Abstract: A photodetection device according to the present disclosure includes: a light-receiving section including a light-receiving element, a first switch, a second switch, and a signal generator, the first switch that couples the light-receiving element to a first node by being turned on, the second switch that applies a predetermined voltage to the first node by being turned on, and the signal generator that generates a pulse signal on the basis of a voltage at the first node; a controller that controls operations of the first switch and the second switch; a detector that detects a timing at which the pulse signal is changed, on the basis of the pulse signal; and an output section that outputs a detection signal corresponding to a detection result by the detector when the second switch is turned on.

Abstract: An aircraft includes a fuselage including a plurality of frame members disposed at predetermined intervals in a longitudinal direction of the fuselage and a plurality of stringers extending substantially linearly in the longitudinal direction. The fuselage defines an aircraft interior. A compartment is located in the interior of the fuselage. The compartment defines an interior area. A first window assembly is mounted to an upper portion of the fuselage for introducing daylight into the interior area. The first window assembly is flanked by adjacent frame members of the plurality of frame members and adjacent stringers of the plurality of stringers. The first window assembly includes a window pane, an inner cover and a retainer. The inner cover introduces daylight from the window pane into the interior area. The retainer secures the window pane and the inner cover to the fuselage.
