  • Patent number: 9259167
    Abstract: This invention discloses a system and method for extracting VF signal in ECG recorded during uninterrupted CPR. The method and system applies an adaptive algorithm incorporating the EMD and least mean square (LMS) filtering to effectively model the CPR artifacts such as chest compression signals. Thus, A VF signal in ECG recorded during uninterrupted CPR can be extracted without deteriorating the reliability of the waveform parameter (i.e. AMSA) of shockability. The present invention enables uninterrupted CPR performed during recording ECG for accessing the shockability, so that an increase the probability of successful resuscitation is achieved.

  • Patent number: 9254266
    Abstract: The present invention provides surface-stabilized amorphous pharmaceuticals comprising an amorphous pharmaceutical substrate coated with a biocompatible immobilizing material. Amorphous pharmaceutical substrates that are prone to surface enhanced crystallization benefit from the present coatings. The coated amorphous pharmaceuticals of the present invention maintain their amorphous state and, therefore, their solubility over extended periods of time, relative to uncoated pharmaceuticals.

  • Patent number: 9004752
    Abstract: A viable strategy to enhance the bioavailability of poorly soluble drugs is to use amorphous solids in place of the more commonly used crystalline solids in pharmaceutical formulations. However, amorphous solids are physically meta-stable and tend to revert back to their crystalline counterpart. An effective approach to stabilizing an amorphous drug against crystallization is to disperse it in a polymer matrix. The drug's solubility in the chosen polymer defines the upper limit of drug loading without any risk of crystallization. Measuring the solubility of a drug in a polymer has been a scientific and technological challenge because the high viscosity of polymers makes achieving solubility equilibrium difficult and because pharmaceutically important drug/polymer dispersions are glasses, which undergo structural relaxation over time. The invention provides a method based on Differential Scanning calorimetry (DSC) for measuring the solubility of crystalline drugs in polymeric matrices.

  • Publication number: 20130199313
    Abstract: A method for evaluating the solubility of a crystalline substance in a polymer comprises a) providing at least one sample of an intimate crystalline substance/polymer mixture at a predetermined crystalline substance concentration; b) annealing the sample at a constant temperature Ta for a period of time; c) heating the annealed sample while recording the heat flux over time by DSC; d) identifying a DSC dissolution endotherm in the recorded heat flux, if any; e) considering the crystalline substance concentration as a concentration above the crystalline substance solubility in the polymer at temperature Ta when there is a DSC dissolution endotherm identified, and considering the crystalline substance concentration as a concentration less than or equal to the crystalline substance solubility in the polymer at temperature Ta when there is no DSC dissolution endotherm identified.

  • Patent number: 8380305
    Abstract: A computer-assisted method for quantitative characterization and treatment of ventricular fibrillation includes acquiring a time series of a ventricular fibrillation (VF) signal using a probe from a patient experiencing VF, subtracting the mean from the time series of the VF signal, calculating a cumulative VF signal after the mean is subtracted from the time series of the VF signal, segmenting the cumulative VF signal by a plurality of sampling boxes, calculating the root-mean-square of the cumulative VF signal as a function of the sampling box size , extracting an exponent of the root-mean-square of the cumulative VF signal as a function of the sampling box size, applying electrical defibrillation to the patient if the exponent is below a predetermined value, and applying cardiopulmonary resuscitation (CPR) to the patient if the exponent is above a predetermined value.

  • Publication number: 20080154140
    Abstract: A carotid pulse measurement device provided for measuring carotid pulse of a user's neck includes a band, an artery-pressing air cell, an inflating/deflating device, and a pressure detection unit. The band functions to surround the user's neck. The air cell is arranged in the band and is fluidly connected to the inflating/deflating device for selectively inflating/deflating the air cell. The pressure detection unit detects variation of pressure inside the air cell. To use the measurement device, the band is put around the user's neck with the air cell positioned exactly corresponding to the carotid artery of the neck so that the pressure detection device detects the pressure variation and generates a digital pulse signal, which is employed to calculate arteriosclerosis index of the user for evaluation the degree of arteriosclerosis of the user.

  • Publication number: 20070100644
    Abstract: A website for marketing real estate or products relating to real estate includes personal webspaces for users. Assigned user roles determine which capabilities they may configure into their webspaces. Users may communicate with each other and with merchants, e.g., by sharing webspaces or by dialogs. Merchants may send product information only certain users in response to users' expressed or inferred desires. Collected product and user data may be used to calculate propensities of individual users, marketability of individual products, or market trends.
