Measuring temperatures using infrared (IR) sensors without direct contact with an object, is the new paradigm in optimizing thermal monitoring and control. In this article we introduce the idea of this approach by taking advantage of new and very small IR temperature sensors available on the market.
Whether it’s a high-rise office tower or a manufacturing floor, Heating, Ventilation and Air Conditioning (HVAC) systems are designed for building occupants’ comfort. When systems operate at optimum levels, they’re energy efficient and go unnoticed. When they’re not, efficiency drops and complaints rise.
Perhaps no business service is more critical than telecommunications; reliability and quality of a phone system are absolute requirements. Over the past decade, internet-based VoIP (voice over internet protocol) has taken its place as a viable means of communication for individuals....
In the last few months I’ve been writing about various efforts of the government – both on the local and federal level – to leverage our consumer technologies to learn about our driving habits, cellular records, and, in the event of cyber attack, access to email records. Taken in totality, one could be highly suspicious that virtually anything and everything about our lives is accessible....
Two industry megatrends are reshaping the way we design and deploy networks and compute (i.e. datacenter servers). The first is Network Functions Virtualization (NFV) with the goal of moving functions such as content distribution, firewalls and base station controllers from proprietary hardware to standard, low cost servers.
One of the challenges of working with integrated circuits is as designers try to make ICs faster, the transistors become smaller and can’t handle as much voltage and the amount of variation grows. Plus, a single fault in the IC could mean a useless chip, bringing projects and products to sudden jarring halt.
The Society of Women Engineers, along with the American Society of Mechanical Engineers recently honored Noha S. El-Ghobashy with the Kenneth Andrew Roe Award. El-Ghobashy is an inspiring humanitarian working tirelessly to bring opportunities and advancement to underdeveloped nations.
A driving force in the current military environment is to keep legacy equipment operating longer or replace legacy systems with new ones that simulate or emulate one or more legacy systems. Replacements face the challenge of interfacing with disparate communication protocols and interfaces.
The popularity of touch screen technology, also referred to as ‘touch panel’ or ‘user interfaces’, has increased a great deal in the last few years. Integrating interfaces with LCD is becoming increasingly popular. It is estimated that touch screen revenue will reach $16 billion in 2012, and nearly double in six years, reaching $31.9 billion by 2018.
Aside from offering up the world’s least-appetizing pizza (protein cheese layer anyone?) and a way to eliminate illegal poaching, 3D printing might play a vital role in the future of the military. Though the technology is not nearly advanced enough to make a significant impact right now, the Navy is looking to 3D printing as a potential money saver for the future, according to an article published in the Armed Forces Journal.
Procuring military equipment has become an extremely difficult task. Not only is there constant pressure to reduce expenditure, but performance requirements are increasingly hard to define as armed forces face growing and unpredictable threats such as civilian groups and militias using improvised weapons and ad hoc methods.
The usual response to the idea of a “harsh environment” is to envision the salt spray of a drilling rig, dirt, grease or debris. But in today’s evolving world of “high tech,” the definition of harsh isn’t always what it used to be. An environment most people would consider far from harsh, almost sterile, can be extremely susceptible to contamination....
Many signal processing, analytical, and diagnostic instruments are utilizing Eurocard-based enclosures that are recessed. With higher signal frequencies and lots of cabling, the incentive to recess an enclosure continues to increase for many applications. There are many benefits to this type of design....
The Smart Grid is coming. It is needed in order to raise or lower prices for consumers depending on the time of day. It is needed to control consumer loads to better integrate intermittent alternative energy into the grid (industrial loads are already demand controlled by the grid operator depending on the type of service contract they have).
Through 2016, the home healthcare market is projected to grow at an annual rate of 7.7 percent. This projection underscores a significant trend: More patient treatments are shifting away from healthcare facilities into home environments as patients grapple with the rising costs of on-going healthcare treatment plans.
