| An electro-optical distance measuring device. Criteria are defined and stored which characterize a determined gesture for triggering the distance measurement, said gesture being carried out by a user using a test body that crosses the measuring light beam in an encoded manner. The analyzing and control unit is designed to carry out a measurement-triggering gesture mode in which reflected portions of the optical measuring light beam are continuously detected automatically and the continuously detected reflected portions are analyzed with respect to characteristic variables, the variables being dependent on a gesture that crosses the measuring light beam by means of a test body in an encoded manner. The characteristic variables are used to test whether the variables correspond to the defined criteria so that the gesture that is carried out by the user is identified as the gesture for triggering the distance measurement if the characteristic variables correspond to the criteria. | ||||||

| 87 | Volumetric error compensation system with laser tracker and active target | US12654911 | 2010-01-08 | US08803055B2 | 2014-08-12 | Kam C. Lau; Yuanqun Liu; Guixiu Qiao; Liangyun Xie |
| A volumetric error compensation measurement system and method are disclosed wherein a laser tracker tracks an active target as the reference point. The active target has an optical retroreflector mounted at the center of two motorized gimbals to provide full 360 degree azimuth rotation of the retroreflector. A position sensitive detector is placed behind an aperture provided at the apex of the retroreflector to detect the relative orientation between the tracker laser beam and the retroreflector by measuring a small portion of the laser beam transmitted through the aperture. The detector's output is used as the feedback for the servo motors to drive the gimbals to maintain the retroreflector facing the tracker laser beam at all times. The gimbals are designed and the position of the retroreflector controlled such that the laser tracker always tracks to a pre-defined single point in the active target, which does not move in space when the gimbals and/or the retroreflector makes pure rotations. Special mechanism and alignment algorithm are used in the gimbal design and retroreflector centering alignment to achieve accurate rotational axis alignment and repeatability. | ||||||

| To advance a dump truck quickly and smoothly to a position where target loading work will be performed relative to an excavating machine, the dump truck is placed in loading target position relative to the excavating machine. Geographic position is detected from GPS satellites of a GPS receiver of the dump truck. The position and direction of the geographic position is transmitted to the excavating machine as a target position image. The target position image and an approach route leading to the position are displayed on a dump truck display when the truck thereafter approaches the position. The dump truck thereafter approaches the position, and the truck is driven so that a current position image advances along the approach route to the target position image, whereby the dump truck is placed in the set loading image target position. | ||||||
| 91 | METHOD AND DEVICE FOR SIGNAL PERIOD STRETCH AND ULTRA-FAST SERIAL-TO-PARALLEL/PARALLEL-TO-SERIAL CONVERSION | US13515995 | 2011-11-02 | US20130211789A1 | 2013-08-15 | Shi Dong |
| Disclosed are a method and a device for signal period stretch and ultra-fast serial-to-parallel/parallel-to-serial conversion, which relate to the technical field of analysis and measurement control. The method is to change a propagation velocity of a target signal or displacement-reflecting the target signal, so as to extend or compress the period of the signal. Displacement-reflection is to generate a Doppler shift through interaction of the displacement of a reflecting plate with the target signal, so as to achieve period stretch; for a signal transmitted through a medium, the propagation velocity of the target signal is changed by changing the property of the medium, so as to achieve period stretch; for a signal ascribed to an electron flow, the movement velocity of the electron beam is changed through a varying acceleration field, so as to achieve period stretch. A target signal condensing/diffusing and collimating lens, a synchronous signal controller and a plurality of period stretch devices are utilized to achieve ultra-fast serial-to-parallel/parallel-to-serial signal conversion. Thereby, a device that originally cannot work at the frequency spectrum of the target signal is enabled to observe, transmit and parse content of the original target signal. | ||||||
