  • Patent number: 8981947
    Abstract: There is provided a water quality monitoring apparatus including: an air quality analyzing unit detecting, using an ion mobility sensor, air quality in a space that is at least partially enclosed by a partition wall and a boundary surface with water whose water quality is to be monitored; and an alarm unit that outputs a signal indicating an abnormality if an air quality pattern obtained by the air quality analyzing unit is outside a tolerated range for air quality patterns of air that contacts the water to be monitored. Such water quality monitoring apparatus is capable of monitoring the water quality of drinking water inside a water tank or the like indirectly but precisely by detecting the quality of the air contacting the water using an ion mobility sensor.
    Type: Grant

  • Patent number: 7613931
    Abstract: The present invention relates to a programmable-gate-array copy protection method and a system which prevent unauthorized copying of an FPGA program. A copy protection method for a field-programmable gate array, the method comprising a step of causing a user-specific gate array to boot a user circuit data to the field-programmable gate array, the user-specific gate array being connected to the field-programmable gate array and a memory device in which the user circuit data is stored and being pre-programmed at a semiconductor-vender's factory.
