Abstract: A head band for diagnostic instruments comprising a light source and a battery has, at its back support part (12), a flat housing (21) for adjusting and fixing the head band length by means of a rotary knob (22). An accumulator module (31) optimized with regard to volume, weight and weight distribution can be mounted and detached by means of bayonet-type grooves (25) at the housing (21) and pins (33) at the accumulator module (31), and can be fixed by means of a resilient spring (26) at the housing (21) and a recess (34) in the accumulator module (31) without impairing the function of the rotary knob (22).

Abstract: A battery grip for diagnostic units comprises a grip sleeve for accommodating batteries, at the upper end of which a metal sleeve for accommodating a consumer load, such as an electric bulb, is mounted, a guide opening formed in the wall of the grip sleeve, a switching slide being guided the guide opening in a longitudinal direction of the grip sleeve, a contact member extending from a lower end of the grip sleeve with one contact end into the guide opening, and a contact spring member having one end conductively connected to the metal sleeve manner and another free end extending into the guide opening such that the free end is disposed above the contact member and is brought into contact with the contact member by displacing the switching slide. The contact between free end of the contact spring member and the contact member is created by at least two contact points. At least one longitudinal recess is provided in the contact end of the contact member.

Abstract: A tire testing facility is used for testing tires. To improve such tire testing facility, the same comprises a tire testing device with one or more testing heads (5) for testing the inner running surface (8) of the tire (1) and one or more testing heads (6, 7) for testing the outer sidewall (3, 2) of the tire (1).

Abstract: The invention serves for the contour measurement and/or deformation measurement of an object, particularly a tire or a structural component of a composite material. The object is irradiated with light, particularly structured light, that is emitted by a radiation source and consists, in particular, of coherent light or partially coherent light, especially laser light. The light reflected by the object is picked up by a camera with an imaging sensor. In order to improve the image quality, a first image is produced with a first adjustment of the camera and/or the radiation source which is adapted to a first image region (13). In addition, a second image is produced with a second adjustment of the camera and/or the radiation source which is adapted to a second image region (12). Both images are combined (FIG. 5).

Abstract: A headband apparatus for head-worn optical instruments includes a headband (12) and a bow (16) on which the optical instrument is fitted, and which is fitted with both its ends (100) to the middle region of the headband (12) such that it can swivel about a swivel axis (S) between a working position and a rest position. Fastening elements (26, 28) for releasably fastening additional elements (38) are fitted on the headband (12).

Abstract: A method serves to determine the 3D coordinates of an object. The 3D coordinates of a partial surface (6) of the object are determined by a 3D measuring device (3), which includes one or more detectors (4) and whose position is determined by a tracking system. The 3D coordinates of an adjacent partial surface (7) of the object are determined by the 3D measuring device (3). The 3D coordinates of an overlap region of he adjacent partial surfaces (6,7) are put together by a matching method. In doing so, an error function is determined and minimized iteratively. Furthermore, the error function of a detector (4) of the 3D measuring device (3) is determined.

Abstract: The invention relates to a method for determining the 3D profile of an object. In order to improve a method of this type, several sections of the object (5) are measured. During at least one measuring operation, at least one reference object (4) is measured. The measured sections of the object (5) are combined (1).

Abstract: An ophthalmoscope includes a housing (12) in which there are arranged an observing unit and a light source between which there are/is arranged a diaphragm and/or a filter device that can be set via a swivel lever device (16, 17) mounted outside on the housing (12). The swivel lever device (16, 17) can be locked in respective latch stages by a locking device (41).

Abstract: A procedure serves for the testing of tires by means of a testing system. The testing system includes a memory in which geometric data (1, 2, 3, 4, 5, 6) of the tire (7) are stored, and at least one probe (8) for testing the tire (7) surface. To improve on such a device, the probe or probes (8) are positioned with due consideration for the geometric data (1-6) of the tire (7) for the testing of the tire (7) surface (FIG. 1).

Abstract: An apparatus for the inspection of the surface (1) of a tire (2) or the like comprises a projector (3) for the projection of a pattern onto the tire (2) and a camera (4) for the taking of an image of the pattern projected onto the tire. A simplified apparatus of this type comprises an apparatus for the rotation of the tire (2) about its axis (5).
