Imaging Sensors Examine Evolution of Solar Activity and Space Weather

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

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.
