Protecting human health and safety
The Neuron Tracing and Active Learning Environment (NeuroTrALE) software uses artificial intelligence techniques to create high-resolution maps, or atlases, of the brain’s network of neurons from high-dimensional biomedical data. NeuroTrALE addresses a serious challenge in AI-assisted brain mapping: a scarcity of labeled data for training AI systems to construct atlases essential for study of the brain’s neural structures and mechanisms. The software is the primary end-to-end system to perform processing and annotation of dense microscopy data; generate segmentations of neurons; and enable experts to review, correct, and edit NeuroTrALE’s annotations from an internet browser. This award is shared with the lab of Kwanghun (KC) Chung, associate professor in MIT’s Department of Chemical Engineering, Institute for Medical Engineering and Science, and Picower Institute for Learning and Memory.
Many military and law enforcement personnel are routinely exposed to low-level blasts in training settings. Often, these blasts don’t cause immediate diagnosable injury, but exposure over time has been linked to anxiety, depression, and other cognitive conditions. The Electrooculography and Balance Blast Overpressure Monitoring (EYEBOOM) is a wearable system developed to observe individuals’ blast exposure and notify them in the event that they are at an increased risk of harm. It uses two body-worn sensors, one to capture continuous eye and body movements and one other to measure blast energy. An algorithm analyzes these data to detect subtle changes in physiology, which, when combined with cumulative blast exposure, may be predictive of cognitive injury. Today, the system is in use by select U.S. Special Forces units. The laboratory co-developed EYEBOOM with Creare LLC and Lifelens LLC.
Tunable knitted stem cell scaffolds: The development of artificial-tissue constructs that mimic the natural stretchability and toughness of living tissue is in high demand for regenerative medicine applications. A team from Lincoln Laboratory and the MIT Department of Mechanical Engineering developed latest types of biocompatible fabrics that mimic the mechanical properties of native tissues while nurturing growing stem cells. These wearable stem-cell scaffolds can expedite the regeneration of skin, muscle, and other soft tissues to cut back recovery time and limit complications from severe burns, lacerations, and other bodily wounds.
Mixture deconvolution pipeline for forensic investigative genetic genealogy: A rapidly growing field of forensic science is investigative genetic genealogy, wherein investigators submit a DNA profile to industrial genealogy databases to discover a missing person or criminal suspect. Lincoln Laboratory’s software invention addresses a big unmet need on this field: the power to deconvolve, or unravel, mixed DNA profiles of multiple unknown individuals to enable database searching. The software pipeline estimates the variety of contributors in a DNA mixture, the proportion of DNA present from each contributor, and the sex of every contributor; then, it deconvolves the several DNA profiles within the mixture to isolate two contributors, while not having to match them to a reference profile of a known contributor, as required by previous software.
Each 12 months, tons of of individuals die or suffer serious injuries from heat stroke, especially personnel in high-risk outdoor occupations reminiscent of military, construction, or first response. The Heat Injury Prevention System (HIPS) provides accurate, early warning of warmth stroke several minutes upfront of visible symptoms. The system collects data from a sensor worn on a chest strap and employs algorithms for estimating body temperature, gait instability, and adaptive physiological strain index. The system then provides a person’s heat-injury prediction on a mobile app. The affordability, accuracy, and user-acceptability of HIPS have led to its integration into operational environments for the military.
Observing the world
More than 80 percent of the ocean floor stays virtually unmapped and unexplored. Historically, deep sea maps have been generated either at low resolution from a big sonar array mounted on a ship, or at higher resolution with slow and expensive underwater vehicles. New autonomous sparse-aperture multibeam echo sounder technology uses a swarm of about 20 autonomous surface vehicles that work together as a single large sonar array to realize the very best of each worlds: mapping the deep seabed at 100 times the resolution of a ship-mounted sonar and 50 times the coverage rate of an underwater vehicle. New estimation algorithms and acoustic signal processing techniques enable this technology. The system holds potential for significantly improving humanitarian search-and-rescue capabilities and ocean and climate modeling. The R&D 100 Award is shared with the MIT Department of Mechanical Engineering.
FocusNet is a machine-learning architecture for analyzing airborne ground-mapping lidar data. Airborne lidar works by scanning the bottom with a laser and making a digital 3D representation of the world, called a degree cloud. Humans or algorithms then analyze the purpose cloud to categorize scene features reminiscent of buildings or roads. In recent years, lidar technology has each improved and diversified, and methods to research the information have struggled to maintain up. FocusNet fills this gap through the use of a convolutional neural network — an algorithm that finds patterns in images to acknowledge objects — to routinely categorize objects throughout the point cloud. It can achieve this object recognition across several types of lidar system data while not having to be retrained, representing a serious advancement in understanding 3D lidar scenes.
