LeTV Le Max Pro passes through TENAA

The Chinese regulatory agency TENAA just approved the Le Max Pro. This will include the company’s latest and greatest innovations inside a large-sized smartphone.

The Le Max Pro sports a 6.33-inch display with a QHD resolution. The device will be powered by Qualcomm’s latest Snapdragon 820 SoC with 4GB of RAM. The rear side of the device will house a 21MP camera and the front will sport a much lower-resolution 4MP camera. The device is also expected to include 64GB of native storage and the same 3,400mAh battery as the Le Max.

The Le Max Pro’s design consists of basically all metal. The only downside is the antenna lines that run across the device near the top and bottom. We have seen similar things done on the iPhone 6 and 6s series as well as the HTC One A9. There will surely be a gold-colored variant and more color choices may be available at launch. Pricing should reach north of $500. No availability details or release date information has been specified just yet. We’ll keep you up to date if we hear more on this.

Study shows some 3D printing fumes can be harmful

If you do a lot of 3D printing and are worried about the fumes, you may want to read a new study from US and French researchers. It measured the amount of particles emitted by five 3D printers using nine different filament materials. The new research builds on two previous studies, but the team tested more printers and plastics, and measured more kinds of potentially hazardous fumes. As you might suspect, they discovered that you should be 3D printing in a well-ventilated room or use an enclosed printer with a vent, particularly while printing with ABS, nylon and similar materials.

Those plastics tends to emit styrene, a possible carcinogen, at levels much higher than recommended by California’s Office of Environmental Health Hazard Assessment (OEHHA). As a result, the team advised that “caution should be used when operating many printer and filament combinations in enclosed or poorly ventilated spaces or without the aid of gas and particle filtration systems.”

PLA users don’t have much to worry about, however. Printing with that plastic tends to produce a substance called lactide, which is considered to be non-toxic. The printer itself doesn’t matter much, as the researchers saw little difference in fume levels from model to model. Given that, they recommended that manufacturers focus on designing new types of low-emission, PLA-like filament materials, or design printers with built-in gas and particle filtration. They plan to carry out more detailed, real-world studies in the future.

UK to test self-driving cars on 41 mile ‘connected corridor’

The UK government has dipped into the public purse once again to help finance a handful of autonomous car projects. One of the more interesting proposals is a 41 mile “connected corridor” that will test a number of self-driving car technologies. Specifically, engineers want to look at different connection types — LTE, local WiFi hotspots, LTE-V and DSRC — that could be built into cars and roadside infrastructure such as traffic lights and overhead gantries. The idea is to continuously feed information between traffic agencies, drivers and autonomous vehicles, so that they can all take the safest and smartest course of action on the road. So if a lane is closed or a truck breaks suddenly, everyone is alerted and knows how to react.

The project has a range of contributors, including Jaguar Land Rover, Huawei and Vodafone. The consortium also includes Coventry City Council, Coventry University and the University of Warwick, which makes sense given this is where the “living laboratory” will be based.

Jaguar Land Rover says the experiments, if successful, should make travelling safer and smoother for passengers. When a car wants to change lanes or exit the motorway, for instance, it’ll be safer if every vehicle knows their intended route in advance. Similarly, “platooning” can maintain equal spacing between cars, ensuring safety and maximum fuel efficiency. When an accident occurs up ahead, that information could also be communicated to every vehicleIt’ll test information-sharing between autonomous cars and regular drivers. on the road, including those controlled by human drivers using a mixture of visual and audio-based alerts.

Dr Wolfgang Epple, director of research and technology at Jaguar Land Rover said:

“The approach of an emergency vehicle can often be stressful for drivers. If we can inform the driver, or the autonomous car, much earlier that an emergency vehicle is approaching, we can ensure that the best decisions are made to move the vehicle out of the way safely and conveniently, to let the emergency vehicle pass by.”

Like most of the UK’s autonomous car projects, this will be an early look at how the technology can be rolled out safely. If and when the government decides to properly legislate self-driving vehicles, it’ll be case studies like this one that inform its decisions and the sort of systems that manufacturers need to adopt. An important foundation, not just for road safety but reassuring the public that it’s ready for prime time.
