Abstract: A prediction device includes a state detector that detects a state related to sleepiness of a driver; an eye-closure duration detector that detects an eye-closure duration of the driver; and a microsleep predictor that predicts that the driver is in the microsleep state, on conditions that the state detector detects the state related to the sleepiness of the driver and that the eye-closure duration detector detects the eye-closure duration that is no shorter than a first duration and no longer than a second duration.

Abstract: A visual line measuring device of the present disclosure includes a light source that emits light for forming a corneal reflection point on an eyeball of an object person who gazes at a predetermined gaze point, an image-capturing part that captures a plurality of facial images each of which includes the eyeball of the object person by which the light from the light source is reflected, a detector that calculates visual line information for each of the facial images captured by the image-capturing part, a calculation part that calculates correction information by using at least two sets of the visual line information being in a predetermined positional relation among a plurality of sets of the visual line information calculated by the detector, and a correction part that corrects the visual line information calculated by the detector, by using the correction information.

Abstract: An eye tracking method in the disclosure comprises an image-capturing step of capturing a facial image including an eyeball of an object person, light from a light source that emits the light to form a corneal reflex point on the eyeball of the object person who gazes at a predetermined gaze point being reflected from the eyeball, a detecting step of calculating visual line information in a world coordinate system using the facial image captured in the image-capturing step and a correcting step of transforming the visual line information in the world coordinate system calculated in the detecting step into visual line information in a correction coordinate system that is a coordinate system different from the world coordinate system, and correcting the visual line information in the correction coordinate system using correction information for correcting a detection error caused by an individual difference of the eyeball.

Abstract: A largest page size obtaining unit obtains a largest page size of a printed matter based on manuscript data. A RIP processing unit generates a page image in a bitmap format for each page based on the manuscript data. A position determining unit determines a position within a reference page having the largest page size for each page based on the manuscript data. A display image generating unit generates a display image including a page image of a spread page by arranging the page image to be displayed at the position determined by the position determining unit. A display unit displays the generated display image. With this, there is provided an image display device which correctly displays the printed matter including pages of different sizes.

Abstract: An information notification method includes obtaining a parking time limit during which a user is allowed to continuously park a vehicle at a parking lot, measuring a travel time required for the user to move from the parking lot to a destination, obtaining a round trip time required for the user to make a round trip between the destination and the parking lot, calculating a remaining time during which the user is allowed to stay at the destination by subtracting, from the parking time limit, the round trip time and an elapsed time measured from when the user has reached the destination, determining whether the remaining time is less than or equal to a threshold value preset to zero or greater, and notifying the user that the remaining time is short if it is determined that the remaining time is less than or equal to the threshold value.

Abstract: A preflight check unit in a printing control apparatus includes a sub-preflight check unit, an object page determination unit, a main preflight check unit, and a preflight result output unit. The sub-preflight check unit obtains resource use information and part use information. The object page determination unit determines object pages to be subjected to the preflight check, based on the resource use information and the part use information, and writes object page information indicating the object pages in a storage unit. The main preflight check unit reads the object page information from the storage unit to perform preflight check on the object pages indicated by the object page information. The preflight result output unit outputs a preflight result.

Abstract: This disk loading device is capable of reproducing a plurality of disks. A power transmission to drive gears is switched by tooth omission gears of a control gear so that angular movement of a disk playing portion, as well as movement of a tray base in a non-reproducing position and a reproducing position of the disk playing portion, can be effected by a single motor. A close lock gear, which prevents movement of the tray base in a disk reception stop positions, limits position of the drive gears. With this arrangement, when each tooth omission gear of the control gear enters the teeth of the corresponding drive gear, the interference of the teeth is eliminated. With this construction, the number of component parts such as a drive motor is reduced, thereby achieving a compact design and a stable operation.

Abstract: The rotary motion of a driving cam driven by a driving motor is converted into both the upward and downward movement of a deck member and the forward and backward movement of a tray, so that the deck member and the tray can be driven by a single motor. Further, the conversion into the upward and downward movement of the deck member and the forward and backward movement of the tray is performed by the engagement of a pin of the driving cam with a straight groove and a circular groove of a driving lever. Since the straight groove is extended in the tangential direction of the driving cam, when the pin engages with the straight groove, the driving lever receive a force to slow down the opening and closing speed of the tray at the beginning and end of the movement, thereby improving the quality of the loading operation.

Abstract: A disc changer for sequentially playing back a plurality of discs such as compact discs has a circular tray rotatably mounted on a base for supporting a plurality of discs replacably mounted on a horizontal surface. A drive mechanism rotates the tray and stops the tray to position one of the discs in a playback position. A recorded signal is reproduced from the disc in the playback position by a pickup. The pickup is vertically moved and stopped in a predetermined vertical position by a lifting/lowering mechanism. A pickup cover is disposed over the tray in covering relation to the pickup and the disc in the playback position. The disc changer also has a dust cover hinged to the base, for covering at least the tray, the dust cover having a transparent window extending over the tray.
