A fiber enabled optical wireless communication (FE-OWC) system and method is provided. An optical antenna composed of an optical fiber transceiving port array and a lens or a reflecting mirror is used to generate optical beams in different directions, such that full-beam coverage of a communication area is implemented. The optical antenna is connected to an optical chain by an optical fiber, the optical chain realizes mutual conversion of an optical signal and an electrical signal, and a baseband signal processing unit which is in electrical signal connection with the optical chain realizes user scheduling, transceiving signal processing, etc. Multi-user multiple-input multiple-output (MIMO) or massive MIMO or beam division multiple access optical wireless communication between a base station and user terminals is implemented by using the optical beams. The FE-OWC system and method may support ultra-high-rate user data transmission and system throughput, and have a low complexity.

One information processing device may comprise circuitry configured to cause an image to be displayed on a display together with a superimposed light component having a characteristic that changes as a function of time and represents a code to be processed by a receiving terminal. Another information processing device may comprise circuitry configured to process image data from an image sensor, which image data represents an image generated on a display together with a superimposed light component having a characteristic that changes as a function of time, to identify a code represented by the superimposed light component.

A method to securely transfer data to aid in a medical procedure or to a data management system to be accessed in a medical care facility is provided that includes a set of data from a data storage system being downloaded via a network to a visible light communication (VLC) enabled device. The set of data from the VLC enabled device is then transferred to a VLC enabled device located in an operating room (OR) via point to point VLC or uploaded to a data management system. The transferred set of data is then used to aid in a medical procedure or be accessed by a medical care facility. Software executables are similarly transferred and run in an OR context.

The present application relates to an optical signal receiving apparatus, including a housing for accommodating a body inside the housing, where the body is provided with an optical receiver for receiving an external optical signal, and an optical-to-electrical conversion device is arranged at a central position of the optical receiver. The optical signal receiving apparatus is further provided with a lamp cup for reflecting the external optical signal to the optical-to-electrical conversion device, a light ring for indicating a light incident region, a pry-proof circuit arranged on the body, a power control circuit, and a keying circuit. The optical signal receiving apparatus of the present application can improve user experience.

In a positioning system, a mobile device can detect a transmission from one of a number of lighting devices to obtain an identification (ID) label or code of each lighting device. The mobile device uses the detected ID code for a lookup in a self-stored or remotely stored table that associates lighting device location information with ID codes, to obtain an estimate of mobile device position. To mitigate against hacking by a third party detecting the ID codes and observing locations to compile its own lookup table, the disclosed examples dynamically alter the assignments of particular ID codes to the lighting devices, while minimizing potential disruption of position determination service for mobile devices due to the changes to ID code assignments.
