Multi-domain active sound control and noise shielding [PDF]

, 2011
This paper describes an active sound control methodology based on difference potentials. The main feature of this methodology is its ability to automatically preserve “wanted” sound within a domain while canceling “unwanted” noise from outside the domain.

Time-dependent evaluation of machine and shielding activation for medical accelerator systems: Self-consistent numerical evaluation of concrete shielding activation for proton therapy systems

, 2023
Next-generation proton therapy centres are evolving towards compact designs to reduce construction and decommissioning costs. These centres typically combine clinical treatments with research programs, leading to higher beam currents and longer irradiation times than in clinical conditions, thus producing a more significant number of secondary ...

On-scalp MEG system utilizing an actively shielded array of optically-pumped magnetometers

NeuroImage, 2018
AbstractThe spatial resolution of magnetoencephalography (MEG) can be increased from that of conventional SQUID-based systems by employing on-scalp sensor arrays of e.g. optically-pumped magnetometers (OPMs). However, OPMs reach sufficient sensitivity for neuromagnetic measurements only when operated in a very low absolute magnetic field of few ...
