Patent CA-2273576-A1 (CA)
Inventor: OTTENSMEYER PETER
IPC: G01N33/74
Filed: 1999-05-27
Abstract: The 3D structure of the intrinsically dimeric insulin receptor (IR) bound to its ligand, insulin, was determined by electron cryomicroscopy. Insulin labeled with gold served to locate the insulin-binding domain on the 3D structure. The 3D  structure was then fitted with available known high resolution domain substructures to obtain a detailed contiguous model for this heterotetrameric (.alpha..beta.)2 transmembrane receptor. The 3D reconstruction shows that the two a subunits jointly participate in insulin binding and that the two .beta.-subunit kinases in this receptor-ligand complex are in a juxtaposition that permits traps-autophosphorylation of key tyrosine residues in the first step of insulin receptor activation.

Title: Stabilization of fermented dairy compositions using whey from nisin producing cultures
Inventor: BROOKS SCOTT DAVID
IPC: A23C9/158
Filed: 1999-08-27
Abstract: This invention provides stabilized fermented dairy compositions such as yogurt in which the development of excessive acidity and bitter tastes during storage is essentially eliminated. The stabilized compositions are attained by the incorporation of raisin-containing whey derived from a raisin-producing culture. The invention also relates to a method of preparing a fermented dairy product stabilized against the development of excessive acidity, to a method for stabilizing fermented dairy products, and to a method for stabilizing a fermented dairy product against depletion of lactose during storage. The methods comprise adding raisin-containing whey derived from a raisin-producing culture to the fermented dairy product. The whey is obtained from a raisin-producing culture by removing the raisin-producing microorganisms with the curds from the fermentation. The invention further provides methods which yield stabilized fermented dairy products that may be flavored and/or sweetened with syrups.

Patent CA-2285169-A1 (CA)
Inventor: AKIYOSHI TOMOHISA
IPC: B24B1/00
Filed: 1999-10-07
Abstract: An object of the present invention is to provide a method for mirror process of external surface of a long sized metal by which the external surface of a long sized metal can be mirror-processed in high precision and in high efficiency without a surface defect or so that stable dimension accuracy such as a roundness and improvement of yield in production can be obtained.        The method comprises the steps of cramping both ends of a long sized metal such as a round tube or a round bar, charging the long sized metal in the positive electricity and rotating the metal, moving the long sized metal in the axial direction to pass through an electrolytic integrated polishing apparatus for processing the external surface of a long sized metal into a mirror surface. The electrolytic integrated polishing apparatus includes a plurality of grindstones pressed onto the long sized metal from the opposite directions or from outside to the rotation axis radially at a constant pressure, and negative electrodes disposed so that each of the grindstones is disposed between the electrodes in the circumferential direction.        The electrolytic integrated polishing apparatus feeds an electrolyte to the external surface of the long sized metal, and integrates abrasion of the long sized metal by grindstones and concentration elution by an electrolyte for mirror process of the external surface of the long sized metal.

IPC: H04L45/02
Filed: 1999-11-09
Abstract: A virtual network map view of all nodes is provided in a network which is representative of VoIP utilization of the network. As VoIP packets traverse elements of the network, information is stored or logged for use by a network management service. Combined with knowledge of the physical manifestation of the network, the virtual network map is created and used to manage the network as it relates to VoIP traffic.  Other modeled devices such as routers, frame relay access devices (FRADs) and switches complete the picture by representing the logical virtual connections between nodes. A  virtual link between communicating ICS devices is modeled, managed and configured independent of actual multiple and complex real interfaces or links.

Title: Motion vector processing circuit
Inventor: KOBAYASHI MASAYUKI
IPC: H04N19/50
Filed: 1998-06-19
Abstract: A motion vector difference detecting section (10) detects a difference D1 in motion vector between a current frame and a succeeding frame and a difference D2 in motion vector between a preceding frame and a current frame. A latched circuit (50) outputs the motion vector S1 of the inputted current frame as a motion vector S2 in the case where both of the absolute values of the differences D1 and D2 does not exceed a preset value L1, and outputs the motion vector S1 of the frame preceding the corresponding frame as a motion vector S2 in the case where at least one of the absolute values of the differences D1 and D2 exceeds the preset value L1. The latched circuit (50) outputs a motion vector of 0 as a motion vector S2 in the case where both of the absolute values of the differences D1 and D2 exceed the preset value L1 and also the absolute value of the sum of the differences D1 and D2 exceeds the preset value L1. When a change in motion vector is small, dynamic image correction is carried out by the motion vector of the corresponding frame. When a change in motion vector is large, dynamic image correction is carried out by the small motion vector of the preceding frame or the motion vector of 0.

Title: Module-by-module verification
Inventor: LINDHOLM TIMOTHY G
IPC: G06F9/445
Filed: 2000-05-26
Abstract: A method, computer program, signal transmission and apparatus pre-verify instructions in a module of a computer program one module-at-a-time. First it is determined whether checking an instruction in a first module which is loaded requires information in a referenced module different than the first module. If the information is required, a constraint for the referenced module is written without loading or otherwise accessing the referenced module. During linking it is determined whether a first module which is loaded has passed pre-verification one-module-at-a-time before linking. A pre-verification constraint on a constrained module is read, if any, if the first module has passed such verification. If any pre-verification constraint is read, the pre-verification constraint is enforced if the constrained module is already loaded.
