Abstract: The present invention relates generally to methods and compositions for targeting and delivering solid-phase platelet-dependent vascular occlusion agents. In particular, particles or coils or stents coated with platelet binding agents are directed to target vasculature, such as the vasculature of solid tumor masses or AV-malformations or aneurysms or endoleaks; the solid-phase agent then binds and activates platelets, which in turn bind and activate other platelets. This process results in the rapid formation of a platelet-mediated thrombus about the solid-phase agent causing vessel occlusion.

Abstract: A device and method can detect, and also break, an occurrence of gas lock in an electrical submersible pump assembly in a well bore based upon surface or downhole data without the need for operator intervention. To detect an occurrence of gas lock, an instantaneous value is monitored using a sensor. Then a controller compares the instantaneous value to a threshold value over a predetermined duration to thereby detect the occurrence of gas lock in the electrical submersible pump assembly. Sensors can include, for example, a differential pressure gauge, a pressure gage located in a pump stage located toward the inlet, a fluid temperature sensor located toward the discharge, a free gas detector located near the pump discharge, an electrical resistivity gage, a flow meter located within surface production tubing, and a vibration sensor attached to a tubing string to measure a vibration signature.

Title: Playlist processing
Inventor: PUSNIK GORDON
IPC: G11B21/08
Filed: 2009-05-05
Abstract: A play list having an entry that points to a media file in a first format is processed to be played at a client that has a player suitable for rendering files of a second format. A primary description file of the media file is generated at a server. The description file can be used by a second format player to render the first format media file. When a request for the playlist is received at the server from the client, a secondary description file is generated that points to the location of the media file. The server replaces the playlist entry pointing to the media file with an entry pointing to the location of the secondary file. When the client plays the entry from playlist, the client requests and receives the secondary description file, which the client uses to find and render the media file using the second format player.

Abstract: The overflow and underflow effluents of a conventional hydrocyclone are discharged into enclosed vessels, so that the operating pressure may be manipulated for each effluent independently of other operating parameters.  Each of the effluent vessels is equipped with a source of pressurized gas to form a gas blanket over the effluent at a controllable pressure. Such variable pressures in each vessel, in combination with the pressure of the incoming feed stream, provide the necessary parameters to implement pressure-differential-ratio control, thereby improving the efficiency of separation.

Abstract: An oscillator formed from low cost discrete semiconductors and passive devices creates a linear periodic ramp of constant frequency with ramp slope based on an external voltage signal. Parameters are stable over a wide range of temperatures and variations of transistor parameters that normally degrade in extreme environments. The oscillator period can be phase and frequency synchronized to an external clock source over a wide range of frequencies. The oscillator ramp generator phase can be synchronized on a cycle by cycle basis for incorporation in power converters employing spread spectral EMI reduction techniques, multi-converter systems employing clock interleaving for distribution bus filter optimization, and resonant mode converters employing zero voltage switching techniques. Oscillator ramp rate is independent of frequency and can be synchronized to DC (inhibit) for use in ultra low power burst mode power conversion.
