Communicating with Cells: Biologically-inspired Coating on Titanium Improves Joint Replacements

July 2, 2008 -- Research at the Georgia Institute of Technology shows that coating a titanium implant with a new biologically inspired material enhances tissue healing, improves bone growth around the implant and strengthens the attachment and integration of the implant to the bone.

Magnetic Control: Tongue Drive System Allows Individuals with Disabilities to Operate Powered Wheelchairs and Computers

June 30, 2008 -- A new assistive technology allows individuals with disabilities to operate a computer, control a powered wheelchair and interact with their environments simply by moving their tongues. The Tongue Drive system, developed by engineers at the Georgia Institute of Technology, could help individuals with severe disabilities lead more independent lives.

Detecting Bioterrorism Agents: Ultraviolet Avalanche Photodiodes Demonstrate High Optical Gains

June 27, 2008 -- Researchers have shown that a new class of ultraviolet photodiode could help meet the U.S. military's pressing requirement for compact, reliable and cost-effective sensors to detect anthrax and other bioterrorism agents in the air.

Rapid Study: Automated Microfluidic Device Dramatically Reduces Time to Screen Worms and Other Small Organisms for Genetic Studies

June 23, 2008 -- Genetic studies on small organisms such as worms and flies can now be done more quickly using a new microfluidic device developed by engineers at the Georgia Institute of Technology. The new "lab-on-a-chip" can automatically position, image, determine the phenotype of and sort small animals, such as the worm Caenorhabditis elegans that is commonly used for biological studies.

Mimicking the Brain: Georgia Tech Wins Contract for Neuromorphic Research on Next-Generation Threat Warning Binoculars

June 20, 2008 -- The Georgia Institute of Technology has received a contract to help develop “intelligent binoculars” that mimic the low-level image processing done by the human brain. Called the Cognitive Technology Threat Warning System (CT2WS), the device is expected to be far more capable than portable visual threat-warning equipment currently used by the U.S. military.

Life Extension: Georgia Tech Research Institute (GTRI) Receives $4 Million to Redesign Modules for Air Traffic Control Radios

June 16, 2008 -- The Georgia Tech Research Institute (GTRI) has received a $4 million contract from the U.S. Air Force to redesign critical modules used in thousands of air traffic control radios. The redesign should help keep the radios on the job until newer designs can replace them.

Fuel Efficiency: Rising Diesel Prices Create Renewed Interest in Fuel-Saving Technologies Developed for Heavy Trucks

June 11, 2008 -- Diesel fuel prices approaching $5 a gallon – and the resulting economic impact on products transported by truck – have created renewed interest in fuel-saving technologies developed during the past decade at the Georgia Tech Research Institute (GTRI).

Missed Vaccinations: New Tool Creates Personalized Catch-Up Immunization Schedules for Missed Childhood Vaccinations

May 20, 2008 -- A new downloadable software tool will help pediatricians, parents and other health care professionals determine how to adjust complex childhood immunization schedules when one or more vaccine doses aren't received at the proper time.

Fast as a Femtosecond: New Technique Measures Ultrashort Laser Pulses at Focus

May 8, 2008 -- Lasers that emit ultrashort pulses of light are used for numerous applications, but the quality of the results is limited by distortions caused by lenses and other optical components that are part of the experimental instrumentation. Researchers have developed a system that tells researchers what types of aberrations are present, which allows them to create the desired pulse at the focus that's free of distortions.

Antenna Power: RFID Testbed Logs Many Tags and Rapidly Assesses New Antenna Designs

May 5, 2008 -- Researchers have designed a system capable of simultaneously measuring hundreds of radio frequency identification (RFID) tags and rapidly testing new RFID tag prototypes. This testbed allows researchers to measure the signal strength of tags hidden behind other tags and to rapidly test unique antenna configurations and multiple antennas without actually constructing new tags for each experiment.
