1. A device, comprising:
- a housing; and
a circuit wherein the circuit further comprises;
a display element coupled to the housing;
a first coil coupled to the display element and the housing; and
a rectifier circuit coupled between the display element and the first coil;
wherein the circuit further comprises an amplitude switch coupled between the rectifier and the display element;
further comprising a second amplitude switch and a second display element, wherein the second amplitude switch is coupled between the rectifier and the second display element, the first amplitude switch turns off in response to receiving a voltage from the rectifier outside a first range of the voltage, the second amplitude switch turns off in response to receiving the voltage outside a second range of the voltage, and the first and second ranges are different from one another.

Abstract
A system and method are described in which power is inductively supplied to a product or a package containing a product. This power is received via a coil and used by a light source to further enhance the presentation of the product or packaging. The illuminated light draws more attention to the product or package and thereby increases the probability that a prospective buyer will buy the product. Power is supplied to the package via a coil mounted to a shelf system. The frequency of the power supplied to the shelf coil may be changed to change the frequency at which the light source in the product or package illuminates.
