The invention relates to powering one or more devices, in particular in the context of Power-over-Ethernet (PoE). In an embodiment of the invention, it is proposed to equip each node () with a PD interface () that can signal multiples of the standard defined unity load (25 k&#x3a9; with tolerances) during the detection process and increase the load during a sequence of detection attempts. In that way, several nodes () can share one PSE outlet and determine the number of neighboring loads (). At the same time, each node () will offer full functionality during 'normal' stand-alone wiring. This powering concept can be combined with full or limited data communication capabilities.

Provided is a lighting device including a light source for emitting light, a sensor configured to detect infrared radiation from a plurality of locations along a path in the field of view of the sensor, at least one attenuation element arranged between at least one location of the plurality of locations and the sensor so as to attenuate or block infrared radiation emitted from the at least one location before it reaches the sensor, and a controller. The at least one attenuation element is further arranged in relation to the field of view of the sensor for the signal output from the sensor to indicate, when an occupant is moving along the path, a direction of movement of the occupant along the path. The controller is arranged to control the light source based on the direction of movement of the occupant, and a cover plate is arranged between the at least one location of said plurality of locations and the sensor, and also arranged between the at least one location and the light source, wherein the cover plate is transparent or translucent to said visible light, wherein the at least one attenuation element forms part of the cover plate, and wherein outside, or away from, the attenuation element, the cover plate is at least partly transparent to infrared radiation.

Lighting device with motion sensor

The present invention relates to Power-over-Ethernet (PoE) systems. The invention proposes to use a classification event to communicate from the PD () to the PSE (). A sensor () may determine a sensor value, shut down the PoE connection, and reconnect so that the power up cycle with the PSE () will start. The sensor () provides a PoE resistance related to a class 0, 3 where the class relates to the sensor value (e.g., class 0=presence detected; class 1=no presence detected). This procedure may be repeated (e.g. continuously, every minute or whenever the sensor value changes such that the PSE () needs to be informed) and if needed multiple cycles can be used to increase the length of the message communicated.
