Tumor removal surgeries pose a great challenge even to skillful and experienced surgeons. Up to now, doctors depend exclusively upon their trained eyes when excising pieces of tumors. A new camera system developed by Fraunhofer Institute for Manufacturing Engineering and Auto- mation...

Optical devices like telescopes and microscopes have relied on solid lenses that slide up and down to magnify and to focus. To tune how much light is received, conventional devices use mechanical contraptions like the blades that form the adjustable aperture in cameras. Engineers from the...

A $500 nano-camera that can operate at the speed of light has been developed by researchers in the MIT Media Lab. The three-dimensional cameracould be used in medical imaging and collision-avoidance detectors for cars, and to improve the accuracy of motion tracking and gesture-recognition...

Researchers are building a massive computer system that browses millions of pictures and decides for itself what they all mean. The system at Carnegie Mellon University, called NEIL (short for Never Ending Image Learning) has been searching the Internet for images 24/7 and, in tiny steps, is determining how...

Using under $1,500 worth of materials, including a small commercial MIG welder and an open-source microcontroller, a Michigan Technological University team built a 3D metal printer than can lay down thin layers of steel to form complex geometric objects. Expanded 3D printing would benefit people in...

Researchers have combined antennas and solar cells to work together with unprecedented efficiency. The development is a first step towards more compact, lightweight satellites. The technology could also be deployed in the autonomous antenna systems used in the aftermath of natural disasters.For their...

Researchers from MIT's Research Laboratory of Electronics (RLE) created a new lidar-like system that gauges depth when only a single photon is detected from each location. The new scheme could enable laser rangefinders to infer depth from a hundredth as much light — and to produce images from...

Jim Lux is task manager on FINDER (Finding Individuals for Disaster and Emergency Response), a portable radar device that detects heartbeats and breathing of victims trapped under rubble in a disaster.

A conventional low-noise detector requires a technique to both absorb incident power and convert it to an electrical signal at cryogenic temperatures. This innovation combines low-noise detector and readout functionality into one device while maintaining high absorption,...

Flexible circuits with superconducting wiring atop polyimide thin films are being studied to connect large numbers of wires between stages in cryogenic apparatus with low heat load. The feasibility of a full microstrip process, consisting of two layers of superconducting material...

Retrieval algorithms like that used by the Orbiting Carbon Observatory (OCO)-2 mission generate massive quantities of data of varying quality and reliability. A computationally efficient, simple method of labeling problematic data points or predicting...

This invention is a TecPlot macro of a computer program in the TecPlot programming language that processes data from DPLR solutions in TecPlot format. DPLR (Data-Parallel Line Relaxation) is a NASA computational fluid dynamics (CFD) code, and TecPlot is a commercial CFD post-processing tool. The...

Most single-stranded RNA (ssRNA) viruses mutate rapidly to generate a large number of strains with highly divergent capsid sequences. Determining the capsid residues or nucleotides that uniquely characterize these strains is critical in understanding the strain diversity of these viruses. RECOVIR (an acronym...

Contact Graph Routing (CGR) for Delay/Disruption Tolerant Networking (DTN) space-based networks makes use of the predictable nature of node contacts to make real-time routing decisions given unpredictable traffic patterns. The contact graph will have been disseminated to all nodes...

A model of the manmade orbital debris environment is required by spacecraft designers, mission planners, and others in order to understand and mitigate the effects of the environment on their spacecraft or systems. A manmade environment is dynamic, and can be altered significantly by intent (e.g., the...

This innovation is capable of significantly reducing the amount of time required to stabilize the strain-temperature response of a shape memory alloy (SMA). Unlike traditional stabilization processes that take days to weeks to achieve stabilized response, this innovation...

Submillimeter heterodyne instruments play a critical role in addressing fundamental questions regarding the evolution of galaxies as well as being a crucial tool in planetary science. To make these instruments compatible with small platforms, especially for the study of the...

High-powered motors typically have very low resistance and inductance (R and L) in their windings. This makes the pulse-width modulated (PWM) control of the current very difficult, especially when the bus voltage (V) is high. These R and L values are dictated by the motor size,...

A method was developed of lowering the cost of planetary exploration missions by using an electromagnetic propulsion/launcher, rather than a chemical-fueled rocket for propulsion. An electromagnetic launcher (EML) based at the International Space Station (ISS)...
