    • A multi-bath apparatus and method for cooling a superconductor includes both a cooling bath comprising a first cryogen and a shield bath comprising a second cryogen. The cooling bath surrounds the superconductor, and the shield bath surrounds the cooling bath. The cooling bath is maintained at a first pressure and subcooled, while the shield bath is maintained at a second pressure and saturated. The cooling bath and the shield bath are in a thermal relationship with one another, and the first pressure is greater the second pressure. Preferably, the cryogens are liquid nitrogen, and the superconductor is a high temperature superconductor, such as a current limiter. Following a thermal disruption to the superconductor, the first pressure is restored to the cooling bath and the second pressure is restored to the shield bath in order to restore the superconductor to a superconductive state.
    • 用于冷却超导体的多浴装置和方法包括包括第一冷冻剂的冷却浴和包含第二冷冻剂的屏蔽浴。 冷却浴围绕超导体,屏蔽浴围绕冷却浴。 冷却浴保持在第一压力并过冷,同时屏蔽浴保持在第二压力并饱和。 冷却浴和屏蔽浴彼此处于热关系,第一压力大于第二压力。 优选地,冷冻剂是液氮,超导体是高温超导体,例如限流器。 在对超导体的热破坏之后,将第一压力恢复到冷却浴,并且将第二压力恢复到屏蔽浴,以将超导体恢复到超导状态。

    • A method for authentication of a first client in communication with a second client via an authentication server is disclosed, such that the first client and the second client are authenticated to each other, and the authentication server is authenticated to both the first client and the second client. The ability of a client and an authentication server to generate a one-time-use key unique to the client for a given request, is used as the basis for authentication. The flow of requests and responses coupled with each client's unique one-time-use key, such as a one time use account number used to encrypt messages, results in all three entities, the two clients and the authentication server, mutually authenticating each other. The method effectively prohibits a “man-in-the-middle” attack, wherein an unauthorized entity tries to assume the roll of one of the two clients, or the authentication server.
    • 公开了一种用于经由认证服务器与第二客户端通信的第一客户端的认证方法,使得第一客户端和第二客户端彼此认证,并且认证服务器被认证到第一客户端和第二客户端 客户。 客户端和认证服务器为给定请求生成客户端特有的一次性密钥的能力被用作认证的基础。 每个客户端唯一的一次性密钥(例如用于加密消息的一次性使用帐号)的请求和响应的流程导致所有三个实体,两个客户端和认证服务器彼此相互认证。 该方法有效地禁止“中间人”攻击,其中未经授权的实体试图假定两个客户端之一的卷或验证服务器。
