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.

High-speed camera for manufacturing analysis

High-speed video capture can help engineers troubleshoot manufacturing processes and researchers analyze fast-acting events, but traditional large-format, high-speed cameras can quickly run out of storage. Mikrotron has solved this problem with its MotionBLITZ CVR recording system that combines an EoSens 4MP CoaXPress color camera remotely connected to an industrial-grade DVR. The MotionBLITZ CVR is capable of recording video sequences of up to 12 sec at 560 fps and 2,336 x 1,728-pixel resolution directly into RAM, then quickly downloaded to the 2-TB RAID drive. It also can be configured to record up to 35,000 fps in smaller image formats. The detachable camera easily fits into tight spaces.

New low-noise, solid-state relays

Instead of using moving components as mechanical power relays do, solid-state relays (SSRs) from Sensata Technologies rely on silicon-controlled rectifier (SCR) technology that allows SSRs to provide quieter operation (no clicking), longer life, and more precise switching control. The new LN series SSRs from Sensata's Crydom brand conform with IEC 60947-4-3 Environment B and CISPR 11 standards for low-voltage domestic, commercial, and light industrial locations and installations, and are compliant with C-UL-US and TUV certifications. The LN Series of panel-mounted solid-state relays offers reliable back-to-back SCR switching up to 75 A at 528 VAC.

Innovative resettable pin puller for advanced aerospace and weapons platforms

Marotta Controls has just introduced its newly patented Shape Memory Alloy (SMA) pin puller -- a non-pyrotechnic resettable locking device. Initially developed for missile fin locks, the SMA pin puller is suited for any critical separate-and-deploy mechanism where precision timing and confidence in performance are high priorities. Replacing a single-use pyrotechnic solution with the SMA pin puller enables customers to fully vet a lock's functionality during the all-up test stage, resulting in a more reliable solution. The SMA pin puller is also significantly smaller than a traditional pyrotechnic puller, which requires additional components to safely disengage the locking pin without firing the device.

Top 5 reasons for solder joint failure

Solder joint reliability is often a pain point in the design of an electronic system. According to Tyler Ferris at ANSYS, a wide variety of factors affect solder joint reliability, and any one of them can drastically reduce joint lifetime. Properly identifying and mitigating potential causes of solder joint failure during the design and manufacturing process can prevent costly and difficult-to-solve problems later in a product lifecycle.

Isolating and dissipating the impact of lightning strikes on composite wings

Aircraft with an aluminum fuselage and wings can readily conduct the charge from a lightning strike, allowing the current to move along the skin and pass back into the atmosphere. But composites are significantly less conductive than aluminum. Composite wings need isolating and dissipating tubes to slowly dispel the static charge from a lightning strike, thereby preventing arcing in the system.

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.
