An apparatus for indicating photographing conditions within a finder of a camera, including at least one indicator which has a plurality of indicating elements and which represent a single symbol or figure as a whole in the finder field of view, each of the indicating elements indicating an associated photographing condition.

Energy is collected from temperature differentials in a volume of fluid and the energy is used for autonomous propulsion in the fluid.

A clip supports an elongated electrode within a nozzle of an electrosurgical handpiece used in gas electrocoagulation. The clip is preferably formed from a cylindrical tube which has been deformed into a configuration which has a central conduit-like section which engages and supports the electrode and two opposed conduit-like lobe portions which extend outward and slightly compress against the nozzle to hold the electrode and clip in place in the nozzle. The clip is formed by deforming a segmen...

An integrally molded housing having outwardly directed, spaced-apart arms thereon for mounting within or attachment to a panel is disclosed. The arms are located on the body portion of the housing such that a distance slightly less than the thickness of the panel in which the housing is to be received exists between the end of each arm and a circumferential flanged surface on the housing. As the housing is being received through the panel, the arms are deflected inwardly and then spring outwardl...

An everting catheter system which includes an elongated outer catheter having an outer catheter lumen and an opening, an elongated inner catheter movable in the outer catheter lumen and having the inner catheter lumen adapted to receive an elongated instrument and an everting element coupled to the outer catheter and the inner catheter. With movement of the inner catheter in the outer catheter lumen, the everting element can be everted through the opening of the outer catheter. A controller is c...

A device for detecting radiation within a pipe having one or more carriages adapted for movement through the pipe. A set of radiation sensors is mounted on each carriage for detecting radiation on the interior of the pipe. The radiation sensors are positioned to cover a complete circumferential strip on the pipe interior while maintaining the geometry required to meet U.S. government criteria for the unconditional release of the pipe. Readings from the radiation sensors are transmitted out of th...

A method is provided for identifying and locating curves within a digitized image. Digitized images are comprised of points which may represent curves stored as an array of binary coded elements in an memory device. Each addressable memory location in the array represents a single point or pixel. Particular curves within a scanned image are identified by randomly selecting a minimal subset of points which are necessary to generate a general equation for that curve; the equation along with a poin...

A controller for moving an elongated medical instrument in a catheter comprising a supporting structure including a mounting section adapted to be coupled to a catheter and a drive section. The controller also includes a drive wheel and a secondary wheel with each of the wheels having a peripheral surface. Each of the peripheral surfaces has an instrument groove portion. One of the wheels has a circumferential recess in its peripheral surface and the other of the wheels provides a circumferentia...

The dilatation balloon catheter assembly is adapted to be inserted into a blood vessel and comprises a single catheter body having a distal end, a distal end portion, and a proximal end, and a double wall dilatation balloon assembly including an inner inflatable balloon wall and an outer balloon wall with a space therebetween, the balloon walls each having a distal end and a proximal end, and each balloon wall surrounding and being connected at both its distal and proximal ends directly or indir...

A method of suspending an electric submergible pumping system within a wellbore includes inserting an electric cable within a conduit, such as coiled tubing. An electric submergible pumping system is connected to the conduit, and the electric cable is connected to an electric motor of the electric submergible pumping system. The electric submergible pumping system and the conduit are inserted into the wellbore, and the electric cable is permitted to buckle in a manner so that the electric cable ...
