  • Patent number: 11921827
    Abstract: Disclosed is a system and method for the monitoring and authorization of an optimization device in a network. In exemplary embodiments, an optimization device transmits an authorization request message to a portal to receive authorization to operate. The portal transmits an authorization response message to the optimization device with capability parameters for operation of the device, including at least one expiration parameter for the authorization. The optimization device sends updated authorization request messages to the portal with its device usage information, such that the portal can dynamically monitor the optimization device and continue to authorize its operation.

  • Patent number: 11919313
    Abstract: A print device may include a refill interface, a processor, and a computer readable medium. The refill interface may have an electrical interface for transmission and reception of signals between the print device and a refill container. And the computer-readable medium may have instructions stored thereon that when executed by the processor are to cause the processor to fetch signals, via the electrical interface of the refill interface, from the refill container indicative of a licensed print functionality of the print device. The instructions may also be to enable the licensed print functionality on the print device responsive to the fetched signals and to maintain the licensed print functionality enabled subsequent to detachment of the refill container.

  • Patent number: 11924106
    Abstract: A system for facilitating sender-side granular congestion control is provided. During operation, the first and second processes of an application can run on sender and receiver nodes, respectively. A first buffer on the sender node can be allocated to the first process. For the first process, the system can then identify a second buffer at a last-hop switch of the receiver node. The system can determine, based on in-flight packets, the utilization of the second buffer. The system can also determine a fraction of available space in the second buffer for packets from the first buffer based on the utilization. Subsequently, the system can determine whether the fraction of the available space can accommodate the next packet from the first buffer. If the fraction of the available space can accommodate the next packet, the system can allow the first process to send the next packet to the second process.

    Abstract: Examples of electronic devices are described herein. In some examples, an electronic device includes a camera to capture a composite image comprising multiple images of a location. In some examples, the electronic device includes a processor to crop a portion of the composite image based on a field-of-view of the camera. In some examples, the processor is to determine whether a neural network identifies the cropped portion. In some examples, the processor is to generate a unique identifier (ID) for the cropped portion in response to the cropped portion being unidentified by the neural network. In some examples, the processor is to associate the unique ID of the cropped portion with the location.
