A Method for Joining Polymers and Metals or Polymers and Ceramics
A recently developed laser fusion technique allows polymers to be attached to metals and ceramics in short cycle times. The process and its capabilities are reviewed together with its growing range of applications.

Developments in Multicavity Hot Runner Tooling
Technological developments in specific areas of multicavity hot runner systems are improving quality control and repeatability and reducing cycle times. Advances such as closed loop filling control of multicavity moulds within the mould itself, servo-actuated valve gates and synchronised valve stems are discussed.

Laser Micro Machining of Medical Devices
Excimer and increasingly ultra-short-pulsed lasers are important tools in the creation of microstructures and nanostructures. Capabilities of the latest systems are described, which include drilling 30-µm diameter holes in 50 to 100 µm thick metal foils and subsurface engraving of transparent materials.

Standardising Analogue Front End Design for Ultrasound Imaging Systems
The standardisation of analogue front end products is allowing the development of portable ultrasound devices that provide enhanced image quality while minimising power consumption. The design opportunities associated with the use of these products are described.
