The widespread use of communication devices and radar systems has made our society increasingly vulnerable to disruptive, high-power, short pulse electromagnetic interference (EMI) and high power microwaves (HPM). Significant advances in devices thatproduce these high-power, short pulses have been made in the US and abroad in the past few decades. As a result, the need for devices that can prote ...

The objective of this proposed project is to develop innovative structural health monitoring (SHM) technologies for application to composite structures for unmanned air vehicle (UAV) platforms. Composites can incur invisible damage from impacts, loadingabrasion, operator abuse, or neglect that if unchecked may lead to lower structural reliability, higher life-cycle costs, and loss in operational c ...

Bonded repair is a preferred technique for repairing localized damage in aircraft structures that can provide an efficient method for restoring the ultimate load capability of the structure. However, the effectiveness of a bonded repair depends heavilyupon the integrity of the bonding interface between the repair patch and the host structure. Currently there are few inspection methods available to ...

Bonded repair is a preferred technique for repairing localized damage in aircraft structures like Apache, Chinook and Comanche that can efficiently restore the ultimate load capability of the structure. However, the effectiveness of the repair depends uponthe integrity of the bonding interface between the repair patch and the host structure. Currently there are no inspection methods that can provi ...

DESCRIPTION (provided by applicant): World-wide public health surveys point to an increased global health burden for serious psychiatric disorders, particularly depression. Indeed, by 2020 it is expected that depression may be the second most serious medical condition with respect to global disease burden. It is clear that more effective pharmacotherapies are needed in treating depressive illn ...

DESCRIPTION (provided by applicant): Marine natural products are diverse in chemical structure and have great biological activities, especially anticancer activities. However, developing these compounds into clinical drugs has been hindered by their limited supply. Acera Biosciences, Inc. has developed a strategy to produce these compounds in fermentation. The proposed research project focuses ...

ACIT will design and demonstrate a remotely addressed crack/flaw detection system for composite materials. It will consist of a passive embedded sensor and a handheld portable detector, operating on the principle of the coupling of the LC tank circuit withthe behavior of a strain sensitive resistor. This system uses well known principles of an electronic circuit with carefully balanced forces of ...

DESCRIPTION (provided by applicant): Spinal cord injury (SCI) inflicts trauma to the cells and tissues of the central nervous system and causes a severe and debilitating condition in the individual. Following SCI, limited regeneration of injured neurons results in permanent disability characterized by some loss of sensation, paralysis and autonomic dysfunction. One reason that neurons fail to rege ...

Acoustech plans a two-year effort aimed at evaluating acoustic dyadic sensors for prospective use in directional sonobuoys utilized by the U. S. Navy. The chief sonobuoys targeted in this study are the AN/SSQ-53 DIFAR, AN/SSQ-77 VLAD, and AN/SSQ-62 DICASSunits. The DIFAR and VLAD buoys are passive devices that have a bandwidth of 5 - 2400 Hz, whereas the DICASS buoy is an active device that has ...

This SBIR Phase II research project strives to develop an Advanced Ultrasonic Beamformer that is unparalleled in its scalability and signal processing features. The ultrasonic beamformer architecture will be unique in its breadth of features. The architecture was developed as the superset of features across several fields including medical imaging, medical therapy, bone density measurement, vascul ...
