in a logical circuit in a data network. The logical circuit may include a communication path for communicating data. Once the failure in the logical circuit is determined, a logical failover circuit is then identified. The logical failover circuit includes an alternate communication path for communicating the data for the failed logical circuit. After the logical failover circuit has been identified, the data from the failed logical circuit is rerouted to the logical failover circuit without manual intervention. After the data has been rerouted the logical failover circuit, a determination is made as to whether the failure in the logical circuit has been corrected. If it is determined that the failure in the logical circuit has been corrected, then the data from the logical failover circuit is rerouted back to the logical circuit in the data network without manual intervention.
摘要:
A disclosed example method involves identifying a first logical circuit identifier for a first logical circuit in a first network. When a failure is detected in the first logical circuit, a second logical circuit identifier for a second logical circuit in a failover network separate from the first network is identified and the first logical circuit is renamed without manual intervention to identify the first logical circuit using the second logical circuit identifier. The second logical circuit is to reroute data from the first logical circuit.

The present invention concerns a method of detecting information relevant to the characterization of joint movements, wherein markers fitted on both sides of a body joint are used for the analysis of joint movements and wherein the method includes: determining a mean marker configuration and determining time-dependent discrepancies from the mean configuration, wherein an orthogonal distance regression is carried out for determining a mean marker configuration and wherein markers fitted on a respective side of the body joint are used; carrying out a weighted orthogonal distance regression using the time-dependent discrepancies from the mean configuration for weighting, wherein markers fitted on a respective side of the body joint are used; and solving a linear equalization problem using items of information which were determined by carrying out the weighted orthogonal distance regression.
