Electronic device, server and method of controlling the same
An electronic apparatus and method of controlling the electronic apparatus are provided. The electronic apparatus includes an operation performer, network communicator circuitry that performs network communication with a server, infrared communicator circuitry, and a processor that controls the operation performer to perform a predetermined operation, obtains information of an external device from a first infrared signal of the external device, is the first infrared signal being obtained through the infrared communicator circuitry, controls the network communicator circuitry to transmit the obtained information of the external device to the server to register the external device as a control target, obtains a control command for controlling the external device from the server, and controls the infrared communicator circuitry to transmit a second infrared signal, which contains command information based on the obtained control command, to the external device to make the external device perform an operation corresponding to the obtained control command.
Miniature embedded self-organized optical network
A self-organizing network of nodes communicates with uncollimated optical pulses. The nodes use low-power, unmoving, broad-beam optical interfaces, low-power processors, and communication algorithms based on timeslots within a timeframe. Nodes self-organize to form the network by pulsing detectors and sources to find neighboring nodes, confirm connections, transmit and store data, and exchange partner node identities. Two- or three-dimensional networks can thereby self-organize without external awareness of network topology, and can repair themselves when nodes move or fail. Node communication may be synchronous, thereby allowing for images of the environment status, and activation of the environment is possible via node stimulators. After forming a network, a cluster of nodes may be read out to provide data from node sensors. Implementation of selected features in the nodes' processors enable formation of networks that are unidirectional, bidirectional, serial, or complex including the formation of meshed networks with adjustable link weights capable of computation.
Dual-mode commercial messaging systems
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.
Data communication with light in controlled environment facilities
Systems and methods for communicating using both radio frequency (RF) communication and light communication (LC) are disclosed. An example device comprises radio frequency communication circuitry, a light communication transmitter; a light communication receiver; a processor for controlling the device according to executable code; and memory for storing data and executable code, wherein the executable code comprises instructions for causing the processor to establish RF communication with an RF access point using the RF communication circuitry; and to establish LC communication with an LC access point using the LC transmitter, the LC receiver, or both.

System and Method for Credential Generation for Wireless Infrastructure and Security
A method, system and computer-usable medium are disclosed for providing a travel network infrastructure. A dedicated Li-F connection is provided for each physical space such as a seat, expected to accommodate a passenger in a travel network such as an airline. A passenger is authenticated according to a physical space occupied by the passenger. If authentication is successful, a secure Li-Fi channel is established for the passenger. The access point of the Li-Fi channel is only leveraged by the passenger and no other passengers.
Method, System, and Computer-Readable Medium for Image Sensor Communication Using Different Sending Data Sequence Rate and Receiving Frame Rate
In an embodiment, a computer-implemented method includes: causing a camera module to capture a plurality of frame portions with an exposure time at a sampling clock period. The frame portions correspondingly reflect a predetermined number of first signal pulses periodically generated by a light source. The exposure time corresponds to a duration of one of the predetermined number of first signal pulses. A first data sequence is encoded into the first signal pulses. The sampling clock period is different from a duration of the first data sequence such that a second data sequence is obtained from cycling through all of the first data sequence.
PATIENT SUPPORT APPARATUSES WITH WIRELESS HEADWALL COMMUNICATION
A person support apparatus includes a first transceiver adapted to wirelessly communicate with a second transceiver of a headwall interface that is positioned off of the person support apparatus. A communication link is automatically established between the first and second transceivers without requiring a user of the person support apparatus to activate a designated control and without requiring the user to identify the headwall interface. The first transceiver includes a unique identifier assigned to the headwall interface in its messages to the headwall interface. The first transceiver may also automatically transmit a disconnect signal to the headwall interface indicating the termination of the communication link is not accidental. The disconnect signal is sent based on one or more of the following: (1) a brake being off, (2) an A/C power cord being unplugged; and/or (3) a signal strength between the transceivers decreasing.
SPATIAL OPTICAL WIRELESS COMMUNICATION SYSTEM
A system comprising a plurality of points of access deployed in venue having a crowd area located next to an event happening area, each one of the plurality of points of access comprising an optical transmitter adapted to broadcast an encoded media stream in light emissions, a plurality of portable optical receiver units, each having: a connector adapted to be electrically connected to one of a plurality of client devices, an optical receiver adapted to capture the light emissions, and a controller adapted to convert the light emissions into a digital stream forwarded via the connector to a respective client device of the plurality of client devices to allow a presentation of the digital stream on a display of the respective client device by an application executed on the respective client device.
DUAL-MODE COMMERCIAL MESSAGING SYSTEMS
Provided are, among other things, systems, methods and techniques for providing remote location-based customer service for in-store customers. One such system includes: (a) a central server; (b) wireless transceivers coupled to the central server at different locations within each of multiple different retail shopping sites; and (c) handheld wireless devices, carried by customers at such retail shopping sites and in wireless communication with such wireless transceivers. Each of the handheld wireless devices is configured with a user interface that allows a customer to designate a user-interface element to request a customer-service session. Upon designation of the user-interface element on one of such handheld wireless devices, the request is forwarded to the central server. The central server establishes a two-way real-time communication link between the handheld wireless device and a customer-service representative.
