摘要： A communication system includes a cloud server that further includes a processor. The processor obtains sensor data associated with a defined indoor area and a plurality of optical nodes in defined indoor area. The processor further obtains location coordinates of the plurality of optical nodes in the defined indoor area. The processor then causes the master communication device to form a laser beam-based wireless communication network in the defined indoor area based on the obtained sensor data and the location coordinates of the plurality of optical nodes.

摘要： Provided is an in-store dual-mode communication system in which shelves are disposed within a commercial space. A server is coupled to the Internet and/or a wide-area network and is configured to send and receive communications. Also provided are light-based messaging units that are located on and/or attached to such shelves, each: 1) having a light source, 2) receiving a communication from the server, and 3) in response to receipt of such communication, turning the light source on and off so as to broadcast a digital message that was included within such communication, as a binary-encoded digital signal corresponding to on/off states of the light source. A user device: (i) receives, via its light sensor, and then decodes the binary-encoded digital signal from a light-based messaging unit in order to obtain the digital message that corresponds to it; and also (ii) communicates with the server via its wireless interface.

摘要： Useful data is transmitted to a terminal existing in a transportation vehicle. A communication apparatus installed in the transportation vehicle and configured to transmit the data to the terminal existing in the transportation vehicle includes a data selection unit and an illumination unit. The data selection unit acquires location information indicating a location of the transportation vehicle in which the terminal exists and which is traveling. Based on the acquired location information, the data selection unit selects approaching-location data related to a location ahead of a current location of the transportation vehicle in a traveling direction from a plurality of pieces of data related to the location. The illumination unit transmits, as a modulated light signal, a signal comprising the approaching-location data.

摘要： A first optical routing device that includes a mounting component and an optical routing component attached to the mounting component. The mounting component includes a rechargeable battery to power operations of the first optical routing device and a processor that communicates over-the-air with a master communication device or one or more service communication devices via RF supervisory links. The processor receives an instruction via the RF supervisory links to control a movement of the mounting component along with the optical routing component such that an angle or a direction of deflection of laser beams from an optical routing component of optical routing device is changed. The processor performs a range measurement to compute a distance between the first optical routing device and an optical node. The optical node is one of a second optical routing device, the master communication device or one of the one or more service communication devices.

摘要： This invention relates to a power supply system for an optical wireless communication system where a modem (212) is connected to a plurality of transceivers (11). The underlying idea being that the transceivers (11) are powering the modem (212), rather than the modem (212) powering the transceivers (11). To achieve this, a power combiner is provided that can receive power from the transceivers (11). The transceivers (11) power down when no endpoint is detected and use a subset of emitters, in which case the modem (212) can also be switched to a lower power mode.

摘要： A user device may use a light communications system to detect, from a light source in a physical space, light in a pattern that represents encoded information. The light communications system may include a sensor and an emitter. The user device may decode the encoded information based on the pattern to cause an update associated with a virtual meeting. In some implementations, the update may include the user device joining the virtual meeting using a meeting identifier. In some implementations, the update may include adjusting a microphone or a speaker in the physical space. In some implementations, the update may include a pairing between the user device and a second device that enables bidirectional communication between the user device and the second device.

摘要： Aspects of the present disclosure describe techniques for controlling coherent crosstalk errors that occur in multi-channel acousto-optic modulators (AOMs) by applying cancellation tones to reduce or eliminate the crosstalk errors. For example, methods and systems are described that include calculating initial radio frequency (RF) tones to be applied to multiple channels of the AOM; calculating, in response to an application of the initial RF tones, compensation RF tones to be added to the initial RF tones to at least partially correct for undesired crosstalk effects; and in response to the application of the initial RF tones and the compensation RF tones, calculating subsequent compensation RF tones to be added to the initial RF tones until the crosstalk effect in each of the multiple channels is below a threshold level.

摘要： The present disclosure provides an infrared communication method and apparatus, a storage medium, and an electronic apparatus. The method includes: transmitting a first infrared signal to a target communication terminal, where the first infrared signal is an infrared signal encoded based on a level duration; and in a case that a second infrared signal replied by the target communication terminal based on the first infrared signal is received within a first target duration, transmitting a third infrared signal to the target communication terminal. By using the above technical solution, a problem that bidirectional information interaction cannot be performed due to the inability of distinguishing bidirectional infrared signals in the infrared communication method in the related art is solved.
