Abstract
According to one exemplary embodiment, an apparatus, system and method for a remotely powered optical output label is disclosed. The system includes a transmitting device including at least one transmitting antenna and a power source. A receiving label is in remote communication with the transmitting device, the receiving label including a receiving antenna and a capacitor connected to at least one optical element. The optical element may be selectively controlled and powered to variably emit light using energy transmitted by the transmitting device.
Claims8
A method of variably controlling the optical output of a label comprising:
- arranging the capacitance of a first optical element to be resonant with a first receiving antenna of a receiving label at a first frequency and arranging the capacitance of a second optical element to be resonant with a second receiving antenna of the receiving label at a second frequency;
- transmitting energy from a remote transmitting device at said first frequency and at said second frequency;
- receiving energy from the transmitting device at the first receiving antenna at said first frequency to activate the first optical element and receiving energy from the transmitting device at the second receiving antenna at the second frequency to activate the second optical element;
- and
- selectively controlling the output of the first and second optical element by varying factors associated with the energy transmitted by the transmitting device.
