Abstract: The invention relates to a laser system comprising a laser receiver collaborating with a laser emitter. The laser emitter is designed to provide a laser light plane and includes a control unit connected to a communication signal receiver in order to process and compute incoming communication signals from the laser receiver. The laser receiver comprising a communication signal transmitter for communicating with the laser emitter, a linear laser light photo sensor and an acceleration sensor both connected to a circuitry, which is designed to derive a movement of the laser receiver with respect to the detected laser beam of the laser emitter from computing and correlating the signals of the acceleration senor and the laser light photo sensor. The control unit includes an adjustment unit and adjustment is carried out by the adjustment unit in dependence of the processed and computed incoming communication signals of the laser receiver.

Abstract: A method, device and system for automatically deriving stationing zones for an electronic measuring or marking device in a worksite environment. The method includes querying a database (DB) for a construction plan information for the worksite environment and acquiring a worksite-task-information of a worksite-task to be executed. The worksite-task-information includes spatial points in the construction plan which have to be measured and/or marked to accomplish the worksite-task. It also comprises an acquiring of at least coarse 3D-data of the actual real world worksite environment, and a merging of the at least coarse 3D-data and the construction plan information to form an actual state model of the worksite environment. An automatic calculating of at least one stationing zone within the actual state model is established, the stationing zone including at least one stationing location from which the measuring or marking of the spatial points are accessible by the device without obstructions.

Abstract: A light receiver designed to determine a position or orientation relative to a reference light wherein the light receiver comprises an elongated rod-shaped light receptor with two ends, a light coupler, a light guide, and light detection means at one or both ends for detection of guided reference light and a signal processor to process the at least one detection signal of the detection means and to determine the position by an evaluation of the detection signal. The light coupler comprises light absorbing and emitting material like fluorescent or phosphorescent material.

Abstract: A light receiver designed to determine a position or orientation relative to a reference light wherein the light receiver comprises an elongated rod-shaped light receptor with two ends, a light coupler, a light guide, and light detection means at both ends and a signal processor to process the electric signals of the detection means and to determine the relative position and/or orientation by a comparative evaluation of the electric signals. The light guide serves as a light propagation path of defined length for light coupled into the light guide by the light coupler and the signal processor determines the position and/or orientation based on light propagation speed of the reference light propagating in the light guide.

Abstract: A construction laser system includes a rotating laser with self-leveling and a laser receiver. The system performs a self-leveling recalibration process by which-the self-leveling is checked automatically for quality and the related calibration data is updated automatically. A sequence of N calibration measurements is defined, where N is greater than or equal to three. The calibration measurements are obtained by the rotating laser and the laser receiver with a respective azimuthal alignment of the stand while the position of the laser receiver remains unchanged. As part of each calibration measurement, one output signal dependent on the laser beam impingement position is detected. The respective output signals or specified impingement positions are evaluated in pairs correlated with the respective I-th azimuthal alignments. The quality of the beam leveling functionality is thereby checked. If the requirements are not met, the previously stored calibration data can then be updated automatically.
