Data Logger Aids in Development of New Vehicles

A new data logger developed by Fraunhofer researchers simultaneously collects data from vehicles with combustion engines, electric drives, external sensors, and location data, and permits the development of new hybrid and electric vehicles. Once installed in a car, it records all the relevant operational data from the trips the car makes over a period of several weeks or months, enabling evaluation of how a car is used, including characteristics such as route profiles or driving style – when does the driver drive more cautiously, when more aggressively?

High-Altitude Radiation Tests Will Protect Airline Travelers

The RaD-X payload ascended into the stratosphere to measure cosmic radiation coming from the Sun and interstellar space. (NASA) Imagine you’re sitting on an airplane cruising at 36,000 feet. Just above you, high-energy particles, called cosmic rays, are zooming in from outer space. While we are largely protected from this radiation on the ground, up in the thin atmosphere of the stratosphere, these particles can affect humans and electronics alike.

Hydraulic Carts Streamline Structural Tests for Aircraft

The Flight Loads Laboratory (FLL) at Armstrong Flight Research Center tests the strength and endurance of aircraft structures using hydraulic actuators to apply forces that simulate the stresses of takeoff, flight, and landing. The contract to build the FLL’s next-generation hydraulic controller system went to Moog Inc., an East Aurora, NY-based company that specializes in motion control systems. The company designed a multi-function mobile cart that not only houses the hydraulics for up to eight actuators, but also includes most of the necessary electronics, which were previously housed in the control room.

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.

Smart Buoy Measures Water Pollutants

The current way of using the multi-algae sensor; in the future, it will be operated automatically from buoys, together with other sensors. (Photo: bbe Moldaenke) Extensive water monitoring is indispensable for drinking water supply and water protection. Researchers have developed a smart monitoring system that combines various technologies in a depth-profile-measuring multi-sensor buoy for monitoring water bodies and algae growth. Conventional monitoring strategies are frequently based on a multitude of independently acting sensor systems. This aggravates and slows down integrated data evaluation.
