    • A method of forming an ad hoc hierarchical communication network among a plurality of wireless transceiver includes assigning to each of the transceivers one or more common designations. A network organization routine of the transceivers operates to establish hierarchical networks based on the transceivers' common designations, resulting in a logical network organization that provides efficiencies for acquiring information from particular transceivers that share a common designation. Each transceiver's common designation is used by a digital processor of the transceiver to selectively receive data packets that are intended for receipt by transceivers sharing the particular common designation. Such a “common designation” network reduces power consumption and signal interference, which increases battery life in the transceivers. The transceivers may include a query handling routine in communication with a memory of the transceiver for serving as a dynamic distributed hierarchical database system of information such as, for example, sensor-derived information and time-sensitive information.
    • 在多个无线收发器中形成自组织分层通信网络的方法包括向每个收发机分配一个或多个通用名称。 收发器的网络组织程序用于基于收发器的通用指定来建立分层网络,从而形成逻辑网络组织,其提供用于从共享共同标识的特定收发器获取信息的效率。 每个收发器的公共名称由收发器的数字处理器使用以选择性地接收旨在由共享特定公共名称的收发器接收的数据分组。 这种“通用名称”网络降低了功耗和信号干扰,从而增加了收发器的电池寿命。 收发机可以包括与收发器的存储器通信的查询处理例程,用作动态分布式分层数据库系统的信息,例如传感器导出信息和时间敏感信息。

The electronic components are arranged and configured such that the device operates in at least two states. In the first state, the device responds to a Present Broadcast by making a Present Response. In the second state, the device does not respond to a Present Broadcast with a Present Response. The electronic components further are arranged and configured such that the device enters the second state from the first state upon responding to a Present Broadcast with a Present Response, and such that the device enters the first state from the second state upon receiving, through the interface, one or more sensor signals based on sensor-acquired data that is indicative of a predetermined condition.

    • A system and method are disclosed for determining a position of a wireless communication device. A method includes determining a respective (x,y) position of two wireless communication devices, determining a distance between the two wireless communication devices, and determining a relative elevational differential between the two wireless communication devices. The relative elevational differential is determined based on the determined (x,y) positions of the two wireless communication devices and the determined distance between the first and second wireless communication devices. The (x,y) positions may be determined using GPS receivers incorporated in the wireless communication devices. Determining the distance between the devices may be accomplished using RF ranging. The relative elevational differential may be derived using the Pythagorean theorem.
