In one aspect, the present disclosure relates to a self identifying light source including an emitter that produces visible light; and an autonomous modulator in electrical communication with the emitter that automatically and continually modulates the visible light produced by the emitter, wherein the modulated visible light represents an identification code of the light source. In some embodiments, the emitter is a light emitting diode (LED) and further comprises an LED driver that provides a specified voltage and current to each LED in the light source.

A method for facilitating space experiences for at least a first space user and for at least first and second different spaces, the method comprising the steps of storing first and second space experience specifications for the first and second different spaces, respectively, wherein the first and second space experience specifications indicate space affordance settings for the first and second spaces, respectively, sensing a trigger event associated with at least one of the first and second different spaces, where the sensed trigger event is associated with the first space, using the first space experience specification to control the first space affordances and where the sensed trigger event is associated with the second space, using the second space experience specification to control the second space affordances.

Provided herein an apparatus for generating plasma, the apparatus including a nozzle array, first electrode, and housing. The nozzle discharges plasma. The first electrode is disposed to surround the nozzle array. The housing is disposed to surround the nozzle array and first electrode. The nozzle includes a plurality of nozzles disposed adjacent to one another and in the form of an array, each nozzle configured to discharge plasma. Therefore, it is possible to generate a large size plasma evenly and stably.
