    Abstract: An illustrative system may include a TDC configured to monitor for an occurrence of a photodetector output pulse during a measurement time window that is within and shorter in duration than a light pulse time period, the photodetector output pulse generated by a photodetector when the photodetector detects a photon from a light pulse having a light pulse time period; a PLL circuit for the TDC and having a PLL feedback period defined by a reference clock, the PLL circuit configured to: output a plurality of fine phase signals and output one or more signals representative of a plurality of feedback divider states during the PLL feedback period; and a precision timing circuit configured to adjust, based on one or more of the fine phase signals and/or the feedback divider states, a temporal position of the measurement time window within the light pulse time period.

    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.

    Abstract: A data decoding system can comprise a client computer including an imaging device and one or more servers executing at least one decoding process. The client computer can be configured to acquire an image of decodable indicia and to process the acquired image by: (i) identifying one or more areas of interest within the image; (ii) cropping the image based on the identified areas of interest; (iii) clipping one or more images from the image based on the identified areas of interest; (iv) increasing or reducing a pixel resolution of at least part of the image; (v) converting the image to a grayscale image or to a monochrome image; and/or (vi) compressing the image using a compression algorithm. The decoding process can be configured, responsive to receiving a decoding request comprising the processed image, to decode the decodable indicia and to transmit the decoding operation result to the client computer.

    Abstract: A system, method, and computer program for monitoring and corrupting a data stream, includes a data stream transmitting device having a barcode scanner that transmits a stream of data corresponding to a scanned barcode; a data stream receiver device having a barcode processing system that receives the stream; and a monitoring and corrupting device coupled therebetween having a database storing rules for detecting and corrupting patterns of data in the stream, and which monitors the stream, and based on the rules determines if the stream is unwanted, and if so corrupts the stream and transmits the corrupted stream to the barcode processing system so that the barcode data stream cannot be correctly received by the data stream receiver device. Otherwise, if the stream of data is wanted, the stream of data is allowed to be correctly received by the data stream receiver device.

    Abstract: An encoded information reading (EIR) terminal can comprise a microprocessor communicatively coupled to a system bus, a memory, a communication interface, and a pluggable imaging assembly identified by a type identifier and configured to acquire an image comprising decodable indicia. The imaging assembly can comprise a two-dimensional image sensor configured to output an analog signal representative of the light reflected by an object located within the field of view of the imaging assembly. The EIR terminal can be configured to output, by processing the analog signal, the raw image data derived from the analog signal and/or a decoded message corresponding to the decodable indicia. The imaging assembly can be communicatively coupled to the system bus via an imaging assembly interface comprising a plurality of wires and a multi-pin connector. The imaging assembly interface can comprise one or more wires configured to carry the imaging assembly type identifier. The EIR terminal can be configured, responsive to receiving the type identifier via the one or more wires, to retrieve from the memory one or more imaging assembly configuration information items corresponding to the type identifier and/or to receive via the communication interface one or more imaging assembly configuration information items corresponding to the type identifier. The EIR terminal can be further configured to control the imaging assembly using the imaging assembly configuration information items.
