New programmable angle sensors

Novotechnik U.S. has just introduced the Vert-X 37E Series of programmable touchless rotary sensors that use a magnetic pick-up secured to the rotating object, so there is no direct mechanical linkage between the shaft and the measuring system -- and therefore no wear. The hermetically sealed Vert-X 37E Series can be programmed by customers or at the factory, so customers can order angle sensors optimized for their specific application. These sensors can help achieve time and cost savings by eliminating the need for other components to specify the angle end points, choose an intermediate plateau, sense of rotation function, CW or CCW, or create V-output.

Guard against Li-ion battery overcurrent and overcharging

The ITV Series from Littelfuse is a three-terminal, surface-mountable Li-ion battery protector designed to guard against the damage caused by both overcurrent and overcharging. It's a good solution for protecting power tools, robotic appliances, e-bikes and e-scooters, uninterruptible power supplies (UPS), emergency radios, and more. The innovative design provides fast response and reliable performance to interrupt the charging or discharging circuit before the battery pack becomes overcharged or overheated. Five packages available with current ratings from 12 A to 45 A.

70 trillion pictures per sec: New ultra-fast camera is quick enough to see waves of light

By Emily Velasco, California Institute of Technology

Just about everyone has had the experience of blinking while having their picture taken. The camera clicks, your eyes shut, and by the time they open again, the photo is ruined.

A new ultra-fast camera developed at Caltech, were it aimed at your lovely face, could also capture you looking like a dunce with your eyes shut, except instead of taking just one picture in the time it takes you to blink, it could take trillions of snaps.

The new camera developed in the lab of Lihong Wang, Bren Professor of Medical Engineering and Electrical Engineering in the Andrew and Peggy Cherng Department of Medical Engineering, is capable of taking as many as 70 trillion frames per second. That is fast enough to see waves of light traveling and the fluorescent decay of molecules.

The camera technology, which Wang calls compressed ultra-fast spectral photography (CUSP), is similar in some respects to previous fast cameras he has built, such as his phase-sensitive compressed ultra-fast photography (pCUP) device, which can take 1 trillion frames per second of transparent objects and phenomena.

CUSP combines a laser that emits extremely short pulses of laser light that last only one quadrillionth of a second (one femtosecond) with optics and a specialized type of camera. The optics break up individual femtosecond pulses of laser light into a train of even shorter pulses, with each of those pulses capable of producing an image in the camera.

Wang says the technology could open up new avenues of research in fields that include fundamental physics, next-generation semiconductor miniaturization, and the life sciences.

"We envision applications in a rich variety of extremely fast phenomena, such as ultra-short light propagation, wave propagation, nuclear fusion, photon transport in clouds and biological tissues, and fluorescent decay of biomolecules, among other things," Wang says.

A paper describing the technology, titled, "Single-shot ultra-fast imaging attaining 70 trillion frames per second," appears in the April 29 issue of Nature Communications. Wang's co-authors include Peng Wang, postdoctoral scholar in medical engineering, and Jinyang Liang, formerly of Caltech and now at the National Institute of Scientific Research in Quebec.

Funding for the research was provided in part by the National Institutes of Health. Wang is also affiliated with the Tianqiao and Chrissy Chen Institute for Neuroscience at Caltech.
