  • Patent number: 10254538
    Abstract: The present invention is intended to provide an adaptive optics system and an optical device that allow correction of wavefront phase aberration with higher accuracy than before and have a wider correction range than the conventional ones, regardless of the distance between the observation target and the fluctuation layer, and the size of the observation target. An adaptive optics system includes: a wavefront phase modulator that makes aberration correction to incident light and emits the corrected light; and an imaging-conjugated position adjustment mechanism that adjusts freely within a specimen the position of a surface imaging-conjugated with a fluctuation correction surface formed by the wavefront phase modulator. The imaging-conjugated position adjustment mechanism adjusts the fluctuation correction surface to be imaging-conjugated with a fluctuation layer existing in the specimen.

  • Patent number: 10060329
    Abstract: A vehicle has a front grille, engine, engine compartment, power storage device, temperature sensor, shutter, heater and controller. The device can be electrically charged from an external power supply. The temperature sensor detects engine coolant temperature. The shutter is disposed in a transfer pathway of air drawn into the engine compartment via the front grille, and is switched between closed and open states. The heater is able to generate heat when receiving the electric power, raising the coolant temperature. The controller starts the engine when the coolant temperature is lower than a startup threshold value, drives the heater when the coolant temperature is lower than a first threshold value equal to or higher than the startup threshold value, until the coolant temperature becomes equal to or higher than the first threshold value, and drives the shutter to place the shutter in the closed state while the heater is driven.
