A 3D recording device () is provided including an image recording device (), a distance measuring device (), and an output unit (). An image processing device () is used to calculate, for a sequence () of images () recorded in different poses (), groups () of image elements () corresponding to each other and to determine for each group () a three-dimensional position indication () and to scale the three-dimensional position indication () with the aid of distance information () measured by the distance measuring device ().

3D recording device, method for producing a 3D image, and method for setting up a 3D recording device

This invention relates to a thermal imaging camera comprising a thermal imaging sensor and a cover plate that can be displaced between an open and a closed position by means of an electric drive. The invention is characterized in that the open and the closed position of the cover plate () form respectively self-locking end positions and that an electric drive is provided to switch between the end positions, said drive being supplied with no current in the self-locking end positions.

Thermal imaging camera comprising a cover plate

In a thermal imaging camera for acquisition of thermographic images of a measurement object, an electronic evaluation unit is integrated into the thermal imaging camera; it is designed for recognition of corresponding partial regions of the acquired thermographic images, and with it, the acquired images can be assembled into an overall image by overlapping the corresponding partial regions and displayed. The acquisition of the images preferably takes place during the swiveling of the thermal imaging camera over the solid angle region of the desired overall image.

Thermal imaging camera for taking thermographic images

In a temperature measuring device () an IR-radiation detector () and a reference element () are provided, connected to a surface () of an object () in a heat-conducting fashion, with a first area () with high emissivity and a second area () with high reflectivity formed at the reference element (), and the IR-radiation detector () is equipped for a separate detection of IR-radiation () from the first and second areas () and a surface area () of the object (). A computer () in the IR-radiation detector () is equipped to deduct a temperature measurement for the object (), corrected for emissions and reflections from the detected IR-radiations ().

Method for an IR-radiation&#x2014;based temperature measurement and IR-radiation&#x2014;based temperature measuring device

The present invention relates to a radiometer comprising an IR detector, a lens and a light source. The lens is arranged with respect to the IR detector such that it focuses IR radiation from a measuring surface to the detector. The light source emits visible light for marking the measuring surface. The beam path of the visible light extends through the lens. Moreover, the invention relates to a sighting device for a radiometer for visibly marking a measuring surface the temperature of which is measured by the radiometer. The sighting device comprises a light source for emitting a visible light beam, which marks the measuring surface. A piezoactuator controls the direction of the light beam. As an alternative to the piezoactuator, the light beam may be guided at a constant angular velocity, and a stepwise change of the direction of the light beam may be accomplished by a sectorized mirror. The invention finally relates to corresponding methods. In addition, the invention relates to the adjustment of light sources in a sighting device.

Radiometer, sighting device for a radiometer and method therefor

A portable electrical control and display device is described, having an indicator panel, a keyboard with at least one key pad, and a single housing designed as a single piece and made of a temperature-resistant material, which seals the control and display device in a water-tight manner.

Control and display device

The invention relates to a multilayer printing material () for a printing group () of a printer, comprising a support layer () and at least one printable layer (), self-adhesive on one face, that rests with its self-adhesive face () on a contact area of the support layer () in an adhesive manner. Said layer can be detached from the contact area and has at least one printable face (). At least one break point () is provided on the support layer () and is adapted to substantially compensate for any differences in length caused by the difference in length of the support layer () relative to the printable layer () when the printing material () passes through the printing group (). The invention further relates to the use of the inventive printing material.

Multilayer printing material and the use thereof

A protective device for holding an apparatus having an interaction field is formed from a dimensionally stable protective housing having a lower housing part and an upper housing part. The lower housing part and the upper housing part are releasably connected with one another and an inside contour of the protective housing is adapted and constructed to closely receive the apparatus. The protective housing may be watertight and is provided with a flexible operating area to enable an interaction field to be viewed and manipulated. The operating area may be integral with the rest of the protective housing. Seals are provided between the apparatus and the upper and/or lower housing part and possibly also between the upper and/or lower housing parts themselves. The seals may be formed of a sealing lip or O-ring mating with a circumferential groove. The protective device may also include sealed feedthroughs for connectors, such as cables and external sensors.

Watertight protective device for holding a measuring or display device

A waterproof protective device for holding an apparatus having an interaction field is formed from a dimensionally stable protective housing having a lower housing part and an upper housing part. The lower housing part and the upper housing part are releasably hingedly connected with one another and an inside contour of the protective housing is adapted and constructed to closely receive the apparatus with approximately zero play. The protective housing is provided with a transparent, elastically flexible operating area of reduced wall thickness to enable an interaction field to be viewed and manipulated. The operating area may be integral with the rest of the protective housing and may be sufficiently elastically deformable so that pushbuttons on the apparatus may be operated by finger pressure through the protective device under the operating area. A seal is provided between the upper housing part and the lower housing part, and is formed of a mating circumferential groove and rim, one or both of which may be provided with lips. The watertight protective device may also include additional features such as recesses on a side facing away from operating area to enable the protective device to be fastened to a matching mount or a stand fastened by a hinge to the protective housing. At least one reinforcing strip may be provided on the protective housing and formed from the same material as the protective housing. A watertight plug aperture may be formed in the protective housing. To facilitate removal of the apparatus from the protective housing, an area of reduced wall thickness and adjacent pusher may be formed on an area opposite a removal opening, so that an user can partially push the apparatus out of the lower housing part.
