51. Equations for the Magnetic Field Produced by One or More Rectangular Loops of Wire in the Same Plane
Series: Journal of Research (NIST JRES)
Topic: Sensors
Published: 7/1/2000
Author: Martin Misakian
Abstract: Beginning with expressions for the vector potential, the equations for calculating the magnetic flux density from up to three rectangular loops of wire in the same plane are derived. The geometry considered is the same as that found in some walk-thr ...

52. A Measurement System for Characterizing the Detection Performance of Metal Detectors: Design and Operation
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 6530
Topic: Sensors
Published: 6/1/2000
Authors: Nicholas G Paulter Jr, Donald R Larson, Jon Robert Pratt
Abstract: A measurement system for evaluating the performance of hand-held (HH) and walk-through (WT) metal detectors is described. These detectors produce time-varying magnetic fields that interact with objects comprised of electrically conductive and/or mag ...

56. Using Chaos to Generate White Noise
Topic: Sensors
Published: 11/15/1999
Author: Richard Lloyd Kautz
Abstract: Numerical simulations reveal that a phase-locked loop can be operated in a chaotic regime to generate a high level of noise which is approximately white over a broad frequency range. Heuristic arguments indicate that the low-frequency power spectrum ...

57. A Capacitance Standard Based on Counting Electrons
Topic: Sensors
Published: 9/1/1999
Authors: Mark W Keller, A P Chen, John M. Martinis, Neil M Zimmerman
Abstract: A capacitance standard based directly on the definition of capacitance was built.

58. Leakage and Counting Errors in a Seven-junction Electron Pump
Topic: Sensors
Published: 9/1/1999
Authors: Richard Lloyd Kautz, Mark W Keller, John M. Martinis
Abstract: Leakage and counting errors are explored experimentally in a well-characterized seven-junction electron pump and compared with predictions of the orthodox theory, including cotunneling.
