摘要： The method and apparatus of this invention facilitate operation of a bar code reader over a wider range of working angle and for a wider range of bar code densities. The invention includes improved optics and sensing elements. The optics and sensing elements and/or the associated circuitry are arranged to provide two channels of data derived form the scanned bar code. The two channels have differing resolutions. Analysis of the data from the two channels provides a single decoded result. As the working angle and density vary at least one of the resolutions will be appropriate for sensing all or most of the bar coded data. The data from the channel producing a valid result can be used, or if neither channel produces a valid result by itself, data from each channel can be analyzed and valid portions of the data from both channels combined to produce the single decoded result.

摘要： The invention facilitates operation of a bar code reader over a wider range of working angle, a wider range of distances from the bar code and a wider range of bar code densities. The invention includes improved optics and sensing elements. To provide a wider depth of field the optics associated with the emitter and or the photodetector have two distinct focal points. In the preferred embodiments, the optics and sensing elements and/or the associated circuitry are arranged to provide two channels of data derived form the scanned bar code. The two channels have differing resolutions. Analysis of the data from the two channels provides a single decoded result. As the working angle and density vary at least one of the resolutions will be appropriate for sensing all or most of the bar coded data. The data from the channel producing a valid result can be used, or if neither channel produces a valid result by itself, data from each channel can be analyzed and valid portions of the data from both channels combined to produce the single decoded result.

摘要： An imaging system with in-field image quality testing and reporting features, includes a housing, and a solid-state imager having an array of image sensors supported by the housing for capturing return light from a target located in a range of working distances from the housing in an image capture mode of operation, and for capturing return light from a test pattern positioned at a predetermined position in the range of working distances in a test mode of operation different from the image capture mode. An electrical signal indicative of the captured return light is generated in each mode. A memory is supported by the housing for storing a test program for testing image quality. A controller is supported by the housing for processing the electrical signal in the image capture mode, and for accessing the memory to enable the controller to execute the test program in the test mode to test the image quality of the test pattern imaged by the imaging system, and for reporting test results of the image quality of the test pattern.

摘要： Optical scanning of one- and two-dimensional barcode symbols is carried out first in an aim mode wherein the symbol is scanned using a first scan pattern that is relatively small and dense so as to be visible to the user and thereafter using a second, larger and more robust scan pattern for decoding. During aiming, the symbol is partially decoded to determine type and orientation, and this information is applied to control the angle of the scan pattern produced, the rate at which the scan pattern is increased for optimum decoding, and the ultimate pattern size. Preferred scan patterns, as well as unique scan mechanisms, are described.

摘要： A multi-bit digitizer for a bar code reader for detecting and reading bar code symbols, which are generally printed on a label or on the surface of an article. The multi-bit digitizer detects the presence of edges of a scanned bar code symbol, and also measures the strength of each detected edge therein. During a scanning operation, a sensor senses light reflected from a bar code symbol and produces an analog scan signal representative thereof. Positive and negative edges in the analog scan signal are detected, and timing signals are developed representative thereof. The strength of each detected edge in the analog scan signal is also measured, and digital signals are developed representative thereof. The timing signals and digital signals are directed as inputs to a decoder which performs multiple threshold processing on each individual analog scan signal by processing each analog scan signal a multiple number of times at different detection threshold levels. The ability to perform multiple thresholding on a single scan is significant for the development of very aggressive wands in which only a single scan is available for processing.

摘要： A method for estimating a location of a wireless device in a wireless local network is provided. The method includes forming a first set comprised of the signal strength received from access points that the wireless device received a signal from and an indicator of no signal strength measured for access points that the wireless device did not receive a signal from. Next, a scan subset can be formed comprised of access points in the first set that has associated signal strength. Next, a cluster comprised of the calibration points can be formed based on the scan subset. A distance between the first set and each of the calibration point in the cluster can be calculated. Then, the smallest distance can be selected as the location estimate.
