Gait Analysis Based on Inertial and Magnetic Sensors

Motion analysis often is based on stereophotogrammetry, which estimates the three-dimensional coordinates of points on an object by measurements made in two or more photographic images taken from different positions. While it provides very useful and detailed information about walking, the technique’s full capability of quantitative analysis of movement often is not used.

Sensors Enable Precise Mounting of X-Ray Telescope Assembly

NASA’s newest orbital X-ray telescope technology uses highperformance capacitive displacement sensors from Lion Precision. The sensors, capable of resolving position to less than 10 nanometers, are used during the mounting of over 10,000 thin glass mirrors into the telescope’s “lens.” Each mirror is about the size of a sheet of paper and only four times thicker. Achieving the required optical specifications for the telescope requires that each of the mirrors be mounted into position with better than 1 μm of accuracy. The mirrors must be able to hold this positional and angular accuracy during launch and deployment in space.

Simulations Prepare Curiosity Rover for Touchdown on Mars

Using MSC Software’s Adams multibody dynamics software, NASA’s Jet Propulsion Laboratory (JPL) engineers simulated the final sky crane landing sequence of the Curiosity Mars rover. The sky crane landing sequence required the rover to transform from its stowed flight configuration to landing configuration while being lowered to Mars, wheels-down, from the descent stage.

Light-Control Systems Help NASA Go ‘Net Zero’

The Propellants North Administrative and Maintenance Facility at Kennedy Space Center, located in Cape Canaveral, FL, achieves net-zero energy use. To offset the costs of electricity provided by a local utility, the center powers itself with renewable resources. The new facility is NASA’s first carbonneutral one, which means it is engineered to release no greenhouse gas emissions during renovation or operation.

Sensors Monitor Curiosity’s Drilling Arm

With the successful landing last August, NASA’s Curiosity rover is maneuvering the surface of Mars, analyzing samples of soil. Two sensors were developed by FUTEK for Curiosity. The first is a cryogenic multi-axial load and torsion sensor responsible for monitoring the rover’s drilling arm and its robotic maneuvers as it retrieves sediments for analysis.

Image Sensors Enable Curiosity to Capture High-Definition Images From Mars

The Mars Science Laboratory rover, Curiosity, is designed to assess whether Mars ever had an environment able to support life by deploying the most advanced set of scientific instruments ever sent to the planet. As part of that instrument suite, all four science cameras on the rover are designed using image sensors from Truesense Imaging to capture high-resolution color images of the planet.

Thermoelectric Cooler Helps Maintain Curiosity’s Temperature

The first spectrometer data from the Mars Rover Curiosity has made its way back to Earth, analyzing the plasma light captured during laser excitation of rocks and soil on the planet’s surface. Solid-state thermoelectric technology was used to cool the ChemCam (Chemistry Camera) CCD sensors. Maintaining temperature is critical for successful operation, and the Thermoelectric Assembly (TEA) provided a reliable cooling solution.
