Inventor: MCCALLISTER RONALD D
IPC: H04L7/00
Filed: 1996-09-17
Abstract: Récepteur (10) de communications numériques qui prend un échantillon complexe (20) d'un signal (12) analogique de bande de base par symbole. Un convertisseur (26) rectangulaire-polaire sépare les attributs de phase des échantillons complexes des attributs d'amplitude. Un processeur (28) de phase identifie les opportunités d'ajustement d'horloge qui surviennent lorsque des changements de phase relativement grands ont lieu entre des symboles consécutifs. Un processeur (32) d'amplitude influence la durée de symbole uniquement pendant les opportunités d'ajustement d'horloge. Ledit processeur (32) d'amplitude avance la synchronisation de symbole dans une boucle à phase asservie lorsque des changements d'amplitude décroissants sont détectés pendant des opportunités d'ajustement d'horloge et retarde la synchronisation de symbole lorsque des changements d'amplitude croissants sont détectés pendant des opportunités d'ajustement d'horloge. Un interpolateur (66) peut être utilisé pour estimer des valeurs d'amplitude entre des échantillons si bien que le changement d'amplitude est déterminé entre des valeurs d'amplitude échantillonnées et des valeurs d'amplitude estimées.

IPC: A61K49/22
Filed: 1998-06-30
Abstract: It has been discovered that microparticles formed from natural or synthetic polymer with thicker walls have significantly enhanced echogenicity as compared with microparticles having thinner walls.

In the preferred embodiment, the polymers are synthetic biodegradable polymers and the wall thickness is between about 100 and 660 nm, although wall thicknesses from about 20 nm to in excess to 500 nm can be used. The microparticles are manufactured with a diameter suitable for the targeted tissue to be imaged, for example, with a diameter for between 0.5 and 8 microns for intravascular administration, and a diameter of between 0.5 and 5 mm for oral administration for imaging of the gastrointestinal tract or other lumens.  Preferred polymers are polyhydroxy acids such as polylactic acid-co-glycolic acid, polylactide or polyglycolide, most preferably conjugated to polyethylene glycol or other materials inhibiting uptake by the reticuloendothelial system (RES). The microspheres may be used in a variety of ultrasound imaging applications including cardiology applications, blood perfusion applications as well as for organ and peripheral vein imaging.
