Abstract:
A dietary habit management apparatus and method are provided. The dietary habit management apparatus includes a bio-signal acquirer configured to acquire a bio-signal of a user, and a processor configured to obtain a total peripheral resistance (TPR) reflected index, from the bio-signal that is acquired by the bio-signal acquirer, and determine whether the user has eaten food, based on the TPR reflected index.
Abstract:
A wearable device includes a first sensor configured to detect a first biosignal generated in response to a gesture performed by a user, and a second sensor configured to detect a second biosignal of the user. The device further includes a memory configured to store, with respect to at least one user, information of the first biosignal and the second biosignal, and a processor configured to initiate user authentication based on a result of determining whether the detected first biosignal corresponds to the stored information, and authenticate the user by comparing the detected second biosignal to the stored information.
Abstract:
A wireless power transmission apparatus for high efficiency energy charging, includes a resonator configured to transmit power, and a power supply unit configured to supply power to the resonator. The apparatus further includes a first switching unit configured to connect the resonator to the power supply unit, and disconnect the resonator from the power supply unit, and a controller configured to control the first switching unit based on an amount of current flowing into the resonator.
Abstract:
An apparatus and a method for wirelessly receiving and transmitting energy are provided. A wireless energy receiving apparatus in a terminal configured to wirelessly receive energy through mutual resonance between a resonator of an energy supply apparatus configured to supply the energy and a resonator of the terminal, includes an energy measuring unit configured to measure an amount of energy stored in the terminal. The wireless energy receiving apparatus further includes a control unit configured to change a state of the resonator of the terminal from a non-resonant state to a resonant state when the measured amount of energy is less than or equal to a predetermined threshold.
Abstract:
A method and apparatus provide for stable signal demodulation in a communication system. The method and apparatus includes including detecting an erroneous demodulation value based on backward-demodulation of received signals, using a difference between a received signal to be demodulated and a preceding signal of the received signals and correcting the error demodulation value. Alternatively, backward-demodulation is used to confirm received signals.
Abstract:
An apparatus and a method for processing a signal, and for estimating a point corresponding to a maximum slope from an envelope of an input signal, are provided. A signal processing apparatus includes an envelope detecting unit configured to detect an envelope of an input signal. The signal processing apparatus further includes a correcting unit configured to correct slopes, each of the slopes being between respective points of the envelope, based on information on a clipping interval of the envelope. The signal processing apparatus further includes an estimating unit configured to estimate a point, of the envelope, in which a corrected slope, among the corrected slopes, includes a maximum value.
