Finger Vein Authentication Uses Smartphone Camera
The advantage of finger vein authentication is that the characteristics used for biometric identification are in vivo, making it more difficult to forge or spoof.
Researchers to Test Energy-harvesting Computers with Satellites
The systems were developed to counter the fact that while radio waves, solar energy, heat, and vibrations can power devices, harvested energy can lead to periodic power failures and unreliable behavior.
"Clever Buoy" Uses Sonar and Software to Warn of Sharks
The system uses multibeam sonar transducers that are mounted on the ocean floor, together with custom detection software, to scan for shark-like objects.
The Lowest Vehicular Emissions? Batteries vs. Fuel Cells
The future cost and climate benefits of the two power technologies are compared for one California community.
"Bionic" Chip Will Aid Study of Neurological Diseases
The chip mimics the natural biological contact between brain cells, essentially tricking them into believing they are connecting with other brain cells.
A Solution for Phantom Load
All electronics have switches that turn electrical flow on and off throughout the circuitry. But unlike a mechanical switch, these waste small doses of electricity while they are in a waiting state.
Wireless Implant Helps Paralyzed Primates Walk
A wireless brain-control system recreates signals recorded from the brain and stimulates electrodes in the leg.
Autonomous Driving Extended to Scooters
Autonomous vehicle technology now encompasses scooters, potentially affording the elderly and disabled a greater measure of independence.
"BioSwimmer" Tested for Port Inspections
BioSwimmer has the ability to twist and turn in limited space within the water, which sets it apart from most other remotely operated vehicles.
"Sensing Skin" Detects Damage in Structures
The skin consists of three layers, which can be painted onto the surface of a structure or pre-assembled and attached like wallpaper.
Increasing Energy Density in Lithium Batteries
When lithium batteries are charged the first time, they lose 5%-20% of their energy in that first cycle.
Stanford Claims Solar-to-Hydrogen Efficiency Gain
Research points to the potential of photovoltaic-electrolysis systems for cost-effective solar energy storage.
A Twist for Surgical Robotics
A startup called Medrobotics has launched a surgical robotic system that features a design that could make robots a much more common fixture in operating rooms.
Lithium-Ion Battery Grows Back Together
In contrast to conventional lithium-ion batteries, the lithium compounds cannot leak out of the electrodes, either while in use or after a break.
Design for an Infinitesimal Computing Device
Key to the design is the use of a logic system called material implication logic combined with memristors.
3D Hand Models May Pose Security Risks
A fake 3D hand, essentially a spoof, with someone’s fingerprints could potentially allow a crook to steal a person’s identity.
IBM's Watson to Support GM's Updated OnStar System
Watson will learn the driver's preferences, apply machine learning, and sift through data to recognize patterns in driver decisions and habits.
Changing Semiconductor Properties at Room Temperature
The process may offer a path to electronically triggering changes in the properties of semiconductor materials.
Lidar to Boost Armored Vehicle Crews' Awareness
The goal is to improve the mobility and survivability of armored vehicles without adding more armor and weight.
"Pollutant" Compound Could Be Used in Dual-Ion Batteries
Research shows that at least one of the compounds known as polycyclic aromatic hydrocarbons can function as a long-lasting, high-performance cathode in dual-ion batteries.
