The measurement accuracy of a magnetic gradiometer relies on magnetometer consistency, accuracy, and assembly technology. traditional methods calibrate error, misalignment the interference field independently. However, after long time work, calibration parameters will inevitably change. Furthermore, it waste lot manpower material resources if is disassembled calibrated step by step. Given above...

Magnetic force microscopy (MFM) is a characterization method used to obtain images of the stray field emanating from surface magnetic samples with high spatial resolution. The MFM signal arises convolution moment distribution tip sample. Therefore, deconvolution sample requires well-defined micromagnetic structure tip. While remains challenging assess, it convenient calibrate tip-equivalent cha...

Over the last decade or so micro-electromechanical system (MEMS) technology has been widely used in many navigation applications such as pedestrians, aircraft, land vehicles and robots, because of its advantages in terms of price, accuracy and size. This paper presents a novel low-cost multisensor hardware platform known as “NAVCON”, which is designed for navigation and control of quad-rotor un...

Semiconductor Research Corporation under contract no 2008-KJ-1871 Abstract—The magnetic field in an electron cyclotron resonance plasma processing system was characterized using IEEE standard measurement practices. We discuss methods for a low-cost Hall-effect sensor array construction, calibration, and measurement collection to meet or exceed available standards. Utilizing standard measurement...

A precision generating and measurement system of AC magnetic flux density was developed by using a linear low-frequency AC magnetic field converter, a quartz Helmholtz coil, a voltage comparator, a multimeter, a standard resistor, and a computer with a program for automatic measurement. The expanded uncertainty (k=2) of the calibration system is less than 0.2 % over the frequency range of 1 Hz ...

In this paper, we address the calibration of a family magnetic manipulation systems composed several coils that are moved around by serial robot manipulators. We show in paper whole system ultimately results calibrating manipulator and coil separately up to an unknown rigid transformation. For coil, propose use model has not been used so far literature; control-oriented which is sufficiently ac...

Giant magnetoresistive biosensors possess great potential in biomedical applications for quantitatively detecting magnetically tagged biomolecules. Magnetic sensing does not suffer from the high background levels found in optical sensing modalities such as the enzyme linked immunosorbent assay translating into a technology with higher sensitivity. However, to reveal the full potential of these ...
