Chip-Scale Device ‘Fine-Tunes’ Wireless Communications

Achip-scale optical device, developed by a team from the University of Sydney’s Australian Institute for Nanoscale Science and Technology (AINST), achieves radio frequency signal control at sub-nanosecond time scales. The photonics breakthrough has the potential to provide broader bandwidth instantaneously to more users.

Round Lens. Square Pixels. Accurate Images. Really?

Alens is cylindrical. It captures light in a circular plane for collection onto a rectangular digital sensor plane. This collection of photons is then transformed into electricity by smaller square pixels. Just how do these disparate shapes work together to provide usable images?

Sensors’ Role Evolves as New Wearables Emerge

Microelectromechanical system (MEMS)-based components, such as sensors and actuators, began penetrating the wearable products market about a decade ago, when the first accelerometers replaced mechanical springs in pedometers and step counters.

Lawrence Berkeley National Laboratory

In 1928, physics professor Ernest O. Lawrence left his faculty position at Yale University for a job at the University of California's Berkeley campus. While at Berkeley, Lawrence invented a unique particle accelerator called a cyclotron that would prove his hypothesis: whirling charged particles around to boost their energies then casting them toward a target is an effective way to smash open atomic nuclei. Lawrence won the 1939 Nobel Prize in physics for the cyclotron, and ushered in a new era in the study of subatomic particles.

Virtual Fabrication and Assembly Documentation

Over the years, the term “virtual” has become associated with many different domains. Virtual machines are now commonplace as a substitute for physical laptops or desktops, allowing for the emulation of computer systems. Of course, virtual reality is in the news daily as new headsets, apps, and games provide a substitute for images and sounds, allowing for the simulation of a three-dimensional environment. In the printed circuit board (PCB) space, some fabrication and assembly information such as artwork, drill, netlist, test, and component placement have been conveyed virtually to manufacturing for more than 30 years.

How Metal 3D Printing is Redefining Part Design

It's one of the basic rules of manufacturing: As part complexity increases, so do machining and assembly costs. But what if there were a different way to produce metal parts — one with fewer limitations than traditional milling, turning, and grinding processes, and able to build complex parts in less time and with little human intervention?
