Methods and apparatus for identifying electronic shelf labels with which communication has been lost

摘要

Systems and techniques for calling attention to loss of communication with an electronic shelf label. One or more of a plurality of labels deployed in a location may be programmed with a message to be displayed or an action to be taken if communication is lost. The labels may be programmed with a scheduled action that will cause a label to take the programmed action or display the programmed message if communication with the label does not occur by a specified time. Communication with the label causes the action or event to be rescheduled.
