    • Provided is a two-actor user authentication system with a reduced risk of leakage of authentication information.The two-factor user authentication system is designed to use, as a password, a one-time-password derivation rule to be applied to certain pattern elements included in a presentation pattern at specific positions so as to create a one-time password, and further use, as a second authentication factor, information identifying a client to be used by a user. An authentication server is operable to generate a pattern seed value adapted to uniquely specify a presentation pattern in combination with a client ID, and transmit the pattern seed value to an authentication-requesting client. The authentication-requesting client is operable to create a presentation pattern based on a client ID acquired therefrom, and display the presentation pattern to allow a user to enter thereinto a one-time password based on the presentation pattern.
    • 提供了一种具有降低认证信息泄漏风险的双重角色用户认证系统。 双因素用户认证系统被设计为使用一次性密码导出规则来应用于特定位置处的呈现模式中包括的某些模式元素,以便创建一次性密码,以及 作为第二认证因素,进一步使用标识用户要使用的客户端的信息。 验证服务器可操作以产生适合于与客户端ID结合唯一地指定呈现模式的模式种子值,并将模式种子值发送到认证请求客户端。 认证请求客户端可操作以基于从其获取的客户端ID创建呈现模式,并且显示呈现模式以允许用户基于呈现模式进入一次性密码。

    • In a gas combustion type fastener driving machine, a fuel gas and air are stirred by a fan within a combustion chamber, a stirred air-fuel gas mixture is burned by an ignition spark, and a striking piston is actuated by a combustion pressure to drive a fastening member. The machine is provided with a fan motor (320) for rotating the fan, and a control circuit board (100) for controlling an action of the fan motor (320). The control circuit board (100) detects an actuation signal for an igniter (310) that generates the ignition spark and controls a rotation speed of the fan motor (320) based on the actuation signal.
    • 在气体燃烧型紧固件驱动机中,燃料气体和空气由燃烧室内的风扇搅拌,搅拌的空气 - 燃料气体混合物通过点火火花燃烧,并且打击活塞由燃烧压力驱动以驱动 紧固件。 该机器设置有用于使风扇旋转的风扇马达(320),以及用于控制风扇马达(320)的动作的控制电路板(100)。 控制电路板(100)检测产生点火火花的点火器(310)的致动信号,并根据该致动信号控制风扇马达(320)的转速。
