20090124207 | Protocol Reference Model, Security and Inter-Operability in a Cognitive Communications System - Various cognitive communications system architectures and their corresponding Protocol Reference Models (PRMs) are disclosed. Such PRMs incorporate a Cognitive Plane in addition to conventional Data and Management Planes. The additional Cognitive Plane functionality may include, for example, spectrum sensing, spectrum management, geolocation, and security functions. The Cognitive Plane may further include a Policy Engine and a Learning and Reasoning Module. In some embodiments, Management Plane functions may be effectively combined to form a database of primitives (and their respective values) called a Management Information Base (MIB). In addition, techniques are provided by which various components of cognitive and non-cognitive, as well as mesh-enabled and non-mesh-enabled nodes in a network, inter-operate with each other. The architectures allow a Spectrum Manager (or Signal Space Manager) to combine information from various network layers (e.g., PHY/MAC Layers, Spectrum Sensing Function, Geolocation Function, and/or Security Sublayers), and to make informed decisions on spectrum utilization. | 05-14-2009 |
20100302086 | COMPRESSIVE SENSOR ARRAY SYSTEM AND METHOD - A compressive sensor array (CSA) system and method uses compressive sampling techniques to acquire sensor data from an array of sensors without independently sampling each of the sensor signals. In general, the CSA system and method uses the compressive sampling techniques to combine the analog sensor signals from the array of sensors into a composite sensor signal and to sample the composite sensor signal at a sub-Nyquist sampling rate. At least one embodiment of the CSA system and method allows a single analog-to-digital converter (ADC) and single RF demodulation chain to be used for an arbitrary number of sensors, thereby providing scalability and eliminating redundant data acquisition hardware. By reducing the number of samples, the CSA system and method also facilitates the processing, storage and transmission of the sensor data. | 12-02-2010 |

20130024640 | Virtual Logical Volume for Overflow Storage of Special Data Sets - Method and system embodiments for facilitating overflow storage of special data sets that reside on a single logical volume are provided. A virtual logical volume is created from unallocated memory units across a plurality of logical volumes in a volume group. The virtual logical volume appears the same as any one of the logical volumes in the volume group to an external client. Upon receipt of a special data set that must reside in a single logical volume, an attempt is first made to allocate the special data set to one of the logical volumes in the volume group. If that allocation attempt fails, the special data set is allocated to the virtual logical volume. The virtual logical volume may be created only upon the failure to allocate the special data set to one of the logical volumes, and may be destroyed if sufficient space in one of the logical volumes is freed up to transfer the special data set. Creation of the virtual logical volume may be reserved for only critical special data sets whose failure would result in a storage system outage. | 01-24-2013 |
20130173542 | REPLICATION OF DATA SETS - An approach that allows for replicating data sets that have different attributes. A logical copy operation may not be possible from a source data set to a target data set due to differences between their respective attributes. The source data set may have obsolete attributes that prevent a logical copy to a target data set with supported attributes. The presented solution may involve allocating an intermediate data set with the same attributes as the source data set. The intermediate data set may be allocated with the same obsolete attributes as the source data set. The approach may also involve executing a logical copy operation from the source data set to the intermediate data set. A standard copy operation that reformats the data may be executed on the intermediate data set to the target data set. | 07-04-2013 |
