DESCRIPTION (provided by applicant): The ultimate objective of this proposed program is the commercialization of a universal transcutaneous energy transfer (TET) system with a high performance implantable battery. This integrated power system will be adapt able to a host of next generation fully implantable mechanical circulatory support (MCS) systems. To date, fully implantable systems (i.e. the ...

DESCRIPTION (provided by applicant): The goal of this proposal is to produce a fully characterized polyurethane heart valve prosthesis that will be ready for clinical evaluation. Existing replacement valves suffer from several shortcomings. Specifically, biological tissue fixation and methods used to mount the tissue to the supporting stent of bioprostheses cause time dependent structural changes ...

DESCRIPTION (provided by applicant): Ischemic ventricular tachycardia (VT) is a contributing cause to more than half of the 300,000 sudden cardiac deaths that occur annually in the United States. Implantable cardioverter defibrillators (ICDs) are the stand ard therapy but they are expensive the total cost of an ICD implant approaches 50,000 and the United States spends more than 2.2B on these im ...

Realizing the promise of nuclear fusion depends in part on effective plasma facing components (PFCs) that can withstand the intense heat loads, forces, and neutron bombardment of long-pulse high-power reactor operation. A single reactor such as ITER will require thousands of PFCs. Because imperfections in the joints of just one PFC could have disastrous consequences for reactor operation, joint ...

Many military missions involve the use of equipment that requires small batteries for power where AC grid power is unavailable. Also, there is a need for a high quality power output device that conditions a power input to make it suitable to power sensitive communications equipment. The weight of this equipment is also a factor which affects Its usefullness in quick moving military situations. M ...

Solid oxide fuel cells (SOFCs) are one of the most efficient and cleanest power generating systems being developed. A key component is the cathode air heat exchanger, or recuperator, which ensures that the cathode air, and thereby the cells, are at sufficient temperature to permit ion mobility ¿ and thereby improve overall SOFC system efficiency. At present, commercially available metallic recu ...

The proposal would provide the design and basic product development work to augment the power generation efficiency of fuel cells developed by Acumentrics Corp. by converting waste heat into electricity by highly efficient thermoelectric (TE) power generation. Three paths will be explored in Phase I to add a TE generator to the SOFC. The first will explore the use of a material that is used in co ...

A conceptual design of a battery charging station with UPS back-up capability was completed under contract M67854-C-6509. The resulting system can charge up to twelve BB-2590 batteries at the maximum charging current (to minimize charging time) and provide 1000 Watts of back-up power (both AC and DC outputs are provided) for at least one hour. Individual batteries can be hot-swapped for field us ...

R3Logic, Inc., in collaboration with Tezzaron Semiconductor will develop a rad-hard multi-core embedded processor / memory system that will be fabricated in a multi-layer 3-D integrated circuit. Phase I will focus on the system design. We will complete the RTL to GDSII synthesis of the processor and system components. The stack will incorporate Tezzaron’s patented 3-D Octopus memory, which has b ...
