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 EMF 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 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 decorative self powered element and receiving power therefrom,

c. an antenna is capable of receiving EMF energy;

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

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

wherein said plurality of slave decorations, each includes a selection of switchable EMF frequency responsive filters allow a user to select which EMF frequency and wherein the master source generator of EMF energy generator includes a plurality of EMF transmission frequencies matched to the selection of slave frequencies.

2. 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 decorative self powered element and receiving power therefrom,

c. an antenna is capable of receiving EMF energy;

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

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

wherein said plurality of slave decorations, each includes a selection of switchable EMF frequency responsive filters allow a user to select which EMF modulations and wherein the master source generator of EMF energy generator includes a plurality of EMF transmission modulations matched to the selection of slave modulations.

3. A system of improved EMF responsive decorative lighting having a source of EMF and a plurality of illuminated light 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 plurality of illuminated light decorative elements including a coded receiver capable of selectively receiving a plurality of EMF signals from the source of EMF.

4. The system of claim 3 wherein said plurality of illuminated light decorative elements including switchable and tuning capable of receiving at least some of said coded EMF signals.
