Abstract
An electronic label device includes a display device and a microcomputer connected to control the display device. The microcomputer includes a memory having a plurality of registers. Data received via an antenna is stored in the registers. The microcomputer is indirectly controlled to selectively display data stored in the registers on said display device. The indirect control is effected by coupling signals to the said microcomputer without physical contact with elements of the label device, such as by a magnetic reed switch, capacitor coupling or inductive coupling.
Claims24
An electronic label system for receiving and displaying data from a central controller comprising:
- a display device having a display for display of display data thereon;
- said display device having a controller including a memory having registers for storing said display data, said controller being connected to said display to selectively switch said display data from a selected one of said registers to said display to control the display of said display data;
- said display device having first input means for receiving said display data from said central controller for storage in said registers, and a second input means for receiving signals and physically interfacing with said controller and
- means for controlling said controller via said second input means to selectively switch said selected display data in said selected one of said registers to said display for display thereon, said means for controlling being physically unconnected with and out of physical contact with said display device.
