Sensors & Test

Smartphones and sensors have produced a treasure trove of pictures, many tagged with pertinent information identifying content. Using this vast database of cross-referenced images, convolutional neural networks and other machine learning methods have revolutionized the ability to quickly identify natural...

This NASA innovation is a biologically inspired system management method designed to make sensor webs as well as other autonomous and autonomic systems more self-directing and self-managing. Based on the mechanisms of cell apoptosis, this method ensures safe and correct operation...

NASA’s Goddard Space Flight Center has developed a method to collect suspicious data and analyze them without extensive costs. A common challenge in complex computer systems is the identification of unauthorized use, which can be...

Engineers at Goddard Space Flight Center have overcome limitations plaguing the satellite sector since its inception through the development of a robotic system allowing for the autonomous capture and servicing of in-orbit satellites. By...

The need for non-invasive, real-time measurement of the density and speed of sound of a liquid led to the development of an ultrasonic sensing technique based upon the reflection of ultrasound at the solid-fluid interface.

NASA has developed a method and system that provides selective access to different portions of a database by different subgroups of database users. In this system, two or more members of a given access subgroup can simultaneously edit a document accessible to each member. This database system provides...

The Pressure Sensor Mechanism is designed to measure or monitor tactile pressure. It is based on passive Radio Frequency Identification (RFID) sensor tags and is applicable to a variety of systems. As RFID sensors transmit information wirelessly, they eliminate many challenges associated with traditional wired systems such...

Stanford University is developing a laser-based imaging technology that allows cars to peek around corners.

In this week's Tech Briefs TV video, Rice University scientists demonstrated an ability to embed graphene into paper, cloth, and even your breakfast. Why etch patterns into toast? James Tour, a chemist at Rice University, envisions never-before-seen applications, like embedding electronics as a self-cooking heat...

Have a product design idea? The "Create the Future" Design Contest is now open for submissions until July 2, 2018.

A temperature sensor with practically no effect at all on the temperature of the object measured has been created in the laboratory by researchers at the University of São Paulo (USP) and the University of Campinas (UNICAMP) and is awaiting a patent for commercial production.
