Abstract: A device for optically checking objects in the form of preforms includes an inclined plate and the objects to be checked move from a top edge to a bottom edge of the inclined plate. The viewing angles of a plurality of image-recording units capture an entire width of the plate and synchronously record multiple respective digital images of the objects moving on the plate. Ejections fingers that can be individually pivoted by respective drives are arranged in parallel next to one another along the lower edge of the inclined plate. A processing unit is configured to identify all objects fully displayed in the images, check each identified object for at least one feature, track the object, and calculate at what time in and what rotational position each identified object reaches a position in the region of the ejection fingers. Depending on the calculation and the result of the test, the drive of at least one ejection finger is actuated to eject the identified object.

Abstract: A device and method tests preforms that are rotationally symmetrical with respect to an axis of rotation during their conveyance along a conveyance path. The device and method tests only a statistically relevant number of produced preforms, thus allowing substantial reduction in the constructive complexity required for aligning the preforms prior to being tested. A certain number of preforms that have not been correctly aligned are allowed to continue along the conveyance path without being tested.

Abstract: A separating device of an optical testing unit for testing rotationally symmetrical test objects includes two corresponding pocket wheels, each having a plurality of pockets distributed uniformly over a circumference. The pocket wheels rotate synchronously in opposite directions about parallel axes in response to a drive. A continuous conveyor transports the test objects on a transporting plane. Depending on the geometry of the test objects, the distances between the respective pocket wheels and between the pocket wheels and the transporting plane are determined so that the test objects, which are fed via and accumulating section, are moved between the pocket wheels while being guided by two pockets of the two pocket wheels and are released by the two pockets downstream of an engagement section. Once released the test objects are accelerated to a higher transporting speed in an accelerating section of the continuous conveyor and are separated as a result.

Abstract: Hollow bodies which are closed on one side and which are cylindrical are sorted by a sorting device. The hollow bodies have an end-side opening, a base surface situated opposite the opening and a shell surface extending between the base surface and the opening. The sorting device includes first nozzles arranged on an upper guide for conducting a first fluid flow in the direction of a lateral guide, and second nozzles arranged on a lower guide for conducting a second fluid flow in the direction of an outlet. Since the force of the fluid flow is several times greater if the fluid flow strikes a part of the shell surface of the hollow body through the end-side opening of the hollow body than if the fluid flow strikes the base surface of the hollow body from the outside, sorting of the hollow bodies is made possible.

Abstract: A method for the remote control of a function of a vehicle by a mobile operating device, involves enabling or disabling the function of the vehicle, such as an autonomous function for maneuvering into or out of a parking space, based on a sensed movement of the operating device. Enablement of the function requires that the sensed movement is a micromovement, a micromovement being a movement that is limited in the extent thereof and/or in the dynamics thereof.
