Communication between soldiers on the battlefield is currently limited to voice and hand signaling. However, the realities of combat, including loud noises and visual obstructions, degrade these communications modalities. The U.S. Department of Defense is interested in the use of tactile human interfaces as a supplemental communications channel between soldiers. A field-deployed haptic communica ...

Laser diodes (LD) have many desirable properties, e.g. small size and high electrical-to-optical efficiency. For ease of use, most applications require coupling the LD photons to an optical fiber. Attaching the LD-die to a heat-sink is a key packaging procedure. The heat-sink material is generally copper since it is the lowest thermal-resistance metal but its CTE (coefficient of thermal expans ...

There is a critical need for revolutionary approaches for thermal management of 21st century semiconductor devices and hardware, such as advanced high performance computers, high-power laser diodes and solar cells for the conversion of sun light to renewable energy. The one limiting factor for all of the above extremely important and compelling technologies is waste heat management that can remove ...

In our Phase I SBIR MagiQ Technologies demonstrated significant performance advancements in co-site interference cancellation using an optical signal processing approach where we showed ~ 65 dB cancellation of four interferers in the JTRS band. The method exploits the broadband linearity of optical components. In Phase II of this program we propose to further develop the by demonstrating multista ...

Science Research Laboratory proposes to develop a pulsed, tunable mid-IR source with average power greater than 55 watts and high pulse repetition frequency (20 kHz). The program is divided into a baseline and two options. In the baseline program we will develop a continuous-wave laser operating at a wavelength of 2.1 microns with a power of approximately 120 watts. In the option programs, the 2.1 ...

The overall objective of Phase II is the design, production and testing of hybrid composite pressure vessels with embedded optical fiber monitoring to replace steel flasks. The hybrid flasks represent significant weight and acquisition cost savings that will improve ASDS mission capability and readiness. However, the procedures for conducting nondestructive testing to ascertain the strength proper ...

Discovering the important evidence in the form of activities, actors and relationships in a sea of open source data requires the ability to extract and correlate seemingly unrelated pieces of data, distinguish that data from the noise of harmless civilian activity and find the hidden attributes and relationships that characterize the true threat. To meet these requirements, the DAC BOBCAT Team pr ...

SI2 proposes to apply its metamaterial and antenna systems expertise to design and build an efficient miniature wideband metamaterial antenna system that performs close to the theoretical limits of gain and efficiency. The antenna system can be mounted on a number of platforms as the loading effects of mounting are mitigated due to the proposed novel approach. Our approach also includes an intel ...

In this Phase II SBIR program, we will construct a laser source that can be applied to the generation of blue-green laser radiation. Such sources are of great interest to the Navy for both anti-submarine warfare and communications at depth and speed, as blue-green light matches the minimum of seawater transmission for a variety of conditions. In addition, there are military applications in pumpi ...

The need exists for safe, high power density electric lift fans, especially for vertical takeoff and landing (VTOL) air vehicle applications. The unique approach proposed here uses electric power to drive a brushless ring motor and fan inside a duct. The ring motor is scalable and requires no gearing, linkages, or hot-gas plumbing. The low disk loading compared to turbojets and turbofans minimizes ...
