  • Publication number: 20200395377
    Abstract: A semiconductor memory device includes a third insulating pattern and a first insulating pattern on a substrate, the third insulating pattern and the first insulating pattern being spaced apart from each other in a first direction that is perpendicular to the substrate such that a bottom surface of the third insulating pattern and a top surface of the first insulating pattern face each other, a gate electrode between the bottom surface of the third insulating pattern and the top surface of the first insulating pattern, and including a first side extending between the bottom surface of the third insulating pattern and the top surface of the first insulating pattern, and a second insulating pattern that protrudes from the first side of the gate electrode by a second width in a second direction, the second direction being different from the first direction.

  • 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.

  • Publication number: 20200019690
    Abstract: Provided is a biometric authentication system for authenticating a user. The biometric authentication system includes an input function generator generating an input function for determining a first time interval in a transmission interval in which an input signal is transmitted to a user, a second time interval in the transmission interval, a first frequency of the first time interval, and a second frequency of the second time interval, an input signal generator transmitting the input signal having the first frequency during the first time interval and the second frequency during the second time interval, to the user, based on the input function, and an authenticator acquiring a biometric signal generated in response to the input signal from the user and determining whether the user is authenticated based on the biometric signal.

  • Publication number: 20150050722
    Abstract: Aspects of the invention include cell culture systems that include a cell culture plate operatively coupled to a plenum device. The plenum device includes a base component, one or more wall components configured to define a bounded volume, and one or more strain platens that are configured to support the cell culture plate when the cell culture plate is operatively coupled to the plenum device. In some instances, the plenum device includes a pressure modulator configured to provide a substantially uniform pressure in the bounded volume upon application of an external pressure source via an internal side opening in a wall component. Aspects of the invention further include system components and kits thereof, as well as methods of using the systems, e.g., in cell culture applications, which may include, e.g., candidate agent screening applications.
