摘要:
A laser leveling tool comprises at least one laser diode for emitting a laser beam; a micro controller unit for controlling the operation of the laser diode; and a thermal sensor for sensing the internal temperature of the laser leveling tool; wherein the micro controller unit is configured to reduce the operation power of the laser diode when the sensed internal temperature reaches a temperature threshold.

A laser light reflective target that effectively brightens a laser light line being produced by a laser fan beam emitter. The target is placed on a jobsite floor and when two laser fan beams strike the reflective surface of the target, the laser beams appear much brighter than otherwise. The laser fan beams, when properly aimed at a point of interest, will intersect and produce an "X" shaped pattern of light on the target. The target can be used with a laser plumb beam pointer, which will aim its vertical beam downward directly at the specific point of interest if the target has been properly positioned. The laser plumb line pointer can additionally aim a second vertical beam upward, to produce a plumb line target point on the ceiling of an interior room that is being laid out.

Der Sensorträger (47) zur Durchführung zentrierter Aufstellungen über respektive unter einem definierten Punkt auf einer mit Stellschrauben (17a, 17b, 17c) versehenen, horizontal ausrichtbaren Plattform (1) eines geodätischen Instrumentenstativs weist ein Gehäuse mit gegebenenfalls zueinander parallel ausgerichteten, in eine Aufnahme der Plattform passende Deckflächen und ein mit den Deckflächen starr verbundenes optisches Mittel zum Sichtbarmachen eines Schnittpunktes der optischen Achse des optischen Mittels mit einer Referenzfläche auf. Die korrekte Einbaulage des optischen Mittels kann auch im Feldeinsatz leicht verifiziert werden. Zusätzlich kann der Sensorträger speziell angeordnete Röhrenlibellen (36a, 36b, 36c) aufweisen, die eine horizontale Ausrichtung erleichtern und eine einfache Verifizierung der korrekten Einbaulage der Röhrenlibellen (36a, 36b, 36c) ermöglichen.
摘要:
The present invention concerns a plumb-bob device for vertical pointing operation with a beam-casting housing (1) supported vertically by a plurality of legs (2) via a GIMBAL mechanism (3). The device has a reduced size, so that it can be handled quickly and conveniently on a construction cite. The legs (2) are mounted for expansion and contraction in and around an upper end portion (1a) via the GIMBAL mechanism (3) on and around an upper end portion (1a) of the housing (1). The legs (2) each have an inner surface (2c) complementary to the outer periphery (1c) of the housing (1). The device thus can assume a shape just like a long pencil when the legs are contracted. For vertical pointing operation, the housing (1) is held vertically by the legs (2) in an expanded state. The device can be used as an inverted plumb-bob device and also as a pointer by mounting a retaining member (5), which has a string, on lower end portions (2c) of the legs (2) in the contracted state thereof.

The present invention provides a laser leveling device, which comprises a light emitting unit for irradiating a laser beam, a rotating unit for rotating the laser beam for scanning, and a means for turning off the scanning laser beam so that a spotlike is formed in a specific direction. By forming a reference spot light , and aligning an irradiating point of the spot beam with the reference point, it is possible to install the laser leveling device 1 to the reference point and to perform accurate positioning of the laser leveling device by the scanning line of the laser beam formed on a portion other than the spot.
摘要:
A surveying instrument comprises a solid state image sensor (4) arranged to receive an image from a telescope, an emitter (6) for emitting a flash of light towards a target, and a controller for detecting and determining the position of the centre of the target on the solid state sensor (4) based upon the difference between an image received when the emitter (6) is on, and an image received when the emitter (6) is off. Means may be provided for adjusting the positions of the respective images, to allow for movement of the telescope in the time interval between the taking of the images.
