Abstract: There is provided a system and method for automated video segmentation of an input video signal. The input video signal capturing a playing surface of a team sporting event. The method including: receiving the input video signal; determining player position masks from the input video signal; determining optic flow maps from the input video signal; determining visual cues using the optic flow maps and the player position masks; classifying temporal portions of the input video signal for game state using a trained hidden Markov model, the game state comprising either game in play or game not in play, the hidden Markov model receiving the visual cues as input features, the hidden Markov model trained using training data comprising a plurality of visual cues for previously recorded video signals each with labelled play states; and outputting the classified temporal portions.

Abstract: According to some embodiments, in a multi-user detection (MUD) receiver, a method for identifying a beam which produces a specific signal-to-interference-plus-noise ratio (SINR) can include: determining a maximum output SINR; determining beam weights to achieve a target SINR using the determined maximum output SINR; applying the beam weights to one or more received signals to generate a beamformed signal having the target SINR, one or more of the received signals having a signal of interest (SOI), one or more interfering signals, and noise; and providing the beamformed signal to a multi-user detection unit to recover the SOI.

Abstract: A dual barrier side pocket mandrel with gauge includes a gas lift barrier valve mandrel with permanent sensors and at least two pockets for accepting gas lift barrier valves, wherein the pockets are connected via a port. The mandrel also includes a production conduit along a central longitudinal axis. The mandrel is encompassed by a casing on the inside of a well. The permanent sensors can monitor a pressure or a temperature in the casing, production conduit, and port to determine the status of the individual gas lift barrier valves.

Abstract: A system and method for collecting computer application usage data from a plurality of client devices. The system may include a monitoring program executable on each of the plurality of client devices. The monitoring program may be configured to receive from a server via a computer network monitoring data including one or more application identifiers, and to identify one or more target application programs executed on the client device as matching one of the identifiers. The monitoring program may further be configured to gather usage data for the target application program over a period of time, and send a message back to the server including the usage data. Reports may be generated based on the usage data.

Abstract: To apply a resin impregnated fabric to a substrate, a device includes a surface having a layer of material and a first edge. The surface moves relative to the substrate and to conform to the substrate. The layer of material is compatible for use with the resin. The first edge is disposed at the front of the surface relative to the movement of the device to the fabric. The first edge is curved with a center portion of the first edge being relatively forward of a pair of side portions of the first edge.

Abstract: The detergent inhibitor package has been found to influence the viscometric properties of SAE 5W lubricants that have less than 5 mass % of non-conventional basestock, use a basestock that has an average base stock neutral number not less than 105, a calibrated Noack volatility of not more than 22 wt. % loss, and a kinematic viscosity at 100.degree. C. (kV 100, measured by ASTM D445) less than 12.5 cSt. In particular, neutral and overbased calcium salts of organic acids have been found to increase low temperature high shear viscosity when measured in the CCS (ASTM D5293). These salts which are widely used for their detergency and acid neutralization properties should be avoided altogether or used at a level not exceeding 0.0007 moles of organic calcium salt per 100 grams of lubricant. Where diesel performance is required, for example to lubricate passenger car diesel engines, a calcium salt of an organic acid may be required to control piston deposits.
