Current sensing with 1MHz bandwidth and 1.2mΩ insertion resistance is claimed by Allegro MicroSystems for its latest Hall-based sensor. Response time for the ACS730, as it is to be called, is 210ns. Being Hall-based, the sensed current path is electrically isolated from the measurement circuit so the IC can sense high-side current without an additional isolation …
Rifle aimed at Snapdragon
Next week, Xiaomi is expected to announce its own ARM-based mobile processor called Rifle. Rifle is the answer to Qualcomm’s Snapdragon processor line but is not expected to be a rival to the upper echelons of the Snapdragon line-up. Not for a while anyway. The initial Rifle is expected to be targeted at the mid …
3D technique promises accurate multi-coloured mouldings
Need a multi-coloured prototype with complex curves? A new form of thermoforming is the answer, according to Swiss University ETH. In thermoforming, a plastic sheet is warmed to near melting point and sucked onto a mould – it is the technique used to make yoghurt pots. “The new method is a clever combination of established thermo-forming and software …
Researchers print THz lenses
Researchers in the US have used metamaterials and 3D printing to create lenses that work at terahertz frequencies. “Not only does it have better imaging capabilities than common lenses, but it opens the door for more advances in the mysterious realm of the terahertz,” said Northwestern University. Rather than use several lenses of different refractive index …
Samsung's Tarn reports progress in CSP LEDs and GaN-on-Si LEDs
General-illumination lighting products will emerge in the coming months that utilize Samsung chip-scale-package (CSP) LEDs while the company is now supplying LEDs for smartphone camera-flash applications based on silicon-substrate technology.
San Diego Region releases long-term water management strategy
Updated Urban Water Management Plan balances supplies and demands over two decades.
Water community celebrates Drinking Water Week
Professionals across North America kicked off Drinking Water Week today by highlighting the theme “Your Water – To Know It Is To Love It”.
Construction of Eagle Ford Water Gathering System begins
e gathering system and surrounding facilities (“EVX South Texas”) will be underpinned by a fee-based, 15-year agreement that includes a 72,000 acre dedication in La Salle, Frio, and Atascosa Counties,Texas.
The Knock On The Door
Another blow to the IoT is the US Supreme court’s decision that the police can search, via the internet, any computer within US jurisdiction. It is probably only a matter of time before our government passes a similar law. And, of course, the definition of what is within a country’s jurisdiction can be extended pretty …
Intel’s Mobile Dilemma
Has Intel given up on mobile processors? It’s long been urged by Wall Street that it should. This time last year J P Morgan said mobile processors were a “money pit” for Intel while Morgan Stanley said intel needed $8-10 billion of mobile revenues to break even which “seems unachievable.” Morgan Stanley estimated Intel’s mobile …
