  • Patent number: 9976854
    Abstract: Embodiments provide for a geodetic instrument comprising a scanning head, a reflecting optical element, a radiation source, a control unit and an electronic distance measurement (EDM) unit. The scanning head is rotatable about a first axis. The reflecting optical element mounted in the scanning head and rotatable about the same first axis. The radiation source is adapted to emit light to be output along a light beam path from the geodetic instrument via light reflection against the reflecting optical element. The control unit is adapted to adjust an angular displacement profile of the reflecting optical element about the first axis relative to an angular displacement profile of the scanning head such that an angular displacement of the light beam path about the first axis as a function of time presents a stair-like profile. The EDM unit is adapted to determine a distance to a target during a flat portion of the stair-like profile.

  • Patent number: 8494561
    Abstract: One embodiment of the present invention relates to systems and methods for providing vehicles including construction machines and work vessels at a work site including construction work sites and naval work sites with real time position data from survey units located at the construction work site. In particular, a method according to the present invention includes the steps of accessing a network list identifying vehicles within the site; identifying, by using the network list, a vehicle requiring position data; and initiating a radio communication session with an identified vehicle during which the vehicle is provided with real time position data.

  • Patent number: 7913405
    Abstract: One embodiment of the present invention concerns a target for use with a measuring instrument in distance measuring and surveying applications. The target includes a base element, at least one light reflecting area arranged at the base element, the at least one light reflecting area being arranged to reflect light beams being incident in an angular area of substantially 360° degrees in plane, and an identification unit arranged at the base element and being adapted to emit signals having predetermined characteristics, wherein the predetermined characteristics may be used to identify the target.

  • Patent number: 7765084
    Abstract: In a position control arrangement for controlling the rotational position of a movable unit, especially for a surveying instrument, an electric motor is arranged to rotate the movable unit around an axis of rotation, and there are controllers for enabling the motor to stop the movable unit in a desired rotational position. The motor is a direct drive motor, the shaft of which forms the axis of rotation for the movable unit, and the motor is arranged to selectively operate in either a first, normal mode for rotating the movable unit to a desired position, or in a second, friction mode for providing resistance to a forced rotation of the movable unit from a predetermined position to a new position. A control unit detects the presence of a forced rotation and automatically changes the mode of operation in response thereto.

  • Patent number: 4392368
    Abstract: A press operating with hydraulic pressure comprises a pair of relatively movable components (8, 11) which during a pressing operation carry out a relative movement which is sensed. By use of the sensed relative movement a control signal is generated which is used for regulating the hydraulic pressure so that this is caused to vary with the relative movement according to a certain functional relationship. For generating the control signal a manually programmable electrical function generator (23) is provided, preferably a panel (29) comprising plug contacts (34), on which a plurality of pairwise associated pressure and movement values, constituting electrically and visually readable points in the desired functional relationship, can be set up.
