  • Patent number: 10714052
    Abstract: A display device includes a display unit and a controller. The display unit displays an image thereon. The controller is capable of, when the image is displayed as being moved, controlling the display unit to execute moving-manner correction processing in which pixels forming the image to be moved are displayed in display colors determined by corrected R, G, and B values obtained by adding RGB correction values to color component values provided as R, G, and B values that indicate red, green, and blue color components of respective display colors of corresponding pixels forming the image while the image has been stopped. Each of the RGB correction values has been previously determined in common for the color component values of a corresponding display color.

  • Patent number: 10583398
    Abstract: According to the present invention, since a pretreatment mechanism can be operated while inhibiting the pretreated water from fluctuating in pressure, a fresh-water production apparatus is obtained in which the desalting mechanism can be stably operated. Furthermore, the period of water supply or flushing in the step of washing the pretreatment mechanism can be shortened, and the load on the lines where washing is not being performed is hence reduced. Consequently, a fresh-water production apparatus is obtained in which the pretreatment mechanism can be operated while inhibiting the pretreatment membranes from being fouled.

  • Publication number: 20190101631
    Abstract: A time-of-flight imaging system may output light with a modulation frequency in the gigahertz band, to illuminate a range target. This high-frequency illumination may enable extremely precise—e.g., micron-scale—depth measurements. The system may modulate reflected light from the range target, to create a beat tone that has a frequency in the hertz band. In some cases, the modulated light in the gigahertz band is created by a first modulator and the beat tone in the hertz band is created by a second modulator. In some cases, the modulated light in the gigahertz band is created by an upshift cascade of modulators and the beat tone in the hertz band is created by a downshift cascade of modulators. A photodetector may measure the low-frequency beat tone. From this beat tone, phase of the signal and depth of the range target may be extracted.

  • Patent number: 9863726
    Abstract: A cooling medium circulating apparatus includes first and second flow paths configured to circulate a cooling medium, and a flow path switchover unit for connecting or disconnecting between the first and second flow paths. A method for controlling a cooling medium circulating apparatus includes detecting temperatures of the cooling medium flowing through the flow paths. The method further includes calculating a temperature difference between temperatures of the cooling medium flowing through the first and second flow paths. In the cooling medium circulating apparatus and method, a prescribed cycle is set, and connecting and disconnecting periods are set. The connecting and disconnecting periods are periods for connecting and disconnecting, respectively, between the flow paths in the prescribed cycle. The flow path switchover unit is controlled based on the connecting and disconnecting periods. The prescribed cycle becomes shorter as the temperature difference becomes larger.
