Global de-duplication of virtual disks in a storage platform
In order to avoid writing duplicates of blocks of data into a storage platform, any virtual disk within the storage platform may have a de-duplication feature enabled. Or, all virtual disks have this feature enabled. For virtual disks with de-duplication enabled, a unique message digest is calculated for every block of data written to that virtual disk. Upon a write, these message digests are consulted in order to determine if a particular block of data has already been written, if so, it is not written again, and if not, it is written. All de-duplication virtual disks are written to a single system virtual disk within the storage platform. De-duplication occurs over the entire storage platform and over all its virtual disks because all message digests are consulted before a write is performed for any virtual disk. A read for a de-duplication virtual desk reads from the system virtual disk. |

Adjustable access energy and access latency memory system and devices
Same sized blocks of data corresponding to a single read/write command are stored in the same memory array of a memory device, but using different formats. A first one of these formats spreads the data in the block across a larger number of memory subarrays (a.k.a., memory array tiles—MATs) than a second format. In this manner, the data blocks stored in the first format can be accessed with lower latency than the blocks stored in the second format because more data can be read from the array simultaneously. In addition, since the data stored in the second format is stored in fewer subarrays, it takes less energy to read a block stored in the second format. Thus, a system may elect, on a data block by data block basis, whether to conserve power or improve speed. |

Multiscale deformation measurements leveraging tailorable and multispectral speckle patterns
Remote measurements using images are particularly useful in structural health monitoring cases in which the installation of contact sensors is difficult. Some limitations, though, associated with photogrammetry-type optical metrology involve the application of speckle patterns, which become even more important with variable working distance or when the required resolution and sensitivity are not a priori known. In this context, multispectral sensing combined with tailored speckle patterns can circumvent some of the challenges of acquiring data at different working distances. The present invention uses multispectral imaging combined controlled generation of speckle patterns to demonstrate an approach for remote sensing related to deformation measurements at the structural level. To demonstrate this approach, two speckle patterns were designed for measurements at specified working distances. The results show that the spectral specific reflectivity of the speckle patterns allow for spatial overlay without affecting imaging within either spectral range considered, which results in the extraction of multiscale deformation measurements. |

Morris 80 plastic tour bolt
When combined with a metal point, this ten inch plastic pistol crossbow bolt is designed to extend past the barrel of a pistol crossbow so it can be used for recreational shooting, competition shooting, small game hunting, pistol crossbow fishing and pistol crossbow scuba fishing. The main fault of the standard pistol crossbow bolt is they are less than seven inches in length and do not extend past the end of a pistol crossbow barrel. Therefore, their use is limited to target points and recreational shooting only. Other faults of the standard short pistol crossbow bolts are their high travel speed. They are very difficult to be viewed in flight, causing most bolts to be lost after one use. Also, their irretrievability from any commonly used target. Therefore, they cannot be found and scored in any type of shooting competition. This ten inch bolt is a solid one piece unit made of a strong but, light weight plastic compound. It has a NOCK to securely hold the bow string in place. Most bolts do not have a nock. it has two FLAT WINGS for elevation stabilizing which creates an accurate and stable bolt flight. No other bolt has this type of flat wings. These features allow this bolt to be easily viewed in flight. This also allows this bolt to be used for competition shooting because these bolts can be easily located, scored and then retrieved from any type competition target. The shaft has a THREADED TIP to accept almost any type metal point. |
