UAV-Based LiDAR Can Measure Shallow Water Depth

World’s first small-scale topographic and bathymetric scanning LiDAR ASTRALiTe’s edge™ is the world’s first small-scale topographic and bathymetric scanning LiDAR that can detect small underwater objects, measure shallow water depth, and survey critical underwater infrastructure from a small UAV platform. The edge™ can see beneath the water surface at depths from 0-5 meters and is completely self-contained with its own Inertial Navigation System with GNSS, battery, and onboard computer. It weighs about 5 kg and is designed for deployment on UAV systems for faster, safer, and more accurate bathymetric surveys. This patented 2-in-1 topographic and bathymetric LiDAR offers a centimeter-level depth resolution. There are numerous possible applications for this LiDAR, such as coastal mapping and surveying, infrastructure inspection, or even military logistics.  Importance of geo-referencing and motion stabilization “We needed a motion and navigation solution for our LiDAR. Our requirements included high accuracy along with low size, weight, and power” Continue reading UAV-Based LiDAR Can Measure Shallow Water Depth

Robotic Animal Agility

Packed with sensory systems and equipped with revolutionary joints, the ANYmal robot is perfectly at ease on even the roughest terrain An off-shore wind power platform, somewhere in the North Sea, on a freezing cold night, with howling winds and waves crashing against the impressive structure. An imperturbable ANYmal is quietly conducting its inspection. ANYmal, a medium sized dog-like quadruped robot, walks down the stairs, lifts a “paw” to open doors or to call the elevator and trots along corridors. Darkness is no problem: it knows the place perfectly, having 3D-mapped it. Its laser sensors keep it informed about its precise path, location and potential obstacles. It conducts its inspection across several rooms. Its cameras zoom in on counters, recording the measurements displayed. Its thermal sensors record the temperature of machines and equipment and its ultrasound microphone checks for potential gas leaks. The robot also inspects lever positions as well Continue reading Robotic Animal Agility

The Buddy System: Human-Computer Teams

The highest accuracy in face recognition comes through the partnering of a human expert with face recognition software Is that him? Is she the one? A prized attribute among law enforcement specialists, the expert ability to visually identify human faces can inform forensic investigations and help maintain safe border crossings, airports, and public spaces around the world. The field of forensic facial recognition depends on highly refined traits such as visual acuity, cognitive discrimination, memory recall, and elimination of bias. Humans, as well as computers running machine learning (ML) algorithms, possess these abilities. And it is the combination of the two—a human facial recognition expert teamed with a computer running ML analyses of facial image data—that provides the most accurate facial identification, according to a recent 2018 study in which Rama Chellappa, Distinguished University Professor and Minta Martin Professor of Engineering, and his team collaborated with researchers at the National Continue reading The Buddy System: Human-Computer Teams

Industrial Robots Keep the Modern Factory Moving

The relative ease with which Triflex can be repaired and replaced compared to its competition is one of its best features. Conventional six-axis industrial robots typically run a series of cables along the outside of the robotic arm to control power consumption, movement and other dynamic functions. These cables are usually housed in a plastic or rubber tube or tied together using materials as rudimentary as rubber bands or duct tape. As the robotic arm twists, turns and bends, the cables themselves can get tied up in knots or even fray or snap from the force of the machine’s movement. Any damage to the housing or cables necessitates shutting down production for repairs or replacement and costs manufacturers valuable time and money. Automotive industry experts estimate that it takes an average of five hours to replace a standard corrugated hose at an estimated cost of $10,000 a minute to the Continue reading Industrial Robots Keep the Modern Factory Moving

Putting Skin, Heart, and Soul in the Game of Solving Biomedical Challenges

Millimeter-wave imaging is cheaper, safer, less power-intensive and much more portable than other types of body imaging. Developing algorithms and learning-based systems to support potentially life-saving biomedical devices is more than abstract research for Stevens Institute of Technology electrical and computer engineering assistant professor and senior IEEE member Negar Tavassolian. “I’ve always been interested in solving medical problems with commercially viable technology,” says Tavassolian, whose work is affiliated with the Stevens Institute for Artificial Intelligence. “I like to make things and see how they can help somebody.” Tavassolian was granted a National Science Foundation (NSF) CAREER Award to leverage millimeter-wave technology in her quest to use artificial intelligence and other emerging technologies to develop an innovative, portable dermatological application to create a high-resolution image of a patient’s skin for early detection of skin cancers. Millimeter-wave imaging (at a frequency of 30 to 300 GHz) is cheaper, safer, less power-intensive and Continue reading Putting Skin, Heart, and Soul in the Game of Solving Biomedical Challenges

Advance Academic Research With the NI Platform

Every day, researchers use the NI platform to push the boundaries of discovery. A Note to Academic Researchers Every day, researchers use the NI platform to push the boundaries of discovery. They are driven by the grand challenges humanity faces and the economic and technical trends that are revolutionizing wireless communications, transportation, and energy. The ideas, theories, and prototypes that start in academic research labs scale to ever more complex applications and eventually impact all our lives in the form of commercial technology. As varied as their research focus areas might be, academics face similar challenges regardless of domain. The goal of NI has always been to help scientists and engineers spend their time on the novel and the innovative by providing a platform with the accuracy, repeatability, and scalability they need to validate and prototype research. This handbook serves as a space for us to share insights and best Continue reading Advance Academic Research With the NI Platform

Choosing Sensors for Medical Applications

Sensor based monitoring is becoming popular among the aging population. Here’s how to select a sensor to fit your application and parameters. With the ever growing and aging population, patient auto-monitoring systems are becoming more and more popular. Their popularity stems from being both consistent and repeatable in addition to being low cost. Sensor-studded monitoring instruments in this category are also versatile because they can be used both in hospitals and at home. Selecting a sensor can be simple if the application and the parameters that need to be monitored are clearly understood. The most complicated sensors are implantables, followed by sensors used in catheters (through incision) and sensors used in body cavities, sensors that are external but come in contact with body fluids and sensors for external applications. IMPLANTABLE SENSORS Implantable sensors need to be small, lightweight, and compatible with body mass as well as require very little power Continue reading Choosing Sensors for Medical Applications
