The method includes determining a pattern of the change in luminance by modulating the signal to be transmitted, and transmitting the signal by a light emitter changing in luminance according to the determined pattern, wherein the pattern of the change in luminance is a pattern in which one of two different luminance values occurs in each arbitrary position in a predetermined duration. In the determining, the pattern of the change in luminance is determined so that a luminance change position in the duration is different for each of different signals to be transmitted, the luminance change position being a position at which the luminance rises or a position at which the luminance falls. | 2016-04-21 |
20160112129 | Resource Allocation in PON Networks via Wave-front Multiplexing and De-multiplexing - A data communication system comprises a wave-front multiplexer configured to wave-front multiplex first electronic signals into second electronic signals, an electronic-to-optical converter configured to convert a third electronic signal carrying information associated with said second electronic signals into a first optical signal; an optical transferring module configured to split said first optical signal into second optical signals, wherein each of said second optical signals carries substantially the same data as said first optical signal carries; optical-to-electronic converters configured to convert said second optical signals into fourth electronic signals; wave-front demultiplexers each configured to wave-front demultiplex one of said fourth electronic signals into fifth electronic signals substantially equivalent to said first electronic signals respectively. | 2016-04-21 |
20160112130 | INTERCOM TRANSCEIVER WITH FIBER OPTIC LINK - A system and method for carrying a downstream optical signal and an upstream optical signal on a fiber optic link is disclosed. The system and method includes a first transceiver unit that receives an input communication signal from at least one external communication device at an electrical input port, a transmitter that converts the input communication signal into an optical signal and transmits the optical signal as an downstream optical signal on a fiber optic link, a receiver at the second transceiver unit that receives the downstream optical signal and converts the downstream optical signal into an electrical communication signal, and a first circuit in the second transceiver unit that determines whether the second transceiver couples the electrical communication signal to a two wire intercom circuit or a four wire intercom circuit. | 2016-04-21 |
