    Abstract: A dimensioning system includes: an emitter assembly to project a planar light beam into a scan volume; first and second image sensors to capture images of overlapping first and second portions of the scan volume; and a controller configured to: in response to an object travelling through the scan volume, for a successive pair of intervals defined by an operational frequency: at a first interval of the pair, (i) control the emitter assembly to project the planar beam and (ii) control the first image sensor to capture a first image of a top and a first side of the object; at a second interval of the pair, (i) control the emitter assembly to project the planar beam and (ii) control the second image sensor to capture a second image of the top and a second side of the object; and generate a three-dimensional image from the first and second images.

    Abstract: A label modification unit may receive a label modification input that indicates a label modification associated with content being written to a label or erased from the label. The label modification unit may identify an area of the label that is associated with the label modification according to the label modification input. The label modification unit may determine, based on a size of the area, a spot size of a light beam that is configured to be emitted by a laser printhead to modify the content within the area. The label modification unit may determine, based on the spot size and the content, an optical path configuration for the laser printhead. The label modification unit may operate the laser printhead according to the optical path configuration to write the content to the area or erase the content from the area.

    Abstract: Systems and methods for determining a position of at least one element are disclosed herein. The system receives, by a device having a first sensor, angle of arrival data from at least one element having a second sensor. The system receives position information of the device within a room and determines a difference in height between the device and the at least one element based on a first pressure measurement of the first sensor and a second pressure measurement of the second sensor. The system generates a vector between the device and the at least one element based on the angle of arrival data and determines a plane indicative of a height of the at least one element based on the determined difference in height. The system determines a position of the at least one element based on an intersection of the vector and the plane.

    Abstract: A laser printhead assembly for a laser printhead is disclosed herein. The laser printhead assembly may include a laser containment door; and a laser containment housing that is configured to form a sealed enclosure with a label support of a rewriteable label. The sealed enclosure may be configured to include the rewriteable label and the laser printhead. The laser containment door, in a laser-enabled position, may be configured to permit the laser printhead, via a light beam, to modify the rewriteable label and the laser containment door, in a laser-disabled position, may be configured to prevent a light beam from escaping the laser containment housing.

    Abstract: A label modification system is disclosed herein. The label modification system may determine a physical configuration of a rewriteable label. The label modification system may select a laser containment structure that is associated with the physical configuration. The laser containment structure may be one of a plurality of laser containment structures that are accessible to a placement device. The label modification system may cause the placement device to position the laser containment structure in association with the rewriteable label to form a sealed enclosure that includes a laser printhead. The label modification system may perform, based on a seal status associated with the laser containment structure and the rewriteable label, an action associated with the rewriteable label.

    Abstract: Methods and systems are provided for dimensioning a moving freight in motion along a path. An example system includes a plurality of laser line generators configured to emit coplanar laser beams forming a laser curtain oriented perpendicular to the floor and angled towards the direction of the path of the moving freight. A camera is configured to capture a series of two-dimensional images of the freight as it passes through the laser curtain. Additionally a positioning sensor is configured to detect the position and orientation of the moving freight as it passes through the laser curtain. A computing device in communication with the camera and the positioning sensor correlates each successive two-dimensional image with each corresponding position and orientation of the freight to obtain a composite three-dimensional shape of the freight. Furthermore, the computing device processes the composite three-dimensional shape of the freight to dimension the freight.
