Abstract: An electronic device is disclosed. An electronic device may include: a foldable housing including a hinge, a first housing connected to the hinge and including a first surface oriented in a first direction and a second surface oriented in a second direction opposite the first direction, a second housing connected to the hinge and including a third surface oriented in a third direction and a fourth surface oriented in a fourth direction opposite the third direction, wherein the second housing is configured to be folded on the first housing about the hinge, and side surfaces surrounding at least a part of a space between the first surface and the second surface and at least a part of a space between the third surface and the fourth surface; and a display having ductility and extending from the first surface to the third surface to configure the first surface and the third surface, wherein the foldable housing is disposed along an edge of the display and includes bezels extending from respective side surfaces to an active area of the display, and wherein the bezels include, in an area configuring the first surface and the third surface of the foldable housing, extensions spaced apart from edge portions of the display, and support portions disposed between the edge of the display and the extensions to be in contact with the edge portions of the display.

Abstract: A device for measuring a reflection coefficient of an antenna by using a radio frequency (RF) feedback signal provided by a coupler based on an RF transmission signal provided to the antenna includes a feedback circuit configured to generate a baseband feedback signal by down-converting and filtering the RF feedback signal, and a signal processing device configured to control the down-converting, based on a target frequency band, process a baseband transmission signal and the baseband feedback signal to have the target frequency band, and calculate a reflection coefficient of the antenna corresponding to the target frequency band. The RF transmission signal is generated from the baseband transmission signal.

Abstract: The method and apparatus support signature-based application management that examines credibility of an application to be installed or executed and controls installation and execution accordingly. The application management method for a user device includes: receiving user input for installing an application; comparing signature information of the application with an authentication list stored in a signature information storage; preventing, when the signature information is present in a blacklist of the authentication list, installation of the application; initiating, when the signature information is present in a whitelist of the authentication list, installation of the application; and selectively performing, when the signature information is not present in either the blacklist or the whitelist, installation of the application according to user consent.

Abstract translation: 该方法和装置支持基于签名的应用程序管理，检查要安装或执行的应用程序的可信性，并相应地控制安装和执行。 用户设备的应用管理方法包括：接收用于安装应用的用户输入; 将应用的签名信息与存储在签名信息存储器中的认证列表进行比较; 当签名信息存在于认证列表的黑名单中时，防止应用的安装; 当签名信息存在于认证列表的白名单中时启动应用的安装; 并且当黑名单或白名单中的签名信息不存在时，根据用户同意选择性地执行应用的安装。
