    摘要： This application is directed to device synchronization and alignment in extended reality. Two electronic devices create two maps of a scene according to two distinct coordinate systems. A first electronic device determines a device pose of a second electronic device in a first coordinate system of the first electronic device. The device pose is used to determine a transformation relationship between the two coordinate systems. The first electronic device obtains a second object pose that is measured in a second coordinate system of the second electronic device and used to render an object in a second map of the second electronic device. The second object pose is converted to a first object pose in the first coordinate system based on the transformation relationship. The object is rendered concurrently in the first and second maps of the first and second electronic devices based on the first and second object poses, respectively.

    摘要： An object is to provide a terminal device, a communication method, and a communication system which are capable of acquiring accurate optical ID information regardless of the position of the terminal device and the light receiving angle.
    The terminal device, the communication method, and the communication system according to the present invention each sets a threshold value for the illuminance of a received optical signal by using a moving average method, a weighted moving average method, or an exponential moving average, so that the optical signal can be binarized with a threshold value according to a change in the position of the terminal device, the light receiving angle, or the like. Information from other sensors may be used to set the threshold value.

    摘要： An optical wireless communications, OWC, network (100) comprises a plurality of access points (120) for communicating with a plurality of endpoint devices (110) via modulated light. A control system (13) receives a report indicating a timeslot during which a first one of the access points (120a) detected an event indicative of interference and transmits an indication of the timeslot to at least one other access point (120b). The other access point (120b) provides to the control system (13) identifiers of any registered endpoint devices which used or are using that timeslot. If the control system (13) receives an identifier of a single endpoint device from the other access point (120b), it determines that endpoint device as a cause of the interference experienced at the first access point (120a). If the control system (13) receives identifiers of plural endpoint devices from other access points (120), it causes endpoint devices in the OWC network (100) to advertise their presence.

    摘要： There is provided a method including receiving an incoming ID at a first wearable heads-up display (WHUD), which incoming ID is associated with a communicant device. The method also includes sending match data from the first WHUD to a match engine. The match data includes a first WHUD ID and the incoming ID. Moreover, the method includes receiving a match indicator at the first WHUD from the match engine. The match indicator is to indicate a match event between the first WHUD and the communicant device based on the match data. Furthermore, the method includes effecting communication between the first WHUD and the communicant device comprising at least one of sending a message from the first WHUD to the communicant device and receiving at the first WHUD a corresponding message from the communicant device. The first WHUD, and a method of operating the match engine are also described.

    摘要： A control device is provided in an access point including an input/output interface connected to a communication bus using a communication protocol, a transmitting stage for converting a first signal from the input/output interface into a transmitted light signal, and a receiving stage for converting a received light signal into a second signal passed on to the input/output interface. This control device is arranged either to disable the receiving stage when the input/output interface receives a first signal from the communication bus, and to enable the receiving stage when the input/output interface no longer receives a first signal from the communication bus, or to disable the transmitting stage when the receiving stage receives a light signal, and to enable the transmitting stage when the receiving stage no longer receives a light signal.

    摘要： A light fixture defines a first optical path of propagation of a beam of visible light through the interior of a receptacle between a light source and a lighting window, and a second optical path of propagation of a beam of infrared light through the interior of the receptacle to the lighting window with a view to forming a two-way Li-Fi channel for communication of data. The light fixture further includes an optical component that is spectrally selective between the visible and infrared spectra, the component being placed at an intersection of the two optical paths, and being configured to transmit the light beam propagating along one of the optical paths and to reflect the other light beam propagating along the other of the optical paths in order to combine the two, visible and infrared, light beams between the optical component and the lighting window.
