At least one of the first and second electrodes, e.g., an upper electrode, includes an oxygen diffusion blocking material, e.g., oxygen atoms, at a concentration that decreases in a direction away from the dielectric region. The at least one of the first and second electrodes may include a first layer having a first concentration of the oxygen diffusion blocking material and a second layer on the first layer and having a second concentration of the oxygen diffusion blocking material less than the first concentration. The at least one of the first and second electrodes may further include a third layer on the second layer and having a concentration of the oxygen diffusion blocking material less than the second concentration. | 03-05-2015 |
20150363742 | INVENTORY MANAGEMENT APPARATUS AND METHOD - An inventory management method for managing warehouse inventory and in-store inventory in real time. An inventory management apparatus is able to calculate inventory based on received inventory information and identification information of small electronic labels assigned to products. By generating an image frame, which includes the inventory information, and transmitting the image frame through a gateway to an electronic label, the inventory management apparatus allows the electronic label to display the image frame. The inventory management method and apparatus allows a location of a product to be informed in real time, so that a product ready to be run out inside a store may be replenished immediately. | 12-17-2015 |
20150363806 | PRODUCT PRICING APPARATUS FOR ELECTRONIC INFORMATION LABEL SYSTEM AND METHOD THEREFOR - An apparatus and method for determining a product price for an electronic information label (EIL) system. The apparatus identifies customer interest in a particular product based on customers and their behaviors that express interest of a product, and determines a price for the product based on the customer interest. The apparatus may first determine a basic price of the product according to an existing method, and then determine a final price by adjusting the basic price, taking into account customer interest, and, if needed, the sales of the product. The determined product price may be transmitted to the EIL system and then be displayed on an EIL tag. | 12-17-2015 |
20160041645 | TOUCHSCREEN DEVICE, METHOD OF SENSING TOUCH INTERACTION, METHOD OF GENERATING DRIVING SIGNALS, AND METHOD OF CREATING DRIVING MATRIX - A touchscreen device may include a driving circuit unit simultaneously applying predetermined driving signals to N first electrodes among a plurality of first electrodes, N being a natural number equal to or greater than two, a sensing circuit unit detecting levels of capacitance from a plurality of second electrodes to output sensing signals, and an operation unit determining an occurrence of a touch interaction, based on the sensing signals. The driving circuit unit determines at least one column in which a sum of elements is equal to a peak value, selects one row having a highest number of elements having a maximum level from rows of the at least one column, creates a first matrix by inverting levels of elements in the selected row, and generates the driving signals according to a driving matrix created based on the first matrix. | 02-11-2016 |
