Abstract: A multi-dimensional database and indexes and operations on the multi-dimensional database are described which include video search applications or other similar sequence or structure searches. Traversal indexes utilize highly discriminative information about images and video sequences or about object shapes. Global and local signatures around keypoints are used for compact and robust retrieval and discriminative information content of images or video sequences of interest. For other objects or structures relevant signature of pattern or structure are used for traversal indexes. Traversal indexes are stored in leaf nodes along with distance measures and occurrence of similar images in the database. During a sequence query, correlation scores are calculated for single frame, for frame sequence, and video clips, or for other objects or structures.

Abstract: A computing system identifies multiple matching points between (i) query fingerprints representing a media stream being received by a client and (ii) reference fingerprints, each identified matching point defining a respective match between a query fingerprint timestamped with client time defined according to a clock of the client and a reference fingerprint timestamped with true time defined according to a timeline within a known media stream. Further, the computing system performs linear regression based on the timestamps of the matching points, to establish a mapping between true time and client time. The computing system then uses the mapping to determine a client-time point at which the client should perform a content revision or other action with respect to the media stream being received by the client. And the computing system causes the client to perform the content revision or other action at the determined client-time point.

Abstract: Some embodiments may be associated with a cloud-based computing environment. A computer processor of an orchestration layer platform may deploy and manage multi-tenant workloads (e.g., each being associated with a Virtual Machine (“VM”)) in the cloud-based computing environment. A Kubernetes control plane operator associated with the multi-tenant workloads may detect a trigger event (e.g., an actual VM state not matching a desired VM state) that results in a reconciliation request for a particular tenant workload. Responsive to the reconciliation request, serverless tenant execution code, representing reconciler logic compiled into a Web Assembly (“WASM”) module, may be spun up in a WASM sandbox to perform reconciliation for the particular tenant workload.

Abstract: A reconfigurable image processing pipeline includes an image signal processor (ISP), a control processor, and a local memory. ISP processes raw pixel data for a frame based on an image processing parameter and provides lines of processed pixel data to control processor via a first interface. For each region of interest (ROI) in the frame, ISP generates auto-exposure and auto-white balance (2A) statistics based on the lines for the ROI and writes them to the local memory via a second interface. Control processor reads 2A statistics from the local memory, determines the image processing parameter based on them, and provides the image processing parameter to ISP. ISP also generates an integer N bin histogram for control processor, which sums a portion of the N total bins and compares the summed bin count to a lighting transition threshold. The image processing parameter is further based on the comparison.

A dispatcher platform may determine that a first tenant actor is to be created for a first tenant in connection with a workload associated with a plurality of tenant identifiers. The first tenant may be, for example, associated with a first tenant identifier. The dispatch platform may then select a first thread for the first tenant actor from a pool of available threads and spin a first web assembly module such that execution of the first web assembly module is associated with a first web assembly browser sandbox. The dispatcher platform can then securely create the first tenant actor within the first web assembly browser sandbox to execute the workflow for the first tenant identifier. Similarly, a second web assembly browser sandbox may execute a second tenant actor for a second tenant identifier.

Abstract: Use of size-isolated microbubbles (SIMs) for sonoporation using a sonoporation system. The sonoporation system may include a SIM product administered in conjunction with an administered drug. Targeted ultrasound energy using an ultrasound device of the sonoporation system may result in sonoporation in response to cavitation of the SIM product in a targeted area of soft tissue. In turn, targeted delivery of the drug to the targeted area may occur. Results demonstrate improved outcomes using much reduced drug doses that allow for side effects and adverse reactions to be reduced or eliminated when used in conjunction with sonoporation as contemplated herein.
