    • A first hash result is generated at a client system in accordance with hash input parameters known to the client system. A second hash result is generated at a server system in accordance with hash input parameters known to the server system. Each of the first hash result and the second hash result is truncated in a same manner. The truncated first hash result is transmitted from the client system to the server system. The truncated first hash result as transmitted to the server system is compared with the truncated second hash result generated at the server system. Equality between the truncated first hash result as transmitted to the server system and the truncated second hash result generated at the server system authenticates the client system to the server system.
    • 根据客户端系统已知的散列输入参数,客户机系统产生第一个散列结果。 根据服务器系统已知的散列输入参数,在服务器系统产生第二散列结果。 第一个哈希结果和第二个哈希结果中的每一个以相同的方式被截断。 截断的第一个哈希结果从客户端系统传输到服务器系统。 传输到服务器系统的截断的第一个哈希结果与在服务器系统生成的截断的第二哈希结果进行比较。 发送到服务器系统的截断的第一个散列结果与在服务器系统产生的截断的第二个散列结果之间的等价性将客户端系统认证到服务器系统。

    • A sending device generates a MAC frame to be transmitted over a wireless network. The MAC frame indicates a frame transmission type. A payload portion of the MAC frame is defined in accordance with a payload specification of a distributed asset management protocol corresponding to the indicated frame transmission type. The MAC frame is transmitted over the wireless network and received by a receiving device that is defined to recognize the MAC frame as the indicated frame transmission type. The receiving device is defined to process the payload portion of the MAC frame in accordance with the payload specification of the distributed asset management protocol corresponding to the indicated frame transmission type. Network discovery includes successively transmitting the MAC frame at a defined interval during a first period of time. Then, the MAC frame transmission is ceased for a second period of time. Then, transmission of the MAC frame resumes.
    • 发送设备生成要通过无线网络发送的MAC帧。 MAC帧表示帧传输类型。 根据与所指示的帧传输类型相对应的分布式资产管理协议的有效载荷规格来定义MAC帧的有效载荷部分。 MAC帧通过无线网络发送并由接收设备接收,接收设备被定义为将MAC帧识别为所指示的帧传输类型。 接收设备被定义为根据与所指示的帧传输类型相对应的分布式资产管理协议的有效载荷规格来处理MAC帧的有效载荷部分。 网络发现包括在第一时间段内以规定的间隔连续发送MAC帧。 然后,MAC帧传输停止第二个时间段。 然后,MAC帧的传输恢复。

    • An unknown named territory encloses a known physical target location that is specified by a target longitude and a target latitude. An operation is performed to identify a number of rectangular-shaped terrestrial areas that each enclose both the target longitude and the target latitude. Each of the identified rectangular-shaped terrestrial areas respectively encloses a polygonal-shaped named territory. Each polygonal-shaped named territory is defined by a respective circumscribing set of contiguously positioned vectors. An operation is performed to evaluate the circumscribing sets of contiguously positioned vectors of the polygonal-shaped named territories to determine if a given polygonal-shaped named territory includes both the target longitude and the target latitude. When both the target longitude and the target latitude are found to reside within a given polygonal-shaped named territory, the identity of the given polygonal-shaped named territory is conveyed.

    • Monitoring data is received from a remote device and represents a current status value of a monitored condition at the remote device. The monitored condition is characterized by a current state that can be any one of a number of possible states. A determination is made as to whether the current status value of the monitored condition as indicated by the received data satisfies a hysteresis criterion associated with the current state of the monitored condition. If the current status value of the monitored condition satisfies the hysteresis criterion, then a determination is made as to whether the hysteresis criterion has been continuously satisfied for a specified persistence period. If the hysteresis criterion has been continuously satisfied for the specified persistence period, then the current state of the monitored condition is changed to reflect the current status value of the monitored condition, and the changed current state is recorded.
    • 从远程设备接收监视数据,并表示远程设备上监视条件的当前状态值。 监视条件的特征在于可以是多种可能状态中的任何一种的当前状态。 确定由接收到的数据指示的监视条件的当前状态值是否满足与监视条件的当前状态相关联的滞后准则。 如果被监视条件的当前状态值满足迟滞准则,则确定在指定持续时间段内是否已经连续满足滞后判据。 如果在指定的持续时间内已经持续满足迟滞准则,则监视条件的当前状态被改变以反映被监视条件的当前状态值,并记录改变的当前状态。
