  • Patent number: 9953199
    Abstract: Example implementations relate to using an auxiliary image to identify an image analysis mechanism associated with a main image. For example, a computing device may include a processor and an image capture device. The processor may capture with the image capture device a representation of a combined image. The combined image may include a main image and an auxiliary image. The processor may also identify the auxiliary image in the representation of the combined image and decode the identified auxiliary image via an auxiliary image decoding mechanism to determine image analysis mechanism identification information associated with the main image. The processor may further determine, based on the image analysis mechanism identification information, a main image analysis mechanism useable to determine an identifier associated with the main image. The auxiliary image decoding mechanism is different than the main image analysis mechanism.

  • Patent number: 9952796
    Abstract: Methods and systems for storing data in memory arrays are described. In one implementation, input bits are encoded into an intermediate binary array having multiple sub-arrays iteratively appended row-wise to the intermediate binary array. First sub-array is generated based on the input bits such that each row of the first sub-array has a number of 1's equal to a fraction of number of columns in the first sub-array, and based on a column balance coding such that the columns of the first sub-array have an equal number of 1's. At least one subsequent sub-array is generated based on a set of bits obtained from balancing termination indices for a previous sub-array and from diagonal bits of the intermediate binary array that are a part of the previous appended sub-array. The intermediate binary array is transformed to an encoded bit pattern. The encoded bit pattern is stored in the memory array.

  • Patent number: 9948525
    Abstract: Storage unit priority based on configuration information may be determined, for example, by a processor analyzing configuration information associated with the storage units to create a priority order associated with the storage units. The configuration information associated with each storage unit may be standardized for comparison to the configuration information associated with the other storage units. The processor may perform an action related to the storage units according to the priority order.

  • Publication number: 20180103181
    Abstract: Examples relate to providing synchronized look-up table loading. In some examples, a print job is processed using an initial look-up table in processor memory. In response to the processing of the print job reaching a buffer trigger row of a portion of the print job, look-up metadata is accessed to locate a next look-up table. At this stage, the next look-up table is dynamically loaded into the processor memory as the processor continues to process the print job, where the processing of the print job begins using the next look-up table after a target row of the portion of the print job is reached.

  • Publication number: 20180099496
    Abstract: Methods and apparatus for three-dimensional object representation are described. In an example, data representing a three-dimensional object is received, the data comprising an object property description associated with each of a plurality of locations within the object. Distinct object property descriptions are identified and a data object, which has a plurality of addresses, is populated with data indicative of the distinct object property descriptions, such that data indicative of each distinct object property description is represented at a different address. Data comprising a representation of the object is generated, the data comprising a data object address associated with each of a plurality of locations, wherein the data object address corresponds to the address of data indicative of the object property description for that location.

  • Patent number: 9940152
    Abstract: Described herein are techniques for configuring a volume shadow copy service (VSS) requester and/or VSS provider so that a snapshot may be taken of application data stored on a virtual volume (VVOL). The VSS requester may receive a request to take a snapshot of a VVOL, the VVOL identified by a VVOL identifier. The VSS provider associated with a storage array may determine whether the storage array supports taking the snapshot of the VVOL. The determination may be based on information derived from a mapping which maps respective VVOL identifiers to respective logical unit identifiers. If the VSS provider supports taking the snapshot of the VVOL, the VSS provider may take the snapshot of the VVOL.
