Abstract: Described herein are apparatuses and methods of creating fibers, such as microfibers and nanofibers. The methods discussed herein employ centrifugal forces to transform material into fibers. Apparatuses that may be used to create fibers are also described. To improve the collection of fibers, various devices and systems for controlling the deposition pattern of the produced fibers are described.

Abstract: Provided herein is an inventory management system for dispensing products from an enclosure, methods of securing products within the enclosure, use of the enclosure and for maintaining inventory. The inventory management system may include an enclosure having a self-locking door. The self locking door may include a door, a lock located on the door, a strike plate, wherein the strike plate controls the lock, and a sensor configured to detect the presence of a user and wherein the sensor controls the lock.

Abstract: In one embodiment, a method of dynamic reference plane compensation, comprises impinging radiation from a first radiation source onto a surface of an object; generating an uncompensated measurement signal from radiation reflected from a first location on the surface and a second location; generating a compensation signal from radiation reflected from a third location and a fourth location on the surface; and generating a compensated measurement signal using the uncompensated measurement signal and the compensation signal.

Abstract: A data recovery technique for jitter tolerant peak detected channels. The number of consecutive zeros between ones are reproduced in a run-length coded, peak detected channel. The interval (time, distance) is measured between peaks of a run-length encoded digital data signal wherein peaks represent ones and absence of peaks represent zeros. A look-up-table is provided having entries for all possible intervals between peaks for the run-length code used and corresponding entries for the number of zeros between ones. The measured interval is applied to the look-up-table to produce a string of zero bits between one bits.

Abstract: An input string of binary data bits which is a random sequence of 0s and 1s is selectively spaced encoded into an output string of binary channel bits which is a sequence of 0s and 1s. An input string of binary data bits are recursively encoded according to run-length selection means having rate p/q where p is the number of input data bits that are encoded into q-channel bits. The channel bits obey constraints such that the encoding specifies an ordered n element list of integers that are the lengths of the selected runs of consecutive zeros, denoted b.sub.0 -1, b.sub.1 -1, . . . , b.sub.n-1 -1, and such that the element list of integers does not contain all the integers between the minimum element, b.sub.0, and the maximum element, b.sub.n-1.
