摘要： A low-profile Universal-Serial-Bus (USB) device includes a PCBA in which all passive components and unpackaged IC chips are attached to a single side of a PCB opposite to the metal contacts. The IC chips include, for example, a USB controller chip and a flash memory chip, or a single-chip (combined USB controller/flash memory) chip. Multiple flash IC chips are optionally stacked to increase storage capacity. The IC chip(s) are attached to the PCB by wire bonding or other chip-on-board (COB) technique. The passive components are attached by conventional surface mount technology (SMT) techniques. A molded housing is then formed over the IC chips and passive components such that the device has a uniform thickness. The low-profile USB device is optionally used as a modular insert that is mounted onto a metal case to provide a USB assembly having a plug shell similar to a standard USB male connector.

摘要： A secure flash-card reader reads a user ID from a secure card and finds a matching entry with a hashed password in a user table on the reader. An encrypted key is received from a secure host that hashes and encrypts a password the user types into the host and the user's ID. A card decryption engine uses a random number to decrypt the encrypted key and recover the hashed password and user ID from the secure host, which is compared by a comparator to the hashed password and user ID from the user table. A mismatch causes an access controller to block access to encrypted data on the secure card. Flash data is transferred over a flash-serial buffer bus between flash-card controllers and a RAM buffer. An encryption engine on the flash-serial buffer bus encrypts and decrypts data and connects to a serial engine to the host.

摘要： In an electronic data storage device accessed by a host computer motherboard, a fingerprint sensor scans a fingerprint of a user of the electronic data storage device and generates fingerprint scan data. A processing unit activates an input/output interface circuit to store a data file and fingerprint reference data obtained by scanning a fingerprint of a person authorized to access the data file in a memory device having non-volatile memory, where the processing unit transmits the data file to the host computer motherboard upon verifying that the user of the electronic data storage device is authorized to access the data file stored in the memory device as a result of comparison between the fingerprint scan data from the fingerprint sensor and the fingerprint reference data. Other methods and apparatuses are also described.

摘要： A portable media player receives encrypted audio files and an encrypted content key from a central license server on the Internet. The media player supports digital rights management (DRM) by storing the encrypted audio file in its flash memory and disabling copying or playing of the audio file after a copy limit has been reached. The copy limit is a rule that is combined with the content key in a transfer key that can be encrypted together by the license server. The license server can detect cloning of the media player by reading a unique player ID from the player and detecting when too many accounts use the same unique player ID. The content key can be generated from polar coordinates of the unique player ID, player manufacturer, and song genre. A fingerprint sensor on the player can scan and compare the user's fingerprints to further detect cloning.

摘要翻译： 便携式媒体播放器从互联网上的中央许可证服务器接收加密的音频文件和加密的内容密钥。 媒体播放器通过将加密的音频文件存储在其闪存中来支持数字权限管理（DRM），并且在达到复制限制之后禁用复制或播放音频文件。 复制限制是与许可证服务器可一起加密的传输密钥中的内容密钥相结合的规则。 许可证服务器可以通过从播放器中读取唯一的播放器ID来检测媒体播放器的克隆，并检测何时太多的帐户使用相同的唯一播放器ID。 内容密钥可以由唯一播放器ID，播放器制造商和歌曲类型的极坐标生成。 播放器上的指纹传感器可以扫描并比较用户的指纹，以进一步检测克隆。

摘要： A flash-memory cache card caches data that a host writes to a hard disk drive. A flash-memory array has physical blocks of flash memory arranged into first and second data areas having M blocks each, and a wear-leveling-counter pool. An incoming logical sector address (LSA) from a host is mapped to one of M entries in a RAM lookup table using a hash of modulo M. The RAM entry stores a mapping to a physical block in a foreground area that is either the first or the second data area. Pages in the physical block are read for a matching LSA that indicates a cache hit. Full pages are written back to the hard disk and erased in the background while the other data area becomes the foreground area. A new physical block with a low wear-level count is selected from blocks in the new foreground area.

摘要： A flash-memory drive replaces a hard-disk drive using an integrated device electronics (IDE) interface. The flash drive has a printed-circuit board assembly (PCBA) with a circuit board with flash-memory chips and a controller chip. The controller chip includes an input/output interface circuit to an external computer over the IDE interface, and a processing unit to read blocks of data from the flash-memory chips. The PCBA is encased inside an upper case and a lower case, with an IDE connector that fits through and opening between the cases. The cases can be assembled with the PCBA by a snap-together, ultrasonic-press, screw-fastener, or thermal-bond adhesive method. Center lines formed on the inside of the cases fit between rows of flash-memory chips to improve case rigidity. The connector has two rows of pins that straddle the center line of the circuit board for a balanced design.

摘要： A pen-type computer peripheral device includes an elongated housing containing a PCBA having a plug connector and a fingerprint sensor mounted thereon. The PCBA is secured to a positioning member that is actuated by way of a press-push button that is exposed through a slot defined in a wall of the housing. By pressing and pushing (sliding) the press-push button along the slot, the fingerprint sensor and the plug connector are moved between a retracted position, in which the fingerprint sensor is positioned inside of the housing and the plug connector is covered by a portion of the housing wall, and a deployed position in which the fingerprint sensor is exposed through the slot and the plug connector extends through a front housing opening such that both the fingerprint sensor and the plug connector are exposed outside of the housing.

摘要： A Universal-Serial-Bus (USB) device has a USB plug with reduced wobble. A USB metal wrap around the perimeter of the USB plug is attached to a housing by overmolding. A plug supporter is inserted into the front of the USB metal wrap, and has locking tabs that snap over the inside wall of the housing. Side tabs on the plug supporter fit into side slots on the USB metal wrap to secure the plug supporter inside the USB metal wrap. A circuit board with a USB flash controller has USB metal contacts on an extension end that is inserted through the housing and into the USB metal wrap. The extension end fits underneath top tabs on the plug supporter, preventing the extension end with the USB metal contacts from upward wobble when the USB plug is inserted into a USB socket.
