To enhance convenience in an authentication system using a plurality of types of authentication, a terminal device transmits authentication data including a face image and a voice of a user, the position of the terminal device, to the server device. The server device uses the received authentication data to perform individual authentications including face authentication, voiceprint authentication, position adequacy verification. The server device applies adds up weighted scores of the individual authentications to calculate a comprehensive score. When the comprehensive score exceeds a first threshold, a high security operation is permitted. When the comprehensive score is not higher than the first threshold and exceeds a second threshold, a low security operation is permitted. When performing additional authentication using additional authentication data received from the terminal device, the comprehensive score further includes the additional authentication score, and the high security operation is permitted when the comprehensive score exceeds the first threshold.

Authentication system and authentication method

A gas generator for slowly inflating an air bag at the early stage of the inflation and then rapidly inflating it or discharge a clean gas evenly around a housing. The gas generator includes a gas generating agent () and an squib () in the housing (). The squib () is disposed eccentrically to the axis (a) of the housing (). A high temperature gas is generated in a combustion chamber () because of the combustion of the gas generating agent () ignited by the squib (). The permeability of the high temperature gas through inner cylindrical member () closest to the squib () is lower than that through the part other than the inner cylindrical member ().

Gas generator

It is an object of the present invention to provide a gas generator suitable for an organic-compound gas generating agent and excellent in heat resistance, pressure resistance, and sealing. In the gas generator, a housing () is formed by joining an iron- or steel-made upper lid (), consisting of a top plate () and a side cylinder () extending downward from an entire circumferential edge thereof and provided with many gas discharge holes () with an iron- or steel-made lower lid (), consisting of a bottom plate (), side cylinder () extending upward from an entire circumferential edge thereof, and an ignitor holding portion () formed integrally with the bottom plate () and for fixing by caulking an ignitor (). In the housing (), the ignitor () and a gas generating agent () are arranged in the order mentioned from a center thereof.

It is the object of the present invention to provide a gas generator that can provide a controlled expansion and inflation of the airbag with improved reliability. The gas generator D of the present invention is so structured that gas generating agents packed in combustion chambers can be burnt by two ignitors independently of each other, wherein the ignitors electrically ignite ignition agents by use of bridge wires for generating heat by electrifying, and resistance values thereof are differentiated from each other.

A seat belt retractor is formed of a frame, a reel rotationally supported by the frame for winding a seat belt, a reel urging device connected to the reel for urging the reel in a seat belt winding direction, a locking device provided between the frame and the reel for allowing the reel to rotate freely in a normal state and preventing the reel to rotate in a belt unwinding direction when necessary, and a belt tension control mechanism for controlling a belt tension of the seat belt. The belt tension control mechanism includes a motor, and a power transmission path situated between the motor and the reel and actuated by the motor. The power transmission path has an OFF-state in which a rotational torque of the motor is not transmitted between the motor and the reel, and an ON-state in which the rotational torque is transmitted between the motor and the reel. A power transmission path switching mechanism selectively switches the power transmission path between the ON-state and the OFF-state. The belt tension control mechanism is simplified by reducing the number of the components.

Seat belt retractor

A gas generator for air bags for use in an air bag system for safely protecting a driver and riders in a vehicle from shock from collisions at low cost, while preventing slag in a gas flowing outside. The gas generator includes a housing ( ) formed by a side cylinder ( ) with a plurality of gas exhaust openings ( ) the housing being closed at its ends by an upper cap ( ) and a lower cap ( ); an igniting device ( ), provided in the housing ( ) at a center portion thereof; gas generating agents ( ), provided in the housing ( ) at a location radially outside of the igniting device ( ), to be burnt to generate gas; a cooling/filtering member ( ) provided in the housing ( ) at a location radially outside of the gas generating agents ( ) to enclose the gas generating agents and extending from the side of the upper cap ( ) to the side of the lower cap ( ); and an annular projection ( ) for preventing the gas generated by the burning of the gas generating agents ( ) from flowing toward an end portion of the cooling/filtering member ( ). The annular projection ( ) is integrally formed on at least one of the upper cap ( ) and the lower cap ( ) so as to abut with an inner peripheral surface of the cooling/filtering member ( ).
