    Abstract: A time domain reflectometry linear position sensing system having a transmission line with a helically wound inductor and a ground conductor. The transmission line includes a movable member that electrically connects with the ground member and which extends along the inductor from a first end a distance that depends on the position of an object whose position is being determined. A signal generator applies pulses between the first end and the ground conductor and a receiver receives reflections of those pulses. The delays between the applications of pulses and the receptions of reflections depend upon the position of the object. A position determining circuit determines the position of the object based upon the delays, beneficially by using sing-around. Beneficially, a third member extends a predetermined distance along the inductor from a second end. That third member provides a reference delay that can improve the system accuracy.

    Abstract: A device for introduction of an ammonia dopant into a spectrometry system without the use of a delivery system containing ammonia. The delivery device includes an ammonium solid that will, upon the introduction of heat, yield ammonia gas for delivery into the spectrometer system. Use of such an alternative to traditional ammonia dopant systems will yield little or no change in spectrometer readings. The volumetric flow rate of the ammonium is controlled by the use of capillary tubes as the exiting pathway, where the flowrate is determined by the cross sectional area and length of the capillary tube. Delivery of the ammonia is aided by use of a frit or screen to permit only gas to exit.

    Abstract: Resonant decay sensors that determine a parameter based on the decay of acoustic standing waves in a tube. Parameters that can be determined include temperature, pressure, the level of a material in the tube, and the height of a material above an end of the tube. Resonant decay sensors can produce both point level and continuous level sensors. A vibration mount, such as a rubber ring, beneficially isolates an acoustic transducer from the body of the tube.
