Abstract: An intravascular sensor device can be used to guide treatment of a diseased blood vessel in the body of a patient. In some examples, the intravascular sensor device includes a pressure sensor and an ultrasound transducer. The intravascular sensor device is used to measure a pressure within the diseased blood vessel and acquire an ultrasound image of the diseased blood vessel. The pressure may be measured during hyperemic blood flow that is caused by a pharmacologic vasodilator drug. The measured pressure can be used to calculate a fractional flow reserve value. The ultrasound image can be used to determine a physical dimension of the blood vessel, such as cross-sectional area. The fractional flow reserve value and physical dimensions of the blood vessel can be used to optimize patient treatment.

Abstract: A light system having a hollow housing; a light source provided in the housing; means for mounting the housing to a pool wall or floor; and a lens provided at an open end of the housing, having at least a portion configured to modify at least a portion of the light to match, blend in with, or at least compliment the pool wall or floor; and a flange surrounding the periphery of the lens.

Abstract: A light system having a lens component with at least a portion of the lens configured for receiving an aesthetic material allowing the light system to match, blend in with, or compliment a pool or spa wall or floor, while allowing at least a portion of the light to be emitted into the pool or spa interior, and a housing component for attaching to a pool or spa wall or niche or passage in a pool or spa wall.

Abstract: An implantable medical device (IMD) for gauging the severity of ischemia in a patient's heart includes a data collection module configured to receive data about the patient's heart, a data processing module configured to process the data to identify an episode of ischemia in the patient and to determine if the episode is stable or unstable, and a reporting module configured to provide an alarm to the patient if the episode is unstable. A method executable by an implantable medical device to detect ischemia in a human heart suitably includes the steps of receiving data about the heart at the implantable medical device, processing the data within the implantable medical device to determine the severity of ischemia, and providing a response from the implantable medical device to the patient if ischemia is indicated.

Abstract: A multiple-part hinged bracket assembly for pivotally supporting a toolbox or other container in a slightly elevated position towards the rear of the truck bed, abutting the tailgate. The elevated position allows the full truck bed area to be utilized when hauling large dimensional sheets of material. The toolbox or container is accessible from the rear of the truck in its stored position or outside the truck in the deployed position. The bracket assembly may include a brace that allows the toolbox to be deployed and secured in a preselected pivotal position.

Abstract: The present invention discloses a system and method for cleaning the field lines of a septic tank system. The field lines are outflow pipe fluidly connected to the septic tank. To the field line, there is connected a first pipe and a second pipe or a flush pipe and a vacuum pipe. One of the pipes directs cleaning fluid, usually water, into the field line while the other removes the cleaning fluid and other material from the field line through the field line. A third or valve pipe is added between the first and second pipes and the septic tank. A valve can be placed into the third or valve pipe which is used to close the flow of fluid between the septic tank and the first and second pipes.

Abstract: The present invention provides an apparatus and method for non-invasively monitoring turbulent fluid flows including anisotropic flows. The present invention uses an optical technique to filter out the rays travelling in a straight line, while transmitting rays with turbulence induced fluctuations in time. The output is two dimensional, and can provide data regarding the spectral intensity distribution, or a view of the turbulence in real time. The optical monitor of the present invention comprises a laser that produces a coherent output beam that is directed through a fluid flow, which phase-modulates the beam. The beam is applied to a temporal filter that filters out the rays in the beam that are straight, while substantially transmitting the fluctuating, turbulence-induced rays. The temporal filter includes a lens and a photorefractive crystal such as BaTiO.sub.3 that is positioned in the converging section of the beam near the focal plane. An imaging system is used to observe the filtered beam.

Abstract: A aeration device designed for use in catfish ponds has a support base on which an electric motor and a gear reduction unit are mounted. A cylindrical hub attached for rotation with an output shaft of the gear reduction unit has four evenly spaced radially extending rods. A hollow cylindrical cup is mounted transversely on the free end of each of the rods. The openings of each cup face in the same rotational direction. Four brace struts extend between the radially extending rods, forming a square. In use, the supporting base is situated in a catfish pond, with the motor and gear reduction unit disposed above the water level. At the extreme downward position, each cup will extend about two feet below the water line. As each cup passes through the water, the cup is filled with water which is then carried around a circular arc and dumped from the cup as the cup moves around the arc back toward the surface of the water. In this manner, the water is splashed and aerated before being returned to the water.
