Abstract:
A signalling apparatus comprising: a non-light-emitting element arranged to transmit and/or reflect light from a light-emitting element, the non-light-emitting element having a variable transmission and/or reflectance respectively, and the non-light-emitting element being separate from the light-emitting element; and a controller configured to control the transmission and/or reflectance of the non-light-emitting element in order to temporally modulate the light and to thereby embed data into the light in a manner imperceptible to human vision; wherein the non-light-emitting element is arranged to transmit and/or reflect the light towards a detecting apparatus housed in a unit separate from the light-emitting element and non-light-emitting element, in order for the embedded data to be detected by the detecting apparatus.

Claim (Index 14):
A signalling method comprising:\n using a non-light-emitting element to transmit and/or reflect visible light emitted from a light-emitting element, the non-light-emitting element having a variable transmission or reflectance respectively, and the non-light-emitting element being separate from the light-emitting element at least in that the non-light-emitting element and the light-emitting element are not housed together in any same unit, wherein the transmission or reflectivity of the non-light-emitting element is variable in that across an area of the non-light-emitting element the transmission or reflectance can be varied only uniformly, such that said modulation is performed by temporally varying the transmission or reflectance uniformly across said area; controlling the transmission or reflectance of the non-light-emitting element in order to modulate the light at a frequency beyond human visual perception, and to thereby imperceptibly embed data into the light in a manner imperceptible to human vision; directing the transmitted or reflected the light towards a detecting apparatus housed in a unit separate from the light-emitting element and non-light emitting element, such that the embedded data is detected by the detecting apparatus.
