Publication number: 20180048232Abstract: An autozeroed comparator controls a frequency fsw of the input voltage inputted to a DC/DC converter. A digital frequency synchronization circuit is connected to the autozeroed comparator so as to form a phase locked loop, wherein the DES circuit controls the hysteretic window of the autozeroed comparator so as to lock fsw to a clock reference frequency. A plurality of slave phase circuits may be connected to the master phase circuit including the DFS circuit and the autozeroed comparator. Duty cycle calibration circuits adjust a duty cycle signal applied to each of the slave phase circuits, in response to average current measured in the slave phase circuits, so that each slave phase circuit is synchronized with the master phase circuit. A 6 A 90.5% peak efficiency 4-phase hysteretic quasi-current-mode buck converter is provided with constant frequency and maximum ±1.5% current mismatch between the slave phases and the master phase.Type: ApplicationFiled: August 9, 2017Publication date: February 15, 2018Applicants: California Institute of Technology, Arizona Board of Regents, a body Corporate of the State of Arizona, on behalf of Arizona State UniveInventors: Philippe C.

Patent number: 9779497Abstract: Measuring the number of glomeruli in the entire, intact kidney using non-destructive techniques is of immense importance in studying several renal and systemic diseases. In particular, a recent Magnetic Resonance Imaging (MRI) technique, based on injection of a contrast agent, cationic ferritin, has been effective in identifying glomerular regions in the kidney. In various embodiments, a low-complexity, high accuracy method for obtaining the glomerular count from such kidney MRI images is described. This method employs a patch-based approach for identifying a low-dimensional embedding that enables the separation of glomeruli regions from the rest. By using only a few images marked by the expert for learning the model, the method provides an accurate estimate of the glomerular number for any kidney image obtained with the contrast agent. In addition, the implementation of our method shows that this method is near real-time, and can process about 5 images per second.Type: GrantFiled: September 14, 2015Date of Patent: October 3, 2017Assignee: ARIZONA BOARD OF REGENTS, A BODY CORPORATE OF THE STATE OF ARIZONA, ACTING FOR AND ON BEHALF OF ARIZONA STATE UNIVERSITYInventors: Jayaraman Jayaraman Thiagarajan, Karthikeyan Ramamurthy, Andreas Spanias, David Frakes

Patent number: 9710916Abstract: A robust method to automatically segment and identify tumor regions in medical images is extremely valuable for clinical diagnosis and disease modeling. In various embodiments, an efficient algorithm uses sparse models in feature spaces to identify pixels belonging to tumorous regions. By fusing both intensity and spatial location information of the pixels, this technique can automatically localize tumor regions without user intervention. Using a few expert-segmented training images, a sparse coding-based classifier is learned. For a new test image, the sparse code obtained from every pixel is tested with the classifier to determine if it belongs to a tumor region. Particular embodiments also provide a highly accurate, low-complexity procedure for cases when the user can provide an initial estimate of the tumor in a test image.Type: GrantFiled: September 14, 2015Date of Patent: July 18, 2017Assignee: ARIZONA BOARD OF REGENTS, A BODY CORPORATE OF THE STATE OF ARIZONA, ACTING FOR AND ON BEHALF OF ARIZONA STATE UNIVERSITYInventors: Jayaraman Jayaraman Thiagarajan, Karthikeyan Ramamurthy, Andreas Spanias, David Frakes
