The SBIR.gov award data files now contain the required fields to calculate award timeliness for individual awards or for an agency or branch. Additional information on calculating award timeliness is available on the Data Resource Page.
SBC: SCIENTIFIC SYSTEMS CO INC Topic: N11AT012
The predominant method used in electronic support measure (ESM) systems to detect and geolocate noncooperative RF emitters employs arrays of antennas to estimate signal angle of arrival (AOA). There are several issues that preclude wide installation and use of these for emitter geolocation. One issue is accuracy. There are various error sources, including signal noise, multipath effects, and ambig ...STTR Phase II 2013 Department of DefenseNavy
SBC: VESCENT PHOTONICS LLC Topic: N13AT018
Vescent Photonics proposes to develop a compact laser system and integrate it with a cold-atom micro primary standard developed under the DARPA IMPACT program. In phase I we will investigate performance enhancements resulting from immobilizing the cold-atom sample with an optical lattice formed from an optical field whose wavelength is chosen to minimize the differential light shifts between the s ...STTR Phase I 2013 Department of DefenseNavy
SBC: APTIMA INC Topic: N13AT020
The Navy"s mission success increasingly relies on complex decision support systems and automation. Navy command and control systems must provide the users with the right information, at the right time, depending on the context in which they are operating, and must do it in a proactive manner. Today, massive quantities of data are passed blindly between nodes, with no ability to adapt the delivery ...STTR Phase I 2013 Department of DefenseNavy
SBC: VIVONICS INC Topic: N13AT021
Continuous physiological monitoring can provide invaluable insight into the status of the person monitored. The right sensors can provide important information related to both the physical and mental state of the subject. Although sensing modalities and the information that can be gleaned from them is a fairly well advanced science, the sensors themselves lag behind in terms of being sufficiently ...STTR Phase I 2013 Department of DefenseNavy
SBC: SPECTRAL SCIENCES INC Topic: N13AT011
Composite materials are widely used in aircraft to reduce weight and cost, improve structural performance, and boost fuel efficiency. However, composites are susceptible to adhesive bond quality issues, including kissing bonds which may occur because of initial fabrication or service related issues. Detection of such weakened bonds requires an easily used detection approach to routinely monitor co ...STTR Phase I 2013 Department of DefenseNavy
SBC: IMAGE ACOUSTICS, INC. Topic: N11AT026
This STTR Phase II Proposal addresses the need for a low cost acoustic transmitter that combines a power amplifier, control-circuitry and an innovative transducer assembly, all at a low cost. Our approach is to use a cylindrical modal vector projector transducer which becomes part of the housing and, moreover, uses only a minimum of power to provide a sizable source level. The modal vector project ...STTR Phase II 2013 Department of DefenseNavy
SBC: CHARLES RIVER ANALYTICS, INC. Topic: N11AT031
Submarine commanders must make complex decisions to accomplish increasingly diverse missions. Moreover, concurrent missions may involve contradictory requirements. Planning must also account for the unexpected, including equipment failures, environmental factors, or external events that impact the ship's mission(s). Since all submarine operations involve a degree of risk, the commander must b ...STTR Phase II 2013 Department of DefenseNavy
SBC: METIS DESIGN CORP Topic: N12AT007
This STTR aims to develop a novel method for detecting and tracking growth of cracks in rotorcraft gearbox. Aerospace structures are subject to dynamic loading. In particular, gearbox components experience continuous cyclic loading, wear and eventually develop fatigue cracks. As opposed to most other aircraft components, gearbox components are non-redundant, so a failure can have catastrophic cons ...STTR Phase II 2013 Department of DefenseNavy
SBC: ROBOTIC RESEARCH OPCO LLC Topic: N13AT016
Autonomous systems continue to be outfitted with larger amounts of sensors that are capable of collecting extremely large amounts of data over the course of a mission. Even autonomous systems with high storage capacities can run into storage limitations when burdened with large amounts of sensor data over long mission durations. This proposal will develop a Learning-based Approach for Relevant Dat ...STTR Phase I 2013 Department of DefenseNavy
Gallium Nitride (GaN)-based High Efficiency Switch/Transistor for L-Band RF Power Amplifier ApplicationsSBC: MIMOCLOUD INC Topic: N13AT025
This research seeks to develop a method of developing solid-state power amplifiers that operate at 300 Volts, achieve 100 Watt output and greater than 90% efficiency at 1 GHz with 10% bandwidths. We will seek to demonstrate switch-mode amplifiers that use a novel gate design with Gallium Nitride forming the basis for solid state power amplification.STTR Phase I 2013 Department of DefenseNavy
