  • Patent number: 11443060
    Abstract: When a user approaches or accesses a device, the device attempts to recognize the user. A multi-user note management system takes different actions based on whether the user is recognized as the owner of the device, is recognized as a known user of the device, or is determined to be an unknown user of the device. If the user is recognized as the owner or a known user, the system receives user input and stores the user input as a note. If the user is an unknown user, the system does not allow the user to leave a note at the device, or receives user input and captures an image of the user, and stores the user input as a note associated with the captured image. When the owner of the device unlocks the device after a note has been left, the system displays or otherwise presents the notes.

  • Patent number: 11373439
    Abstract: In order to authenticate a user of an electronic device, an image of the user's fingerprint is captured. Before feature information is extracted, the fingerprint image is enhanced via localized normalization thereby increasing contrast within the fingerprint image. Thereafter, feature information, such as key point data, is extracted from the image and compared to a predefined template to determine whether the feature information matches the template. If so, the user is authenticated. By enhancing the quality of the fingerprint image through localized normalization, the reliability of the matching operation is significantly enhanced. In addition, using key point comparisons for assessing similarity between the feature information and the template helps to address inconsistencies relating to finger rotation, scale, and translation during capture.

Embodiments may display the radiomic score, or generate a personalized treatment plan based on the radiomic score.

  • Patent number: 11347277
    Abstract: The present disclosure relates to a display assembly, a method of using the display assembly, and an electronic device, which uses the display assembly, for detecting an identification surface of an object (e.g., a fingerprint) using a detection signal, which penetrates the object and reflects a target signal representative of at least part of the identification surface (e.g., the orthographic projection of the fingerprint) onto an identification area on a display. A signal receiver (i.e., comprising a signal receiver) then detects the target signal. The target signal can be used by a processor to further authenticate whether it corresponds to an authorized user. The display assembly includes a display having an identification area, a signal transmitter (i.e., comprising a signal transmitter) configured to generate a detection signal when an object is within a preset distance of the identification area, and a signal receiver configured to detect the target signal.

  • Patent number: 11340716
    Abstract: Touch-based input devices, such as a stylus, can receive tactile input from a user. The tactile input functions can be performed by a touch sensor, such as a capacitive sensing device. A touch sensor can be integrated into a stylus in a low profile form. Tactile input can be received at the user's natural grip location. Furthermore, the stylus can effectively distinguish between tactile inputs from a user and disregard sustained tactile inputs that are provided while the user simply holds the stylus at the user's natural grip location.

  • Patent number: 11335116
    Abstract: The present invention relates to an apparatus and method for identifying a fake fingerprint by using impedance, which enables identification of a fingerprint or fake fingerprint by measuring an impedance value of a fake fingerprint made of silicon or gelatin. In the present invention, a fingerprint recognition module identifies, through a driver IC, an impedance value of an ultrasonic wave reflected from a finger and identifies a fake fingerprint on the basis of a changed impedance value, and determines a fake fingerprint by measuring an impedance value in an ultrasonic wave which is emitted from the fingerprint recognition module, collides with a fake fingerprint, and is then reflected therefrom.

  • Patent number: 11328165
    Abstract: In a method for performing operating a fingerprint sensor, an image of a fingerprint of a finger is captured at a fingerprint sensor. A force applied by the finger at the fingerprint sensor is determined, where the force is a measure of pressure applied by the finger on the fingerprint sensor during capture of the image. The force is compared to a pressure threshold. Provided the force satisfies a pressure threshold, a spoof detection operation is performed to determine whether the finger is a real finger. Provided the force does not satisfy the pressure threshold, fingerprint authentication using the image of the fingerprint is performed without performing the spoof detection operation.

  • Patent number: 11328531
    Abstract: An apparatus for direct optical recording of skin prints has a display below the placement surface and a light guide layer below the display. The light guide layer has light in-coupling at a narrow side and light out-coupling structures in the surface. By means of angles ? of the light out-coupling structures and differences in the refractive indices of the neighboring layers, a directed coupling out of light occurs in the direction of the placement surface causing a total internal reflection at the placement surface. The display has a transparency of at least 1% of the coupled out light. A first and second adhesion layers are between the display and the light guide layer and between the light guide layer and the sensor layer. The refractive indices of the adhesion layers are at least 1% to 30% lower than those of light guide layer, the display and the sensor layer.
