Abstract: A shielding device includes a shielding member, a magnet fixed to the shielding member, a support for supporting and allowing movement of the shielding member in a direction parallel to an X-axis, and a coil wound in a hollow cylindrical shape with a winding axis parallel to the X-axis. Herein, at least a portion of the magnet is inserted into an inner side of the coil. The shielding device controls the shielding member by leveraging magnetism, which is simple and damage-proof. An electric driving structure includes the coil wound in the hollow cylindrical shape and the magnet inserted into the inner side of the coil, which can be structured compactly and thus suitable for use in various electronic apparatuses such as ultra-thin displays, laptops, and desktop computers.

Abstract: A lens driving device capable of efficiently inhibiting garbage from falling to the side of a photosensitive sensor includes a lens support for retaining a lens, a fixed member, one or two spring members for connecting the lens support and the fixed member, and an electromagnetic driving assembly. The fixed member includes a substrate defining a circular through hole, a cylindrical dividing wall extending from an edge defining the circular through hole, several protruding parts protruding from the substrate outside the dividing wall, and concave parts formed between the protruding parts and the dividing wall. The lens support is provided with an end face capable of contacting a second front end face of the protruding parts and opposite to the concave parts, and a ring-shaped end surface arranged opposite to an end face of the dividing wall.

Abstract: A memory registration abstraction layer includes decision logic for dynamic, efficient determination of memory copy versus registration. The exemplary embodiments apply to direct memory access environments. The memory registration abstraction layer also includes tracking logic for monitoring the usage history for certain ranges of memory registration requests. The registration logic chooses to copy memory or map memory based on training and observation of application behavior, taking the more efficient performance path without requiring changes to the application.

Abstract: A method, apparatus, and computer instructions for facilitating failover between network adapters. A failure of a first network adapter is detected in a device driver layer. In response to detecting the failure, the transmission of data is changed by the device driver layer to a second network adapter.
