  • Patent number: 9956364
    Abstract: Described are systems and methods for compensating long term sensitivity drift of catalytic type electrochemical gas sensors used in systems for delivering therapeutic nitric oxide (NO) gas to a patient by compensating for drift that may be specific to the sensors atypical use in systems for delivering therapeutic nitric oxide gas to a patient. In at least some instances, the long term sensitivity drift of catalytic type electrochemical gas sensors can be addressed using calibration schedules, which can factor in the absolute change in set dose of NO being delivered to the patient that can drive one or more baseline calibrations. The calibration schedules can be used reduce the amount of times the sensor goes offline. Systems and methods described may factor in actions occurring at the delivery system and/or aspects of the surrounding environment, prior to performing a baseline calibration, and may postpone the calibration and/or rejected using the sensor's output for the calibration.

  • 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.

  • Patent number: 8668380
    Abstract: A method for operating a calorimeter and a calorimeter that is operable to perform the method, wherein the calorimeter has a reactor (1) for receiving a reaction medium, a reactor jacket (2), an in-reactor heater (4) controlled by means of a first controller (6), an outer temperature control unit (9) in thermal contact with the reactor and controlled by a second controller (10), and a measurement sensor (5) arranged in the reactor for determining a reactor temperature (Tr). The reactor temperature is controlled by the heat which is delivered to the reactor by the in-reactor heater and by the heat that is carried in and/or out by the outer temperature control unit. A dynamic control of the heating power of the in-reactor heater and of the outer temperature control unit is used to eliminate any deviation of the reactor temperature from a reactor set-point temperature.

  • Patent number: 8623658
    Abstract: A method of cryopreserving sperm cells which may include cooling the quantity of sperm cells to a holding temperature, maintaining the sperm cells substantially at the holding temperature for a period, and supercooling the sperm cells by cooling the sperm cells at a first cooling rate to a temperature that approaches a critical temperature zone at which ice crystal formation and changes in osmotic pressure damage sperm cells and then cooling the sperm at a second cooling rate faster than said first cooling rate through said critical temperature zone.

  • Patent number: 8617899
    Abstract: A method and device for merging and mixing at least two separate and distinct fluid drops on a substrate, includes a drop merging area on the surface, where a first magnetic material is placed at a first location. A first drop of fluid is then placed at the first location on the surface, resulting in the first magnetic material being at least partially positioned within the first drop of fluid. A second drop of fluid is then placed at a second location on the surface of the drop merging area. A magnetic field is applied by a varying magnetic field generator to at least a portion of the drop merge area of the substrate, which includes at least the first location on the substrate. The varying magnetic field will act on the first magnetic material to move the first magnetic material within the first drop of fluid, causing a stirring of the fluid. A drop merging force from a drop merging mechanism is applied to at least one of the first drop of fluid and the second drop of fluid within the drop merge area.

  • Patent number: 8609429
    Abstract: Methods for determining the fouling propensity of a hydrocarbon stream and for reducing fouling are provided. In one method, the fouling propensity of a hydrocarbon stream is determined by obtaining a parameter value indicative of the fouling propensity at no less than two different temperatures, and an activation energy of fouling by the hydrocarbon stream is derived therefrom. In another method, the thus obtained parameter value at no less than two different temperatures and the activation energy are used to select proper heating fluids and operating temperature and to determine whether to add an antifoulant to the hydrocarbon stream to reduce fouling at a given temperature.
