ABJ Integration Technologies, Inc. proposes to model a vertically optically interconnected stack of silicon integrated circuits to form a three dimensional system. This 3D system will utilize through-substrate optoelectronic communication to which the package and silicon are optically transparent. System optimization for user specifications will include materials and components such as emitters ...

Unsteady buffet forces excite the vertical tails of aircraft flying at high angles of attack and cause excessive stress and vibration in the tail structure. This results in increased fatigue which ultimately reduces aircraft life. It has been shown by ACX that distributed piezoceramics can significantly reduce the buffet loads on the tail structure of an F/A-18. ACX proposes to develop a simila ...

ACX proposes an innovative new process for the manufacture of smart structures using a High Velocity Oxy-Fuel (HVOF) thermal spray process. This simple, multi-step process will be capable of depositing electroded piezoceramic coatings. The coatings will be poled while still hot, reducing poling times and voltages while increasing poling efficiency. Process times will be extremely short. The pr ...

ACX proposes to develop durable and reliable conformal geometry actuator packages. These packages will have the ability to operate as linear actuators for motion control applications as well as to conform to structures with curved surfaces for applications requiring induced strain actuation. These packages provide a protective skin offering electrical isolation, and provide a means for integration ...

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 objective of the proposed project is to develop innovative new analytical instrumentation and methodology capable of performing fully automated, non-destructive analysis of semiconductor sensor elements and arrays locate on three inch diameter wafers. The instrumentation would be capable of analyzing II-VI compounds and alloys, particularly HgCdTe. The methodology would employ state-of-the-a ...

Although technologies derived under the Integrated High Performance Turbine Engine Technology (IHPTET) initiative should result in higher performance of gas turbine engines, the durability of engine components continues to be one of the most important design issues which impacts their affordability and robustness. It is currently very difficult to measure or predict the fatigue life of engine com ...

The ongoing explosion of microwave radar and communications systems calls for improvement in electronically scanned antennas (ESAs). However, current ESAs crafted from multiple individual elements are extremely expensive. Forming an antenna with integrated scanning and impedance matching elements on a single substrate using thin film technologies may decrease costs by up to two orders of magnitu ...

The III-V nitrides, (Al, In, Ga)N, are promising materials for high temperature, high power and high frequency devices due to the wide bandgaps, high electron saturation velocity and high electronic mobility transistor (HEMT) structures available in this alloy system. These devices would find wide-spread commercial use as power amplifiers in base station transmitters for personal communications ...
