Patent CA-2337285-A1 (CA)
Inventor: ALLAYE-CHAN MARK
IPC: H04J3/08
Filed: 2001-02-15
Abstract: A traffic recovery mechanism for communication networks uses a layer-1 adaptive rate protection scheme that compliments layer-3 restoration mechanisms. The protection scheme allocates less bandwidth to the traffic during a protection switch than during the normal operating conditions. This scheme allows the network to roll off more gracefully from the perspective of the applications routed through it. Rate adaptation is effected by a new interface between the data equipment and the transport network, which switches information transfer rate between two or more predetermined levels.

Title: Automatic speech recognition caller input rate control
Inventor: JOHNSON MARK ALAN
IPC: H04M3/42
Filed: 2001-02-15
Abstract: An apparatus, method and system provide for caller input rate control for automatic speech recognition (ASR) components within interactive communication systems. The various embodiments provide a concentrator functionality to increase the capacity of ASR systems, and provide a delay functionality to continue to provide service to callers during congestion or overload conditions. The delay functionality provides various associated delay modes, including the insertion of silent periods within messages or prompts played to a caller, and providing increased message duration. The preferred method embodiment determines a usage level of a plurality of ASR  input channels, and when the usage level is greater than a first predetermined threshold, provides an associated delay mode for a message output on an output channel of the plurality of output channels. The additional concentrator functionality in the preferred method includes monitoring an energy level of a caller input channel, storing in a memory buffer all received input from that input channel for a preceding period of time, and when the monitored energy level is greater than a predetermined energy level, transmitting the buffered information to an ASR input channel and connecting the caller input channel to the ASR input channel.

Patent CA-2348528-A1 (CA)
Inventor: DURANT PIERRE
IPC: G07F7/10
Filed: 1999-10-29
Abstract: The method is for securely expanding a storage capacity of an IC portable device's memory. For a given data object stored or to be stored in the memory of the IC portable device, a unique master certificate, used as a descriptor of the data object, is generated randomly. The master certificate is indexed in the memory of the portable device. A secondary certificate is derived from and is determinable only using the master certificate. The data object is stored with the secondary certificate on a data storage medium external to the portable device. The memory of the smart card is thus freed from the data object and only the IC portable device has key information to retrieve the data object stored on the data storage medium.
