    • The embodiments of herein provide a permission based field service management system and method for field services using a permission slip. A technician allotted to perform a field service is authenticated by a client/server software system and provided with a work list. When the technician accepts a work list, a permission slip corresponding to a specific device is entered in a service key inserted by the technician into a client. Then the service key is removed and inserted into a specific device to execute a field service operation. After the completion of the field service operation, the permission slip is closed and a service log is created and stored on a service database. An auditing system accesses the service data to track and monitor the service operation.
    • 本文的实施例提供了一种基于许可的现场服务管理系统和使用许可单的现场服务的方法。 分配用于执行现场服务的技术人员由客户端/服务器软件系统认证并提供工作列表。 当技术人员接受工作列表时,将与特定设备相对应的许可单据输入到由技术人员插入客户端的服务密钥中。 然后删除服务密钥并将其插入到特定设备中以执行现场服务操作。 在现场服务操作完成后,权限单关闭,服务日志被创建并存储在服务数据库中。 审计系统访问业务数据,跟踪监控业务运行。

    • The present invention relates to a viscous shear coupling (e.g. for use as a fan drive comprising an annular driving member, usually in the form of a disc having a hub portion for mounting on a driving shaft, a driven member having an internal annular chamber receiving said annular driving member, with facial planar and circumferential surfaces of said chamber and opposing facial planar and circumferential surfaces of said driving member at least in part being in close-spaced relationship, said driven member being axially and radially located for rotation relative to said driving member, viscous coupling fluid in said chamber, and a 0.0005 to 0.0015 inch thick layer of non-metallic anti-friction material on at least those parts of said facial planar and circumferential surfaces of said annular chamber which are in close spaced relationship, thereby forming journal and thrust bearing means for the relative rotation of the driving member and the driven member.
    • 本发明涉及一种粘性剪切耦合器(例如,用作风扇驱动器,其包括环形驱动构件,通常为具有用于安装在驱动轴上的毂部的盘形式,其具有内部环形室接收的从动构件 所述环形驱动构件具有所述腔室的面部平面和圆周表面,并且所述驱动构件的相对面向平面和圆周表面至少部分地处于紧密间隔的关系中,所述从动构件被轴向和径向地定位成相对于所述驱动 在所述室中的粘结耦合流体,以及在所述环形室的所述面部平面和周向表面的至少那些部分上的0.0005至0.0015英寸厚的非金属抗摩擦材料层,其间隔间隔开,从而形成 用于驱动构件和从动构件的相对旋转的轴颈和推力轴承装置。
