Abstract: A method is to be implemented by a computing device that stores a risk assessment model, and includes steps of: obtaining an entry of target physiological data and target magnetic resonance imaging (MRI) images of a brain of a subject with mild cognition impairment (MCI); obtaining, based on the target MRI images, voxel values respectively of primitive voxels that are related to grey matter of the brain of the subject; selecting, from among the primitive voxels, any primitive voxel satisfying a filtering criterion as a selected voxel; calculating an average of the voxel value(s) respectively of the selected voxel(s) to obtain an average target voxel value; and obtaining a probability of the subject developing Alzheimer's disease within a predetermined time period by feeding the average target voxel value and the entry of target physiological data into the risk assessment model.

Abstract: Systems and methods for storing and recovering data for a device are described. In one embodiment, factory generated calibration data can be generated, sealed and restored securely even if two sensors in two different devices, such as a first ambient light sensor and a second ambient light sensor have the same sensor identifier. In one embodiment, a device transmits a database key to cause storage or recovery of the calibration data, and the database key includes a sensor identifier and a public cryptographic key of the device.

Abstract: In some examples, a method comprises determining, at an electronic device having a first component of a first component type, a unique identifier associated with the first component. In some examples, in accordance with a determination that the unique identifier does not match the expected identifier of the component of the first component type in the electronic device, determining that the first component associated with the unique identifier satisfies one or more eligibility criteria. In some examples, in accordance with the determination that the first component associated with the unique identifier satisfies the one or more eligibility criteria, authenticating an association of the first component with the electronic device, including updating an installation counter associated with the first component, and updating the expected identifier for the component of the first type based on the unique identifier of the first component.

Abstract: A mobile hard disk, having a shield, a disk body having a front surface, an electric circuit board electrically connected to the disk body. The electric circuit board is parallel to and contacts with the front surface of the shield, wherein the electric circuit board and the disk body are both received in the shield. As the electric circuit board is parallel to and contacts with the front surface of the disk body, so the electric circuit board takes a little space of the shield, and the volume of the mobile hard disk is smaller than the traditional one.
