Abstract: Methods and downhole tools for operation within in a wellbore that extends into a subterranean formation. The operation includes simultaneously causing a change in a first parameter of fluid drawn into the downhole tool from the formation and determining a change in a second parameter of the fluid relative to the change in the first parameter. A third parameter of the fluid is determined based on the first and second parameter changes.

Abstract: Disclosed herein is a method of interacting with a wearable electronic device. The wearable electronic device, comprising a vibration sensor, captures vibrations transmitted through a body part on which the electronic device is worn. The vibration can emanate from an object in contact with the user's body or by the motions of the body itself. Once received by the wearable electronic device, the vibrations are analyzed and identified as a specific object, data message, or movement.

Abstract: Disclosed herein is a method and system a system that enables users to simply tap their smartphone or other electronic device to an object to discover and rapidly utilize contextual functionality.

Abstract: A method for collaborative annotating of a program of multimedia content includes enabling a first user to create a program annotation, enabling the first user to store annotation data, and enabling a second user to access the annotation data. The second user may navigate the program using the annotation and/or view the annotation while viewing the program. The first user may create the annotation while viewing the program, for example, by asserting an annotation button on a remote control device. The annotation may include the frame that was displayed when the user created the annotation, text, audio, an image, or video selected by the viewer. The annotations include chronological information indicative of a chronological location of the annotation within the program. The annotations may include “rating annotations” indicating the author's subjective rating of a portion of the program that is in chronological proximity to the annotation's chronological location.

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: 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: The disclosure describes a wearable, low-cost and low-power Electrical Impedance Tomography system for gesture recognition. The system measures cross-sectional bio-impedance using electrodes on wearers' skin. Using all-pairs measurements, the interior impedance distribution is recovered, which is then fed to a hand gesture classifier. This system also solves the problem of poor accuracy of gesture recognition often observed with other gesture recognition approaches.

Abstract: Systems and methods for obtaining in-situ measurements of mixed formation fluids are provided. A downhole acquisition tool may move to a first station in a wellbore in a geological formation to collect a sample of first formation fluid from the first station. The downhole acquisition tool may move to a second station in the wellbore and a sample of second formation fluid may be collected. A proportion of the first formation fluid and the second formation fluid may be mixed within the downhole acquisition tool in-situ while the downhole acquisition tool is within the wellbore to obtain a formation fluid mixture. The formation fluid mixture may be passed into a fluid testing component of the downhole acquisition tool while the downhole acquisition tool is in the wellbore to measure fluid properties of the formation fluid mixture in-situ.

The system and method of the present invention enables high-speed, high precision, and low-cost motion tracking for a wide range of applications.

Abstract: A sensing system includes a sensor assembly that is communicably connected to a computer system, such as a server or a cloud computing system. The sensor assembly includes a plurality of sensors that sense a variety of different physical phenomena. The sensor assembly featurizes the raw sensor data and transmits the featurized data to the computer system. Through machine learning, the computer system then trains a classifier to serve as a virtual sensor for an event that is correlated to the data from one or more sensor streams within the featurized sensor data. The virtual sensor can then subscribe to the relevant sensor feeds from the sensor assembly and monitor for subsequent occurrences of the event. Higher order virtual sensors can receive the outputs from lower order virtual sensors to infer nonbinary details about the environment in which the sensor assemblies are located.
