Researchers Submit Patent Application, "Device and Method for Detecting Insertion Direction of Sim Card", for Approval

July 16, 2014



By a News Reporter-Staff News Editor at Electronics Newsweekly -- From Washington, D.C., VerticalNews journalists report that a patent application by the inventors Kim, Kyung-Up (Gyeongsangbuk-do, KR); Son, Je-Hyun (Gyeonggi-do, KR), filed on December 20, 2013, was made available online on July 3, 2014.

The patent's assignee is Samsung Electronics Co., Ltd.

News editors obtained the following quote from the background information supplied by the inventors: "In order to prevent a reversed insertion of a SIM card when the SIM card is inserted into a terminal, a push-push type SIM card is configured such that the reversed insertion is mechanically prevented by a SIM card socket unit of the terminal. In addition, a socket type SIM card is configured such that when the SIM card is inserted into a SIM card socket unit of the terminal in the reversed direction, the reversed insertion can be visually discriminated using the asymmetry of the SIM card.

"However, as the size of a SIM card is reduced, the asymmetry portion in a socket type SIM card is also reduced. As a result, it becomes difficult to visually discriminate whether or not the SIM card is reversely inserted into the SIM card socket unit of the terminal.

"Also in case of a push-push type SIM card, as the size of the SIM card is reduced, it is expected that a mechanical design that allows the reversed insertion of the SIM card into the SIM card socket unit of the terminal to be detected may become very difficult, and even if such a design is enabled, the reversed insertion of the SIM card may not be confirmed when the reversed insertion of the SIM card is forcibly performed."

As a supplement to the background information on this patent application, VerticalNews correspondents also obtained the inventors' summary information for this patent application: "To address the above-discussed deficiencies of the prior art, it is a primary object to provide at least the advantages described below.

"Another aspect of the present disclosure is to provide a device and method for detecting a reversed insertion of the SIM card into a SIM card socket unit in a terminal.

"Yet another aspect of the present disclosure is to provide a device and method capable of informing a user of a reason why a SIM card inserted into the SIM card socket unit of the terminal is not recognized.

"Yet another aspect of the present disclosure is to provide a device and method capable of detecting the insertion direction of a SIM card regardless of the type of the SIM card inserted into the SIM card socket unit of the terminal.

"In accordance with the above-described aspects of the present disclosure, there is provided a device for detecting the insertion direction of a SIM card in a terminal. The device includes a SIM card socket unit including a detection terminal that is disposed at a position to be contacted with a GND terminal of the SIM card, and when the SIM card is inserted, outputs a voltage received from the GND terminal of the SIM card, and a controller. The SIM card socket unit is configured to transmit the voltage output from the detection terminal to a controller as a SIM card insertion direction detection signal. In addition, the controller configured to determine if the SIM card is inserted in a reversed insertion based on the SIM card direction detection signal, and inform the user that the SIM card is inserted in a reversed direction upon determining as reversed insertion.

"In addition, there is also provided a method for detecting the insertion direction of a SIM card in a terminal. The method includes receiving a voltage from a GND terminal of the SIM card through a detection terminal of a SIM card socket unit when the detection terminal of the SIM card socket unit comes into contact with the GND terminal of the SIM card as the SIM card is inserted into the SIM card socket unit in the terminal, producing a SIM card insertion direction detection signal according to the received voltage from the detection terminal, and informing the user that the SIM card is inserted in a reversed direction when the SIM card insertion direction detection signal indicates reversed insertion.

"According to the device and method for detecting the insertion direction of a SIM card in a terminal, a reversed insertion of a SIM card with a symmetrical structure may be detected, and the user may be informed of the reversed insertion of the SIM card. In addition, since the user may be informed of the reason why the SIM card inserted into a SIM card socket unit of a terminal is not recognized, the user may be aware whether the SIM card is not recognized due to a failure of the SIM card or due to the reversed insertion of the SIM card.

"Before undertaking the DETAILED DESCRIPTION OF THE DISCLOSURE below, it may be advantageous to set forth definitions of certain words and phrases used throughout this patent document: the terms 'include' and 'comprise,' as well as derivatives thereof, mean inclusion without limitation; the term 'or,' is inclusive, meaning and/or; the phrases 'associated with' and 'associated therewith,' as well as derivatives thereof, may mean to include, be included within, interconnect with, contain, be contained within, connect to or with, couple to or with, be communicable with, cooperate with, interleave, juxtapose, be proximate to, be bound to or with, have, have a property of, or the like; and the term 'controller' means any device, system or part thereof that controls at least one operation, such a device may be implemented in hardware, firmware or software, or some combination of at least two of the same. It should be noted that the functionality associated with any particular controller may be centralized or distributed, whether locally or remotely. Definitions for certain words and phrases are provided throughout this patent document, those of ordinary skill in the art should understand that in many, if not most instances, such definitions apply to prior, as well as future uses of such defined words and phrases.
