TDK-Lambda (San Diego, CA) has introduced the NVM175 series of medically approved AC-DC power supplies. Combining 4.5 kVac reinforced input to output isolation with dual input fusing and an output-to-ground isolation of 1500 Vac, the NVM175 meets UL/EN/IEC60601-1 and is suitable for use in BF (Body Floating) type medical applications (e.g. ultrasound, ECG, patient monitors, etc.) It offers a compact 5" × 3" footprint with less than 1U height (1.02" high component height), and universal AC input. It is rated at 180 W at 50 °C with user supplied air flow. Leakage current is 80 μA maximum with 120 Vac/60Hz input. Available with either 12 or 24 V output voltage (with 12V/0.2A standby), the NVM175 achieves up to 90% efficiency, less than 1 W standby power, and RoHs and REACH compliance. Standard features include a power good signal, remote on/off, remote sense, and protection from over-current, over-voltage, and over-temperature conditions.

Power-Assist Control Interface for Wheelchairs
Posted in Bio-Medical, Electronics & Computers, Electronics, Rehabilitation & Physical Therapy, Medical, Briefs, MDB on Saturday, 01 May 2010

This technology monitors input and effort, and instantly adapts the device to real-world conditions.

A computer-controlled, programmable control interface allows safe, intuitive manual control for motorized wheelchairs that operate in variable terrain. The key feature of this technology is its proprietary computer program that enables an operator to manage a load as if it were light and on a smooth level surface, no matter what the real-world load or grade is. Operation is completely intuitive and does not require manipulation of throttle and/or brakes.

Molded Interconnect Device Technology Enables Smaller Medical Devices
Posted in Electronics & Computers, Electronics, Manufacturing & Prototyping, Features, MDB on Monday, 01 March 2010
The need to minimize healthcare costs is creating greater demand for equipment that, among other things, improves and expands patient diagnostics, both inside and outside healthcare facilities. For example, portable medical instruments such as glucose meters, blood pressure monitors, and oxygen meters can be designed with communication capabilities to provide continuous information to caregivers almost anywhere. Smaller handheld devices can also improve various diagnostic procedures in dentistry and medical offices. In addition, these smaller portable devices can improve the quality of life for patients who use them. While such devices hold the promise of improved care at lower cost, they require advanced technologies that allow greater miniaturization to further improve portability and functionality.
