Abstract: The effect of a windshield for a saddle-type vehicle such as a low-slung type of motorcycle or three-wheeled vehicle is enhanced, and pressure is sufficiently adjusted in an open space at the back of the windshield using an inventive windshield system. The vehicle includes a leg shield in front of legs of a rider, and a step space rearward of the leg shield. The windshield system includes a windshield which is provided with an air outlet that opens upward. An air inlet provided at the front of the vehicle communicates with the air outlet other through a duct, and the air outlet opens to the upper center of the windshield. Pressure adjusting outlets, for adjusting pressure in a space around the rider by blowing air toward the step space, are provided separately from the air outlet.

Abstract: Disclosed is an off-line user authentication system, which is designed to present a presentation pattern to a user subject to authentication, and apply a one-time-password derivation rule serving as a password to certain pattern elements included in the presentation pattern at specific positions so as to create a one-time password. An off-line authentication client pre-stores a plurality of pattern element sequences each adapted to form a presentation pattern, and a plurality of verification codes created by applying a one-time-password derivation rule to the respective presentation patterns and subjecting the obtained results to a one-way function algorithm. A presentation pattern is created using one selected from the stored pattern element sequences, and presented to a user. A one-time password entered from the user is verified based on a corresponding verification code to perform user authentication. The present invention provides an off-line matrix authentication scheme with enhanced security.

Abstract: To provide an air-inlet structure of a motorcycle in which air-inlet ducts can be connected to an air box without providing through holes for allowing passage of the air-inlet ducts on the main frame or bending the air-inlet ducts to bypass a main frame. An engine is supported on a pair of left and right front frames that extend from a head pipe that supports a front wheel rearward and downward. An air box supplies air to the engine and is arranged above the engine. Air-inlet ducts introduce air to the air box and extend on the outer sides of the front frames in a fore-and-aft direction of a vehicle body to be connected to an air-inlet port of the air box at the back of the front frames.

An off-line authentication client pre-stores a plurality of pattern element sequences each adapted to form a presentation pattern, and a plurality of verification codes created by applying a one-time-password derivation rule to the respective presentation patterns and subjecting the obtained results to a one-way function algorism. A presentation pattern is created using one selected from the stored pattern element sequences, and presented to a user. A one-time password entered from the user is verified based on a corresponding verification code to perform user authentication. The present invention provides an off-line matrix authentication scheme with enhanced security.

Abstract: A windshield device for obtaining a favorable screen effect with respect to an air flow from the sides of a screen while suppressing large-sizing of the screen in the vehicle width direction. In a front cowling which includes a screen unit which is mounted on a front portion of a vehicle body and has a screen, an air introducing opening is formed in a front portion of the screen unit and opens forwardly. An air blow-off opening is formed in an upper portion of the screen unit that opens upwardly. An air duct allows the screen unit and the air blow-off opening to communicate with each other. Air discharge ports which open outwardly and to the sides from the vehicle are formed in a side of the air duct.

Abstract: A power transmission mechanism of a motorcycle includes a drive case which is disposed at the rear end of and outside of a rear swing arm, and which surrounds the axle of a rear wheel and incorporates a transmission device. In addition, the power transmission mechanism includes a drive shaft extending from an output shaft of an engine for transmitting power of the drive shaft to the rear wheel. The transmission device converts the direction of a driving force of the drive shaft and transmits it to the rear wheel. The drive shaft constituting part of the power transmission mechanism is disposed below the rear swing arm and the pivot shaft. The result is a motorcycle configuration that suppresses the vehicle width without expanding the rear swing arm.

Abstract: A motorcycle with a low floor is configured such that secondary vibration of an engine can be largely reduced and an increase in engine width can be suppressed. The motorcycle with a low floor includes step floors on which to put a rider's feet on left and right sides of a vehicle body frame. An engine is provided between the step floors. A plurality of exhaust pipes extend respectively from cylinders of the engine, the exhaust pipes being gathered at a gathering portion. The engine is an in-line 3-cylinder engine having cylinder portions inclined forwardly. The exhaust pipes extend downwards from the cylinder portions on the basis of each cylinder. The exhaust pipes are bundled and extend on the right side of the engine, in a position on the lower side of one of the step floors.

Abstract: Disclosed is a user authentication system, which is designed to present a presentation pattern to a user subject to authentication, and apply a one-time-password derivation rule serving as a password of the user to certain pattern elements included in the presentation pattern at specific positions so as to create a one-time password. An authentication server is operable to generate a pattern seed value adapted to be combined with a user ID so as to allow a presentation pattern to be uniquely determined, and transmit the generated pattern seed value to an authentication-requesting client. The authentication-requesting client is operable to display a presentation pattern created based on an entered user ID and the received pattern seed value and in accordance with a given pattern-element-sequence creation rule, so as to allow the user to enter therein a one-time password, and transmit the entered one-time password to the authentication server.

Abstract: A motorcycle includes at least a first auxiliary member mounted on a body of the motorcycle for contacting a road and providing assistance to the motorcycle body to support itself, when necessary, and a second auxiliary member mounted on the motorcycle body, wherein the second auxiliary member is inflatable, in order to contact the road to support the motorcycle body, in addition to the first auxiliary member.
