  • Publication number: 20240242193
    Abstract: The present disclosure utilizes excess processing capacity of a point of sale (POS) system by dynamically managing assigned tasks based on an expected activity of an individual. A resource management system can use image data and a trained neural network to analyzes aspects of an appearance or a behavior of the individual as captured in the image data to quantify a likelihood of the individual participating in a checkout procedure. The resource management system can dynamically allocate resources across different POS systems in anticipation of expected activity. This allows for the efficient use of the POS systems' resources while maintaining good system performance and a positive experience.

  • Publication number: 20240205511
    Abstract: Methods and apparatus for providing delivery of content to client devices of a network via both multicast and unicast mechanisms. In one embodiment, a system for use in a managed content delivery network is described to bridge multicast to unicast, so that the total network bandwidth consumption is significantly lower than a corresponding unicast-only delivery solution, yet which still provides improved quality of service and user viewing experience as compared to a multicast-only delivery solution. In addition, various exemplary aspects of the present disclosure are readily adapted for real-time multicast to unicast streaming of audio and data to, among other things, minimize network bandwidth usage, while maintaining the guaranteed delivery of unicast streams with little or no modification to the existing client device logic.
