  • Patent number: 8265895
    Abstract: The present disclosure relates to interactive systems and methods for dimensioning with a mobile device. The mobile device can include an accelerometer, imager, and a corresponding algorithm configured to compute dimensions based on a plurality of inputs from the accelerometer, imager, etc. Specifically, the accelerometer allows the mobile device to measure acceleration and time, and the algorithm is configured to convert these measurements into distances. Additionally, with a three-axis accelerometer, the user can move the device off an axis being measured and still receive an accurate measurement, i.e. the algorithm can compensate for off-axis movement. Further, the present invention can incorporate an imager on the mobile device to provide additional compensation supplementing the algorithm and allowing the user additional freedom to be positioned away from the starting and end-point of a measurement.

  • Patent number: 8261991
    Abstract: A reader for and method of electro-optically reading symbols aim a front of a handheld housing at a symbol during reading. A solid-state, low resolution image sensor having a linear array of pixels is arranged in the housing and has less than 2000 pixels in number. The pixels sense return light returning along an optical path away from the symbol that is located in an extended range of working distances relative to the front of the housing. An imaging lens is positioned deep in the housing at an increased spacing of at least one inch as measured along the optical path away from the front of the housing, for capturing the return light over a reduced scan angle that is less than 40 degrees, and for projecting the captured light onto the sensor. A controller processes the return light sensed by the imager into data relating to the symbol.

    Abstract: An electro-optical reader for, and method of, reading a symbol, utilize a light source for emitting a light beam along a path, an optical assembly including a variable focusing element for focusing a major light fraction of the light beam between a range of working distances in which the symbol to be read is located along the path, and a controller for controlling the variable focusing element to have different focusing states. One of the focusing states is a reference focusing state in which the variable focusing element is operative for focusing the major light fraction at a reference focal plane. A detector assembly, including a detector aperture located at the reference focal plane, is operative for detecting an amount of a minor light fraction of the light beam, and for generating a self-calibration signal indicative of the reference focusing state when a predetermined amount of the minor light fraction has been detected.

  • Publication number: 20120199657
    Abstract: An imaging reader has a two-dimensional array of image sensors for capturing return light from a two-dimensional symbol over a field of view as pixel data to be stored in internal random access memory (RAM) of a controller even though the internal RAM has less storage bytes than the number of sensors. The controller determines a size and a location of the symbol in the field of view, maps and subdivides the symbol into a plurality of image capture zones based on the symbol size and location, sequentially captures the return light from each zone, sequentially stores the pixel data from each zone into the internal RAM, sequentially digitizes the stored pixel data from each zone as digitized data, and decodes the digitized data from all the zones.
