We propose to develop Co-located Triple Band Quantum Well Infrared Photodetectors (QWIP) Arrays. The innovative features are: Co-located Triple Band Structure The detection of short waveband (0.7-2.micro.m) midwaveband (3-5.micro.m) and long waveband (8-13.micro.m) signals takes in the same pixel (Co-located pixel). Simultaneous Detection of 3-Color Signals The design is such that detection of 3- ...

Cost effective technologies exist for the design and production of high frequency, brushless rotary servo motors for use in Navy designed and maintained underwater systems. This solicitation presents an opportunity to replace existing technology with state of the art, AIREX designed brushless motor technology and AIREX designed automated manufacturing processes. This proposal introduces Nav ...

Integrate emerging technologies of combination electromagnetic motor bearings, fault tolerant design and vibration isolation into a single, compact spherical actuator design. The resulting technology will provide low weight, reliable, two rotational and three translational motion control of sensitive payloads, and graceful degradation in system performance via fault tolerant control.

This Small Business Innovation Research Phase I program will determine the practicality of increasing the second harmonic (SH) output of frequency doubling devices by at least 5 times current gutput powers. Altos has demonstrated in preliminary experiments have a 2 times to 3 times increase in SH output by creating thermal gradients across the waveguide structures used to frequency double the lase ...

Anholt Technologies proposes to develop a low cost replacement aircraft Idoor. Preliminary analysis indicates Anholt Technologies' design, using Cpultruded stiffeners, flat panels and advanced adhesion techniques Jpossesses the required structural strength at a significantly reduced end Iitem cost. Anholt Technologies proposes to design, fabricate and test a Frepresentative stiffened structu ...

We propose exploratory development of new epitaxial growth technologies for low-defect GiN epitaxial structures and surrogate substrates. A significant feature of our approach is epitaxial latval overgrowth for "defect filtering." We present arguments that such epitaxial lateral overgrowth will lead to GaN material of unprecedented quality with respect to defects, stress, and purity. In the Phase ...

High performance electronics is in ever increasing demand across a wide variety of platforms ranging from personal computers to military and commercial aircraft. It is now possible to design and implement significant system functionality by hybrid integration of several ICs (even dozens) on a single substrate in a single package. The savings in weight, size, and total power dissipation are subs ...

Malaria infects over 200 million people and is responsible for 2 million deaths annually. Flow Inc. has developed diagnostic procedures based upon the fact that the parasite contains an enzyme lactate dehydrogenase (pLDH) (US patent 5,124,141). Recently, Flow Inc. has increased the sensitivity of its diagnostic procedures to detect 50 parasites/ul with the use of monoclonal antibodies (US Patent ...

A fast-pulsed (3-15ns FWHM) high-current (>500A) driver for high power diode lasers or laser arrays is proposed. Present high-current diode drivers typically use MOSFET switches to modulate the current. It is difficult to achieve very fast pulses with such devices because the inherent capacitance of the gate electrode cannot be charged and discharged quickly. Lower current, but faster diode driver ...

Navy aircraft, subjected to large takeoff and landing accelerations, need stiff avionics mounts for these operations. During flight, these stiff mounts fail to isolate flight vibrations well. A mounting system which switches from stiff to soft is proposed. Specifically, the E2C has problems with the vibration isolation of its avionics. The current system is designed for catapults and traps, n ...
