For decades, technology experts and home automation enthusiasts have been talking about and promising the emergence of the smart, connected home. They have foretold a home connected by multitude of sensors, monitoring applications such as HVAC, home security, and even the health of the inhabitants, and all controlled remotely over the web via a smartphone or a tablet.
In the semiconductor industry, precision testing is key to ensuring proper functionality and quality. Two types of testing are traditionally performed: 1) wafer testing 2) chip set testing Both types of tests require the use of relays with fast switching speed to carry various types of signals. Test boards are designed with as few as two relays or as many as several thousand per board.
Test and measurement starts with standards. You have to have standards for mass, distance, charge, and time (plus a few others) so all standards refer back to those fundamental unit standards. But you don't measure volts in units of amps, kilograms, meters, and seconds, that requires something more convenient (i.e. measuring volts in volts).
When it comes to power system design, there are many options to consider that affect efficiency, availability and scalability. In most cases availability and scalability are the primary considerations for data centers. The data center is directly dependent on the critical power system, and electrical disturbances can have disastrous consequences....
When technology experts talk about the “Internet of Things,” it’s not an understatement. The sheer number of connected devices is growing at an unprecedented rate. IDC estimates mobile devices will total 1,832.3 million units in 2013 while predicting the total mobile phone shipments will reach 2,281.4 million units worldwide in 2017.
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.
