摘要： Provided is a computing technology for controlling information display of an electronic shelf label that is connected to a management server via a network and displays electronic information. The electronic shelf label measures a distance to at least one product arranged behind the electronic shelf label, and when a change in the distance occurs, activates a wireless tag reader. When product identification information acquired by the wireless tag reader is different from currently displayed product identification information, the electronic shelf labels request a label change registration to a server. Changed product information is received according to the label change registration, and the changed product information is reflected in displayed product information.

摘要： A transformer includes a magnetic core, a first coil unit and a second coil unit. The first coil unit is disposed within the magnetic core and includes a laminated board having layers laminated therein and conductive patterns. Respective ones of the conductive patterns are disposed on the laminated layers. The second coil unit includes a conductive wire spaced apart from the conductive patterns of the laminated board by an insulating distance. The conductive wire includes a triple-insulated wire surrounded by three sheets of insulating paper to maintain the insulating distance from the conductive patterns.
