Title: Optical system employing near-incoherent processing for distortion correction
Inventor: FARINA JAMES D
IPC: H04B10/61
Filed: 1996-01-30
Granted: 2001-04-17
Abstract: A system for correcting nonlinear distortion in fiber optic systems including communication systems by means of light modulation provided by interferometric modulators such as the Mach-Zehnder. The present invention involves the addition of a correction signal which contains error canceling information.  The additive correction signal optical beam is frequency shifted or phase scrambled through the use of a phase or frequency modulator. This insures the corrective light signal adds incoherently or quasi-incoherently within the signal bandwidth of interest. Furthermore, the present system rquires only a single light source and can be made independent of wavelength and is easily optimized with active servo devices. A system provided by the present invention also provides improvement over the state of the art because of its high degree of correction and independence from link length using ordinary single mode fibers.

Granted: 2008-09-02
Abstract: The surface of a substrate is coated with an abrasion-resistant photocatalytic coating comprised of a semiconductor photocatalyst. Upon irradiation by a light having a wavelength of an energy higher than the bandgap energy of the photocatalyst, water is chemisorbed onto the surface in the form of hydroxyl groups (OH-) whereby the surface of the photocatalytic coating is rendered highly hydrophilic. In certain embodiments, the surface of a mirror, lens, or windowpane is coated with the photocatalytic coating to exhibit a high degree of antifogging function. In another embodiment, an article or product coated with the photocatalytic coating is disposed outdoors and the highly hydrophilic surface thereof is self-cleaned as it is subjected to rainfall. In a still another embodiment, an article is coated with the photocatalytic coating and, when the article is soaked in, rinsed by or wetted with water, fatty dirt and contaminants are readily released without resort to a detergent.

Granted: 2003-03-25
Abstract: A  binary  arithmetic  coder  and  decoder  provides improved  coding  accuracy  due  to  improved  probability estimation and adaptation.  They also provide  improved decoding  speed  through  a  "fast  path"  design  wherein decoding  of  a  most  probable  symbol  requires  few computational steps. Coded data represents data that is populated  by more  probable  symbols  ("MPS")  and  less probable symbols  ("LPS").   In an embodiment, a decoder receives  a  segment  of  the  coded  data  as  a  binary fraction C.   It defines a coding interval of possible values  of  C,  the  interval  extending  from a  variable lower bound A to a constant upper bound 1.   For each position  in  the  decoded  symbol  string,  the  decoder computes  a  test  value  Z  that  subdivides  the coding interval  into sub-intervals according to the  relative probabilities  that  an  MPS  or  an  LPS  occurs  in  the position.   A first sub-interval extends from the lower bound A to the test value Z;  the second sub-interval extending from the test value Z to 1.   If C is greater than  Z,  the  decoder  emits  an  MPS  for  the  current position in the decoded symbol string and sets the lower bound A to the test variable Z for use during decoding of the next position in the decoded symbol string.  If C is less than Z, the decoder emits an LPS and computes a new lower bound A and a new binary fraction C for use during  decoding  of  the  next  position  in  the  decoded symbol  string.    The  encoder  operates  according  to analogous techniques to compose coded data from original data.

Abstract: A vehicle seat is provided for use in a vehicle including floor means having a pair of front and rear wells and anchor members extending across the wells. The seat is movable between a fixed, operative position and forwardly tumbled, storage position. The vehicle seat includes a pair of rigid support structures disposed on opposite sides of the vehicle seat. Front and rear legs are mounted on each of the pair of rigid support structures.      Each of the legs includes a front and rear hook member for latching and unlatching the seat with respect to the anchor members. Each of the rear legs is pivotally coupled to an associated rigid support structure so as to be movable between (1) an operative position extending generally downwardly with respect to an associated rigid support structure, and (2) a forwardly folded position disposed generally adjacent an associated rigid support structure.      Handle structure is coupled to at last one of the rear legs in a position to be manually grasped and operated at a side of the vehicle seat for unlatching the rear hook members thereby permitting the vehicle seat to be pivoted about the front anchor members and moved to the forwardly tumbled, storage position thereof.      The handle structure includes a lost-motion connection constructed and arranged such that when the rear legs move toward the forwardly folded position thereof causing a portion of the handle structure to contact a surface of an associated rigid support which would otherwise restrict movement of the rear legs, the lost-motion connection permits the handle structure to move, enabling the rear legs to complete movement to the forwardly folded position thereof.

Abstract: The invention relates to a recyclable aluminum foil. The foil is made of an alloy containing 0.2 %-0.5 % Si, 0.4 %-0.8 % Fe, 0.1 %-0.3 % Cu, and 0.05 %-0.3 % Mn by weight with the balance aluminum and incidental impurities. The foil contains at least about 2 % by weight of strengthening particulates and has at least about 0.1 % by weight of the copper and/or manganese retained in solid solution. The invention also relates to a method of manufacturing a sheet of aluminum based on an alloy which involves continuously casting an alloy of the above composition to form a sheet of alloy, coiling said sheet of alloy, cold rolling the sheet of alloy, interannealing the alloy after a first pass of the cold rolling; and further cold rolling the alloy to a final desired gauge. The foil, which is suitable for household use, has improved strength due to a larger quantity of dispersoids fortified by elements in solid solution, and can be recycled with other alloy scrap.
