Scientists at Natcore Technology Inc using simple liquid bath processes, have created a black surface on a silicon wafer with an average reflectance in the visible and near-infrared region of the solar spectrum of 0.3%, making it the "blackest" silicon solar cell surface ever recorded. Compared with standard production cells now available, this represents a tenfold reduction in reflectance over that portion of the spectrum, which is the source of about 80% of the usable power that can be drawn from sunlight.
Hitting the friendly skies doesn’t necessarily mean you can’t make a mobile phone call — at least if you’re flying on one of Virgin’s new Airbus A330 planes. The airline plans to make in-flight calling available first on its flight from London to New York. By the end of the year, in-flight calling will be available on 17 planes and at least 10 routes.
The last time your doctor asked how much you exercise, did you tell the truth? Do you even really know the truth—not just how many visits to the gym you’ve made this month, but how many hours you sit or how many calories you burn in a day? What if your doctor had already received the information from a tiny device built into your cellphone, wallet, or undershirt? Sonny Vu believes a device like this could fundamentally change health care.
German designers placed a high-tech, sensor-equipped chair in the middle of a palazzo in Milan last month to record stress points on the backsides of thousands of people. The goal? To determine how to design a lightweight and efficient chair that’s sturdy enough to support a wide variety of users. When someone sat in the chair, monitors recorded data and processed it with an “algorithm that determines the most structurally efficient version of the chair,” according to the blog Co.
AWR Corporation once again takes a leadership position at the International Microwave Symposium (IMS) 2012 with a full slate of AWR 2011 software demonstrations, MicroApps presentations and panel, and its renowned Customer Appreciation Party. IMS 2012 takes place from June 17 to 22 in Montréal, Canada.
AXSEM produces a wide range of RF transceivers/receivers/transmitters which are commonly used in the bands below 1 GHz. AXSEM transceivers are known for excellent sensitivity, and very efficient power amplifiers. Typical sensitivities are in the range of -110 dBm to -126 dBm for 1.2 kbps (narrow-band or general-purpose).
Fifty one doctorate students from 12 countries will receive sponsorships to attend the IEEE MTT-S 2012 International Microwave Symposium (IMS2012) June 17-22, 2012 in Montréal. The program is part of a new initiative established and sponsored by the IEEE MTT-S Administrative Committee (ADCOM) specifically targeted toward students who have not previously attended IMS to increase their education in RF and microwave engineering.
Linx Technologies has started shipping the product lines it acquired from Radiotronix. The first products shipped in limited quantities are the TRM-915-DTS (formerly the Wi.232DTS-R), TRM-868-EUR (formerly the Wi.232EUR-R) and the TRM-915-R250 (formerly the Wi.232FHSS-250-R). In late May, Linx will start shipping the DP1203 modules as well as recertified versions of the DTS, EUR and R250 modules.
It’s surprising to hear that there’s still any debate as to whether companies should allow employees to use their personal mobile devices at work. It’s particularly perplexing when IT leaders are the ones who reject the idea. That’s because the statistics are overwhelmingly on the side of bringing your own devices to work, also known as BYOD.
Infinite Power Solutions, Inc. (IPS) announced that it has successfullycompleted a $10M Series D financing. The funds will be used to expand IPS’ manufacturing capacity in response to growing customer demand, to complete the build out of its global sales channels and to further support advanced research and development of its eco-friendly THINERGY® solid-state rechargeable Micro-Energy Cell (MEC) products.
A fleet of 100 floating robots took a trip down the Sacramento River today (Wednesday, May 9) in a field test organized by engineers at the University of California, Berkeley. The smartphone-equipped floating robots demonstrated the next generation of water monitoring technology, promising to transform the way government agencies monitor one of the state’s most precious resources.
The Microwave Application Seminars (MicroApps) are scheduled for the Palais des congrès de Montréal (Montréal Convention Center) June 19-21, 2012, as part of IEEE-IMS/MTT-S. MicroApps are a series of concise “application note” technical presentations given by exhibitors that are distinct and separate yet complementary to the IEEE technical sessions.
The development of next-generation mobile devices is facing many challenges, not the least of which is a growing scarcity of spectrum and a variety of mobile access technologies worldwide. Currently deployed cellular standards include GSM, WDCMA, HSPA, CDMA, and TD-SCDMA, and their evolutions will merge into the long term evolution (LTE) standard.
Break your iPhone in this case, and you’ll get a new one for free. Sounds like a pretty good deal, right? Meet Cellhelmet , a new protective iPhone case from a company called Cellpig. Originally started as a Kickstarter project, the cases recently went into production and are now available for retail sale.
TAU research finds that smart phone users develop new concepts of privacy in public spaces With endless applications, high-speed wireless Internet access, and free messaging services, smart phones have revolutionized the way we communicate. But at what cost? According to researchers at Tel Aviv University, the smart phone is challenging traditional conceptions of privacy, especially in the public sphere.
