An acoustically activated marketing for displaying predefined information in response to predefined data being received. The device is obtained from a retailer and worn as a badge while at the cinema or while listening to the radio or TV. When a specific advertisement is broadcast, the badge interprets part of the sound track and activates the display on the badge. The displayed information may be an advertisement or a message. The predefined data may be broadcast by a commercial broadcasting means, such as a television or radio.

Acoustically activated marketing device

A phased array system comprising a plurality of elements each element being arranged to transmit/receive signals with a predetermined phase and/or amplitude with respect to other elements of the array, whereby a beam steering function is afforded, each element of the array including a transducer, the trnasducers of the array elements being placed in communication with at least three reference stations which are spaced apart in three dimensions such that data communication between each transducer and the reference stations can be used to define the position of each element relative to the stations and wherein the phase and/or amplitude of signals transmitted and/or received by the elements is determined in dependence upon the said relative position thus defined, whereby improved beam steering accuracy is afforded.
