Imaging Sensors Examine Evolution of Solar Activity and Space Weather

e2v CCD203-82 charge-coupled device sensorse2v TechnologiesEssex, United Kingdom+44 (0)1245 493493

Six Charge-Coupled Device (CCD) imaging sensors have been incorporated in NASA’s Solar Dynamics Observatory (SDO) spacecraft, the first of NASA’s Living With a Star (LWS) programs to launch. The LWS programs are designed to study and understand the causes of solar variability and their impact on Earth and near-Earth space. In order to study the Sun on small scales of space and time, and in many wavelengths simultaneously, the SDO has three scientific instruments on board: the Atmospheric Imaging Assembly (AIA), the EUV Variability Experiment (EVE), and the Helioseismic and Magnetic Imager (HMI).

Control System Safely Moves a Robot During Invasive Neurosurgery

Robotic devices have been used in the medical industry for more than 40 years. Despite the advantages, researchers have faced unique challenges in developing effective, safe robotics applications for medical use. In contrast with industrial applications in which robots operate in work cells where human staff is not permitted to enter, robots in the medical field must operate in direct contact with the patient and medical staff; therefore, the safety requirements are considerably more complex and restrictive than in industrial situations.

Cockpit Vision System to Improve Pilot Safety

Inertial-Optical Head-Tracking System InterSense Billerica, MA 781-541-6330

Under NASA funding, InterSense is developing and testing an inertial-optical head-tracking system for commercial pilots. The company will work with a miniaturized inertial-optical tracker prototype integrated into a Head-Worn Display (HWD). The next phase involves testing and analysis of the system with flight tests in order to assess functionality and performance.

Optimizing the Interoperability of Military Satellite Communications

Satellite communications offer mobility and communications for military operations in remote locations where terrestrial-based connectivity is not available, or is too expensive. Unfortunately, satellite connectivity brings many challenges that can impair network performance in delivering mission-critical information and applications. High-latency transport and application protocol inefficiencies, adverse weather, and interference are just a few of the causes that slow the delivery of applications and limit the amount of traffic that can run over a satellite link. Compounding these problems is interoperability among disparate military networks that can jeopardize mission-critical communications.

Tunable Bandpass Filters

The ubiquitous techniques of fluorescence and Raman imaging and spectroscopy rely heavily on spectrally precise, high-quality and high-throughput optical filter technologies. As both fluorescence and Raman-based techniques move from traditional R&D-based environments into medical and clinical (diagnostic) settings, even higher demands are placed on system performance. Therefore, it is necessary to continue to improve system components and architectures to meet the demanding challenges often encountered in biological applications.

Software Improves Access to NASA Earth Models

Frontier Grid Platform for distributed computing Parabon Computation Reston, VA 703-689-9689

Access to complex climate modeling and simulation models from NASA’s Earth-observing satellites will be easier after development of a Web-based system from Parabon Computation. The company is working with NASA’s Goddard Space Flight Center (Greenbelt, MD) to help scientists access climate models. The models would be hosted as a Web service so users can access and run them in a Web browser, without the use of a local copy of the application.

Custom Assembly Helps Create Medical-Grade Saline in Space

BioConnect® bag and tubing assemblies Cole-Parmer Instrument Vernon Hills, IL 800-323-4340

BioConnect custom bag and tubing assemblies supplied the materials and services to catalyze the production of a prototype for the Intravenous Fluid Generation (IV Gen) technology demonstration on the International Space Station. Funded through NASA’s Human Research Program, a team from NASA’s Glenn Research Center (Cleveland, OH) and ZIN Technologies (Cleveland) seeks to produce medical-grade saline solution in a zero-gravity environment. If successful, the process solves the challenge of packing IV solution that expires during the shuttle cycle, and alleviates mass and volume storage constraints.

Camera/Robot System Increases Quality and Reduces Costs for Vehicle Component Supplier

The Piston Group (Redford, MI and Liberty, MO) builds cooling modules for seven different vehicles. These cooling modules are built on five different assembly lines, with each line building more than 50 different variants in sequence to the customer’s demand. Many different inspections need to be performed on each module, including verifying the build variation, checking electrical connections, and all dimensional requirements.

Data Management Speeds Up Simulation of Crash Test Dummy Models

The idea for the automotive crash test dummy first came to life in the 1950s when U.S. Air Force flight surgeon Col. John Stapp realized that more of his fighter pilots were dying in car crashes than from accidents in their hi-tech jet aircraft. The Stapp Car Crash Conferences started that decade and continue today as a venue to share information on the latest research and advancements for improving vehicle crashworthiness and occupant safety.
