Title: Adaptive current controller for a fuel-cell system
Inventor: MASSE STEPHANE
IPC: H01M8/04
Filed: 2005-07-12
Abstract: Fuel cell modules usually have an inherently limited load slew rate, which is adequate for some applications but insufficient where close load following is desired. An example of where the inherent lack of dynamic response, of a typical fuel cell module, has proven to be insufficient is within a standalone AC power generation system in which the fuel cell module does not, or cannot, possibly, receive a priori knowledge of current demand changes by load. In contrast, the present invention aims to provide a current controller for use in a fuel cell system, a fuel cell system with adaptive current control and a method of operating a fuel cell system that employs an adaptive current controller that enables a relatively fast dynamic response to abrupt increases in current demand whilst also providing a controlled adjustment to the output current provided by a fuel cell module included in the system. The adaptive current control system includes a fuel cell module, an ultra-capacitor, a current limiter, and a processor with several inputs and at least one output for detecting and controlling current conditions in the fuel cell system.

Title: Targeted and high density drug loaded polymeric materials
Inventor: SALTZMAN WILLIAM MARK
IPC: A61K9/14
Filed: 2005-06-30
Abstract: Polymeric delivery devices have been developed which combine high loading/high density of molecules to be delivered with the option of targeting. As used herein, ~high density~ refers to microparticles having a high density of ligands or coupling agents, which is in the range of 1000-10,000,000, more peferably between 10,000 and 1,000,000 ligands per square micron of microparticle surface area. A general method for incorporating molecules into the surface of biocompatible polymers using materials with an HLB of less than 10, more preferably less than 5, such as fatty acids, has been developed.  Because of its ease, generality and flexibility, this method has widespread utility in modifying the surface of polymeric materials for applications in drug delivery and tissue engineering, as well other fields. Targeted polymeric microparticles have also been developed which encapsulate therapeutic compounds such as drugs, cellular materials or components, and antigens, and have targeting ligands directly bound to the microparticle surface. Preferred applications include use in tissue engineering matrices, wound dressings, bone repair or regeneration materials, and other applications where the microparticles are retained at the site of application or implantation.  Another preferred application is in the use of microparticles to deliver anti-proliferation agents to the lining of blood vessels following angioplasty, transplantation or bypass surgery to prevent or decrease restenosis, and in cancer therapy. In still another application, the microparticles are used to treat or prevent macular degeneration when administered to the eye, where agents such as complement inhibitors are administered.

IPC: G09G3/34
Filed: 2005-08-09
Abstract: A two-dimensional image projection device using array of micromirror array lenses and a random scanning technique is invented. Using the random scanning technique, the light efficiency is nearly doubled than that of the prior art.  The invention makes a brighter and less power consuming display device possible. Because each micromirror array lens of array of micromirror array lenses can scan whole image plane, a fast self diagnosis and correction technique can be introduced in displaying device. The Self diagnosis and correction technique makes display device to maintain image quality even a few tens percent of micromirrors do not work properly. Owing to the scanning characteristics of micromirror array lens, the image projection device can express the same number of pixels image with less number of micromirrors than the prior art. This also enables small sized two-dimensional image projector, which can be incorporated in portable electronic equipments.
