Abstract:
A signal processing method, a signal filtering apparatus, and a signal processing apparatus are provided. An input signal may be input into a filter having a passband, a superfluous signal of the passband may be output from the filter, and a target signal may be obtained by subtracting the superfluous signal from the input signal.
Abstract:
Provided are a devices, systems and methods for performing communication using wireless power. According to one general aspect, a communication device using wireless power may include: a controller configured to control mutual resonance between a target resonator and a source resonator; a demodulator configured to demodulate information transmitted from the source resonator based on an amount of energy received from the source resonator; and a modulator configured to modulate information based on the mutual resonance.
Abstract:
A method and apparatus are configured to recognize mobile terminals positioned within a coverage area for short range communication with a user-specific device, wherein each mobile terminal comprises identification information for the user-specific device. The method and the apparatus provide a customized service corresponding to at least one of the mobile terminals.
Abstract:
A wearable biosignal interface and operation method of the wearable biosignal interface is provided wherein the wearable biosignal interface may perceive a motion unintentionally performed by a user and ignore a biosignal obtained thereby and thus, improve accuracy of a bio-based determination of an intention of the user for operating a device.
Abstract:
A biosignal processing method involves estimating a baseline of a detected biosignal based on a comparison between the detected biosignal and a set value, and controlling a processing logic of the detected biosignal based on the estimated baseline.
Abstract:
A biosignal measuring method and apparatus are provided. The biosignal measuring method includes verifying whether a measured biosignal is in a range, and controlling an operation of the biosignal measuring apparatus when the measured biosignal deviates from the range based on a result of the verifying.
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:
A presentation device and an method of operating the presentation device may quickly move to a desired area on a map by adjusting a level of an electromyographic (EMG) signal even though a range of a motion of an arm is limited when searching the map using a wearable mobile device. The presentation device includes a first sensor unit configured to contact a measurement target and to obtain an electromyographic (EMG) signal from the measurement target; and a display controller configured to control a field of view (FOV) window for displaying a map area based on the EMG signal.
Abstract:
Provided is a device for measuring a signal and a method of operating the same. The device may include electrodes attached to the device, and a control unit for determining the optimal pair of electrodes to be used for measuring the signal. Also, the device may include an output unit for measuring signals that are sensed by the electrodes.
Abstract:
A method of selecting an interface by a hub, includes searching for a device of the hub, and setting an optimal interface to communicate with the device. The method further includes transmitting data to the device through the optimal interface.
