    Abstract: The present invention may include an electronic device comprising: a communication module for supporting first short-range wireless communication and second short-range wireless communication; and a processor which is functionally connected to the communication module, wherein the processor is configured to: establish a connection to a first external device over at least one channel in a band through the communication module, using the first short-range wireless communication; while the connection to the first external device is established, identify a request for performing the second short-range wireless communication with a second external device; and connect the second external device to the first external device or an external communication server over the at least one channel in the band, using the second short-range wireless communication, in response to the request. However, the present invention is not limited to the above-described embodiment, and may include other embodiments.

    Abstract: In a method of operating a storage device including a plurality of storage regions, a first request is received. The first request is for a cryptographic erasure with respect to a first storage region. During a first time interval, a first encryption key corresponding to the first storage region is changed based on the first request. A second request is received. In response to receiving the second request within the first time interval, a region access signal is outputted. In response to determining, based on the region access signal, that the second request is associated with the first storage region, an execution of the second request is held. In response to determining, based on the region access signal, that the second request is associated with a second storage region among the plurality of storage regions, the second request is executed.

    Abstract: A diffusion lens includes a first lens surface having a concave curved shape such that light generated from a light source is incident on the first lens surface, a second lens surface having a convex curved shape such that part of the light incident on the first lens surface is output from the second lens surface, a side surface extending from a periphery of the second lens surface in a vertical direction of the diffusion lens such that part of the rest of the light incident on the first lens surface is output from the side surface, and a bottom surface extending from a periphery of the first lens surface in a horizontal direction of the diffusion lens to meet a periphery of the side surface. Rates of change of the first lens surface and the second lens surface have the same sign, and a pattern in which arbitrary shapes are irregularly disposed or a pattern in which specified shapes are regularly or irregularly disposed is formed on the side surface and the bottom surface to diffuse the light passing through the side surface and diffuse the light reflected by the bottom surface. Besides, it may be permissible to prepare various other embodiments speculated through the specification.
