A dissipator is a device mounted among some sections of a building to reduce strains during an earthquake by slowing down the shaking of the building. During an earthquake, the sections of the building are subjected to movements which are relative to each other (for instance, the relative movement between two different floors). When the structures oscillate, the dissipator devices, some of which are similar to pistons, slow down the vibration by dissipating viscous or friction energy, thus increasing the equivalent viscous coefficient and then reducing the strains on the structure itself.

The suit’s outer dissipator layer glowed cherry red as it radiated away the excess heat, and wisps of smoke rose from around his feet.

Either it had been smuggled into the counting room somehow, or-more likely an access hole just big enough for the device had been drilled through the wall, followed by the explosive charge itself when the dissipator had been activated to soak up the noise.
Such was her force of drive that, streamlined to the ultimate degree although she was, she had special wall-shields, and special dissipators to radiate into space the heat of friction of the medium through which she tore so madly.
