Abstract: A cell culturing device includes: a sensor that measures a pH of a medium in which cells are being cultured; and one or more processors including hardware. The one or more processors are configured to: measure an elapsed time since the cells were seeded in the medium; determine whether the measured pH is lower than a prescribed threshold and whether the measured elapsed time has passed a prescribed time; and issue an instruction for medium replacement in response to determining that the pH is lower than the prescribed threshold or in response to determining that the elapsed time has passed the prescribed time.

Abstract: An observation system includes an illumination unit including a light source from which emits an illumination light including light of a plurality of colors, and light receiving unit including an optical sensor which acquires a light intensity. The illumination unit emits the illumination light for a culture vessel so that the illumination light travels from a first side to a second side of the culture vessel, the first side and the second side being defined by interposing a culture medium. The light receiving unit receives, on the first side, light emitted from the illumination unit, entering the culture vessel from the first side, reflected at the second side, and transmitted through the culture medium, and acquires a light intensity for each color in the received light for calculation of a pH value of the culture medium.

Abstract: A quantitative evaluation apparatus of the present invention includes: a counter that counts the numbers of cells or densities of cells contained in individual images of a plurality of image-capturing regions in a culturing vessel for culturing the cells; an evaluation-value calculating portion that calculates an evaluation value related to variation in the distribution of the cells in the culturing vessel on the basis of the numbers of the cells or the densities of cells counted by means of the counter in each of the images; a determining portion that determines whether or not the evaluation value calculated by the evaluation-value calculating portion is in a range of a prescribed threshold; and a display that displays determination result determined by the determining portion.

Abstract: A medium changing device includes a lid disposed at a position where two or more regions in which a medium may be stored are covered therewith, the regions being disposed adjacent to each other and being open upward; one or more flow-path members each disposed so as to penetrate the lid, and each disposed at a position where one of the regions is bridged to another therewith when the lid is disposed at the position where the regions are covered; and a pump disposed on the other side of the lid and acting on the intermediate sections of the flow-path members, exposed on the other side, so as to cause the medium to flow from the opening at one end toward the opening at the other end of each of the flow-path members.

Abstract: In a focus adjustment method for an imaging apparatus, that, in order to focus on a single or a plurality of point light sources, acquires plurality of image data while moving a focus lens in an optical axis direction and carries out focus adjustment based on the image data, brightness values of pixels within a given evaluation region are detected based on the image data, high brightness evaluation values are calculated based on the brightness values, symmetry of the high brightness evaluation values are calculated for movement of the focus lens, and focus adjustment is carried out based on an extreme value calculated based on the symmetry.

Abstract: A motion detection apparatus includes an inertia motion detection section which detects an inertia motion of an object to be measured by using at least one of an acceleration sensor or an angular velocity sensor. An image pickup section which picks up a peripheral image of the object to be measured. An image comparison section which compares images picked up at different points in time by the image pickup section. A camera position and posture acquiring section which detects a position and a posture of the object to be measured by using a result of comparing the images by the image comparison section. A spatial position and posture acquiring section which detects a position and a posture in space of the object to be measured on the basis of information obtained by the inertia motion detection section and the camera position and posture acquiring section.

Abstract: A movement detection device includes a self-sustaining movement detection unit which is attached to an operator's body and detects a movement or a posture of an attached part of the operator's body. An image pickup section picks up a projected image from an optical system which simultaneously inputs a peripheral image. An image conversion section converts an all azimuth image picked up by the image pickup section into a cylindrical panorama image. An image recognition section includes cylindrical panorama images at different times. A camera posture estimation section acquires movement information of the image pickup section based on a comparison result of the image recognition section. A space sensor posture estimation section acquires a position/posture of the attached part in a space based on information of the self-sustaining movement detection unit and the camera posture estimation section.

Abstract: An operation input device includes a back-of-hand detection section, spatial coordinate computation section, finger posture detection section, finger shape estimation section, hand shape estimation section, and operation input analysis section. The back-of-hand detection section is mounted on the back of the hand of an operator to detect the motion or posture of the back of the hand. The spatial coordinate computation section obtains the position or posture of the back of the hand in a three-dimensional coordinate system on the basis of an output from the back-of-hand detection section. The finger posture detection section is mounted near the tip of a finger of the operator to detect the posture of the finger. The finger shape estimation section computes the posture of the finger with respect to the back of the hand of the operator from an output from the finger posture detection section by using an output from the spatial coordinate computation section.

A projection optical system projects the image displayed on the two-dimensional display unit onto the retina of the eyeball of a user. A shutter is arranged in front of the eyeball of the user. A detector detects at least a forward inclination of motions of the head portion of the user. A control unit controls the shutter in accordance with the output from the detector to switch the shutter between a light transmission state and a light shielding state. A housing incorporates and holds the two-dimensional display unit, the projection optical system, the shutter, and the detector to be mountable on the head portion of the user.
