An apparatus and a method of detecting arc faults that have reduced susceptibility to nuisance tripping. The apparatus includes a current sensor, a differential current input sense circuit, a differential current (di/dt) characteristics sense circuit, an absolute current input sense circuit, an absolute current characteristics sense circuit, a power supply, a tripping circuit, a processing unit, and an electromechanical interface. The di/dt characteristics sense circuit provides information relating to the characteristic di/dt signature of a power line current. The absolute current characteristics sense circuit provides information relating to the absolute current waveform characteristics of the power line current. The processing unit correlates the di/dt characteristics to the absolute current characteristics to distinguish between electrical arc faults and nuisance loads, thereby reducing the susceptibility of the apparatus to nuisance tripping.

A rotating surgical stapler having a proximal end and a distal end includes a handle at the proximal end and an end effector at the distal end for selective rotation to improve access to tissue requiring treatment and ease of use of the present linear surgical stapler. A support shaft connects the handle to the end effector and includes a longitudinal axis. The end effector is coupled to the support shaft for rotation about a longitudinal axis of the stapler.

A magnetic head including an electrical lead layer that is comprised of a material having an ordered-phase crystalline structure. In a preferred embodiment, the ordered-phase crystalline structure of the electrical lead is epitaxially matched to the crystalline structure of the hard bias layer upon which it is formed, and there is no need for a seed layer for the electrical leads. Electrical leads comprised of the materials used in the invention having an ordered-phase crystalline structure, particularly a B2, L10, L11, and L12 structure, will have significantly reduced resistivity over the prior art electrical leads that are typically composed of rhodium or tantalum. As a result, thinner electrical leads can be fabricated which carry the same, or even greater, current than the prior art rhodium or tantalum leads. The preferred leads are comprised of NiAl, FeCo, or CuZn having a B2 crystalline structure, and alternative embodiments are comprised of CuAu, Cu3Au, CuPt, and Cu3Pt.

The present invention provides a binding domain of the protein Siah, which is known to be an important protein in the ubiquination pathway. The domain is capable of binding substances, co-factors and interactors of the Siah protein. The invention also provides a zinc-binding and a dimerisation domain of Siah. Also provided are methods of screening compounds that are capable of interacting with the binding domain, as well as methods of treating diseases including cancer, infertility, and inflammation.
摘要:
A stacking apparatus and a method for assembly of electrochemical cells. The stacking apparatus includes at least one stacking head having an adjustable holding member adapted to hold an electrochemical laminate of a pre-determined length and means for adjusting the shape of the electrochemical laminate of the pre-determined length during stacking of a plurality of electrochemical laminates. The electrochemical laminates are assembled in a way that prevents air entrapment between the electrochemical laminates.

A fresenel zoned microstructured optical fibre is described. The fibre is constructed of concentric zones, each zone being defined by discontinuities in the refractive index. The refractive index within each zone may either be constant or may vary, for example each zone being a section of a parabola or hyperbola. The fibre may be used as a lens, for example for coupling light between fibres with different core sizes.
