The XL-80 interferometer from Renishaw Inc. is lighter and more portable than its predecessors, making it simpler for quality control and maintenance technicians to calibrate manufacturing and laboratory equipment. The instrument can measure distances as long as 260 ft, yet it still provides measurement speeds of up to four meters per second.
Both speed and accuracy have been upgraded substantially. It runs at 50 kHz, compared to only 5 kHz for Renishaw units that are now in the field. Resolution is 1 nanometer, while accuracy is 0.5 ppm, substantially better than its predecessor's 0.7 ppm. Weight including cables, power supplies and sensors is under seven lbs. The unit can employ optics from previous generation hardware, helping keep costs down.
The National Highway Traffic Safety Administrationís recent backup camera mandate could open the door to more vehicle innovations, including better graphical displays, 360-degree camera views, and the increased use of Ethernet.
With support from National Instruments, a group of dedicated students from Connally High School in Austin, where more than 50% of the students are at risk of not graduating, have created a successful robotics team that is competing in the FIRST World Championships.
