Patent CA-2394311-A1 (CA)
Inventor: WOODHILL JAMES R
IPC: G06Q20/40
Filed: 2000-12-14
Abstract: An authentication or authorization system to facilitate electronic transactions uses simultaneous or substantially simultaneous communications on two different networks to verify a user's identity. When a user logs (V) onto a site, via the internet, a telephone number (46), either pre-stored or obtained in real time from the visitor (V), where the visitor (V) can be called essentially immediately is used to set up, via the switched telephone network (44) another communication link. Where the user (V) has multiple communication links available, the telephone call is automatically placed via the authentication or authorization software (38) simultaneously while the user (V) is on-line. In the event that the user (V) has only a single communication link, that individual will have to log off temporarily for purposes of receiving the telephone call (46). Confirmatory information is provided via the internet to the user. The automatically placed telephone call (46) requests that the user (V) feed back this confirmatory information for verification purposes. The telephone number which is being called is adjacent to the user's internet terminal. The user's response, via the telephone network (46), can be compared to the originally transmitted confirmatory information to determine whether the authentication or authorization process should go forward.

Title: Transmitting/receiving apparatus and method for packet retransmission in a mobile communication system
Inventor: CHOI GIN-KYU
IPC: H04J13/10
Filed: 2002-10-29
Abstract: A transmitting/receiving apparatus and method for packet retransmission in a mobile communication system. Upon request for a retransmission from a receiver, a transmitter generates first coded bits by inverting initially transmitted coded bits, generates second coded bits by separating the initially transmitted coded bits into a first bit group having a relatively high priority and a second bit group having a relatively low priority and exchanging the first bit group with the second bit group, and generates third coded bits by inverting the exchanged coded bits. The transmitter selects one of the first coded bits, the second coded bits according to the sequence number of a retransmission request received from the receiver, and the third coded bits and maps the selected coded bits to modulation symbols. The transmitter then transmits the modulation symbols to the receiver.

Abstract: A ride quality simulator (1) for evaluating a ride quality of railway accurately, comprising a controller (60) for controlling a driver (50) to shake a plurality of arbitrary shafts simultaneously among six shafts for a passenger room (10) simulating the interior of a railway vehicle. The controller (60) sets an upper limit on the vibratory acceleration and the frequency region of a back/forth component of a vibration applied to the simulated passenger room (10) out of a up/down component, a left/right component and a back/forth component, to thereby raise the upper limits on the vibratory accelerations and the frequency regions of the up/down component and the left/right component. Since a ride quality can be reproduced, when the vibration is divided into an up/down component, a left/right component and a back/forth component, to such respective extents as giving very poor ride qualities, the ride quality simulator (1) can evaluate a ride quality accurately.
