ELECTRONIC SHELF LABEL
First Claim
1. An electronic shelf label arranged to be wirelessly connected to an electronic labeling system, said label comprising:
- a wireless communication interface to receive information to be shown on a display,an internal controller to control the communication interface, the controller being arranged to determine each time an information frame is received, whether or not the information frame is intended for the shelf label,wherein the controller comprises an interface infra-red connection to communicate with a processor, which can assume a sleep mode in which no power is consumed or an active mode in which the processor controls the reception of information from the system to the label, andwherein the controller is arranged to transmit a wakeup signal to the processor if the controller determines that the processor should assume the active mode.
