  • Publication number: 20220317010
    Abstract: A system for determining a filter for evaluating a dissolution quality of a binder solution for a secondary battery electrode according to the present technology includes: a pressure container which accommodates a binder solution; a pressure medium supply source which supplies pressure medium of a predetermined pressure to the pressure container; a filter which is connected to the pressure container by a pipe; a flow rate measuring unit which measures a flow rate of the binder solution filtered by the filter; and a determination unit which measures a time point when a flow rate reaches a specific value predetermined in consideration of an initial flow rate by repeating measurement of the flow rate using each filter having a different pore size, and determines a filter having a filter size in an optimal pore size range based on the time point.

  • Patent number: 11275479
    Abstract: Disclosed is an electronic device. The electronic device includes an impedance measuring unit including electrodes, that applies a first measurement signal of a first frequency to a user, obtains first biometric impedance data, based on first electrodes among the electrodes, and obtains second biometric impedance data, based on second electrodes among the electrodes, and a signal processor that extracts first feature data of the user, based on the first biometric impedance data and the second biometric impedance data. The first feature data may be based on a ratio between a value of the first biometric impedance data and a value of the second biometric impedance data.

  • Publication number: 20210334348
    Abstract: A biometric authentication apparatus is provided. The biometric authentication apparatus includes one or more converters that convert a transmit signal of an electrical signal into a vibration signal of a mechanical signal and transmit the vibration signal vibrating within a set frequency range to a user, one or more sensor that receive a biometric signal corresponding to the vibration signal from the user and convert the biometric signal into a receive signal of an electrical signal, an authentication module that extracts anatomical feature information of the user from the receive signal and determines whether the user is a registered user based on the anatomical feature information, and a memory that stores a database for the registered user. The biometric signal is a frequency-based signal modified to include the anatomical feature information while the vibration signal passes through at least a portion of the body of the user.

  • Publication number: 20200159902
    Abstract: Provided is a personal authentication device based on an auditory brainstem response signal. The personal authentication device includes a signal generator, a signal acquirer, and a signal processor. The signal generator may output an auditory stimulus to an ear of a user, using a sound generator. The signal acquirer may acquire a first reference potential corresponding to a first interval, from a first electrode in close contact with the other ear of the user, and acquire a first evoked potential corresponding to the first interval from a second electrode in close contact with the ear, based on the first reference potential. The signal processor may generate a first auditory brainstem response signal, based on the first reference potential and the first evoked potential, generate authentication data for the user from the first auditory brainstem response signal, and compare the authentication data with registration data to authenticate the user.
