Translation of "Optische hilfsmittel" in English

Optic helps: manual and mount in the same glass.

Wheelchairs, portable seats and optical aids are available on request from staff.

The orientation is preferably carried out without optical adjuvants, in particular by using mechanical aligning means.

The resultant joint is hermetically sealed and cannot be seen without optical aids.

Without visual aids visual checks are hardly possible!

An LED is widened by optical aids such as lens structures for instance.

We need optical aids, if we want to increase knowledge about Sun.

They can be spotted without optical help.

The aerodrome operator shall have procedures to ensure that aerodrome visual aids and electrical systems function as intended.

The aerodrome operator shall establish and ensure the implementation of a system of corrective and preventive maintenance of visual aids and electrical systems to ensure lighting and marking system availability, reliability and compliance.

Another advantage is that the time-proportional makings, recorded as additional information, are clearly visible only under microscopic inspection as is required in accident evaluations, and, therefore, do not appear as disturbances when the speed graph is viewed without the use of optical enlarging means.

The inventive method makes it possible to meet these requirements, thereby opening the way for exploiting the described optical effects to protect security threads against falsification, whereby these effects are testable easily and without optical aids and can only be imitated at high technological expense.

The described three-dimensional image viewing apparatus offers the possibility to perceive spatial objects which are reproduced through a pair of stereoscopic images as three-dimensional images, without the necessity to provide auxiliary optical means in the vicinity of the eye during viewing.

This must all be carried out in a micromedium, in which the human operator cannot work without optical aids.

Since the necessary enlargement is generally less than 10%, it is possible to do without further optical aids.

Since the magnification required is generally less than 10%, it is possible to do without further optical aids.

It is an object of the present invention to provide a workrest in which the coordinates for the positioning of the workpiece rails and the vacuum chucks are established by optical aids.

Such a reproduction device can already be derived from a large number of publications, since it is suitable for the production of images which are perceptible autostereoscopically, that is, three-dimensionally without additional optical auxiliary means.

To evaluate the processing properties, strips (dimensions: 435 mm×50 mm×2 mm) were produced on a so-called strip mould with a central sprue gate, and their surface was examined without an optical aid for the occurrence of delamination, in particular close to the sprue.

Sapphire can have any color and without optical instruments it´s not possible to divide red sapphires from rubys.

The 25 cm derived from the assumed distance from magnifying glasses and microscopes, in which one could see the object without optical aids still sharp.

Here, a macroscopically perceptible piece of image information is understood to be a piece of image information that is perceptible with the naked eye without optical aids.

Alternatively or in addition to this, further optical aids or displays can be provided in order to reduce, for example, perspective distortions and/or contortions.

The particular advantage in this case is that by means of such a “sidelooker” LED light can be emitted directly and without further optical aids parallel to the circuit substrate.
