Title: Improved radiation synthesizer systems and methods
Inventor: MERENDA JOSEPH T
IPC: H04B1/20
Filed: 2001-01-24
Granted: 2010-05-04
Abstract: Synthesizer radiating systems provide efficient wideband operation with an antenna, such as a loop, which is small relative to operating wavelength. Energy dissipation is substantially reduced by cycling energy back and forth between a high-Q radiator and a storage capacitor. Wideband operation is achieved by actively controlling power switch devices. Dissipation is further reduced during high speed switching by use of sequential switching methods to avoid dissipation of energy capacitively stored in switch capacitances, including switch control circuit capacitance. Systems using multi-segment loop antennas are arranged to match antenna input impedance to switching circuit parameters. Personal transmit/receive systems mounted on a jacket or other clothing for field use are enabled.

Abstract: On a découvert avec surprise suite à une recherche intensive qu'il est possible de préparer une 2-halo-4,6-bisaryl-1,3,5-triazine avec une sélectivité et une efficacité sans précédent, dans des conditions douces et avec un rendement élevé par réaction d'halogénure cyanurique avec des composés aromatiques en présence d'au moins un acide de Lewis et d'au moins un promoteur de réaction. Cette réaction est également sans précédent du fait que divers composés aromatiques peuvent être utilisés pour produire une vaste sélection de 2-halo-4,6-bisaryl-1,3,5-triazines. Cette nouvelle approche consiste à utiliser les promoteurs de réaction en combinaison avec au moins un acide de Lewis dans certaines conditions de réaction pour promouvoir la formation de composés de 2-halo-4,6-bisaryl-1,3,5-triazines à partir d'halogénure cyanurique. De préférence, les acides de Lewis et les promoteurs de réaction sont combinés pour former un complexe. Ces 2-halo-4,6-bisaryl-1,3,5-triazines sont des intermédiaires clés pour préparer une classe d'absorbeurs d'UV base de 2-(2-oxyaryl)-4,6-bisaryl-1,3,5-triazine.

Abstract: The soft state of a header compression scheme in a communication system carrying packet traffic including a real time communication signal can be updated (63) during periods of communication signal inactivity (62), during which there is no need to transmit the communication signal. The header compression soft state can also be updated by stealing bits (83, 84) from the communication signal to carry the header update information (73). If the communication signal includes source encoded data, the header compression soft state can be updated selectively (126) based on the bit rate (122, 124) of a codec that produced the source encoded data.
