  • Eddy Current Profiles Parts
    potentiometer or a linear variable differential transformer (LVDT).
  • Low-Voltage, Low-Power CMOS Current Conveyors
    Low-Voltage, Low-Power CMOS Current Conveyors. Providing a brief history of the first and second generation CC, this text goes on to describe LV LP CCII implementations, their evolution towards differential and generalized topologies, and new possible CCII applications in some basic analog
  • Ground-fault interrupters
    as an example of how these switches operate. Phase and neutral power conductors pass through a toroidal (differential) current transformer. Under normal conditions, the vector sum of the currents in the live and neutral conductors will equal zero. In an unhealthy circuit a residual current flows
  • AN-0300 - High Voltage Op-Amp Application Using Opto-Couplers
    Op-Amp, but in this case, differential output currents are optically. coupled to a pair of optocoupler cells in series across high voltage rails.
  • Introduction
    testing as well as the motion of charged particles in electric fields. Multiphysics applications include coupled stress, electromagnetic and thermal analysis. Students taking a course in electromagnetic theory usually concentrate mostly on analytical techniques, e.g., solving differential equations
  • Magnetic Sensing
    in salt spray or sand and dust environments, and under differential pressures up to 20,000 psi. Eddy-current sensors detect ferrous and nonferrous metals. A high-frequency magnetic field induces eddy currents in metal targets. The eddy currents generally change the
  • Automatic Accelerometer Calibration System (.pdf)
    or differential, AC or DC coupled, isolated or grounded.
  • Driving Diode Lasers
    rises steeply with increasing diode operating current. The correlation between the optical output power and the diode current is linear up to the maximum power, called differential efficiency (Figure 1). One crucial figure often overlooked in handling diode lasers is the influence of temperature
  • NEC Corporation High-resolution Measurement by a High-T Superconductor Sampler
    Abstract-We measured a signal current waveform by using a. high-Ti superconductor (HTS) sampler with a 1-ps delay be. tween every sampling point. The maximum time differential. obtained in the measured waveform was 12 jiA]ps with 2.5-jiA. current seusitiiitv at 25 K. This result guarantees
  • Design and Development of Medical Electronic Instrumentation
    for this chapter include chloriding silver. electrodes, high-impedance electrode buffer array, pasteless bioelectrode, single-ended. electrocardiographic (ECG) amplifier array, body potential driver, differential biopotential. amplifier, instrumentation-amplifier biopotential amplifier
