This article addresses the impact of material choice on heat sink performance. First, we evaluate different materials using mechanical samples and a research quality wind tunnel. This testing compares a constant heat sink geometry made from copper, aluminum, and graphite foam.
There is a lot of talk about going “green” lately, and while it is noble, timely and responsible to save the environment from excessive green house gases, in these tough economic times, it can be equally as responsible to lower energy and power costs.
As a result of the Comcast Corp. v. Federal Communications Commission (FCC) court decision, Internet service providers (ISPs) are no longer constrained from slowing or blocking different types of content or access to sites that offer content that conflicts with the providers’ interests.
Are you a “Themimech” engineer? If not now, you might be soon! As the rising frequencies of many applications are now forcing engineers to be aware of and plan for issues related to rising frequencies in electronic devices and systems, they are now required to participate...
With continued pressure for broader 3G coverage for smart phones, increased Internet connection for Wi-Fi and WiMAX, and the imminent introduction of 4G/LTE systems, design activity for digital communication RF components has never been greater.
Hardware virtualization, and the hypervisors that enable it, have become a hot topic in the embedded space. But while virtualization opens up new possibilities for system architects and designers, it also poses new challenges, especially when used with real-time applications.
Designing Custom, Low-Cost Instrumentation for Test and Measurement Using Off-the-Shelf FPGA ModulesApril 29, 2010 11:36 am | by Jake Janovetz, Opal Kelly | Comments
Designing for industrial applications presents many challenges, but it also allows an engineer to be creative, spread her wings, and explore new technologies to solve the task at hand. Field-Programmable Gate Arrays (FPGAs) and, in particular, commercial off-the-shelf (COTS) FPGA modules can be just the ticket to attack industrial applications that used to be a much more difficult challenge.
Industrial applications, such as home and commercial building automation, data loggers, point-of-sale terminals and cash registers, in-house displays for energy metering, alarm systems and medical equipment are starting to join the “smart” revolution currently enjoyed by portable media player and smartphone markets.
Monitoring the condition of large industrial machinery provides long term benefits in terms of lower production cost, reduced equipment down time, improved reliability, and increased safety. Industrial manufacturers face a constant battle in keeping production equipment operational.
What future technologies will reduce healthcare costs?
Is breadboarding dead?
There seems to be no end to the demand of higher data rate applications and performance requirements as the number of new mobile devices continues to increase dramatically. The usage of mobile devices has evolved from voice only to multimedia messaging, downloading emails, web browsing, online gaming, video calls, social networking etc.
A pop musician recently reminded me that hit songs aren’t only catchy tunes; they are also a barometer of culture. I never expected to refer to Lady Gaga with anything other than casual references to her music or her edgy style (I’ve heard it called “21st-century Madonna), but one of her recent songs gave me some pause.
In March the Associated Press ran a story about security vulnerabilities in smart meters based on the research of InGuardians, Inc. The article highlighted the Achilles heel of any secure wireless system; the inadequate safeguarding of the security keys themselves.
LCD displays are widely used in cell phones, personal media players, internet tablet PCs, laptops, and large-screen TV sets. These displays account for a major part of the power consumed by these devices. For example, a mobile phone screen may consume upwards of 40% of the system power, while in a large-screen TV, the display may consume 70% or more of the system power.
