Coming Soon - Polarimetric Radar for Autonomous Drive

In Conjunction with SAEThe 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.

How To Substantially Reduce Encoder Cost While Gaining Functionality With Multi-Turn Rotary Position Sensors

Many applications require rotation counters that can measure angles greater than 360º. However the low-cost 10-turn potentiometers most design engineers are familiar with can’t always meet user requirements for resolution and reliability. As an alternative, optical absolute encoders are too expensive for many applications. These solutions require a continuous power supply or they will lose count when power is restored. Also, geared technology/rotation counters are subject to significant wear.

Will the voice become a mainstream way to control our devices?

This year's Consumer Electronics Show (CES) in Las Vegas showcased many new consumer products featuring voice control. LG, for example, introduced a smart refrigerator equipped with Amazon's Alexa voice service. Other CES technologies with voice-recognition capabilities included televisions, home lighting systems, and vehicles. Last Tuesday, Shawn Dubravac, Chief Economist of the Consumer Technology Association, said vocal computing is replacing the traditional graphical user interface, and "the ability to infuse AI into small things at relatively low cost is present." What do you think? Will the voice become a mainstream way to control our devices?

Biomarker Sensor System and Method for Multi-Color Imaging and Processing of Single-Molecule Life Signatures

NASA’s Jet Propulsion Laboratory offers a method to manufacture biomarker sensor arrays with nanoscale resolution and active regions on the order of 1 micron by applying nanolithographic direct-write techniques to the fabrication of Silane chemistry sensors on a transparent substrate. This novel technology enables extremely fine patterns of detectors suitable for multicolor imaging of single-molecule samples at resolutions far below the diffraction limit. The extremely small size of these sensors allows for rapid, highly specific screening for hundreds of functionalities within a single, small, integrated microfluidics chip.

Device and Method of Scintillating Quantum Dots for Radiation Imaging

Potential applications include medical imaging and aircraft inspection.NASA’s Langley Re search Center has developed Scintillating Quantum Dots for Imaging X-rays (SQDIX) technology that enables the creation of x-ray detectors that are more sensitive than current x-ray detectors. In addition to superior sensitivity, SQDIX also offers the promise of reducing the cost of x-ray detectors by at least a factor of 10. Simply stated, SQDIX has the potential to change the way that x-ray detection is done.

Lightning Protection and Detection System

An array of SansEC sensors can cover a selective area of the aircraft surface, providing both mitigation and damage sensing.NASA’s Langley Research Center has developed a sensor technology for structural health monitoring on composite aircraft surfaces. When conventional aircraft are struck by lightning, the result can range from no damage to serious damage requiring extensive repairs that can take the airplane out of service for an extended period of time. The SansEC technology is a proven wireless sensing platform capable of measuring the electrical impedance of physical matter in proximity to the sensor based on a change in its resonance response. The sensor also exhibits a unique characteristic to disperse the lightning strike current to help mitigate lightning damage. In this application, an array of SansEC sensors will cover a selective area of the aircraft surface, providing both mitigation and damage sensing.
