A system and method for identifying available cargo space and allocating that available cargo space while in transit includes a plurality of sensors for measuring space from reference surface of a cargo container to pallets in the cargo container. Such distances are aggregated to identify unused space in real time. The unused space is used by a freight management system to identify cargo along the same route that can use the unused space.

An optical measurement device includes: a light source, which emits light; a light reception portion, which detects a light reception amount of reflected light reflected on a target; a measurement portion, which measures a distance from the optical measurement device to the target based on the light reception amount of the reflected light; and a detection portion, which detects a portion of the target in which a light reception amount per unit time of the reflected light is smaller than a threshold value.

An apparatus and method for aligning two coaxially coupled rotatable shafts. A servo operated positioning device is movable along a longitudinal axis parallel to the axis of the shafts, and movable vertically to position a laser range (LRF) adjacent to the two shafts, which measures the distance between the LRF and a spot on the shafts. A controller having a processor and memory communicates with the positioning device and the LRF to collect data at two axial positions on each shaft. At each position the LRF measures the distance to the shaft and stores the measurement and location data. The LRF is vertically repositioned and the measurement and storing steps are repeated over a scan distance sufficient to provide enough data to determine the location of the shaft center. The processor then calculates and compares the shafts centerlines and determines the necessary adjustments needed to move the shafts into coaxial alignment.

The control target area is determined on a reference plane established with the two-dimensional camera as a reference.

A vision testing system is provided that tests the vision of an associated patient. A display of the vision testing unit includes a first surface for displaying a vision test thereon. A processing unit is operatively associated with the display and selectively displays optotypes on the first surface. A monitoring system senses a distance between the associated patient and the display, and operationally interfaces with the processing unit to provide data representative of the distance of the associated patient from the display. A cue may be provided to the associated patient in response to the sensed distance. In addition, ambient lighting conditions may be sensed at the display and brightness of the display altered in response to the ambient light.

A system and a method are disclosed including a dual laser measurement device (DLMD) coupled with a mobile computing device to measure dimensions of a building or other structure, calculate other quantities based on the measured dimensions, select building construction or finishing material, order the material, and save the list of the measured dimensions and ordered materials in a data storage device. All steps of this process from measurement to ordering material may be performed using a DLMD app running on the mobile computing device.
