Patent ID: 7723647

Claim:
A hot melt adhesive material dispensing system comprising: an adhesive supply unit (ASU) for providing a supply of hot melt adhesive material to be dispensed; at least one electrical component disposed upon said adhesive supply unit (ASU); an applicator head for dispensing hot melt adhesive material supplied to said applicator head by said adhesive supply unit; at least one electrical component disposed upon said applicator head; a hot melt adhesive material hose assembly having opposite ends thereof fixedly connected to said adhesive supply unit (ASU) and said applicator head for conducting hot melt adhesive material from said adhesive supply unit (ASU) to said applicator head; a wire incorporated within said hot melt adhesive material hose assembly; a first signal coupler disposed upon said adhesive supply unit (ASU) for receiving a multiplicity of data, information, and control signals from said at least one electrical component disposed upon said adhesive supply unit (ASU); and a second signal coupler disposed upon said applicator head for receiving a multiplicity of data, information, and control signals from said at least one electrical component disposed upon said applicator head, wherein said multiplicity of data, information and control signals are conveyed between said at least one electrical component disposed upon said adhesive supply unit (ASU) and said at least one electrical component disposed upon said applicator head by means of said wire incorporated within said hot melt adhesive material hose assembly as a result of said wire, incorporated within said hot melt adhesive material hose assembly, serving as a carrier for said multiplicity of data, information, and control signals which are overlayed onto said wire by said first and second signal couplers such that said multiplicity of said data, information, and control signals are transmitted from said at least one electrical component disposed upon said adhesive supply unit (ASU) to said at least one electrical component disposed upon said applicator head, and from said at least one electrical component disposed upon said applicator head to said at least one electrical component disposed upon said adhesive supply unit (ASU).
