摘要： A method for determining a pore characteristic of a substance includes the following steps: subjecting the substance to a substantially uniform static magnetic field; applying a magnetic pulse sequence to the substance, the pulse sequence being selected to produce nuclear magnetic resonance signals that are responsive to internal magnetic field inhomogeneities in the pore structure of the substance, and detecting, as measurement signals, nuclear magnetic resonance signals from the substance; applying a reference magnetic pulse sequence to the substance, the reference pulse sequence being selected to produce nuclear magnetic resonance signals that are substantially unresponsive to internal magnetic field inhomogeneities in the pore structure of the substance, and detecting, as reference measurement signals, nuclear magnetic resonance signals from the substance; and determining a pore characteristic of the substance from the measurement signals and the reference measurement signals.

摘要： A device compensating limits of humans senses, includes a receiver receiving information in a first sense, a converter converting the received information into information in a second sense and a presenter that presents the converted information. In an embodiment, the first sense is the vision and the receiver receives visual information comprising texts, wherein the second sense is auditory sense or tactile sensation, and the receiver comprises an ingestion layer that ingests information from a target object. In another embodiment, the receiver ingests the full audio or visual sensory stimuli, and takes the portion that is blocked for the sensory deprivation of the user, and the converter extracts environmental cues contained therein by applying machine intelligence logic and makes trans-sensory conversion to their synthetic representation.
