Confined Space Monitoring of Refrigerants
A refrigerant monitor specifically designed for VRF/VRV (variable refrigerant flow/variable refrigerant volume) systems helps mitigate safety risks. LED flashers and a buzzer alert users when a leak is detected, while a feedback loop is used to isolate and confine affected spaces while corrective actions are carried out.
Novelty Robot Concierge Expected to Improve Along with AI
Considered Italy’s first robot concierge, the humanoid, which can answer questions in English, German and Italian, will now be used year-round at a hotel in Lake Garda where it will help alleviate desk traffic by offering answers to simple, repetitive questions.
These 8 Cities Have the Most Distracted Drivers
Research shows that the evening commute has the greatest amount of distraction, and most distractions occur at speeds of 30–40 mph.
More and More U.S. Schools Allowing Cell Phones in Classrooms
While cell phones are largely absent from most U.S. classrooms, data shows that the devices are becoming more acceptable in such settings thanks to parents’ insistence that the devices be kept with the students for tracking purposes.
Tesla Car on Autopilot During Fatal Crash
Tesla has confirmed that the Tesla vehicle in a fatal crash that killed the driver, 38-year-old Walter Huang, last week in Mountain View, California was on autopilot.
New Discovery for the Development of a Rechargeable Magnesium-metal Battery

Employee Benefit Trends in the US: Small Firms at a Severe Disadvantage
How do insurance benefits compare between large and small companies?
High Torque Motor in a Small Package
A new series of frameless torque motors feature low axial heights and high torque densities. With diameters up to 78 mm and a range of stator heights in each size, they are flexible enough to fulfil the needs of device miniaturization.
Selecting the Best Hub Fastener for a Power Transmission Application
A key aspect of the proper design and operation of power transmission assemblies is how components are fastened to the rotating shaft in order to maintain position and alignment. To optimize manufacturing and operating functionality, many criteria should be considered during the design phase, including some that are frequently overlooked.
Chinese Maker to Locate Solar Panel Plant in Florida
JinkoSolar will supply NextEra Energy with up to 2,750 MW of solar modules — roughly seven million solar panels — over four years.
Threat of Plant Closure May Push Market Changes
The 2,000 MW Mystic Generating Station could close in 2022 unless market reforms are made, its owner says.

Just Lick and Drive: Watch How Lexus Will Use DNA to Customize Vehicles
No key is needed to start a customized vehicle: a revolutionary saliva-powered start-system operates via a DNA ignition sensor on the steering wheel. Just lick and drive.
How Engineers Enhance Creativity
Engineers are just like the rest of us. They are inspired by music, nature, travel and books. Yet, that is probably where the resemblance ends. Because, oftentimes, once inspired, engineers go out and use that inspiration to create something or to solve some problem.
American-made BE-4 Rocket Engine Could End U.S. Dependence on Russian RD-180
The engine recently completed its longest duration test yet, firing at 65% of its maximum power for 114 seconds as engineers swept through a range of fuel/oxidizer mixture ratios.
A New System Produces Clean Perforations with Increased Reliability
A proprietary perforating gun system combines a plug-in gun design with instrumentation that monitors well dynamic unbalance. The system has the ability to support up to forty loaded guns in a single shot which allows the system to selectively perforate multiple producing zones in a single deployment.
Sustainability of Recycled Concrete Aggregate
Researchers examined methods to improve the sustainability of recycled concrete aggregate from construction and demolition waste.
