Abstract: A generator transfer switching system having a multi-position generator transfer switch that enables a homeowner or user to manually select a group of circuits from among a number of pre-selected groups of circuits for transfer from utility company service to a standby generator via a single cam-operated switch. The multi-position generator transfer switch is comprised of a contact block having multiple stages with a shaft and a handle to turn the shaft. Each stage contains electrical contacts and cams operably connected to the contacts. The cams are mounted on a shaft running through the center of the block and connected at one end to a handle. The handle can be manually turned to switch a group of selected household circuits from the utility company service to an electric generator service. The switch eliminates the potential for electrical back feed from either the utility company to the generator or from the generator to the utility company.

Title: Programmable optical multiplexer/demultiplexer
Inventor: MAROM DAN MARK
IPC: H04B10/27
Filed: 2002-04-29
Granted: 2005-09-20
Abstract: A programmable optical demultiplexer can independently assign every input optical channel in a WDM optical communications signal to depart from any desired output port. The demultiplexer device can also be operated in the reverse direction, and thus achieve programmable optical multiplexer functionality, by accepting different wavelengths at each of multiple input ports and efficiently combining the wavelength channels at the multiplexer output port. The programmable multiplexer/demultiplexer device has an optical arrangement for spatially dispersing the optical wavelengths, and tunable micro-mirrors for beam steering each channel independently. Controlling the beam reflection direction determines the connectivity between the input and output ports at the wavelength level.

Abstract: La protéine tensioactive D (SP-D) est un élément à 43-kDa de la famille des collectines composée des protéines du collagène contenant un domaine de lectine, qui est exprimé dans les cellules épithéliales du poumon. Le gène SP-D a été ciblé par recombinaison homologue dans des cellules souches embryonnaires qui ont été utilisées pour produire des souris SP-D (-/-). La carence SP-D (-/-) a provoqué une inflammation, une production accrue d'oxydants par des macrophages alvéolaires isolés, une structure et des niveaux de tensioactifs anormaux et une expression de SP-A réduite. L'invention se rapporte par conséquent à la souris SP-D(-/-) en tant qu'excellent modèle pour l'emphysème. L'invention se rapporte également à des modèles permettant de tester des traitements de l'emphysème dans le modèle murin, à des procédés d'utilisation de la protéine ou de l'ADN SP-D pour le traitement et le diagnostic de l'emphysème et des infections pulmonaires.
