In one aspect, a system for illuminating a field of view of a vision-based sensor mounted on an agricultural machine may include an agricultural machine having a vision-based sensor. The system may also include a light source configured to emit supplemental light to illuminate at least a portion of the field of view of the vision-based sensor. Furthermore, the system may include a controller communicatively the light source. The controller may configured to control an operation of the light source based on an input indicative of ambient light present within the field of view of the vision-based sensor.

A method for glare reduction may be implemented by a graphical code reader. The graphical code reader includes an optic system, a plurality of light sources, and a control system. The control system is configured to determine that glare is present in an image captured by the optic system by identifying reflection from at least one of the plurality of light sources. The control system may take a corrective action to reduce the glare in subsequent images. The control system may be configured to take a first corrective action if a diffraction pattern is present at a periphery of the glare, and take a second corrective action if a diffraction pattern is not present at the periphery of the glare.

A data storage device includes a controller and a memory. The controller includes a host interface and a memory interface. The controller performs a first operation on the memory through the memory interface at a first frequency associated with the host interface to determine a first data pattern. The controller performs a read operation on the memory through the memory interface at a second frequency to determine a second data pattern. The controller changes the first frequency by a predetermined amount until the first frequency is equal to a maximum operating frequency having an associated risk of a setup/hold violation that is below a predetermined probability.

A line-scan imaging camera can scan an object at a near field and a far field using a low F-stop value by reading out different rows on an imager. A line LED provides a line illumination over an object. Additionally, the imaging camera captures the illumination portion of the object through an optical path that includes mirrors that allow folded optics. The optical path is longer than the distance between the object and the camera. A mirror is located close to or adjacent to the line LED to provide efficient illumination and to align the initial leg of the optical path with the line illumination.

A digital imaging based symbol reading system has the capacity to automatically read both visible and invisible symbols in the same application environment. Typically, the system reads the symbols in a user-transparent manner. The system may employ visible/invisible illumination switching during operation. The system may include LED illumination sources. A method for reading both visible and invisible symbols using a single device is also disclosed.
