Abstract

A system and method of controlling self powered decorative devices using EMF emanating from, for example, a light string on a Christmas tree. The decorative devices sense the presence of EFM from the light string and actuate in response thereto and turn off when the field disappears, thereby saving energy. In an alternate embodiment, the EMF source is capable of modulation and the slave decorations are coded and tuned to specific EMF characteristics, such as frequency. The master EMF source transmits the EMF of different characteristic thereby causing the coded slave decorations to operate in a synchronized matter. The system may also be responsive to music or other inputs to create special decorative effects.

Claims

1. A system for remotely controlling the actuation of battery operated decoration which is proximate a master source of EMF energy, such as a light string, comprising:

a. a decorative element having an integral power supply,

b. an EMF receiver powered by said power supply,

c. an antenna capable of receiving EMF energy;

d. a detector response to EMF energy; and

e. a switch operated by said detector which actuates the element when EMF energy detected by said receiver is present and deactivates said element when not present.

2. The system of claim 1 wherein said detector includes a rectifier circuit coupled to a bandpass filter.

3. The system of claim 1 wherein said detector includes a tuned R-C network.

4. An illumination system for an ornament having a switchable source of EMF energy running therethrough and emitting EMF energy, comprising

a. at least one illuminated decorative elements having an integral power supply,

b. an EMF receiver powered by said power supply and integral to said element,

c. an antenna for receiving EMF energy;

d. a tuned detector turned to be responsive to the EMF energy emitted by said ornament, and

e. a switch operated by said detector which operates the actuation of the ornament in response to EMF.

5. A intelligent control system for remotely controlling the switching of at plurality of slave decorations by a master source generator of EMF energy, comprising

a. a plurality of decorative self powered elements,

b. an EMF receiver associated with each element and receiving power therefrom,

c. an antenna capable of receiving EMF energy;

d. a tuned detector response to EMF energy of a predetermined characteristic; and

e. a switch operated by said detector which operates the element in a predetermined pattern when EMF energy of said desired characteristic is detected by said receiver and operates the element in a second predetermined pattern when not present.

6. The system of claim 5 wherein one of said predetermined patterns is a sleep mode, wherein said receiver is flash actuated periodically and then returns to an off mode.

7. The system of claim 5 wherein said plurality of slave decorations each include a selection of switchable EMF frequency responsive filters allowing the user to select which EMF frequency the element will be response to and wherein the source generator includes a plurality of EMF transmission frequencies matched to the selection of slave frequencies.

8. The system of claim 5 wherein said plurality of slave decorations each include a selection of switchable EMF frequency responsive filters allowing the user to select which EMF modulations the element will be response to and wherein the source generator includes a plurality of EMF transmission modulations matched to the selection of slave modulations.

9. A system of improved EMF responsive decorative lighting having a source of EMF and a plurality of illuminated slave decorative elements having self contained power supplies, the improvement comprising:

a. the EMF source including the capability of generating a plurality of coded EMF signals

b the slave elements including a coded receiver capable of selectively receiving a plurality of EMF signals from the source.

10. The system of claim 9 wherein said slave elements including switchable tuning capable of receiving at least some of said coded EMF signals.

11. A method of wirelessly controlling individual lighting elements of an ornamental fixture having a light string threaded through the fixture comprising

a. detecting EMF generated by the light string,

b. actuating the lighting elements when an EMF is present proximate the light string,

c. deactivating the lighting elements when the EMF is no longer present, so that energy needed for the lighting element is preserved when the light string is no longer illuminated.
