Abstract: An angle measuring device for measuring an angular position of a stationary object with respect to an object which is rotatable around an axis of rotation, that includes a rotor which is connected to the rotatable object which rotates about the axis of rotation and a stator that includes a scanning unit for scanning a graduation, which moves in relation to the scanning unit. A coupler is fastened to the stationary object or stator so as to seat the stator on the stationary object that has a contact face which extends transversely with respect to the axis of rotation. The coupler has a contact face that extends transversely with respect to the axis of rotation and engages the clamping face of the stationary object or stator so that a clamping force is generated so as to fasten the coupler to the stationary object and wherein the coupler is fixed against relative rotation, but is radially and/or axially elastic.

Abstract: An interface technology is disclosed by which an application program running on a host can invoke a command to cause a third party copy engine (“3PCE”) to carry out a desired copy operation without actually generating the command needed by the 3PCE. A first code arrangement is provided, receipt of which causes a processor to generate a second code arrangement representing a third party copy command and its corresponding parameters. Also, a liaison system and method are provided. The liaison system is interposed between an application program running on a host and a 3PCE external to the host. Such a liaison system comprises: an application program interface (“API”) to receive the first code arrangement (mentioned above); and a copy command generator to generate the second code arrangement representing the third party copy command and its corresponding parameters.
