  • Patent number: 10222514
    Abstract: An autofocus lens system includes no conventional moving parts and has excellent speed and low power consumption. The system includes a small electronically-controlled focusing-module lens. The focusing-module lens includes two adjustable polymeric surfaces (e.g., two adjustable-surface lenses in a back-to-back configuration). The curvature of the surfaces can be adjusted to change focus. The performance of the autofocus lens system is extended by adding a conventional first and second lens, or lens group, on either side of the focusing-module lens. What results is an autofocus lens system with excellent near field and far field performance.

  • Patent number: 10013591
    Abstract: A system for reading code symbols includes an imaging subsystem that includes a focusing module and an image processor. The image processor selects an initial, predicted focal distance for the imaging subsystem's focusing module with respect to a code symbol. The focal distance for each successfully decoded code symbol is stored in memory, and a weighted average of a pre-selected number of memorized focal distances is used to calculate the next initial, predicted focal distance.

  • Patent number: 8740083
    Abstract: A focus adjustment apparatus (10) for a code reader (100) is provided which has an objective (12) having at least one lens and a drive (18) with a cam plate (16) for the positional adjustment of the objective (12). The objective (12) is supported in a parallel guide (14) having a coupling unit (32, 34) for the coupling of the cam plate (16) so that a rotational movement of the cam plate (16) adjusts the position of the objective (12) in the parallel guide (14) with a parallel shift of the objective plane. The coupling unit (32, 34) has a press-on element (32) for the play-free coupling of the parallel guide (14) to the cam plate (16) and a counter-bearing element (34) between the press-on element (32) and the drive (18) for relieving the drive (18) from the press-on element (34).

  • Patent number: 8720782
    Abstract: A barcode decoding system and method for compensating for motion of between an image sensor and a barcode to improve decoding of the barcode. The barcode decoding system includes an imager for capturing an image of the barcode, a motion sensor for collecting acceleration data and a processor that is configured to determine a velocity of the image sensor during the exposure period based on the acceleration data and a periodic motion model. The determined velocity is used to adjust the edge detection algorithm used to detect the barcode features in order to decode the barcode. The orientation of the captured barcode can also be determined in order to determine the velocity in a direction perpendicular to the barcode features.

  • Patent number: 8690062
    Abstract: Storing an event from a printed source in an electronic calendar can include a barcoded event ID on the printed source. A printed source can be any non-interactive visual display. The event ID can be in the form of a linear or matrix printed bar code and can include encoded information such as, but not limited to, event time and date, and event location. Optionally, the event ID can also include information such as an event contact name and contact information, as well as a possible event RSVP method and address. The event ID can be in lieu of human readable or commonly typed alphanumeric or special text information. In another embodiment, the event ID can be encrypted requiring an individual to have a decryption key to access the event information. An electronic calendaring application can generate and store an event in an electronic calendar from information encoded in the event ID barcode from a printed source.

  • Publication number: 20140070007
    Abstract: A barcode reading method and a barcode reading device are provided. An image sensor is utilized to capture an image of a barcode via an optical lens, and then a triangulation method and an ideal lens imagining method are collocated to calculate the digital image so as to produce an optimum image distance. A distance between the image sensor and the optical lens is then adjusted in accordance with the optimum image distance, so that the barcode can be immediately and clearly imaged on the image sensor.

  • Patent number: 8657194
    Abstract: A compact hybrid imaging lens assembly captures return light from a target over a field of view of a linear array of image sensors of a solid-state imager, and projects the captured return light onto the array during electro-optical reading of the target. The assembly includes a plastic lens for optical aberration correction, a glass lens spaced away from the plastic lens along an optical axis, and an aperture stop between the lenses and having an asymmetrical aperture through which the optical axis extends. The glass lens has substantially all the optical power of the imaging lens assembly for thermal stability, and the plastic lens has substantially no optical power. A holder holds the lenses and the aperture stop away from the array. Alignment elements on the plastic lens align the asymmetrical aperture relative to the linear array.

  • Patent number: 8646690
    Abstract: This invention provides a system and method for expanding the field of view of a vision system camera assembly such that the field of view is generally free of loss of normal resolution across the entire expanded field. A field of view expander includes outer mirrors that receive light from different portions of a scene. The outer mirrors direct light to tilted inner mirrors of a beam splitter that directs the light aligned with a camera axis to avoid image distortion. The inner mirrors each direct the light from each outer mirror into a strip on the sensor, and the system searches features. The adjacent fields of view include overlap regions sized and arranged to ensure a centralized feature appears fully in at least one strip. Alternatively, a moving mirror changes position between acquired image frames so that a full width of the scene is imaged in successive frames.
