    Abstract: Securing data acquired by coordinate measurement devices including receiving a request from a requestor to access a data file including data that was acquired by a coordinate measurement device. The data file is retrieved and the content of the data file is authenticated. The authenticating includes retrieving an expected digital security attribute previously calculated by a digital security function based on content of the data file prior to the data file being retrieved. The authenticating also includes applying the digital security function to the data file to calculate an actual digital security attribute, and comparing the expected digital security attribute to the actual digital security attribute. Based on the comparing, a value of valid or not valid is assigned to an output of the authenticating.

    Abstract: Measuring with a system having retroreflector targets and a laser tracker includes storing a list of coordinates for three targets and at least one added point; capturing on a photosensitive array a portion of the light emitted by a light beam and reflected off the targets; obtaining spot positions on a photosensitive array of a tracker camera from the reflected light; determining a correspondence between three spot positions on the photosensitive array and the coordinates of the targets; directing a beam of light from the tracker to the targets based at least in part on the coordinates of the first target and the first spot position; measuring 3-D coordinates of the targets with the tracker; determining 3-D coordinates of the at least one added point based at least in part on the measured 3-D coordinates of the targets and the coordinates of the at least one added point.

    Abstract: A method for optically communicating, from a user to a laser tracker, a command to direct a light beam from the tracker to a retroreflector and lock onto the retroreflector includes projecting a first light to the retroreflector. Also, moving by the user the retroreflector in a predefined spatial pattern which corresponds to the command; reflecting a second light from the retroreflector, the second light being a portion of the first light; obtaining first sensed data by sensing a third light which is a portion of the second light and imaging the third light onto a photosensitive array on the tracker and converting the third light on the photosensitive array into digital form. Further, determining the first sensed data corresponds to the predefined spatial pattern; pointing the light beam from the tracker to the retroreflector; and locking onto the retroreflector with the tracker light beam.

    Abstract: A method for optically communicating, from a user to a laser tracker, a command to control tracker operation includes providing a rule of correspondence between commands and temporal patterns, and selecting by the user a first command. Also, projecting a first light from the tracker to the retroreflector, reflecting a second light from the retroreflector, the second light being a portion of the first light, obtaining first sensed data by sensing a third light which is a portion of the second light, creating by the user, between first and second times, a first temporal pattern which includes a decrease in the third optical power followed by an increase in the third optical power, the first temporal pattern corresponding to the first command, determining the first command based on processing the first sensed data per the rule of correspondence and executing the first command with the tracker.
