A microflow device for separating or isolating cells from a bodily fluid or other liquid sample uses a flow path where straight-line flow is interrupted by a pattern of transverse posts which are arranged across the width of a collection region in an irregular or set random pattern so as to disrupt streamlined flow. Sequestering agents, such as Abs, are attached to all surfaces in the collection region via a hydrophilic permeable hydrogel coating. The collection region is formed as a cavity in a body molded from PDMS, which flexible body is sandwiched between a glass slide or comparable flat plate and a rigid top cap plate, both of which are pressed into abutting relation with the PDMS body by a heat-shrunk polymeric sleeve. Following cell separation and washing, cells can be released from the sequestering agents and the device centrifuged to force said cells to collect adjacent the hydrogel-coated slide or plate. Slitting the polymeric sleeve allows the body to then be peeled from the slide or plate, using an integral tab, to expose the separated cells on the top surface thereof for ready microscopic examination.

A random array of holes is created in an optical fiber by gas generated during fiber drawing. The gas forms bubbles which are drawn into long, microscopic holes. The gas is created by a gas generating material such as silicon nitride. Silicon nitride oxidizes to produce nitrogen oxides when heated. The gas generating material can alternatively be silicon carbide or other nitrides or carbides. The random holes can provide cladding for optical confinement when located around a fiber core. The random holes can also be present in the fiber core. The fibers can be made of silica. The present random hole fibers are particularly useful as pressure sensors since they experience a large wavelength dependant increase in optical loss when pressure or force is applied.

A method for allowing user access to a resource includes a large number of arrays of elements which are generated and stored for each user for use in a series of log-in sessions. A user input token is calculated by identifying a subset of the array by a pattern of the elements in the array, combined in an operation on the elements selected using one or more mathematical, relational and / or logical operations. The arrays are stored in a table with the tokens calculated from those arrays and withdrawn in a random pattern for use in the sessions for that user. Each array includes multiple possible solutions including the actual solution using the pattern and calculation of that user and these other possible solutions act as hacker traps to indicate the presence of a hacker who has calculated a solution but found the wrong solution

Techniques for determining authenticity of analog forms such as packaging or documents (117). One of the techniques determines whether the analog form has been made directly from a digital representation (903) or by photocopying or scanning an analog form. The technique makes the determination by comparing (911) an original digital representation of a portion of the analog form with a digital recording (203) of the portion from the analog form and measuring differences in features that are affected by the operations of photocopying or scanning. The original digital representation (105) and the analog form may have a “noisy”, i.e., random or pseudo random pattern. Such noisy patterns may further be used for other authentication purposes, such as determining whether the portion of the analog form that has the noisy pattern has been altered and to carry hidden messages. The noisy pattern may carry a logo or may be part or all of a barcode.

In a method for the continuous real time tracking of the position of at least one mobile object in a defined multidimensional space, at least one mobile transmitter module is attached to at least one mobile object and the signals from the at least one module are received by a stationary receiving and signal processing network and then centrally processed. The signals emitted by each transmitter module are electromagnetic waves sent within a frequency band range using time division multiplexing techniques. Due to the fact that the frequency band is used as a single channel for the purpose of maximizing the accuracy with which a position is detected, and due also to the fact that the communication process between the transmitters and the receivers is based on the principle of pseudo-random time division multiplexing using burst transmissions of low cross correlation with non synchronized pseudo-random patterns, there is created a method for the continuous tracking of the position of one or more mobile objects at any time and in any place which is of very high positional resolution and has a temporal resolution of just a few milliseconds.

A method for encryption data subdivided into segments of random lengths. A data source having a state corresponding to initialization parameters and the number of patterns output therefrom provides for a reversible encryption process. Decryption is accomplished by repeating encryption using a data source having an identical initial state. The data source consists random pattern generation machines (RPGMs). A portion of RPGMs may each contain patterns of a different length. Randomly selecting an RPGM and outputting a pattern therefrom effectively provides a pattern of random length. The data source may output patterns interpreted to govern the behavior of obfuscation operations. Patterns output from the data source may be interpreted as instructions as to what obfuscation to perform and what parameters shall define the obfuscation.
