Patent CA-2319239-C (CA)
Inventor: WOOD STEVEN WILLIAM
IPC: G11C8/18
Filed: 1996-05-15
Granted: 2004-03-30
Abstract: A multi-port RAM (random access memory) including an array of RAM cells. Each RAM cell has a core cell with a single-ended, pseudo-differential write access port and differential, indirect access read ports.      The architecture of the features of the mufti-port RAM allows direct scaling of the number of write and read access ports to any practical limit with no adverse effects on cell stability margins and therefore data integrity. Also, disclosed is a design detail for an innovative time multiplexed read port architecture implemented as part of a high-speed 9-port time slot interchange random access memory. It provides a practical, high-speed, low-power and area efficient read port structure to allow eight random access reads per clock cycle. Because all timing is internally generated from a single rising clock transition of a system clock signal, no special control or clocking is required externally to the memory.

Granted: 2006-01-03
Abstract: A common power control channel transmission device for a base station in a CDMA communication system is provided having a selector (350) for receiving power control commands to be transmitted to multiple subscribers and multiplexing the received power control commands; and a spreading modulator (372) for spreading an output of the selector by multiplying the output of the selector by a spreading sequence. The common power control channel transmission device can be used to control power of a reverse link common channel. For the power control of the reverse link common channel, the base station receives a signal from a mobile station via the reverse link common channel, and transmits to the mobile station a power control command for controlling a transmission power of the reverse link common channel according to a measured strength of the received signal.

Title: Dispositif et procede de surveillance non invasive de la pression sanguine arterielle d'un sujet
Inventor: FINBURGH SIMON E
IPC: A61B5/022
Filed: 1999-07-15
Granted: 2005-03-29
Abstract: L'invention concerne un dispositif permettant de contrôler de manière non invasive la pression sanguine d'un sujet. Dans ce dispositif, un système (14) de capteur de pression comprenant un transducteur (50) de pression est pressée contre les tissus recouvrant une artère, avec une force suffisante pour comprimer cette artère. Un premier système de servocommande à moteur (32) réalise un degré optimal de compression artérielle, qui correspond à une pression transmurale moyenne d'environ 0, en modulant un côté d'un bras (36) de levier qui presse le système contre les tissus, générant ainsi un signal de pression indiquant une pression transmurale. Etant donné que différents effets de pression se produisent selon le degré de compression artérielle, le dispositif peut générer un signal de commande approprié afin qu'un second moteur (34) ajuste l'autre côté du bras (36) de levier de manière à obtenir une pression optimale du système sur les tissus recouvrant l'artère. Le dispositif est positionné de manière optimale sur une artère grâce à un capteur de débit sanguin intégré, conçu pour détecter le débit sanguin sous le transducteur de pression.

Abstract: A method and apparatus for steady-state target calculation that explicitly accounts for model uncertainty is disclosed. In accordance with one aspect of the invention, when model uncertainty is incorporated, the linear program associated with the steady-state target calculation can be recast as a highly structured nonlinear program. In accordance with another aspect of the invention, primal-dual interior point methods can be applied to take advantage of the resulting special structure. For a system having characteristic gain parameters G having a known uncertainty description, the present invention provides a method and apparatus for selecting steady-state targets for said system-manipulated variables such that all system-controlled variables will remain feasible at steady-state for all possible values of the parameters G within the known uncertainty description. A  nominal estimate ~ of the system parameters G is made, and in accordance with another aspect of the invention, the steady-state targets are selected such that when ~ = G, the system is driven to an operational steady-state in which the objective function is extremized.

Abstract: The dispenser (10) is of an ergonomic shape, provides for single hand use. The dispenser has a barrel (12) closed at one end and an angled barrel extension at another end. The push button actuator (30) to dispense the product is located in the barrel extension (14). On the upper end of the barrel extension is an applicator surface (18). A semisolid liquid is stored in the barrel (12). Upon pressing the actuator (30) the elevator (22) rises upwardly with the semisolid liquid passing through conduits (32) to the applicator surface. It then is applied to the skin. The pressing of the actuator (30) causes a threaded rod (40) to rotate which raises the elevational. By placing the actuator (30) at a mid to upper part of the dispenser, the dispenser can be gripped with the thumb on the actuator (30) and the other fingers passing behind the barrel of gripping. The actuator (30) can be operated without changing the position of the dispenser in the hand.

Abstract: The invention relates to a machine for drilling oil holes in crankshafts and to a corresponding method. Said machine can drill one, two or more crankshafts per cycle. Each crankshaft can rotate around its own axis. The assembly described in the invention is mounted on a revolving plate with a horizontal work top and a vertical rotational axis to place the crankshafts at different angles relative to the Z axis of the machining module while preserving the horizontality of the longitudinal axes of the crankshafts. The machining module is located facing the assembly and is fitted with two horizontal axis spindles, a drilling tool holder and the corresponding drill bit guides that are placed parallel to one another, are mounted one on top of the other and at the same distance as the two crankshafts. The module moves along three coordinates: an X (horizontal-transversal) axis, a Y (vertical ) axis and Z (horizontal-drill bit advance feed) axis. A fourth W axis (with an additional carriage and independent actuation) moves parallel to the Z axis and serves as a support for the drill bit guide bushings. The machine is fitted with an automatic changer (of the drill bit and guide bushing or the guide bushing only) and encompasses simultaneously the pair of tool holder spindles. The invention can be used in the field of machine tooling.

Granted: 2009-05-12
Abstract: A solvent-free polyurethane-polymer hybrid dispersion having a high solids content of polymer or formulation constituents is described, which is obtainable by a) the multistage preparation of a polyurethane base dispersion and b) by the subsequent preparation of a polyurethane--polymer hybrid dispersion.     This polyurethane-polymer hybrid dispersion not only is distinguished by complete freedom from solvents and high solids contents in combination with low viscosity and a technically simple preparation process but also has excellent mechanical properties and, owing to the low hydrophilicity, high water resistance. The polyurethane-polymer hybrid dispersion proposed according to the invention can be used in an outstanding manner in formulations for sport floor coverings, said dispersion being suitable in particular as a binder for resilient coats, as a spray or leveling coating on resilient or rigid substrates, as an adhesion promoter or primer, as filling compounds for sealing pores, as adhesive for the adhesive bonding of prefabricated resilient layers or for the sealing of sport floor coverings.
