Patent CA-2290952-A1 (CA)
Inventor: YUNG MARCEL MORDECHAY
IPC: H04L9/08
Filed: 1998-05-21
Abstract: L'invention concerne un procédé un système cryptographique à entiercement exempt de traitement non visible, ne nécessitant aucune mise en oeuvre de matériel inviolable (c'est-à-dire que ce système cryptographique peut être réalisé par logiciel). Ce système est en outre vérifiable publiquement, et ne peut être utilisé de façon subliminale pour constituer un système à clés publiques fantôme. Un système à clés publiques fantôme est un système à clé publique non entiercée, qui s'affiche publiquement de façon masquée. Les clés générées par ce procédé sont autorécupérables et autocertifiables (ou ARC). Ce système cryptographique ARC s'appuie sur un mécanisme de génération de clés qui génère une paire clé publique/clé privée, ainsi qu'un certificat prouvant que la clé a été générée conformément à l'algorithme. Chaque paire clé publique/clé privée peut être vérifiée efficacement de manière à être entiercée convenablement par n'importe qui, cette procédure de vérification n'utilisant pas la clé privée. Il s'agit donc d'une manière efficace, pour le grand public, de s'assurer que la clé privée de tout individu est entiercée de manière adéquate, les autorités compétentes étant capables d'accéder à cette clé privée si nécessaire. La vérification pouvant être effectuée par n'importe quel individu, aucune entité compétente spéciale, généralement connue sous le nom de "tiers autorisé", n'est nécessaire. Ce système cryptographique est également exempt de traitement non visible, puisqu'aucune interaction de protocole supplémentaire n'existe entre l'utilisateur qui génère sa propre clé, et l'autorité d'authentification ou les autorités d'entiercement, en comparaison de ce qui est normalement nécessaire pour soumettre la clé publique à des systèmes de clé publique certifiés traditionnels. Ce système est en outre conçu de manière que son fonctionnement interne soit rendu publiquement examinable (il peut par exemple être distribué en format de code source), ce qui diffère des nombreux programmes nécessitant un matériel inviolable pour le dispositif d'entiercement.

Title: Method of forming hydrophilic inorganic coating film and inorganic coating composition
Inventor: INOUE MINORU
IPC: C09D183/02
Filed: 1999-04-12
Abstract: The present invention provides a process for forming a hydrophilic inorganic coated film on a surface of a base material, the process comprising the steps of: (1) preparing an inorganic coating composition which contains, as a major component, a silicone resin obtained by hydrolyzing and condensation-polymerizing only the tetra-functional alkoxysilane represented by the formula:   Si(OR)4 [wherein R represents an alkyl group having 1 to 7 carbon atoms or an aryl group], and has a total solid content of not more than 5% by weight; (2) applying the inorganic coating composition to a surface of the base material to form a coated layer; and (3) drying and curing the coated layer to form a cured coated film having a thickness of 0.01 to 0.5µm. The hydrophilic inorganic coated film formed by the process of the present invention is highly hydrophilic just after the film is formed, even in the case where it is not irradiated with ultraviolet rays.

Title: Initial acquisition and frame synchronization in spread spectrum communication system
Inventor: MOON HI-CHAN
IPC: H04B1/707
Filed: 1999-07-21
Abstract: A device for rapidly performing initial acquisition and frame sync of a received signal for a receiver in a CDMA communication system. To this end, the base station multiplies a spreading sequence for a pilot channel by a sync pattern which maintains the same value for a sequence of a short period and for one period of this sequence but has different value at a boundary of one short sequence period. A mobile station initially calculates the spreading sequence of the short period and the correlation value to perform initial acquisition, and despreads N-chip duration around a boundary of the one short spreading sequence period to detect the multiplied pattern, thereby to acquire sync of a data frame.

Title: Panel testing apparatus and method
Inventor: DUNNE MICHAEL J
IPC: G07D7/182
Filed: 2000-03-30
Abstract: Apparatus and method for non-destructively testing the stiffness of wood panels having opposed panel surfaces and ends. The apparatus comprises a support framework having infeed, centre and outfeed support assemblies mounted to the framework in spaced, successive positions. Each support assembly is adapted to contact the opposed panel surfaces of each panel to define a travel path along which the panel is advanced through the assembly. A first deflection member is provided intermediate the infeed and centre support assemblies and is movable to contact one of the panel surfaces as each panel extends between the infeed and the centre support assemblies with one end of the panel being supported by the infeed support assembly and the opposite end being supported by the centre support assembly. The first deflection member acts to bend the panel to a first pre-determined curvature.      In a similar manner, there is a second deflection member intermediate the centre and outfeed support assemblies movable to contact the same panel surface to bend the panel to a second pre-determined curvature. Load cells associated with the first and second deflection members measure the force require to bend the panels to the pre-determined curvatures for calculation of the stiffness of the panels. The infeed, centre and outfeed support assemblies are movable relative to each other to position the support assemblies such that the travel paths through the support assemblies define a generally "C" shaped path through the apparatus that accommodates the curvatures that each panel adopts in travelling through the apparatus. The apparatus provides a compact panel testing unit by virtue of the novel "C" shaped travel path through the apparatus that is able to operate at the high speeds of a production line.

Title: Apparatus and method for making and dispensing ice
Inventor: HUFFMAN JOHN P
IPC: F25C1/14
Filed: 2000-10-02
Abstract: An ice making device including a control system to regulate the dispensing of manufactured ice to a hopper for subsequent dispensing into a container such as a cup. The control system senses a low level of ice in the hopper and initiates a signal that is sent to a controller. The controller initiates a time delay that prevents discharge of ice from the ice making device to the hopper until a monitored variable about the ice meets a predetermined value. When the value is reached, additional ice is dispensed to the hopper.  Such an ice making device has use in combination with a beverage dispensing device.
