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.

A flash controller is adapted to communicate with a host and the flash memory and including volatile memory configured to store a page-block table of logical addresses addressable by the physical addresses. The logical addresses are used by the controller to identify the blocks. The table has an address mapping table and a property value table, the property value table includes property values, each of the property values being increased in value every time a block is written up to a maximum value and being associated with a block of a predetermined group of blocks and indicative of the number of times a block has been written, the property values corresponding to the logical addresses of the address mapping table, wherein the maximum number the property values of the predetermined group of blocks take on is adjustably different than the maximum number the property values of another group of blocks.
摘要:
The present invention provides a perfusion solution comprising specific metabolic agents, antioxidant agents, and membrane stabilizer agents that can help improve preservation, organ viability, and in some cases recover organs that would otherwise being unusable for transplantation. In a further embodiment, the perfusion solution can be used in combination with hypothermic machine perfusion. It has been found that combination of the perfusion solution and hypothermic machine perfusion can help prevent or reduce further damage to the organ and restore the organ's anti-oxidant system, stabilize the cellular cytoskeleton and cellular membranes, inhibit arachidonic acid pathway, provide oncotic support, reduce interstitial edema formation, and help restore energy stores within the organ. As a result, the method can be used to improve the viability of otherwise marginal donor organs.
摘要:
A system and method for implementing a flash memory system. The flash memory system includes a processor and at least one flash memory device. The at least one flash memory device includes a plurality of partitions. As a result, the flash memory system can utilize the multiple partitions to provide multiple functions such as an AutoRun feature.
摘要:
The invention related to apparatus for transferring flowable particulate material such as dry tablets, for example pharmaceutical tablets, from one station to another. The apparatus comprises a carrier for the tablets, and means externally of the carrier for moving the carrier between stations, the arrangement being such that the carrier and the means are not connected mechanically for movement of the carrier.
摘要:
A safety valve for a lawn sprinkler system having at least one subterranean flow line and at least one head for spraying irrigation water. The valve includes a tubular member connected between the flow line and the head. The tubular member has an axial passage therethrough for the flow of water from the flow line to the head. A seat is located within the passage. A ball is located in the passage upstream of the seat. The ball is axially movable from an open position upstream of the seat to a closed position in engagement with the seat if the water flowing through passage reaches a selected flow rate. A coiled spring in the passage is in engagement with the ball for urging the ball toward the open position
摘要:
A drainmast assembly (10) for ejecting gray water from the onboard potable water system of an aircraft. The assembly (10) includes an interface (14) mounted on the fuselage of the aircraft and a drainmast (16) including a fairing (90) aligned with and attached to the interface (14). The interface (14) includes a pipe (46) having an outlet nipple (48) which is pivotally connected to an inlet portion (146) of the draintube (94). In this manner, the draintube (94) can rotate relative to the interface (14) should the fairing (90) be unintentionally hit by a baggage vehicle and shoved out of alignment with the interface (14).

The invention features compositions and methods for diagnosing and treating chronic lymphocytic leukemia (CLL) based upon the absence or presence of a lesion, e.g., a deletion, at chromosome 14q32.33.
摘要:
An aircraft hot water supply system (10) comprising a group of water-use stations (14a-14f) each including a hot water line having a heater (40a-40f) which heats water at a heating rate dependent upon power provided thereto. A power manager (44) allocates different non-zero percentages of heater-dedicated power to different heaters (40) depending upon conditions at the corresponding water-use stations (14). A network (46) is provided to establish peer-to-peer communication among the heaters' controllers (48a-48f).
