Patent number: 12118840Abstract: Systems and methods for processing telematics data streams for event detection are provided. The methods involve operating at least one processor to: receive a telematics data stream; define a plurality of sliding windows for the telematics data stream, each sliding window containing a portion of the telematics data stream, each sliding window overlapping with one or more neighboring sliding windows, each sliding window including: a logical window; a first buffer preceding the logical window; and a second buffer following the logical window; the logical window being adjacent with one or more neighboring logical windows of the one or more neighboring sliding windows without overlapping the one or more neighboring logical windows; identify a vehicle event based on the portion of the telematics data stream contained within one of the sliding windows; and store an indication of the vehicle event.Type: GrantFiled: July 10, 2023Date of Patent: October 15, 2024Assignee: Geotab Inc.Inventors: Mengyang Liu, Xiao Ma, Nianlong Yu, Wenyang Liu

Patent number: 12067243Abstract: Techniques for processing read/write requests involve determining an average response time for read/write requests to a storage device within a predetermined time period, and comparing the average response time with at least one predetermined threshold. Such techniques further involve adjusting a read/write request upper limit of the storage device based on the comparison between the average response time and the at least one predetermined threshold. Here, the read/write request upper limit indicates the maximum number of read/write requests in a read/write request queue for the storage device. In this way, the read/write request upper limit of a storage device may be dynamically adjusted based on a current response time of the storage device for processing read/write requests, and slow read/write processing caused by the accumulation of read/write requests at one storage device can be avoided.Type: GrantFiled: November 3, 2022Date of Patent: August 20, 2024Assignee: Dell Products L.P.Inventors: Wenyang Liu, Ying Tian, Dapeng Chi, Yang Song, Wen Jiang

Patent number: 11995358Abstract: Techniques manage extents in a storage system having storage devices supporting a redundant storage strategy. A reserved area of the storage system is generated based on a set of first-type reserved extents respectively located in the storage devices, and the set of first-type reserved extents supports a reconstruction operation for a failed storage device when the failed storage device appears in the storage devices. A data area is generated based on a set of data extents respectively located outside the reserved area in the storage devices, and the data area provides data storage for a user. Here, a reserved extent size of the set of first-type reserved extents is smaller than a data extent size of data extents in the data area of the set of data extents. The quantity of extents can be reduced, thereby reducing overhead of storage and computing resources involved by associated metadata.Type: GrantFiled: May 27, 2022Date of Patent: May 28, 2024Assignee: EMC IP Holding Company LLCInventors: Sheng Wang, Huan Chen, Dapeng Chi, Wenyang Liu, Ying Tian
