Active Devices proposes an innovation for energy harvesting using piezoelectric based approaches to extract energy from mechanical vibrations. This innovation consists of a piezoelectric element for energy transduction, rectifier circuits for extraction, and storage devices to store power for use by other devices. Ideal models predict that a 1" x1" x.010" piezoelectric wafer undergoing moderate ...

THE USE OF MULTIPLE SENSORS FOR ELECTRONIC SIGNAL UNDERSTANDING HAS IMPORTANT ADVANTAGES. MULTIPLE VIEWING ANGLES CAN PROVIDE MULTIPLE DIRECTION FINDING, MULTIPLE DOPPLER MEASUREMENTS FOR TARGET VELOCITY DETERMINATION, ROBUSTNESS AGAINST TERRAIN MASKING/SPOOFING, ETC. ALTHOUGH THE DATA FROM MULTIPLE SENSORS CAN BE SENT TO A CENTRAL SITE FOR PROCESSING, A DISTRIBUTED ELECTRONIC SIGNAL UNDERSTANDING ...

CARBON-CARBON COMPOSITES ARE INCREASINGLY BEING EMPLOYED IN ADVANCED DOD SYSTEMS. THE LENGTH AND COMPLEXITY OF THE MANUFACTURING PROCESS OF THESE COMPONENTS TEND TO MAKE THE PARTS COSTLY AND THE YIELDS LESS THAN OPTIMAL. AN ONGOING DARPA PROGRAM AIMS AT DEVELOPIG AN INTELLIGENT CONTROL SYSTEM WHICH INTEGRATES PROCESS MODELING, OPERATOR KNOWLEDGE, AND IN-PROCESS SENSORS TO IMPROVE THE RELIABILITY, ...

Micro Aerial Vehicle (¿AVs) will open up a wide range of new missions for the US Armed Forces, but also present a new set of technical challenges. The power and propulsion system will have a significant impact on the ultimate capabilities and range of missions of ¿AVs. While advanced battery technology can provide good propulsion performance for ¿AVs, miniature internal combustion engines can ...

Standoff detection of chemical and biological agent clouds is extremely important for the protection of US armed forces. We propose a system that will successfully perform stand off detection of both chemical and biological agents using a unique combination of advanced technologies. An imaging Fourier Transform Spectrometer (FTS) will perform the remote detection of chemical agents from an Unman ...

The emergence of compact products employing mixed technologies, such as personal digital assistants, wireless communicators and sensor systems, is creating a host of new needs in electronics packaging. These products are driven by small size, light weight, high-operating frequencies, unique micro-to-macro interfacing and low-cost. There is a need for a simplified and reliable process for direct ...

The technical objective of this project is the preliminary design of a small, low power, low cost packet radio wireless inventory (WI) transmitter which can be affixed to or embedded in individual inventory items or groups of smaller, less expensive items to provide tracking and inventory capabilities well beyond those now available. Two key features should be present in any comprehensive solutio ...

THE OBJECTIVE OF THIS RESEARCH IS TO DEMONSTRATE THE FEASIBILITY OF FUSING DATA OBTAINED SIMULTANEOUSLY FROM VISIBLE, INFRARED AND RADAR SENSORS, TO PROVIDE A HERETOFORE UNOBTAINABLE SURVEILLANCE CAPABILITY.THE DIFFICULTIES ASSOCAITED WITH SENSOR FUSION WHICH WILL BE ADDRESSEDINCLUDE THE DIFFERENT FIELDS OF VIEW, DIFFERENT MEASUREMENTS, DIFFERENT RESOLUTIONS, AND DIFFERENT POSITIONS AND VELOCITIES ...
