Abstract: A catheter for use in magnetic resonance imaging includes a catheter shaft having a proximal end and a distal end. A flexible lumen is supported on the distal end of the shaft, and the flexible lumen is configured to be expanded and contracted using a fluid introduced via the proximal end of the catheter shaft. A magnetic resonance coil formed on the flexible lumen such that the magnetic resonance coil may expand and contract with the flexible lumen. The magnetic resonance coil is coupled to an external match and tune circuit via magnetic resonance imaging device. The balloon coil includes nested bazooka or sleeve baluns along the length of the cable to minimize common mode currents on the outer surface of the cable to prevent high current hot spots that cause heating of the cable.

Abstract: A flight management system and method is provided that determines segment sequencing during entry into holding patterns and the holding patterns themselves. The flight management system and method monitors the aircraft's progress along the active segment of the flight plan to determine what is the appropriate next segment and when to switch control from the active segment to the next segment. The flight management system can determine the appropriate next segment for the aircraft based on a variety of factors. These factors including aircraft position relative to a wayline, the existence of any cross track error, and whether or not the projected aircraft track will intersect an active segment. Preferably, the flight management system evaluates the aircraft state parameters at each wayline crossing to determine which segment is appropriate to control to next. If none of the segments are appropriate, then the control is defaulted to a default segment.

Abstract: A door security system includes a lock that is released by an electronic control unit carried on the door and activated by radiation from an r.f. oscillator in a user's key unit. The key unit, provided on a finger ring, includes one or more photovoltaic devices that convert light energy received from a lamp on the door to electrical power for the r.f. oscillator. The r.f. emission may be binary-code modulated and the control unit then includes an appropriate modulation-code detector. The door unit may also include a light-source that emits coded pulses of infra-red light and then the key unit includes a circuit to detect whether the infra-red light received is of the appropriate code-format as a condition for activation of the r.f. oscillator.
