Abstract: Disclosed is a system that adapts a personally portable “smart” communications device to enhance a user's personal security by continuously monitoring an alert function of the device from a remote location during a user initiated “session.” The user device is in communications with a remote server, which monitors the alert function and provides: accurate preservation of session data; monitoring of user device ambient conditions; dispatch of emergency services; and notification of third parties. Server software (host application) on the remote server manages communications with user devices. The server collects, processes and stores data; dispenses data according to a rule set, and manages multiple user sessions. User software manages the initiation and conduct of a session and communications with the server. The user and server software in combination provide for establishing, maintaining operations of the system, and databases accessible by the remote server for storage/archiving of system data.

Abstract: Systems for storage system rollover and rollback. A data mover agent is installed on a source storage system to capture disaster recovery data and send to a target system. Upon receiving a rollover event signal, a virtualized controller creates one or more replica user virtual machines running on the target system that serve to replicate functions of the user virtual machines from the source storage system.

Rollback is initiated when the target system receives a rollback event signal. Differences in the data that have occurred between the rollover event and the rollback signal are calculated and sent to the rollback system. The calculated differences are applied to a registered snapshot on the rollback system.

Abstract: A user device has a processing module and a UI module. The processing module may have a permanent connection to the UI module, and an intermittent connection to a content management system over a data network. User requested actions are executed within the UI module. For each such action, a parallel request is sent to the content management system when network connectivity allows. Results of the user requested actions are presented within the UI module as if they had been implemented on the content management system. The user may thus interact with content as if all user requested actions have occurred substantially simultaneously with the request. When network connectivity allows, confirmation is received in the processing module from the content management system that the actions have been implemented, and the state of the user requested actions in the UI module is matched with that on the content management system.

Abstract: A technique is applied to eventually converge on a single data storage strategy for any set of object data which had an inconsistent data storage strategy applied during storage while there was a network partition. This state could occur in instances of a highly available distributed object storage system which can store objects according to multiple data storage strategies. Upon the healing of a network partition, the technique discovers if multiple data storage strategies were applied to the object data stored during a network partition, deterministically identifies which data storage strategy represents the correct strategy, for example based on the log of state transitions requested by the client according to the API contract, and ensures that this strategy is consistently applied to all object data in the collection.

Multiple option blocks may be included in the synchronization command to specify the synchronization of multiple classes. Where multiple classes are specified, the server responds with the synchronized items of all such classes while maintaining each class's unique schema.
