	Carpeteria Delta Co. - STAINMASTER® Tactesse® Carpet
		The unique touch of Tactesse® fiber is achieved by using finer filaments, which yeilds a lower denier per filament (dpf).
		The filaments of Tactesse® fiber are approximately 12 dpf, providing the optimum balance between floor performance and general aesthetics.
		Carpets made from Tactesse® fiber stand up against traffic and wear because the individual fiber cross-section has been altered to obtain a tighter, more densely packed fiber bundle with fewer air pockets.

		Reported in both 100ths and 32nds, fiber length, or staple, is the average length of the longer one-half of the fibers in a "beard" of parallel fibers passed through a sensing point.
		Fiber strength is determined by the force in grams to break a fiber bundle one tex unit in size.
		Fiber maturity, on the other hand, is a major determinant of dye absorbency and retention, both of which improve proportionate to greater maturity.

		The fornix fibers are fused into one thick bundle on the midline behind the septum, but separate laterally into two branches (one on each side of the brain) as they descend to the base of the brain.
		Begin at the frontal pole and cut sections perpendicular to the dorsal surface of the brain until the anterior horn of the lateral ventricle is visible, then keep cutting sections about 1 cm thick until you have passed the posterior horn of the lateral ventricle.
		Fibers that connect one area of cortex with another area of cortex in the same hemisphere are called association fibers.

		Three major types are: (a) mode dispersion caused by differential optical path lengths in a multimode fiber; (b) material dispersion caused by a differential delay of various wavelengths of light in a waveguide material; and (c) waveguide dispersion caused by light traveling in both the core and cladding materials in singlemode fibers.
		In a fiber interconnection, that portion of loss that is not intrinsic to the fiber but is related to imperfect joining, which may be caused by the connector or splice.
		Fiber design in which the refractive index of the core is lower toward the outside of the fiber core and increases toward the center of the core; thus it bends the rays inward and allows them to travel faster in the lower index of refraction region.

	Fiber Optic Bundles (Site not responding. Last check: 2007-10-27)
		Fiber optic bundles are groups of fibers bound together, typically at the ends only, and encased in a flexible protective jacket.
		By leaving the center section of the fiber unbound by epoxy and free to move inside of the protective jacket, the bundle maintains a minimum bend radius close to that of the individual fibers making it up.
		The percentage of useable area in a bundle is the total fiber core area divided by the area of the end face exposed to the source.

	Polymicro Technologies > Catalog > Bundles and High Fiber Count Assemblies
		A fiber optical bundle is a cluster of optical fibers with some geometric arrangement at each end to accomplish the transport of light from one place to another (or several others), usually along a non-linear path.
		The fiber could be arranged in a circle at one end and a ring at the other to make a ring light, which is now quite commonly used on microscopes.
		Jacketing materials, to protect the fiber bundle from damage, may also put some limitations on the type of environment in which the assembly can be used.

	Fiber Optic Lighting Dries Out
		This fiber optic cable, or tube, employs a lighting characteristic called total internal reflection to carry the light throughout the length of the cable.
		The light entering the fiber optic tube is trapped within the core and is continually reflected as it moves down the path.
		Consider also that the optical fiber is specified on the basis of the beam spread and focus of the lamp, the “angle of acceptance” of the fiber, the location of the fiber relative to the light source, and how the fiber is bundled.

	High-Temperature Fiber Optic Imaging
		A fiber grown from an approximately 1-mm-diameter source rod can be used as the source material for a second step with a diameter reduction that results in 100μm- to 150μm-diameter fibers as long as 3 m.
		Since the focal length of the lens was 5 mm, a displacement of the fiber bundle end of 10 mm from the center of the lens (2-mm thick) and a placement of the target also 10 mm from the lens center would result in a 1:1 magnification image of the target onto the fiber bundle.
		Although the shortness of the sapphire fibers might be expected to cause too much heat transfer to the camera, metal shields and air fans permitted essentially room-temperature operation within a few centimeters of the outside of the furnace, whereas the fiber bundle protruded 13 cm from the furnace.

		Typically, fiber core might have an index (nf) of 1.62, and the cladding an index (nc) of 1.52, although a range of indexes is available.
		Fused silica bundles are made of fibers with relatively large (250 mm) cores; for example, the cladding on such a bundle can be only ~9-10 mm thick.; Bundles may have from 50-500 fibers.
		The transmittance is derived by ratioing the radiation through the fiber bundle to that through an aperture of the same size.

