Time-to-Digital Converter

Mouser Electronics, Inc., (Mansfield, TX) is now stocking the TDC7201 time-to-digital converter from Texas Instruments (TI). The TDC7201 is designed for use with ultrasonic, laser, and radar range finding equipment using time-of-flight (TOF) technique. TI’s TDC7201 time-to-digital converter has two built-in time-to-digital converters (TDCs) that can be used to measure distance down to 4 cm and up to several kilometers using a simple architecture. The TDC7201 features a wide measurement range of 0.25 ns to 8 ms and high accuracy of 28 ps. The device has a single shot resolution of 55 ps, (equivalent to 0.825 cm).

Single Photon Counting Module

Excelitas Technologies® (Waltham, MA) has introduced SPCM-NIR, a Single Photon Counting Module specifically selected and performance-optimized for the near-infrared (NIR) wavelength spectrum. This NIR-spectrum enhanced device is designed to support long-range LIDAR, quantum communication and microscopy applications. The Excelitas SPCM-NIR uses a specially selected silicon avalanche photodiode (SLiK) with peak single photon detection efficiency (PDE) at 780nm, typically better than 73%, while maintaining uniformity over a 180 μm diameter active area.

CoaXPress Frame Grabber

Responding to the need to create a cost-effective, high-speed interface to fully leverage CXP cameras, BitFlow (Woburn, MA) has introduced the Aon-CXP single link CoaXPress frame grabber. The Aon is powerful enough to support camera speeds up to 6.25 Gigabits/second, which is almost twice as fast as USB3 and over six times the speed of current offerings of GigE Vision. While capturing video at those speeds, it is simultaneously sending control commands, triggers and up to 13 W of power over a single piece of 75 Ohm coaxial cable.

Oldest Known Planet-Forming Disk Discovered

A group of citizen scientists and professional astronomers, including Carnegie's Jonathan Gagné, joined forces to discover an unusual hunting ground for exoplanets. They found a star surrounded by the oldest known circumstellar disk: a primordial ring of gas and dust that orbits around a young star and from which planets can form as the material collides and aggregates.

Help for Fishing Vessels to Locate Their Catch

Professional fishermen have been wanting to obtain data that could help them better predict where fish can be found. A solution may be around the corner. They may get a decision-making tool that tells them where fish shoals are located and how their vessels can be operated as economically as possible, report researchers.

Exploring Vast 'Submerged America' and Bubbling Methane Vents

Five hundred vents newly discovered off the U.S. West Coast, each bubbling methane from Earth's belly, top a long list of revelations about "submerged America" being celebrated by leading marine explorers meeting in New York. "It appears that the entire coast off Washington, Oregon, and California is a giant methane seep," says RMS Titanic discoverer Robert Ballard, who found the new-to-science vents on summer expeditions by his ship, Nautilus.

Creating 3D Hands to Keep Us Safe and Increase Security

Creating a 3D replica of someone's hand, complete with all five fingerprints, and then breaking into a secure vault may sound like a plot from a James Bond movie, but Michigan State University Distinguished Professor Anil Jain recently discovered this may not be as far-fetched as once thought and wants security companies and the public to be aware of the possibility.

In 40 years, data acquisition products have evolved from paper-based chart recorders and analog tape machines, to computer-based instruments. As a result, the relatively slow pace of improvements in performance that typified data recorders for nearly a century is now swept along on the fast-moving current of computer technology advances.

Remote-Controlled Robot Inspects Suspicious Packages

Researchers at the Fraunhofer Institute for High Frequency Physics and Radar Techniques (FHR) have created a sensor suite that will help emergency services more effectively detect improvised explosive devices. The system records the shape of suspicious packages and creates 3D images of their contents.

GRAVITE Pull Server

Government Resource for Algorithm Verification, Independent Test, and Evaluation (GRAVITE) system is a National Oceanic and Atmospheric Administration (NOAA) system, developed and deployed by Joint Polar Satellite System (JPSS) Ground Project to support Calibration and Validation (Cal/Val), Data Quality Monitoring, and Algorithm Investigation, Tuning and Integration. GRAVITE enables novice and expert users to discover and obtain data easily by using standard protocols. The Pull Server is a component of the GRAVITE version 3.0 (GV3.0) system. It provides a mechanism to download remote data file(s) using easy-to-understand download rules. When there are few rules pertaining to the same remote location, it can be grouped using a product paradigm. A download rule can be defined with only three pieces of information: remote server, source, and target location. The source and target location can be specified using calculated fields as well as regular expressions. The rules are then converted into a “wget” statement, which is a popular utility for downloading remote files. This solves most of the compatibility issues with connecting to a remote server.
