Granted: 2001-07-03
Abstract: An automated test system (10) makes voltage and resistance measurements. A breakout cable (34) is connected between the vehicle electronic control module (30) and the vehicle sensors and controls (32). Resistance measurements are made between a selected pair of connector pins of the breakout cable (34) by connecting a current loop (50) which includes a power supply (56) and a known resistance (R1, R2) through a first multiplexing circuit (70, 72) to the selected pair of pins. A voltage measuring circuit (52) measures voltage across the known resistance (R1, R2) and between the pair of pins. The voltage measuring circuit (52) includes a second multiplexing circuit (82, 84) and a voltmeter (86, 88, 90, 92). The second multiplexing circuit (82, 84) receives inputs from the various pins, as well as from opposite sides of the known resistance (R1, R2) in the current loop (50).      The second multiplexing circuit (82, 84) provides its output to the voltmeter (86, 88, 90, 92) for measurement. By measuring the voltage across the known resistance (R1, R2), and the voltage between the selected pair of pins, the resistance between the two pins can be derived.

Granted: 2004-01-20
Abstract: A method of detecting a target moiety comprising the steps of (a) providing an antibody (37) specific to the target, (b) satu-rating the antibody's (37's) binding sites with a labelled form of the target (39), (c) flowing a liquid containing the target past the antibody (37), (d) allowing the target to displace the labelled antigen (39), and (e) detecting the displaced, labelled antigen (39).   The invention is accomplished by a flow immunosensor: a flowing liquid moves a sample through the immunosensor; a receiving means (13) introduces the sample to the liquid; a flow control means (21, 23) controls the liquid's movement through the immu-nosensor; and exchanger (35) brings the sample into contact with labelled antigens of the target so that any target present dis-places the labelled antigen (39); a detection apparatus (41, 41a) detects any labelled antigen (39) that is released; and a disposal means (45) disposes of or collects the waste coming from the detection apparatus (41, 41a).

Title: Method and apparatus for locating stratification in production fluid in a well
Inventor: GADEKEN LARRY LEE
IPC: E21B47/10
Filed: 1993-02-25
Granted: 1997-12-09
Abstract: There is described a system for determining the existence of stratified flow in the gas phase of well  fluids  produced  in  a  cased well  borehole  and flowing upwardly through a metal casing. The system includes a source of relatively low energy gamma rays, the energy thereof being chosen such that there is a small probability that a gamma ray from this source could penetrate a metal casing and be scattered back through  the  metal  casing  by  material  outside  the casing.  The system should be capable of collimating gamma rays from the source of low energy gamma rays selectively along an azimuthal direction with respect to the axis of the well casing and of generating a signal indicative of the azimuthal direction. Also provided are a scintillation detector of gamma radiation and a cooperative shielding device for preventing direct irradiation of the detector by the source while allowing the placement of the detector in close proximity to the source to allow detection of gamma rays emitted by the source and scattered by materials inside the metal casing. The system should count gamma rays detected by the detector and store count rate signals indicative  thereof.   The  count  rate  signals  are processed according to a predetermined relationship to derive  a measurement  signal  indicative  of  the  gas holdup phase of well  fluid in the vicinity of  the source.  Finally the gas holdup signal is displayed as a function  of  the  azimuthal  signal  to  provide  an indication of stratified fluid flow.

Abstract: Processes are disclosed in which cemented carbide parts, having a wide range of initial carbon levels, and a wide range of sizes, can be carburized to a critical carbon level, and then slow cooled at various rates, to yield stratified enriched zones in the near-surface region of said parts. The enriched zones are characterized by the cobalt content decreasing, and the microhardness increasing, continuously through the enriched zones, and approaching values characteristic of the interior.      The combination of stratified enriched zones in the near surface region and the 6% binder interior provide the toughness and deformation resistance required for heavy roughing applications.      A wide variety of cemented carbides, having different compositions and WC grain sizes, can also be carburized and slow cooled using the same techniques to yield stratified binder enriched zones having the same hardness profiles and cobalt content profiles as described above.
