Abstract: A monitoring cable includes an outer jacket having a generally rectangular cross-sectional profile. The monitoring cable further includes a strain monitoring unit disposed within the outer jacket, the strain monitoring unit including a plurality of optical fibers embedded in a potting layer. The monitoring cable further comprises a protective unit disposed within the outer jacket and spaced from the strain monitoring unit, the protective unit including an optical fiber disposed within a metal outer jacket. A method for monitoring a rail track includes attaching a monitoring cable to the rail track. The method further includes monitoring strain of the rail track by measuring movement of the optical fibers of the strain monitoring unit.

Abstract: A tactical deployable cable is provided. The cable includes a fiber optic unit. The fiber optic unit includes a plurality of optical fibers, each of the plurality of optical fibers having a maximum nominal outer diameter of less than or equal to about 250 microns. The fiber optic unit further includes a UV cured resin layer surrounding and encapsulating the plurality of optical fibers. The fiber optic unit further includes a thermoplastic elastomer buffer layer surrounding the UV cured resin layer. The cable may include a thermoplastic jacket surrounding the fiber optic unit, and a plurality of strength members disposed between the jacket and the fiber optic unit.

Abstract: A sensing cable is provided which includes exposed and/or unexposed optical fibers or wires disposed through the length of the sensing cable. The sensing cable includes a slotted core which is a one-piece integral member having a plurality of channels formed on a perimeter of the slotted core and which extend along a length of the slotted core. The sensing cable includes at least one exposed component which is disposed in a first channel of the plurality of channels and which extends along a length of the first channel. The sensing cable includes at least one unexposed component which is encased by a protective member, and the unexposed component and the protective member are disposed in a second channel of the plurality of channels. The unexposed component and the protective member extend along a length of the second channel.

Abstract: A cable including an outer metal tube and a first layer wire inside the outer metal tube, wherein the first layer wire has five inner elements surrounding a metallic center member and at least one of the inner elements is a metal tube containing an optical fiber.

Abstract: A cable including a core, a strength member surrounding the inner metal tube, and an outer layer surrounding the first layer, wherein the outer layer includes a polycarbonate material.

Abstract: Various instrumentation, implants and methodology are disclosed for implanting bone implants in the TLIF approach. The implants are preferably cortical bone of various shapes. The instruments include chisels, rasps, trials, inserters, spreaders, adjustors, curettes, rongeurs, and impactors. The instruments have straight and bent shafts. The implants may have recesses or notches in their sides for receipt of a mating insertion instrument. Some of the implants have a threaded hole for receiving a mating threaded stud of an implant insertion instrument. The implants may have saw tooth vertebral gripping surfaces which are lordotic or parallel, may be C-shaped, multi-faceted or annular.
