V.Kadal Amutham, Reader: Already many countries are implementing mobile payment for ticketing in the bus / train and purchases at stores avoiding credit cards.Another possibility for this technology is as follows. The mobile phone will store any personal data like, size of cloth, preferred brand of many household items.
Should you use primary batteries or energy harvesting for your low power isolated from the grid application? Are primary batteries better or worse than energy harvesting? Can you use one or the other or do you need both? Neither? It is an interesting question depending on the application, the power required, and the costs involved.

The market for residential photovoltaic (PV) energy storage systems is expected to boom in the coming years, with cumulative installations amounting to 2.5 gigawatts (GW) by 2017, equivalent to the solar power that could be generated by more than 600,000 homes.
The Kineo1 from Farsens S.L., San Sebastián, Spain, is a battery-free RFID sensor tag capable of transmitting a unique identifier and the associated orientation data to a commercial EPC C1G2 reader without the need of a battery on the sensor tag. The Kineo1 tags can communicate to around 1.5 meters (5 feet)....
Measurement Specialties has expanded its line of pressure sensors with two compact, high-performance units for demanding industrial applications. The M7100 and U7100 feature high reliability at a low price point. The new IP67-rated pressure transducers withstand high vibrations as well as harsh conditions, such as dust particles, contaminated water and corrosive fluids, making them ideal for use in demanding engine, vehicle and industrial applications.
The biggest challenge is that LED chips are quickly approaching their theoretical limits for efficient light output. As they do, incremental improvements to the LED die are providing diminishing returns on investment. Fortunately, innovations in optical silicone packaging materials are introducing new, more cost-effective ways to enhance efficiency (lm/W), as well as cost (lm/$) and light density (lm/cm2).
Adeline Chan, product marketing manager, Cree, Inc.: LED technology has been evolving rapidly over the years. From a performance perspective, lumen output and efficacy numbers have been improving. Other “areas” of the LED technology have also progressed such as thermal properties, substrate materials, light distribution pattern,
When it comes to alternative energy, I have been a big fan of storage. Alternative energy will not be viable for large-scale power delivery to the grid without storage. My friend Clyde knows of my obsession with storage. He suggested I look into GE's new wind turbines that come with storage attached.
POSITAL-FRABA’s LINARIX linear position sensors have been added to the list of products referenced by the Rockwell Automation PartnerNetwork™. Through Encompass™ Product Partners, customers can quickly locate complementary products that best solve any application challenges.
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.
Yokogawa Corporation of America announced that it is now offering electric vehicle charging stations to employees at its Newnan, GA facility. ECOtality, Inc. – a leader in clean electric transportation and storage technologies– has installed two Blink Electric Vehicle (EV) charging stations at Yokogawa Newnan as part of its Electric Vehicle Project.
In this week's headlines: Drone It Yourself turns random objects into RC quadrotors: A Drone It Yourself project turns just about anything into a quadrotor drone with the addition of a few motors and a control unit. Twinkind 3D photo booth scans your body in a flash: A company called Twinkind in Hamburg, Germany is offering a 3D portrait service that creates your very own mini-me.
A few folks requested my presentation from out 10th anniversary open house. So, without much adieu, here it is. Download Top 10 traps 7-2013 Duane Benson 10 time 10 isn't necessarily equal to 10 times 10. Especially if you mix bases. -Duane Benson
A robotics team from the University of Queensland has created two versions of a single-use UAV. The unmanned aerial vehicles, which are usually associated with clandestine military operations, are both designed to relay environmental information.
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).
The solar-cell pushers have been touting for quite some time the fact that the costs of solar cells have now nearly reached capital-cost parity with other sources of electrical energy. Parity is assumed to be a dollar a peak watt of capacity or thereabouts. But is that really true?
Here at ECN we're always looking for what's going to change the world of electrical design. This month we're focusing on new material technology. From adhesives to thermal gap pad management, we want to know what's happening in your lab and on your benches!
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.
Nordson EFD has developed a non-contact dispense valve for precision jetting of low viscosity flux onto solar cell bus bars. Operating at speeds up to 500Hz/sec, the Square Wave 745NC valve meets the photovoltaic industry's need to deposit continuous lines of microdots on the solder-coated metal ribbons that connect adjoining PV wafers.
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....
