A method of endovenous laser treatment in disclosed. An introducer sheath 40 is introduced into a vein and an optical fiber 12 is introduced through the introducer sheath until a first marking 45 on the optical fiber 12 indicates that the distal end of the optical fiber 12 is substantially in alignment with the distal end of the introducer sheath 40. The introducer sheath 40 is then withdrawn relative to the optical fiber 12 until a second marking 46 on the optical fiber 12 indicates that the distal end of the optical fiber 12 extends a predetermined distance beyond the distal end of said introducer sheath 40. Laser radiation is passed down the optical fiber 12 so that laser radiation is delivered to the inner wall of the vein and the introducer sheath 40 together with the optical fiber 12 are withdrawn a certain distance along the vein.

The invention relates to a screw fastener comprising a threaded shank having a force application means for torque transmission and a screw fastener point. The threaded shank consists of a shank core and a self-tapping thread, and the thread is designed as a prominence which runs helically over the shank core, is defined by two flanks meeting in an outer thread edge and has a radial height (H). The outer thread edge, at least in a section of the thread, runs in a wavelike manner in the radial direction with an amplitude between wave crests having the height (H) and wave troughs having a height (h) reduced by the amplitude. The thread, at least in the region of one of its flanks, has niches in the region of the wave troughs of the thread edge, which niches interrupt the surface of the flank and their outer boundary is the thread edge, the thread in each case having a certain first apex angle (α), formed between the flanks, in those regions of the wave crests of the thread edge which are not interrupted by niches and a second apex angle (α′) in the deepest regions of the wave troughs of the thread edge. The first apex angle (α) between the flanks is approximately within the range of 30° to 35°, the second apex angle (α′) being 30° up to at most 58°.

A write barrier is implemented using thread-local hash table based write barrier buffers. The write barrier, executed by mutator threads, stores addresses of written memory locations or objects in the thread-local hash tables, and during garbage collection, an explicit or implicit union of the addresses in each hash table is used in a manner that is tolerant to an address appearing in more than one hash table.

The fiber filling is loaded with single or multiple antigens, and optionally one or more biologically active compounds such as cytokines (e.g. lymphokines, chemokines etc.), attachment factors, genes, peptides, proteins, nucleotides, carbohydrates or cells depending on the application.

The invention discloses a visual-content-based method for establishing a multi-level semantic map. The visual-content-based method comprises the following steps: gathering images shot by a robot wandering in an environment and labeling the scenes of spots for photography; constructing a hierarchical vocabulary tree; constructing a knowledge topological layer so as to grant knowledge to the knowledge topological layer; constructing a scene topological layer; constructing a spot topological layer. According to the visual-content-based method, a visual sensor is utilized for constructing the multi-level semantic map for a space, and digraph structure is used on the knowledge topological layer for storing and inquiring the knowledge, so that unnecessary operation can be eliminated in a knowledge expression system, and the inserting and inquiring speed is quick; the scene topological layer is utilized for carrying out abstract division on the environment so as to abstractly divide the whole environment into subdomains, so that the image searching space and the path searching space can be reduced; the spot topological layer is utilized for storing specific spot images, the self-positioning can be realized by adopting image searching technology, and the error accumulation problem of self-positioning estimation is solved without maintaining the global world coordinate system.

The present invention relates to various embodiments of an improved high-speed corner flange connection member which is specifically shaped and designed to increase the clamping force applied to adjacent duct flanges when adjacent duct sections are connected together. In some embodiments, the corner connection members include creases or bends which allows the leg portions to be bent or angularly deflected away from such creases downwardly so as to form a bowed configuration; some embodiments include clearance holes and tap holes which are strategically positioned on the corner element such that when a pair of duct sections are positioned in end-to-end relationship for joinder, the opposed corner elements are arranged such that a clearance hole is positioned in registration with a tap hole; other embodiments include similarly shaped openings which are associated with the respective opposed corner elements; and in still other embodiments a substantially flat corner element is constructed utilizing the strategically placed clearance and tap holes so as to achieve a faster and stronger connection including the use of standard carriage type bolts. Still further, the present invention includes the use of a plurality of differently configured high-speed fastener members which are specifically designed to substantially eliminate misalignment and cross-threading issues commonly associated when using the conventional bolt / washer / nut arrangement for fastening adjacent duct sections.

There is provided an injection device comprising a barrel adapted for receiving a syringe assembly, a trigger assembly, tension spring means and stopping means. The trigger assembly comprises retractable blocking means for blocking the syringe assembly at a first axial point within the barrel and a trigger for retracting said blocking means from blocking the syringe along said first axial point along the barrel. The tension spring means has a barrel end mountable on the barrel and a syringe end mountable on the syringe assembly, whereby said tension spring means imparts an axial force to the syringe assembly when the syringe assembly is in a cocked position. The stopping means are for retaining the syringe assembly in an injected position within the barrel upon release of the syringe assembly from the cocked position followed by axial travel of the syringe assembly within the barrel under the influence of the axial force.

A ratcheting take-up device that compensates for imperfect alignment in a tie rod continuity system in the frame of a building wall. The upper ends of the tie rods are tightly clamped within the take-up device by domed segments inserted in a bowl-shaped housing. The segments are also forced together by a compression member in the housing. The domed shape of the segments and the bowl shape of the housing cooperate so that the segments can rotate in any direction to accommodate tie rods that are not perfectly vertical, without a corresponding loss of strength in the connection.
