  • Patent number: 10823565
    Abstract: A method for measuring a measurement distance between a rotating laser, which emits a first laser beam that can be rotated about a rotational axis and/or a stationary second laser beam, and a laser receiver, which has a detection field with a measurement function. The rotating laser is inclined in a direction of inclination by an inclination angle. The position of incidence of the inclined laser beam on the detection field of the laser receiver is determined as a measurement point. The distance between the measurement point and a zero position of the detection field is stored as the height, and the measurement distance between the rotating laser and the laser receiver is determined using the inclination angle and the height.

  • Patent number: 10823566
    Abstract: A method includes comparing a received beam hitting a laser receiver in a transverse arrangement with a rotating laser beam which is moved about an axis of rotation in a vertical position by a rotary laser. The laser receiver includes an evaluating unit and a detection field having a longitudinal direction and a transverse direction. The rotary laser is arranged on a rotational platform that can be adjusted about a rotation axis, and the vertical laser plane that the rotating laser beam produces is moved by the rotational platform in a direction of rotation about the rotation axis. In the longitudinal direction of the detection field, an adjustment direction of the received beam relative to the laser receiver is determined by the evaluating unit and the adjustment direction of the received beam is compared with the direction of rotation of the rotational platform by the evaluating unit.

  • Patent number: 10254392
    Abstract: A method to calculate position of a platform using a detection and ranging system coupled to the platform to transmit a signal to space object having a known ephemeris. The detection and ranging system receives the reflected signal from the space object. Taking the range of the platform from the space object using a time delay between transmission of the signal and receipt of the reflected signal and the range-rate using a Doppler frequency shift between the transmission of the signal and the receipt of the reflected signal makes it possible to calculate a position fix of the platform using the determined range, the determined range-rate, an altitude of the platform, and the known ephemeris of the space object.

    Abstract: A surveying appliance for surveying targets has a targeting unit and a remote control unit for prompting changes in the orientation of the targeting unit, equipped with measurement functionality for determining a three-dimensional orientation of the remote control unit or for determining movements by the remote control unit. The surveying appliance also has an evaluation and control unit. The extent or speed of the changes in the orientation of the targeting unit can be scaled to corresponding changes in an orientation or speed of change of orientation of the remote control unit such that at least two targeting modes having different levels of transmission ratio are provided. The surveying appliance can be used with corresponding handheld, moving remote control units, computer program products for providing, controlling and performing a targeting functionality for the surveying appliance and methods for tracking and surveying targets using the surveying appliance.

  • Publication number: 20140182146
    Abstract: A bow sight with at least one sight pin mounted to a frame assembly. At least one optical fiber is attached to the sight pin. The optical fiber is exposed to gather ambient light and to transmit light to a sight point located within the frame assembly. The eye alignment assembly includes an optical structure mounted to the frame assembly including a sight point of an optical fiber located near a proximal end of the optical structure and a lens with alignment indicia located at a distal end of the optical structure. An adjustment system permits the optical structure to be reoriented relative to the frame assembly. The eye alignment assembly provides an indication of orientation of the shooter relative to the bow in at least two degrees of freedom.

  • Publication number: 20140123508
    Abstract: A robotic laser-pointing apparatus has an instrument center, a first rotation axis, a second rotation axis, and a pointing axis, with the first rotation axis, the second rotation axis and the pointing axis in a known relationship to the instrument center. A laser source provides a pointing-laser beam along the pointing axis. A pointing drive system aims the laser beam by rotating the pointing axis about the instrument center in response to a pointing-direction control. Focusing optics having a focusing-optics drive serve to focus the pointing-laser beam in response to a focusing-optics control. A processor, responsive to target-position information, generates the pointing-direction control and the focusing-optics control. Some embodiments include an electronic-distance-measurement system having a measurement beam. Some embodiments provide for compensation of aiming errors of the pointing-laser beam and the measurement beam.

  • Publication number: 20140107883
    Abstract: A civil engineering machine has a machine control unit configured to determine data which defines the position and/or orientation of a reference point on the civil engineering machine in relation to a reference system independent of the position and orientation of the civil engineering machine. A geometrical shape to be produced on the ground is preset in either a machine control unit or a field rover control unit. The field rover is used to determine a position of at least one identifiable point of the preset geometrical shape in the independent reference system. Curve data defining a desired curve in the independent reference system, corresponding to the preset shape, is determined at least partially on the basis of the position of the at least one identifiable point of the preset geometrical shape in the independent reference system.

  • Publication number: 20140068956
    Abstract: A bow sight that decouples the shooter's bow cant from elevation adjustments. A segmented support assembly includes a proximal portion and a distal portion. The proximal portion is configured to attach to the bow. The distal portion is rotatably attached to the proximal portion and configured to rotate around a Y-axis relative to the proximal portion. A micro-adjust controls the rotational position around the Y-axis of the distal portion relative to the proximal portion. An elevation assembly is attached to the distal portion. A bezel assembly is attached to the elevation assembly. The elevation adjustment moves the bezel assembly along a substantially vertical axis while the bow is held at a bow cant greater than zero. The micro-adjust decouples the shooter's bow cant from operation of the elevation assembly. A windage assembly is optionally located between the elevation assembly and the distal portion.

  • Publication number: 20140068955
    Abstract: The invention encompasses archery bow sights that comprise at least one lens configured to eliminate parallax. In one aspect of the invention, the site includes at least one plus power ribbon accommodating lens supported by a support means. A reference means is forwardly mounted in front of the lens so as to be located along the archer's line of sight between the lens and a target when the archer is shooting the bow. The optical lens of the sight eliminates parallax so that the archer's eye does not need to realign his line of sight between an archery peep, the reference means, and the target when the archer changes elevation of the bow.

  • Patent number: 8605274
    Abstract: A method of operating a laser reference system orients a reference plane of laser light generated by a transmitter so compensation is made for rake angles between the first and second axes of the transmitter and first and second non-orthogonal alignment axes. The transmitter includes an optical system arranged to generate a laser beam, the optical system projecting said laser beam radially along a rotational arc defined about a central rotational axis, thereby substantially defining a reference plane of laser light, and a positioning arrangement, coupled to said optical system, for adjusting the angular orientation of the optical system with respect to a first transmitter axis and with respect to a second transmitter axis. Detectors are arranged to detect reception of the laser beam.
