  • Patent number: 11965921
    Abstract: A measurement system and method tests for spurious emissions included in a signal transmitted from a mobile terminal in a shorter time than before. The system includes: a band division unit for dividing the measurement frequency band into a plurality of divided bands; a first spurious measurement control unit which causes a measurement device to measure the spurious emissions of the signal to be measured in each divided band and the peak power of the spear in each divided band; and a first pass/fail determination unit that determines whether or not pass determination criteria is satisfied. The first pass/fail determination unit determines whether the peak power does not exceed the threshold of the pass determination criteria in each divided band. The threshold value of the pass determination criteria is lower than the threshold of the standard determination criteria defined by the 3GPP standard.

  • Patent number: 10859028
    Abstract: Disclosed is a fuel injection control device for an engine equipped with a solenoid-type fuel injector 67. The fuel injection control device comprises: a voltage sensor SW19 configured to detect a voltage of a solenoid of the fuel injector 67; and a PCM 10 configured to set a valve-open period of the fuel injector 67, based on a fuel injection amount according to an operation state of the engine 1, and control the fuel injector 67 based on the valve-open period. The PCM 10 is configured to perform correction for gradually shortening the set valve-open period, as the voltage (residual voltage) detected by the voltage sensor SW19 when opening the fuel injector becomes larger, and control the fuel injector 67 based on the corrected valve-open period.
