Abstract
Official abstract text for this publication.
In one example implementation in accordance with the present disclosure, a process is provided. The process includes entering a first mode of operation where a plurality of light sources are permitted to illuminate. The process further includes entering a second mode of operation where the plurality of light sources associated with the first switch are not permitted to illuminate, and where the entering of the second mode of operation is in response to not detecting a presence for a time period. The process still further includes entering a third mode of operation in response to receiving a command, where only a subset of the plurality of light sources are permitted to illuminate and the remainder of the plurality of light sources are not permitted to illuminate.
