摘要:
A storage layer may over-provision physical storage resources of a storage medium by reserving a portion of the full physical storage capacity of the storage medium for use as reserve capacity. The reserve capacity may be used to prevent write stall conditions and/or for grooming operations, such as storage recovery, refresh, and the like. A reserve module may be configured to adapt the reserve capacity in accordance with, inter alia, operating conditions on the storage layer. The reserve module may be configured to dynamically modify the storage capacity available through the storage layer. A cache layer configured to cache data of a backing store on the storage layer, may be configured to add and/or remove cache entries in response to changes in the reserve capacity.
摘要:
A small wearable recall device is provided to capture images triggered by a combination of a detection of a capture condition (e.g., changes in motion, temperature or light level) followed by a relatively stable period, as detected by an accelerometer. By triggering on the combination of a detected capture condition followed by a detected stability condition, a clearer image of the environment of an interesting event is expected to be captured. The small size of the recall device makes it possible to integrate it into common portable consumer products, such as MP3 players, purses, clothing, hats, backpacks, necklaces, collars, and other human-wearable products.
摘要:
Crankcase ventilation filter assemblies are described and shown. Components, features and methods of assembly and use are described. Many of the principles relate to preferred cartridge configurations for engagement with selected housings. Selected optional features described can be used to provide indication to a service provider that a proper cartridge is not positioned appropriately in the housing for use.
摘要:
According to the present disclosure, arrangements, systems, components, features and methods for separating hydrophobic fluid such as oil entrained as aerosols from gas streams, such as crankcase ventilation gas streams are described. The components specifically described include a filter cartridge with preferred features for interaction with a filter housing, and a filter housing with preferred features for convenient installation. Methods of assembly and use are also characterized
摘要:
A mattress is disclosed comprising a flexible frame for bearing uniaxial compressive stress from a human body pressed onto the frame. The frame traverses the breadth and length of the mattress in evenly-spaced repeating patterns which defines hollow recesses filled with materials like silicone gel, memory foam, coils, and springs. The flexible frame in some embodiments, has a higher compressive strength than does the traditional material(s) filled the recesses defined by the frame. The indentation force deflection (IFD) rating varies slightly across small, repeating regions the surface of the mattress. These regions provide lumbar, thoracic, and pelvic support to a user. A user may move about on the mattress during the night to adjust the areas of the small regions pressing most firmly against the body, selectively adjusting both the position of the body and the pressure points of the mattress to maximize comfort.
摘要:
An apparatus, system, and method are disclosed for improving performance in a non-volatile solid-state storage device. Non-volatile solid-state storage media includes a plurality of storage cells. An input module receives source data for storage in the plurality of storage cells of the non-volatile solid-state storage media. Some or all of the bits of the source data are transformed to take into account a voltage level of an empty state of the plurality of storage cells. A write module writes the transformed source data to the plurality of storage cells of the non-volatile solid-state storage media.
摘要:
An apparatus, system, and method are disclosed for storing information in a storage device that includes multi-level memory cells. The method involves storing data that is written to the storage device in the LSBs of the multi-level memory cells, and storing audit data in the MSBs of the multi-level memory cells. The audit data can be read separately from the data and used to determine whether or not there has been any unintended drift between states in the multi-level cells. The audit data may be used to correct data when the errors in the data are too numerous to be corrected using error correction code (ECC). The audit data may also be used to monitor the general health of the storage device. The monitoring process may run as a background process on the storage device. The storage device may transition the multi-level memory cells to operate as single-level memory cells.
摘要:
An apparatus, system, and method are disclosed for improving performance in a non-volatile solid-state storage device. Non-volatile solid-state storage media includes a plurality of storage cells. The plurality of storage cells is configured such that storage cells in an empty state store initial binary values that satisfy a bias. An input module receives source data for storage in the plurality of storage cells of the non-volatile solid-state storage media. Bits of the source data have a source bias that is different from the bias of the plurality of storage cells. A bit biasing module biases the bits of the source data toward the bias of the plurality of storage cells. A write module writes the biased source data to the plurality of storage cells of the non-volatile solid-state storage media.
摘要:
An apparatus, system, and method are disclosed for managing operations for data storage media. An adjustment module interrupts or otherwise adjusts execution of an executing operation on the data storage media. A schedule module executes a pending operation on the data storage media in response to adjusting execution of the executing operation. The pending operation comprises a higher execution priority than the executing operation. The schedule module finishes execution of the executing operation in response to completing execution of the pending operation.
摘要:
An apparatus, system, and method are disclosed to improve the utility of solid-state storage media by determining one or more configuration parameters for the solid-state storage media. A media characteristic module references one or more storage media characteristics for a set of storage cells of solid-state storage media. A configuration parameter module determines a configuration parameter for the set of storage cells based on the one or more storage media characteristics. A storage cell configuration module configures the set of storage cells to use the determined configuration parameter.
