Passivity Filter for Variable Impedance Control [PDF]
2020 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS), 2020 While impedance control is one of the most commonly used strategies for robot interaction control, variable impedance control is a more recent preoccupation. If designing impedance control with varying parameters allows increasing the system flexibility and dexterity, it is still a challenging issue, as it may result in a loss of passivity of the ...

Parametrically enhanced bandpass filters
IET Microwaves, Antennas & Propagation, 2021 This paper proposes a technique to enhance the quality factor (Q) of a resonator, which can then be used to realise bandpass filters (BPFs) with reduced insertion loss (IL) and improved passband selectivity.

Passive Noise Filtering by Cellular Compartmentalization [PDF]
Cell, 2016 Chemical reactions contain an inherent element of randomness, which presents itself as noise that interferes with cellular processes and communication. Here we discuss the ability of the spatial partitioning of molecular systems to filter and, thus, remove noise, while preserving regulated and predictable differences between single living cells.
