Compact 6W DC/DC Converters

mbarnes — Fri, 17 May 2013 21:13:42 +0000

The MA600MHI series from MicroPower Direct is a family of compact, 6W DC/DC converters fully approved to both EN 60950 and EN 60601. They are specifically designed to meet the stringent isolation, reinforced insulation and low leakage requirements of medical grade equipment. Twelve models operate from wide 2:1 inputs of 9 to 18, 18 to 36, and 36 to 75 VDC, providing single and dual outputs of 5, 12, ±12, or ±15 VDC.

The STM32F401 is the entry-level microcontroller in STMicroelectronics’ high-performance STM32F4 series featuring the ARM Cortex-M4 32-bit/DSP core. While running at lower frequency than other STM32F4 devices, it balances performance, power consumption and integration and claims the lead in its class by offering 105DMIPS at 84MHz, 187µA/MHz active current, 11µA typical STOP current, and a rich set of integrated features.

Starter Kit Speeds Up Commissioning

With its new StarterKit, Nanotec Electronic (Medford, MA) is providing companies with a complete solution for choosing and commissioning the optimum drive. Various motor settings can easily be tested, and different operating modes such as open loop and closed loop can be compared. This speeds up the evaluation phase, and shortens the commissioning time.

The type of sensors that pick up the rhythm of a beating heart in implanted cardiac defibrillators and pacemakers are vulnerable to tampering, according to a new study conducted in controlled laboratory conditions.

Implantable defibrillators monitor the heart for irregular beating and, when necessary, administer an electric shock to bring it back into normal rhythm. Pacemakers use electrical pulses to continuously keep the heart in pace.

Nanotechnology Could Help Fight Diabetes

Injectable nanogel can monitor blood-sugar levels and secrete insulin when needed.

Injectable nanoparticles developed at MIT may someday eliminate the need for patients with Type 1 diabetes to constantly monitor their blood-sugar levels and inject themselves with insulin.

UT Arlington Physicist's Tool Has Potential for Brain Mapping

A new tool being developed by UT Arlington assistant professor of physics could help scientists map and track the interactions between neurons inside different areas of the brain.

New Study Recommends Using Active Videogaming ('Exergaming') to Improve Children's Health

sfenske — Fri, 17 May 2013 15:44:39 +0000

Levels of physical inactivity and obesity are very high in children, with fewer than 50% of primary school-aged boys and fewer than 28% of girls meeting the minimum levels of physical activity required to maintain health. Exergaming, using active console video games that track player movement to control the game (e.g., Xbox-Kinect, Wii), has become popular, and may provide an alternative form of exercise to counteract sedentary behaviors. In a study scheduled for publication in The Journal of Pediatrics, researchers studied the effects of exergaming on children.
