Patent CA-2372263-A1 (CA)
Inventor: FERENCZY MIKLOS
IPC: B64G1/40
Filed: 2002-02-18
Abstract: This invention relates to a Centrifugal Thruster (CT) that utilizes a combination of kinetic energy and centrifugal force to produce net propulsive thrust without generating excessive internal stress on its own structure. This Centrifugal Thruster (CT) produces net propulsive force by running at least one mass - a weight assembly - on a closed loop path where the combined effects of the shape of the path and the varying speed of the weight assembly produce an imbalance of the forces acting in opposite directions at a ratio of 9:1 or better. The weight assembly is in continuous rolling contact with a stationary enclosing path partly to avoid any impact contact (hits), partly to reduce the plucking effect on the drive train and finally to achieve that the generated centrifugal forces are exerted on the stationary path and not on the drive train. The Centrifugal Thruster (CT) is capable to generate larger net propulsive force than its own weight (including a motor) therefore capable of flying or hovering. The major advantage of the Centrifugal Thruster (CT) for space applications is that it does not require propellant since the only energy input is electric power. The Centrifugal Thruster (CT) is primarily intended for space applications such as satellite attitude control and other in-space propulsion tasks. Larger embodiments of the Centrifugal Thruster (CT) will serve as terrestrial launch vehicle thrusters. Based upon prototype test results the Centrifugal Thruster (CT) has such low energy consumption (generated net force/watt) that it offers a possible alternative for the now under development hydrogen powered electric car as well.

Title: Standoff compensation for nuclear measurements
Inventor: MICKAEL MEDHAT W
IPC: G01V5/14
Filed: 2002-04-09
Abstract: A nuclear logging-while-drilling measuring systems, and the correction of the formation property measurements for adverse effects of instrument standoff from the borehole wall, is disclosed. Detector responses for one or more downhole detectors are sampled and recorded over a time segment. The response samples are then sorted by magnitude, and a running integral of the sorted samples as a function of time is performed over the time segment. Linear segments are then fitted to the running integral, wherein each straight line segment is a function of one or more formation properties, and also a function of the standoff distance of the detector from the borehole wall. Segments are then combined to obtain a measure of one or more formation properties of interest such as formation density, where the adverse effects of borehole standoff are minimized. Standoff magnitude is also obtained and can be used to correct other logs, such as a neutron porosity log, for adverse effects of tool standoff and borehole size. No independent caliper of the borehole is required to perform the standoff correction.

Title: Ocular analyte sensor
Inventor: MARCH WAYNE FRONT
IPC: G01N21/64
Filed: 2000-08-24
Abstract: An ophthalmic lens comprising a receptor moiety can be used to determine the amount of an analyte in an ocular fluid.  The receptor moiety can bind either a specific analyte or a detectably labeled competitor moiety. The amount of detectably labeled competitor moiety which is displaced from the receptor moiety by the analyte is measured and provides a means of determining analyte concentration in an ocular fluid, such as tears, aqueous humor, or interstitial fluid. The concentration of the analyte in the ocular fluid, in turn, indicates the concentration of the analyte in a fluid or tissue sample of the body, such as blood or intracellular fluid.

Patent CA-2393473-A1 (CA)
Inventor: KHIEU SITHYA S
IPC: E01C23/22
Filed: 2000-12-12
Abstract: When mounted to a vehicle, a dispenser ejects optical elements so that they have a component of movement that is parallel with the surface of the pavement to which the optical elements are to be applied. Preferably, the component of movement in that direction is more significant than a component of movement directly toward the pavement surface. A fluid assist causes the optical elements to be ejected from the dispenser nozzle at a velocity to at least partially counteract, and preferably match, the forward velocity of movement of the vehicle to which the dispenser is attached. By more closely matching the optical element velocity in a direction opposite the vehicle movement to the velocity of the vehicle, the optical elements can be laid down without substantial roll along the pavement marking material. This can be accomplished regardless of the size or mass of the optical elements.

Abstract: A method and system for generating a user interface for controlling software components through a user control point device. The user interface system provides multiple software components that each can provide a user interface component. Each user interface component provides a user interface for the corresponding software component. A user control point component requests each software component to provide its user interface component. The user control point component then displays an indication of each software component. In response to the selection of a software component, the user control point component requests the user interface component for that software component to display its user interface through the control point device. When a user interacts with that user interface, the user interface component notifies the corresponding software component of the interaction.
