Polarimetric Radar for Autonomous Drive

In Conjunction with SAE

The automotive industry is moving rapidly from driver assistance applications to safety-critical perception systems that independently make decisions. These perception systems need to be able to reliably detect the orientation and the type of target in any environmental condition. This 30-minute Webinar examines a new polarimetric radar sensor for autonomous and highly automated drive applications. Experts discuss how this technology will dramatically improve the performance and reliability of automotive sensor suites in all environmental conditions.

Will robotic voice assistants improve children's ability to learn?

This week's Question: Toymaker Mattel recently announced the introduction of a smart baby monitor; The voice-controlled "Aristotle" uses artificial intelligence (AI) to automate functions like changing lights, playing lullabies, or triggering white noise. With an estimated 25 million voice assistants expected to sell this year — like Amazon's Alexa, Google Home, and Microsoft's Cortana — some researchers believe that the technology will impact its young users. Supporters of voice assistants say children have always used mainstream technology as learning tools. Opponents, however, suggest that the gadgets are another device that de-emphasizes the importance of interpersonal skills. What do you think? Will robotic voice assistants improve children's ability to learn?

Wireless Tamper Detection Sensor and Sensing System

The sensors can detect and locate cracks, material strain, or impact damage.

NASA's Langley Research Center researchers have developed a wireless, connection-free inductor capacitor sensor system that can be placed on or embedded in materials and structures to monitor for and detect damage. The sensors can also be used to detect package tampering and pilfering. This innovation — SansEC (Sans Electrical Connections) — makes sensors more damage resilient and more environmentally friendly to manufacture and use.

CERTIFICATES AND SIGNATURES: How to Ensure Authentication in the IoT

On October 21, 2016, the Internet saw a significant distributed denial of service (DDoS) attack, conducted via a botnet comprising many co-opted Internet-connected devices. The attackers of the network infrastructure were able to control these Internet-of-Things (IoT) devices for a number of reasons, including a lack of strong authentication. Loaded software turned the machines into puppets that interfered with Internet traffic for millions of users.

NASA Navigation Sensor May Land in Applications Beyond Mars

Although a NASA-built sensor being tested in the Mojave Desert this summer will be used to support the safe landing of rovers on Mars, one of the technology's lead researchers sees other commercial possibilities. Principal Investigator Farzin Amzajerdian and his team at NASA's Langley Research Center developed the Navigation Doppler Lidar, a bread-box-sized sensor system that could someday play a role in aircraft navigation and even driverless car applications.
