摘要:
An irrigated ablation catheter includes a tip electrode with a thin shell and a plug, defining a plenum chamber. The tip electrode has an inlet of a predetermined size and noncircular shape, and a predetermined number of outlet fluid ports having a predetermined diameter shell wall. The tip electrode thus considers a diffusion ratio of total fluid output area to fluid input area, and a fluid port ratio, and considers a fluid inlet aspect ratio where the fluid inlet has a noncircular radial cross-section. The plenum chamber has a narrow proximal portion opening to a wider distal portion so that fluid pressure decreases while fluid velocity increases thereby increasing turbulence which decreases momentum for a more uniform distribution of fluid in the tip electrode. Extending distally from the plug is a baffle member shaped to diffuse fluid entering the tip electrode and to house an electromagnetic position sensor.

An irrigated ablation catheter includes a tip electrode with a thin shell and a plug to provide a plenum chamber. The tip electrode has an inlet of a predetermined size and noncircular shape, and outlets in the form of fluid ports formed in the thin shell wall. The plurality of the fluid ports is predetermined, as is their diameter. The tip electrode thus considers a diffusion ratio of total fluid output area to fluid input area, and a fluid port ratio. The tip electrode also considers a fluid inlet aspect ratio where the fluid inlet has a noncircular (for example, oval or elliptical) radial cross-section. The plenum chamber has a narrow proximal portion opening to a wider distal portion so that fluid pressure decreases while fluid velocity increases with the desired effect of increased turbulence which decreases momentum for a more uniform distribution of fluid in the tip electrode. Extending distally from the plug is a baffle member shaped to diffuse fluid entering the tip electrode and to house an electromagnetic position sensor.

摘要:
A computer-implemented method and system for simulating a mock press conference for fantasy sports. The method includes presenting a plurality of topics and corresponding questions to a user. The questions are pre-loaded and recorded by a reporter representing a media outlet. The method also includes allowing the user to select a topic and a question. Further, the method includes recording the user's response to the question within a pre-defined time period to develop a corresponding Mock Press Conference video. Furthermore, the method includes processing the Mock Press Conference video once the user successfully completes responding to the question. Moreover, the method includes synchronizing the Mock Press Conference video with the question for automatic playback to simulate a real-life press conference broadcast with media flashes.

A head restraint assembly adapted for inwardly rotating between a substantially upright use position and a relatively retracted storage position is disclosed. According to one exemplary embodiment, the head restraint assembly is configured for use with a vehicle seat having a collapsible seat back for providing improved clearance as the seat back moves between a use position and a storage position. The head restraint assembly generally includes a support member having a first portion adapted for pivotally coupling to the seat back and a second portion that outwardly extends through an aperture defined by a top surface of the seat back for supporting a head supporting cushion. The first portion of the support member has a substantially curvilinear profile for allowing the required size of the aperture in the top surface of the seat back to be minimized in a longitudinal direction relative to the seat back.

An adjustable swivel base assembly and track for swivel mounting fishing boat downrigger or planar board masts, including a planar mounting base plate, a pair of stationary riser supports on the base plate, and a planar bottom bearing plate stationarily supported on the upper ends of the supports. Vertically spaced planar bottom and top bearings are stationarily affixed to the bearing plate and a planar swivel top plate is supported on and sandwiched slidably between the bearings, and is adapted to carry and swivel the mast load. An indexable locking system selectively locks the swivel plate in any one of a plurality of angularly spaced positions. A track is mounted on a fishing boat and has side edge flanges with mutually facing in-turned lips that overlap opposite side edges of the base plate when slidably and releasably mounted in the track.

There is disclosed an electrified wall panel system having a power distribution server locatable within a wall panel unit. The power distribution server has four receptacle module ports oriented in an H-shaped configuration in which a first receptacle port on a first side of the wall panel unit opens toward a first end of the wall panel unit, a second receptacle port on the first side of the wall panel unit opens toward a second end of the wall panel unit, a third receptacle port on a second side of the wall panel unit opens toward the first end of the wall panel unit, and fourth receptacle port on the second side of the wall panel unit opens toward the second end of the wall panel unit. First and second harnesses are each electrically connected at first ends thereof to the power distribution server, extend to opposite ends of the wall panel unit, and include connector ports on the second ends thereof for providing electrical interconnection of adjacent wall panel units. There is also disclosed an electrified wall panel system with wall panel connector interchangeably usable with the interconnection of two, three, and four wall panel units. The connector includes a hook member for connecting together adjacent vertical members of frames of adjacent wall panel units at a lower portion thereof and a draw nut for connecting together adjacent vertical members of frames of adjacent wall panel units at an upper portion thereof by vertical displacement thereof.

Disclosed are toner compositions which comprise a toner particle having cleaning and lubricating agents added externally thereto. The cleaning and lubricating agents improve copy quality and extend the developer lifetime as they are electrically compatible with the toner particles over the duration of the developer lifetime. The external lubricating additive comprises a modified wax component having a relatively small percentage of a charge enhancing additive dissolved in a low molecular weight wax material. Optionally, the external additive may comprise amorphous silica particles and magnetite particles.
