US10984882B2 Run-time memory device failure detection enhancement
The subject technology provides implementations, which may be included as part of firmware of the flash memory device, that will not solely rely on a flash controller interpreted status but includes additional checks to the returned flash status byte.

In at least one embodiment, the interactive sign language recognition system performs automatic sign language recognition to determine one or more gestures in the video signal.
US10984225B1 Masked face recognition
Embodiments of the present disclosure provide systems and methods for recognizing a masked face. According to the present disclosure, the disclosed systems and methods include features that provide augmentation of existing face recognition databases, real-time mask detection, and real-time masked face recognition. In embodiments, masked face recognition includes a multi-layered approach, which includes finding matching simulated masked faces in the database that match the masked face being analyzed, comparing the unmasked portion of the masked face to stored unmasked faces in a database to identify any matches, and executing face restoration algorithms in which the masked portion is reconstructed to generate an unmasked representation which may then be matched against unmasked faces in the database.
US10984220B2 Method and a device for verifying liveness of a finger
A method for verifying liveness of a finger of a user by capturing a first fingerprint sample from the finger placed on a display by using a first sensor placed under the display. The method may involve transmitting light, by using a first light transmitting display area of the display, towards a first area of the finger. The first light transmitting display area may be smaller than a first sensor area. The first sensor may capture reflected light from the finger. The reflected light may be transmitted through the display. A first feature of the first fingerprint sample may be identified by using the reflected light. The first feature may include scattered light from the finger. The light transmitted from the display may include a first light component with a first wavelength from a first area of the display.
US10984218B2 Post verification fingerprint image capture
The invention relates to a method of a fingerprint sensing system arranged in an electronic device of capturing fingerprint data of a user contacting a fingerprint sensor of the fingerprint sensing system, and a fingerprint sensing system performing the method.
