Abstract: A reprint apparatus may include: a defect checking unit configured to check a defective portion in a solder resist layer of a circuit board; a material filling unit positioned above the circuit board to fill the defective portion with a filling material; and a curing unit configured to cure the material filled in the defective portion. The defect checking unit may be configured to calculate a volume of the defective portion, and the material filling unit may be configured to calculate a discharge amount of the filling material based on the calculated volume of the defective portion, and then discharge the filling material by the discharge amount.

Abstract: A printed circuit board (PCB) includes a solder resist layer including at least one of an opening and a depression and a solder resist patch disposed in at least one of the opening and the depression to have an interface with the solder resist layer in at least one of the opening and the depression.

Abstract: An image sensor package includes a substrate, an image sensor mounted on the substrate, a bonding wire connecting the image sensor to the substrate, a reflector disposed on the image sensor, a sealing member sealing the bonding wire and a portion of the image sensor, and covering at least a portion of the reflector, the sealing member including a hole exposing an effective imaging plane of the image sensor, and a filter attached to the sealing member.

Abstract: A wireless communications method may includes scanning adjacent channels, transmitting a communications request signal to a gateway via any channel among the scanned channels, receiving a communications response signal including information regarding a plurality of data channels from the gateway via the channel through which the communications request signal is transmitted, transmitting an activation request signal to the gateway via any data channel among the plurality of data channels, receiving an activation response signal from the gateway via the data channel through which the activation request signal is transmitted, and registering the data channel through which the activation response signal is received as the data channel for performing data communications with the gateway.

Abstract: An electronic information delivery system, and more particularly, an electronic information label attached to a shelf or the like to deliver information of merchandise displayed in a store is provided. An auxiliary electronic information label is connected to a connector of a main electronic information label. The auxiliary electronic information label includes segment electrodes formed as a circuit pattern on a flexible printed circuit board, and drives a flat panel display panel. One end of the flexible printed circuit board is connected to the connector of the main electronic information label.

Abstract: Disclosed herein are a method for searching for a tag with a communication error and an electronic shelf label system server. The electronic shelf label system server communicating with a plurality of gateways which are installed in a store includes: a gateway identification unit identifying the gateway, which receives a tag signal generated from a tag with a communication error, among the plurality of gateways; a signal attenuation factor measurement unit measuring a signal attenuation factor of the tag signal which is received by the identified gateway; an antenna characteristics measurement unit measuring antenna characteristics of the identified gateway; and a tag position estimation unit determining a spaced distance between the identified gateway and the tag with a communication error and estimating a position of the tag with a communication error based on a position coordinate of the identified gateway and the spaced distance.

Abstract: An electronic shelf label has a simple structure to be easily installed or removed and is attached and detached only through a predetermined-shaped key so as to prevent unauthorized personnel from removing the electronic shelf label, thereby protecting the electronic shelf label from theft.

Abstract: There is provided a bar code made of electronic paper. A bar code made of electronic paper according to an aspect of the invention may include: one or more e-paper stacks having a plurality of pieces of e-paper each having an entire surface displaying black, white or being transparent, wherein an upper level of e-paper of the e-paper stack is narrower than a lower level of e-paper thereof, the outermost layer of e-paper of the e-paper stack has the same width as the narrowest constituting a bar code, and part of the lower level of e-paper exposed by the upper level of e-paper adjacent to the lower level of e-paper has the same width as the narrowest constituent bar of the bar code.

Abstract: The electronic shelf label system includes a management server unit storing product information regarding a product, a gateway unit including a plurality of gateways receiving a message containing the product information from the management server unit, and a plurality of electronic shelf label tag units communicating with the gateways, respectively, the plurality of electronic shelf label tag units each including a plurality of electronic shelf label tags receiving the product information from the gateway and displaying the received product information. The management server unit includes a database storing tag information regarding the electronic shelf label tags and product information displayed on the electronic shelf label tags such that the tag information and the product information are linked together.

Abstract: Provided is a price display apparatus including a plate-shaped label having a price displaying unit; and a holder coupled to one side of the label and having a fixing portion protruding outward from the label.
