Abstract: A method of detecting an error in a security mode configuration procedure conducted at a radio access network is provided. A cell update message is transmitted which causes the radio access network to abort a security mode configuration procedure. After the transmission of an update message, a new security mode configuration is received and the original security mode configuration is replaced with a new security mode configuration. A security mode configuration check is performed on a received downlink message using the new security mode configuration. If the security mode configuration check fails, a further security mode configuration check is performed on the downlink message to detect an error in the security mode configuration procedure. If it is determined there has been an error in the security mode configuration procedure, security mode configuration checks are performed on further downlink messages received from the network using the original security mode configuration.
Abstract: Methods and systems for reducing or eliminating distortion in an image are described. The approach generally involves determining the distortion introduced by a lens, and modifying a captured image to reduce that distortion. In one embodiment, the distortion information associated with a lens is determined. The distortion information is stored. A captured image taken by that lens is processed, with reference to the distortion information.

Abstract: A processor and a system are provided for performing texturing operations loaded from a texture queue that provides temporary storage of texture coordinates and texture values. The processor includes a texture queue implemented in a memory of the processor, a crossbar coupled to the texture queue, and one or more texture units coupled to the texture queue via the crossbar. The crossbar is configured to reorder texture coordinates for consumption by the one or more texture units and to reorder texture values received from the one or more texture units.
Abstract: A technique for providing electrostatic discharge (ESD) protection in complementary metal-oxide semiconductor (CMOS) technologies is disclosed. A power supply RC-based ESD protection circuit having an RC value in the nanosecond range increases the allowable power-up slew rate so that fast power-up events (e.g., hot-plug and power switching operations) are not erroneously interpreted as ESD events. Because the RC value is small, the layout area needed for the RC-based ESD protection circuit is also reduced.
Abstract: Method including casting a first plurality of rays towards an original 3-D scene comprising objects with object surfaces. Method also includes constructing a simplified representation of the original 3-D scene and adjusting the simplified representation to be consistent with the original 3-D scene. Simplified representation is adjusted by using known rays and object surface intersections obtained from the casting, to produce an adjusted simplified representation.

Abstract: A system and method for re-factorizing a square input matrix on a parallel processor. In one embodiment, the system includes: (1) a matrix generator operable to generate an intermediate matrix by embedding a permuted form of the input matrix in a zeroed-out sparsity pattern of a combination of lower and upper triangular matrices resulting from a prior LU factorization of a previous matrix having a same sparsity pattern, reordering to minimize fill-in and pivoting strategy as the input matrix and (2) a re-factorizer associated with the matrix generator and operable to use parallel threads to apply an incomplete-LU factorization with zero fill-in on the intermediate matrix.

The multi-band antenna, in this aspect, further includes a second resonant portion having a second length defined by an inner perimeter of the conductive segment and operable to resonate capacitively for communication in a second different band of frequencies.
Abstract: Embodiments of the present invention are directed to provide novel methods and a system for adaptive resolution rendering via scaling in a multiple graphics processor system. A method is described herein that maintains a constant framerate by reducing the resolution of the graphical output rendered in one graphics processor and using another graphics processor in the same computing system to scale the already-rendered output to its original intended resolution when the framerate drops below a desired threshold.

Abstract: A method and apparatus for performing display image refresh in bursts to a display device. A buffered refresh controller includes capabilities to drive the display based on video signals generated from a local frame buffer at a first rate. The graphics controller may optimally be configured to burst a new frame of pixel data to the buffered refresh controller at a second rate to replace the previous frame of pixel data in the local frame buffer. The second rate is different than the first rate. Additionally, the graphics controller may send frames only when they contain new pixel data. By enabling the graphics controller to selectively transmit the new frame of pixel data at the second rate, higher than the first rate, the graphics controller may be placed in a power-saving state during at least a portion of each frame update.
