Various laser level designs including an improved core structure are shown. In one example, the laser level includes housing, a core structure, and a laser generator positioned within the cores structure and/or the housing. The core structure further inclu...

The device (10) has a telescope including a flat image sensor (5) e.g. CCD chip, arranged in an image plane (4) of a magnifying objective (3), and capturing an image of a laser beam (L) incident on the objective. A natural inclination compensator and an ev...

Provided is an electronic level capable of accurately measuring a height difference between two points even when a waving method of finding and determining as a measured height a minimum value of read heights while rocking a leveling rod back and forth is ...

The method involves determining a difference between an actual position (2) and a target position (3) using an evaluation unit (6). An acoustic indicator employs to indicate whether an actual position of a laser beam is above, below or at a target position...

The detector has a photodetector (6) having several photodiodes (8) which are offset along a line in a defined manner with respect to a reference point (7). A processor (11) has a parameter set (P) of an associated line laser transmitter (2) for emitting t...

The marking device has a receptacle unit into which a receiver can be inserted, e.g. by a clip, and a marking unit with a marking device for producing a marking on a reference surface. The marking unit has a marking device that can be positioned relative t...

The laser beam detector (1) has a photodetector (4), with a number of photo sensors (6) arranged at defined positions relative to a reference point (5), for detection of the pulsed laser beam (2). The photosensor signals are fed to an evaluation circuit (7...

A laser alignment tool includes a line laser assembly including a laser and emitting a laser beam line and an electronic target assembly including a photo detector array. The laser beam line of the laser is pointed toward the center of the photo detector a...

The invention is to provide a synthetic resin-made concave cone lens for radiating a standard laser line in a low cost in that accuracy of irradiation of a standard laser line can be assured, occurrence of defective products can be prevented, and advantage...

Photodiodes (1,2) detect a laser beam. An alternating current portion of the photodiodes is converted into voltages. Comparators (7) suppress background. Memory devices store signal positions generated by the laser beam. Luminous diodes (13,14) display the...
