| 20110251210 | MODIFIED CHLOROQUINES WITH SINGLE RING MOIETY OR FUSED RING MOIETY - The disclosure provides modified chloroquine compounds having single ring or fused ring moieties. Also provided are pharmaceutical compositions comprising such compounds, methods of using such compounds to inhibit or treat diseases or conditions caused by chloroquine-resistant (CQ | 10-13-2011 |
| 20110213277 | SYSTEM, METHOD, AND APPARATUS FOR OBJECTIVE ASSESSMENT OF MOTOR SIGNS AT THE EXTREMITIES - Disclosed embodiments include a system for objective assessment of motor signs at the extremities that comprises (a) a device for objective motor sign measurement, (b) a test protocol defining a prescribed repetitive activity, and (c) a signal processing and analysis system to generate one or more impairment metrics. According to a particular embodiment, the device for objective motor sign measurement is characterized by including means for producing a continuous measure of position of a limb or extremity during said prescribed repetitive activity during the entire movement. | 09-01-2011 |
| 20100232504 | Supporting region-of-interest cropping through constrained compression - Region-of-interest cropping of high-resolution video is supported video compression and extraction methods. The compression method divides each frame into virtual tiles, each containing a rectangular array of macroblocks. Intra-frame compression uses constrained motion estimation to ensure that no macroblock references data beyond the edge of a tile. Extra slice headers are included on the left side of every macroblock row in the tiles to permit access to macroblocks on the left edge of each tile during extraction. The compression method may also include breaking skipped macroblock runs into multiple smaller skipped macroblock runs. The extraction method removes slices from virtual tiles that intersect the region-of-interest to produce cropped frames. The cropped digital video stream and the compressed digital video stream have the same video sequence header information. | 09-16-2010 |
| 20100223697 | Systems for assessing and enhancing the performance of scanning probe microscopes by quantifying and enforcing symmetries and periodicities in two dimensions - Scanning probe microscope (SPM) images are enhanced by enforcing one or more symmetries that can be selected based on suitable Fourier coefficient amplitude or phase angle residuals, and/or geometric Akaike information criteria, and/or cross correlation techniques. Alternatively, this selection can be based on prior knowledge of specimen characteristics. In addition, a scanning microscope point spread function is obtained based on the evaluation of a calibration image by enforcing at least one symmetry and can be applied to other image acquisitions. | 09-02-2010 |
