At the present time, physicians often treat patients with atrial fibrillation (AF) using radiofrequency (RF) catheter systems to ablate conducting tissue in the wall of the Left Atrium of the heart around the ostium of the pulmonary veins. These systems are expensive and take time consuming to use. The present invention circular ablation system CAS includes a multiplicity of expandable needles that can be expanded around a central axis and positioned to inject a fluid like ethanol to ablate conductive tissue in a ring around the ostium of a pulmonary vein quickly and without the need for expensive capital equipment. The expansion of the needles is accomplished by self-expanding or balloon expandable structures. The invention includes centering means so that the needles will be situated in a pattern surrounding the outside of the ostium of a vein. Also included are members that limit the distance of penetration of the needles into the wall of the left atrium, or the aortic wall. The present invention also has an important application to ablate tissue around the ostium of one or both renal arteries, for the ablation of the sympathetic nerve fibers and / or other afferent or efferent nerves going to or from each kidney in order to treat hypertension.

Connector for connecting a pair of tubular components together, such as a pair of exhaust conduits of a dryer or an exhaust conduit of a dryer to a dryer vent or wall-mounted vent sleeve, including a pair of generally semi-cylindrical members each having a first, coupled edge and a second, free edge and rotatably connected together at the coupled edge, e.g., by a hinge, and separable from one another at the free edge. A quick connect / quick disconnect locking structure is arranged in connection with the semi-cylindrical members for locking them to one another with the free edges opposite one another.

A turbine blade for a turbine engine having a leading edge cooling system formed from a suction side cooling channel and a pressure side cooling channel. Cooling fluids flow into the leading edge cooling channels through impingement orifices that meter cooling fluid flow. The cooling fluids may form vortices in the cooling channels before being released from the turbine blade through gill holes. The cooling fluids then form a boundary layer of film cooling fluids on an outer surface of the turbine blade.

A backlight unit for a liquid crystal display device including a liquid crystal panel, includes: a light source including a light-emitting diode (“ED”) which generates and emits light; and a light converting layer between the light source and the liquid crystal panel, spaced apart from the light source, and converting the light from the light source into white light and emitting the white light toward the liquid crystal panel. The light converting layer includes: semiconductor nanocrystals, and a barrier material which restricts penetration of moisture or oxygen.

An ammunition projectile for a firearm comprising a projectile having a nose and a cap which is designed to slow down sufficiently, when traveling through air so as to be stopped by a bulletproof vest while the projectile still has a precise and reliable trajectory. The projectile (10) has a generally truncated nose (11) and a cylindrical cap (12). The nose (11) is provided with a central, essentially circular flat section (13) which can be made larger or smaller and which has a diameter of between 10 and 50% of the diameter of the projectile at the base of the nose (11) or the cap (12). The lateral face of the truncated nose (11) is provided with five indentations (14) which are disposed symmetrically in relation to axial planes and which are obtained by one of stamping, milling, or some other suitable machining method.

Providing a power supply apparatus for a sliding structure, which can prevent a wiring harness from penetrating into an opening when the sliding structure is opened half, and sound noise when the sliding structure is closed, the power supply apparatus for the sliding structure includes a car body, a sliding door mounted slidably on the car body, the wiring harness wired between the car body and the sliding door, a fixed portion and a limiting member. One end of the wiring harness is fixed at the car body. The other end of the wiring harness is fixed at the fixed portion, which is mounted on the sliding door. The limiting member abuts on a bottom edge of an inner edge of an opening.

A quick connect / wuick disconnect locking structure is arranged in connection with the semi-cylindrical members for locking them to one another with the free edges opposite one another.

The invention relates to a sensor array for detecting travel of a movable member, especially a positioning element that is movable using an actuator. Said sensor array comprises a stationary coil arrangement (18) that is provided with an active coil (18.1) and at least one passive coil (26.1, 26.2) located a distance therefrom. The coil arrangement (18) is connected to a power supply unit (30) and a signal-detecting device (29). The inventive sensor array further comprises an axially movable rod-shaped sensor part (17) that is made of a preferably magnetizable material, is connected to the positioning element which is movable fore and aft in an axial direction, and is provided with at least one short circuit element (23, 23.0). Said at least one short circuit element (23, 23.0) is made of an electrically conducting material having low ohmic resistance, is delimited by a final edge (23.1, 23.2) in the longitudinal direction, respectively, and has a dimension in the direction of movement, which is calculated such that one final edge (23.1, 23.2, 23.3) of the at least one short circuit element (23) is enclosed by the active coil (18.1) in at least one final position (I, II) defined by the predefined length of stroke (h) while another final edge (23.1, 23.2, 23.3) of the at least one short circuit element (23, 23.0) is at least partly embraced by one of the at least one passive coils (26.1, 26.2).

An aerodynamic measurement probe intended to equip an aircraft. The probe comprises a tube intended to face substantially into a flow of air along the aircraft, the tube being open at a first of its ends. The probe further emits an electromagnetic wave directed towards a free zone situated in the extension of the tube on the side of the open end, the electromagnetic wave making it possible to reheat the water likely to be located in the free zone.

A turbine engine component has a substrate, a thermal barrier coating deposited onto the substrate, and a sealing layer of ceramic material on an outer surface of the thermal barrier coating for limiting molten sand penetration.
