摘要： The present invention relates to a simple data transmission protocol and a data receiving device (10, 10′, 10″, 10′″) for a power over Ethernet system (100′) using the simple data transmission protocol. The device (10, 10′, 10″, 10′″) comprises a port and a simple logic unit. The port is configured for receiving power and data transmitted to the device (10, 10′, 10″, 10′″) via an Ethernet connection (16′). The simple logic unit is configured to decode data encoded in a characteristic of one or more data packets received at the port. The data can be encoded in data packet length, data packet duration, number of data packets in a predetermined interval, and/or sequence of data packets. The simple data transmission protocol can reduce power consumption as in contrast to the Ethernet protocol MAC does not need to be decoded for information transfer. Hence only simple logic functions are required.

摘要： A communication system, method and apparatus that enable combined illumination and communication of data (e.g. LiFi) by achieving extended coverage using just three or more channels. The combined illumination and communication system comprises an arrangement of luminaires as a regular Bravais pattern based on a convex quadrilateral unit cell on the ceiling. Using a spatial reuse pattern of at least three optical color channels, full coverage for the users in that space can be achieved. The predetermined reuse pattern is configured so that a first channel and a second channel are distributed over the Bravais pattern and a third channel is used to cover dead spot areas where the coverage areas of the first and second channels contact each other. Interference can be avoided to achieve full contiguous coverage without requiring the luminaires to synchronize or to communicate with each other.

摘要： A converter for driving a load has a main switch for controlling, at a switching frequency, the path of current flow through a power inductor and power commutation thereof so as to provide an output. A hysteretic control circuit generates a burst signal for turning on and off the power commutation to implement a burst mode operation with a burst frequency lower than the switching frequency. An adjusting circuit adjusts the upper threshold and/or the lower threshold of the hysteretic control in dependence on the detected burst signal. This burst mode hysteresis controlled converter in this way has the hysteresis adapted in dependence on the load being driven so that load regulation problems are reduced.
