Novel Dental Imaging

Reference Number:1644 Background With recent discoveries in the way that dental disease develops, the desire for the dentist to be able to detect, and subsequently diagnose, early caries has increased significantly. In the case of early lesions the initial loss of mineral from the tooth can frequently be reversed and through the use of good oral...

Combined optical pressure and temperature sensor

Reference Number:1706 Background Over the last decade or so oil has become an increasingly scarce non-renewable source of energy, thus production has necessarily moved towards deeper wells and more unconventional recovery methods. This requires equipment used in the various processes to operate in conditions where both the pressure and temperature...

Reflective Multistable LCD

Reference Number:1653 Background Liquid crystal displays (LCDs) dominate the market for flat panel electronic displays due to their size, low-drive voltage and low-power consumption. They have been used in calculators, watches and simple digital displays since the 1970s, but more recently their use has extended to mobile phones, laptop computers,...
