  • Patent number: 9643737
    Abstract: Method, apparatus, and computer program product for providing a cause of a scent and/or sound detected during operation of a vehicle are provided. In the event a vehicle operator hears a sound or smells a scent while operating a vehicle, a microphone can sample the sound and/or an electronic nose can sample the scent. A sound and/or scent profile is generated from the sampled sound and/or sampled scent. The generated sound and/or scent profile are compared to known sound and/or scent profiles stored in a data structure. In the event the generated sound and/or scent profile matches a known sound and/or scent profile, the data structure is checked for correspondences between the matched, known sound and/or scent profile and a cause of the sound and/or scent. In the event a correspondence to a cause exists, then the cause is output to a user to identify the cause of the sound and/or scent.

  • Patent number: 9412558
    Abstract: A method for performing high resolution electron microscopy of a soft matter object is described. The method comprises irradiating a soft matter object using an electron microscope having a spherical aberration correction with a substantially constant transfer function in a frequency band of thermal diffuse scattered electrons scattered at the soft matter object. The method comprises detecting the thermal diffuse scattered (TDS) electrons scattered at the soft matter, and using the detected thermal diffuse scattered electrons for deriving therefrom an image of the soft matter object.

  • Patent number: 9366677
    Abstract: In a first aspect, provided herein is a method of determining assembly, homogeneity and/or thermodynamic stability of biological macromolecular complexes. In particular, the method allows determining maximum stability of the complexes based on fluorescence changes at an appropriate wavelength as a function of temperature whereby the fluorescence changes reflect the status of assembly, homogeneity and/or thermodynamic stability of the biological macromolecular complexes. The method is based on identifying two state and multistate unfolding fluorescence curves as a function of temperature by fitting the curves according to a multistate unfolding model. In addition, a computer program and a computer program storage medium as well as an apparatus and a system is provided for determining the assembly, homogeneity and/or thermodynamic stability of biological macromolecular complexes.
