Abstract: A central server outside of a school network receives assignments from educator computing devices, where each assignment includes content for distribution to student computing devices and a schedule indicating when the assignment is active for distribution. A local server within the school network receives the assignments and stores the assignments in a local server datastore. The local server receives from a gateway within the school network a request for active assignments, identifies the active assignments, and returns a list of the active assignments to the gateway. The gateway determines whether the list of the active assignments contains any assignments unretrieved by the given gateway. If so, the gateway sends to the local server a request for the unretrieved assignments. The gateway receives the requested assignments from the local server and stores them in a gateway datastore.

Abstract: A system for flexibly targeting information sent over a broadcast communications medium includes a sender of information signals each carrying information and a targeter for use by a user having a receiver with a targeter. There are a number of the receivers constructed and arranged to receive signals from the sender through a broadcast communications medium. The targeter includes a number of selectors associated with an action ID and a number of key value pairs, constructed and arranged to indicate action to be taken by a user of a selected receiver in the condition that the selector evaluates to true given the values stored in the targeters.

Abstract: Two or more communications applications are executed on a shared processing platform to process signals received from and transmitted to wireless devices according to a communications protocol, the shared processing platform having shared hardware resources including memory and at least one data processor. A security mechanism is provided to enable each communications application to have independent control of access to data and configuration settings that are private to the communications application. Compatibility of hardware configuration settings associated with different communications applications is determined, and conflicts between hardware configuration settings associated with different communications applications are mediated.

Abstract: In some aspects, a method includes characterizing a communication link established over a network between a home base station and a base station controller. The home base station is configured to send signals to one or more mobile devices and receive signals from the one or more mobile devices. The method also includes determining a level of service to provide by the home base station to the one or more mobile devices based on the characterization of the communication link.

Abstract: In some aspects, a method includes determining a location of the home base station. The method also includes determining if the communication carrier has a spectrum license in the determined location. If the communication carrier does not have a spectrum license in the determined location, the method also includes leasing a portion of a frequency spectrum from another carrier that has a spectrum license in the determined location.

Abstract: Methods and systems for allocating mobiles among multiple frequency channels in a mobile communications system are disclosed.

Abstract: In one aspect, the invention is a method for allocating channels. The method includes determining a communication standard used by a message and determining available channels. The method also includes allocating a channel based on the available channels and the communication standard used by the message. The method may also include sending an instruction to use the channel.

Abstract: A method and apparatus for receiving and relaying signals from an ignition coil. A secondary pickup is constructed and arranged to mate with the ignition coil and to receive the secondary voltage signals. The signals can be received and relayed to an analyzer for engine evaluation through a spade that is part of the secondary pickup.
