摘要:
Methods and apparatus for static charge neutralization in variable pressure environments are disclosed. In particular, barrier discharge ionization apparatus may include a hollow dielectric channel disposed within a variable pressure environment and may have at least one open end, a reference emitter disposed on the outer surface of the channel, and a high voltage electrode disposed within the channel. The high voltage electrode may present a high intensity electric field to the reference emitter through the dielectric channel in response to the provision of a variable-waveform signal dictated by conditions in the variable pressure environment. This results in the generation of a plasma region with electrically balanced charge carriers within the variable pressure environment due to barrier discharge occurring at the interface of the reference emitter and the outer surface of the dielectric channel. The disclosed apparatus are compatible with either radio frequency or micro-pulse voltage power supplies.

A multi-sectional linear ionizing bar with at least four elements is disclosed. First, disclosed bars may include at least one ionization cell with at least one axis-defining linear ion emitter for establishing an ion cloud along the length thereof. Second, disclosed bars may include at least one reference electrode. Third, disclosed bars may include a manifold for receiving gas or air from a source and for delivering same past the linear emitter(s) such that substantially none of the gas/air flows into the ion cloud. Fourth, disclosed bars may include means for receiving the ionizing voltage and for delivering same to the linear emitter(s) to thereby establish the ion cloud. In this way, disclosed ionizing bars may transportions from the plasma region toward a charge neutralization target without inducing substantial vibration of the linear emitter and without substantial contaminants from the gas/air flow reaching the linear emitter.

An in-flight refueling method may include deploying a fueling hose from a refueling aircraft. The fueling hose may have a drogue. The deployment of the fueling hose may include extending the drogue using a telescoping arm having a ring. The deployment of the fueling hose may also include passing the fueling hose through the ring to deploy the fueling hose. The in-flight refueling method may further include retrieving the fueling hose by drawing the drogue into a wire pitch mounted on the ring and collapsing the drogue in response to drawing the drogue into the wire pitch.
摘要:
An in-flight refueling device includes an arm, ring and actuator. The arm has a proximate end and a distal end. The ring is secured to the distal end and is configured to releasably secure a drogue for a refueling hose. The actuator is secured to the proximate end and is configured to extend the arm a predetermined distance.

摘要:
Method and apparatus for the extracorporeal treatment of blood by utilizing a peripherally inserted dual lumen catheter assembly for the continuous removal and return of blood for renal replacement treatment, in particularly, treatment of congestive heart failure and fluid overload by ultrafiltration. A catheter is inserted in a peripheral vein and maneuvered upward through the vascular system to access the reservoir of blood in the large or great veins for continuous blood withdrawal and treatment. Air-tight connectors are incorporated in the catheter assembly to overcome the untoward effects of negative pressure in blood withdrawal.
摘要:
An optical system using ambient light. The system includes a screen to be illuminated, an internal light source and an external light collector to collect ambient light to illuminate the screen. A switch may be used to activate the internal light source, providing internal light to be combined with the ambient light to illuminate the screen. A light sensor may also be used to detect the level of light presented to the screen, with or without a controller to automatically control the process of providing illumination to the screen.
