'Tech Tidbit' – Wi-Fi Hotspots to be Installed in Public Transportation Systems
A company named Veniam has announced that with the help of True Ventures, it has raised about $4.9 million dollars for a project that will turn buses into Wi-Fi hotspots. This technology has already been introduced in the public bus system in Portugal and the company noted that about 75 percent of passengers use the new technology. With the new capital raised for this project, … [Read more...]
New Bill Rids Electronic Devices of FCC Label
President Obama has just signed the E-Label Act into law. With this new act, the FCC required label that is typically found on the back of electronic devices will not be required to be placed directly on devices. The FCC will now be required to post the label information online. “The bill applies to devices with integrated displays — smart phones, tablets, TVs — and directs … [Read more...]
‘Selfie Sticks’ Reportedly Interfere with Electronic Devices
A popular device in South Korea known as the ‘Selfie Stick,’ an extendable rods that allow users to take ‘selfies’ by using a remote trigger on cell phones through Bluetooth, reportedly interfere with other electronic devices that are using the same radio frequency, such as medical equipment. The government believes this radio interference can become dangerous in many … [Read more...]
Mechanical Vibrations in Environment Aid in Generating Electricity
A group of research scientists at the VTT Technical Research Centre of Finland announced they have found a new way to generate electricity. This method involves harvesting energy from vibrations in the environment and converting these vibrations into electricity. This was accomplished by connecting the bodies to an external circuit. The researchers generated this energy by … [Read more...]

MIT Researchers Develop Power-conserving Chip for Smartphones
Researchers from Eta Devices at MIT have developed a power-conserving chip believed to increase battery life in smartphones. The technology will allow batteries to last twice as long and work to conserve energy in cell towers. Batteries drain so quickly because power amplifiers typically stay at maximum voltage at all times, even when devices are not being used. The new chip … [Read more...]
Researchers Announce Development of Lighter, Cheaper Radio Wave Circulator
A research group from the Cockrell School of Engineering at The University of Texas at Austin has developed a smaller, lighter and cheaper radio wave circulator for wireless devices. Researchers believe this device could transform telecommunications. Typically, radio wave devices are produced of magnetic materials, which are usually heavy, expensive and large. The circulator … [Read more...]
New Amplifier Meets Automotive Radar Pulse Test Standards
MILMEGA has introduced its new high power, dual-band amplifier, the AS0104-700/300. “In conjunction with a new lensed horn package, this amplifier exceeds the requirements of automotive radar pulse test standards,” according to the company. This amplifiers’ test levels are usually 600 V/m and it operates in frequency ranges from 1 GHz to 4 GHz. … [Read more...]
