Securing and Validating Critical Vision Data

Manufacturing companies are placing increasing emphasis on data security throughout their operations to protect confidential data and to validate that their systems are protected against unauthorized and unwanted changes. The critical role that vision plays in many manufacturing processes makes it essential that system security be improved for vision applications. A new generation of vision-specific security tools offers improvements in access control, change tracking, auditing, and general network security to help ensure the integrity of vision applications while at the same time protecting data confidentiality.

Laser Scribing of Photovoltaic Materials

Solar technologies use the sun’s energy to provide heat, light, hot water, electricity, and even cooling, for homes, businesses, and industry. Despite sunlight’s significant potential for supplying energy, solar power provides less than 1% of U.S. energy needs.

Hyperspectral Imaging What is it? How does it work?

Hyperspectral imaging has grown increasingly popular over the past ten years in military, industrial, and scientific arenas. The ability to precisely characterize the color of a viewed item, whether a camouflaged vehicle, a bruise on an arm or on fruit, or a wide swath of vegetation, allows the user to make informed decisions only dreamed of in the past. What once required large, delicate, and expensive laboratory spectrometers is now being done in real time aboard satellites, unmanned aerial vehicles, and portable handheld units.

Using CVD Diamond to Cool Hot Devices

Increasing power densities and decreasing transistor dimensions are hallmarks of many of today’s semiconductor devices, including high-voltage power transistors, laser diodes, and RF power amplifiers. GaN devices, such as power converters for photovoltaic cells and cellular base-station power amplifiers, are further enabling higher power densities in smaller die sizes. Both trends are significantly increasing the thermal management challenge within the chip and surrounding package or module.

Using Adaptive Optics to Perform Deep-Tissue Cell Imaging

In biological imaging, the object of interest is not always in plain sight. This is especially true when performing microscopy of cells buried deep within tissues. The tissues covering the cells tend to bend and scatter the light passing through them, which prevents acquiring sharp images of the cells below. To overcome this, researchers at a leading science campus developed a novel way to use adaptive optics in microscopy.

Solar Powered UAVs

The use of unmanned aerial vehicles (UAVs) has been increasing worldwide as demands for agile, rapid, targeted response forces have grown. UAVs provide surveillance and detection capabilities to these smaller forces that are unmatched by other technologies. As the reliance on UAVs increases, the short endurance times of existing UAV solutions become a significant factor. Existing commercial solutions have endurance ranging from 45 minutes to 4 hours, limiting both operational range and loiter capabilities. To increase endurance, UAV manufacturers have begun to target technologies ranging from increased performance batteries, improved control algorithms, fuel cells and other alternative power sources. While solar powered UAVs have long been a desired goal, existing solar technologies have characteristics that have made solar integration difficult and limited their integration.
