Meet Eesha Kare, who invented a device that charges cell phone battery in under 30 seconds
Eesha Khare, 18, of Saratoga, Calif. received the Intel Foundation Young Scientist Award of $50,000. With the rapid adoption of portable electronics, Eesha recognized the crucial need for energy-efficient storage devices. She developed a tiny device that fits inside cell phone batteries, allowing them to fully charge within 20-30 seconds. Eesha’s invention also has potential applications for car batteries.
Yahoo has officially announced that it will acquire Tumblr in a $1.1 billion cash deal expected to close in the second half of the year, and will keep Tumblr’s David Karp on as CEO. “Per the agreement and our promise not to screw it up,” Yahoo says in its press release, “Tumblr will be independently operated as a separate business.” In one of its first acts of business, Yahoo has moved its official blog to yahoo.tumblr.com.
Amazon has just debuted its own virtual currency, Amazon Coins, allowing customers to pay for apps on its Amazon Appstore for Android, as well as some in-app items. Kindle Fire customers in the US are the first to get their hands on Amazon Coins, as the company is giving all of them $5-worth of the currency, or 500 coins. But anyone can head to the Amazon Coins page and purchase Coins for themselves.
The ever-expanding networks of sensors and other machine-to-machine devices on the “Internet of Things” are creating huge stores of data for everything from traffic and weather monitoring to health care and finance.
And there will only going be more of them. Sensors, for example, will play a key role in the Obama Administration’s recently released National Strategy for Civil Earth Observations, a plan to increase the efficiency and effectiveness Earth-observations. Along with other steps toward streamlining the efforts of the 11 agencies involved in the observations, it calls for extensive use of sensors in gathering the data.
Of course, having all that data is one thing. Making sense of it — quickly — is another. One key is the emerging Message Queuing Telemetry Transport (MQTT) protocol, a lightweight messaging transport for machine-to-machine communications that recently was proposed as an OASIS standard.
OASIS in March began the process “to define an open publish/subscribe protocol for telemetry messaging designed to be open, simple, lightweight and suited for use in constrained networks and multi-platform environments.” The protocol, which consumes little power, is designed to help sensors and other devices — which tend to be low-power and low-bandwidth — communicate reliably.
