Abstract:
A Dynamic Voltage and Frequency Scaling (DVFS) method, comprising of a scheduling execution of DVFS to adjust frequency or voltage of a target device at a first scheduled time; monitoring operating frequency of the target device; and selectively deferring execution of DVFS at a later scheduled time based on the operating frequency of the target device; wherein execution of DVFS at a next scheduled time is deferred when the operating frequency of the target device is below a given minimum frequency.
Abstract:
A wearable mobile device and a method of detecting a biosignal with a wearable mobile device are provided. A method of detecting a biosignal with a wearable mobile device involves determining whether a wearable mobile device is closely attached to a user; and providing a biosignal-based service in response to the wearable mobile device being determined to be closely attached to the user.
Abstract:
An electronic device according to an embodiment of the present invention comprises a first conductive plate; and a second conductive plate which extends from the first conductive plate at a first angle to the first conductive plate, wherein the first conductive plate and the second conductive plate comprise a conductive member which forms a cavity opened in a first direction perpendicular to the first conductive plate; a first radiation unit which is disposed apart from the first conductive plate by a first distance in a first direction; a second radiation unit which is disposed apart from the first conductive plate by a second distance in a second direction opposite to the first direction; at least one wireless communication circuit which feeds electricity to the first radiation unit and the second radiation unit; and a processor which is electrically connected with the wireless communication circuit, the processor can be set to cause the wireless communication circuit to receive a signal of a first frequency having a directivity in the first direction on the basis of the cavity formed by the first radiation unit and the conductive member, and to receive a second frequency signal on the basis of the coupling of the second radiation unit and at least a portion of the conductive member. In addition, various embodiments understood from the specification may be possible.
