A Fluid Preservation System (FPS) was developed to address NASA’s need for a way to preserve body fluids collected from astronauts during flight. Sample processing is done within the system container, and the samples are hermetically sealed in a small, convenient package. Blood sample collection has significant commercial demand in areas such as cancer research, and for certain assays and bio-indicators. This application also extends to veterinary analysis and widespread monitoring of livestock, as well as use by first responders during natural disasters. Find out more HERE.

A Robotic Titan to Build Rocket Parts

A titan resides at NASA’s Marshall Space Flight Center. One of the largest composites manufacturing robots created in America, it will help NASA build the biggest lightweight composite parts ever made for space vehicles. The robot will build structures larger than 26 feet in diameter, and is mounted on a 40-foot-long track.

Vest Warns Construction and Rescue Workers

Working at a construction site is loud, dirty, and often dangerous. Virginia Tech researchers have combined small radio sensors that construction workers can wear on or inside vests with connected vehicle technology that allows cars to “talk” to one another, roadside infrastructure, and personal electronics such as mobile phones.

Choosing the Right Potentiometer for Reliable Sensing

In today’s market, there are a variety of available types of position sensing systems. It is important to compare unique features to application needs in order to find the best fit. A potentiometer sensor is an electromechanical component that consists of a resistor where the voltage divider value can be measured at any position by means of sliding contacts between the applied voltage values. Physically, a potentiometer consists, at a minimum, of a resistance track, a collector track, and a sliding contact that can be moved along the resistance track by means of mechanics (Figure 1). The movement of the sliding contact can be rotatory (angle) or translational (path).
