Title: Understanding effects of a communication propagated through a social networking system
Inventor: LIYANAGE JANAKA
IPC: G06Q30/02
Filed: 2012-08-08
Abstract: Effects of content communications propagated to users of a social networking system may be tracked and measured by the social networking system. Identifiers of content presented to a user within a time period prior to an action performed by the user are recorded in a first label object associated with the action. The action performed by the user generates new content to be presented to other users. The identifiers of the new content and the first label object are recorded in new label objects associated with actions performed by the other users subsequent to viewing the new content. Various metrics may be determined by analyzing the label objects associated with actions performed by users of the social networking system, including virality, reach, and identifying users that share a particular content item.

Abstract: Asparagus spears may be stored and displayed for sale, and sold, in individual containers having a reservoir containing a volume of water, with a group of asparagus spears arranged in the container such that their white tips are in contact with the volume of water. This allows the asparagus spears to be moved from a retail display, to a shopping cart, to a shopping bag, and eventually to a customer's home, without having to remove the white tips of the asparagus from contact with the water. One exemplary container has a waist between the first end and the second end of the container and tapers inwardly from the waist toward the first end and toward the second end. This tapering shape permits air to flow between adjacent containers when the containers are packed together for shipping.

Abstract: A portable system for real time detection of the presence of an infectious agent in a biological sample employs a reagent which detects the presence of a specific infectious agent in the biological sample, and emits a detectable light signal when the reagent reacts with the biological sample and detects the presence of the infectious agent. A test cartridge has a reaction chamber for receiving the biological sample and the reagent. The reaction chamber has a predetermined internal geometry and at least one inner surface. Introducing the biological sample and the reagent into the test cartridge mixes the biological sample and the reagent. A  testing unit receives the test cartridge, and includes a sensor for detecting an emitted detectable light signal. The detection of the emitted detectable light signal is indicative of the presence of the infectious agent in the biological sample.

IPC: F03D3/06

Abstract: A vertical axis wind turbine of FIG. 1 is capable of holding its blades in positively controlled and pre calculated direction while rotating against the in-coming wind to produce the optimum power relative to wind speed resulting in additional torque output as compared to similar size of vertical axis wind turbines. During operation, all the blades of the turbine are in a smooth and continuous movement of changing their angles from  fully open to fully overlap position during each 360 degree rotation of turbine. There are no sudden stops or start points in this angle changing process. This turbine can consist of any number of blades with a minimum of three. This should be decided based on average wind speed where it is supposed to be installed. Smaller number of blades and large surface area in low wind speed and larger number of blades with relatively smaller surface area in high wind speed. This will reduce stalling, typically seen in vertical axis wind turbines. At the heart of this concept are the two box cams which are installed off center  from the main turbine shaft center, one above the blades and the second below the blades mounted on a fabricated steel frame but free to rotate outside the revolving turbine blades as the assembly is mounted on the main turbine shaft with two sealed weather proof bearings. The box cams provide a controlled path to the cam follower bearings mounted on the top and bottom outer edges of each blade. The sections of the box cams that are away from the turbine shaft center makes the blades open wider and produce more positive force from the wind turbine. The sections of the box cams that are closer to the turbine shaft center makes the blades overlap on each other resulting in minimum resistance to the in-coming wind.

Abstract: An improved open-ear hearing aid to compensate for hearing loss includes a microphone 11 for picking up incident sound and converting it to an electrical audio signal. An ear insert 37 positionable within a human ear canal 35 is provided for producing an output sound amplified within one or more frequency bands in response to incident sound picked up by the microphone. The in-band gain of the amplified sound output of the ear insert's loudspeaker 29 is dependent on the user's hearing loss characteristics and the sound pressure levels of the incident sound. The form of the ear insert allows transmission of incident sound directly to the eardrum 39, where it is summed at the eardrum with the amplified sound output from the ear insert. Sound output is maximum at low incident sound pressure levels and minimum when the incident sound exceeds a set cut-off level.

Abstract: Stable, gas-fil!ed bubbles on the surface of proppant particles are formed by placing proppant in selected organic solvent having a much greater solubility of a selected gas compared to water, pressurizing the solvent with the selected gas, e.g., nitrogen, at pressures equal of greater than the operating pressure for a set time period to achieve saturation, and then replacing the solvent with water before reducing the pressure back to operating pressure level to create a local supersaturation near the solvent-solid interface, which will result in gas-filled bubble formation on the surface of proppant particles. The pressurized mixture of bubble surrounded proppant particles and water can then be combined with a respective fracturing fluid, e.g., slick water or carbon dioxide and/or nitrogen foam or an emulsion, which can be used in oil or gas producing wells to improve efficiency of hydraulic fracturing thereof.
