  • Publication number: 20220172406
    Abstract: A method and device for displaying desired positions in a live image of a construction site. The method mat include recording at least one position-referenced image of the construction site; linking at least one desired position to the position-referenced image; storing the position-referenced image together with desired position linkage in an electronic memory; recording a live image of the construction site, in particular in the form of a video, wherein the live image and the position-referenced image at least partially represent an identical detail of the construction site; retrieving the stored position-referenced image from the memory; fitting the position-referenced image with the live image, so that the desired position linked to the position-referenced image can be overlaid in a position-faithful manner on the live image; and position-faithful display of the desired position as a graphic marking in the live image.

  • Patent number: 11333497
    Abstract: A coordinate measuring and/or stake out device can be designed for being hand-held (one-handed), free carriage and movement by a user. A position giving means is for determination of an actual translational position of the device using an external position reference and an orientation giving means for determination of an actual rotational position of the device, such that the actual position of the device with respect to all six degrees of freedom of the device can be determined. A radiation source is for generation of a radiation beam as measuring and/or marking beam for measuring and/or visually marking of an object point. A beam steerer is for automatic steering of an alignment of the beam, whereby the beam which differ in the manner of automatic steering the beam alignment.

  • Publication number: 20080109587
    Abstract: A device (100) that includes a communications port (130), a first processor (135), at least a second processor (140), and a multiplexer (105). The multiplexer can selectively communicatively link the communications port to the first processor or the second processor. The multiplexer can include at least one switch (110, 115) and a switch controller (120) that controls operation of the switch. The switch controller can be responsive to at least one control signal (125) generated by the first processor. The first processor can generate the control signal in response to a command received from an external device (155) connected to the communications port. The command can be an attention command or a test software command. The switch controller also can be responsive to at least one control signal generated by the second processor.
