Migrating Medical Devices to Multicore

July 13, 2011 7:04 am | by Justin Moon | Comments

As medical devices become more complex and offer increasingly sophisticated user interfaces and capabilities, these devices are inevitably moving to multicore processing. Today, ultrasound, MRI, CT, PET, and digital X-ray systems all imply multicore processing. It is not a question of if, but of when. In addition to all the other challenges they must face, medical device manufacturers must ensure that their multicore systems obtain FDA and other relevant certifications. This requirement has made many wary of multicore systems, concerned that their complexity might jeopardize certification. OS characteristics and features that can facilitate migration to multicore systems, as well as the question of validating multicore systems for certification are discussed.

High Precision Pressure Sensors in CPAP Respiratory Therapy Equipment

July 11, 2011 12:41 pm | by Dr. Adriano Pittarelli | Comments

Continuous Positive Airway Pressure (CPAP) machines are used to treat sleep apnea, a disorder that restricts breathing, and potentially causes stress to both the heart and circulatory system. Sensortechnics’ HDI and HCE series pressure sensors monitor the instantaneous pressure at the output of the machine and inside the breathing mask, increasing accuracy and sensitivity for individual CPAP users.

Metal Injection Molding Technology Creates High-Complexity, Low-Cost Components

July 11, 2011 10:13 am | by Tai Chee Keong | Comments

Metal injection molding (MIM) is a metal processing method that has become a beneficial manufacturing technology for the medical device industry, as it can produce complex-shaped, high-density, and high-performance metal parts at a low cost. Designers and engineers in the medical devices field are able to compare MIM to traditional machining techniques in the small parts arena.

Vision System Enables First Automated Learning and Testing Chamber with Real-Time Feedback

July 11, 2011 7:19 am | by Mark W. Smithers | Comments

A new method in examining test subject behavior has been developed by the Tufts Center for Regenerative and Developmental Biology partnering with Wireless Techniques. Given that manual methods performed by human researchers can be inaccurate, expensive, and time-consuming, the new automated learning and testing chamber can instead analyze the behavior of small animals on a 24/7 basis, with several experiments running at the same time. As a result, greater insight will be achieved in the area of learning and memory.

Protecting Your Inventions

July 7, 2011 12:43 pm | by Edward M. Weisz | Comments

 For engineers and designers of medical devices, familiarity with U.S. patent rights is necessary to protect inventions. Before filing an application, it is important to distinguish "prior-art" from "novel" inventions.

Optimizing Power in Portable Medical Applications

July 7, 2011 10:49 am | by Ken Marasco | Analog Devices, Inc. | Comments

Designing portable medical devices offers a multitude of challenges, from space constraints to interference issues to ergonomic concerns.
