Granted: 2003-04-22
Abstract: We have found an alkaline warewashing detergent composition that can contain  a critical amount of a nonionic rinse agent that when used in automatic warewashing machines permits the use of a potable water rinse without the addition of a separate rinse agent. Sufficient residual nonionic surfactant from the alkaline detergent remains on the surface ware and internal machine  and rack surfaces after washing to promote adequate sheeting in the rinse cycle. The residual nonionic surfactant on internal surfaces dissolves in th e rinse water to create an effective aqueous rinse agent. The nonionic rinse agents can be a single nonionic for both foam reduction cleaning and sheetin g or can be a blend of nonionic materials providing these functions. The detergent can be in the form of a particulate, pelletized or block solid. Th e detergent can be used in a variety of high temperature and low temperature automatic warewashing machines including large multizone conveyor machines, or relatively small institutional machines that have a single washing chamber.< /SDOAB>

Abstract: A method and system for commanding and controlling diverse home devices. A  first home device capable of displaying user interface data is connected to a home network. A second home device stores user interface data that defines a user interface for commanding and controlling the second home device, also connected to the homenetwork. The first device receives the user interface data from the second device over the network. The first device then displays the user interface as defined by the data. The user interacts with the user interface displayed on the first device by a control device. User input is accepted from the user responsive to the interaction. Control and command information is sent from the first home device to the second home device in order to control the second device according to the user input. Since the user interface can be displayed from any device, a single control device may control a plurality of different devices without requiring any change in the mode of operation of the control device.

Abstract: Méthode pour obtenir par un processus d'inversion, un modèle optimal d'une caractéristique physique dans un milieu hétérogène (l'impédance d'une zone souterraine relativément à des ondes transmises dans le sol, par exemple), en partant d'un modèle a priori de cette grandeur que l'on optimise en minimisant une fonction-coût dépendant des écarts entre le modèle recherché et les données connues, compte-tenu du modèle a priori. - La construction du modèle a priori comporte une corrélation par krigeage entre les valeurs de la grandeur physique connues en différents points du milieu suivant des discontinuités (directions de strates). Les incertitudes sur les valeurs de la grandeur physique dans le modèle a priori par rapport aux valeurs correspondantes dans le milieu obéissent à un modèle de covariance qui contrôle de façon plus quantitative les paramètres d'inversion, les caractéristiques de ce modèle de covariance étant définies en liaison avec la structure des données observées ou mesurées dans le milieu. L'interprétateur est ainsi mieux guidé dans la sélection des paramètres d'inversion. - Applications à la localisation de gisements d'hydrocarbures par exemple.

Granted: 2006-11-28
Abstract: A method and system for an algorithm-based network snoop avoider is provided.  A first data processing system and a second data processing system communicate on a physical network by transmitting data packets on the network using a virtual private network (VPN). Data packets are transmitted through a first VPN tunnel between the first data processing system with a first network address terminating a first end of the VPN tunnel and the second data processing system with a second network address terminating a second end of the first VPN  tunnel. The VPN is automatically reconfigured to use alternate addresses on the network for the tunnel endpoints by automatically determining, in accordance with a predetermined algorithm, a third network address and a fourth network address and by automatically assigning the third network address to the first data processing system and the fourth network address to the second data processing system. Data packets may then be transmitted through a second VPN tunnel in which a first end of the second VPN tunnel is terminated by the first data processing system using the third network address and a second end of the second VPN tunnel is terminated by the second data processing system using the fourth network address. The data packets may be transmitted using Internet Protocol (IP), and a portion of the network may include the Internet.

Title: Method and apparatus for detection of defects in teeth
Inventor: MANDELIS ANDREAS
IPC: A61B6/14
Filed: 2000-07-28
Granted: 2011-04-26
Abstract: There is provided a metrologic methodology and instrument, useful for a high-spatial-resolution dynamic diagnostic metrology and instrument, which can provide simultaneous measurements of laser-induced frequency-domain infrared photothermal radiometry (FD-PTR) and alternating-current (ac) modulated luminescence (FD-LM) signals from defects and caries in teeth intraorally. The combination of the luminescence and radiometric frequency scan techniques for inspection of defects and caries in teeth involves irradiating the tooth with a modulated (direct-current (dc) to 100 kHz) excitation source (laser) emitting in the near-ultraviolet, visible, or near-infrared spectral range, generating blackbody Planck-radiation (infrared radiometry) and ac luminescence, and comparing the obtained (amplitude and phase) luminescence and radiometric signals to those obtained from a well characterized sample (reference) to provide the clinician with numerical information on the status of a tooth. The method and device is used to scan teeth intraorally to detect caries and classify caries or the integrity of the enamel or cementum surface, classify the health and integrity of the enamel at the base of occlusal fissures, classify the health and integrity of enamel or cementum surface of the tooth and defects around the margins of restorations, locate the presence of cracks on the enamel or cementum surface, and locate and characterize cracks in dentin on prepared teeth.

Abstract: A compact expanding gate valve having a valve body defining a flowway and having spaced internal seat rings. Guide elements project internally from the valve body. A valve stem driven gate and segment assembly is movable within the valve body between open and closed positions relative to the seat rings and has control arms mounted by actuating pins to each side of gate and segment members of the gate and segment assembly. The control arms are movable linearly with the gate and segment assembly and are disposed in guided relation with the guide elements during opening and closing movement. During initial movement of the gate and segment assembly from the closed position, the pinned connection of the control arms to the gate member and the segment member causes the control arms to pivot responsive to relative linear movement of the gate and segment members and apply collapsing force to the gate and segment members to collapse the gate and segment assembly to minimize frictional contact thereof with the seat rings and permit its movement by the valve stem from the closed position to the open position.
