Abstract: A safety architecture system includes, in one aspect, a first stage comprising a primary unit that generates primary data for performing normal system functionality; a secondary unit that generates secondary data for performing alternative system functionality; a primary safety gate coupled to the primary unit, with the primary safety gate providing the primary data as a primary output responsive to a determination of validity of the primary data; and a secondary safety gate coupled to the secondary unit, with the secondary safety gate providing the secondary data as a secondary output responsive to a determination of validity of the secondary data. The system also includes an output selector that is coupled to both the primary safety gate and the secondary safety gate of the first stage, with the output selector providing a system output responsive to the determinations of the validities of the primary data and the secondary data.

Abstract: A method and system for connecting proximately located telecommunications units are disclosed. The method and system may be used in a location aware telecommunications system that can determine the location of a telecommunications unit (TU) being used within the system. A user of a mobile telecommunications unit (MU) is connected to a TU when the MU is within a predetermined distance of a predetermined geographic location meeting predefined criteria. The TU to which the MU is connected may be automated or manually operated. In some embodiments, multiple MUs are connected when they are within a predetermined proximity to each other and a predefined criteria is met.

Abstract: Accurate location information about a mobile telecommunication transceiver is used to generate advertising content responsive to a user approaching the location of a business. This advertising content is tailored to the user's preferences and the particular business involved. Once the advertising content is delivered, the position of the user is monitored to track the effectiveness of the advertisement. If the user enters the business' store and/or makes a purchase, the advertisement is logged as having been successful. If the user does not enter the store within a predetermined period of time or moves away from the store, the advertisement is considered to have been ineffective.

Abstract: A method and system for connecting proximately located telecommunications units are disclosed. The method and system may be used in a location aware telecommunications system that can determine the location of a telecommunications unit (TU) being used within the system. A user may be connected to one or more other users when they have compatible attributes and when they are located within a predetermined distance of each other. The connection may be established between TUs of two or more users, based on attribute and distance information maintained by a server computer, upon the request of an initiating user's TU.

Abstract: A method and system for selectively connecting proximately located telecommunications units are disclosed. The method and system may be used in a location aware telecommunications system that can determine the location of a telecommunications unit (TU) being used within the system. A first TU may be connected to a second TU when the first and second TUs are within a predetermined distance of each other and when a first user associated with the first TU may be connected to a second user associated with the second TU on a graph representing individual relationships, such as an acquaintance graph or genealogical tree. The connection may further be based on whether the first and second users have a less than a maximum threshold degree of separation within the relationship graph.
