Emerson Network Power (Carlsbad, CA) offers the NPS20-M series open-frame power supplies, feature a 2” × 4” footprint and a height of 1”. The series supports up to 25 W with convection cooling and up to 40 W with forced air cooling. Under normal operating conditions, the power supplies require less than 49 W of input power and consume less than 300 mW of power under no-load conditions. They have an average efficiency of 87 percent. Available in five models with outputs ranging from 5 V to 48 V, they accept a wide universal input voltage range of 90 to 264 Vac (127 to 300 Vdc). All models have ±20% user output voltage adjustment and remote sense. They deliver a demonstrated mean time between failures of more than 550,000 hours and feature built-in EMI filters (CISPR 22 Class B).

New Chips Could Replace Current Method of Testing Medical Devices
Posted in News, Electronics & Computers, Electronics, Sensors, Medical, Patient Monitoring, MDB on Monday, 25 October 2010
Princeton engineers have developed a sensor that may revolutionize how drugs and medical devices are tested for contamination, and in the process also help ensure the survival of two species of threatened animals. In the wild, the African clawed frog produces antibacterial peptides - small chains of amino acids - on its skin to protect it from infection. Princeton researchers have found a way to attach these peptides, which can be synthesized in the laboratory, to a small electronic chip that emits an electrical signal when exposed to harmful bacteria, including pathogenic E. coli and salmonella. "It's a robust, simple platform," said Michael McAlpine, an assistant professor of mechanical and aerospace engineering. "We think these chips could replace the current method of testing medical devices and drugs."

The Ins and Outs of Connectors in Medical Equipment
Posted in Electronics & Computers, Electronics, Mechanical Components, Medical, Patient Monitoring, Features, MDB on Wednesday, 01 September 2010
Medical equipment manufacturers are placing greater emphasis on higher resolution imaging, viewing, and displays in diagnostic equipment. As a result, EMI and RFI requirements are critical considerations when designing X-ray machines and ultrasound equipment. In addition to resolution requirements, diagnostic equipment is becoming increasingly portable, resulting in demands for smaller, lighter components that are still highly reliable. Because connectors are used extensively in medical diagnostic equipment, there are a number of design considerations manufacturers must implement to conform to these requirements. Materials and filtering of the connector play a key role in shielding to meet EMI/RFI requirements, while pin counts, pin spacing, and contact system design affect the size and life expectancy of the connector.
