The structure of the electric car
Take for example the engine that drives only one wheel, and connected directly to it. One of the advantages of these motors is that manufacturers can use for other things the space occupied by the conventional engine as these engines are coupled directly to the wheels of the vehicle. This opens a wealth of opportunities [...]
The explosives superdetector
The staffs of the University of Arizona developed a device which can test the air around a person while it passes through an arc similar to a metal detector. Portable units may inspect the baggage in parallel.
The system is not examined samples of material, but that directly tries to find traces of explosives as a [...]
Termocelulas nanotube, generate electricity from waste heat
This is revealed by a study, a collaboration among team Baratunde Cola Georgia Institute of Technology, and specialists from USA, Australia, China, India and Philippine.
The study represents a major technological leap, and that this innovation will be possible to efficiently generate electricity from sources as unattractive as exhaust from vehicles, or the heat generated as [...]
Virtual keyboard on the arm or palm
The new system, called Skinput, has been developed by Chris Harrison, at the Institute of Human-Computer Interaction (HCA II) from Carnegie Mellon University, along with Desney Tan and Dan Morris of Microsoft Research.
Skinput could help people to make better use of large computing power present today in various handheld electronic devices. The diminutive size makes [...]
How electricity moves through cells
Researchers at the University of Minnesota have created a molecular image of a system that moves electrons between proteins in cells. The achievement is a breakthrough for biology and could provide insights to minimize energy loss in other systems, from nanoscale devices to moving electricity around the country.
The research, led by Carrie Wilmot, an associate [...]
New ‘hearing’ maps are real conversation starters
Innovative sound-mapping software based on human hearing has been developed to help architects design out unwanted noise.
The new software generates audibility maps of proposed room designs.
The EPSRC (Engineering and Physical Sciences Research Council) project has been developed at Cardiff University.
These maps show hotspots where conversations would not be intelligible if the room were busy. Architects [...]
Monuments monitored from a distance
A team of engineers from the University of Seville (US) has created a system for monitoring historical monuments by remote control and detecting possible damage. Five years ago the researchers placed various sensors on the Giraldillo, the sculpture that crowns the Giralda, and now they are publishing the results in the journal Structural Health Monitoring.
“The [...]
Webb Telescope’s first primary mirror meets cold temperature specifications, sets program landmark
The James Webb Space Telescope reached a mission-readiness landmark today when its first primary mirror segment was cryo-polished to its required prescription as measured at operational cryogenic temperatures. This achievement sets the stage for a successful polishing process for the remaining 18 flight mirror segments.
Northrop Grumman Corporation is leading Webb’s design and development effort for [...]
Aerial surveillance technology could keep soldiers safer
New technology that enables aerial vehicles to plan and verify missions could mean there is less need for military personnel to conduct dangerous surveillance operations in war zones.
Developed for use in multiple unmanned aerial vehicles (MUAVs), the sophisticated autonomous computer framework - the first of its kind - allows one operator to control a number [...]
Greener memory from random motion
Heat helps in low power data storage scheme
Random thermal fluctuations in magnetic memory can be harnessed to reduce the energy required to store information, according to an experiment reported in the current issue of Physical Review Letters. The development could lead to computer memory that operates at significantly lower power than conventional devices. Markus Münzenberg [...]
