An interactive multimedia, two-way notification system and method transforms a notification message into a dynamic marketing channel. Several locking elements are arranged in the annular groove. The angle of the first metallic material to a free edge of the first metallic material, at an end portion of a joined surface between the first and second metallic materials, is greater than or equal to 120 degrees or in the range of from 55 degrees to 85 degrees. The parsing module employs a probabilistic approach to parsing the input-output examples. The receiver also comprises error detection circuitry for detecting an error in a packet that comprises the group of bits. The method includes sequentially stacking a display panel and a lenticular sheet on a stage, irradiating light that is incident in parallel toward the display panel and the lenticular sheet from below the display panel, detecting the light that has passed through the display panel and the lenticular sheet, and determining an axial direction of a columnar lens formed on the lenticular sheet.
