The Visibility app uses a smartphone's camera, GPS, compass, and accelerometer to estimate air quality. Users take a photo of the sky, and the app analyzes it to determine pollutant content.
Researchers at UC San Diego developed a new chip prototype called GreenDroid, which uses dark silicon to improve performance through specialized processors. The prototype delivers improved efficiency by running heavily used code in Google's Android platform, resulting in up to 7.5 times increased efficiency compared to aggressive mobil...
Researchers warn that biometric logins may not be secure on the go due to mobile device limitations. Biometric technology uses fingerprints, voice recognition, or typing patterns for authentication.
A new initiative called Cell-All aims to equip cell phones with sensors capable of detecting deadly chemicals. The technology uses a chip costing less than a dollar and can alert the user and authorities in under 60 seconds, reducing false positives and improving response time.
The AFib Educator app and desktop widget provide detailed, animated diagrams of the human heart to help patients understand atrial fibrillation. Healthcare professionals can share resources with patients, including facts about signs, symptoms, prevalence, and risks, as well as links to additional information.
Rutgers University researchers have demonstrated a new security threat against smart phone users, showing how malware can eavesdrop on calls, track locations, and drain batteries. The study highlights the vulnerability of mobile operating systems to attacks similar to desktop computers.
Researchers developed an Android app called PowerTutor to help users compare the power consumption of different applications. The app provides real-time information on how phone components use power, enabling users to make informed decisions about their device's energy efficiency.
Researchers designed smartphone games and easy-to-use logging features to help elderly Chinese diabetics manage their health. Initial studies of the system, called CADA, show promising results, enabling diabetics to track vital information for better doctor-patient interaction.
Researchers have successfully coupled USB-based ultrasound probe technology with smartphones, enabling compact, mobile medical imaging devices. This innovation has far-reaching implications for global healthcare, particularly in developing countries where access to medical imaging is limited.
A new amplification technique using nonlinear oscillators can convert signals' trajectories into symbols for enhanced communication. This technique has the potential to improve communications for ships and other vehicles in remote locations.
Dennis L. Goeckel, an assistant professor of electrical engineering at the University of Massachusetts, has received a $200,000 grant from the National Science Foundation to continue his research on high-speed wireless communication. He uses mathematical models to optimize signals and improve reception quality.
Researchers at Virginia Tech have developed a safer wireless antenna design called Safetenna. Safetenna eliminates transmission in the direction where the signal would be blocked by the user's head, reducing harmful absorption of power by the body. The new technology demonstrates improved performance with no trade-off on safety.
