Abstract: Disclosed are aspects of communication between user-space and kernel-space. In some examples, an application programming interface (API) signature is defined for an API. The API signature specifies a callback and a callback parameter size. A transport allocates temporary storage based on the callback parameter size specified by the API signature. A callback parameter is stored in the temporary storage. The callback is invoked based on the callback parameter.

Abstract: Embodiments of the disclosure provide high-level primitives that facilitate communication between a user-space application and an operating system kernel. Transport components reside in user-space and in kernel-space that, upon either the application or a kernel module requesting to invoke a callback, deliver parameters and other data back and forth to one another, allowing the user-space application and kernel module to communicate as if directly invoking the callback. Embodiments also provide for a definition standard that third-party developers can use to automatically emit a header file and macros for sending events and dispatching callbacks.

Abstract: This invention provides a device of Flash Modules Array or Flash Array (FA) for short, with a higher capacity, higher speed and lower power consumption. A device of flash array comprises: a one or more physical I/O interfaces, for performing data transmission with the outside or upstream; one or more ports for flash modules consisting of multiple flash memory modules, a flash array controller, set between the physical I/O interface and the flash modules, further including: a block mapping unit, for performing the address mapping between the logical address which is transmitted between the physical I/O interface and the outside and the physical address which is transmitted between the physical I/O interface and the flash array. The invention is applied in the field of flexible solid state storage device.

Abstract: A disk to be coated on both sides in rotatively supported within an annular housing of a larger internal diameter. Means traverse and coat each side of the rotating disk. The inner housing wall is disposed transversely to the disk and has an annular slot operatively associated with the disk whereby excess coating material is spun off the disk and into the housing. The housing is radially of a triangular cross-section, the apex offset from said disk whereby said spun off material strikes an inclined internal wall surface of the housing. Means orbit a plurality of such disks about a central axis and through a plurality of movable treating stations.

Abstract: A high-speed roller system for transporting webs of sheeting, preferably for coating the same with a magnetic layer, comprising a suction roller for control of the speed of the web, which suction roller has a surface containing grooves, preferably rhombic grooves, in which the perforations for sucking the sheeting are disposed, preferably at the points of intersection, the ratio of the total cross-sectional area of the perforations to the total surface area of the roller being from 0.7 to 3%.
