摘要： A highly selective, sensitive, fast detection system and method are disclosed for detecting vapors of specific compounds in air. Vapors emanating from compounds such as explosives, or stripped from surfaces using heat and suction from a hand-held sample gun, are collected on surfaces coated with gas chromatograph (GC) material which trap explosives vapors but repel nitric oxide, then are desorbed and concentrated in one or more cold spot concentrators. A high speed gas chromatrograph (GC) separates the vapors, after which specific vapors are decomposed in two pyrolyzers arranged in parallel and the resulting nitric oxide is detected. A low temperature pyrolyzer with silver produces NO from nitramines or nitrite esters; a high temperature pyrolyzer decomposes all explosives vapors to permit detection of the remaining explosives. Also disclosed is a series arrangement of pyrolyzers and gas chromatographs and an NO detector to time-shift detection of certain vapors and facilitate very fast GC analyses. The use of hydrogen as a carrier gas, plus unique collectors and concentrators, high speed heaters, NO detectors, and very fast, temperature-programmable GC's enhance selectivity, sensitivity and speed of detection.

摘要： An improved catheter and catheter system for long term implantation in a patient through a percutaneous access device are provided. The improved catheter has a loop in an external lead portion of the catheter which reduces bending, kinking, and cracking of the catheter and which reduces stress on the catheter and on the percutaneous access device as well. The system employs multiple catheters, each catheter having a loop to reduce stress. Each of the catheters of the system may have a single lumen or multiple lumens. A method of relieving stress at an external lead portion of a single or multi-lumen catheter is also provided.

摘要： An implement position control device including a central processing unit (6) coupled to an ultrasonic transducer (17) and receiver/amplifier (20) adapted to calculate the distance to a reference target (12 and a relatively more distant surface (9). Control pulses are initiated by the CPU (6) to manipulate a solenoid (25) by means of a valve driver (24) in response to the calculated distance measurements. An autotune task (26) causes a series of precise pulses to manipulate the solenoid, thereby permitting calculation of the transfer function (52) defining the relationship between pulse width and implement position.

摘要： Disclosed are a method and apparatus for high speed, selective detection of vapors of specific compounds, particularly nitrogen-containing compounds, utilizing a bypass branch and high speed gas chromatography for improved selectivity and sensitivity of detection. A system with two gas chromatographs (GC's) alternating in series with two pyrolyzers provides two time intervals of detection in a downstream detector, with the second time interval containing signals delayed and further separated relative to signals from the first time interval. The bypass branch, in diverting a portion of the flow of gas samples from passage through the second gas chromatograph and second pyrolyzer, avoids interferences in the first time interval of detection from non-GC-retained compounds decomposed in the second pyrolyzer. Also disclosed is an arrangement for rapid, precise heating of vapor concentrator tubes in which vapors are rapidly focussed and then injected into a GC, and for rapid, precise heating of the GC's.
