Abstract: The invention relates to a method of determining wear of a data storage medium actively by performing a read operation on the data storage medium and detecting a read signal, comparing the read signal to at least one wear threshold; and determining a wear level of an area of the data storage medium based on the comparison. The wear threshold is lower than a detection threshold, wherein the detection of the read signal above the detection threshold indicates the presence of stored data.

Abstract: An apparatus for determining data signatures in a dynamic distributed device network may include a processor. The processor may be configured to receive a first query and generate a local partial closure of the data identified by the first query. The processor may be further configured to synthesize a data signature of the local partial closure. In this regard, the data signature may be an irreducible polynomial expression and the data signature may be orthogonal to remote data signatures generated from remote partial closures. Further, the processor may be configured to store the data signature in an information store within a dynamic distributed device network. Associated methods and computer program products may also be provided.

Abstract: An apparatus for determining a master module in a dynamic distributed device environment may include a processor. The processor may be configured to calculate a connectivity stability factor for a module. The module may be included on a device configured to be connected to a distributed device network. The distributed device network may be defined as a network where devices leave or enter the network at any time, such as a smart space. The processor of the apparatus may also be configured to weigh the connectivity stability factor of the module against neighboring connectivity stability factors associated with neighboring modules, and assign a role of master module to the module based on a determination that the connectivity stability factor of the module describes a more stable module than the connectivity stability factors of the neighboring modules. Associated methods and computer program products may also be provided.

Abstract: An apparatus for distributed information management may include a processor. The processor may be configured to select one or more network domain features and one or more information domain features. In this regard, the network domain features may be based on the connectivity of a network, and the information domain features may be based on meta-data associated with information stored within the network. The processor may also be configured to determine a network domain covariance based on the one or more network domain features and determine an information domain covariance based on the one or more information domain features. Further, the processor may be configured to combine the network domain covariance and the information domain covariance to determine a path update. Associated methods and computer program products may also be provided.
