Apparatus for transferring information between electronic display devices and means for transmitting and receiving information and for supplying operating current to the electronic display devices
First Claim
1. A system for displaying information transferred between a fuel dispensing nozzle and a remotely located information receiving and transmitting data source comprisinga nozzle operative for the dispensing of fuel.a data source located at a site remote from said nozzle,an information display device on said nozzle for displaying information data pertaining to fuel being dispensed,a battery energized operating circuit located inside said nozzle for supplying operating current to said display device.energizing means operative only when said nozzle is inoperative for transferring electrical energy to said operating circuit, said energizing means including a first inductive means connected to said operating circuit and located inside said nozzle and a second inductive means for coupling electromagnetically with said first inductive means located outside said nozzle, andinformation conductor means connecting said display device with said data source for conducting information between said display device and said data source.

Abstract
Apparatus for transferring information between an electronic display device and means for transmitting and receiving information and for supplying operating current to the electronic display device. The operating current is provided by a battery and the apparatus includes an operating circuit having an energizing means which charges the battery when the apparatus is not in use. The energizing means includes first inductive means located inside the fuel dispensing nozzle and second inductive means for coupling electromagnetically with the first inductive means located outside the nozzle. Conductors are arranged between the display device and the information transmitting and receiving means to provide safe transfer of information between them.
