摘要:
A solid-state mass storage device and method for its operation that includes performing preemptive scrubbing of data during offline periods or disconnects from a host system to which the mass storage device is attached. The device includes a system interface adapted to connect the drive to a host system, at least one nonvolatile memory device, controller means through which data pass when being written to and read from the memory device, a volatile memory cache, a system logic device, and an integrated power source for powering the drive. The system logic device is configured to operate when the drive is not functionally connected to a host system, execute copy commands without accessing a host system, and prioritize preemptive scrubbing of addresses in the memory device on the basis of risk of data loss based on one or more parameters logged by the internal system logic device.

Methods and memory modules adapted for use in computer systems to generate different voltages for core supply (VDD) and input/output supply (VDDQ) inputs to memory components of the computer memory subsystem. The memory module includes a substrate with an edge connector, a memory component, and first and second voltage planes adapted to supply the core supply voltage and the input/output supply voltage to the memory component. The first voltage plane receives a system input voltage from the edge connector, and the second voltage plane is connected to the first voltage plane to receive a second voltage that is either higher or lower than the system input voltage. One of the first and second voltage planes is connected to the memory component to supply the core supply voltage thereto, and the other voltage plane supplies the input/output supply voltage to the memory component.
摘要:
A NAND-based flash memory device and a method of its operation that extends the life of the device by reducing the number of unnecessary write cycles to the device. The memory device includes blocks, pages contained by each of the blocks, and a page abstraction layer containing a look-up table for translating logical page numbers into physical page numbers. A certain number of the pages in at least one of the blocks is preferably reserved so as not to be used in default data storage mode but instead used to shuffle data within the at least one block using a dynamic page address scheme, whereby data are dynamically moved from one page to an empty page in the same block using dynamic page mapping.
摘要:
The present invention is directed to an apparatus and method for the stabilization and fastening of two pieces of tissue. A single device may be used to both stabilize and fasten the two pieces of tissue, or a separate stabilizing device may be used in conjunction with a fastening device. The stabilizing device may comprise a probe with vacuum ports and/or mechanical clamps disposed at the distal end to approximate the two pieces of tissue. After the pieces of tissue are stabilized, they are fastened together using sutures or clips. One exemplary embodiment of a suture-based fastener comprises a toggle and suture arrangement deployed by a needle, wherein the needle enters the front side of the tissue and exits the blind side. In a second exemplary embodiment, the suture-based fastener comprises a needle connected to a suture. The needle enters the blind side of the tissue and exits the front side. The suture is then tied in a knot to secure the pieces of tissue. One example of a clip-based fastener comprises a spring-loaded clip having two arms with tapered distal ends and barbs. The probe includes a deployment mechanism which causes the clip to pierce and lockingly secure the two pieces of tissue.

A display system includes a mechanism to provide for simultaneous pixelated color with a spatial light modulator. Also included is a mechanism to project the simultaneous pixelated color to create a color field display on a viewing surface. A further mechanism moves the color field display relative to viewing surface to provide at least one of color and resolution increasing wobulation.
摘要:
A display system may include an identifier configured to identify an image display condition associated with the display of an image produced by the display system, an apparatus configured to produce a plurality of differently colored images, and a display device. The images have color characteristics based on image information and the identified display condition. Differently colored images may be directed along associated portions of an optical path. The display device may be coupled to the apparatus and may be configured to display a color image formed of the differently colored images.

A system for producing a composite image in a multiple projection system includes at least two projectors, a dynamic image shifting mechanism, associated with at least one of the two projectors, and a controller, connected to control each projector and the image shifting mechanism. Each projector is configured to project a component image to a projection surface at an image refresh rate, and the dynamic image shifting mechanism is configured to shift a projection path of the component image of the at least one projector. The controller is configured to modify image data sent to the at least one projector and to shift the dynamic image shifting device to produce a single composite image comprising the at least two component images.

A display system is configured to produce a color image formed of a plurality of differently colored images and may include at least one light source that directs light along an optical path, and at least one filter having a given optical filter characteristic. The display system may be selectively operable in a first state in which the optical path does not pass through a first filter during production of the plurality of differently colored images to form a color image having a first optical characteristic, and in a second state in which the optical path passes through the first filter during production of the plurality of differently colored images to form a color image having a second optical characteristic different than the first optical characteristic.
