Patent ID: 8164439

Claim:
A system for establishing a compliance zone and interacting therewith, the system comprising: a compliance zone designator configured to transmit data using an ultrasound signal in such a way that results in creation of the compliance zone in a vicinity of the compliance zone designator, the ultrasound signal comprising a plurality of bursts, wherein consecutive bursts within the plurality of bursts are separated in time by predefined time intervals, and wherein a sequence of all the predefined time intervals between the consecutive bursts within the plurality of bursts uniquely identifies the compliance zone; and a wearable device separate from the compliance zone designator, the wearable device comprising a compliance zone recognition component configured to identify a pre-defined interaction criterion for the compliance zone when the wearable device receives the data through the ultrasound signal within the compliance zone; wherein upon the wearable device being disposed within the compliance zone, the compliance zone recognition component identifies the interaction criterion of the compliance zone and operates in accordance with the interaction criterion.
