Various corporate, industry, and regulatory guidelines, best practices and standards are used in establishing acceptable levels of accuracy for volume dimensioning systems used in commerce. A volume dimensioning system can determine at least one distortion value that is indicative of an amount of distortion present in the system and responsive to the amount of distortion, autonomously alter or adjust the units of accuracy of information reported by the system. Such alteration or adjustment of units of accuracy may be performed based on an assessment of the distortion relative to a number of distortion thresholds. Responsive to the assessment, the volume dimensioning system can adjust a unit of accuracy in a representation of volume dimensioning related information.

Systems and methods of determining the volume and dimensions of a three-dimensional object using a dimensioning system are provided. The dimensioning system can include an image sensor, a non-transitory, machine-readable, storage, and a processor. The dimensioning system can select and fit a three-dimensional packaging wireframe model about each three-dimensional object located within a first point of view of the image sensor. Calibration is performed to calibrate between image sensors of the dimensioning system and those of the imaging system. Calibration may occur pre-run time, in a calibration mode or period. Calibration may occur during a routine. Calibration may be automatically triggered on detection of a coupling between the dimensioning and the imaging systems.

A system and method for measuring an item's dimensions using a time-of-flight dimensioning system is disclosed. The system and method mitigate multipath distortion and improve the accuracy of the measurements, especially in a mobile environment. To mitigate the multipath distortion, an imager captures an image of an item of interest. This image is processed to determine an illumination region corresponding item-of-interest's size, shape, and position. Using this information, an adjustable aperture's size, shape, and position are controlled so the light beam used in the time-of-flight analysis substantially illuminates the illumination region without first being reflected.

The present invention determines the dimensions and volume of an object by using a novel 3-D camera that measures the distance to every reflective point in its field of view with a single pulse of light. The distance is computed by the time of flight of the pulse to each camera pixel. The accuracy of the measurement is augmented by capture of the laser pulse shape in each camera pixel. The camera can be used on an assembly line to develop quality control data for manufactured objects or on a moving or stationary system that weighs as well as dimensions the objects. The device can also ascertain the minimum size of a box required to enclose an object.

A method, system, device and computer program product are provided for analyzing a cellular wireless communication network of a first type. For analyzing the cellular wireless communication network of the first type, communication connection condition parameters for one cell are measured, which communication connection condition parameters are derived from signals received by a mobile station from the one cell and from a plurality of other cells. The communication connection condition parameters are transmitted to a network control element in the form of mobile measurement reports. A network analysis functionality associated with the network control element processes the mobile measurement reports and evaluates, on the basis of processing results, a potential of the one cell for a usage in a wireless communication network of a second type, and/or estimated network parameters of the wireless communication network of the second type, like network performance or network dimensioning. This is repeated in all other cells in the wireless communication network of the first type.

The radar target attribute scattering center feature extraction method based on the sparse decomposition is capable of effectively extracting the target attribute scattering center and the super-resolution scattering center parameter, accurately estimating the geometric dimensioning features of the target and the important components of the target, and can be used for radar target classification and identification.

The invention relates to a table which has variable dimensions, especially a long length, and is mainly used in offices and conferences. The base of the table is supported by feet (6) and carries table leaves (1,1) which are brought together at the longitudinal sides thereof, and an insert (8,81) which can be inserted in-between said leaves, can have different configurations and can be used as a support for various structures. The base of said table comprises at least two transversal supports (2) provided with a central sunken channel region (20) from which two extension arms (21) respectively extended in opposite directions, the feet (6) being mounted on said arms, and lateral struts (4) supporting the table leaves (1,1) being arranged on the outside. The transversal supports (2) are interspaced in a parallel manner, perpendicularly in relation to the longitudinal direction of the table. An upwardly open sheet metal channel (3) having a preferably trapeziform cross-section is fixed in the longitudinal direction of the table on the two transversal supports (2). Containers (9′) for CPUs are suspended below the table in free positions on the lateral struts (4). The particular advantages of said table are essentially the stability, even for a long structure, and relatively low construction costs. The freedom in the dimensioning, the various inserts (8,81) and the differrent structures create a design which is adapted to individual requirements.

A method and apparatus for dimensioning and, optionally, weighing a cuboidal object. Four distance sensors are employed, one downwardly facing the top of the object, one facing one side thereof and two respectively facing mutually parallel sides of the object perpendicular to the one side.
