  • Patent number: 10637684
    Abstract: The invention provides a mesh network bridging device adapted to allow a resource restricted device to pass and/or receive signals from a mesh network. The mesh network bridging device is operable over both a first communication channel, so as to communicate with the resource restricted device, and a second communication channel, so as to communicate with the mesh network. The mesh network bridging device is adapted to switch between a first and second mode of operation, associated with the first and second communication channel respectively, so as to alternately communicate with the resource restricted device and the mesh network bridging device. The mesh network bridging device may thereby act as a bridge between the resource restricted device and the mesh network bridging device.

  • Patent number: 10393778
    Abstract: The invention relates to a disaggregation apparatus (1) for identifying an electrical consumer in an electrical network (2). An electrical signature providing unit (7) provides electrical signatures of the electrical consumers (4, 5, 6), and an electrical parameter determining unit (8) determines an overall electrical parameter of the electrical network (2). An identification unit (9) identifies an electrical consumer depending on the determined overall electrical parameter and a correlation of the electrical signatures. Since the identification unit identifies an electrical consumer depending on the determined overall electrical parameter and a correlation of the electrical signatures, the identification of an electrical consumer does not depend on the detection of an event only. This makes the identification more robust, especially less prone to errors caused by missed events, thereby improving the reliability of identifying an electrical consumer in the electrical network.

  • Patent number: 9979559
    Abstract: The disclosure relates to an application server which provides a user of a mobile device with a location based service controlling functionality of an environment external to the mobile device, where the control of the functionality is conditional on an estimated location of the mobile device as estimated by a positioning algorithm. A feedback module is configured to infer a quality of the estimation from the behavior of the user, based on a manner in which the user interacts or attempts to interact with the functionality of the location based service. The feedback module then sends feedback of the inferred quality to the positioning algorithm.
