Patent number: 11333497Abstract: 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.Type: GrantFiled: May 1, 2020Date of Patent: May 17, 2022Assignee: LEICA GEOSYSTEMS AGInventors: Stefan Eisenreich, Philipp Lukas Rüst, Matteo Carrera, Ismail Roman Celebi, Patrik Titus Töngi, Stefan Petkov, Josef Müller, Markus Geser, Hannes Maar

Publication number: 20080109587Abstract: 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.Type: ApplicationFiled: November 2, 2006Publication date: May 8, 2008Applicant: MOTOROLA, INC.Inventors: Philip Paul P.
