Enabling Safe, Low-Temperature Operation in Batteries
Carnegie Mellon University’s Venkat Viswanathan and a graduate students Shashank Sripad and Dilip Krishnamurthy are working to improve the safety of lithium ion batteries, which are common in devices such as smartphones, hearing aids and digital cameras. Viswanathan, an assistant professor in mechanical engineering, researches how designing materials can create novel energy conversion and improve storage capabilities.…
Aperture Tuning for 5G Smartphones
Antenna efficiency plays a critical role in overall smartphone RF performance. However, current broad trends in RF requirements – especially the forthcoming transition to 5G – and in smartphone industrial design, mean that smartphones must fit more antennas into less space. As a result, antennas are shrinking in size, which reduces antenna efficiency. Without compensating…
FT: Huawei Cuts Meetings With US, Sends US Workers Home
BEIJING (AP) — The Financial Times reported Friday that tech giant Huawei has ordered its employees to cancel technical meetings with American contacts and has sent home numerous U.S. employees working at its Chinese headquarters. The moves come amid growing U.S.-China tensions over trade and technology in which Huawei has been a main target. The…
Sound Waves Bypass Visual Limitations to Recognize Human Activity
Video cameras continue to gain widespread use to monitor human activities for surveillance, health care, home use and more, but there are privacy and environmental limitations in how well they work. Acoustical waves, such as sounds and other forms of vibrations, are an alternative medium that may bypass those limitations. Unlike electromagnetic waves, such as those…
Japan Law Loosens Rules for Self-Driving Cars
Stuck in traffic on a Japanese highway? If you’re in a self-driving car you might be able to kick back with a sandwich and check your phone under new legislation in the country. The law, passed Tuesday and published on the lower house website, takes effect from next year ahead of the Tokyo Olympics and…
‘Neural Lander’ Uses AI to Land Drones Smoothly
Landing multi-rotor drones smoothly is difficult. Complex turbulence is created by the airflow from each rotor bouncing off the ground as the ground grows ever closer during a descent. This turbulence is not well understood nor is it easy to compensate for, particularly for autonomous drones. That is why takeoff and landing are often the…
A Step Toward Fully Electric Ferries
Hybrid and electric vessels are under the spotlight lately, thanks to intensified efforts to limit greenhouse gas emissions from global shipping, a significant source of CO2 and other pollutants. There are already several offerings of such green ships in Europe, and a Danish operator is ready to pave the way for the widespread use of fully…
Tech is Vital Element in Search for Missing Hawaii Woman
WAILUKU, Hawaii (AP) — Technology is becoming a vital element in the search for a woman who went missing in a rural Hawaii forest. Volunteers searching for 35-year-old Amanda Heller are employing GPS devices and computers with live feeds and real-time data from the parking lot of the Makawao Forest Reserve on Maui, The Maui…
Chinese Man Guilty of Defrauding Apple Out of 1,500 iPhones
SALEM, Ore. (AP) — Over the span of two years, a Chinese national in Oregon sent devices that looked like iPhones to Apple, saying they wouldn’t turn on and should be replaced under warranty. He didn’t just submit a couple of the devices — he delivered in person or shipped to Apple around 3,000 of…
