Abstract: Image data is processed by identifying a region of substantially constant colour within a first image. Colour variations, in terms of standard deviation about an average colour, are analysed and a similar level of variation is applied to a second image. The first image may be derived from cinematographic film, with colour variations due to film grain. The second image may be a video image or a computer generated image and the application of a similar level of variation may reproduce noise similar to that present within the film due to grain. In this way, it is possible to add grain to non-filmed images so as to match said images to images derived from film.

Abstract: The timing of an access burst received in a base station of a wireless communications system is determined by detecting one or more zero bit fields, constituting predetermined sequences of identical consecutive symbols in the access burst. For each possible timing of the access burst, whether a predetermined sequence is present in the respective position in the access burst is detected by predicting a sample of the received signal in the current symbol period from a sample of the received signal in the preceding symbol period assuming identity of symbols in the current and preceding symbol periods, producing a squared distance between predicted and received samples for the current symbol period, producing a threshold in dependence upon a power of the received signal for the preceding symbol period to accommodate fading, and comparing the squared distance with the threshold, continuing for successive current symbol periods until the end of the sequence or until the respective threshold is exceeded. The squared distances are accumulated for each possible timing, the least accumulated squared distance determining which of the possible timings for which the predetermined sequences are detected, if there is more than one, is the access burst timing.

Title: Peanut allergens and methods
Inventor: STANLEY J STEVEN
IPC: C12N15/29
Filed: 1996-09-23
Granted: 2008-12-02
Abstract: Peanuts are a common cause of food hypersensitivity reactions. The sera of 10 patients who had atopic dermatitis and a positive double-blind placebo-controlled food challenge to peanut were used to investigate the major allergens of peanut. Crude Florunner extracts were fractionated by anion-exchange chromatography using a step gradient (limit buffer, 0.05M BisTris/1.5M NaCl). A protein peak (OD 280) which eluted at 10t NaCl and demonstrated intense IgE-binding was further analyzed by two-dimensional SDS-PAGE/immunoblot analysis. The majority of this fraction is a protein which has a molecular weight of 17 kD and a pI of 5.2. Sequencing data from the N-terminus revealed the following initial 9 amino acids: (*)-Q-Q-(*)-E-L-Q-D-L. Based on IgE-binding activity and no known amino acid sequence identity to other allergens, this allergen is designated Ara h II. Ara h II may be used to detect and quantify peanut allergens in foodstuffs. Serum IgE from patients with documented peanut hypersensitivity reactions and a peanut cDNA expression library were used to identify clones that encode peanut allergens. One of the major peanut allergens, Ara h I, was selected from these clones using Ara h I specific oligo-nucleotides and polymerase chain reaction technology. The Ara h I clone identified a2.3 kb mRNA species on a Northern blot containing peanut poly A+RNA. DNA sequence analysis of the cloned inserts revealed that the Ara h I allergen has significant homology with the vicilin seed storage protein family found in most higher plants. The isolation of the Ara h I clones allowed the synthesis of this protein in E. coli cells and subsequent recognition of this recombinant protein in immunoblot analysis using serum IgE from patients with peanut hypersensitivity.

Title: Communication network system and method for controlling communication path thereof
Inventor: UWAJIMA KAZUO
IPC: H04L69/40
Filed: 1997-11-12
Granted: 2002-10-15
Abstract: Method for restoring the communication to a normal one when one unit network has a defect in a communication network system which is constituted of a plurality of unit networks. Unit networks are connected with internetwork connection circuits. Usually, communication is done in each unit network via a communication path which is formed by looping back remote communication devices at both ends of the unit network. When a defect such as the cut of a communication line occurs in a certain unit network, the loopback of the remote communication devices at both ends of the unit network which has the defect is canceled for the internetwork connection circuits and then an alternate communication path is formed. Using the alternate communication path, communication is done between local communication terminals which are adjacent to the defective point.

Abstract: A process for the separation of propylene from an input stream of C3 hydrocarbons containing propylene, possibly C4 and/or higher hydrocarbons, and MAPD (methyl acetylene and/or propadiene), comprises subjecting said input steam to fractional distillation to separate the propylene as an overhead stream leaving a bottoms stream containing said MAPD and any C4 and/or higher hydrocarbons. In order to avoid the need to slip substantial amounts of valuable propylene into the bottoms stream to maintain the concentration of MAPD in the bottoms stream at a safe level, a propane-containing stream is added to the input stream of C3 hydrocarbons so that the bottoms stream contains a substantial amount of propane. So that the propylene content of the bottoms stream can be maintained at below 10% by weight, the amount of propane added to the input stream is such that the weight of propane, plus any propylene and C4 and/or higher hydrocarbons, in said bottoms stream is greater than the total weight of MAPD in said bottoms stream.
