Abstract: A method and apparatus for producing an organ-sized area of stable microbubble cavitation including insonating an organ of a patient using Low Intensity Non-Focused Ultrasound (LINFU) at a first setting, monitoring the organ to detect presence of desired stable cavitation microbubble resonance and presence of unwanted inertial cavitation, when the presence of stable cavitation microbubble resonance is not detected then adjusting insonation parameters so as to increase the level of insonation, and when inertial cavitation is detected then adjusting the insonation parameters so as to decrease the level of insonation. Related apparatus and methods are also described.

Abstract: A control valve assembly for a fluid treatment system including a valve housing defining a plurality of compartments and a piston assembly associated with each of the compartments. Each of the piston assemblies is configured to be independently movable in each of the compartments. The control valve assembly also includes a gearbox that is associated with the housing and includes a plurality of cams driven by a motor, where each of the cams is configured to drive a corresponding one of the piston assemblies.

Abstract: Systems for controlling the level of water with in reservoir, such as in a catch basin for an infinity pool. One embodiment of such a water level control system comprises a system housing having a removable front plate with front plate openings, and a water inlet into the housing. The system further comprises a removable mounting plate within the housing, with the mounting plate removable from the housing when the front plate is removed. A valve is included that is connected to the mounting plate, with water from the reservoir entering the housing through the front plate openings. The valve is operable to allow water to flow into the housing through the water inlet when water within the reservoir water falls below a desired level, and stopping the flow into the housing when the reservoir is at the desired level.

Abstract: A method and apparatus is disclosed to seal and prevent fluidic communication in the annulus between a cemented and drilled through casing float shoe and a well-bore formation. The present invention provides a component that installs as a coupling unit between a well casing shoe track and a float shoe which integrates a fusible metal alloy. After the well casing is cemented into the well-bore according to conventional procedures, the metal alloy may be melted using a downhole heating device deployed within the casing to a location adjacent to the alloy, thereby causing the alloy to flow, infill, plug and seal any incompetent cracks or micro-annulus conditions within and about the cured cement and well-bore formation.

Abstract: Methods of treating a well bore in a single trip are provided. A tubing string may be inserted into a subterranean formation having a well bore, where the tubing string has a locking device on an end. A workover tool may be positioned in a first zone of the subterranean formation, where the workover tool engages the locking device. One or more perforations may be created or enhanced in a first zone of a subterranean formation using the workover tool, and the tubing string may be positioned in a second zone of the subterranean formation. A fracturing fluid may be introduced into the first zone of the subterranean formation at a rate and pressure sufficient to create or enhance one or more fractures in the subterranean formation. The first zone of the subterranean formation may be isolated from the second zone of the subterranean formation and one or more perforations in the second zone of the subterranean formation may be created or enhanced using the workover tool.
