  • Patent number: 7279903
    Abstract: A non metallic flow through electrodeless conductivity sensor is provided with a conduit having primary and secondary process fluid flow paths to form a fluid loop. At least one drive and one sense toroid surround the conduit on the fluid loop. Voltage supplied to the drive toroid induces a current in the sense toroid via the fluid loop to eliminate any need for metallic electrodes in contact with the process fluid. At least one additional drive and/or sense toroid is disposed on the fluid loop to enhance induction. Optionally one or more sense coils are disposed about the conduit outside of the fluid loop to cancel out stray electrical noise. An optional conductor disposed along the conduit detects any fluid leakage through changes in resistance thereof. A temperature detector is supported within an electrically non-conductive holder extending into the fluid flow path, so that the detector is free from physical contact with the fluid.

  • Patent number: 7002361
    Abstract: An apparatus for measuring the thickness of thin-film cause electron beams of first and second energies to strike thin-film to be measured that is formed on a silicon substrate, and measures the first substrate current value of current flowing in the substrate when it is struck by an electron beam of a first energy and the second substrate current value of current flowing in the substrate when it is struck by an electron beam of a second energy. The thin-film measuring apparatus obtains reference data indicating a relationship between the film thickness and a reference function having as variables the substrate current for the case of an electron beam of the first energy striking a standard sample and the substrate current for the case of an electron beam of the second energy striking the standard sample, and calculates the thickness of the thin-film under measurement based on the first and second substrate current values, giving consideration to the reference data.

  • Patent number: 6998853
    Abstract: A LAN tester has display and remote units each having a connector jack attached to an adapter board for connection to the plug of a patch cord. Both the display and remote units have circuits which are capable of measuring the phase between a drive signal voltage and the corresponding coupled or reflected signal due to the drive signal. Scattering parameters for the mated connector pairs and the patch cord itself are measured during a field calibration. A computer in one or both of the tester units stores the measured scattering parameters and uses the scattering parameters to move the reference plane to any desired location along the patch cord. The length of the patch cord can be determined through the use of phase by measuring the frequency difference between adjacent maxima of a plot of input impedance versus frequency.
