Intelligent Photonic Multi-Sensor Solutions

With the Internet of Things (IoT) quickly rising in front of us, it would be easy to get caught in the trap of thinking that both the trajectory and applications will be somewhat predictable. While hindsight is 20/20, the future can be a little trickier to envision. We can likely all agree that when we saw the first brick-sized wireless telephone, it wasn’t hard to tap our creative problem solving to conclude that subsequent generations were going to get smaller, cheaper and generally “better”. But few people could have envisioned the “smartphone,” let alone Apple’s first edition iPhone. Fewer still looked from that first brick to an age of sensor-driven, cloud-connected apps in the palms of our hands.

UV-VIS Micro-Spectrometer

Hamamatsu Corporation (Bridgewater, NJ) has announced the release of the C12666MA microspectrometer, a UV-VIS spectrometer about the size of a fingertip. Its miniature components, fabricated using MEMS (micro-electro-mechanical systems) technology, allow it to be a fraction of the size of traditional spectrometers. In addition, its hermetically sealed package makes it usable in high-humidity environments that traditional spectrometers do not tolerate well.

310 nm, sub 800 ps Picosecond Pulsed LED

Edinburgh Instruments (Livingston, UK) has released a 310 nm picosecond pulsed LED with a sub-800 picosecond typical pulse width. This LED is optimized for Time Correlated Single Photon Counting (TCSPC). The EPLED 310 is a compact, robust, maintenance free, fully integrated system supplied in a single package. It is pre-adjusted for an optimum pulse width of

UV-Visible-NIR Polarization Spectroscopy

CRAIC Technologies (San Dimas, CA) recently announced the addition of UV-visible-NIR polarization spectroscopy capabilities to CRAIC microspectrophotometers. This feature is offered as a package that allows the user to measure polarization spectra in either transmission or reflectance modes. With the ability to measure polarization microspectra™ in the ultraviolet, visible and near infrared regions, the UV-visible- NIR polarization package represents a powerful new tool for both materials science and biological research.

Reducing Power-On/Off Glitches in Precision DACs: Part 2

Part 1 of this article introduced a phenomenon called power-on/off glitch. The example discussed the impact of this phenomenon on a motor control system. We limited our analysis to a DAC where the output buffer is powered on in normal mode: zero-scale or mid-scale. In Part 2, we analyze when the DAC output is powered on in high-impedance mode. We present a mathematical model for the power-on glitch, followed by board-level solutions to minimize it.

Autonomous Robots Keep Warehouse Running Green

YLOG, a startup company in Austria, uses an intelligent and very environmentally friendly logistics system that is winning an increasing number of customers. The technology makes use of individual, freely moving Autonomous Intelligent Vehicles (AiVs) that detect each other, observe right-of-way rules, recognize one-way routes, and complete their tasks fully autonomously without intervention from or coordination by a central computer.
