摘要： A portable dataform reader includes a large F# optic assembly that provides a working range from about 2.5" to at least 8.5" in front of the reader while maintaining a broad field of view. The reader is capable of capturing a high signal to noise ratio image in under 0.01 seconds thereby making the reader highly tolerant to hand jitter. To accommodate the large F# optic and short exposure period, the reader is provided with an efficient high intensity uniform illumination module.

摘要： A head mounted display system includes a frame that can be worn on a user's head wherein the frame supports a display and an optical system that projects an enlarged image of video information depicted on the display at a distance from the user. Also mounted on the frame so as to form an integral part of the head mounted display system is a barcode sensor for detecting one or more barcodes in the field of view thereof. A processor of the head mounted display system decodes barcodes detected by the sensor and determines the location of detected barcodes within the sensor's field of view. The processor utilizes the decoded barcode values and locations to control the video information depicted on the display for head tracking purposes or the like. The head mounted display system of the present invention has applications in both augmented field of view and virtual reality applications.

摘要： A hand held dataform reader for reading 1D and 2D bar codes and matrix dataforms is disclosed. The dataform reader includes a dataform reader module having a laser bar code dataform reading assembly, for reading 1D bar codes, and an imaging dataform reading assembly, for reading 2D bar codes and matrix codes. The dataform reader module further includes selection and control circuitry for energizing a selected one of the reading assemblies. In operation, the laser reading assembly is energized first. If the target dataform is a 1D bar code, a decodable signal will be generated and decoding circuitry will decode the target dataform. If a decodable signal is not generated by the laser reading assembly, the selection and control circuitry turns off the laser reading assembly and energizes the imaging dataform reading assembly. If the target dataform is a 2D bar code or matrix dataform, the imaging dataform reading assembly will generate a decodable composite video signal representing the image of the dataform. If the video signal is decodable, the decoding circuitry will decode the target dataform.

摘要： The invention features an image reader and a corresponding method for capturing a sharp distortion free image of a target, such as a one or two-dimensional bar code. In one embodiment, the image reader comprises a two-dimensional CMOS based image sensor array, a timing module, an illumination module, and a control module. The time during which the target is illuminated is referred to as the illumination period. The capture of the image by the image sensor array is driven by the timing module that, in one embodiment, is able to simultaneously expose substantially all of the pixels in the array. The time during which the pixels are collectively activated to photo-convert incident light into charge defines the exposure period for the sensor array. In one embodiment, at least a portion of the exposure period occurs during the illumination period.

摘要： Embodiments of the present invention comprise an indicia reading terminal including a focus element that extends the range of focus distances at which the indicia reading terminal can decode decodable indicia. In one embodiment, the focus element comprises a variable form element and a variable position element, the combination of which causes an image distance that can change in accordance with a separation distance between these two elements. The focus element can comprise an actuator, e.g., a piezoelectric actuator, which can be coupled to the variable position element in a manner that can cause the variable position element to deform the variable form element, and in one example, the deformation changes the focal length of the variable form element.
