Pin Fin Heat Sinks: A Sharper Way to Keep Medical Electronics Cool

March 31, 2010 5:42 am | by Barry Dagan, Cool Innovations, www.coolinnovations.com | Comments

Electronic medical systems have become substantially more sophisticated and powerful in recent years. As a result, the majority of these systems contain large arrays of power hungry electronic components that require high-performance heat sinks to prevent them from overheating and being damaged or destroyed.

Simplify USB Isolation in Medical Applications

March 31, 2010 5:10 am | by Mark Cantrell, Analog Devices, Inc., www.analog.com | Comments

The personal computer (PC), currently the standard information-processing device for office and home use, communicates with most peripherals using the universal serial bus (USB). Standardization, cost, and the availability of software and development tools have made the PC very attractive as a host-processor platform for medical and industrial applications...

New high-reliability contact system facilitates automated assembly

March 17, 2010 9:43 am | by Dave Humphreys, Product Manager, Harwin Inc | Comments

There are many applications whose operating environments demand the use of an interconnect system with a high-reliability contact. If equipment is to be used where high shock and vibration or extremes of temperature are experienced, connectors based on a standard contact will not be reliable or rugged enough to guarantee signal integrity.

Static Power Path Management (SPPM) to Provide an Effective Handheld Battery Charger Solution

March 12, 2010 10:44 am | by Chuck Wong and Haitao Hu, Intersil Corporation | Comments

Handheld electronic devices -- regardless of what they are used for or who manufactures them -- share one common denominator: a re-chargeable battery and, in most cases, a built-in charger circuit. When an external power source such as an AC adapter or a USB port is attached at the input terminal, the charger circuit will re-charge the battery.

Design Tips Save MCU Power

March 11, 2010 4:11 am | by Jon Titus, Senior Technical Editor | Comments

Microcontrollers offer engineers a variety of power-saving techniques. But using them effectively requires careful attention to tradeoffs in software and hardware at the start of a project. "Engineers must partition their application so they have a rough idea how long their microcontroller will stay in a sleep mode or in an active mode," said Mike Salas...

Get Rolling with Efficient Motor-Control Designs

March 11, 2010 3:58 am | by Jon Titus, Senior Technical Editor | Comments

To find out more about the state of motor-control design in embedded systems, I recently talked with three engineers at Texas Instruments who work with motor-related hardware and software. "Motor control looks simple to start but it covers many disciplines so it's almost impossible to have one designer do everything," noted Miroslav Oljaca...
