A method for visualizing an inclination of a motor vehicle in the motor vehicle, in which the inclination of the motor vehicle is measured and made visible in the interior of the motor vehicle. The inclination is made visible by interior lighting of the motor vehicle. At least one virtual plane is formed, which intersects the motor vehicle horizontally when the latter is in a horizontal position and serves as a reference plane for displaying the inclination. Changes in the inclination of the motor vehicle are modeled dynamically by the interior lighting by the sequential and/or parallel activation of illuminants of the interior lighting.

Example embodiments of the described technology provide apparatus and methods for measuring slope angles of surfaces. An example apparatus for measuring a slope angle of a surface may comprise a first laser and a second laser. The first and second lasers may be separated from one another and may be configured to emit parallel light beams towards the surface. The apparatus may also comprise at least one image sensor operable to capture images of the light beams scattered from the surface. The apparatus may also comprise at least one lens positioned to collect the light beams scattered from the surface and focus the scattered light beams onto the at least one image sensor. A controller may be configured to switch one of the first laser and the second laser off to avoid optical interference or cross-talk of the light beams emitted from both the first and second lasers at the at least one image sensor. Additionally, or alternatively, beams emitted by one or both of the lasers may be conditioned to avoid optical interference or cross-talk.

The present invention comprises a system for monitoring the angular movement of a structure's foundation, wall, beam and/or column with one or more monitoring devices in communication with either a local computing device (a hub) that displays the current angular deviation and direction from an initialized state, a remote server capable of generating a web page display of the current angular deviation and direction from an initialized state, or both. Additionally, the hub can be connected to the internet where data from the monitoring devices it is in communication with can be shared with a remote monitoring service, off-site server or both.

A measuring device for use with a laser level includes a measuring tape. A section of the measuring tape is substantially transparent and thus allows passage of a laser beam that is emitted by a laser level. Indicia of the measuring tape indicate a distance of the laser beam from a terminus of the measuring tape.

A tool, such as a level, including a rotating angle indicator is provided. The level may include a gripping structure for coupling the level to a workpiece. The level may include one or more bubble level vials. The level may include a window arrangement to provide viewing of an angle-indicating needle from a variety of angles, and one such window may be located at the end of the level and at least partially surrounds the angle-indicating needle.

In order to configure a housing (3) for a sensor received in the housing as deformation stable as possible the housing is made integrally in one piece from metal instead of being made from plastic and furthermore the pass through openings (6a, b) for attaching the sensor by bolting to another component are sized and positioned so that impartible forces are not able to deform the housing (3) which has a defined stability.

A level including a sensor that detects a tilt angle; a display unit including a plurality of strip-shaped display members that linearly emits light by an LED to display the tilt angle; and a controller that receives an output signal from the sensor and outputs a control signal so that a specific strip-shaped display member glows. The strip-shaped display members include one horizontal strip-shaped display member positioned at a middle of the display unit and a plurality of strip-shaped display members for tilt-angle display that has tips bent toward a center of the display unit. LEDs are attached to ends of the strip-shaped display members, respectively, and a pair of strip-shaped display members which is point-symmetrical with respect to the center of the display unit simultaneously glows according to the tilt angle.

An excavation measurement system includes a sensor to be mounted on excavation equipment to establish a light curtain in an excavation area, the light curtain to measure a parameter of the excavation area, and an interface to communicate the measure of the parameter of the excavation area.

An actuator to displace, for example a mirror, provides movement with at least two degrees of freedom by varying the currents in two electromagnets. A moving part includes a permanent magnet with a magnetic face constrained to move over a working area lying substantially in a first plane perpendicular to a direction of magnetization of the magnet. The electromagnets have pole faces lying substantially in a second plane closely parallel to the first plane, each pole face substantially filling a quadrant of the area traversed by the face of the moving magnet. An optical position sensor may direct a beam of radiation at the moving magnet through a central space between the electromagnets. The sizes of facets in a pupil mirror device may be made smaller in a peripheral region, but larger in a central region, thereby relaxing focusing requirements.

A system including a pointing rod 4 positioned on a measurement point X, a prism 3 fixed at a position deviated by a first fixed length L1 from the measurement point X in an axial direction PP of the pointing rod 4, an inclination casing 5 for fixing an analysis pattern 41 located at a position deviated by a second fixed length L2 from the prism 3 in an axial direction of the pointing rod 4 and is perpendicular to a surface with respect to the axial direction of the pointing rod 4, and a survey machine 2 having an image-taking section 22, a section of measuring a distance to the prism, and a section of measuring an angle 11,12. The position of the measurement point is measured from a position of the prism 3, an inclination direction A of the pointing rod 4, and the first fixed length L1.
