Abstract: An illumination system is provided for an optical system that includes an imaging device for acquiring an image of a target, for decoding of a symbol or other analysis. The illumination system can include a first light source configured to provide illumination of a first wavelength, a second light source configured to provide illumination of a second wavelength that is different from the first wavelength. The light sources can be controlled for operations that include: illuminating the target with the first and second light sources simultaneously for acquisition of the image of the target; and altering an illumination output of at least one of the first light source or the second light source, while maintaining non-zero illumination output for at least one of the first light source or the second light source, to indicate a status of the optical system.

Abstract: This invention provides a vision system with an exchangeable illumination assembly that allows for increased versatility in the type and configuration of illumination supplied to the system without altering the underlying optics, sensor, vision processor, or the associated housing. The vision system housing includes a front plate that optionally includes a plurality of mounting bases for accepting different types of lenses, and a connector that allows removable interconnection with the illustrative illumination assembly. The illumination assembly includes a cover that is light transmissive. The cover encloses an illumination component that can include a plurality of lighting elements that surround an aperture through which received light rays from the imaged scene pass through to the lens. The arrangement of lighting elements is highly variable and the user can be supplied with an illumination assembly that best suits its needs without need to change the vision system processor, sensor or housing.

Abstract: The present disclosure provides a vision system camera, and associated methods of operation, having a multi-core processor, high-speed, high-resolution imager, FOVE, auto-focus lens and imager-connected pre-processor to pre-process image data provides the acquisition and processing speed, as well as the image resolution that are highly desirable in a wide range of applications. This arrangement effectively scans objects that require a wide field of view, vary in size and move relatively quickly with respect to the system field of view. This vision system provides a physical package with a wide variety of physical interconnections to support various options and control functions. The package effectively dissipates internally generated heat by arranging components to optimize heat transfer to the ambient environment and includes dissipating structure (e.g. fins) to facilitate such transfer.

Abstract: An electronic device includes an electronic circuit board containing a processing element and a vision sensor. A carrier frame is used to support the electronic circuit board. An optical element is positioned over the sensor and supported by the carrier frame. The electronic circuit board is bent to reduce the length, thickness and/or width of the electronic device, without increasing the others of the length, thickness and/or width of the electronic device.

Abstract: This invention provides a module for a handheld device. The module includes an imager with optics and image acquisition/processing processors that provide high speed acquisition and handling of acquired image data. The acquired image data is processed by the device processor using a module application that resides within the device. A removable retaining component mounts within the module's base portion. The retaining component varies to accommodate different devices. The base portion includes appropriate ports enabling optical transmission to, for example, cameras and illuminators so that various native functions of the device can be employed as desired. The base portion also houses a battery and charging assembly e.g. an inductive charging unit. The inductive charging unit can be adapted to pass data, in addition to power, between the inductive coils and the charging unit can be interconnected to a data network with attached devices that employ data from the module.
