  • Publication number: 20190207400
    Abstract: A wireless electronic device is provided which comprises a rechargeable power supply and a power capacity indicator unit. The power capacity indicator unit comprises one or more sensors configured to detect that the wireless electronic device is out of a base charger and is in an idle state for a predetermined idle threshold. The one or more sensors are further configured to detect when a power level of the rechargeable power supply is within at least one predetermined power threshold range. The control unit is configured to activate at least one power status indicator corresponding to the at least one predetermined power threshold range when the wireless electronic device is detected to be out of the base charger and in the idle state for the predetermined idle threshold, and the detection of the power level of the rechargeable power supply is within at least one predetermined power threshold range.

  • Publication number: 20190172040
    Abstract: A point of sale system capable of operating in an indicia-reading mode or a verification mode is disclosed. In the indicia-reading mode, the point of sale system configures its illumination, imaging, and processing to read indicia as part of a normal checkout process. If triggered by a user or by an event, the point of sale system may operate in a verification mode. In the verification mode, the point of sale system enables the necessary illumination, imaging, and processing to verify an item. This verification includes illuminating the item in a way that causes a noticeable response from a security mark (or marks) on the item. An image of the response may be captured and processed to authenticate/verify the item. The point of sale system may then respond to the verification and/or may store the image/results as a record of the verification.

  • Patent number: 9685049
    Abstract: A barcode scanner should output one scanned result per scanned item at checkout. Scanners with large scan areas and multiple scan lines may scan an item more than once as it is dragged through the scan area during the checkout process. A timeout period, during which duplicate scans are ignored, may prevent duplicate scans from being transmitted. Scanners with integrated weight scales may require the use of the scan area for a weight measurement. As a result, weighed items may linger in the scan area longer than the regular timeout period and may be re-scanned. The invention embraces a method and system for mitigating this problem by using information from the scanned barcode and information from the scale to affect how duplicate barcode scans are handled for items requiring a weight measurement and not adversely affected with speed of input as may result with gating and virtual gating with disable/enable scanning commands.

  • Patent number: 9104930
    Abstract: An optical code symbol reading system includes a housing having a light transmission aperture, and at least one sound port formed in the housing. The system includes an optical code symbol reading subsystem for optically reading a code symbol in the field external to the light transmission aperture, and generating symbol character data representative of the read code symbol. An electro-acoustic transducer is disposed in the housing for producing sonic energy. Also, an acoustic-waveguide structure is disposed in the housing, for coupling the sonic energy produced from the electro-acoustic transducer, to the at least sound wave port formed the housing, to audibly signal the reading of a code symbol to the operator of the optical code symbol reading system.

  • Patent number: 8517271
    Abstract: An optical code symbol reading system including a hand-supportable housing having a light transmission aperture. A manually-actuated trigger switch is integrated within the housing. An optical code symbol reading subsystem is disposed in the housing for optically reading a code symbol in the field external to the light transmission aperture, and generating symbol character data representative of the read code symbol. One or more light emitting diodes (LEDs) are disposed in the housing, for producing a visible illumination. Also, an optical-waveguide structure is disposed in the housing for coupling visible illumination produced from the one or more LEDs, so as to illuminate the region about the manually-actuated trigger switch, thereby causing the optically-translucent region about the manually-actuated trigger switch to glow and visually indicate where it is located on the hand-supportable housing.
