Abstract: A system for generating a series of reducing intensity laser pulses from an ultrafast pulsed laser source. The reducing intensity series of pulses is equally temporally spaced between pulses from the laser source. The repeating series of reducing intensity laser pulses is fed to a microscope for imaging. The microscope is capable of detecting the fluorescence from a sample generated by each pulse in the series. The data is processed using knowledge of the pulse intensity, location on the test sample, and amount of fluorescence measured to create an increased dynamic range of the image relative to what can be obtained in a normal two-photon imaging system.

Abstract: In a door mirror device for a vehicle, when a driving body is moved rotationally towards an upper side, a gear plate is moved towards a lower side so that urging force applied from a coil spring to the driving body is decreased. In contrast, when the driving body is moved rotationally towards the lower side, the gear plate is moved towards the upper side so that the urging force applied from the coil spring to the driving body is increased. As a result, it is possible to reduce a difference between a load that is applied in order to move the driving body rotationally towards the upper side and the load that is applied in order to move the driving body rotationally towards the lower side.

Abstract: Adjusting instrument for an exterior vision unit for a vehicle, comprising a base, a foot and a pivoting shaft extending therefrom along a longitudinal axis, and a housing surrounding the pivoting shaft and pivotable around the longitudinal axis in an adjustment range, between at least a park position and a work position.
