  • Patent number: 11103760
    Abstract: We generally describe an audio-based line fault detection system for a sports game. The audio-based line fault detection system comprises one or more audio sensors (102) for sensing an audio signal generated by a sports gaming device bouncing off a sports field. The sports field comprises surface modifications applied to a line and/or an area adjacent to the line on the sports field such that the generated audio signal is dependent on whether or not the sports gaming device bounces off the sports field where the surface modifications are applied. The detection system is configured to generate a sound profile from the audio signal sensed by the one or more audio sensors (102). The detection system is further configured to identify a bounce type based on the sound profile, wherein the bounce type is defined by whether or not the sports gaming device has bounced off the sports field where the surface modifications are applied.

  • Publication number: 20180159940
    Abstract: A method for managing a content request from a Communication Device, CD, is presented. The method is performed by a cache server and comprises: receiving a request for a content from a Communication Device, CD, the request further comprising a user session token; and providing the requested content to the CD when the user session token is cached on the cache server and when the content is cached on the cache server. A corresponding cache server, computer program and computer program product are also presented.

  • Publication number: 20150147956
    Abstract: The present invention relates to a control means for a channel connectable to a central flow system configured to create an underpressure or overpressure in the channel. The control means is configured to increase or decrease the flow resistance in the channel. The control means is further configured to reduce flow resistance when the flow in said channel falls below a preset flow and to increase the flow resistance when the flow in said passage exceeds the said preset flow.
