  • Publication number: 20220027341
    Abstract: A computer implemented method of providing a localised consensus mechanism for a distributed ledger comprising a plurality of nodes. The method comprises, in one or more nodes of the plurality of nodes, receiving, from a sensor associated with the node of the plurality of nodes, a signal indicative of a physical property sensed by the sensor and generating, based on the received signal, an initial transaction record. The method further comprises forming a localised consensus of a transaction record to be added to the distributed ledger based on the initial transaction records generated by the one or more nodes of the plurality of nodes, generating said transaction record using the localised consensus and adding the transaction record to the distributed ledger.

  • Publication number: 20200407879
    Abstract: A controllable collecting apparatus for a spinning track of a centrifugal electrostatic spinning device. The spinning track controllable collecting apparatus includes a base part and a controller, where a collecting side of the base part is provided with a plurality of electrodes distributed in an array mode, a plurality of control interfaces of the controller are respectively used for controlling the corresponding electrodes to be electrified when started, and the controller can control each control interface to be started according to a predetermined sequence. The arrayed electrodes are arranged on the collecting side and are controlled to be switched on or off by the controller according to the predetermined sequence so that spun filaments are attached to the spinning track controllable collecting apparatus according to a predetermined track to effectively locate a spinning attachment track. That is, better filaments can be spun to achieve a better spinning effect.

  • Patent number: 10748361
    Abstract: A method of remotely controlling access to a resource. The method comprising receiving a plurality of signals from a remote key wherein the remote key only transmits the plurality of signals if the remote key is moving. The method further comprises estimating a first and a second position of the remote key based on a characteristic of a first and a second signal respectively, and unlocking access to the resource if the remote key is moving towards the resource based on the first and the second estimated position.
