Battery Safety: Do We Need New Regulations? stars

Even months later there's been no official report from Samsung on what caused the issues they were having with the Galaxy Note 7 batteries catching fire and exploding. However, a company by the name of Instrumental, which is a manufacturing tech company, has suggested that the reason for the very dangerous flaw was that there was no space allowed for swelling in the design of the battery. This suggestion has led some to consider whether or not safer standards and regulations on cell phones and battery designs need to be put into place.

Suspicious of the reported reason for the flaw, which was that there was an issue with one of the parts of the battery, Instrumental entirely deconstructed a Galaxy Note 7. In doing so, they were able to conclude that the phone’s rather aggressive design led to the battery explosions. As noted in a blog entry, Anna Shedletsky had this to say, “What we found was surprising: The design can compress the battery even during normal operation,” Shedletsky is Instrumental’s CEO, and founder.

Intel Atom Processor E3900 Series: Enabling Next Generator of Smart and Connectied IoT Devices stars

New Processor Series Moves Computing Power Nearer to Sensor, Alleviating Need to Push All Processing to Data Center

The Internet of Things (IoT) is linking billions of smart and connected devices to each other, creating a wave of change in how we live and work. The number of connected machines is expected to dramatically increase – by 2020, 50 billion devices (Cisco IBSG) will create 44 zettabytes (of 44 trillion gigabytes) of data annually, and will require much more processing power at the edge, and in the fog to network in order to maintain viability.

To support these experiences, today at IoT Solutions World Congress, Intel is announcing the latest generation of the Intel® Atom™ processors for IoT applications. The new Intel Atom processor E3900 series is designed from the ground up to support the rapid development and the growing complexity of IoT businesses. The result is a processor exceptionally capable of delivering on performance, processing and scalability.

Allegro Microsystems, LLC Introduces New Dual Full-Bridge PWM Motor Driver IC

Two Drivers in One Package Share Charge Pump Components to Save PCB Space

Allegro MicroSystems, LLC announces a new 40 V dual full-bridge driver capable of driving two DC motors with outputs rated up to 3.2 A. Allegro’s A5995 device includes fixed off-time pulse-width modulation (PWM) regulators for current control. Each DC motor can be controlled in forward, reverse, coast and brake modes with industry standard PHASE, ENABLE inputs. Fast or slow PWM current decay is selected via the MODE input. This new device is targeted at the consumer, industrial and office automation markets with end applications that include, laser, inkjet and label printers, copiers, vending, robot vacuums, and ATM machines.

STMicroelectronics Reveals High-Efficiency Wireless Battery-Charging Chipset for Smaller, Simpler, Sealed Wearables

A miniaturized wireless battery-charging chipset from STMicroelectronics saves space, simplifies enclosure design and sealing, and accelerates time to market for ultra-compact sports wearables, wellness monitors, medical sensors, and remote controllers. The combination of ST’s STWBC-WA charging-transmitter controller and STWLC04 wireless battery-charger receiver enables power transfers up to 1W with smaller coils than any other chipsets in the market: just 11mm diameter coils on the receive side and 20mm for the transmitter allow tinier, slimmer form factors. Power-transfer capability can be increased to 3W by using larger coils and a full-bridge circuit on the transmitter side. Eliminating any need for a conventional charging connector simplifies enclosure design and eases sealing to prevent contamination by dirt or moisture.
