    • A stolen asset locating and recovery system comprises: a first locating device (LD) associated with a first asset. The first LD has a first wireless communication unit comprising a public mobile radio network (PMRN) enabled communication unit for communicating over a PMRN such as a GSM/GPRS network with any of: an operations control center; a second LD associated with a second asset; or a mobile location tracking system. The first LD has a second wireless communication unit. The second wireless communication unit uses a different wireless technology or protocol to that of the PMRN enabled communication unit. In the case where the second communication unit is a private radio frequency network (PRFN) operated by the asset location system service provider, the first LD is configured to use said second communication unit to communicate directly over said PRFN with the second LD in order to convey information such as a preprogrammed sequence of signals which assists locating and recovering said asset. In the event that the second communication unit is enabled for communication on a public radio network (PRN), the first LD is configured to communicate with any of the operations control center, the second LD, or the mobile location tracking system on a PRN such as an IEEE802.11 enabled wireless local area network (WLAN) or an IEEE802.16 enabled wireless metropolitan area network when it is determined at the first LD that the communication cannot be transmitted between said first LD and any of the operations control center, the second LD, or the mobile location tracking system using the PMRN.

    • For use with an active database stored in volatile memory for direct revision thereof, the active database having multiple checkpoints and a stable log, having a tail stored in the volatile memory, for tracking revisions to the active database to allow corresponding revisions to be made to the multiple checkpoints, the active database subject to corruption, a system for, and method of, restoring the active database and a computer system containing the same. The system includes: (1) a checkpoint determination controller that determines which of the multiple checkpoints is a most recently completed checkpoint and copies the most recently completed checkpoint to the volatile memory to serve as an unrevised database for reconstructing the active database and (2) a revision application controller that retrieves selected ones of the revisions from the stable log and the tail and applies the revisions to the unrevised database thereby to restore the active database. In an advantageous embodiment, the applied revisions include log records at an operation level (lower level of abstration than transactions), and the revision application controller, using memory locks while restoring the active database, releases ones of the memory locks as a function of applying ones of the log records.
