Abstract: A method and system for determining atmospheric disturbances or turbulence is disclosed. The system includes a plurality of sensor arrays, including at least one sensor element, distributed in a predetermined manner. Each of the sensor elements is in communication with a corresponding receiving system that is operable to receive and process energy received from the aircraft. A determination is then made regarding air turbulence by determining a rate of change of signal phase among selected sets of signals received at the receiving systems. A turbulence map is then determined from the determined rate of change of the phase and the angle of the received signal. When the rate of phase change exceeds known levels an indication of turbulence is made.

Abstract: A single lumen monorail intra-aortic balloon catheter and guide wire system. The catheter and guide wire being advanced through a patient's vasculature as a unit. The guide wire comprising a tip guide section and a pull section configured so as to minimize bleeding at the insertion site.

Abstract: A balloon catheter having a micromanometer connected to the catheter and also a fluid-filled transducer system for adjusting micromanometer pressure measurements.

Abstract: A medication delivery pen having a repeat-dose feature that limits motion of the dose control mechanism using an adjustable repeat-dose stop on the dose knob. In addition, the medication delivery pen also provides the user a simple mechanism for setting and correcting the dose and a drive mechanism that makes the dispensing operation as easy as possible requiring as little force as necessary.

Abstract: A medication delivery pen having a repeat-dose feature that is performed by using a pull-push operation. In particular, the medication delivery pen includes means for whether the medication delivery pen is armed and a variety of novel drive mechanisms. In addition, the medication delivery pen also includes a priming control mechanism that allows the user to easily prime medication delivery pen prior to arming the pen.

Abstract: A medication delivery pen having a vial retainer with a side opening have flexible snap wings that spread to receive and retain a standard or threaded vial within the vial retainer. The vial retainer also includes an improved means of attaching the vial retainer to a pen injector body, using a cam and cam follower design together with a ratcheting mechanism to prevent removal of the vial from the medication delivery pen. Alternatively, a release mechanism could be used so that the vial may be removed from the medication delivery pen. In addition, the vial retainer includes an opening for receiving the vial defined by a pair of flexible snap wings.

Abstract: A medication cartridge for use with a medication delivery pen having a cartridge body with threads at its distal end for receiving a pen-needle. The threads are either integrally molded in the cartridge or on the outer surface of a cap used to retain a septum on the distal end of the cartridge body. The cartridge body of the medication cartridge also includes threads or a snap-ring at its proximal end for attaching the medication cartridge directly to a pen body housing of the medication delivery pen without the need for a medication cartridge holder.

Abstract: A method and apparatus for accumulation of hyperpolarized .sup.129 Xe is disclosed. The method and apparatus of the invention enable the continuous or episodic accumulation of flowing hyperpolarized .sup.129 Xe in frozen form. The method also permits the accumulation of hyperpolarized .sup.129 Xe to the substantial exclusion of other gases, thereby enabling the purification of hyperpolarized .sup.129 Xe. The invention further includes .sup.129 Xe accumulation means which is integrated with .sup.129 Xe hyperpolarization means in a continuous or pulsed flow arrangement. The method and apparatus enable large scale production, storage, and usage of hyperpolarized .sup.129 Xe for numerous purposes, including imaging of human and animal subjects through magnetic resonance imaging (MRI) techniques.

Abstract: A method and apparatus for hyperpolarization of flowing noble gases is disclosed, including means for hyperpolarization of noble gases in a continuous flow arrangement. Noble gases such as xenon-129 and helium-3 can be hyperpolarized using the disclosed method and apparatus. Preferably, the noble gas is hyperpolarized via spin exchange between atoms of the noble gas and an alkali metal such as rubidium. Also, a method and apparatus for accumulation and/or storage of hyperpolarized noble gases in a continuous flow arrangement is provided. The method and apparatus enable large scale production, storage, and usage of hyperpolarized noble gases for numerous purposes, including imaging of human and animal subjects through magnetic resonance imaging (MRI) techniques.
