    摘要: The position of a target lying on a plane is indicated by inputting a pointing direction which is computationally projected onto a plane. If the target is known to lie on a contour, the position is specified unambiguously. Alternatively, the position of a target can be specified by inputting its axial coordinates in successive steps. In another alternative approach, the image containing the target is translated and/or rotated and the target indicated again. The two direction projections are then used to determine the position of the target in 2-space. The direction indications may be input by a camera or other method, such as one or more radio transmitters.

    摘要: The present invention relates to a device containing an automatic zoom lens, and more particularly to a zoom lens that is controlled by a processor that is linked to a gaze tracking system. As a user looks onto an object through the device, the gaze tracking system collects data relating to the position of each eye of the user. This eye position data is input into the processor where the focal point of the user is determined. The processor then adjusts the zoom lens to zoom in or out onto the object based on either a predetermined or user input zoom factor.

    摘要: Targets associated with transactions to be processed at a workstation are read by capturing return light from the targets with an array of light sensors of a solid-state imager having a field of view that extends through a workstation window to the targets. A controller controls the imager to operate at a frame rate to acquire images of the targets over successive frames in either a batch mode or a free-running mode. A memory stores the acquired images. The controller processes all of the stored images, and processes at least one of the stored images over an extended time period greater than one of the frames.

    摘要: A method and apparatus for estimating an optimized exposure time for an imaging-based barcode scanner. The method includes (1) determining a SNR decodability function that enables a decodability value be determined from a signal-to-noise ratio; (2) determining a blur decodability function that enables a decodability value be determined from a blur value; (3) measuring a blur and a signal-to-noise ratio for an image captured with a first exposure time; and (4) determining an optimized exposure time based on the measured blur, the measured signal-to-noise ratio, and a combined decodability function that depends upon both the SNR decodability function and the blur decodability function.

    摘要: A device includes a memory, a wireless transceiver and a positioning system. The memory stores a first area in which a wireless network lacks coverage. The wireless transceiver is adapted to communicate with the wireless network. The positioning system determines a position of the device to determine whether the device is located within the first area. The wireless transceiver does not attempt to communicate with the wireless network if the positioning system determines that the device is located within the first area.

    摘要: An image capture system for, and a method of, reading an optical code during a reading mode, comprise an aiming assembly including a laser for emitting a laser beam having a variable intensity, and for generating an aiming pattern from the laser beam during an aiming mode prior to the reading mode, and an imager for detecting and capturing an image of the aiming pattern and the code over a field of view by exposure over an exposure time period during the aiming mode, and for detecting and capturing an image of the code over the field of view during the reading mode. A controller is operative for controlling the intensity of the laser beam during the aiming mode by increasing the intensity of the laser beam during the exposure time period to enhance detection and capture of the aiming pattern by the imager, and by decreasing the intensity of the laser beam frame outside the exposure time period for user safety.

    摘要: An acoustic based pointing device and a system and method for using the pointing device to move a cursor on a display screen of a display device. The pointing device comprises an acoustic source that generates and propagates an acoustic signal that is detected by four microphones M1, M2, M3, and M4 and is then converted into corresponding periodic electrical signals S1, S2, S3, and S4. The position vector P0 of the acoustic source is calculated by solving triangulation equations that depend on phase-shift time delays between S1 and Sj for j=1, 2, and 3. A position vector PC is calculated from P0 using a scale vector that relates a change in position of the cursor to a change in position of the acoustic source. Then the cursor is moved to a position PC associated with the position vector PC.
