US Navy submarine forces currently employ an independent team to test, measure, calibrate and certify radio frequency (RF) signal paths through sail mounted antennae to the inboard radio rooms in a process that can take in excess of 60 man-days to complete. Ships personnel have no means of calibrating or performing an operational verification of the ES suite once underway. Ships have no means of p ...

Detectors and radiation monitors for future high energy and nuclear physics experiments must be able to withstand radiation environments several orders of magnitude harsher than those of any current device. At present, most radiation detectors are based on silicon technology, however, the practical radiation hardness limit of silicon falls far short of requirements in future high ener ...

Ethylene and propylene are the primary feedstocks for the manufacture of polyethylene and polypropylene, respectively. These olefins represent a major component of the polymer manufacturing cost. Consequently, there is significant economic benefit in minimizing losses of unreacted olefin from the process. Some olefin loss is a result of the need to remove paraffin from the polymerization reactor ...

Synchrotron-based science has had a great scientific impact and will continue to have great impact going forward. In spite of the large investment in the 3rd generation light sources, most beam lines do not preserve the sources phase profile or brightness all the way to the sample. For these high brightness light sources, errors are almost completely due to distortion in the front-end optics cau ...

Current energy storage devices have energy densities that are barely sufficient for low cost electric-vehicles and rely on lithium ion batteries that use flammable, unsafe, liquid electrolytes. However, in order to replace liquid electrolyes in lithium batteries for hybrid electric power train systems, solid polymer electrolytes, which have the advantages of safety and flexibility, must attain con ...

Yardney Technical Products in conjunction with Johns Hopkins University Applied Physics Laboratory is proposing to progress development of an advanced monitoring system for batteries, provide a modular battery unit, and develop a system approach to monitor and control multiple power sources and loads. Battery monitoring will be advanced via a technique to determine the internal temperature of each ...

Yardney Technical Products, Inc., with SBIR partners, Brown University and Fraunhofer LLC, propose to develop a high energy density, high power, bipolar battery. Bipolar battery designs are inherently the most volumetrically efficient batteries. Further, the elimination of the external intercell connections greatly improves the rate capability and solves the issue of making a very low capacity, hi ...

DBV Technology, LLC proposes to design, build, integrate and test an array of undersea acoustic instruments capable of scoring multiple projectiles impacting the ocean surface closely spaced in both position and time using algorithms developed during Phase I. A 48 month period of performance is proposed consisting of one 12 month base period, with three subsequent 12 month options. Instrument oper ...

Naval aircrafts are covered with many antennas for VHF/UHF Line-of-sight communications, UHF SATCOM, L-band, and GPS functions. The blade type antennas employed have limited bandwidths. Low-profile cavity-backed antennas will require hull penetration inside the aircraft. Thus, the objective of this program is to investigate innovative concepts such as the Dielectric Resonator Antenna (DRA) to achi ...

This effort to improve the capabilities of the ESM system will increase the reliability and reduce lifecycle support costs of the Radar Wideband (RWB) subsystem on submarines. Analog to digital converter (A/D) based digital receivers will be applied to yield improvements in Radar signal acquisition and processing. In-phase and Quadrature (I/Q) data streams will be created from which intra pulse mo ...
