The data storage device can be unlocked by biometric authentication to enable a host device to access user data in the storage medium.

Abstract: This disclosure relates to data storage device (DSD) hardware and, more specifically, to systems and methods for encrypting data stored on a DSD. A DSD comprises a non-volatile storage medium to store multiple file system data objects using block addressing. The multiple file system data objects are addressable by respective ranges of blocks. A device controller is integrated with the DSD and comprises hardware circuitry configured to encrypt data to be stored on the storage medium and decrypt data stored on the storage medium based on different cryptographic keys, and to use each of the different cryptographic keys for one of the ranges of blocks addressing a respective file system data object. The decryption part of the hardware circuitry can be deactivated so that the data can be read in encrypted form.

Abstract: This disclosure a smart card device that provides a bus interface, such as a USB-C bus interface, printed on a portion of a PCB that forms a base layer of the smart card device. The smart card device can provide the bus interface without having to mount a traditional socket. By leveraging the portion of the PCB to provide a printed bus interface and excluding the traditional socket, the bus interface can be easily manufactured using well-known PCB manufacturing techniques while significantly reducing manufacturing costs. Furthermore, the smart card device can have a thickness that conforms to known card form factor standards, enabling the smart device to fit within a standard wallet. To enhance durability of the portion of the PCB from wear-and-tear, a metal core can be added to the PCB as an additional layer. The portion may also be reinforced with edge plating.

Abstract: This disclosure relates to data storage device (DSD) hardware and, more specifically, to systems and methods for encrypting data stored on a DSD. A DSD comprises a non-volatile storage medium to store multiple file system data objects using block addressing. A device controller is integrated with the DSD and comprises hardware circuitry configured to encrypt data to be stored on the storage medium. The controller receives a request for an encrypted file system data object from a host computer system, identifies one of the ranges of blocks where the requested encrypted file system data object is stored on the storage medium, and sends the file system data object stored in the identified range of blocks to the host computer system in encrypted form as stored on the storage medium.

Abstract: A bed includes a base, an upper frame, and a plurality of walls extending upwardly from the base to the upper frame. One of the frame members is a movable frame member that is movable relative to another of the frame members in order to adjust a height of a portion of the rim formed by the movable frame member relative to the base.