Atmospheric observations collected from aircraft, reminiscent of temperature and wind, provide the highest-value inputs to weather forecasting models. However, these data collections are sparse and delayed, currently obtained through specialized systems installed on select aircraft. The Portable Aircraft Derived Weather Observation System (PADWOS) offers a approach to significantly expand the standard and quantity of those data by leveraging Mode S Enhanced Surveillance (EHS) transponders, that are already installed on greater than 95 percent of economic aircraft and the vast majority of general aviation aircraft. From the bottom, PADWOS interrogates Mode S EHS–equipped aircraft, collecting in milliseconds aircraft state data reported by the transponder to make wind and temperature estimates. The system holds promise for improving forecasts, monitoring climate, and supporting other weather applications.
Advancing computing and communications
Quantum networking has the potential to revolutionize connectivity across the globe, unlocking unprecedented capabilities in computing, sensing, and communications. To realize this potential, entangled photons distributed across a quantum network must arrive and interact with other photons in exactly controlled ways. Lincoln Laboratory’s precision photon synchronization system for quantum networking is the primary to offer an efficient solution to synchronize space-to-ground quantum networking links to sub-picosecond precision. Unlike other technologies, the system performs free-space quantum entanglement distribution via a satellite, while not having to locate complex entanglement sources in space. These sources are as a substitute positioned on the bottom, providing an easily accessible test environment that may be upgraded as latest quantum entanglement generation technologies emerge.
Superconductive many-state memory and comparison logic: Lincoln Laboratory developed circuits that natively store and compare greater than two discrete states, utilizing the quantized magnetic fields of superconductive materials. This property allows the creation of digital logic circuitry that goes beyond binary logic to ternary logic, improving memory throughput without significantly increasing the variety of devices required or the surface area of the circuits. Comparing their superconducting ternary-logic memory to a traditional memory, the research team found that the ternary memory could pattern match across your complete digital Library of Congress nearly 30 times faster. The circuits represent fundamental constructing blocks for advanced, ultrahigh-speed and low-power digital logic.
The Megachip is an approach to interconnect many small, specialized chips (called chiplets) right into a single-chip-like monolithic integrated circuit. Capable of incorporating billions of transistors, this interconnected structure extends device performance beyond the bounds imposed by traditional wafer-level packaging. Megachips can address the increasing size and performance demands made on microelectronics used for AI processing and high-performance computing, and in mobile devices and servers.
An in-band full-duplex (IBDF) wireless system with advanced interference mitigation addresses the growing congestion of wireless networks. Previous IBFD systems have demonstrated the power for a wireless device to transmit and receive on the identical frequency at the identical time by suppressing self-interference, effectively doubling the device’s efficiency on the frequency spectrum. These systems, nonetheless, haven’t addressed interference from external wireless sources on the identical frequency. Lincoln Laboratory’s technology, for the primary time, allows IBFD to mitigate multiple interference sources, leading to a wireless system that may increase the variety of devices supported, their data rate, and their communications range. This IBFD system could enable future smart vehicles to concurrently connect with wireless networks, share road information, and self-drive — a capability impossible today.
Fabricating with novel processes
Lincoln Laboratory developed a nanocomposite ink system for 3D printing functional materials. Deposition using an active-mixing nozzle allows the generation of graded structures that transition step by step from one material to a different. This ability to regulate the electromagnetic and geometric properties of a fabric can enable smaller, lighter, and less-power-hungry RF components while accommodating large frequency bandwidths. Furthermore, introducing different particles into the ink in a modular fashion allows the absorption of a wide selection of radiation types. This 3D-printed shielding is anticipated for use for shielding electronics in small satellites. This award is shared with Professor Jennifer Lewis’ research group at Harvard University.
The laboratory’s engineered substrates for rapid advanced imaging sensor development dramatically reduce the time and price of developing advanced silicon imaging sensors. These substrates prebuild most steps of the back-illumination process (a technique to extend the quantity of sunshine that hits a pixel) directly into the starting wafer, before device fabrication begins. Then, a specialized process allows the detector substrate and readout circuits to be mated together and uniformly thinned to microns in thickness on the die level moderately than on the wafer level. Both features can save a project thousands and thousands of dollars in fabrication costs by enabling the production of small batches of detectors, as a substitute of a full wafer run, while improving sensor noise and performance. This platform has allowed researchers to prototype latest imaging sensor concepts — including detectors for future NASA autonomous lander missions — that may have taken years to develop in a standard process.
Additive manufacturing, or 3D printing, holds promise for fabricating complex glass structures that may be unattainable with traditional glass manufacturing techniques. Lincoln Laboratory’s low-temperature additive manufacturing of glass composites allows 3D printing of multimaterial glass items without the necessity for costly high-temperature processing. This low-temperature technique, which cures the glass at 250 degrees Celsius as in comparison with the usual 1,000 C, relies on easy components: a liquid silicate solution, a structural filler, a fumed nanoparticle, and an optional functional additive to supply glass with optical, electrical, or chemical properties. The technique could facilitate the widespread adoption of 3D printing for glass devices reminiscent of microfluidic systems, free-form optical lenses or fiber, and high-temperature electronic components.
The researchers behind each R&D 100 Award–winning technology will probably be honored at an awards gala on Nov. 21 in Palm Springs, California.
