Researchers Create Lab-on-a-Chip for Quick Infection Testing

Infectious-Disease-Testing

All About Circuits – As the pandemic resurges in many parts of the world, researchers have found a way to bring the speed and accuracy of infection testing to mobile devices with a lab-on-a-chip.

A new lab-on-a-chip has been developed by researchers at Imperial College London who hope it can pave the way for low-cost portable diagnostic testing. The lab-on-a-chip (LoC) technology, known as TriSilix, is a “micro laboratory” that can reportedly perform a scaled-down version of the polymerase chain reaction (PCR) test on the spot, presenting its results in just a few minutes. PCR, which detects viruses and bacteria in biological samples, is usually performed in a laboratory, meaning that test results don’t become immediately available. 

Each LoC device contains a DNA sensor, temperature detector, and heater so that the testing process can be automated. According to the researchers’ published findings in Nature Communications, a standard smartphone battery is capable of powering up to 35 tests on a single charge.

What is the Z-Wave protocol?

Z-Wave-Technology

EE World – Smart homes need wireless connectivity, and Z-wave has emerged as the ultimate solution for home automation. The Z-wave protocol is a wireless, radio frequency protocol designed primarily for smart home networks. All the existing wireless communication protocols had one or the other problem. Bluetooth and Zigbee often shortfall of range while Wi-Fi poses its own limitations in a low-power ecosystem. Interoperability has been another major issue as popular wireless standards have different protocols and implementations for different applications. No one solution could cater to the requirements of an automated home. Z-wave is, now, the solution for all those lingering issues.

Z-wave devices are interoperable and can be easily accessed through the internet or a Z-wave gateway. With a range of around 40 meters, a Z-wave network limited to four hops can connect at most 232 devices. Irrespective of their make or application, all devices can have simultaneous two-way communication over the Z-wave network secured using AES. With sufficient range, optimum data speed, AES security, low-power wireless solution, and interoperable protocol, Z-wave is just perfect for home automation. There are now thousands of Z-wave products in the market, serving as intelligent devices for smart home ecosystems.

SambaNova Emerges From Stealth With Record-Breaking AI System

SambaNova-DataScale-AI

EE Times – SambaNova, one of the AI chip startup “unicorns,” has emerged from stealth mode after three years to announce its first product, a system-level AI accelerator for hyperscale and enterprise data centers and high performance computing (HPC) applications. SambaNova’s business model includes selling various configurations of the DataScale rack-based system, as well as renting them out for a monthly subscription in an offering the company calls “Dataflow-as-a-service”.

Founded in Palo Alto, California in 2017, SambaNova has been in stealth mode until now, though the company has released some details about its “software defined hardware” chip architecture. The startup has raised $456 million in three rounds of funding to date, and is reportedly valued at more than $2.5 billion.

DataScale is built on SambaNova’s Cardinal SN10 reconfigurable dataflow unit (RDU) chip. SambaNova still hasn’t given away much about this chip, with VP product Marshall Choy telling EE Times only that each chip offers “hundreds of teraflops and hundreds of megabytes of on-chip memory with direct access to terabytes of off-chip memories.” Choy argued that SambaNova’s customers, to an extent, do not care about the details of the chip; they are buying or renting the rack-based system which is SambaNova’s first product.
