OEwaves, Inc. proposes to design (Phase I), fabricate, and demonstrate (Phase II) a novel multi-wavelength optical source called a coupled opto-electronic oscillator (COEO) - for UDWDM communications applications. A single COEO simultaneously generates100 more stable optical carriers on a precisely fixed grid that cannot drift (e.g. 25 GHz, 12.5 GHz, 1GHz, or any other desired spacing) and will r ...

THIS PROJECT WILL DEVELOP A SPACECRAFT SUPERCOMPUTER (SSC) FOR FUTURE NASA MISSIONS. THE SSC WOULD HAVE COMPUTATIONAL CAPABILITIES AT LEAST AN ORDER OF MAGNITUDE GREATER THAN CURRENT FLIGHT ARCHITECTURES. BY USING EXISTING OR EMERGING MICROPROCESSOR TECHNOLOGY AND A NOVEL CONNECTIVITY ARCHITECTURE, IT WOULD PROVIDE SUFFICIENT MEMORY AND COMMUNICATION BANDWIDTH RESOURCES FOR MANY SPACECRAFT AND PAY ...

To address efficiency and safety issues associated with the ever-increasing air traffic, NASA and the Federal Aviation Administration (FAA) have engaged in advanced technology development for air traffic management (ATM). The demand for access and use of national airspace is further compounded by the growth of commercial space transportation, which is expected to rise sharply in the 21st century. ...

THIS IS A PROPOSAL FOR AN INEXPENSIVE GIGABIT LOCAL AREA NETWORK (LAN) WHICH AUGMENTS STANDARD LOW SPEED LOCAL AREA NETWORKS SUCH AS ETHERNET OF FDDI FOR GREATLY IMPROVED PERFORMANCE OVER DISTANCES ON THE ORDER OF 1 KM. THE GIGABIT LAN CONSISTS OF SIMPLE INTERFACES RUNNING AT DATA RATES IN THE VICINITY OF 100 MB/S, FIBER-OPTIC LINKS, A CROSSBAR SWITCHING MATRIX, AND A NETWORK CONTROLLER ATTACHED T ...

A PROBLEM OF INTEREST TO THE U.S. NAVY IS THE DEVELOPMENT OF SIGNAL PROCESSING TECHNIQUES TO DETECT AND CLASSIFY THREAT SOURCES OF SHORT-DURATION, ACOUSTIC TRANSIENT EVENTS IN UNDERWATER ACOUSTIC DATA. THE PROBLEM IS VERY DIFFICULT BECAUSE (1) EVERY THREAT SOURCE HAS MANY CLASSES OF ASSOCIATED ACOUSTIC EVENTS, AND (2) THE UNDERWATER ENVIRONMENT HAS AN EVEN GREATER NUMBER OF INTERFERENCE ACOUSTIC E ...

A surveillance system needs to accurately locate and identify not only single targets, but also groups of targets engaged in a common activity. Existing tracking systems are capable of tracking individual targets quite accurately; however, they fail to useinformation related to group behavior in order to improve these estimates. As part of our Phase I work, ORINCON developedAlgorithms those are ab ...

THE SENSITIVITY OF THE THERMOSTRUCTURAL PERFORMANCE OF ROCKET NOZZLES TO CHANGES IN CARBON-CARBON COMPOSITE MATERIAL PROPERTIES HAS BEEN A SIGNIFICANT PROBLEM. RESULTSOF AN AIR FORCE STUDY HAVE CLEARLY INDICATED THAT SIGNIFICANT GAINS IN STRUCTURAL RELIABILITY COULD BE ACHIEVED BY ADOPTING A ROTATED PLY STACKING SEQUENCE WITH WCA-BASED, TWO-DIMENSIONAL CARBON-CARBONS. THIS PROJECT WILL EXAMINE THE ...

The overall objective of this SBIR Phase I research project is to explore the feasibility of very high resolution CMOS APS image sensors intended for use in near ultraviolet imaging for atmospheric and Earth surface studies. Special attention will be paid to specifications dictated by NASA requirements, including pixel count, power consumption, array format, pixel design, and pixel size, with a sp ...

In response to NASA¿s requirement for advanced tele-operating robotic systems, Physical Optics Corporation (POC) proposes to develop a high-fidelity, two-way video communication system that can ensure reliable video communication via progressive transmission and quotient coding modulation. During Phase I, POC will conduct two major efforts: (1) develop a scalable wavelet coder to compress the v ...

Physical Optics Corporation (POC) proposes to develop a compact, low cost, widely tunable (visible to IR), rugged, high-optical-density tunable bandwidth filter system (TBFS) for hyperspectral airborne and ground-based sensing. This filter system is based on the unique integration of a pair of thin Raman holographic edge filters within a rotating lens. In this compact configuration, the TBFS can b ...
