PI positioning stages help reveal secrets of teeth
Tooth decay is often revealed by an X-ray taken in the dentist’s chair. The image taken is relatively coarse and only reveals the presence of the problem, what it doesn’t show is detail about the mechanism that has led to the decay. Understanding the processes that occur during tooth decay and indeed repair involves researchers looking at concentrations of minerals such as Calcium present in the structure. X ray microtomography is now helping researchers at Queen Mary, University of London (QMUL) gain a deeper understanding of these underlying processes by generating high resolution images that can detail mineral concentrations in the tooth. The image generation involves scanning the tooth and X-ray detector with high precision over an extended time period. PI linear and rotary stages, chosen for their precision and long-term reliability, have been successfully employed in this research work for a number of years.
Multi-pedal footswitch/joystick on ophthalmic surgery microscope
Herga Technology designs and supplies hand and foot controls for medical equipment applications. The diverse requirements for this demanding industry calls for single and multi-pedal switch control products that cover contact and non-contact electric switching as well as pressure and vacuum switching technologies. For many medical applications areas, Herga is able to call upon its IEC/UL 60601 approval status to supply what it terms as ‘standard’ products that effectively still offer customers a wide choice of selectable feature options for the actual operating specification of the device as well as its styling and aesthetics. These options extend to switching/sensing parameters, number of switches, mechanical and electrical interfacing, colours, customer logos etc.

Hepcomotion benefits set in stone at Medway Marble
Medway Marble, a specialist in granite worktops and a long-time user of HepcoMotion linear motion products, says it has recently sold a stone-cutting table-type machine featuring HepcoMotion parts for nearly the same value as it was built some 12 years ago. In the years between, the machine has been exposed to an extremely aggressive stone cutting environment – grinding dust turns to an abrasive paste when it mixes with coolant water from the cutting wheel.
