Abstract: A method of pumping an oilfield fluid from a well surface to a wellbore is provided that includes providing a clean stream; operating one or more clean pumps to pump the clean stream from the well surface to the wellbore; providing a dirty stream including a solid material disposed in a fluid carrier; and operating one or more dirty pumps to pump the dirty stream from the well surface to the wellbore, wherein the clean stream and the dirty stream together form said oilfield fluid.

Abstract: A method and apparatus for harvesting energy comprising determining an electrical impedance of a piezoelectric stack, connecting an electrical load to the piezoelectric stack wherein the piezoelectric stack is housed in a mechanical amplifier comprising a fixed supporting member, a movable supporting member connected to compliant links attached to at least one actuating arm, and connecting the actuator to a source of motion whereby movement of the actuating arm results in compression and expansion of the piezoelectric stack, which generates electrical current into the electrical load.

Abstract: A system and method for detecting, analyzing, and controlling the content of computer files and information in a variety of formats, including embedded information. The system examines one or more computer files in their entirely, including any embedded files, objects, or data, looks of confidential or secret information according to an established security search protocol, which may vary from user to user. Objects in a computer file are identified and decomposed into component objects. This process can be repeated until a user-specified depth of decomposition is achieved, or until the component objects can no longer be decomposed. The component objects are then analyzed for specific content, which is displayed for review by the user. The user can then make decisions regarding removal or modification of that content before sending the file on for further processing or delivery to a recipient.

Abstract: The present invention provides polymeric compositions having a high polymer size and a low Tg. These novel compositions are useful as plastic additives. Also provided is a method of improving the processing of a matrix resin by adding one or more of the novel polymeric compositions.

Abstract: A glass patch cellular antenna is provided which can be imprinted as a thin film element on the interior surface of an automobile window. The antenna is physically configured to serve as a coupling element for an optional antenna mast which can be mounted externally on the window opposite the antenna. As a thin film element, the antenna can be factory installed and prewired such that the automobile is cellular ready, in that the installation of an external mast is unnecessary to achieve suitable performance. Yet, an external mast can be readily coupled with the antenna in order to enhance the performance capability of the antenna.
