| 20090027407 | DATA ACCESS TOOL FOR PROGRAMMABLE GRAPHICS HARDWARE - Methods and apparatuses for accessing data within programmable graphics hardware are provided. According to one aspect, a user inserts special log commands into a software program, which is compiled into instructions for the programmable graphics hardware to execute. The hardware writes data to an external memory during runtime according to a flow control protocol, and the software driver reads the data from the memory to display to the user. | 01-29-2009 |
| 20090033672 | SCHEME FOR VARYING PACKING AND LINKING IN GRAPHICS SYSTEMS - A wireless device which performs a first-level compiler packing process and a second-level hardware packing process on varyings. The compiler packing process packs two or more shader variables (varyings or attributes) whose sum of components equals M into a shared M-dimensional (MD) vector register. The hardware packing consecutively packs M components of the shader variables (varyings or attributes) and any remaining variables into a vertex cache or other storage medium. | 02-05-2009 |
| 20100141659 | DISCARDING OF VERTEX POINTS DURING TWO-DIMENSIONAL GRAPHICS RENDERING USING THREE-DIMENSIONAL GRAPHICS HARDWARE - This disclosure describes techniques for removing vertex points during two-dimensional (2D) graphics rendering using three-dimensional (3D) graphics hardware. In accordance with the described techniques one or more vertex points may be removed during 2D graphics rendering using 3D graphics hardware. For example, the techniques may remove redundant vertex points in the display coordinate space by discarding vertex points that have the substantially same positional coordinates in the display coordinate space as a previous vertex point. Alternatively or additionally, the techniques may remove excess vertex points that lie in a straight line. Removing the redundant vertex points or vertex points that lie in a straight line allow for more efficient utilization of the hardware resources of the GPU and increase the speed at which the GPU renders the image for display. | 06-10-2010 |

| 20100086127 | EFFICIENT IMPLEMENTATION OF ARITHMETICAL SECURE HASH TECHNIQUES - An apparatus including an initialization circuit and a hash computation circuit. The initialization circuit may be configured to present a number of initialization values. The hash computation circuit may be configured to generate hash values for the message in response to the padded message blocks and the initialization values. The hash computation circuit generally performs a diagonal cut technique that simultaneously uses values from a plurality of different cycle rounds in a single cycle round analog. | 04-08-2010 |

| 20100014655 | Method and apparatus for generating cryptographic key using biometric data - A method of securely storing and authenticating biometric data against attacks of a third party includes encoding input biometric data, and applying a one-way function to the encoded biometric data. A first exclusive OR operation is performed to the result of the one-way function and a selected secret key. The result of the first exclusive OR operation is encoded, and a second exclusive OR operation is performed to the encoded result of the first exclusive OR operation and the encoded biometric data. The result of the second exclusive OR operation is stored. In the same manner, the biometric data is authenticated. Accordingly, the biometric data can be securely stored against the attacks of a third party by processing and storing the biometric data according to a predetermined procedure. | 01-21-2010 |

| 20100214448 | Video Acquisition with Processing Based on Ancillary Data - Systems and techniques for processing sequences of video images involve receiving, on a computer, data corresponding to a sequence of video images detected by an image sensor. The received data is processed using a graphics processor to adjust one or more visual characteristics of the video images corresponding to the received data. The received data can include video data defining pixel values and ancillary data relating to settings on the image sensor. The video data can be processed in accordance with ancillary data to adjust the visual characteristics, which can include filtering the images, blending images, and/or other processing operations. | 08-26-2010 |

| 20100222690 | Differentiating Ischemic From Non-Ischemic T-Wave Inversion - A method of discriminating between ischemic and cardiac memory effects in a heart, comprising receiving electrocardiographic (ECG) data, calculating, from the ECG data, a direction of a T-wave vector, diagnosing ischemia if the T-wave vector is between about 75 degrees and about 200 degrees, and diagnosing cardiac memory if the T-wave vector is between about zero degrees and minus 90 degrees. Also presented is a system for discriminating between ischemic and cardiac memory effects in a heart comprising means for performing an electrocardiogram, means for calculating a direction of a T-wave vector, means for diagnosing ischemia if the T-wave vector is between about 90 degrees and 180 degrees, and means for diagnosing cardiac memory if the T-wave vector is between about zero degrees and minus 90 degrees. | 09-02-2010 |
