    摘要： A remote intelligent communications device includes a primary RF communications port and an alternative modem communications port. The remote intelligent communications device receives configuration data for configuring the alternative modem communications port. The remote intelligent communications device obtains information data concerning a select attribute of an associated object. The information data is stored within internal memory of the remote intelligent communications device. Thereafter, the stored information data is retrieved, per one embodiment via the alternative modem port, from the remote intelligent communications device and analyzed for drawing conclusions regarding the select attribute of the associated object. Preferably, the remote intelligent communications device also includes a navigation (e.g. GPS) receiver that obtains navigation data, which navigation data is also stored within the internal memory of the remote intelligent communications device. By storing this navigation data together with the information data, once the stored data is retrieved from the remote intelligent communications device, the information data and navigation data can be analyzed for correlating the select attribute of the associated object with respective geographic position in accordance with the analyzed information and navigation data. In one exemplary application, the specific attribute is an open/close condition of a door of a cargo bay, monitored by an appropriate transducer disposed functionally proximate thereto.

    摘要： A protocol is used to coordinate the use of a common communication medium by one or more interrogating commander stations and an unknown plurality of responding responder stations. Each commander station and each responder station is equipped to broadcast messages and to check for error in received messages. When more than one station attempts to broadcast simultaneously, an erroneous message is received and communication is interrupted. To establish uninterrupted communication, a commander station broadcasts a command causing each responder station of a potentially large first number of responder stations to each select a random number from a known range and retain it as its arbitration number. After receipt of such a command, each addressed responder station transmits a response message containing its arbitration number. Zero, one, or several responses may occur simultaneously. By broadcasting requests for identification to various subsets of the full range of arbitration numbers and checking for an immediate error-free response, a commander station can determine the arbitration number of every responder station capable of communicating at the time. Consequently, a commander station can conduct subsequent uninterrupted communication with each responder station, for example by addressing only one responder station. Responder stations of this invention require minimal logic and circuitry to respond to multiple commander stations.
