SYSTEMS AND METHODS FOR CONNECTING AND CONTROLLING CONFIGURABLE LIGHTING UNITS

Nanogrid Limited, Sheung...

1. A method for layout detection performed by a controller coupled to an assembly of configurable lighting units, the method comprising:deriving an array of integers based on data indicative of coupling characteristics between individual configurable lighting units of the assembly of configurable lighting units arranged in a continuous shape through a set of one or more physical connections, such that any two potential assemblies that are geometrically distinct apart from translation or rigid-body rotation generates distinct arrays of integers, and such that any two potential assemblies that are geometrically indistinct following translation or rigid-body rotation, generates identical arrays of integers; and
storing the array of integers in a data structure encapsulated in non-transitory computer readable media residing on or in communication with the controller.
