Using Surge Testers for Design Verification and Production Testing
Posted in Features, Electronic Components, Power Management, Power Supplies, FDA Compliance/Regulatory Affairs, Measuring Instruments, Monitoring on Sunday, 01 March 2015
Not only are medical devices expected to function as intended, they must meet ergonomic, safety, FDA and functional requirements. They must be designed to function in adverse environments; sometimes in the operating room; sometimes in an emergency vehicle for example. If a device is patient connected, it is also expected to function within proscribed parameters in the presence of a defibrillation pulse. These parameters differ depending on the type of device. All devices must pass an isolation test designed to ensure that the pulse will not affect the device’s signal input part/signal output part (SIP/SOP) ports; and effective with the Third Edition of IEC 60601-1, they must demonstrate that they absorb less than 10 percent of the defibrillation pulse. ECG monitoring equipment either for hospital (IEC 60601-2-27) or emergency use (IEC 60601-2-25) is additionally subject to performance requirements after a defibrillation pulse is applied.

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.

Automotive Circuit Protection Using High-Reliability TVS Diodes
Posted in Briefs, Power Management on Sunday, 01 February 2015
Diode technology eliminates transient surges and enhances vehicle safety. Littelfuse, Chicago, Illinois Designing automotive electronics presents numerous technical challenges, including the need to protect against electrical hazards. The three major sources of electrical hazards in automotive systems are electrostatic discharge (ESD), switching loads in power electronics circuits, and lightning. Overcoming these transient surges that can harm the vehicle’s electronics, whether under the hood or in the cabin, is one of the biggest obstacles of system design.

A Resistive, High-Voltage, Differential Input Interface in a 3.3-V BiCMOS 0.5-μm Process for Extreme Environments
Posted in Briefs, TSP, Power Management, Sensors on Sunday, 01 February 2015
NASA’s Jet Propulsion Laboratory, Pasadena, California Wide-temperature and extreme-environment electronics are crucial to future missions. These missions will not have the weight and power budget for heavy harnesses and large, inefficient warm boxes. In addition, extreme-environment electronics, by their inherent nature, allow operation next to sensors in the ambient environment, reducing noise and improving precision over the warm-box-based systems employed today.
