Abstract:
A method and system for monitoring a signal from a function to record a set of values for each signal monitored; determining for each signal monitored the relative value of the signal being monitored over time; identifying each signal exhibiting a relative value representing a change in a pre-identified direction and each signal exhibiting a relative value not representing a change in the pre-identified direction, wherein each signal is aligned in the same direction relative to the pre-identified direction; dynamically weighting at least one signal monitored; displaying the monitored signals as an aggregate including enhancement of each signal exhibiting a change in the pre-identified direction; and causing a desired change in at least one monitored function based upon feedback of the displayed aggregate signals.
Abstract:
A noninvasive method for monitoring the blood pressure and arterial compliance of a patient based on measurements of a flow velocity and a pulse wave velocity is described. An embodiment uses a photoplethysmograph and includes a method to monitor the dynamic behavior of the arterial blood flow, coupled with a hemodynamic mathematical model of the arterial blood flow motion in a fully nonlinear vessel. A derived mathematical model creates the patient specific dependence of a blood pressure versus PWV and blood velocity, which allows continuous monitoring of arterial blood pressure.

Abstract:
A method for determining hearing thresholds in the absence of pure-tone testing includes an adaptive speech recognition test which includes a calibrated item pool, each item having a difficulty value (di) and associated standard error (se). Test items are administered to a group of individuals having mild to moderately severe hearing loss to obtain responses. The responses are subjected to multiple regression statistical methods to develop an equation for converting an individual's test score to hearing threshold values at several frequencies. The adaptive speech recognition test can be administered to an individual and their score can be converted into hearing thresholds at each of the several frequencies by use of the equation.
Abstract:
A method and system for treating emissions includes charging particles in an exhaust stream, producing one or more radicals, and oxidizing at least a portion of the charged particles with at least a portion of the produced radicals. At least a portion of the charged particles in the exhaust stream are then attracted on at least one attraction surface which is one of oppositely charged from the charged particles and grounded. The attracted particles are oxidized with another portion of the one or more produced radicals to self regenerate the at least one attraction surface. Downstream from where the attracted particles are oxidized, at least a portion of one or more first compounds in the exhaust stream are converted to one or more second compounds downstream from the attracting. Additionally, at least a portion of any remaining charged particles are oxidized into one or more gases.
