The presently disclosed subject matter is generally directed to an alignment device that can be used in a wide variety of situations, such as (but not limited to) the installation of pipes, conduits, and drainage fittings. The disclosed device comprises a housing defined by a central channel. A laser passes through the housing central channel and is configured to emit a beam of light in a straight or angled line, visible to the user. The laser beam can be used to accurately position pipes, drainage fittings, and the like. In some embodiments, the device includes one or more adaptors of various sizes that can releasably attach to the housing. The adaptor functions an adaptor, selected to fit a desired pipe size to allow for proper positioning of the device. Thus, in use, the housing and/or a portion of the adaptor can fit into an open end of a pipe such that the laser beam emits a beam of light indicating a projected location for a connecting pipe or conduit. In this way, the installation of a pipe is more accurate and efficient.

A laser system (10) for generating a linear laser marking (34) on a projection surface (33), including a laser beam source (11), which generates a laser beam (25) and emits it along a propagation direction (26), a first beam shaping optical unit (12) embodied as a collimation optical unit and having a first optical axis (13), and a conical mirror (14) which is embodied as a right cone having a cone axis (15) and a reflective lateral surface (22) and is arranged in the beam path of the laser beam downstream of the collimation optical unit (12), wherein the cone axis (15) is oriented parallel to the first optical axis (13). The laser system (10) includes a second beam shaping optical unit (16), which is arranged in the beam path of the laser beam upstream of the conical mirror (14) and reshapes the laser beam into a ring beam (28) having an intensity minimum in the center of the beam.

A clamp for laser level detectors release mechanism is provided. The clamp includes a body, a shaft slidably coupled to the body, a fixed jaw, and a moveable jaw coupled to the shaft. The clamp permits adjusting the position and orientation of the laser level detector while the clamp remains coupled to a work piece.

An apparatus is for use with a rotary laser level system having a rotary laser level that shines a laser light that is received by remote re-positionable laser sensor, for mounting the re-positionable laser sensor in selectable elevation on a manually relocatable rod. The apparatus comprises a track presenting an outer face and rod-engaging face, and having a length extending between a top end and a bottom end, and a sensor carrier operatively mounted on the track for movement along the track. The sensor carrier comprises a housing, a wheel mounted on the housing in rotatable relation about a main axis, wherein the wheel is operatively engaged on the track such that rotation of the wheel causes movement of the wheel along the track, and means for selectively imparting rotation of the wheel about the main axis to thereby cause the sensor carrier to move along the track. In use, when the handle is rotated, the wheel correspondingly rotates, thereby moving the wheel along the track, and correspondingly moving the sensor carrier along the track to a selected position.

A laser level containing a housing, an electronic tilt sensor located in the housing; a controller to which the electronic tilt sensor is connected, and a laser module. The controller is communicable with a first display device and a second display device. The laser line is adapted to project a straight ground laser line on a flat surface. The electronic tilt sensor is adapted to detect a tilt of the laser level and provide a measurement signal to the controller. The controller is adapted to provide a display signal to the first and second display devices to display information about the tilt. By using an electronic tilt sensor, the laser level can provide accurate indicate of the tilt of the device and also allows such tilt information to be processed further.

A surveying instrument include a monopod installed on a reference point and a surveying instrument main body provided on the monopod, wherein the surveying instrument main body includes a measuring direction image pickup module which acquires first image including an object, a distance measuring unit which measures a distance to the object, a measuring direction detecting module which detects a measuring direction, a time detector which generates a reference time signal and an arithmetic control module, the arithmetic control module associates a distance measurement result with the reference time signal, associates a measuring direction with the reference time signal, and associates the first image with the reference time signal, associates an image change, the measuring direction, and a distance measurement result with each other based on the reference time signal, calculates a measuring direction in the distance measurement and determines a position of a measurement part of the object.

A levelling laser for generating a laser projection line on a surface is disclosed. The levelling laser includes an optical projection lens with a three-dimensional lens surface. The projection lens can be described in a three-dimensional coordinates system having three axes, X, Y and Z, arranged orthogonally to one another. The Z-axis coincides with the optical axis of the projection lens. The lens surface of the projection lens has a shape with a surface inclination angle rising monotonically along the X-axis. A corresponding projection lens is also disclosed.

A laser measuring system including first and second laser base stations and a laser receiver is provided. The laser receiver detects a first laser signal from the first laser base station. Location information associated with the first laser base station is extracted from the detected first laser signal. The laser receiver detects a second laser signal from the second laser base station. Location information associated with the second laser base station is extracted from the detected second laser signal. A position of the laser receiver is determined based on the extracted location information associated with the first laser base station and the extracted location information associated with the second laser base station.

A mount assembly including a rail, a mount configured to secure the rail to a surface, a laser assembly. The laser assembly includes a laser projector. The laser assembly is slidable along the rail.

A system and method for aligning projection of an optical indicia on a surface of a large object is disclosed. A reference is disposed in proximity to the object. The reference includes a plurality of markers spaced at intermittent locations. A projection system projects optical indicia onto the surface of the object. A detection system detects the markers disposed upon the reference and signals an image of the markers to a processor for the processor to register a location of the projection system relative to the reference. The reference is aligned with a feature disposed upon the object enabling registration of the markers to the object. A location of the projection system relative to the object is established enabling the projection system to project the optical indicia onto the object to a predetermined location.
