What’s the best way to advance alternative energy research? With government grants, free market solutions, or something else?
While a student at Susquehanna University for the past 3 years I have often had reservations regarding my decision to major in creative writing. The inevitable question ‘What am I going to do with my degree?’ has been on my mind more intensely as I approach my senior year.
A company called Uni-Pixel Displays has developed a novel display technology that they call “Time Multiplexed Optical Shutter” or TMOS. This uses a light guide with a special film suspended above its surface. An electrical charge draws the film down into contact with the light guide...
“Do you own your books?” sounds like a stupid question, doesn’t it? It’s like asking “do you own your socks?” Yet the recent actions by Amazon to reclaim books literally from their owner’s hands have demonstrated that in the digital economy, it isn’t a stupid question at all. We are giving up our ownership of information for temporary ethereal possession, and are at the mercy of those who “rent” that content to us.
Technology is driven by many factors, and the reinvention of existing technology products to new higher levels of performance requires innovations in materials and science. Critical components in the design of portable electronics, batteries, in the eyes of many, have not kept pace with innovations in their electronic counterparts. Is it time for the reinvention of one of electrochemistry’s oldest technologies to fulfill the needs of a new power market
Recent years have seen what can only be described as a wave of hyper-development in web technology. Concurrently, the ubiquitous Internet is quickly becoming the backbone of our communications infrastructure. Enter the web-enabled sensor. The marriage of common sensing technologies with the power of the Internet offers dramatic benefits for companies looking to remotely monitor levels or other parameters.
Each new generation of automotive and industrial designs have been faced with an increasing demand for precision control and diagnostic capabilities, as well as for reliability and safety features. Achieving these new features often requires precision current sensing, and as result, the demand for precision high-side current sense amplifiers has steadily increased in recent years. The applications for high-side current sense amplifiers
In our solid state society today, daily advances in technology have set the standard in many applications to that of excellence when compared to only a few years ago. This new standard of living has benefited today’s consumer in many ways that were only dreamt of years ago. Whether it is driver assistance controls that provide increased safety and convenience for your drive to work
The principal factors that affect data acquisition systems are: speed, accuracy, power dissipation, package size, and component cost, with varying factors becoming critical depending upon the application. This article shows how a single op amp can be used to drive the analog-to-digital converter (ADC) in an 8-channel data-acquisition system, reducing the cost and size of the overall system.
America finds itself at a juncture of many roads, with no clear map on which way to turn. The role of government, health care, energy, race, and disruptive technology have presented us with a myriad of choice on which road to take to the future. The important thing to remember is that we are all in the same boat together.
Time Domain Reflectometry (TDR) is a measurement of the impedance of a transmission line using the reflected energy of a pulse sent down that transmission line. As a pulse is sent down a transmission line, it travels at the speed of light for the media it is in (typically, 60% to 80% of the speed of light in free space). As the pulse arrives at an impedance, mismatch energy is reflected back to the pulse source and arrives at a time
Technology developments that reduce complexity and enhance usability are always a welcome addition to rugged applications, since fewer parts means improved reliability. This truth is especially evidenced by the increasing availability of stand-alone rugged boxes. The development of stand-alone rugged boxes has provided a singular computing solution for rugged applications where reliable high performance computing is a must. Previously, rugged computing devices were dispersed among several different computing units
The wonderful communications technology infrastructure we have created has given everyone the power to communicate with anyone else on the planet at a moments notice with images, text, voice, and video. All of the focus is on the software tools such as Twitter, Facebook, or YouTube that are at the forefront of the societal sea change, but it is the newly-risen global information network that is the real hero.
Hardware design in high performance applications such as networking, wireless/RF transmission, broadcast video and test and measurement is becoming increasingly complex as hardware designers grapple with the need to support a growing number of standards, protocols, and specifications within a single hardware design. A few examples illustrate this trend.
