| 20110078911 | ENCODER - An encoder for detecting measured values dependent on the rotation angle of the shaft of a motor includes a rotor, which can be fixed on the shaft, and a stator housing, which can be fixed by a bearing surface on an attachment surface of the motor and has a scanning means for detecting the relative rotational position of rotor and stator. In the mounted state, the rotor is fixed on the shaft and the housing is fixed on the attachment surface in such a way that the rotor and the scanning means have a defined axial distance (h). Additionally for mounting purposes, the encoder is pushed onto the shaft until the housing is held in a mounting auxiliary position with its bearing surface at an axial distance from the attachment surface, the axial distance corresponding to the defined distance (h). | 04-07-2011 |

| 20100245841 | Cylindrical grating rotation sensor - Disclosed is a Rotation sensor with a light source, a light detector, an internal part having a first lateral surface, which is globally cylindrical and convex, and an external part having a second lateral surface which is globally cylindrical and concave. The first and second lateral surfaces both have a same central axis defining a rotation axis for a relative rotation between the internal part and the external part the angle of which this rotation sensor can measure. A first grating is arranged at the first lateral surface with its grating lines parallel to the rotation axis, and a second grating is arranged at the second lateral surface with its grating lines parallel to said rotation axis. | 09-30-2010 |

| 20100023791 | Process for digital, bidirectional data transmission - The invention relates to a process for digital, bidirectional data transmission between a processing unit and a position encoder, as based on the transmission of frames of a predetermined bit length, such that each frame is provided with at least an initial bit length for the transmission of data from the processing unit to the position encoder and at least a second bit length for the transmission of data from the position encoder to the processing unit; and such that the frame is provided with a time slot in which data is neither transmitted from the processing unit to the position encoder nor from the position encoder to the processing unit. In the time slot a triggering signal (external sync signal) is transmitted from the processing unit to the position encoder and this triggers the acquisition of position data. In the first bit length, a clock signal for synchronizing the processing unit and the position encoder is transmitted from the processing unit to the position encoder, and after the acquisition of position data triggered by the external sync signal, the acquired position data is transmitted from the position encoder to the processing unit. Between the transmission of two successive external sync signals at least one additional position-data request signal (internal sync signal) is transmitted from the processing unit to the position encoder, and this signal triggers another acquisition of position data, which is followed by the transmission of the acquired position data from the position encoder to the processing unit. | 01-28-2010 |
