Patent CA-2341219-A1 (CA)
Title: Method and apparatus for determining whether a verbal message was spoken during a transaction at a point-of-sale terminal
Inventor: TEDESCO DANIEL E
IPC: G06Q20/20
Filed: 1999-08-12
Abstract: A point-of-sale terminal initiates a transaction and provides a prompt to be spoken to an operator (e.g. a cashier) of the POS terminal. The prompt indicates a verbal message that is to be spoken by the operator. The POS  terminal then receives an audio signal via a microphone or similar device to record what the operator has spoken. Using speech recognition, the POS  terminal determines whether the audio signal corresponds to the prompt, and thus whether the operator spoke the prompt properly. In one embodiment, the transaction is paused until the operator properly speaks the prompt. In another embodiment, the POS terminal stores an indication of whether the operator has properly spoken the prompt, thereby allowing the performance of the operator to be measured.

Title: Adaptive data scheduling using neighboring base station load information for tdma systems
Inventor: RUDRAPATNA ASHOK N
IPC: H04L12/56
Filed: 2001-06-29
Abstract: A telecommunications system having a first base station that utilizes neighboring base station load information to adaptively schedule transmissions to mobile devices within the first base station's coverage area. Before transmitting information to a mobile device, the first base station determines whether neighboring base stations causing the most interference to the mobile device have a load below a loading threshold (i.e., if the neighboring base stations are "lightly loaded"). If the first base station determines that the neighboring base stations are lightly loaded, then the neighboring base stations are providing little to no interference to the mobile device at which point, the first base station should transmit to the mobile device with high priority. If the first base station determines that the neighboring base stations are not lightly loaded, then the neighboring base stations are providing sufficient interference to the mobile device that transmissions to the mobile device should be given low priority. Thus, the first base station schedules transmissions at times when the transmissions can be made at high data rates, which increases the data rates of the mobile devices and the overall throughput of the system.

Title: Fifo-based network interface supporting out-of-order processing
Inventor: YANG LI-JAU
IPC: H04L29/06
Filed: 2000-11-30
Abstract: Support for priority and IP security packets, and other protocols at the network interface level and in conjunction with FIFO-based packet buffers is provided by allowing out of order processing of certain packets in the FIFO. The optimized character of FIFO for sequential transfer is maintained, while particular types of packets are processed out of order to achieve minimum latency and maximum data security in an intelligent network interface card (10). A buffer (15) stores data packets in an order of receipt. Logic is included in the network interface to transfer packets out of the buffer (15) according to the order of receipt, and according to the respective packet types so that packets having a particular packet type are transferred out of the order of receipt relative to packets having other packet types.

Title: Key management between a cable telephony adapter and associated signaling controller
Inventor: MEDVINSKY SASHA
IPC: G06F1/00
Filed: 2000-04-07
Abstract: A highly scalable key management architecture for secure client-server syste ms used in IP telephony network, wherein cryptographic state needs to be saved only by the clients. This architecture takes advantage of existing key management protocols, Kerberos with the PKINIT (public key) extension, to provide an IP telephony system having a high degree of scalability. In the case of lost security associations, the architecture provides for lightweigh t rekeying operations that allow clients to quickly re-establish the lost association or switch to a different server. The key management architecture  includes a method for establishing a secure channel between an IP telephony endpoint and Server in an IP telephony network. The endpoint is coupled to a  user and the Server is coupled to the IP telephony network. The method comprises steps of transmitting from the endpoint to a key distribution cent er a request for a security ticket, receiving the security ticket from the key distribution center, transmitting from the endpoint to the Server a request for a sub-key, receiving the sub-key from the Server, and establishing a secure channel between the endpoint and the Server using the sub-key.</SDOAB >

Title: Tightly-coupled disk-to-cpu storage server
Inventor: TAYLOR CLEMENT G
IPC: H04N21/218
Filed: 2000-03-30
Abstract: A storage server (110) for efficiently retrieving data from a plurality of disks (212) in response to user access requests. The server comprises a plurality of processors (302) coupled to disjoint subsets of disks, and a custom non-blocking packet switch (220) for routing data from the processors to users. By tightly coupling the processors to disks and employing an application-specific switch, congestion and disk scheduling bottlenecks are minimized. By making efficient use of bandwidth, the architecture is also capable of receiving real-time data streams from a remote source and distributing these data streams to requesting users. The architecture is particularly well suited to video-on-demand systems in which a video server stores a library of movies and users submit requests to view particular movies.

Inventor: SOININEN JONNE
IPC: H04L12/56
Filed: 2000-06-06
Abstract: In an access network which supports macro mobility management, an access node (SGSN) checks (3) during an attach procedure of a mobile station (MS) whether the mobile has macro mobility capability, i.e. whether there is a potential need for macro mobility services. Macro mobility entity (FA2) may be any entity which provides a point of attachment on the macro mobility level, such as a mobility agent in Mobile IP type mobility management. If there is no mobility capability, a normal attach procedure is performed. However, if there is macro mobility capability, the access node (SGSN) selects a suitable mobility entity (FA2) to the mobile station (MS), sends the identity of the selected mobility entity to the mobile station and requests (8) the mobile station to initiate an activation of a packet protocol (PDP) context in the system.
