ABSTRACT: Data compression schemes generally fall into two main categories: lossless and lossy. Lossless schemes promise to provide an uncompressed file which is identical before and after compression. As lossless schemes must be able to reconstruct every feature of the original file they often provide modest compression ratios. In fact, it is easy to show that no lossless compression scheme ...

ABSTRACT: By reducing radiation through rad-hard design, device modeling and manufacture process, we at MIAO LLC technology will provide a state of art solution for 130 nm CMOS/SOI space borne, 10 MHz bandwidth with over 114 dB signal-to noise ratio (SNR) delta-sigma analog-to-digital converters at Total Ionizing Dose greater than 1 MRads. The device power consuming is estimating less than 80 mW ...

ABSTRACT: The K-128 co-processor leverages insights from neuroscience to achieve superior performance. Unlike previous efforts along those lines, our approach is to create a software programmable co-processor that runs existing applications. One of the most salient characteristics of such a co-processor is its power efficiency: not just a few percent more efficient than a traditional processor, b ...

Missile modernization and future missile designs are utilizing more sophisticated and higher powered electronics in the pursuit of extended missile range, improved accuracy and precision targeting for striking enemy threats. Tight packaging and sophistication of these electronic systems can generate significant heat loads, which needs to be dissipated efficiently in order to maintain functionality ...

ABSTRACT: This Phase I effort will involve the development of an ultra low cost, high specific power, modular and flexible solar array module using currently available thin-film solar cells, innovative interconnects, and flexible encapsulation. The high efficiency thin-film solar cells will enable high specific power and flexibility in the module. The interconnect scheme and encapsulation will a ...

ABSTRACT: Numerica is proposing to extend its mature multiple hypothesis tracking (MHT) technology by providing additional estimation and data fusion algorithms to support improved space object detection, tracking, identification, and characterization. An extended program would aim to develop a feature-aided MHT (FA-MHT) capability that (i) exploits both kinematic and feature data including light ...

ABSTRACT: The proposed effort will perform a feasibility study on developing a multispectral scene projector from 0.4µm to 5µm, using liquid crystal on Silicon (LCoS) spatial light modulators (SLMs). BNS has successfully developed scene projector technology using this approach previously. A modular approach will be considered in which additional spectral band scene projector arms (SPAs) can be ...

ABSTRACT: An ability to reduce the weight of cables has the potential to provide significant cost savings, reduce maintenance and improve reliability of satellites. The costs of developing and producing satellites are linearly proportional with the satellite"s weight, with each kilogram costing around $1 million when delivery-to-space costs are included. With global satellite launches expected to ...

ABSTRACT: A key problem in the rapid and lower cost development of spacecraft is that the various devices that comprise the spacecraft bus do not typically provide a single standard interface and/or communications protocols. This forces a design-to-order paradigm in which a spacecraft bus is developed on a per-mission basis with little reuse of existing software. Efforts such as SOA have defined ...

ABSTRACT: Hypersonic propulsion systems, such as supersonic combustion ramjets (scramjets) are generally expected to operate from Mach 3.5 up to Mach 7-8 and are designed for specific flight Mach numbers to achieve optimum performance. However, realistic flight vehicles will experience a wide range of flight conditions during a typical mission. These off-design flight conditions degrade the perfo ...
