Abstract: A catheter device for crossing occlusions includes an elongate body, a central lumen extending within the elongate body from the proximal end to the distal end, a rotatable tip at the distal end of the elongate body, and an OCT imaging sensor. The rotatable tip is configured to rotate relative to the elongate body. The OCT imaging sensor includes an optical fiber coupled with the rotatable tip and configured to rotate therewith. A distal end of the elongate body includes one or more markers configured to occlude the OCT imaging sensor as it rotates. A fixed jog in the elongate body proximal to the distal end of the catheter positions the distal end of the catheter at an angle relative to the region of the catheter proximal to the fixed jog and is aligned with the one or more markers on the elongate body.

Abstract: A refueling system is characterized by the delivery of fuel through a multi-stage telescoping cylinder assembly which uses the fuel as the pressure media for extending and retracting the cylinder assembly. Provision also is made for rotating or pivoting the cylinder assembly about two orthogonal axes which, when combined with telescopic extension and retraction of the cylinder assembly, enables a normally closed nozzle connected to the forward end of the innermost piston cylinder to be positionally directed to the fuel inlet portion of the combat vehicle to be refueled. Another attribute of the system is that when properly seated in the fuel inlet port, the nozzle automatically opens.

Abstract: An industrial process control system in accordance with the present invention includes a plurality of device controllers connected together through a common buss with each device controller connected to an associated controlled device(s) that effect process control. A computer-aided system interface for controlling the overall system includes a visual display device in the form of a multi-color CRT and a graphic input device in the form of a transparent touch-responsive panel that overlies the CRT display screen. Computer generated symbols representing the controlled devices are displayed on the CRT screen to define touch-responsive target areas. When an appropriate target area is touched by a human operator, a signal, such as a command signal, is generated to cause the controlled device whose symbol is displayed in the designated target area to respond, with this response being then indicated by a change in the device symbol being displayed on the screen.
