The phrase "active barrier" is correct and usable in written English.
It can be used in contexts related to security, technology, or physical barriers that are designed to actively prevent access or intrusion.
Example: "The active barrier system was implemented to enhance security at the facility, ensuring that unauthorized personnel could not enter."
Alternatives: "dynamic barrier" or "proactive barrier".
Its unique active barrier design allows to expel disinfectant on the sharp when it breaches, the viral load transmitted through the glove is therefore reduced.
Skin is the largest organ in human body and works as biologically active barrier to provide critical preservation of body homeostasis.
The development of double layer silica coating on SiC particles is demonstrated as a method to create an active barrier which improves wetting and reduces interfacial damage during the manufacturing by a liquid route of aluminium matrix composite reinforced with SiC particles.
The room is modeled with the image method as a rectangular enclosure with a stationary point source; the active barrier is set up by an array of loudspeakers and error microphones and is meant to minimize the squared sound pressure on a wall with the use of a decentralized control.
In some conditions, SiC particles were coated with a sol gel silica coating, which acts as an active barrier enhancing the wettability of the reinforcement by molten aluminium reducing the porosity of the composite coatings and inhibiting the formation of aluminium carbide.
In the investigated configuration, the surface attenuation and the diagonal control stability are mainly driven by the distance between the loudspeakers and the error microphones and by the loudspeakers directivity; minor effects are due to the distance between the error microphones and the wall, by the wall reflectivity and by the active barrier grid meshing.
The barrier detection time is shown to scale linearly in terms of the number of active barriers in the system.
Special emphasis is given to the role of membranes as active barriers for enhanced selectivity and sensitivity of analytical procedures.
There seems to be a tendency towards using active barriers which are capable of removing certain contaminants within MSW leachate, although they are usually designed on a contaminant specific basis.
Active barriers with triggering devices are therefore developed to try and meet this need.
For effective operation active barriers detect the arrival of the flame front and then need to effectively disperse the inert materials for suppression.
