The National Endowment for Science, Technology & the Arts, NESTA, in the UK has awarded an engineer, Giovanni Bisutti, £75,000 to develop a system for pneumatic tools, such as jack hammers, to reduce the effects of vibration on the operators. ‘White finger’ is caused by excessively vibrating tools that cause damage to the hands of the tool operators. The new system uses a water jacket shrouded around the tool that is used to increase the mass of the tool by 15kg. Water is transfered into the tool when in operation and is removed within 3 seconds when the tool is to be moved.

JMC Products has developed a DC motor for fans that is significantly quieter than conventional motors. In a conventional fan motor a square wave switching voltage is applied to the stator that generates torque ripples and vibrates the entire structure which makes a ticking noise. JMC have reduced this noise by changing the switching frequency to 25kHz, above the range of human hearing.
