Astronauts, pilots, air traffic controllers, truck drivers, shift workers, and mountain climbers have something in common: All are at risk for impaired cognitive abilities due to stress or sleep deprivation. Whether in space or on Earth, stress and sleep loss can cause a reduction in certain cognitive abilities, such as working memory, reaction time, and problem solving. Because mission safety and success depend on being able to think clearly and function well, NASA began exploring a small, portable way for astronauts to monitor themselves and their cognitive fitness while in space, especially on future missions to Mars that will require extended periods in stressful environments.

Once considered a medical miracle, today’s coronary stent installations are now viewed as low-risk and commonplace procedures. In the U.S. alone, more than one million patients with heart disease receive stent implants every year.

Medical device design presents specific challenges for finite element analysis (FEA) engineers, who are tasked with simulating the mechanical behavior of medical devices or their components under a variety of conditions. These simulations help designers optimize the device and/or its component design prior to prototyping and physical testing.

JRI Maxant (Paris, France) offers the Mini SPY RF® data logger for cold-chain monitoring in medical applications. The device communicates in RF (50 to 60 m) and can be programmed remotely. Data are uploaded automatically via USB. The solution allows a network of independent recorders and bidirectional communication between recorders and the PC. It enables wireless communication with SIRIUS software and can be adapted to any mobile chamber to allow for real-time alarm, remote or local.

On July 5, 1997, a small robot emerged from its lander like an insect from an egg, crawling out onto the rocky surface of Mars. About the size of a child’s wagon, NASA’s Sojourner robot was the first successful rover mission to the Red Planet. For 83 Martian days, typically about 40 minutes longer than Earth days, Sojourner — largely remote controlled by NASA operators on Earth — transmitted photos and data.

This system can integrate with devices such as blood pressure meters and electrocardiograms.

The Wireless Patient Monitoring System deploys the Zigbee standard to create a Personal Area Network (a wireless network with a coverage area of around 10 m) that is capable of integrating into the same wireless network used by monitoring systems such as an electrocardiogram, pulse oxymeter, blood pressure sensor, and glucometer. The patient monitor also includes a gateway device for data encapsulation and transmission to the back-end systems via Ethernet, WiFi, and GSM/GPRS/UMTS connections. This gateway device also encompasses a Java applet for data presentation over an LCD touchscreen. For increased integration and interoperability features, the system also supports Bluetooth connectivity. The system supports up to 4 devices transmitting at the same time, and is powered with a rechargeable battery.
