This abstract first appeared for US patent application 18703673 titled 'FALSE WAKEUP REDUCTION FOR FINGERPRINT SENSORS
Original Abstract Submitted
An apparatus () includes a fingerprint sensor () including a wakeup sensor portion () and a transmitter portion (). The wakeup sensor portion () may be configured to send an activation signal () to the transmitter portion () due to a contact indication, corresponding to contact with an outer surface of the apparatus () in the fingerprint sensor area that equals or exceeds a contact indication threshold. A control system () of the apparatus () may include: a fingerprint sensor control system portion () configured for controlling the transmitter portion () and for determining, based at least in part on fingerprint sensor data obtained from an object in contact with the outer surface of the apparatus () in the fingerprint sensor area, whether the object is a finger: a fingerprint image data processing control system portion (); and a wakeup reduction module () configured to control the contact indication threshold based, at least in part, on one or more time intervals between consecutive false wakeups.
