Unified Communications Grow into 2012 Earlier embraced as a future trend, unified communications (UC) continue to make inroads. Current trends are reported in the 2012 Unified Communications Survey conducted by Information Week. Companies and organizations that have deployed and utilized UC jumped from 30% in April 2010 to 36% now. Impressively, another 31% plan to deploy this communications venue within the next two years. Survey respondents comprise 71% from companies with 500 or more employees and the remainder from companies with 10,000 or more workers. Overall, the study concludes that businesses can do more with less by opting for UC, thanks to advances in technology. Take our brief readership survey now for a chance to win a $100 American Express gift card!   Acoustic Emission RNDT, Inc. Minimize Leakage Level and Noise in One Package Schuster Electronics, Inc. At RNDT, several conventional and modal AE systems, with the most advanced hardware and software available, provide our acoustic emission Level II and III technicians the tools to offer many production, in-service, and research related examinations. We can handle a variety of specialized AE examinations in both lab and field settings. Even if medical-grade certified, combining a filter and/or another power supply can cause your application to exceed the 300 microamps leakage limit. Schuster Electronics offers theCosel PMA Series, medical-grade AC-DC power supplies, with built-in dual-choke filter that minimizes both leakage and noise. It's like an AC line filter and power supply in one-package.

Speakers & Amplifiers . . . Learn More Intuitive Bluetooth Speaker with AM/FM Designers have created an intuitive Bluetooth speaker that's easy to use. To operate the cylindrically shaped Hidden Radio and Bluetooth Speaker, users simply twist the movable cap to turn it on and adjust the volume. Delivering a 30 hr battery life, this speaker is capable of 80 dB sound and incorporates an AM/FM radio plus a 3.5 mm audio jack. Mini Wireless Speakers Deliver the Features One of the latest Bluetooth speaker systems is Logitech's Mini Boomboxfeaturing backlit touch controls plus a microphone for use as a speakerphone. A USB-rechargeable battery delivers power for 10 hours, and a 3.5 mm jack provides support for additional devices. See it compared to the twice the price Jawbone Jambox. Acoustic Materials . . . Learn More Rubber Returns to the Road in Noise Barriers Disposing of used rubber vehicle tires continues to be a global environmental problem. Fortunately, the European Ekopan project has a workable solution: reusing recycled rubber from tires in roadway noise barriers. As it turns out, utilizing the porous material to partially replace raw materials in conventional barriers results in improved noise absorption and less weight than concrete alternatives. Piezoelectric Material for MEMS Expected to find application in sonar, ultrasonics, sensing, and energy harvesting, a new piezoelectric material delivers 2-4x the movement of predecessors. Developed by University of Wisconsin-Madison researchers, the PMN-PT material expands with greater force and yields stronger electrical signals (video). Described as a "much bigger bend for your buck," the high efficiency material is targeted for silicon microelectromechanical systems.   Overall Acoustic Level OROS Custom Sound-proofing and Acoustic Materials Merryweather Foam, Inc. The OROS Overall Acoustic is an optional NVGate plug-in for all OROS 3-Series Analyzers. With an OROS 3-Series you get a multi-channel analyzer, so why not turn your unit into a true multi-channel sound level meter. The OVA plug-in extends the analyzer capabilities to a comprehensive acoustic measurement system. Looking for a sound-absorption solution? Not sure what you need? You're not alone! Acoustical-absorption products are available in a range of mediums and designs that meet the specifications of engineers working in diverse industries. You may find that many commonly used sound absorbing products cost more than innovative, newcomer solutions. Signal Measurement & Processing . . . Learn More World's Fastest Internet Connection For the world's fastest Internet connection at 120 Gbps, Cisco and Telia put together a 300 km long connection utilizing a fiber network, CRS-3 routers, and other special equipment from the two companies. In theory, 750,000 users could stream music at the same time and download a complete movie in 0.047 seconds. The feat set a record for network capacity utilization and more. Silencing 'Growling' Servos Servomotor instability can often cause "growling" at higher frequencies — a common problem that can be solved by reducing the gain on the speed controller. Marcus Schick, Siemens motion control business, relates how to eliminate the undesired growling noise of servo driveswithout adversely affecting performance and increasing position error. In brief, lower inertia ratios cut the probability that system resonances will become a problem. Mobile & Handheld Devices . . . Learn More Boosting Hard-to-Hear Sounds Modifying phones and other audio devices so that users can hear better by improving individual hearing-loss fingerprints goes far beyond just boosting the volume. One way to accomplish that is to create a standard sound-calibration test. Toward that end, ACEHearing is a new smartphone app that utilizes a simple test to tailor mobile device output to improve listeners' hearing. Do Workers Need a Quad-core Mobile Device? Nvidia's Tegra 3 quad-core processor boosts performance 5x overall and 3x graphically vs its predecessor. While business software runs reliably on dual core, this upgrade homes in on power consumption. For less demanding tasks, a fifth processor runs at 500 MHz with four main processors off. The net result is 61% less power consumption or a 12 hr battery life.   EEC Magnets and Assemblies ITAR/DFARS Compliant Electron Energy Corporation Waterproof Equipment Cases from Dayang Enclosures Ningbo Dayang Enclosures Co., Ltd. Electron Energy Corporation is anITAR/DFARS compliant developer and producer of custom rare earth permanent magnets, assemblies, and systems. Superior magnetic properties, ultra-high temperature tolerance, and excellent reliability make EEC magnets ideal for motors, actuators, and generators used in low volume high performance niche applications. Dayang Equipment Cases feature: molded in high-impact ABS. Dust-proof, water-proof, and airtight. With a valve that adjusts air pressure, an extendable handle, and wheels for a smooth ride. Strong polyurethane wheels with stainless steel bearings. Press and pull latches. Multilayer cubed foam bottom and a convoluted foam pad in the lid. Protection level: IP67. Careers & Commentary . . . Smartphone Spying or Not? When it comes to the legality of carriers monitoring 150 million smartphones, the jury is still out. Allegedly, virtually anything a smartphone user does is being monitored by software — unbeknownst to users. This includes keystrokes, numbers called, Web sites visited, location, searches, and more. The U.S. Senate will be investigating whether the Carrier IQ application is infringing on privacy or not. Diversions . . . Super Cool DIY Electronic Music Building your own mini electronic instruments and synthesizers sounds like quite an undertaking for even established audiophiles. Not! These credit-card sized devices — bass generators, drum machines, micro-synthesizers, and more — can be put together in two hours. As depicted in this video, a wireless network empowers all instruments to jam together. Photocells also allow reaction via light, for instance, controlling envelope, filter, and pitch of a drum machine. Share Your Thoughts . . . About This Month's Topic Sharing Electric Cars With noise characterized as the top city nuisance in Paris, the city has opted for self-service EVs that also reduce noise pollution. To what extent you think noise (or air) pollution will be impacted, and when?
