Abstract: An example method is performed at a device with a display and a biometric sensor. While the device is in a locked state, the method includes displaying a log-in user interface that is associated with logging in to a first and second user account. While displaying the log-in user interface, the method includes, receiving biometric information, and in response to receiving the biometric information: when the biometric information is consistent with biometric information for the first user account and the first user account does not have an active session, displaying a prompt to input a log-in credential for the first user account; and when the biometric information is consistent with biometric information for the second user account and the second user account does not have an active session on the device, displaying a prompt to input a log-in credential for the second user account.

Abstract: A method for fabricating an Invar tool includes the step of superplastically forming an Invar facesheet for the tool. A tool header is provided, and the Invar facesheet is then formed with an SPF diaphragm driver to match the predetermined contour of the tool header. The Invar facesheet is then welded to the tool header. Forming the Invar facesheet is achieved by positioning the Invar facesheet between a superplastically formable diaphragm and a die having the predetermined contour. The diaphragm is heated to a predetermined superplastic temperature, and a predetermined pressure is applied to the diaphragm. Application of the predetermined pressure allows the diaphragm to cause the Invar facesheet to form against the predetermined contour of the die. Superplastically forming the Invar facesheet results in a negligible amount of excess scrap, reduces material costs, and reduces labor costs.
