A headphone apparatus the acoustic characteristics of which can be easily changed in accordance with the type of content the user wants to listen to. An adjusting knob provided on the housing of the headphone apparatus is moved, closing an opening made in a baffle. As a result, an acoustic space defined by the inner side of the baffle and an ear pad is more closed, thus increasing the level of low-frequency components of the sound generated by a sound-generating unit. Hence, the acoustic characteristics of the apparatus can be easily changed as the user desires.

For each color match candidate location, a region proximal to the location may then be searched in detail, based on pattern information obtained in a pattern analysis of the template image.

A multispectral nevoscope that uses specific wavelengths in the visible and infrared spectrum of electromagnetic radiation to transilluminate a skin-lesion or a biological tissue or specimen for imaging and maps multispectral 2-dimensional images into 3-dimensional virtual space for providing 3-D distributions of pre-defined parameters representing the characteristic properties (such as melanin, hemoglobin and deoxyhemoglobin, etc.) of a skin lesion. Methods are disclosed for analyzing and using the characteristic distributions of specific parameters for detection and management of skin-cancers, or characterization of a biological tissue or specimen.

A polarization lidar system capable of remotely identifying characteristics of atmospheric aerosol particles by transmitting a polarized beam of light and analyzing polarization characteristics of received backscatter is disclosed. The transmitter features high pulse energy to remotely identify aerosol particles with substantially one pulse. The transmitter employs a thin film plate polarizer and a Raman wavelength shifter to achieve eye-safe, single-plane linearly polarized energy. The transmit beam and receiver field of view are coaxial. The receiver employs a telescope, a collimating lens, and a beam splitter. The beam splitter splits the received backscatter into a single-plane polarized beam whose polarization plane is parallel to the plane of transmission and a single-plane polarized beam whose polarization plane is perpendicular to the plane of transmission. Each split beam is directed through separate focusing lenses onto separate detectors. The detector signals are amplified and processed to remotely determine atmospheric aerosol particle characteristics.

Empirically derived models are used to relate user perception to objectively measurable characteristics, under a criterion of nearly perfect co-variance between predicted MOS values and the variations in the values of the objectively measurable characteristics. In the example context of evaluating packet switched telephony service, the present invention eliminates the need to perform subjective tests to characterize each combination of codec type and transmission protocol.

A method and system of monitoring the movement of at least one front in an inter-well region is comprised of: providing a first well representing the origination of at least one front (such as a saturation front or a salinity front); providing one or more monitoring locations, each equipped with at least one sensor; and monitoring the arrival of at least one front at one or more monitoring locations.

Embodiments of systems, computer-implemented methods, and non-transitory computer-readable medium having one or more computer programs stored therein are provided to enhance borehole image analysis associated with a hydrocarbon reservoir. A neural network mapping process can first be performed, responsive to openhole log data and core data, to thereby generate a material-type scheme. Then, an image-based petrophysical analysis process can distribute and calibrate borehole image data, responsive to the core data and material-type scheme. Consequently, an approximated material type and an approximated grain size can be produced for each borehole image reading. The openhole log data, the core data, the material-type scheme, and the approximated material types and grain sizes, for example, can then be displayed to thereby increase consistency in categorizing subsurface material associated with hydrocarbon wells by material type and enhance interpretation of subsurface material texture, fabric, and features to predict subsurface material composition of the hydrocarbon reservoir.
