Between 1990 and 2000, over 600,000 implantable cardiac pacemakers and cardioverter defibrillators were recalled. 41% of these devices were recalled due to device software issues. Software-related recalls are increasing with the growing complexity of medical device software, which is responsible for the life-critical operation with the organ. Currently, there are no formal methods to test and v...
The emergence of ignition device of semiconductor bridge provides a way to resolve the conflict between low energy and high promptness, reliability and safety of initiating explosive device. But with the rapid development of arms and ammunition, the higher demand of miniaturization for structure and volume in design of initiating explosive device is put forward based on high safety, reliability...
We present interference analysis from Non-communication device which is used in many applications such as factory, home and hospital into Global Positioning System (GPS) Service. GPS service is used to detect location for car driving and safety of life. Nowadays, non-communication devices are increased rapidly. Therefore, in case that noncommunication device and GPS receiver are operated in clo...
Cellular networks are evolving to an increasing number of applications ranging from simple voice calls to video streaming and data transfer. Recently, it has been suggested to extend theses networks to short range communications using device to device links. The aim of such type of operation is to alleviate the data traffic load on cellular networks, and also to provide an alternative option fo...
-A hardware and software design and development is described for a two-channel portable recording device specifically to collect the electroencephalogram (EEG). The application intended for this device was collection of EEG data from drivers, while driving under controlled conditions on closed roads or circuits. The monitoring of driver reactions may lead to a better understanding of driving ab...
BACKGROUND Machine learning methods may complement traditional analytic methods for medical device surveillance. METHODS AND RESULTS Using data from the National Cardiovascular Data Registry for implantable cardioverter-defibrillators (ICDs) linked to Medicare administrative claims for longitudinal follow-up, we applied three statistical approaches to safety-signal detection for commonly used...
The TUNA device is a unique system that uses radiofrequency energy to ablate the obstructing prostate adenoma. Although the clinical data are preliminary, they appear to provide improvement in symptom scores and peak flow rates, although somewhat less than TURP. A prospective, randomized trial comparing TUNA to TURP is under way, which should answer many of the questions regarding the safety an...
