Some people cannot use stairwells because of physical disabilities, and for these people fire evacuation is a serious problem. A potential solution to this problem is the use of elevators for fire evacuation. A joint project of the U. S. National Institute

Milliwatt mixer for small fluid samples

February 1, 1991
Author(s)
Robert F. Berg, Nicholas P. De Luca
Mixing without excessive heating is sometimes needed for temperature-sensitive fluids. We modified an inexpensive low-frequency electronic filter based on a mechanical resonator to produce a compact (16 mm) and low-power (l-3 mW) mixer for low viscosity
