Evaluations by the Army staff at theU.S. Army Aeromedical Research Laboratory has… More

Active Signal Technologies proposes a thoroughly planned systematic development effort to produce a system that will meet the requirements of rugged operational monitoring to provide continuous electrocardiogram (ECG) and ventilation data on activelydeployed personnel. The program starts with a… More

DESCRIPTION (provided by applicant): With over 1.5 million persons suffering head injury annually in the U.S., and approximately 50,000 dying from these injuries, a need exists for early direct assessment of brain injury. Currently, injuries must be inferred from Glascow Coma Scores (GCS), low blood… More

Active Signal Technologies and Alfred University have brought together a broad-based industrial consortium to rapidly advance the development and commercialization of bismuth sodium titanate (BNT), a novel high performance capacitor material for use in both high-temperature and high-field… More

Active Signal Technologies and Moog propose to demonstrate a solid state pulse width modulated pilot stage for a servo valve enabled by single crystal PMN-PT.

Active Signal Technologies proposes to further develop and field-test its innovative hand-held Brain Trauma Assessment System (BTAS) with the objective of equipping EMS providers to directly measure brain pathology with sufficient sensitivity to confidently triage patients. With current field… More

The current tested and proven LBVDS system is limited in the platforms that can host it due to the large volume and weight requirements of the system. Active Signal Technologies proposes to retain the high power density features of the system, but modify it to retain as much performance as feasible… More

Active Signal, Moog, and Cornell University propose to develop and demonstrate a full-scale, benchtop-integrated, high-speed digital servovalve for use in adaptive structural control schemes that employ distributed actuation. Today's servovalves are expensive and low bandwidth because the mechanism… More

DESCRIPTION (provided by applicant): Currently almost half of all trauma mortality is directly or indirectly attributable to hemorrhagic shock, accounting for more than 50,000 deaths yearly in the U.S. and hundreds of billions of dollars in economic costs. Active Signal Technologies proposes to… More

Pneumothorax is a serious and potentially fatal warfighter injury that is difficult to diagnose in the high noise environment of the battlefield. Diagnostic methods beyond percussion, ineffective in the presence of high ambient noise, include large systems unsuitable for the first responders, such… More

Aeromedical evacuation (AE) involves prolonged transport of injured warfighters at risk for clinical deterioration under austere medical conditions. Because of their injuries they have a high potential for progression of recognized and/or occult additional injuries leading to acute instability… More

With the advent of the CCATTs a need exists for monitoring not only the vital sign information generated by a Propaq monitor but for additional hemodynamic and neurologic data to complement the Propaq data, especially in the event that the patient becomes destabilized during transport. Following… More

The present proposal is focused on developing novel methods to counteract excessive heat build-up in underwater sonar projectors. Building on over 25 years of experience in the design of Navy sonar devices and thermal management applied to high power density transducers and smart material… More

Active Signal Technologies, in collaboration with Novacap and Alfred University, will advance the development of two bismuth sodium titanate (NBT) ceramic materials with very promising dielectric properties across the temperature range -55oC to 300oC. The work will include enhanced formulation… More

Given the critical need for early detection of TBI and the potentially associated increase in ICP a requirement exists for a system capable of detecting elevated ICP and TBI, especially cerebrovascular status. The requirement is for a combination small, portable, robust fieldable system, and this… More
