An angle measuring device for optical angle measurement has a telescope body 5 which is rotatably mounted around at least one shaft (1, 2; 11), wherein the shaft (1, 2; 11) is rotatably mounted at least two bearing points 6, and the bearing points 6 are at a distance from one another in the direction of the shaft (1, 2; 11). In this case, at least two sensor arrangements for detecting the position of the shaft (1, 2; 11) are respectively arranged at a measurement point along the shaft (1, 2; 11), wherein the measurement points are at a distance from one another in the direction of the shaft (1, 2; 11). At least one of the sensor arrangements has a group of capacitive sensors (7a, 7b, 7c, 7d) which detect a displacement of the shaft (1, 2; 11) in directions perpendicular to the axial direction at the measurement point.
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
