  • 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: 20140362887
    Abstract: A differential on-chip temperature sensor circuit can be implemented in a standard complementary metal-oxide-semiconductor (CMOS) process using PNP transistors. A pair of transistors have collector currents that are sensitive to voltage, both directly and due to saturation currents. A scaling resistor connects to the emitter of one transistor and its voltage compared to the other transistor's emitter voltage by an error amplifier that generates a bias voltage to current sources that are proportional to absolute temperature since the saturation current sensitivity is subtracted out. The current is mirrored to sink current through a multiplier resistor from an output. An amplifier connected across the multiplier resistor compares a reference voltage to set the DC bias independent of temperature sensitivity. The temperature sensitivity is proportional to the ratio of the multiplier resistor and the scaling resistor, and is multiplied by a mirroring factor. A differential output is provided.

    Abstract: Mobile devices are re-supplied with fluids on a periodic basis thereby eliminating the need to maintain a permanent connection between an external fluid supply and the moving device. Electronic scanning devices generate heat and operate at varying and high temperature conditions that interfere with operations of the scanner heads. Circulating a heat transfer fluid through the sensor head removes excess heat from heat sensitive regions of the sensor head during operations. Once the heat transfer fluid reaches a predetermined temperature or after passage of a predetermined length of time, the scanner head is maneuvered to a docking station where it is coupled to an external heat fluid source where fresh fluid is supplied to the scanner head.

  • Patent number: 8350571
    Abstract: An electronic salt meter including a sensor rod, salt meter body and receiving components to measure a temperature and salinity. The electronic salt meter includes a first and sensor electrode and a temperature sensor to detect a temperature of the measurement object. A measurement monitoring unit detects whether the first and second sensor electrodes are electrically connected to each other. A salinity measurement unit applies an AC power to the first and second sensor electrodes to measure salinity of the measurement object. A temperature measurement unit applies a power to the temperature sensor to measure the temperature of the measurement object. A thermal equilibrium detection unit stores the temperature value previously measured, and when the temperature variation is less than a predetermined threshold, it is determined as a thermal equilibrium state. A room-temperature salinity conversion unit converts the salinity value into a salinity value at room temperature.

  • Publication number: 20120177081
    Abstract: Embodiments validate cryogenic processing of metal-matrix validation articles according to destructive and/or non-destructive testing of witness articles. For example, validation can certify that the validation article has undergone a particular cryogenic treatment protocol, resulting in validated and/or certified enhancements in wear characteristics, resistance to corrosion, increases in electrochemical bonding of surface treatments, increases in theoretical useable lifespan, etc. According to some embodiments, processing results are validated by generating witness results from destructive and/or non-destructive testing of the witness articles subsequent to deep-cryogenic treatment. The processing (e.g., including witness results and/or analysis thereof) may then be entered into a computer-controlled, parametric analysis system that generates absolute and comparative validation and/or certification of the validation articles.

  • Patent number: 8066429
    Abstract: A thermal measurement apparatus and method for performing heat flux differential scanning calorimetry (DSC) is disclosed. A variable thermal resistor is used to couple a measurement assembly to a heat sink in the thermal measurement apparatus, such that samples can be rapidly heated and rapidly cooled. The apparatus can be configured with a highly conductive sample assembly enclosure. The enclosure can include a high emissivity coating. In one embodiment, the enclosure extends along a longitudinal direction that is about the same as that of an infrared lamp assembly used to heat the enclosure, thereby increasing the efficiency of heating the sample enclosure. In one configuration, the variable thermal resistor comprises a gap whose gas composition can be varied during a sample measurement to independently optimize sample heating and cooling rates.
