A leveling sensor, a load port including a leveling sensor, and a method of leveling a load port using a load port are disclosed. In an embodiment, a sensor includes an accelerometer configured to detect leveling and vibration of a load port and produce a plurality of data; a plurality of indicator lights configured to display a level measurement and a level direction based on the leveling of the load port; a processor configured to process the data produced by the accelerometer; and a wired connection configured to connect the processor to an external device.

An automatic leveling system includes a platform, a leveling device provided on the platform, a loading tray provided on the leveling device, three reflecting devices provided on the loading tray, an image acquisition device provided above the loading tray, a height positioning device provided on an end of the image acquisition device facing the loading tray, a light source configured to emit light, and a controller coupled to the image acquisition device. The height positioning device processes light emitted by the light source into three paths of light to the three reflecting devices. The three reflecting devices reflect the three paths of light. The image acquisition device acquires the three paths of reflected light into a light signal. The controller detects deflection values of the loading tray according to the light signal and controls the leveling device to level the loading tray.

The present disclosure discloses a device for determining orientation of an object. The device comprises a hollow spherical member. A plurality of sensors are positioned within a cavity defined by an inner surface and an outer surface of the hollow spherical member. Further, the device comprises a light source fixed within the hollow spherical member, and a solid sphere provided within the hollow spherical member. The solid spherical member is configured to displace within the hollow spherical member, pointing towards gravity and occupies lowermost position of the hollow spherical member, and thus blocks impingement of light on to corresponding one or more sensors at the lowermost position of the hollow spherical member. The blocked one or more sensors activate or deactivate, and generate a signal, which is received by a computing unit, to determine orientation of the object.

The present disclosure relates to a laser level system. The laser level system includes a mount, a laser secured to the mount and a remove input device. The mount includes a rotating portion to which the laser level is secured. The remote input device controls rotation of the rotating portion. The laser level is secured to the rotating portion of the mount such that when the rotating portion rotates, the laser level rotates concurrently along with the rotating portion of the mount.

A hydraulic hammer for a working machine configured for digging a surface includes a housing, a chisel, sensors, and a controller. The housing is coupled to the working machine. The chisel is partially enclosed by the housing and extendable from the housing for digging the surface at a contact location. Each of the sensors is configured for generating a signal indicative of a projecting distance between one of the sensors and the surface. The controller is configured for receiving the signals, determining an angle between the chisel and a plane substantially tangent to the contact location, and reorienting the chisel so that the chisel is substantially orthogonal to the contact location with the angle at substantially ninety degrees.

A system for determining alignment of a signal includes a light assembly comprising a light source operated by an electronic circuit, a first position sensor configured to measure a geographical direction of the light assembly, a second position sensor configured to measure a tilt angle of the light assembly, and a light communication device configured to receive measurements of the first position sensor and the second position sensor, and wherein the light communication device is configured to evaluate the measurements and determine alignment of the light assembly based on predefined tolerance thresholds for the geographical direction and tilt angle.

A vision laser receiver having a sensing surface with a fixed geometry such that laser light received by the sensing surface will illuminate a particular section of the sensing surface and the precise elevation and/or tilt of the laser receiver will be determined from the illumination of the sensing surface.

Technique for performing camera calibration on a vehicle is disclosed. A method of performing camera calibration includes emitting, by a laser emitter located on a vehicle and pointed towards a road, a first laser pulse group towards a first location on a road and a second laser pulse group towards a second location on the road, where each laser pulse group includes one or more laser spots. For each laser pulse group: a first set of distances are calculated from a location of a laser receiver to the one or more laser spots, and a second set of distances are determined from an image obtained from a camera, where the second set of distances are from a location of the camera to the one or more laser spots. The method also includes determining two camera calibration parameters of the camera by solving two equations.

A spirit level is provided that incorporates an illuminated optical indicator of the level orientation. The spirit level housing is at least partially translucent. At least one light-emitting diode (LED) is disposed within the housing for illuminating the translucent portions of the housing. Vertical, horizontal and angular orientation indication assemblies are provided including a tubular curved glass vial having a constant inner diameter at a viewing point and having a slight upward curve and incompletely filled with a liquid to create a bubble. An angle sensing circuit electrically connected to a battery controls the LED's to illuminate in a first color in a vertical orientation and in a second color in a horizontal orientation. Gradual changing of the color and/or the intensity of the light occurs during transition of the orientation between the vertical orientation and the horizontal orientation.

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.
