Abstract: The present invention relates to an aqueous ozone floor disinfection system. A floor cleaning machine traverses a floor surface entering a pre-hygienic zone prior to cleaning, cleaning within a midst-hygienic zone for a cleaning period, and moving away from the midst-hygienic zone creating a post-hygienic zone. An aqueous ozone generator receives water and generates an ozonated concentrate liquid. A post-hygienic mixer ratiometrically blends the ozonated concentrate liquid and water to form a post-hygienic ozone disinfection solution having a predetermined post-hygienic ozone treatment concentration. A post-hygienic nozzle spray of the post-hygienic ozone disinfection solution onto the post-hygienic zone portion of the floor surface for at least a post-hygienic treatment time absent agitation or removal by the floor cleaning machine improving disinfection of the floor surface. The service life of the aqueous ozone generator can be tracked and the disinfected floor surface can be GPS geofenced.

Abstract: A method and apparatus for reading a target object having areas of differing light reflectivity on the target such as a handheld bar code reader having a first illumination pattern, a detector for measuring a distance from the reader to a target object, a system threshold, and a comparator for evaluating the measured distance against the threshold. Should the reader's internal circuitry and/or software determine that the measured distance is greater than the threshold, a second illumination pattern is activated that has power effective illumination for increasing the operable reading distance between the reader and the target object. The second illumination pattern can be generated from a secondary illumination source or through a lens internal to the reader.

Abstract: An imaging scanner with a two dimensional array of sensors analyzes data from a segment of the array to detect if one or more indicia conditions is present that would prevent a successful decode based on data in the segment. In this manner, if decoding the indicia using data from the segment of array data is not possible, an enlarged frame of array data can be sought for decode when necessary while one-dimensional and simple two-dimensional barcodes can be quickly processed by loading and decoding only the segment of the array.

Abstract: An imaging-based bar code reader that includes an imaging and decoding system. When used on a stand to image documents, typically neither the stand or document is moving. Therefore blurring due to motion is not an issue. A sensor detects when the scanner is mounted to a stand. When commanded to take an image the scanner electronics and software modifies an auto-exposure process to minimize gain and lengthen exposure. This modification results in the scanner that is effective for scanning bar codes and yet also takes excellent pictures when mounted to a stand.
