Inventor: HSU DE D
IPC: G06F7/00
Filed: 2001-02-23
Abstract: Selon l'invention, deux multiplicateurs-accumulateurs sont couplés de sorte que le calcul (B*C)+(D*E) puisse s'effectuer en un cycle. Un additionneur (216) additionne les produits des deux multiplicateurs (260), (208). La somme de ces multiplicateurs est appliquée au premier accumulateur (220). De préférence, le second produit est également appliqué au second accumulateur (222) et un multiplexeur (128) applique soit un zéro, soit le second produit à l'additionneur (216). Si deux calculs indépendants doivent être effectués simultanément, c'est le zéro qui est appliqué et la sortie du second accumulateur est retournée à la pile de registres (PI2). Si un seul calcul (B*C) + (D*E) doit être effectué, c'est le second produit qui est appliqué à l'additionneur et la sortie du second accumulateur n'est pas prise en compte.

Title: Drive ring cvt belt
Inventor: YUAN JING
IPC: F16H9/10
Filed: 2001-03-16
Abstract: The invention conprises a drive ring CVT belt. In a CVT  transmis-sion, each variable diameter pulley (11, 12) as a drive ring (26, 36) trained around the sheaves. Each drive ring may comprise any high modulus material such as plas-tic or metal. An endless flexible tensile member or belt (10) is trained between the drive rings. Each drive ring further comprises a sleeve (7, 8) that is trained around an outer surface of each drive ring. Each sleeve slides in a bushing on its respective drive ring. The belt has a tensile load that presses each of the drive rings (26, 36) together on the sleeves. The relative arrangement of the axis of rotation of each drive ring (26, 36) is maintained by the contact between the sleeves (7, 8) and the drive rings. The effective diameter or radius of each pulley (11, 12) is adjusted by movement of each drive ring (26, 36) in each pulley. Movement of the pulley sheaves (22, 23, 32, 33) causes the axis of rotation of each drive ring to move ec-centrically with respect to the axis of rotation of the pulley. As the rings move, the belt moves with the drive rings and remains trained over the drive rings, giving a constant bending radius to the belt. The drive rings each may have a surface pro-file for use with flat belts, synchronous belts, toothed belts, multi-ribbed or v type belts.

Patent CA-2404769-A1 (CA)
Inventor: GU YUAN
IPC: G06F21/31
Filed: 2001-04-05
Abstract: If a user loses his password or pass phrase required for a computer or communication system, he must have some way of obtaining a new one. Typicall y, new passwords are provided to users manually, by another human, an approach that is expensive and insecure. The invention provides an automated solution  which allows recovery of secure access. The invention does this by complementary encryption of the user's pass phrase and responses to personal  questions, the reference responses being encrypted with the pass phrase and the pass phrase being encrypted with the reference responses. When a user loses his pass phrase, he can provide answers to the personal questions and the system will recover both the reference responses and the pass phrase, so  the account can be re-initialized by entering a new pass phrase. The inventi on also allows "approximate matching", so biometric data can be used for identification.

Inventor: HANNAWAY G WYNDHAM
IPC: H04N5/44
Filed: 2001-09-18
Abstract: A method for time-based synchronization of multiple media streams transmitted over a communications network, such as the Internet, by multiple, independent streaming media sources. First and second media streams of data packets are received from first and second media sources. Timing data is parsed from the two media streams, and first and second transmission delay values are determined by comparing the timing data with a reference time. A synchronized media stream is created by combining the first and second media streams into a time-synchronized media stream with adjustments to correct for calculated transmission delay values. Feedback signals are sent to the media sources to control transmission variables such as stream length, transmission rate, and transmittal time to manage the variable delay at the media source. The first and second media streams are decoded into intermediate media streams compatibly formatted to allow mixing of teh strams and data packets.
