  • Patent number: 12511947
    Abstract: A management server system may obtain a request for image data from a computing device. The request may identify a subset of image data to be downloaded and/or streamed to the computing device. The management server system can provide an indication of a storage destination for the image data to a gateway device and initiate upload of the image data from the gateway device to the storage destination. The management server system may monitor the upload and, based on the monitoring, determine the upload is complete. The management server system can cause display of a user interface that includes a visualization of the image data for download of the image data from the storage destination to the computing device.

  • Patent number: 12368903
    Abstract: A video streaming system including a video cache system having a cache database and a video storage device, and including a video server configured to communicate with a gateway system configured to store multiple video streams, communicate with a cloud backup system configured to store video in a file system, and communicate with a cloud server to receive a stream request, the stream request indicating requested video that comprises multiple video segments. The video server is further configured to receive the stream request and determine a playlist that indicates where on the video cache system, the cloud backup system, and the gateway system the video segments that are needed to fulfill the stream request are stored, and to communicate needed video segments to the video cache system in preparation for providing streaming video to fulfill the stream request.

  • Publication number: 20240312808
    Abstract: An integrated die ejector for separating a die from a wafer, the die ejector includes an ejector mechanism that includes an ejector pin. There is an ejector base coupled to the ejector pin and configured to couple the integrated die ejector to a die attach ejector machine. There is a pepper pot at least partially surrounding the ejector mechanism and ejector base and a sleeve coupled thereto and positioned between the ejector mechanism and pepper pot. The sleeve and pepper pot define an upper and lower motion limit of the ejector base and retain the ejector mechanism within the pepper pot such that the integrated die ejector may be coupled to and decoupled from the die attach ejector machine as a single unit to reduce installation time.

  • Publication number: 20230260949
    Abstract: A semiconductor device includes a first semiconductor die having a top planar surface and a second semiconductor die having a bottom planar surface and a top planar surface. A protective layer including a bottom planar surface and a top planar surface is positioned between the first semiconductor die and the second semiconductor die. An adhesive layer having a top planar surface and a bottom planar surface is between the protective layer and the second semiconductor die. A periphery of the top planar surface of the first semiconductor die is covered by a periphery of the bottom planar surface of the protective layer after cutting a portion of the protective layer that extended past the periphery of the surface of the first semiconductor die. The protective layer reduces the occurrence of peeling of the second semiconductor die and first semiconductor die coupled to the protective layer.

  • Publication number: 20230046453
    Abstract: A one-piece clamp assembly for a window covering is disclosed. The window covering consists of a left side portion and right side portion connected to a moveable hinge portion. The left side portion comprises a plurality of rounded extrusions and at least one vertical rounded extrusion that securely mates into a hole or slot on the right side portion. The left side portion further comprises extruded walls that mate with single and double spikes found on the right side portion. The extruded portions and mating spikes provide for a secure connection of the clamp assembly to the window covering. A connecting slot is placed on either the left or ride side portion, enabling the clamp assembly to fasten to a head rail fastener of a window covering.

  • Patent number: 11050933
    Abstract: A method for determining a location of a target positioned behind a tow vehicle is provided. The method includes receiving images from a camera positioned on a back portion of the tow vehicle. The images include the target. The method includes applying one or more filter banks to the images. The method also includes determining a region of interest within each image based on the applied filter banks. The region of interest includes the target. The method also includes identifying the target within the region of interest and determining a target location of the target including a location in a real-world coordinate system. The method also includes transmitting instructions to a drive system supported by the vehicle. The instructions cause the tow vehicle to autonomously maneuver towards the location in the real-world coordinate system.
