Magnetic Fluids Deliver Better Speaker Sound Quality
Posted in Articles, Electronics, Joining & Assembly on Wednesday, 01 April 2015
NASA’s liquid magnetization technology helps Sony increase sound amplitude while reducing distortion. In the early 1960s, NASA scientists were trying to move fuel into an engine without the benefit of gravity. A scientist at Lewis Research Center (now Glenn Research Center) came up with the idea to magnetize the liquid with extremely fine particles of iron oxide. That way, fuel could be drawn into the engine using magnetic force.

Thermal Management Solutions for Medical Electronics
Posted in Features, Electronics, Thermal Management on Wednesday, 01 April 2015
Electronic devices used in the medical industry have thermal management needs similar to those in other fields. Their electronics must stay cool enough to run continuously and correctly within their operating temperature range. Sound thermal management allows excess heat to be efficiently moved, spread, and dissipated. The result is improved system reliability and service life while, in many cases, it also helps designers reduce device package size, weight, energy consumption, and noise.

Linear Motors
Posted in Products, Electronics, Motors & Drives on Wednesday, 01 April 2015
Heidenhain (Schaumburg, IL) offers ETEL ILF and ILM series ironless high-speed linear motors for use in the semiconductor and electronics industry. The motors utilize an ironfree coil design for zero-attraction force between the carriage and the magnetic way. The ILF is a smallersized motor for very high dynamic and low-moving mass applications; the ILM is a more powerful version of the ILF, and has an option to be air-cooled to increase continuous force output. The ironless motors come in a variety of lengths and heights with different degrees of force, and share the same profile so that one is interchangeable with the other. The motors can reach speeds of up to 20 m/s and peak force of up to 2,500 N. They are designed for direct drive applications and offer no backlash, fewer parts, and require no maintenance.

DOEs Rescue Questionable Medical Electronics PCBs
Posted in Features, Board-Level Electronics, Electronic Components, Electronics on Sunday, 01 March 2015
Board cleaning is perhaps one of the most overlooked aspects of printed circuit board (PCB) assembly. But savvy medical electronics original equipment manufacturers (OEMs) have a keen sense of the importance it plays to ensure their products are free of miniscule flaws, defects, debris, and dust. In special cases, critical examinations must be performed to assure the correct cleaning solvents and processes are implemented to avoid damaging contaminants.

Self-Powered Intelligent Keyboard Could Provide Additional Security
Posted in News, Board-Level Electronics, Computers, Electronic Components, Electronics, Power Management, Energy Harvesting on Wednesday, 18 February 2015
By analyzing such parameters as the force applied by key presses and the time interval between them, a new self-powered, non-mechanical, intelligent keyboard could provide a stronger layer of security for computer users. The self-powered device generates electricity when a user’s fingertips contact the multi-layer plastic materials that make up the device.
