Identifying and retrieving video metadata with perceptual frame hashing
Shoppable video enables a viewer to identify and buy items appearing in a video. To retrieve information about the items in a frame of the video, the playback device generates a perceptual hash of that frame and uses that hash to query a first database storing perceptual hashes of different version of the video.

Lightweight data reconstruction based on backup data
A information management system allows a user to search through a secondary copy of data, such as a back up, archive, or snapshot without first retrieving the secondary copy of data.

Multi-tiered backup indexing
Certain embodiments disclosed herein reduce or eliminate a communication bottleneck at the storage manager by reducing communication with the storage manager while maintaining functionality of an information management system. In some implementations, a client obtains information for enabling a secondary storage job (e.g., a backup or restore) from a storage manager and stores the information (which may be referred to as job metadata) in a local cache. The client may then reuse the job metadata for multiple storage jobs reducing the frequency of communication with the storage manager. When a configuration of the information management system changes, or the availability of resources changes, the storage manager can push updates to the job metadata to the clients. Further, a client can periodically request updated job metadata from the storage manager ensuring that the client does not rely on out-of-date job metadata. |

Occurrence of a RAID double failure in a slice of a RAID protection group (failed slice) renders data stored in the back-end tracks of the failed slice vulnerable to loss. When a RAID double failure is detected, a new slice is added to the RAID protection group. Front-end tracks that map to the good back-end tracks of the failed slice are moved from the back-end tracks of the failed slice to the back-end tracks of the newly added slice. Any front-end tracks that mapped to the bad back-end tracks of the failed slice are made to be write pending and written to corresponding back-end tracks of the newly added slice. Front-end tracks that map to the bad back-end tracks may be made to be write-pending in connection with a host write operation, by reading the front-end tracks from a local backup, or from a remote backup location. |

Component machining apparatus
A component machining apparatus includes a measurement result acquiring unit and a machining data generator. The measurement result acquiring unit is configured to acquire a measurement result obtained by a measurer configured to measure a three-dimensional shape of a manufactured component among components of a structure. The manufactured component is manufactured earlier than a component of interest. The machining data generator is configured to generate machining data of the component of interest based on the measurement result of the manufactured component that has been acquired by the measurement result acquiring unit. |

Apparatus and methods for high-speed and long depth range imaging using optical coherence tomography
Exemplary apparatus can be provided which can include a laser arrangement that is configured to provide a laser radiation, and including an optical cavity. The optical cavity can include a dispersive optical waveguide first arrangement having first and second sides, and which is configured to (i) receive at least one first electro-magnetic radiation at the first side so as to provide at least one second electro-magnetic radiation, and (ii) to receive at least one third electro-magnetic radiation at the second side so as to provide at least one fourth electro-magnetic radiation. The first and second sides are different from one another, and the second and third radiations are related to one another. The optical cavity can also include an active optical modulator second arrangement which can be configured to receive and modulate the fourth radiation so as to provide the first electro-magnetic radiation to the first arrangement. The laser radiation can be associated with at least one of the first, second, third or fourth radiations. |

Chemical agent delivery receptacle with reusable digital control cartridge
A digitally controlled hand-tossable explosive delivery receptacle comprises a ruggedized reusable compartment enclosing a digital circuit and a disposable cartridge holding one or more explosive chemical agents and a primer. The disposable cartridge is configured to be mounted to the ruggedized reusable cartridge, and a high-strength bulkhead incorporated into the reusable or disposable compartment that separates the digital circuit from the chemical agents. The reusable compartment is sufficiently ruggedized to withstand the ignition of the primer and the detonation of the chemical agents to be reused with one or more additional disposable cartridges. In one implementation, the delivery receptacle uses a commercial airbag initiator as the primer, which is arranged in relation to the one or more chemical agents so that when the initiator is activated, it generates a pressure wave that expels the one or more chemical agents from the grenade. |
