An appearance inspection apparatus radiates, with an illumination device, light from a light source as diffused light to an inspection surface included in the inner peripheral surface of an inner ring of a rolling bearing that is an object to be inspected, and photographs the inspection surface with a camera. The illumination device is arranged so that at least a part of the illumination device is present in a space surrounded by the inner peripheral surface of the rolling bearing. The camera is arranged at a position where an angle formed between a straight line connecting a position closest to the camera on the inspection surface to the camera and a line perpendicular to the inspection surface at that position is larger than an incident angle of the diffused light at the position closest to the camera.

A multi-view-angle image capturing device for capturing surface images of a object comprising a pickup device, an image augmentation module, an image capturing device, and an inspection device. The pickup device loads the object to an inspection position. The image augmentation module is configured around the inspection position so as to reflect different view angle images of the object. The image capturing device is positioned at the inspection position and captures images of the object and images reflected by the image augmentation module so as to obtain a plurality of view angle images of the object. The inspection device receives the plurality of the view angle images of the object so as to inspect surface of the object.

Systems and methods for sorting and imaging insects, including egg and larval life stages, useful for automated high throughput bioassays.

A rotation method includes bringing a conical first cone having a first rotation shaft into contact with a spherical body to be rotated at a first contact point of the spherical body from a first direction along the first rotation shaft and bringing a conical second cone having a second rotation shaft into contact at a second contact point different from the first contact point of the spherical body from the first direction and rotating the spherical body around an axis extending in a direction along a line segment which connects the first contact point and the second contact point to each other while the first cone and the second cone are relatively pressed against the spherical body from the first direction.

The invention relates to a candling apparatus for the rapid discrimination, removal and relocation of non-live avian eggs. The invention further relates to methods of use of the candling apparatus for the candling, removal and relocation of avian eggs.

An egg identification system for determining viability of an avian egg is provided. Such a system includes an emitter assembly configured to emit electromagnetic radiation toward an egg. A detector assembly is axially aligned with the emitter assembly to detect electromagnetic radiation transmitted through the egg. The detector assembly is spaced-apart from the egg during operation thereof such that the detector assembly does not contact the egg. The detected electromagnetic radiation is used to generate an output signal. The output signal is processed to determine whether there exists a periodic variation or an aperiodic perturbation in an intensity of the electromagnetic radiation transmitted through the egg corresponding to action of a heart or embryo movement, wherein the existence of the periodic variation or aperiodic perturbation indicates that the egg is viable. An associated method is also provided.

A ball is configured for use in racket and paddle sport games. These configurations include a material composition that is sensitive to mechanical force. This composition may change colors in response to a crack or other defect in the surface of the ball. In one implementation, the ball may have a thin, peripheral wall that encloses a hollow interior. This ball may find use in pickleball and, thus, meets the requirements and parameters for use in the sport.

An egg candling device according to the present invention includes at least an egg input and alignment unit for installing trays with eggs to be tested taken out from an incubator on a transporting means. An egg candling unit determines goodness or badness of eggs to be tested in the tray transported from the egg input and alignment unit, and specifies defective eggs. A disposal unit picks up the eggs determined as defective eggs in the egg candling unit. The egg candling unit includes light sources arranged above, a lift unit for lifting up the eggs to be tested installed below the tray and causing the eggs under test to contact the light source. A determining unit determines the goodness or badness of the eggs illuminated by the light source. A notification means specifies the position of the egg determined as a defective egg by the determining unit, and notifies the position to a disposal unit. The lift unit includes an egg holding base having a smaller diameter than diameters of eggs to be tested, a moving means for moving the egg holding base up and down, a tested egg holding unit has plate-like elastic members provided around the egg holding base at specific intervals and extending at a specific length above from the egg holding base.
