Patent application numberDescriptionPublished
20090126930Cement Composition for Carbon Dioxide Supercritical Environment - The invention provides a cement composition resistant to carbon dioxide including a hollow element for trapping carbonation products. The hollow element can be an additional component added to the cement composition, this component is made of hollow spherical or quasi spherical particles as cenospheres, sodium-calcium-borosilicate glass, silica-alumina microspheres, or a combination thereof. Or the hollow element is a spherical or quasi spherical void made in the set cement, for example by foaming the cement composition with a gas as air, nitrogen or a combination thereof. Use of such cement composition in carbon dioxide application is disclosed. Additionally, a method to cement a part of a borehole in presence with carbon dioxide is disclosed, a method to repair a part of a borehole in presence with carbon dioxide is disclosed using the above cement composition and a method to plug a part of a borehole in presence with carbon dioxide is disclosed.05-21-2009
20100018708Control of the Properties of Cement Slurries of Normal Densities With Optimized Polymers Combination - The invention discloses a cement slurry composition for cementing a well comprising: an hydraulic cement, water and a combination made of a cellulosic polymer and an acrylamido-methyl-propane sulfonate co- or ter-polymer, wherein the density of said cement slurry is above 1700 kg/m01-28-2010

20090295713POINTING DEVICE WITH IMPROVED CURSOR CONTROL IN-AIR AND ALLOWING MULTIPLE MODES OF OPERATIONS - Cursor resolution of a device is based upon a user's gripping (or squeezing) of the device in one embodiment, in accordance with a user's natural usage patterns. In one aspect, a device in accordance with an embodiment of the present invention offers multiple modes of operation depending on its orientation (e.g., which side of the device is facing upward). A device in accordance with an embodiment of the present invention can be used as a mouse, a presentation device, a keyboard for text entry, and so on. In one aspect of the present invention, circular gesture based controls are implemented, specifically for repetitive type functions.12-03-2009
20110248941SYSTEM AND METHOD FOR CAPTURING HAND ANNOTATIONS - A capture device for remote, virtual on screen data input by hand annotation comprises at least three functional layers including a bottom rigid layer, a middle pressure sensor layer and a top flexible layer. The bottom rigid layer has a surface that provides a mechanical support for writing. The middle pressure sensor layer is adapted to measuring a pressure array or map on the capture active area and to send data representing the measured pressure to a personal computer. The top flexible touch-sensitive passive LCD display layer includes an LCD surface by which whatever is written down on the LCD is impressed graphically due to its liquid crystal physical properties wherein applied pressure changes the crystal particles orientation and light properties, such that when a stylus presses against a writing surface thereof, it leaves a visible trace allowing the user to produce a drawing though no real ink has flown.10-13-2011
20120127124Dual Mode Touchpad with a Low Power Mode Using a Proximity Detection Mode - A system includes a touchpad sensor array, a touch circuit, and a proximity circuit. The touch circuit executes a touch mode configured to track the position of a user or conductive object on the touchpad sensor array by detecting a change in an electrical property of the touchpad. The proximity circuit executes a proximity detection mode configured to track the position of a user or conductive object near or proximate to the touchpad sensor array by detecting a change in an electrical property of the touchpad. The system is configured to switch from the touch mode to the proximity detection mode after a predetermined period of inactivity, where the proximity detection mode can operate at one or more reduced polling rates, resulting in a reduced overall power dissipation. The system is configured to switch back to the touch mode when activity is detected by the proximity circuit.05-24-2012
20120206359POINTING DEVICE WITH SOLID-STATE ROLLER - A solid-state roller on a pointing device with enhanced features. The solid-state design described herein allows the sensor to be placed on any shape of surface, such as one that has curvature in two directions. In one embodiment, a trench or downward curve contains sensors for detecting finger movement. The user's finger can thus bend about a knuckle in a curved motion to activate the sensor, requiring little or no movement of the finger up and down. The solid-state sensors can be of one of a number of designs. In one embodiment, multiple electrodes are contacted by a finger as it moves. Each electrode is coupled to a capacitive detection circuit, for detecting the change in capacitance as the electrode is contacted by the finger.08-16-2012
