Abstract: The invention relates to a spectrum scanning assembly and an optical semiconductor element. The spectrum scanning assembly includes a band-pass waveguide assembly and multiple micro-ring resonators, and the band-pass waveguide assembly is respectively connected to the multiple micro-ring resonators; in which: the band-pass waveguide assembly is used to divide an optical signal to be tested into multiple band-pass optical signals with different central wavelengths and then respectively input into the multiple micro-ring resonators; each micro-ring resonator is used to perform scanning for resonant wavelengths in the band-pass optical signals to form first spectral information; in which after beam combination is performed on multiple pieces of first spectral information formed by the multiple micro-ring resonators, second spectral information may be formed. The spectrum scanning assembly and the optical semiconductor element of the invention have high spectral scanning precision.

Abstract: A smartphone includes a communication I/F that communicates with a target device, a first setting unit that sets a first communication condition that is a condition for transition of the communication I/F from an active state communicating with the target device to a dormant state that does not communicate with the target device, an acquisition unit that acquires from the target device a second communication condition that is a condition of transition from an active state communicating with the communication I/F to a dormant state that does not communicate with the communication I/F, and a display control unit that controls a touch panel, and when the first setting unit receives a first change operation that makes difficult for the communication I/F to transition from the active state to the dormant state, the display control unit causes information indicating the second communication condition to be displayed on the touch panel.

Abstract: The pulse width of light from a pulsed light source 1 is stretched by a stretching element 2 such that an elapsed time and the wavelength of the light in the pulsed light correspond to each other on a one-to-one basis, and the stretched light radiates to an object S. The output of a light receiver 4 that has received light from the object S is digitized by an AD converter 6 and the digitized signal is supplied to a calculation means 5. A trigger signal generated by a trigger signal generator 7 in response to the rise of the pulsed light is delayed by a trigger delay section 74 and supplied to the AD converter 6 after the completion of a dead time T3.
