摘要： The transmitter has a generally flat, circuit board stator, a rotor including a plurality of magnets mounted in a ring around a central opening, and a bearing, supporting the rotor for rotation about an axis that extends through the central opening, A pentaprism assembly including an optics holder is mounted on the rotor for rotation therewith. The pentaprism assembly receives a beam of laser light through the central opening and redirects at least a portion of the laser light outward in a direction normal to the rotation axis. A laser source, mounted on the stator, provides a beam of laser light through the central opening to the pentaprism assembly. The beam of laser light is aligned with the rotation axis. The laser source includes a collimating lens positioned within the rotor. A shield plate of magnetic material beneath the stator exerts a force on the rotor in conjunction with the magnets, taking play out of the bearing. The transmitter uses Hall effect sensors on the stator to control switching current to coils on the stator. The transmitter also uses the outputs of the Hall effect sensors and a timer output to control dithering of the laser beam.

摘要： A two-dimension layout system identifies points and their coordinates, and transfers identified points on a solid surface to other surfaces in a vertical direction. Two leveling laser light transmitters are used with a remote unit to control certain functions. The laser transmitters rotate about the azimuth, and emit vertical (plumb) laser planes. After being set up using benchmark points, the projected lines of the laser planes will intersect on the floor of a jobsite at any point of interest in a virtual floor plan, under control of a user with the remote unit. An “active target” can be used to more automatically create benchmarks. A laser distance meter can be installed on base units to automatically scan a room or a wall to determine certain key features.

摘要： A modulated laser light detector that converts laser light energy into electrical signals which exhibit a frequency that is substantially the same as the laser light modulation frequency, in which these signals allow the detector unit to determine a position where the laser light is impacting upon a photodiode array. A superheterodyne receiver circuit is used to provide high gain at an improved signal-to-noise ratio to improve the range at which the modulated laser light signal can be reliably detected. Various types of signal detection circuits are available. Various processing algorithms are disclosed, including a Discrete Fourier Transform with a simplified computational algorithm for use with a low-power processor device.
