Abstract: The present invention is an improved corkboard consisting of a small, circular, moveable and removable tack landing pad which is designed to adhere to a flat surface such as a wall or computer by an adhesive strip or to a metal surface like a refrigerator or thing cabinet via a magnetic strip. This landing pad is designed to receive papers of various sizes, shapes, and stock through puncture with a standard push pin tack without damaging walls. The landing pad consists of two components—(1) an outer donut-shaped shell that is sealed at its base and is contoured inward to a narrowing angle at its tack receiving face and (2) an inner foam core. The outer shell operates to both enclose and compress the foam core. This core compression affords the foam greater tack gripping ability as well as enhanced durability by quickly regaining its original shape upon tack removal.

Abstract: An electronic device includes a touch-sensitive surface, for example a touch pad or touch screen. The user interacts with the touch-sensitive surface, producing touch interactions. The resulting actions taken depend at least in part on the touch type. For example, the same touch interactions performed by three different touch types of a finger pad, a finger nail and a knuckle, may result in the execution of different actions.

Abstract: An electronic device includes a touch-sensitive surface, for example a touch pad or touch screen. The user interacts with the touch-sensitive surface, producing touch interactions. Some of these touch interactions may be detected as indicative of a grasp for manipulating a physical tool (e.g., the grasp for holding a pen). When these touch interactions are encountered, a corresponding virtual tool is instantiated. The virtual tool controls an action on the electronic device that is similar to an action that can be performed by the physical tool. For example, the virtual pen can be used to draw on the display, whereas the physical pen draws on paper. A representation of the virtual tool is also displayed on a display for the electronic device, possibly providing additional affordances, at a location that corresponds to a location of the detected touch interaction.

Abstract: A method of synchronizing first and second streams of a multimedia content program is operable for determining a temporal difference indicative of a relative timing between first and second streams of the program, the first stream being provided to a first multimedia processing resource (MPR) and the second stream being provided to a second MPR. The method includes manipulating at least one of the streams to reduce the temporal difference until the temporal difference is less than a predetermined threshold and enabling a viewer of the first stream to interact with a viewer of the second stream regarding the program. Interactions are visually detectable on a first display screen corresponding to the first MPR.

Abstract: A method activates different interactive functions based on a classification of vibro-acoustic signals resulting from touch events with finger parts of a user. A primary function is trigger when an interactive element on a touch screen is touched with a finger tip of the user. An auxiliary function is launched when the interactive element is touched with a knuckle or fingernail of the user. The touch events result in generating the vibro-acoustic signals. The vibro-acoustic signals are classified and used to distinguish what finger part was used based on the classification of the vibro-acoustic signals.

Abstract: An input tool includes a body in the form of a stylus with plurality of vibro-acoustically distinct regions. The vibro-acoustically distinct regions produce vibro-acoustic responses when the regions touch the surface of the touch screen. The vibro-acoustic responses are used in a computing device to detect what region of the input tool was used.

Abstract: Virtual environments are presented on displays along with multimedia programs to permit viewers to participate in a social interactive television environment. The virtual environments include avatars that are created and maintained in part using continually updated animation data that may be captured from cameras that monitor viewing areas in a plurality of sites. User input from the viewers may be processed in determining which viewers are presented in instances of the virtual environment. Continually updating the animation data results in avatars accurately depicting a viewer's facial expressions and other characteristics. Presence data may be collected and used to determine when to capture background images from a viewing area that may later be subtracted during the capture of animation data. Speech recognition technology may be employed to provide callouts within a virtual environment.

Abstract: Accurate, real-time detection of dew point of a gaseous sample can be accomplished using the systems and techniques described herein. A gaseous sampling chamber defining an interior volume includes a patterned structure having a roughened surface exposed to the gaseous sampling chamber. The patterned structure includes an open volume accessible by the roughened surface, for example, representing at least about 10% of the interior volume of the gaseous sampling chamber. An illumination source is configured to illuminate at least a portion of the patterned structure. A light detector is configured to receive at least a portion of illumination returned from the patterned structure. A condensate detector is configured to determine a presence of a condensate on the roughened surface in response to an optical property of the patterned surface as modified by the presence of dew.

Abstract: Methods and devices for mixing a first fluid with a second fluid downhole include a chamber having a first end, a second end and an opening for fluid to flow there through. A top surface of a piston is capable of contacting the second end of the chamber. The piston is located at a first position within the chamber based upon characteristics of a second fluid. A fluid delivery system supplies the first fluid and supplies a second fluid through a first opening of the chamber, wherein the second fluid is at a pressure that moves the piston approximate to the second end of the chamber. The piston includes an agitator mixing device that is attached to a bottom surface of the piston, wherein mixing of the first fluid with the second fluid primarily occurs upon movement of the piston by actuating device.

Abstract: Methods and devices for mixing a first fluid with a second fluid downhole include a chamber having a first end, a second end and an opening for fluid to flow there through. A top surface of a perforated piston is capable of contacting the second end and a top surface of a piston is capable of contacting a bottom surface of the perforated piston. The perforated piston is located at a first position within the chamber based upon characteristics of a first fluid. A first fluid delivery system supplies the first fluid and a second fluid delivery system supplies a second fluid to the chamber, wherein the second fluid is at a pressure that moves the piston approximate to the first end. An actuating device applies a force against the bottom surface of the piston to inject the fluids through channels of the perforated piston to produce spray droplets.
