Abstract: A multi-function sound chamber for a handheld barcode reader may include the ability to (i) amplify or otherwise efficiently project an audible signal generated by a buzzer of the barcode reader to sound window(s), and (ii) provide stiffening support to a printed circuit board (PCB) on which an electromechanical switch is mounted that a trigger of the handheld barcode reader engages when activated by a user of the reader. The sound chamber may provide other functions, including isolating light between good/bad read signals and battery level status. Another function may include reducing electrostatic discharge (ESD) by providing a high-impedance seal around connecting screws. Another function may include retention of the PCB by providing a pocket with a compliant material to retain a top or other edge of the PCB. By having the sound chamber perform multiple functions, the barcode reader may be produced more efficiently and cost effectively.

Abstract: Systems and methods for establishing optimal reading conditions for a machine-readable symbol reader. A machine-readable symbol reader may selectively control reading conditions including lighting conditions (e.g., illumination pattern), focus, decoder library parameters (e.g., exposure time, gain), etc. Deep learning and optimization algorithms (e.g., greedy search algorithms) are used to autonomously learn an optimal set of reading parameters to be used for the reader in a particular application. A deep learning network (e.g., a convolutional neural network) may be used to locate machine-readable symbols in images captured by the reader, and greedy search algorithms may be used to determine a reading distance parameter and one or more illumination parameters during an autonomous learning phase of the reader.

Abstract: Systems and methods for preventing the unauthorized removal of mobile processor-based devices from designated areas (e.g., inside of a shopping area). The system may utilize a beacon technology based on a low energy protocol to prevent unauthorized removal of the devices. An anti-theft beacon system which includes an RF beacon transmitter may be positioned proximate an exit of a designated area. Mobile processor-based devices detect beacon signals from the anti-theft beacon system. Responsive to such detection, a device determines that it has been removed from the designated area. The device may then perform one or more anti-theft actions, including operating as a beacon once removed from the designated area. An auxiliary power source may power a beacon of the mobile processor-based device when the mobile processor-based device has been removed from the designated area so that the beacon may still broadcast signals even when a primary power source is disabled.

The system includes an image sensor that captures a plurality of images from the field of view of the image sensor. An occurrence of a gesture is detected in the plurality of images, in which the gesture is represented by a trace of a number of movements of a finger mounted indicia. In response to detecting the occurrence of the gesture, an at least attempt is triggered to decode one or more machine-readable symbols represented in the images. The gesture may be used to indicate a region of interest that includes the machine-readable symbol. Such indication may improve the efficiency and processing time needed to detect and decode a machine-readable symbol.

Abstract: A system and method for localizing an area of interest likely containing a digital watermark is disclosed. Image frames may be segmented into multiple tiles. A pixel having the maximum grayscale or other value and a pixel having the minimum grayscale or other value in each tile may be identified. Maximum and minimum image maps may be generated from the image frame by replacing each tile with the respective maximum and minimum grayscale or other value pixels. A background map may be generated based on a moving average of the grayscale values of the pixels in the image maps. Foreground map(s) may be generated based on the difference of the values from the image maps to the background map. A region of interest may be determined based on the background and foreground maps and provided to a watermark decoder. Content contained in the digital watermark may be read.

Through use of UWB signals, relative position (e.g., in front of or behind the beacon anchor) may be determined, thereby enabling different actions to be taken in response to determining the relative position.
