    摘要: The sensor has four electrodes arranged on a common base, three of which are made as closed circuits, placed one into another, whereas the fourth electrode is placed inside the smallest circuit. The external and the central electrodes form a pair of current-feeding electrodes, whereas the electrodes disposed between them form a pair of measuring electrodes. The second design option of the sensor has three electrodes, two of which are made as closed circuits placed one into another, whereas the third electrode is placed inside the electrode that is smaller. The external and the central electrodes form a pair of current-feeding electrodes, and the electrode arranged between them together with the external or the central electrode form a pair of measuring electrodes. The design of sensors makes it possible to use them in combination with biological signal sensors of non-rheographic modality, for example, pulse wave, temperature. The sensor may be incorporated in wristwatch or bracelet.

    摘要: A method of non-invasive determination of a glucose concentration in blood based on the measurements of the total impedance of the skin of a patient is disclosed. The method is based on a linear model of a first order correlation between the glucose concentration and the total impedance, the model taking into account the rate of change of the glucose concentration. The coefficients used in an approximating function are determined at the preliminary stage measurements by an invasive method.

    摘要: A method of and apparatus for separation from a stack of sheets a block of a predetermined number of sheets, the method including moving the stack in a forward direction, directing an air stream across one corner of the forward portion of the stack to spread the corners apart, sensing and counting the number of spread sheet corners that pass a predetermined location, and separating the group of sheets from the remainder of the stack when the sensed and counted sheets reach a predetermined number. Further directing a thin plane of air toward the corner and center of the sheets at said location to cause a greater space between the sheets in the group and the next sheet in the stack. Also, vacuum nozzles are provided to remove unwanted air from above and below the stack and group. With the group so formed, separation includes imparting lateral force on the group edges.
