Publication number: 20140213876Abstract: The invention provides an electrode and associated electrode holder that are used for physiological measurements, e.g. measurements of signals that can be processed to generate ECG and TBI waveforms. The electrode and electrode holder connect to each other using a magnetic interface. In embodiments, for example, the magnetic interface includes oppositely polled magnets integrated in both the electrode and electrode holder. The magnets are typically rare earth magnets coated with a thin, electrically conductive metal film. This way, when the magnets come in contact with each other, the metal films touch to form both a mechanical and electrical connection. Thus the magnetic interface can replace conventional mechanisms used to connect rivet-based electrodes to leads, which are typically used to secure electrodes for physiological measurements.Type: ApplicationFiled: January 29, 2014Publication date: July 31, 2014Applicant: Perminova Inc.Inventors: Matt Banet, Susan Pede, Marshal Dhillon, Drew Terry

Publication number: 20140213887Abstract: CEST imaging technique and MR scanning are used as an MRI method for measuring glutaminase mediated tumors. The method takes advantage of the fact that glutamine does not exhibit a significant Chemical Exchange Saturation Transfer (CEST) effect while glutamate does. In accordance with this method, one first obtains a glutamate CEST MRI map of the area of a tumor. L-glutamine (nontoxic up to several millimolar level) or glutaminase blocker is then injected and a post injection Glutamate CEST map is obtained. The difference in the spatial maps indicates the level of expression of glutaminase in the tumor.Type: ApplicationFiled: March 31, 2014Publication date: July 31, 2014Applicant: The Trustees of the University of PennsylvaniaInventors: Ravinder Reddy, Hari Hariharan, Catherine DeBrosse, Ravi Prakash Reddy Nanga

Publication number: 20140213909Abstract: What is disclosed is a system and method for estimating a biological parameter vector for a biophysics model using reflectance measurements obtained from a reflectance-based spectral measurement system. The present method uses a semi-empirical biophysics model to describe skin properties and estimate reflectance spectra and reduces the dimensionality of the estimated and measured reflectance spectra using basis vectors for computational efficiency. A mixture of algorithms are employed to generate an initial set of parameters which, in turn, are further refined using an iterative control based technique in which the error between the parameters derived from the measured spectra are compared to the parameters calculated from the estimated spectra. These errors are then processed to generate a small delta to the initial set of parameters.Type: ApplicationFiled: January 31, 2013Publication date: July 31, 2014Applicant: XEROX CORPORATIONInventors: Lalit Keshav MESTHA, Palghat Srinivas RAMESH, Alvaro Enrique GIL

Publication number: 20140213910Abstract: Frequent monitoring of early-stage burns is necessary for deciding optimal treatment and management. Superficial-partial thickness and deep-partial thickness burns, while visually similar, differ dramatically in terms of clinical treatment and are known to progress in severity over time. The disclosed method uses spatial frequency domain imaging (SFDI) far noninvasively mapping quantitative changes in chromophore and optical properties that may be an indicative of burn wound severity. A controlled protocol of graded burn severity is developed and applied to 17 rats. SFDI data is acquired at multiple near-infrared wavelengths over a course of 3 h. Burn severity is verified using hematoxylin and eosin histology. Changes in water concentration (edema), deoxygenated hemoglobin concentration, and optical scattering (tissue denaturation) are statistically significant measures, which are used to differentiate superficial partial-thickness burns from deep-partial thickness burns.Type: ApplicationFiled: January 24, 2014Publication date: July 31, 2014Applicant: The Regents of the University of CaliforniaInventors: Anthony J.

In one embodiment of the invention, not only are the first four moments (mean, standard deviation, skewness, and kurtosis) of the pressure waveform used to estimate the cardiovascular parameter(s) of interest, but also heart rate, statistical moments of a set of pressure-weighted time values, and certain anthropometric patient measurements such as age, sex, body surface area, etc.Type: ApplicationFiled: March 28, 2014Publication date: July 31, 2014Applicant: Edwards Lifesciences CorporationInventor: Luchy Roteliuk

Publication number: 20140213920Abstract: An activity monitor such as a wrist-worn device has an accelerometer which continuously detects motion of the user. The activity monitor also has an on-demand heart rate monitor which is activated by the user touching it from time to time. A calorie expenditure based on the motion of the user can be modified based on a heart rate measurement. Further, a determination can be made as to whether the user has made repetitive motions for a period of time. If the repetitive motions are detected, a calorie expenditure based on the heart rate is determined and compared to the calorie expenditure based on the user motion, and the higher value prevails. A situation is avoided in which the activity monitor underestimates the calories expended, such as when the user is exercising strenuously but the accelerometer indicates relatively little motion, e.g., during strength training.Type: ApplicationFiled: January 31, 2013Publication date: July 31, 2014Applicant: Salutron, Inc,Inventors: Yong Jin Lee, Eddy Hui, Kaiping Chen

Publication number: 20140213921Abstract: A cardiac-based metric is computed based upon characteristics of a subject's cardiac function. In accordance with one or more embodiments, the end of a mechanical systole is identified for each of a plurality of cardiac cycles of a subject, based upon an acoustical vibration associated with closure of an aortic valve during the cardiac cycle. The end of an electrical systole of an electrocardiogram (ECG) signal for each cardiac cycle is also identified. A cardiac-based metric is computed, based upon a time difference between the end of the electrical systole and the end of the mechanical systole, for the respective cardiac cycles.Type: ApplicationFiled: March 31, 2014Publication date: July 31, 2014Applicant: VivaQuant LLCInventors: MARINA BROCKWAY, BRIAN BROCKWAY, ROBERT HAMLIN
