Abstract: An electronic device according to an embodiment includes: a first housing including a frame cover; a second housing coupled to the first housing and configured to be slidable relative to the first housing; a flexible display disposed on one surface of the second housing, and configured to slide into or out of the first housing by movement of the second housing; a motor disposed on the frame cover; a pinion gear coupled to the motor and configured to be rotatable by the motor; a rack gear disposed on an inner surface of the second housing, opposite to the one surface of the second housing, and is engaged with the pinion gear to be movable according to rotation of the pinion gear; and a battery disposed on a seating surface of the frame cover spaced apart from the motor, and configured to supply power to the motor, wherein the frame cover includes a plurality of first through holes penetrating the seating surface that is in contact with the battery.

Abstract: This application provides object recognition applicable to various scenarios such as security, a cloud technology, artificial intelligence, smart transportation, and assisted driving. The object recognition may be performed by: obtaining, by a recognition device, a distance between a to-be-recognized object and the recognition device; in response to the distance being not equal to a target distance between the to-be-recognized object and the recognition device, controlling, according to the distance, a wind pressure generator to adjust a wind pressure acting on the to-be-recognized object to cause the to-be-recognized object to move to a location having the target distance; and in response to the distance being equal to the target distance, recognizing the to-be-recognized object to obtain a recognition result. In the embodiments of this application, the wind pressure acting on the to-be-recognized object is determined according to the distance between the to-be-recognized object and the recognition device.

Abstract: According to an embodiment of the disclosure, a motor assembly may include a stator including a coil; a rotor accommodated inside the stator and configured to rotate; first and second housings coupled to first and second sides of the stator; an impeller disposed in a first direction of the first housing and configured to rotate together with the rotor by being coupled to one side of the rotor; a cover having an opening through which air is introduced by rotation of the impeller, and configured to protect the impeller; and a heat dissipation member surrounding at least a portion of an outer surface of the stator and configured to reduce heat generated in the motor assembly as the rotor rotates. Therefore, it is possible to minimize vibration caused by the rotation of the motor, thereby reduce noise, and lower heat generated inside the motor. Other various embodiments are possible.

Abstract: A social networking system obtains information describing one or more interactions performed by users of the social networking system with various applications. The information identifies users, applications, and interactions by users with applications. Based on the obtained information, the social networking system determines likelihoods of a selected user performing another type of interaction with each application in a set of applications. The set of applications are ranked based on the determined likelihoods, and one or more of the applications from the set are selected based on the ranking. Information describing the selected one or more applications is then provided to the selected user.