	Class Definition for Class 19 - TEXTILES: FIBER PREPARATION
		Such weakening is resorted to mainly for the purpose of minimizing the requisite magnitude of the breaking forces and the consequent loss of fiber extensibility, and for the purpose of predetermining the points along their length at which certain filaments will be broken.
		Processes and apparatus in which a bundle or web of filaments travelling in a plane parallel to the axis of a rotating cutter comes into contact with the cutter at a translational speed differing from the peripheral speed of such cutter.
		The fiber is caught and drawn along between two surfaces in rolling contact, the angle of contact being such that the seed will not enter, but will be held back and detached.

	BRAINSTEM NUCLEI
		The purpose of this section is to lay down a conceptual framework of the cranial nerves.
		The fibers of the facial nerve do not acquire their myelin (and become dark) until they arrive at the hairpin turn, so you cannot even trace them back to the nucleus.
		fibers, from the taste buds, are predominantly (from the front 2/3 of the tongue, anyway) carried by the facial nerve.

	Introduction/Background
		The fornix is a bundle of fibers that parallels the corpus callosum through much of its course.
		The more rostral part of the structure is made up of fibers largely originating in the hippocampi, paralleling the midline, and these are called the body of the fornix.
		Just dorsal to the anterior commissure, the fibers of the body of the fornix separate into two distinct bundles of fibers which move just lateral to the midline, forming the columns of the fornix.

	Infrastructure - Optical fiber: blown or conventional? (Site not responding. Last check: 2007-10-27)
		This is one of the most widely used methods in the optical fiber cable industry to protect optical fibers from water, temperature and external influences that cause mechanical damage and deterioration of the optical performance of fibers.
		The fibers are broken out from the tube at interconnection boxes, and a furcation or breakout unit may be used to build up the fiber, providing additional protection and strength so a connector can be attached for routing or connection to the end device.
		In the Sumitomo blowing process, where fibers are blown in as a bundle, a tip is placed on the end of the fiber bundle, keeping it from getting caught on the joints of the push-fit connectors where the tube cables connect together.

	Optimized Fiber is suited for high-energy amplification., Liekki Oy
		Fiber has 125 µm cladding diameter and is used for access to wavelengths from IR to UV.
		Typically this fiber is used in lasers for applications in materials processing (cutting, marking, drilling), targeting and range finding, remote chemical detection, and nonlinear frequency conversion for access to wavelengths from the infrared to the ultraviolet.
		Development of a fiber with a large-mode-area and short active fiber length provided the breakthrough required to minimize nonlinear effects, the key limitation on the achievable output energy from conventional fiber amplifiers.

	Randomization :: Randomization in Fiber optics
		Because the fiber bundle is assembled with most individual fibers undisturbed, the resulting output basically mirrors the input, which is non-uniform.
		When the fiber is purposefully mixed (or in fiberoptic terms, randomized), the relative position of each fiber's termination changes from its position at the input.
		Because the randomization process crisscrosses fibers, the technician must exert care to realign the fibers in the input (or output) ferrule.

	A Function-Based Data Model for Visualization
		One element of a fiber is a fiber bundle section.
		The base space is analogous to the independent variables of a function while fiber space is analogous to the dependent variables of a function, and fiber bundle section is analogous to a function (field).
		Therefore, fiber bundle space implies where a function is graphed [Butler and Bryson, 1992].

		The deformed mesh associated with the long-time immersion of the gel fiber in a low-pH environment is shown in Figure 9b.
		However, assuming the fiber bundle functions effectively as a single, large strand, the response time is greatly reduced, as shown to the right.

	Good Math, Bad Math : Twisted Spaces: Fiber Bundles
		A fiber bundle is based on a similar sort of idea: a local property that does not necessarily hold globally - but instead the local property being a property of individual points, it's based on a property of regions of the space.
		So if we try to represent it as a fiber bundle, we'll find that it's a fiber bundle where the base space is a circle, and the fiber is a line segment.
		A fiber bundle is something where the algebra goes this way (moves pointing finger up and down) and the topology goes this way (moves open hand, palm down, in a circle like polishing a table).
