Abstract:
A quasi-isotropic antenna includes: a feeder; a loop antenna configured to radiate a first radio wave based on a feeding from the feeder; and a dipole antenna adjacent to the loop antenna, and configured to radiate a second radio wave by resonating based on a resonant-coupling with the loop antenna, wherein a radiation pattern of the first radio wave is orthogonal to a radiation pattern of the second radio wave.
Abstract:
Disclosed is a near-field communication (NFC) system that includes an NFC supporting apparatus. The NFC supporting apparatus includes a dual coil and a first switch. The dual coil includes an NFC band coil and a radio frequency (RF) band coil. An RF amplitude modulation signal is generated at the RF band coil in response to a transmission from an implantable device. The first switch is configured to switch the NFC band coil based on the RF amplitude modulation signal. The NFC band coil is configured to generate an NFC amplitude modulation signal at an NFC band coil of an NFC reader in response to the first switch.
Abstract:
An exercise feedback provision apparatus includes an acquirer configured to acquire exercise intensity information including either one or both of user biometric information and user movement information, and a controller configured to verify whether the exercise intensity information is in a predetermined range, and generate a control signal based on a result of the verifying. The apparatus further includes a feedback provider configured to output a tactile feedback based on a pattern corresponding to the control signal.
Abstract:
A method of processing a biosignal includes estimating a time period from a time-domain biosignal, converting a biosignal corresponding to a time interval based on the time period to a frequency-domain signal, performing signal processing to remove a distortion component from the frequency-domain signal, and converting a processed frequency-domain signal obtained through the signal processing to a time-domain signal.
Abstract:
A method of measuring a time difference between detection times includes receiving, from a first sensor, first information associated with a first detection time at which a first biosignal is detected, receiving, from a second sensor, second information associated with a second detection time at which a second biosignal is detected, and measuring a time difference between the first and the second detection times based on the first information and the second information.
