摘要： A method for providing visible notification by a device in a visible-light-communication system based on Institute of Electrical and Electronic Engineers (IEEE) standard 802.15.7, wherein higher levels are allowed to invoke through one standardized interface a medium-access-control sub-layer to provide color-function support and enables invocation of a transmission of color, visibility, and dimming frames by a higher layer, which creates a unified interface between the MAC sub-layer and the higher layers, while providing a primitive for requesting, by the at least one upper layer to the at least one interface of the medium-access-control entity layer, a transmission of at least one visibility frame.

摘要： In a method for transmission of digital data in an optical free-space transmission system in which a binary code sequence produced from the digital data is used to transmit amplitude-modulated light waves across an optical free space between a transmitter and a receiver, according to a first aspect, the binary code sequence is produced such that a modulation frequency of the light waves determined by the binary code sequence has a value of 70 Hertz. According to a second aspect, ‘t’ light waves are modulated with the binary code sequence and binary data are transmitted in blocks during a first time period, and non-modulated light waves are emitted during second time periods, wherein the light intensities of the time periods are selected so that the quantities of light transmitted in two periods correspond to predetermined quantities of light.

摘要： In a method for optically transmitting data by means of a pulse-width-modulated light source (LED), a pulse duty factor (N) of a pulse width modulation is specified to set the brightness of the light source (LED). A bright time (T) is divided into at least a first and second partial bright time using at least one blanking so that the data (DATA) to be transmitted are encoded by the start and time length of the at least one blanking. The sum of the partial bright times within the pulse width modulation cycle substantially corresponds to the bright time according to the specified pulse duty factor.
