A vision system provides a close-up of a heart pump valve, taking 100,000 frames per second to provide a close look at anomalies as it opens and closes. To help engineers figure out what causes these problems, the system is synchronized to data monitoring equipment that measures pressure flow and other parameters.
This system, developed by DRS Data & Imaging Systems, Inc. of Oakland, NJ, is also being used in automotive crash testing, making it possible to match data from accelerometers, pressure sensors and other sensors with images taken during the milliseconds of a collision that takes hours to set up. “If customers require synchronized data, the camera runs as a slave to the acquisition instrument. The board clocks the camera so it can synchronize video and data,” says Tim Callenbach, manager of high speed cameras at DRS, a company that works closely with military customers that want high end products. While DRS focuses on the high end, it’s riding the same trends that impact the broader machine vision field, where falling prices and simplified setup are helping spark solid market growth. A number of vendors are helping promote the field in a Vision Pavilion at NIWeek.Other vendors in Austin include Flir Systems of Wilsonville, OR. Flir makes infrared cameras, which are seeing increasing use in applications where normal cameras can’t provide enough data. By sensing IR, the machine vision systems can determine whether a vehicle’s rear window defogger or heated seat elements are all operating correctly. Cameras from Basler AG are being used in a costly popcorn popper inspired by Rube Goldberg. NI counts out 300 kernels using its vision system, then heats them up and tips the popcorn out when it’s finished. Basler is also demonstrating a 4 Mpixel camera for more demanding applications.Lens maker Navitar Inc. of Rochester, NY is showing a number of lenses that provide specialized views for various tasks. “Semiconductor manufacturing equipment vendors are our biggest customers,” says Joe Corsi, regional account manager.
Biomimicry has already found its way into the development of robots and new materials, with researchers studying animals and nature to come up with new innovations. Now thanks to researchers in Boston, biomimicry could even inform the future of electrical networks for next-generation displays.
Clean diesel continues to be the fuel of choice for transportation authorities in major U S cities, in spite of competitive options aimed at reducing emissions, according to a nonprofit agency that represents diesel engine and equipment manufacturers.
A panel at this year's Consumer Electronics Show in Las Vegas discussing upcoming FAA regulations for non-military drones brought out many of the issues that concern both industry and federal regulators.
