    摘要： Disclosed is a SmartDust system for contactless digital controlled serialized analog processing of analog values received from an object. The SmartDust system includes a hub unit and at least one electronic circuitry capacitive coupled to the hub unit. The hub unit includes an oscillator for generating a frequency, and a first electrode connected to the oscillator to emit the frequency as an alternating electric field. The electronic circuitry stores and performs switching instructions and the digital logic operations. The electronic circuitry receives analog values and generate sampled and processed analog values. The electronic circuitry provides the processed values to external components. The hub unit includes a controller for providing the switching instructions and the digital logic operations to the electronic circuitry, and a modulator for modulating the alternating electric field with the switching instructions and the digital logic operations.

    摘要： A Reconfigurable Intelligent Surface (RIS)/Light Fidelity (LiFi) rack communication system includes a rack that includes a computing device, a LiFi device that transmits first light-modulated data, and a RIS system. The RIS system includes a RIS device that directs the first light-modulated data transmitted by the LiFi Device at the computing device, and a RIS control subsystem that is coupled to the at least one RIS device. The RIS control subsystem determines a first signal integrity of the first light-modulated data received by the computing device via the RIS device when the RIS device includes a first configuration, and reconfigures the RIS device with a second configuration such that the first light-modulated data received by the computing device via the RIS device includes a second signal integrity that is greater than the first signal integrity.

    摘要： A method (100) for managing Optical Wireless Communication (OWC) in a User Equipment (UE) is disclosed, the UE being configured for Radio Frequency (RF) communication with a network and comprising at least two OWC receivers. The method comprises monitoring a captured luminous flux intensity at the OWC receivers (1 10) and, if a captured luminous flux intensity at at least one of the OWC receivers is above a viability threshold (120), selecting the OWC receiver having the highest captured luminous flux intensity (130) and extracting client data from an optical signal received on the selected OWC receiver (140). Also disclosed are a UE (300, 700) configured for RF communication with a network and for OWC, the UE comprising at least two OWC receivers, and a controller (500, 600) for managing OWC in a UE.

    摘要： The invention relates to a method for directing communication traffic to and from a communication unit within an application control system, wherein the application control system comprises a plurality of application control components and the application control components are capable of transmitting messages to the communication unit using light waves. By determining position information of the application control components within the application control system and of a first communication unit within the application control system, an area of interest for the first communication unit is computed based on at least the first position information. A first subgroup of one or more application control components from the plurality of application control components located within the area of interest of the first communication unit is identified and data paths through the application control system are programmed to communicate with the communication unit using the identified subgroup of application control components.
