Abstract: A method of decoding a color barcode involves simultaneously illuminating the color barcode with three light zones in a manner that illuminates each bar of the color barcode with each of the three spatially separated light zones, where the three light zones are each illuminated by a different one of three colors; capturing a monochrome image of light reflected off of the color barcode that includes each of the bars in the barcode illuminated by the three light zones; and for each bar in the color barcode, determining a color of the bar by analysis of the intensity of the light captured in the image of the reflected light intensity in each of the three light zones.

Abstract: Various embodiments described herein illustrate a glove that includes an anterior portion and a posterior portion. The anterior portion is knitted seamlessly with the posterior portion to define a metacarpal region and a plurality of finger regions extending out from the metacarpal region. A first conductive pad is knitted on the anterior portion of the glove. The first conductive pad is knitted on a distal end portion of a first finger region. A second conductive pad knitted on the posterior portion of the glove. Further, the second conductive pad is knitted on a second finger region. An electronic device is removably attached to the posterior portion and is in electrical communication with the first conductive pad and the second conductive pad. The electronic device is triggered in an instance in which the first conductive pad contacts the second conductive pad.

Abstract: A method and system for synchronizing active illumination pulses in a multi-sensor imager is provided. The method has the steps of: providing an illumination pulse for each of N sensors from an illumination control block; setting each of N illumination pulses to have the same pulse period and active pulse width; setting the active width pulse for each of N illumination pulses to have maximum exposure time for each of N image sensors; ensuring during initialization of image capture that the time to capture a frame plus the time interval between subsequent image captures is the same for each sensor; monitoring the frame synchronous signal and corresponding illumination pulse for each sensor; obtaining the offset periods between subsequent frame synchronous signals from the monitoring step; adjusting the interval between frame captures; and aligning the negative edge of the frame synchronous signal and the corresponding illumination pulse.

Abstract: Systems and methods for cancelling noise caused by the flicker of ambient lights are provided. Such noise cancelling systems and methods may be incorporated in a laser-based barcode scanning device. In one example, a barcode scanning device includes a light source, a first sensor, a second sensor, and a noise cancelling circuit. The light source is configured to emit a beam of light. The first sensor is configured to detect a first optical signal indicative of light reflecting off of a barcode. The reflected light may originate from the light source and from at least one ambient light source in the vicinity of the barcode scanning device. The second sensor is configured to detect a second optical signal indicative of light originating from the at least one ambient light source. The noise cancelling circuit is configured to obtain a noise-cancelled scanning signal from the first and second optical signals.
