A new low profile rotary stage leverages Piezo Ceramic Linear Motor (PCLM) technology for use in handling 300-mm silicon wafers for semiconductor processing. With a profile height of only 32 mm, the PLR-300 allows for a minimal working stack-up height when used with other stages--such as mounted atop and straddling a linear stage. This is very beneficial for minimizing causes of abbe error. Powered by two diagonally opposed PCLMs, the PLR-300 is said to provide superior drive balance and intrinsic smoothness. The PCLM also does not generate heat during operation. The stage is non-magnetic as well and compatible with clean room standards. Angular resolution is ±0.0005 degrees with a positioning accuracy of ±2 microns. Anorad, Product Code 4215.
During a teardown of the iPad Air and Microsoft Surface Pro 3 at the Medical Design & Manufacturing Show in Schaumburg, Ill., an engineer showed this "inflammatory" video about the dangers of maliciously mishandling lithium-ion batteries.
The Window Watcher stops the burglar before he does damage or enters the house. House alarm service companies set off alarms and call the service only after the burglar has damaged and entered the house.
