  • Patent number: 11961059
    Abstract: The present disclosure promotes distribution of sensor data among a plurality of business operators. A controller that an information processing system according to the present disclosure includes collects first data including a plurality of items and personal information from mobile bodies belonging to a first business operator. The controller converts the first data to second data not being usable to identify individuals. The controller provides data in a range decided based on content of a predetermined data use contract, among the second data, to a second business operator. The controller calculates a consideration for the data that is to be paid by the second business operator, based on a data use record of the second business operator.

  • Patent number: 6080172
    Abstract: A corneum layer stabbing device of the present invention frees a patient or subject from physical and psychological pains and realizes rapid curing. After a casing has been positioned on a skin, an electromagnet is energized to move a needle or needles mounted on a shaft until they stab the skin and penetrate a corneum layer. When the electromagnet is deenergized, the shaft returns to its original position due to the action of a spring, moving the needles away from the skin. As a result, holes are formed in the corneum layer of the skin.

  • Patent number: 5961799
    Abstract: In a liquid component measuring apparatus including a measuring cell (11) which measures a specific component of a predetermined amount of liquid sample by diluting, as diluted liquid sample, the predetermined amount of liquid sample with a buffer solution having a pH buffer capacity and a support electrolyte, the measuring cell includes a metering section (12) having an upper part tapered upward and having a metering space therein. A sample injection port (19) is formed at a top of the upper part. A buffer injection port (18) supplies the buffer solution to the metering space so that the metering space is completely filled with the buffer solution.

  • Patent number: 5782871
    Abstract: A sampling device of the suction effusion fluid that is good in sampling operation efficiency. This device includes a cell with a vacuum suction port and a skin suction port, a slide valve formed in the cell, and fluid reservoirs formed in the valve. The slide valve is movable in a plane approximately parallel to the skin surface. The slide valve opens or closes a communication path communicating the skin suction port with the vacuum suction port. Each of the fluid reservoirs is alternately communicated with the skin suction port and the vacuum suction port through the communication path by sliding movement of the slide valve. Each of the fluid reservoirs stores an effusion fluid acquired from the skin surface by vacuum suction through the skin suction port. When the slide valve is located at a position where one of the fluid reservoirs is communicated with the skin suction port and the vacuum suction port, at least one of the remaining fluid reservoirs is exposed to the outside of the cell.

  • Patent number: 5762640
    Abstract: A device for sucking an effusion fluid from the skin of an organism from which keratin has been removed. A disk is received in the cavity of a cell for sucking an effusion fluid in contact with the surface of an organism. Guide grooves are formed in the surface of the disk facing a suction port while holes are formed through the disk in each guide groove. The disk allows a minimum of fluid to remain thereon and guides the fluid toward the suction side in order to enhance efficient collection. When the fluid is collected a plurality of times, the preceding fluid and the following fluid are prevented from being mixed together, insuring accurate measurement.
