Abstract: A wireless power transmitter capable of selecting a master wireless power receiver to visually provide, to a user, states-of-charge of wireless power receivers being charged includes a coil, a short-range communication module for communicating with a plurality of the wireless power receivers receiving power from the coil, and a processor communicatively coupled to the short-range communication module. The processor detects a first wireless power receiver which has an inclination or a tilt or takes a preset motion from among the plurality of wireless power receivers, identifies the first wireless power receiver as a master wireless power receiver indicating states-of-charge of the plurality of wireless power receivers, and transmits, to the first wireless power receiver, a signal informing that the first wireless power receiver is identified as the master wireless power receiver.

Abstract: A signal receiver includes a data sampler receiving a differential input signal having first and second input signals and determining bit values of the differential input signal based on first and second reference voltages, and a reference voltage generator performing a pre-tuning operation and a post-tuning operation to generate the reference voltages. The reference voltage generator performs the pre-tuning operation by generating first and second initial voltages and adjusting one of the initial voltages to generate third and fourth voltages. After the pre-tuning operation, the reference voltage generator performs the post-tuning operation by increasing or decreasing the third voltage to generate the first reference voltage and decreasing or increasing the fourth voltage to generate the second reference voltage based on a comparison result between the third voltage and the first input signal and a second comparison result between the fourth voltage and second input signal.

Abstract: An exercise assistance method of assisting user's exercise based on ground inclination, a wearable device and an electronic device for performing the same are provided. The exercise assistance method may include determining ground inclination in a direction in which a wearable device worn by the user moves based on sensor data, determining whether a ground surface in the direction in which the wearable device moves is downward inclination or upward inclination based on the ground inclination, when the ground surface is the downward inclination or the upward inclination, determining target exercise speed to achieve a target exercise amount of an exercise program performed by the wearable device based on the ground inclination, and adjusting at least one of current target exercise speed set to the exercise program and current exercise intensity set to the exercise program based on the determined target exercise speed.
