Abstract: A smart key box includes a key holding element, a housing, a power assembly, sensing units, an authentication module, and a control module. The housing is configured to contain the key holding element. The power assembly is disposed in the housing and configured to drive the key holding element to leave the housing or enter the housing along an access direction. The sensing units are disposed in the housing. When the key holding element leaves the housing or enters the housing, the key holding element is configured to trigger at least one of the sensing units. The authentication module is disposed at the housing. The control module is disposed in the housing and electrically connected with the power assembly, the sensing units, and the authentication module, and is configured to control the power assembly according to the at least one of the sensing units which is triggered.

Abstract: An electronic device, a method and a non-transitory computer-readable medium of messaging are disclosed herein. The electronic device includes at least one processor, a touch-sensitive module, a display module and a non-transitory computer-readable medium. The non-transitory computer-readable medium includes one or more sequences of instructions to be executed by the processor for performing a messaging method. The messaging method includes the following steps: sensing a touch corresponding to a first contact icon displayed on the display module; counting a time duration of the touch; recording a message when the time duration exceeds a first predetermined time period; and sending the message according to contact information corresponding to the first contact icon.

Abstract: A portable electronic device is provided, including a main body, a C-shaped member, and a hinge module, wherein the main body includes a display surface and the C-shaped member includes an opening. The hinge module pivotally connects the main body with the C-shaped member. When the main body is situated in a first position, the main body covers the opening. When the main body rotates from the first position around an axis to a second position relative to the C-shaped member via the hinge module, the main body is away from the opening. An acute angle is formed between the axis and the display surface.

Abstract: An electronic device and a display switching method thereof are disclosed herein. The electronic device includes at least one processor, a display module, a touch-sensitive module and a non-transitory computer-readable medium. The non-transitory computer-readable medium includes one or more sequences of instructions to be executed by the processor for performing the display switching method. The display switching method includes the following steps: sensing a touch by the touch-sensitive module; counting a time duration of the touch; displaying a list of at least one contact icon by the display module when the time duration of the touch exceeds a first predetermined time period, wherein the list is scrollable for selecting a target icon of the icons, and each icon corresponds to a contact or a group of contacts; and displaying a target chat window corresponding to the target icon.
