Abstract: A method for secure restoration of data selected based on user-specified search criteria includes maintaining one or more backup versions of a plurality of storage objects and initiating the generation of a plurality of database entries, wherein each database entry corresponds to a backup version of a storage object and includes an encoding of a security descriptor associated with the storage object. The method may further include, in response to a backup version search request from a user, using contents of the search request and encodings of security descriptors stored in the plurality of database entries to identify one or more backup versions of a particular storage object that the user is authorized to access.

Abstract: A system for using recent activity information to select backup versions of storage objects for restoration comprises a processor and memory coupled to the processor, where the memory stores program instructions computer-executable by the processor to implement a backup manager. The backup manager is configured to maintain one or more backup versions of a plurality of storage objects and a plurality of access history records, where each access history record is associated with a particular backup version. Each access history record includes information indicative of an access to the corresponding storage object by a user. The backup manager may be configured to select a particular backup version as a restoration candidate using at least the contents of the access history record associated with the backup version.

Abstract: A bridge of a twin-T type may have been proposed before but not in the form and function of this DIGITAL RF BRIDGE. In the DETAILED DESCRIPTION and MATHEMATICS writings of this application I describe the DIGITAL RF BRIDGE and it's process as being unique. The computer used here will be of ordinary origin but equipped with the special software. The printer is common and standard The signal generator is common, same as used regularly in bridge measurement processes. The null detector will normally be constructed as a part of the main bridge unit, well shielded and tunable. The device for measuring capacity values of C1 and C2 will normally be constructed as part of the main bridge unit and will work with the computer software to derive capacity in picofarads The Digital RF Bridge is dependent upon the computer and it's software to execute it's functions and, likewise, the computer process is dependent upon the functions of the Bridge unit. In the absence of either one, the process cannot exist.
