CA40 rotatable-head proximity sensor is unaffected by strong electromagnetic ac or dc fields, such as resistance-welding operations. Using the CA40 eliminates false sensor triggering and assures reliable sensor operation even in severe ac or dc weld fields. The model's fully rotatable head allows sensing in any of five positions: the four sides or the top of the sensor. The CA40 can sense all types of metals at the same sensing range, including mild and stainless steel, copper, brass, and aluminum.
In a line of ultra-futuristic projects, DARPA is developing a brain microchip that will help heal the bodies and minds of soldiers. A final product is far off, but preliminary chips are already being tested.
