  • Publication number: 20220255641
    Abstract: In the measurement device 1, a reception sensitivity test control unit 18 ends throughput measurement of a CC using a throughput measurement unit 18b in a case where an end determination unit 18c1 determines that any of a plurality of CCs has reached a measurement end condition, and calculates a total status obtained by integrating a determination result for each CC using a total status calculation unit 18c2 by performing each “PASS” or “FAIL” determination for a remaining CC. Since an output level variable setting unit 18d performs a process of setting a next output level for the CC that has not reached the measurement end condition based on the total status, a control is performed to continue a reception sensitivity test until all CCs reach a measurement end condition.

  • Publication number: 20220239388
    Abstract: Provided are a mobile terminal test apparatus, a mobile terminal test system, and a control method for the mobile terminal test apparatus, which can reduce burdens on a user for setting parameters according to a specification of a test. A setting screen is displayed with a first operation image 21 for selecting a specification of a test and a second operation image 22 in which parameter operation images 22a to 22e for setting parameters for executing the test according to the specification selected by an operation with respect to the first operation image 21 are arranged based on parameter hierarchies. With an operation of changing one parameter with respect to the parameter operation images 22a to 22e, lower parameter operation images whose parameter hierarchies are lower than the parameter operation image are updated according to the specification selected by the operation with respect to the first operation image 21.

  • Patent number: 11270473
    Abstract: In an operation management system in the related art, it is necessary to add an identification mark such as an RFID tag to each component to be managed and prepare a fastening tool having an antenna. In contrast, a mechanical fastening unit management method is provided using an augmented reality space generated by superimposing a virtual space on a real space. In the augmented reality space where a real fastening unit (RBn) and a virtual fastening unit (IBn) are in a one-to-one correspondence, information that the real fastening unit is selected as a fastening target is acquired with a camera or the like, and analyzed by an augmented reality server connected to the camera. Accordingly, it is possible to easily record that a predetermined operation is progressing as scheduled, and to provide a high quality mechanical fastening unit management method or system that is low in operation cost.
