An apparatus may include an ultrasonic sensor system having a first layer stack and a second layer stack. The first layer stack may include a first ultrasonic transmitter and the second layer stack may include a second ultrasonic transmitter. The first layer stack and/or the second layer stack may include an ultrasonic receiver. A frequency splitting layer may reside between the first layer stack and the second layer stack.

A sensing device of an embodiment includes: a first sensor that acquires three-dimensional shape information on a surface of an object to be sensed; and a second sensor that acquires texture information on the surface or a vicinity of the surface of the object to be sensed at a position having a predetermined positional relation with an information acquisition position in the object to be sensed of the first sensor.

A device for capturing a biometric print of a user, the user compartment including a frontal opening designed for the passage of part of a hand into said user compartment and a lateral opening allowing the passage of the thumb of the user's hand, the lateral opening extending as far as the frontal opening to form a continuous open space, the lateral opening being delimited in a direction of insertion of the user's hand into the user compartment by a user hand positioning stop.

Disclosed is a system for preventing drunk driving of a vehicle, the system including: an input unit through which a transfer intention to transfer a control privilege of a vehicle from a registered driver to a passenger is input; a sobriety determination unit configured to determine a current driver's inebriation state through a breathalyzer provided in the vehicle when the transfer intention is input through the input unit; a driver verification unit configured to identify personal information of the current driver seated on a driver's seat; and a control unit configured to transfer the control privilege of the vehicle to the passenger when the passenger is measured as being able to drive by the sobriety determination unit and the passenger and the current driver are identified to be the same by the driver verification unit.

This fingerprint registration method by a user terminal device includes: capturing an image of a fingertip by a camera provided to the user terminal device; generating and displaying an enlarged image obtained by enlarging a fingertip image that includes the captured fingertip; receiving a user operation whether or not the fingertip image is to be registered for fingerprint authentication on the basis of the enlarged image; and transmitting, to an external server as fingerprint data, the fingertip image on which registration operation has been performed through the user operation.

A contactless type optical device includes an image photographing module configured to photograph a subject, the image photographing module including a photographing lens forming an image of light that is scattered from the subject and is incident on the photographing lens; an illuminator configured to radiate illumination light, the illuminator being disposed within a predetermined distance from the image photographing module; a first lens configured to reduce an incidence angle of the illumination light traveling from the illuminator; and a second lens having a first surface to which the illumination light passing through the first lens is incident to be transmitted, and a second surface to which the subject's scattered light scattered from the subject is incident to be transmitted. The photographing lens is disposed such that the subject's scattered light passing through the second lens is incident on the photographing lens.

In the fingerprint identification system according to the present disclosure, the fingerprint sensor collects multiple frames of fingerprint images sliding-inputted by a user, the judging unit determines whether, among the multiple frames of fingerprint images, there is a first overlap region between a current frame of fingerprint images and a previous frame of fingerprint images; if yes, the judging unit removes the first overlap region from the current frame of fingerprint images and superposes the previous frame of fingerprint images with the current frame of fingerprint images to form a superposed fingerprint image; the judging unit completes judgment of all the multiple frames of fingerprint images to obtain a template fingerprint image; the processing unit saves characteristic points of the complete template fingerprint image. The fingerprint sensor collects a to-be-identified fingerprint image pressing-inputted by the user, and the processing unit determines whether the characteristic points of the to-be-identified fingerprint image match with the characteristic points of the template fingerprint image. When establishing template fingerprint database, the fingerprint identification system collects the fingerprint sliding-inputted by the user and the to-be-identified fingerprint pressing-inputted by the user in the subsequent matching process. Therefore, the input and identification efficiency is much higher than that of existing methods. The present disclosure also provides a fingerprint identification method and an electric equipment.
