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 ...

Herein ACX proposes a damage detection system based on ACX's QuickPack+ technology to combine piezoelectric actuators and sensors in a robust, easily mounted transducer package. The QuickPack encapsulates a piezoceramic with insulating flex circuit material and a simple connector. The transducer package will be bonded via a low-melting-point thermoplastic adhesive to ensure removability. The t ...

Significant deficiencies exist in the laser source technology for IRCM, specifically in the limited pulse rep-rate capability, limited average power output and capability to be transitioned to military environments. We propose a novel tandem OPO concept that uses two noncritical phasematched OPO's in KTA and AgGaSe(2) to generate the desired three output wavelength bands simultaneously. This con ...

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 ...

Explosion bonding of dissimilar materials has been performed since the 1960s on a commercial basis. However, titanium and ultra high hardness steel is not currently fabricated. This research will develop baseline explosion bonding parameters for titanium and medium carbon alloy steel in the annealed condition and susequent parameters for heat treating the steel to the desired hardness. This wor ...

Two major objectives of the U.S. Army is to increase power density and reduce heat rejection. Reducing airflow requirements of the deisel engine will contribute toward both of these objectives. Reducing air-fuel ratio requirements is one of the major cost effective approaches available for significantly increasing power output and reducing heat rejection in today's power output diesel engine. Po ...

The primary roadblock to the success of the high output Low Heat Rejection (LHR) diesel engine requiring little or no water cooling is the lack of effective liquid lubrication where target top ring reversal (TRR) temperatures between the cylinder liner and piston ring approach 1000 degrees F. Adiabatics, Inc. has developed a Thermo-sealed plasma sprayed Fe2O3 tribological coating which provides e ...

The topic presented in this proposal has direct application to the development of non-lethal devices capable of temporarily incapacitating personnel, controlling crowds, immobilizing small vehicles, and other applications where a controlled amount of acoustic c energy needs to be delivered a a distance. The proposed effort would determine the characteristic acoustic waveforms and amplitudes gener ...

The XA2 gasoline burner is widely used by the military to meet a variety of food preparation and heating requirements in the field. Because of the trend toward an single-fuel Army vehicle fleet and away from gasoline as a general purpose fuel, a diesel/JPS fueled burner is sorely needed. A recently developed catalytic vapor generator together with the proposed metal-hydride preheater should prov ...
