Industrial Research has developed an active vibration control system to reduce vibration from headrig bandsaws, that enables thinner saw blades to be used.

A feedback system applies control forces using non-contact electromagnetic guides.

Abruptly collapsing roofs and toppling walls are occupational hazards for firefighters and rescue workers. The day may be approaching when devices called vibration sensors could give early warning to building collapse, significantly reducing risks to firefighters.

In recent years, the term microelectromechanical systems (MEMS) has become synonymous with the reference to such low-cost sensors, generally implying the use of a micro-machined silicon structure as the heart of the sensing element. More recently, however, advances in ceramic processing and production have spawned a new generation of low-cost, low-power piezoelectric accelerometers. These devices rival most MEMS sensors in price, while offering a new range of performance choices for many industrial vibration monitoring applications.
