Abstract: An optical system affixed to an electronic apparatus is provided, including a first optical module, a second optical module, and a third optical module. The first optical module is configured to adjust the moving direction of a first light from a first moving direction to a second moving direction, wherein the first moving direction is not parallel to the second moving direction. The second optical module is configured to receive the first light moving in the second moving direction. The first light reaches the third optical module via the first optical module and the second optical module in sequence. The third optical module includes a first photoelectric converter configured to transform the first light into a first image signal.

Abstract: A method for predicting clinical severity of a neurological disorder includes steps of: a) identifying, according to a magnetic resonance imaging (MRI) image of a brain, brain image regions each of which contains a respective portion of diffusion index values of a diffusion index, which results from image processing performed on the MRI image; b) for one of the brain image regions, calculating a characteristic parameter based on the respective portion of the diffusion index values; and c) calculating a severity score that represents the clinical severity of the neurological disorder of the brain based on the characteristic parameter of the one of the brain image regions via a prediction model associated with the neurological disorder.

Abstract: A method for performing adaptive locking range management, an associated data storage device and a controller thereof are provided. The method may include: receiving a security command from outside of the data storage device, wherein the security command is related to changing an old locking range into a new locking range; obtaining a start Logical Block Address (LBA) and a length value of the new locking range according to the security command; determining whether the start LBA of the new locking range is less than an end LBA of the old locking range, and determining whether an end LBA of the new locking range is greater than a start LBA of the old locking range; and in response to both determination results being true, performing data trimming on any respective non-overlapped portions of the new locking range and the old locking range.

Abstract: A security extension design for non-volatile memory is shown. There is an in-system program loaded into the non-volatile memory. A memory controller downloads the in-system program to a data register to provide base firmware code, a function pointer structure and security firmware code on the data register. The memory controller executes the base firmware code, and security functions of the security firmware code are called by the base firmware code through information recorded in the function pointer structure and thereby the memory controller is switched to operate the non-volatile memory at a higher security level. The security firmware code uses an application programming interface (API) and is compatible with multiple projects.

Abstract: A security mechanism of non-volatile memory. The controller encrypts a privilege password and stores the encrypted privilege password in a non-volatile memory. Before being stored in the non-volatile memory, a key used to encrypt data for data storage on the non-volatile memory may be encrypted using a Key Encryption Key (KEK). The KEK may be used in the encryption of the privilege password, so that the non-volatile memory stores the privilege password and the KEK in ciphertext. In response to the matched privilege password, the KEK is obtained to decrypt the encrypted key for decryption of (user) data.
