Briefs: Sensors/Data Acquisition
Noncontact Sensor Measures Density and Speed of Sound of a Liquid in a Pipeline or Vessel
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.

Thruster-Based Attitude and Translation Control with Minimum Pulse-Count Disturbance Rejection
Thruster-based control typically requires a substantial engineering effort in order to mitigate an important issue: the control system tends to use many thruster pulses to accomplish what a single thruster pulse could do instead. This fundamental problem...

Selective Access and Editing in a Database
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...
Briefs: Energy
Researchers have developed a lithium-ion battery that uses a water-salt solution as its electrolyte — reaching the 4.0- Volt mark for electronics such as laptops — without the fire and explosive...

A reader asks our expert: "How do road conditions impact vehicle-to-vehicle responses?"
Blog: Lighting
Physical chemists at the Georgia Institute of Technology discovered an emerging class of semiconductors with some unexpected moves.
INSIDER: Motion Control
A technology not only allows wheels to know when and how to rotate, but also enables them to work together in interactive teams. Simply monitoring the data generated when the motors inside the wheels...
INSIDER: Transportation
By replacing the cam, a new valve technology may lead to more affordable — and more environmentally friendly — engines.
Question of the Week: Robotics, Automation & Control
Will social robots play a major role in keeping humans happy?
Our lead INSIDER story today featured a discussion of how robots may someday interact with humans.
Blog: Propulsion
Scientists have an idea to deflect Earth-bound asteroids: a 9-meter-tall, 8.8-ton spacecraft dubbed the HAMMER.
INSIDER: Power
Thermoelectric devices generate power when one side of the device is a different temperature from the other. Instead of requiring two different temperature inputs at...
INSIDER: Energy
Researchers at the University of Illinois at Chicago and Argonne National Laboratory have designed a new lithium-air battery that works in a natural air environment and still functioned after a...

Today's humanoid robots are being asked to have more brains than brawn.
Question of the Week: Energy
Will low-cost 'smart glass' catch on?
Our second INSIDER story today featured an achievement from University of Delaware engineers: liquid-activated panels that change from transparent to opaque.
Blog: Test & Measurement
In 1988, a team at Pacific Northwest Laboratories built a mannequin robot. One of the original engineers talked with Tech Briefs about his time making "Manny."
Blog: Photonics/Optics
A switchable window – one that transforms from a clear to tinted state – is not a new invention. What is new, however, is a “smart glass” that is low-cost.
Question of the Week: Imaging
Will laser-based imaging help self-driving cars someday see around corners?
An autonomous-driving technology from Stanford University gives vehicles the capability to "peek" around corners. Tech Briefs spoke with the creators of the laser-based system. To make the technology road-ready, the team still needs to speed-up the data-acquisition...
