Patent ID: 7701078

Claim:
Aircraft retrofit remote load controlling apparatus for retrofitting an aircraft having a preexisting conductor bus, the apparatus comprising the combination of: a newly added electrical energy to alternate form energy transducer load element received in remote location mounting in said aircraft; a source of transducer load element energizing direct current electrical energy located within said aircraft; a preexisting electrical conductor in said preexisting conductor bus joining a central location of said aircraft with said remote location, said preexisting conductor connecting said newly added electrical energy to alternate form energy transducer load element through a remote transducer control element to said source of transducer energizing electrical energy; and a newly added central location electrical conductor energization controller including a source of sinusoidal alternating current electrical energy modulating said transducer energizing direct current electrical energy received in said preexisting electrical conductor and in said remote transducer control element in response to a selection signal input to said newly added energization controller; said remote transducer control element determining characteristics of said energizing electrical energy received in said new energy transducer load element in accordance with said sinusoidal alternating current electrical energy modulating of said transducer energizing direct current electrical energy received in said preexisting electrical conductor and in said remote transducer control element in response to a selection signal input to said newly added energization controller.
