Title: Inter-cache protocol for improved web performance
Inventor: DESIMONE ANTONIO
IPC: G06F17/30
Filed: 1997-09-24
Abstract: On the Internet, different caches may contain copies of objects that have been copied from originating servers when they were accessed by users. Interconnected caches may have different objects stored thereon that might at some time be requested by a client terminal that is connected to a cache other than the one on which the object is stored. Rather than awaiting a request for a particular object and then querying each neighbor cache to determine whether a copy of the requested object is stored thereon, and then downloading the requested object if it is found, information about the contents of the neighbor caches is exchanged between these caches so that when a request for an object is received, the object can be retrieved from the cache in which it is stored. In the alternative, the object may be retrieved from the originating server if, for example, the object stored in a cache is stale based on the date and time it was last modified in the cache.

Patent CA-2216853-A1 (CA)
Inventor: WANG JIN-SHAN
IPC: C08L51/00
Filed: 1996-03-19
Abstract: A new polymerization process (atom transfer radical polymerization, or ATRP) based on a redox reaction between a transition metal (e.g., Cu(I)/CU(II)), provides "living" or controlled radical polymerization of styrene, (meth)acrylates, and other radically polymerizable monomers. Using various simple organic halides as model halogen atom transfer precursors (initiators) and transition metal complexes as a model halogen atom transfer promoters (catalysts), a "living" radical polymerization affords (co)polymers having the predetermined number average molecular weight by .DELTA.[M]/[I]o (up to M n > 10 5) and a surprisingly narrow molecular weight distribution (M w/M n), as low as 1.15. The participation of free radical intermediates in ATRP is supported by end-group analysis and stereochemistry of the polymerization. In addition, polymers with various topologies (e.g., block, random, star, end-functional and in-chain functional copolymers [for example, of styrene and methyl (meth)acrylate]) have been synthesized using the present process. The polymeric products encompassed by the present invention can be widely used as plastics, elastomers, adhesives, emulsifiers, thermoplastic elastomers, etc.

Title: Method and apparatus for correction of colour cast in a digital image
Inventor: SCHISTAD BERNHARD
IPC: G06T7/90
Filed: 1996-06-24
Abstract: The invention relates to a method and an apparatus for the analysis and correction of colour casts in a digitally represented image. According to a preferred embodiment, the crominance contents of the image may be transformed by use of a Hough-transformation or the like transformation, wherein the line structures in the carthesic system of co-ordinates for the crominance content is transformed to a representation in a Hough-diagram in the form of a polar system of co-ordinates, since such line structure is hereby transformed into a point structure. The Hough-diagram is examined with a view to finding a cell in the diagram which has the highest value and the cell found is saved. Subsequently cells are neutralized in the Hough-diagram within a predetermined angular distance, and the Hough-diagram is re-examined with a view to finding that diagram cell which, following neutralization, has the highest value. The cell found is saved and the cells saved which represent the maximae in the Hough-diagram are used to determine the intersecting points for lines in the crominance content system, and said intersecting points are used to evaluate the discolouration of the image.

Title: System and method for optimal logical network capacity dimensioning with broadband traffic
Inventor: HOLDENDER WLODEK
IPC: H04Q3/00
Filed: 1996-07-11
Abstract: A general dimensioning method and system (fig. 19) for allocating limited transmission resources to virtual networks given offered traffic for virtual paths on the virtual networks. The N-layer virtual network dimensioning problem is reduced (1903) to an equivalent virtual path dimensioning problem by collapsing the top three layers of an N-level hierarchichal structure to a two-layer hierarchical structure consisting of the old bottom layer and a new top layer. The new top layer comprises a plurality of virtual routes mapped on the old bottom layer. The resulting virtual route dimensioning problem can be solved (1905) using standard techniques or by using an entropy-based dimensioning algorithm to yield the optimal allocation of resources for layer N-2.

Title: Radio apparatus
Inventor: YOSHIDA HIROSHI
IPC: H03L7/08
Filed: 1998-03-12
Abstract: In a radio apparatus, the band of a loop filter of a synthesizer in a blank channel searching state is narrower than the band in a communicating state. In addition, a radio wave environment is measured. A characteristic necessary for the radio apparatus is determined corresponding to the measured radio wave environment. The power is controlled corresponding to the performance of the radio apparatus. Thus, the power consumption is decreased. In addition, the efficiency of the output power is improved. In the radio apparatus, the current consumption of a power amplifier PA is measured. A matching circuit (LNA or MIX) of the antenna is adjusted with the measured result so as to decrease an antenna loss. In the radio apparatus, a DC offset is removed from the transmitted power and the reflected wave. When the DC offset is removed using an AC coupling capacitor, the deterioration of the frequency characteristic of the receiving portion is compensated with a capacitor in a digital signal process. In the radio apparatus, a transmission power detecting portion is structured as an IC chip. The transmission power detecting portion detects the transmission power corresponding to leakage currents in the power supply of the IC chip and the ground. Thus, when the power is detected, a power loss is suppressed. Consequently, the power consumption of the radio apparatus can be decreased.

IPC: G06F19/00
Filed: 1996-11-13
Abstract: An object oriented approach to virtual motion programming utilizes generic motion identifiers to construct universal generic motion descriptions (102) of complex motien events. A virtual motion controller (110) receives generic motion descriptions and breaks down the descriptions into their constituent parts. The controller (110) expands the generic motion identifiers into general acceleration profiles and processes the general acceleration profiles with the modifiers to generate ideal acceleration profiles that define the acceleration components for the generic motion description with reference to an ideal motion platform (38) having unlimited mechanical movement. The controller (110) translates the ideal acceleration profiles into customized position commands for the motion platform based upon the controller's knowledge of the platform's capabilities.

Title: Log securing device
Inventor: NEVILLE RICHARD L
IPC: F16B15/00
Filed: 1998-06-01
Abstract: An apparatus for securing one log to another during a log machining process. The apparatus has a main body which is shaped in the form of an essentially flat disk. Each side of the disk has at least two protrusions or prongs which are oriented perpendicular to the disk and terminate in a tapered end allowing the protrusion to be driven into a log. The protrusions taper down to a base which is attached to the main body. The main body and protrusions are sized and configured to provide a striking surface between the protrusions to allow a blunt instrument such as a small sledge hammer to be applied to the device to drive it into a log. The device may be further provided with a raised surface portion in the striking surface area, and preferably between the protrusions, to provide a standoff distance between the log and the main body such that the apparatus may be pried loose from the log.

Abstract: A method is provided for a secure transfer of data or data files between participants, subscribers, and users. A first graphic image of the first original form is generated from the first original form of the data file or of the data by a first transformation process. A second electronic seal is generated from the first graphic image in a second step. In the following, the first original form of the data file or of the data and the second electronic seal of the graphic image are transmitted to a receiver. In a further step, the receiver generates a second graphic image of the original form, received at the receiver, with the same transformation process. The receiver generates a fourth electronic seal from the second graphic image, generated by the second transformation process. The transmitted second seal and the newly generated fourth seal are compared to each other with respect to identity in a last step.
