I heard a few bits and pieces about detecting gravitational waves. And the engineering is phenomenal. Gravity waves are measured by movement of suspended test masses, which are 40kg blocks of sapphire polished (to 250pm (=0.25nm)) to have mirror ends so they can be sensed by laser (I have no idea how laser sensing works when …
ADI adds processors to SHARC
ADI has added ADSP-SC57x and ADSP-2157x processors to its series of single-chip multicore SHARC processors. The devices advance the audio experience by enabling superior sound quality and more cost-effective and reliable audio systems. The new processor platform meets automotive temperature ranges without the need for costly, bulky heat sinks or fans, which saves space in …
PC and tablet units to drop 2%
The market for PCs and tablets will fall 2% this year following the 8% fall last year, says IC Insights. The markets for PCs and tablets continue to fall as more users delay replacement purchases and increase their reliance on smartphones for mobile-computing applications and access to the Internet. Worldwide shipments of PCs and tablets …
E-nose sniffs opportunity for health monitoring
As high-speed electronics replaces micromachines and chemicals, the electronic nose (e-nose) could get cheaper. Aimed at health monitoring through breath analysis, the e-nose has been designed at the University of Texas Dallas and performs ‘rotational spectroscopy’ at over 200GHz using a 65nm CMOS chips. “There have been many efforts to build an electronic nose,” said …

LoRaWAN brings IoT to Rome
Rome-based telecoms operator Unidata has adopted the LoRaWAN technology platform to deploy a low power, wide area network (LPWAN) in Italy. This follows news that Orange is deploying LoRa wide area wireless networks for smart cities in France. Unidata will also promote the IoT wireless technology with a demonstration lab in Rome LoRa technology supplied …
Bluetooth 5 standard promises to quadruple range, doubles speed
The next version of Bluetooth has been announced. As well as increasing the range and speed of transmissions, the next release – dubbed simply Bluetooth 5 – will also increase its broadcast messaging capabilities, for beacon operation and location services. The Bluetooth SIG promises Bluetooth 5 will quadruple its range to up to around 400m …

GPUs bring scalable processing to machine vision
The industry should machine vision technology more user-friendly because this cutting-edge field has dramatic and positive potential for embedded applications, writes Stephen Turnbull. At its core, machine vision is simply leveraging the information available in an image to make a decision about what to do next with the object in the image. A simple pass/fail …
Metasurface converts sunlight to heat for electron emission
Researchers from the Universities of Bristol and Exeter have created a metasurface that strongly absorbs light across the solar spectrum but minimises emission of thermal radiation. It uses uses amorphous carbon as an inter-layer between thin gold films with the upper film patterned with a 2D periodic array using focused ion beam etching. Gold is a first step, …
