Systems and methods for volume dimensioning packages are provided. A method of operating a volume dimensioning system may include the receipt of image data of an area at least a first three-dimensional object to be dimensioned from a first point of view as captured using at least one image sensor. The system can determine from the received image data a number of features in three dimensions of the first three-dimensional object. Based at least on part on the determined features of the first three-dimensional object, the system can fit a first three-dimensional packaging wireframe model about the first three-dimensional object. The system can display of an image of the first three-dimensional packaging wireframe model fitted about an image of the first three-dimensional object on a display device.

An apparatus for use in decoding a bar code symbol may include an image sensor integrated circuit having a plurality of pixels, timing and control circuitry for controlling an image sensor, gain circuitry for controlling gain, and analog to digital conversion circuitry for conversion of an analog signal to a digital signal. The apparatus may also include a PCB for mounting the image sensor integrated circuit and light source bank. The connection between the image sensor integrated circuit and/or light source bank and the PCB characterized by a plurality of wires connecting a plurality of bond pads and a plurality of contact pads, where the wires, bond pads, and contact pads provide electrical input/output and mechanical connections between the image sensor integrated circuit and the PCB. The apparatus may be operative for processing image signals generated by the image sensor integrated circuit for attempting to decode the bar code symbol.

Chip on board based highly integrated imager

A method is presented for correcting errors in a 3D scanner. Measurement errors in the 3D scanner are determined by scanning each of a plurality of calibration objects in each of a plurality of sectors in the 3D scanner's field of view. The calibration objects have a known height, a known width, and a known length. The measurements taken by the 3D scanner are compared to the known dimensions to derive a measurement error for each dimension in each sector. An estimated measurement error is calculated based on scans of each of the plurality of calibration objects. When scanning target objects in a given sector, the estimated measurement error for that sector is used to correct measurements obtained by the 3D scanner.

A system for reading code symbols includes an imaging subsystem that includes a focusing module and an image processor. The image processor selects an initial, predicted focal distance for the imaging subsystem's focusing module with respect to a code symbol. The focal distance for each successfully decoded code symbol is stored in memory, and a weighted average of a pre-selected number of memorized focal distances is used to calculate the next initial, predicted focal distance.

A system and method displays information using a vehicle-mount computer. The system includes (i) a computer touch screen for inputting and displaying information; (ii) a motion detector for detecting vehicle motion; (iii) a proximity sensor for detecting proximity to an item; and (vi) a vehicle-mount computer in communication with the computer touch screen, the motion detector, and proximity sensor, the vehicle-mount computer including a central processing unit and memory. The vehicle-mount computer's central processing unit is configured to store information associated with user-selected information from the computer touch screen and to display a zoomed view of the user-selected information on the computer touch screen. Further, the vehicle-mount computer's central processing unit is configured to override screen-blanking when user-selected information is displayed.

An autofocus lens system includes no conventional moving parts and has excellent speed and low power consumption. The system includes a small electronically-controlled focusing-module lens. The focusing-module lens includes two adjustable polymeric surfaces (e.g., two adjustable-surface lenses in a back-to-back configuration). The curvature of the surfaces can be adjusted to change focus. The performance of the autofocus lens system is extended by adding a conventional first and second lens, or lens group, on either side of the focusing-module lens. What results is an autofocus lens system with excellent near field and far field performance.
