  • Publication number: 20210166575
    Abstract: A pseudo-food texture presentation device includes: an enclosure body in which a granular material is enclosed; a measurer configured to measure at least one index among a temperature of an ambient environment of the enclosure body, a humidity of the ambient environment of the enclosure body, a temperature of the enclosure body, and a moisture amount on a surface of the enclosure body; and an enclosure body controller configured to control density of the granular material inside the enclosure body in accordance with the measured index.

  • Publication number: 20200402418
    Abstract: The number n of times of chewing is counted by chewing number of times calculation means (13b2) based on a change in the distance l from a photorefiector (50), which is received together with time t by measurement value receiving means (13b1). To vary hardness h of a bag (30) to a stage that can be sensed, according to the number n of times of chewing, a required air pressure is set according to the current number n of times, based on a hardness/air pressure correspondence recording unit (13g) in which stages that have a significant difference therebetween and are stored in association with the number n of times of chewing are recorded. To realize the set air pressure inside the bag (30), the amount of sucking performed using a vacuum pump 20 is controlled by air pressure control means (13b4).

  • Patent number: 10338462
    Abstract: An aerial image display device is capable of changing a depth of a virtual image viewed by an observer without changing a distance between at least one display device and an optical element forming the virtual image. The aerial image display device includes a display device, optical elements, and a reflecting member. The optical elements are installed corresponding to different display regions of a display surface of the display device and sequentially arranged along the display surface in an observation direction of an observer. The optical element is installed obliquely with an angle of about 45° in a ?X direction when viewed from the display surface of the display device. The optical element is installed obliquely with an angle of about 45° in an X direction when viewed from the display surface of the display device.
