| 141 | Mobile field controller for measurement and remote control | US14175825 | 2014-02-07 | US09377301B2 | 2016-06-28 | Gunnar Neier; Bernhard Metzler |
| A mobile field controller, together with a geodetic surveying device, forms a one-person measurement system for geodetic position determination. The field controller allows the spatial orientation of the field controller to be determined. The field controller supports a geodetic target object and has a distance-measuring unit that measures the distance between the field controller and a target point, the distance being optically marked by the field controller, as a result of which a 3D point cloud is generated without physical contact to a target point. When surveying a specific terrain region, algorithms analyzing the 3D point cloud are saved in a control and evaluation unit of the field controller. The absolute position of the target point is calculated from the data of the spatial orientation of the field controller, the distance between field controller and target point and the absolute position of the geodetic target object. | ||||||

| Various systems and methods for estimating the position of a radiation source in three-dimensional space, together with sensors for use in such systems are described. In some embodiments, the systems include a plurality of radiation sensors. The three-dimensional position of the radiation source is estimated relative to each sensor using an aperture that casts shadows on a radiation detector as a function of the incident angle of the incoming radiation. In some embodiments, the ratio of a reference radiation intensity to a measured radiation intensity is used to estimate direction of the radiation source relative to the sensor. When the angular position of the radiation source is estimated relative to two sensors, the position of the radiation source in three dimensions can be triangulated based on the known relative positions of the two sensors. | ||||||

| An angle-sensitive pixel (ASP) device that uses the Talbot effect to detect the local intensity and incident angle of light includes two local diffraction gratings stacked above a photodiode. When illuminated by a plane wave, the upper grating generates a self-image at a selected Talbot depth. The second grating, placed at this depth, blocks or passes light depending upon incident angle. Several such structures, tuned to different incident angles, are sufficient to extract local incident angle and intensity. Arrays of such structures are sufficient to localize light sources in three dimensions without any additional optics. | ||||||

| In a schlieren optical system, a laser beam is passed through the jet flow and the ambient around the jet flow, and a high speed sampling is performed using a high speed photo sensor while displacing measurement points. The value obtained by sampling represents a result of the optical path caused curved by a density gradient generated in an arc-shape from the center of the jet flow. The value is subjected to a high speed discrete Fourier transform and decomposed into frequency components which constitute the noise. Thereafter, Abel inversion is performed on data belonging to a particular frequency to obtain a density gradient in the radial direction from the center of the jet flow. The obtained density gradient is visualized in a graph display, so that the position of the sound source and the state of the jet flow can be accurately grasped. | ||||||

| A method and apparatus for resolving floating point and integer ambiguities in a satellite position navigation system is disclosed. A rover station is periodically positioned at unknown locations and has a satellite receiver capable of receiving the navigation signals. By calculating relative position coordinates between a base station in a known location and the rover station, and by calculating other position parameters relative to the satellite position, a geometric constraint based on a measured elevation angle between the rover and base station can be incorporated into data computations and processing to help resolve carrier phase ambiguities. The elevation angle is measured by transmitting multiple laser beams to an optical sensor on the rover station. This technique results in greater precision in determining the location of the rover. | ||||||
