    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 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.

    摘要： A case-grounded flash-memory drive has a printed-circuit board assembly (PCBA) with flash-memory chips and a controller chip. The PCBA is encased inside an upper case and a lower case, with a Serial AT-Attachment (SATA) 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. Dual-axis case-grounding pins draw any electro-static-discharges (ESD) current off the upper case along a primary axis and onto a PCBA ground through a secondary axis washer that is screwed into the PCBA. The primary axis body of the dual-axis case-grounding pins fits around a PCBA notch while the secondary axis passes through a metalized alignment hole for grounding. When the SATA connector is inserted into a host, the host ground sinks ESD currents collected by the dual-axis case-grounding pins.

    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： An extended Universal-Serial Bus (EUSB) bridge to a host computer can have Peripheral Components Interconnect Express (PCIE) protocol layers on one side of the bridge, and EUSB layers on the other side of the bridge, with a high-level bridging converter module connecting the upper layers. The PCIE physical, data-link, and transport layers may be eliminated by integrating the bridge with an I/O controller. PCIE requests and data payloads are directly sent to the bridge, rather than low-level PCIE physical signals. The PCIE data payloads are converted to EUSB data payloads by a high-level direct bridging converter module. Then the EUSB data payloads are passed down to an EUSB transaction layer, an EUSB data-link layer, and an EUSB physical layer which drives and senses physical electrical signals on both differential pairs of the EUSB bus.

    摘要： A sliding window of flash blocks is used to reduce wasted space occupied by stale data in a flash memory. The sliding window slides downward over a few flash blocks. The oldest block is examined for valid pages of data, and the valid pages are copied to the end of the sliding window so that the first block has only stale pages. The first block can then be erased and eventually re-used. A RAM usage table contains valid bits for pages in each block in the sliding window. A page's valid bit is changed from an erased, unwritten state to a valid state when data is written to the page. Later, when new host data replaces that data, the old page's valid bit is set to the stale state. A RAM stale-flags table keeps track of pages that are full of stale pages.
