While carrying out microscope examination, it is possible to specify a position to be irradiated with optical stimulus light and to accurately apply an optical stimulus to the specified irradiation position. The method is predicated upon knowledge of the spectral shape of the signal in the absence of significant noise or spectral deformation. The split ring in this embodiment can have cushions on its ends sized to resist passage through matrix apertures following insertion of such cushions through these apertures when these components are slidably coupled together. If elected, the onboard vehicular system will score a detected driving event, compare the local score to historical values previously stored within the onboard system, and upload selective data or data types to a remote server or user if the system concludes that a serious driving event has occurred. In a cellular phone, judgment is made as to an application, which is an operation target for the user, and, in accordance with the application judged, an input device control section is able to switch between accepting inputs from an electrostatic pad input acceptance section and accepting inputs from a hardware button input acceptance section, depending on the application thus judged by a CPU.
