  • Publication number: 20240344786
    Abstract: A system for determining a cleaning schedule for an asset is provided. In some aspects, the system can include a plurality of sensors arranged to monitor an asset and a computing system including at least one data processor and memory storing instructions, which when executed by the at least on data processor causes the at least one data processor to perform operations. In some aspects, the operations performed by the processor can include receiving, from the plurality of sensors, the data characterizing the operational efficiency of the asset, determining an operational efficiency of the asset determining an operational efficiency threshold characterizing an undesirable operating efficiency, determining, using an optimization algorithm, a cleaning schedule for the asset based on the operational efficiency of the asset and the operational efficiency threshold and providing the cleaning schedule.

  • Patent number: 9924522
    Abstract: A method for selecting the state of a reconfigurable antenna installed at either the receiver or transmitter of a communication system is provided. The proposed method uses online learning algorithm based on the theory of multi-armed bandit to perform antenna state selection. The selection technique utilizes the Post-Processing Signal-to-Noise Ratio (PPSNR) as a reward metric and maximizes the long-term average reward over time. The performance of the learning based selection technique is empirically evaluated using wireless channel data. The data is collected in an indoor environment using a 2×2 MIMO OFDM system employing highly directional metamaterial Reconfigurable Leaky Wave Antennas. The learning based selection technique shows performance improvements in terms of average PPSNR and regret over conventional heuristic policies.

  • Patent number: 9236955
    Abstract: By using reconfigurable antenna based pattern diversity, an optimal channel can be realized in order to maximize the distance between two subspaces, thereby increasing sum-rate. The inventors show the benefits of pattern reconfigurability using real-world channels, measured in a MIMO-OFDM interference network. The results are quantified with two different reconfigurable antenna architectures. An additional 47% gain in choral distance and 45% gain in sum capacity were achieved by exploiting pattern diversity with IA. Due to optimal channel selection, the performance of IA can also be improved in a low SNR regime.
