Patent number: 11924173Abstract: An edge node has a central processing operable to gather sensor node data via a sensor and store at least part of the sensor node data locally in a public region of a persistent storage. The edge node backs up duplicate portions of the sensor node data to public storage regions of peer-edge nodes. The edge node receives private data from a host that is coupled to the edge computing node and the peer edge nodes, and stores the private data in a private region of the persistent storage. The private region is protected from the peer edge nodes using distributed key management.Type: GrantFiled: April 13, 2021Date of Patent: March 5, 2024Assignee: Seagate Technology LLCInventors: Mehmet Fatih Erden, Walter R.

Patent number: 11503381Abstract: A distributed video management system for distributed processing and storage of captured video data. The distributed video management system includes a plurality of video cameras that each communicate video data to a respective one of a plurality of camera nodes. Each camera node includes a camera manager for processing video data received at the camera node. The camera nodes are in operative communication with storage resources for storage of the video data in a logical storage volume for the system according to a storage policy. The storage policy may include multiple phases with data pruning for controlled reduction of the size of video data stored on disk. The distributed system may also generate and maintain a ledger or database regarding the captured and stored video data to correlate the video data with system metadata and/or analytical metadata regarding the video data.Type: GrantFiled: June 29, 2020Date of Patent: November 15, 2022Assignee: SEAGATE TECHNOLOGY LLCInventors: Greg D. Larrew, Margot A. LaPanse, Michael Habinsky, Michael E. Baum

Patent number: 11463739Abstract: A distributed video management system for video surveillance that allows for monitoring a camera allocation parameter and dynamic reallocation of video cameras to available camera nodes in response to detecting a change in the allocation parameter. As such, the system may provide for load balancing of the processing of video data from the video cameras with reference to the allocation parameter. The change in allocation parameter may be due to a number of potential contexts, including a change in availability of camera nodes, a change in the nature of the video data captured, a change in computational load, or other change that results in a change in allocation parameter. The allocation parameter may be continually monitored to allocate video cameras to camera nodes in the system for enhanced system performance in view of potentially changing conditions.Type: GrantFiled: June 29, 2020Date of Patent: October 4, 2022Assignee: SEAGATE TECHNOLOGY LLCInventors: Greg D. Larrew, Margot A. LaPanse, Michael Habinsky, Michael E. Baum

Patent number: 11343544Abstract: A distributed video management system that allows for monitoring a camera allocation parameter and dynamic reallocation of video cameras to available camera nodes in response to detecting a change in the allocation parameter including selectively dropping at least one camera from the system based on a priority of the camera. The change in allocation parameter may be due to a number of potential contexts including a change in availability of camera nodes, a change in the nature of the video data captured, a change in computational load, or other change that results in a change in allocation parameter. The disconnection or “dropping” of a camera may be temporary in response to an increase in computational load on the system. The use of priority values of the cameras may allow for sufficient camera coverage to be provided by the system while maintaining processing of video data from higher priority cameras.Type: GrantFiled: June 29, 2020Date of Patent: May 24, 2022Assignee: SEAGATE TECHNOLOGY LLCInventors: Greg D.

Publication number: 20210409792Abstract: Video analysis in a distributed video management system in which video data from a given camera is sent to at least two distributed camera nodes for simultaneous processing of video data by the distributed camera nodes. In some examples, the respective camera nodes may execute video analysis modules that each apply a different video analysis module to the video data. Video data may, by default, be provided to a first camera node. In turn, upon detection of a trigger, video data may be provided to a second camera node. The trigger may be periodic or, for example, in response to metadata generated by the first video analysis module of the first camera node. In turn, versatile and robust video analysis may be performed by the distributed video management system.Type: ApplicationFiled: June 29, 2020Publication date: December 30, 2021Inventors: Greg D.

Publication number: 20210409817Abstract: A distributed video management system for video surveillance that allows for adaptive transport mechanisms and/or real-time transport mechanisms for delivery of data to a client. The adaptive transport mechanism may include processing video data at distributed camera nodes for delivery to a client at least in part based on a characteristic of the request. In certain contexts, a low-latency real-time transport mechanism may be used to deliver video data to the client. In this regard, the real-time transport mechanism may facilitate decoding of the video data at the client using a standard web browser without requiring extensions, plug-ins, or other software to be installed for use with the native functionality of the browser.Type: ApplicationFiled: June 29, 2020Publication date: December 30, 2021Inventors: Greg D.

Patent number: 10628045Abstract: Apparatus and method for managing data in a hybrid data storage device. In some embodiments, the hybrid data storage device has a hard disc drive (HDD) controller circuit coupled to non-volatile rotatable storage media and a solid state drive (SSD) controller circuit coupled to non-volatile solid state memory. A local memory stores a map structure which identifies logical addresses of current version data sets stored in the solid state memory. A top level controller circuit operates responsive to the map structure to direct a selected host data transfer access command to the HDD or SSD controller circuit. The map structure may be arranged as a plurality of discrete logical address sequences, where a gap is provided between each adjacent pair of the discrete logical address sequences in the map structure.Type: GrantFiled: June 23, 2016Date of Patent: April 21, 2020Assignee: Seagate Technology LLCInventors: John E.

Patent number: 10459658Abstract: Apparatus and method for managing data in a hybrid data storage device. In some embodiments, a hybrid device has a hard disc drive (HDD) controller circuit coupled to non-volatile rotatable storage media and a solid state drive (SSD) controller circuit coupled to non-volatile solid state memory. A top level controller circuit directs a first portion of the received access commands to the HDD controller circuit and a second portion of the received access commands to the SSD controller circuit. The top level controller circuit performs an embedded queuing operation to forward internally generated data cleaning commands to an HDD command queue to write data previously transferred from the host device to the solid state memory to the rotatable storage media concurrently while least one of the first portion of the access commands is pending in the HDD command queue.Type: GrantFiled: June 23, 2016Date of Patent: October 29, 2019Assignee: Seagate Technology LLCInventors: Stanton M.
