Title: Demodulation apparatus and method in a communication system employing 8-ary psk modulation
Inventor: KIM MIN-GOO
IPC: H04L25/06
Filed: 2002-08-13
Abstract: An 8-Ary PSK demodulation apparatus for receiving an input signal Rk(Xk, YK) comprised of a kth quadrature-phase component Yk and a kth in-phase component Xk, and for generating soft decision values .LAMBDA.(SK,0), .LAMBDA.(SK,1), and .LAMBDA.(SK,2). A calculator calculates Zk by subtracting a level |Y| of the quadrature-phase signal component YK from a level |XK| of the in-phase signal component Xk. A first selector selects the Zk, according to an MSB of the quadrature-phase signal component Yk. A second selector selects the Zk or the reverse ZK according to an MSB of the in-phase signal component Xk. A  third selector selects an output of the second selector or a value "0"  according to an MSB of the ZK.

Patent CA-2427266-A1 (CA)
Inventor: BAYLES LEN ALBERT
IPC: G06F17/30
Filed: 2001-11-01
Abstract: A preferred embodiment of the present invention integrates a domain name monitoring and acquisition service (116, 118) with a registry system (110, 112). The monitoring and acquisition service can receive a request from a registrar (100) to acquire a domain name. The monitoring and acquisition service also can receive a pending delete notification from the registry for a domain name having a registration that is about to be deleted. The pending delete notification can be received before the registry issues a public delete notification or purges the domain name, at which point the domain name is registrable by the first-responding registrar. If the domain name that is the subject of the pending delete notification has a corresponding acquisition request received by the monitoring and acquisition service, the monitoring and acquisition service can request acquisition of the domain name for the requesting registrar.

IPC: H04M3/42
Filed: 2003-09-29
Abstract: A method and apparatus are set forth for defining and validating featur e policies in an execution system, such as a communication system. The method includes entering user policies described ire a straightforward manner (e.g. using a Web browser and user-understandable language) in such a way that they can be translated into a formal executable language. The user policies are then translated int o an executable feature language such as the IETF's CPL. The user is then either compelled or provided with an option to validate the overall feature set before it is uploaded to the execution system. If validation is selected, the features are translated from CPL into another format, such as FIAT, from which it is possible to detect commo n feature specification errors. The FIAT detected errors are then analyzed in a manner that is aware of the expectations and common errors of naive users, and interpreted to determine possible errors as errors that are common to nave users. These eurors are reported to the user (e.g. via the Web interface) in terms that are understandable to naïve users and compatible with how the policies were originally described. The user is provided with options to either accept the interactions as they are, repa ir them manually or to accept a recommendation of an automatiic correction. Unlike conventional systems, where feature interactions are solved in the same way for all users, the selected resolution is personalized in the present invention to satisfy the end-user's intentions, independently of how others solve similar conflicts. The features are uploaded to the execution system.

Title: Network channel access protocol - interference and load adaptive
Inventor: HAMMEL THOMAS
IPC: H04L12/56
Filed: 2002-04-15
Abstract: Network channel access protocol is disclosed. More particularly, a distributed, locally determined, channel access protocol that adapts to load, avoids interference and controls access by a group of nodes to a set of shared channels is disclosed. Shared channel space is divided into a number of communication slots that are repeated at a predetermined interval. Permission to use a slot to communicate between any two nodes is dynamically adjusted by the channel access protocol, which locally: (i) estimates load to neighboring nodes; (ii) allocates or deallocates slot usage to adapt to load and avoid interference; and (iii) asserts and advertises slot usage within an interference area about itself.
