    • The invention relates to a regional lawn maintenance management system and method, and relates to the technical field of lawn maintenance management, mainly including lawn maintenance terminal equipment, evaluation equipment, intelligent computing equipment, community terminal equipment, data visualization equipment, connected through a communication network, the management equipment, database and commercial operation equipment can fully evaluate the users condition before the user conducts regional lawn maintenance management. The intelligent computing equipment and evaluation equipment generate suitable data based on the evaluation data information and/or historical evaluation data information before, and after the maintenance of the lawn based on the users maintenance plan information and feedback from the lawn maintenance terminal equipment, the maintenance plan information is continuously optimized in subsequent maintenance or data processing to generate a set of targeted maintenance plans, and the comparison is obtained at the regional level. The macro regional turfgrass data provides the function of regional turfgrass maintenance and decision-making, so that turfgrass management can be regionalized, refined, intensive and intelligent.

    • Systems, methods, and other embodiments associated with flexible supplicant access control are described. One example method includes collecting a network information associated with a network to which an endpoint is to be communicatively coupled. The network information comprises a network identification and information to facilitate the evaluation of network threats. The example method may also include classifying the network based, at least in part, on the network information, to assign a variable level access parameter (VLAP) to the network based on the policy locally configured on the endpoint or centrally managed by the administrator. The VLAP may establish three or more access levels for the network at the endpoint. The example method may also include communicating the network identification and the network VLAP to a second endpoint, a security agent, a security application, and so on.
    • 描述了与灵活请求者访问控制相关联的系统,方法和其他实施例。 一个示例性方法包括收集与端点将要通信耦合到的网络相关联的网络信息。 网络信息包括网络标识和信息,以便于评估网络威胁。 该示例性方法还可以包括至少部分地基于网络信息对网络进行分类,以基于在端点上本地配置的策略或由管理员集中管理的策略向网络分配可变级访问参数(VLAP)。 VLAP可以在端点处为网络建立三个或更多个访问级别。 示例性方法还可以包括将网络标识和网络VLAP传送到第二端点,安全代理,安全应用等。

    • A method of providing automatic frequency control pull-in for efficient receipt of GLONASS bits is described. This method can include first determining whether a channel noise (CNo) is greater than or equal to a predetermined value. When the CNo is greater than or equal to the predetermined value, the pull-in can be performed using a first series of predetection integration periods (PDIs) with activated decision-directed flips (DDFs) until a 20 ms boundary of a GLONASS data bit is found. When the CNo is less than the predetermined value, the pull-in can be performed using a second series of PDIs with always deactivated DDFs. A similar method of providing automatic frequency control pull-in for efficient receipt of GPS bits is also described.
    • 描述了提供自动频率控制拉入以有效接收GLONASS位的方法。 该方法可以包括首先确定信道噪声(CNo)是否大于或等于预定值。 当CNo大于或等于预定值时,可以使用具有激活的决策导向翻转(DDF)的第一系列预检整合周期(PDI)来执行引入,直到GLONASS数据位的20ms边界 被发现。 当CNo小于预定值时,可以使用具有永久禁用的DDF的第二系列PDI来执行引入。 还描述了提供自动频率控制拉入以有效接收GPS位的类似方法。

    • A method of determining a distance between a first wireless device and a second wireless device is provided. In this method, a location symbol can be generated by filtering and modulating a pseudorandom (PRN) code. The location symbol can be provided in a data field of a legacy wireless packet to form a first location packet. The first location packet can be transmitted from the first wireless device to the second wireless device. A second location packet can be transmitted from the second wireless device to the first wireless device, wherein the second location packet is substantially identical to the first location packet. An effective roundtrip time between the first and second wireless devices can be determined based on the first and second location packets. The distance between the first and second wireless devices can be computed using this roundtrip time.
