Title: Network architecture for routing of adjunct based services
Inventor: RICCIARDI DOMINIC
IPC: H04Q3/00
Filed: 1996-12-16
Granted: 2001-04-03
Abstract: The present invention is a novel architecture design for adjunct based architectures. The architecture is built on two key principles; routing traffic based on geographic origin and routing based on customer group. In order to implement the geographic routing, the communications network is split into regions. A method used to achieve optimal regions is described. Further realization of the geographic routing entails a design of the architecture regions, determining the number of adjuncts/region and equally distributing the loads across the adjunct sites. Also, described is the method for optimally homing traffic between the OAS and TAS A and between TAS A and TAS B. The architecture eliminates deficiencies in prior art architectures such as intertoll focusing, architecture instability and reliability.

Title: Microwave method to detect and locate cancers in heterogenous tissues
Inventor: BRIDGES JACK E
IPC: A61B5/05
Filed: 1997-04-28
Granted: 2004-11-23
Abstract: A method and system for detecting an incipient tumor in living tissue such as that of a human breast in accordance with differences in relative dielectric characteristics. A generator produces a non-ionizing electromagnetic input wave of preselected frequency, usually exceeding three gigahertz, and that input wave is used to irradiate the living tissue, being effectively focused into a minute, discrete volume within the tissue to develop a non-ionizing electromagnetic wave at that position. The illumination location is shifted over a portion of the living tissue in a predetermined scanning pattern. Backscatter signal returns from the living tissue are collected to develop a backscatter return signal wave. The backscatter wave is processed to segregate skin tissue backscatter to develop a segregated backscatter wave signal; that segregated signal, in turn, is employed to detect any anomaly, caused by differences in relative dielectric characteristics, that is indicative of the presence of a tumor or other abnormality in the scanned living tissue.

Plural sample containers for holding samples are arrayed on the sample turntable.          Plural reaction containers are arrayed on the reaction turntable.          A sampling pipette draws in a sample from some sampling container and injects the sample into some reaction container. A reagent pipette draws in some reagent from some reagent container and injects the reagent into the same reaction container. The resulting mixture is stirred by a stirring device. Produced reaction products are detected by a detector. Let N be the number of the reaction containers on the reaction turntable. The reaction turntable is rotated in M pitches in one step. Note that M and N do not have any common factor. First and second injecting positions adjacent to each other are established as positions where the reagent pipette can inject a reagent into the reaction container in position. First and second stirring positions adjacent to each other are established as positions where the stirring device can stir liquids in the reaction container in position. The stirring device can be moved between the first and second stirring positions.          Thus, one reagent pipette can be used for two kinds of reagents.          Also, one stirring device can be used for two kinds of reagents.

Title: Method and apparatus for mitigating the effects of interference in a wireless communication system
Inventor: ROZANSKI WALTER JOSEPH JR
IPC: H04B15/00
Filed: 1997-03-10
Granted: 2001-10-09
Abstract: A wireless communication system (200) estimates (303) the location of a mobile station (215) when a degradation in the mobile station's communication occurs due to interference, and stores (305) the location estimate in a database. The database is used to determine the potential for the mobile station (215) within the wireless communication system to receive interference based on its estimated location or its proximity to the known interference location. When the mobile station (215) is within a predetermined distance of the known interference location, the likelihood for the mobile station (215) to experience a degradation in call quality, duration, etc. increases. To migitate the degradation due to interference, an alternate carrier (104) is found and if available, the mobile station's communication is handed off to the alternate carrier (104). Attenuation can also be added in the front-end of the mobile station (215) to mitigate the degradation due to interference.

Title: Optical disc copy management system
Inventor: BLAUKOVITSCH REINHARD
IPC: G09C1/00
Filed: 1998-08-06
Granted: 2007-01-23
Abstract: The invention relates to a method of obtaining a copy protected optical record carrier carrying information in different blocks, a method of accessing such a copy protected optical record carrier and such an optical record carrier itself. Access means for optical record carriers return different results when retrieving blocks, which contain incorrect address data in the corresponding subcode fields. A copy protection key will be implemented during manufacture of an optical record carrier by modifying the subcode address information of a predetermined pattern of blocks. It is normally not possible to copy incorrect address data onto an optical record carrier, since the address data will be newly generated during the copy process. Therefore, such a key can be utilized to distinguish between an original disc and a copied or non original disc. The key is preset before manufacturing of the optical record carrier itself and can therefore be used to encrypt the data stored on the optical record carrier. Upon accessing of the data, first the key is extracted from the optical record carrier and then the data can be decrypted utilizing this key.

Title: Method and system for a unicast endpoint client to access a multicast internet protocol (ip) session
Inventor: ZELEZNIAK ALEKSANDR
IPC: H04M3/56
Filed: 1998-08-26
Granted: 2003-04-22
Abstract: Unicast endpoint clients (110, 111, 115) on an IP Unicast network (107, 108) are provided access to Multicast sessions on an IP Multicast network (101) through a Multicast-Unicast gateway server (120, 121). The server obtains information about sessions on the Multicast network and makes such information available to a Unicast client on the Unicast network upon request bythe client. Upon being presented with a list describing the subject matter of each session, the user at the Unicast client selects the session to which he or she wants to join, which causes the Multicast-Unicast server to join the appropriate session on behalf of the requesting client for each media type in which the joining client wants to be a participant. The server then sets a bi-directional Unicast User Datagram Protocol (UDP) stream between itself and the client. All packets then received by the server from the Unicast client are address-translated to the appropriate Multicast session address. In addition, all packets received by the server on the Multicast session address are address-translated and sent to the Unicast client. The Unicast client is then able to participate in the Multicast session as both a sender and a receiver of packets to and from other Unicast and Multicast clients which are active during the session. Further, the Unicast client is capable of creating a new session, recording a session in the network for later retrieval and playback, and creating and accessing low bandwidth versions of existing sessions.
