Abstract: According to various implementations, a computing device receives an image of a candidate mark and uses the image to create a profile of a feature of the mark. The computing device filters out, from the profile, all spatial frequency components except for a first band of spatial frequency components, resulting in a first filtered profile for the feature. The computing device repeats this filtering process for a second band of spatial frequency components, resulting in a second filtered profile for the feature, and may repeat this filtering process for further spatial frequency bands. The computing device compares the first filtered profile of the candidate mark with an equivalent first filtered profile of a genuine mark, and may repeat this process for further filtered profiles.

According to various implementations, a computing device (or logic circuitry thereof) receives (e.g., via a camera or via a communication network) an image of a candidate mark (e.g., a one-dimensional or two-dimensional barcode), uses the image to make measurements of a characteristic of a feature of the candidate mark, resulting in a profile for that feature. The computing device filters out, from the feature profile, all spatial frequency components that are indicated to be sibling frequency components. In some embodiments, the computing device carries out the reverse procedure, and filters out all spatial frequency components except for those indicated to be sibling frequency components.

Abstract: The invention relates to an elastic coupling device for connecting two drive shafts to a coupling disk, which is arranged axially between a first drive shaft and a second drive shaft and is arranged against the first drive shaft and the second drive shaft in a rotationally fixed manner. The coupling disk acts as a mechanical compensator during torque transmission between the two drive shafts. The coupling disk is retained without penetration by means of a plurality of circumferentially distributed clamping pieces, which are or can be connected to the first drive shaft and to the second drive shaft in circumferential alternation. The coupling disk and the clamping pieces are contoured in an axis-of-rotation direction in such a way that the clamping pieces encompass the coupling disk in a form-closed manner, wherein the form closure is effective in a rotational direction.

Abstract: A telescopable shaft assembly has at least two shaft elements capable of sliding in one another as an internal shaft element and an outer shaft element connected to one another in torque transmitting manner via at least one sliding splined portion. An axial fixation defines predetermined breaking point between the shaft elements. The axial fixation becomes ineffective once a predetermined impact force acting in a telescoping direction is reached. The shaft elements are movable relative to one another, once the axial fixation has become ineffective, in low-friction manner along the sliding splined portion under the action of the impact force. When the axial fixation is effective, an annular gap is formed between a splined portion runout on a free end of the outer shaft element and an unsplined portion of the inner shaft element. The annular gap, at least in the area of the free end of the outer shaft element, is at least partially filled with a sealant.

Abstract: Methods for maximum scene surface temperature estimation for blades with reflective surface properties in advanced stationary gas turbines are disclosed. The approach utilizes high speed infrared imagery provided by an online monitor system using a focal plan array (FPA) for near-infrared monitoring during engine runtime up to base load. The one waveband method for temperature estimation is assumed as starting point. A lower surface emissivity and higher surface reflectance of thermal barrier coating (TBC) in near-infrared can cause systematic estimation errors. Methods using the one wave band method, with the purpose to reduce estimation errors for maximum temperatures are also disclosed. Theoretical results, data from numerical simulations, and real data from engine test are provided. A system for performing temperature estimation methods is also disclosed.
