Visual electrode ablation systems are described herein which include a deployment catheter and an attached imaging hood deployable into an expanded configuration. In use, the imaging hood is placed against or adjacent to a region of tissue to be imaged in a body lumen that is normally filled with an opaque bodily fluid such as blood. A translucent or transparent fluid, such as saline, can be pumped into the imaging hood until the fluid displaces any blood, thereby leaving a clear region of tissue to be imaged via an imaging element in the deployment catheter. An electric current may be passed through the fluid such that it passes directly to the tissue region being imaged and the electrical energy is conducted through the fluid without the need for a separate ablation probe or instrument to ablate the tissue being viewed.

Disclosed is a method for characterizing the content of a digital image. A component of the method is the homogeneity measure, which calculates a value or values based on the local similarity of portions of a sample area. A further component is a means of optimally adjusting the shape and offset of the local sample area to improve the resulting measure. The homogeneity measure may be applied at a higher level to segment an image, by grouping together larger portions of an image whose sub-components are locally similar. A strongly homogeneous region is a contiguous region composed of elements exhibiting local homogeneity better than that of surrounding elements, and may be applied to identify the scale and other characteristics of a portion of an image. This may be used to facilitate algorithms that separate lighting and texturing information, and in identifying the composition of an image.

A platform cooling structure for a gas turbine moving blade is provided which is capable of improving cooling performance of a platform and of improving reliability of a moving blade in such a manner that a portion in the vicinity of a side edge of the platform which is away from moving blade cooling passageways and is easily influenced by thermal stress caused by high-temperature combustion gas, that is, an upper surface of the side edge is effectively cooled by guiding high-pressure cooling air, flowing to the moving blade cooling passageways, to a discharge opening formed in a surface of the platform in the vicinity of the side edge of the platform without particularly attaching an additional member such as a cover plate to the platform. A moving blade cooling passageway 17c is formed in the inside of the gas turbine moving blade. Cooling communication holes 24a and 24b, of which one ends communicate with the moving blade cooling passageway 17c and the other ends communicate with a plurality of discharge openings 22 provided in the surface of the platform in the vicinity of the side edge of the platform 5, are formed through the inside of the platform.

The forward-looking sonar further includes a position measurement section for determining the position of a target based on the direction of the target calculated from a phase difference between the echoes from the target received by the first and second receiving beams by a split-beam method and the distance to the target calculated from time needed for receiving the echoes after transmission.

Selectable objects in a computer display are arranged in a cascading menu including parent menu and submenu objects in which an activation area is provided in association with each submenu displayed which spans between the submenu and the associated parent menu object. The activation area provides the function of maintaining display of a submenu associated with a selected parent menu object while the cursor remains in contact with the activation area. An override function is provided to minimize trapping of the cursor within the activation area. The shape of the activation area is generally triangular with opposing side edges extending from an apex and the parent object being curved inwardly towards one another to also minimize trapping. The characteristics of the activation area can also be varied according to user motion patterns.

Nondestructive material condition monitoring and assessment is accomplished by placing, mounting, or scanning magnetic and electric field sensors and sensor arrays over material surfaces. The material condition can be inferred directly from material property estimates, such as the magnetic permeability, dielectric permittivity, electrical property, or thickness, or from a correlation with these properties. Hidden cracks in multiple layer structures in the presence of fasteners are detected by combining multiple frequency magnetic field measurements and comparing the result to characteristic signature responses. The threshold value for indicating a crack is adjusted based on a high frequency measurement that accounts for fastener type. The condition of engine disk slot is determined without removal of the disk from the engine by placing near the disk a fixture that contains a sensor for scanning through the slot and means for recording position within the slot. Inflatable support structures can be placed behind the sensor to improve and a guide can be used to align sensor with the slot and for rotating the disk. The condition of an interface between a conducting substrate and a coating is assessed by placing a magnetic field sensor on the opposite side of the substrate from the coating and monitoring at least one model parameter for the material system, with the model parameter correlated to the interfacial condition. The model parameter is typically a magnetic permeability that reflects the residual stress at the interface. Sensors embedded between material layers are protected from damage by placing shims on the faying surface. After determining the areas to be monitored and the areas likely to cause sensor damage, a shim thickness is determined and is then placed in at least one area not being monitored by a sensor. The condition of a test fluid is assessed through a dielectric sensor containing a contaminant-sensitive material layer. The properties of the layer are monitored with the dielectric sensor and correlated to contaminant level.

A novel system and method of treating the output of moving cameras, in particular ones that enable the application of conventional “static camera” algorithms, e.g., to enable the continuous vigilance of computer surveillance technology to be applied to moving cameras that cover a wide area. According to the invention, a single camera is deployed to cover an area that might require many static cameras and a corresponding number of processing units. A novel system for processing the main video sufficiently enables long-term change detection, particularly the observation that a static object has been moved or has appeared, for instance detecting the parking and departure of vehicles in a parking lot, the arrival of trains in stations, delivery of goods, arrival and dispersal of people, or any other application.

A false eyelash that is easily wearable and prevented from slippage and separation while in use includes an extremely thin base, bonding layer formed linearly on a surface of the base, a plurality of hair segments individually and separately adhered to the bonding layer, and an adhesive layer formed on an entire underside of the base. The base is formed into substantially a two-dimensional configuration or three-dimensional configuration that contours a curved shape of an eyelid to which the base is fitted. Since the base is formed into an extremely thin two-dimensional configuration or a three-dimensional configuration that contours a curved shape of the eyelid, it may be fitted tightly to the eyelid. The hair segments are firmly adhered to the bonding layer such that they remain linearly attached to the base, by which the false eyelash with the well-aligned hair segments can easily be fitted to the eyelid.

The device can include a first member connected to a second member via junctions.
