Summer is right around the corner. This means vacations, trips to the beach, and high temperatures. For myself, I’ve invested in a floppy straw sun hat to keep my body at a cool temperature, but what about my black, heat-absorbing cellphone? Cellphones have components for thermal management, such as heat sinks and special heat-sinking material, known as pyrolytic graphite sheets (PGS).
Voice and data communication systems rely on highly accurate data converter and clocking systems to acquire, convert and manage high-speed digital and analog signals. The level of timing accuracy directly determines the data transmitting capacity of these systems.
More than a billion Wi-Fi devices were shipped over the past year and the market is growing fast. These devices are destined not just for laptops, tablet PCs and mobile phones, but for all the everyday equipment used in homes, offices, public spots, and literally everywhere. Equipment like washing machines, refrigerators, energy meters, surveillance cameras, industrial robots, point-of-sale terminals, photo frames – a really long list – all coming together as the Internet of Things.
The success of new technologies that reduce energy consumption in buildings and homes has led to a burgeoning of wireless solutions aimed at simplifying how building automation solutions are installed. Among the building automation solutions available, some wireless devices stand out because they are powered by limitless sources of energy that are omnipresent in buildings.
With the increased demand of mobile video, mobile music, data, and the convergence of these services with social media platforms, the mobile phone market is growing rapidly. But the move toward these services leaves mobile carriers struggling with falling ARPU and the potential of being relegated to bit-pipe providers.
AT&T recently jolted its customer base by announcing price hikes on their smartphone and tablet data plans. The good news – customers under contract can keep their current pricing packages. The bad news – new customers will pay 33 percent more. AT&T’s tiered pricing model has spurred similar offerings from other carriers and it’s only a matter of time before other carriers raise their prices to offset data carrying costs and accommodate a growing smartphone customer base.
Recent developments have put into question the true capabilities and benefits of full-body scanners, the controversial devices that use what the Transportation Security Administration calls “advanced imaging technology.” One wonders if officials in Washington, having adamantly defended the scanners for years, might just be too stubborn to concede the equipment’s ineffectiveness.
For retailers – tablets equal gold. After entering the e-commerce space in the last years, and with the help of user-friendly mobile apps, retailers are pleased – and profitable. But this isn’t the only wireless technology that they’re (almost) smiling about. Mobile payments are developing in their favor, thanks to near field communication.
By Ali Sadri, President and Chairman of the WiGig Alliance, www.wirelessgigabitalliance.org The widespread availability and use of digital multimedia content has created a need for faster wireless connectivity that current commercial standards cannot support. This has driven demand for a single standard that can support advanced applications such as wireless display and docking.
EN-PTFE composite coating exhibits equivalent, or better, properties than cadmium and nickel-cadmium With the last remaining loopholes closing rapidly, the opportunity for connector manufacturers to find an optimum cadmium replacement is here. Even those that produce or distribute aerospace and military-grade connectors are under mounting pressure to meet the tightening requirements of the European RoHS directives, which are pushing towards elimination of cadmium altogether.
Tech industry writers and bloggers have been predicting a smaller-form tablet from Apple for over a year and a half—long before Tim Cook and company announced the latest full-sized, 9.7-inch “new iPad” early last month. As expected, in the weeks since the announcement rumor sites have continued to churn out hearsay articles detailing new specifications of this hypothetical, unconfirmed device.
Why the Battery State-of-charge cannot be measured accurately Measuring stored energy in an electrochemical device, such as a battery, is complex and state-of-charge (SoC) readings on a fuel gauge provide only a rough estimate. Users often compare battery SoC with the fuel gauge of a vehicle. Calculating fluid in a tank is simple because a liquid is a tangible entity; battery state-of-charge is not.

Introduction Wireless radio transmitters have evolved over the years from real IF (intermediate frequency) transmitters, to complex IF transmitters, to zero-IF transmitters. However, there are still limitations associated with these commonly used architectures. A newer approach, a direct RF radio transmitter, can overcome the limitations of traditional transmitters.
