Abstract: Devices, methods and graphical user interfaces for manipulating user interfaces based on fingerprint sensor inputs are provided. While a display of an electronic device with a fingerprint sensor displays a first user interface, the device may detect movement of a fingerprint on the fingerprint sensor. In accordance with a determination that the movement of the fingerprint is in a first direction, the device allows navigating through the first user interface, and in accordance with a determination that the movement of the fingerprint is in a second direction different from the first direction, the device allows displaying a second user interface different from the first user interface on the display.

Abstract: A method may include intravenously directing first bubbles into a patient's venous circulatory system and to a right side of the patient's heart. The first bubbles may have sizes that fall within a first range. The method may further include monitoring the patient's heart, with ultrasound imaging, to detect presence of the first bubbles on a left side of the patient's heart. Upon detecting the first bubbles on the left side of the patient's heart, the method may further include intravenously directing second bubbles into the patient's venous circulatory system and to the right side of the patient's heart. The second bubbles may have sizes that fall within a second range that is different than the first range. Upon detecting the second bubbles on the left side of the patient's heart, the method may further include initiating treatment to minimize risk of stroke in the patient.
