摘要： A single housing with a non-ferromagnetic piezo-driven flexure has primary and secondary coil forms of different diameters, one coaxially inside the other, integrated in the flexure. The cylinders defining the planes of the primary and secondaries do not spatially overlap. The secondary coil forms may be wound in opposite directions and wired to provide a transformer device. Movement of the primary relative to the secondaries in the direction of the central axis of the coils can be differentially detected with high precision.

摘要： A digital system for controlling the quality factor in a resonant device. The resonant device can be a a device that includes a cantilever within its system, such as an atomic force microscope. The quality factor can be digitally controlled to avoid noise effect in the analog components. A direct digital synthesizer implemented in a way that provides access to the output of the phase accumulator. That output is a number which usually drives a lookup table to produce a cosine or sine output wave. The output wave is created, but the number is also adjusted to form a second number that drives a second lookup table to create an adjustment factor to adjust the output from the cosine table. The adjusted digital signal than drives a DA converter which produces an output drive for the cantilever.

摘要： A controller for cantilever-based instruments, including atomic force microscopes, molecular force probe instruments, high-resolution profilometers and chemical or biological sensing probes. The controller samples the output of the photo-detector commonly used to detect cantilever deflection in these instruments with a very fast analog/digital converter (ADC). The resulting digitized representation of the output signal is then processed with field programmable gate arrays and digital signal processors without making use of analog electronics. Analog signal processing is inherently noisy while digital calculations are inherently “perfect” in that they do not add any random noise to the measured signal. Processing by field programmable gate arrays and digital signal processors maximizes the flexibility of the controller because it can be varied through programming means, without modification of the controller hardware.

摘要： A position sensor has a moving coil part that is formed from a first coil form formed of a non ferromagnetic material, and a second coil that also has its form made of non-ferromagnetic material. The coil forms can be formed of non ferromagnetic adhesive. One of the coils moves relative to the other. The stationary coil part sufficiently close to said moving coil part such that magnetic flux from said moving coil part is induced into said stationary coil part. A primary coil is driven with a voltage. The operation senses voltages induced into a plurality of secondary coils, from movement of the primary coil relative to the secondary coils. The sensing can be done using a differential amplifier.
