Via Resonance Amplitude Control
2021 International Conference on Electronics Packaging (ICEP), 2021PCB via stub causes resonance whose frequency is dependent on via stub length. Amplitude of resonance is determined by via stub structure and return paths for the signal. Amplitude of resonance can be controlled by changing the impedance of the via stub.

Dynamically controlled dielectrophoresis using resonant tuning
ELECTROPHORESIS, 2021AbstractElectrically polarizable micro‐ and nanoparticles and droplets can be trapped using the gradient electric field of electrodes. But the spatial profile of the resultant dielectrophoretic force is fixed once the electrode structure is defined. To change the force profile, entire complex lab‐on‐a‐chip systems must be re‐fabricated with modified ...

A hearing aid having a microphone, an amplifier and a receiver for delivering the amplified sound to a user's ear, in which an adjustable resonant peak control is used to shift the frequency response of the amplifier to a lower frequency range in order to reduce feedback without substantial reduction in high frequency amplification or saturation levels.

Resonant Electrical Control Systems
Journal of the Aeronautical Sciences, 1943The electrical phase shift between the current and the applied voltage in a series-resonant circuit as the resonant-circuit tuning is varied is used as the basis of operation for resonant electrical control systems. The author discusses application of such systems to aircraft and industrial problems, and to single and multiphase radio control.

Resonant nonlinear control circuits
Electrical Engineering, 1938The resonant type of nonlinear circuit containing a resistance, a condenser, and a saturable-core reactor is finding a number of applications in the various engineering fields,1 and an analytical treatment has here been developed to add to the understanding of the behavior of such circuits.

Resonant lines for frequency control
Electrical Engineering, 1935Vacuum tube oscillators for radio frequency signals above 25 megacycles may be controlled with a high degree of precision by resonant lines, and at lower frequencies may be used to obtain a larger power output than is obtainable from crystal oscillators.

A resonant work performing apparatus is disclosed which includes a resonant system which is vibratory in resonance at an unloaded resonant frequency. The resonant system has a vibratory input at a frequency near the resonant frequency, and a vibratory output responsive to vibrations at the input.

Wide-Range Frequency Control in Magnetoacoustic Resonator
IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control, 2020Acoustic resonators based on antiferromagnetic crystals of "easy plane" type, like α -Fe2O3 or FeBO3, are of interest for applications in magnetoacoustic sensors of electrical and mechanical values because of high sensitivity of their resonance frequency to variations of external magnetic field or mechanical stress. One of the requirements for magnetic
