  • Patent number: 10631722
    Abstract: A probability distribution of visual sensitivities at each visual target presentation position of the subject is inferred on the basis of the test result information which is visual sensitivity information at each of the visual target presentation positions obtained through the tests performed in the past. Input of visual sensitivity information of the subject at at least one presentation position among the plurality of visual target presentation positions is received. Mutual information between visual sensitivity information of the subject regarding the visual test target represented by the received information and visual sensitivity information regarding each visual test target for which no visual sensitivity information of subject has been input, using the inferred probability distribution, is calculated, and the calculated mutual information is provided for a predetermined process for selecting a position at which the next visual test target is to be presented.

  • Publication number: 20190362919
    Abstract: A pressure switch includes an airtight metallic pressure vessel. A contact mechanism is normally in a closed state and assumes an open state when a pressing force acts thereon. An airtight terminal, provided through an end surface section of the pressure vessel, is connected to the contact mechanism. A metallic first diaphragm is secured to a surface section at one end of the pressure vessel, is moved by a first moving pressure, and is reset by a reset pressure that is lower than the first moving pressure. A first plunger causes the contact mechanism to switch the open state. A metallic second diaphragm is secured to pressure vessel, is moved by a second moving pressure that is higher than the first moving pressure, and is not reset under at least an atmospheric pressure. A second plunger causes the contact mechanism to switch to the open state.
