Abstract: Example media scanning assemblies are disclosed. In an example, the media scanning assembly includes a media feeder assembly including an output tray, an input tray disposed vertically lower than the output tray, and a first scanning device. In addition, the media scanning assembly includes a flatbed scanning assembly coupled to the media scanning assembly. The flatbed scanning assembly includes a transparent platen and a second scanning device to move relative to the platen. The media feeder assembly includes a media path extending from the input tray, across a portion of the platen, to the output tray, and the media feeder assembly is to advance media along the media path from the input tray to the output tray so that the first scanning device is to scan a first side of the media and the second scanning device is to scan a second side of the media through the platen.

Abstract: An example scanner device includes a sealed enclosure including a scan window to allow light to enter the sealed enclosure, and an optical assembly including a light source and an image sensor. The light source is to emit light through the scan window onto a medium to be scanned. The image sensor is to capture light reflected by the medium through the scan window. The optical assembly is rotatably positioned within the sealed enclosure. An actuator is disposed within the sealed enclosure to rotate the optical assembly to aim the optical assembly at different locations on the scan window.

Abstract: Embodiments of the invention are generally directed to a system and method for enrolling a user into an authentication system. In some embodiments of the invention, a user completes a first portion of the enrollment or setup process using a first computer environment, but is not permitted to complete the enrollment or setup process from the first computer environment. The system permits the user to complete the enrollment or setup process only from a second computer environment different from the first computer environment. In one embodiment, the second computer environment is any computer environment outside of the first computer environment.

Abstract: Systems and methods are disclosed for detecting media edges in an automatic document feeder including a scan backing strip that is colored to contrast with the color of a medium being fed through the automatic feeder. Logic instructions are included that cause a computer processor to detect when the medium is being fed through the automatic document feeder based on the difference in color between the scan backing strip and the medium.

Abstract: An adaptive digital ramp current control system comprises a digital current ramp controller configured to digitally ramp a current level supplied to at least one light emitting diode (LED) according to a predetermined ramp profile, the ramp profile comprising at least one intermediate current level step between a minimum current level and a maximum current level.

Abstract: In one embodiment, a scanning device includes a light source configured to selectively illuminate an area of interest and a light sensitive receiver configured to receive light from the light source and generate signals based on the received light. Control logic is configured to power the light source at a power level, generating mid-tone-scan signals at the light sensitive receiver. Calibration logic is configured to determine a calibration factor for a selected pixel based data including the mid-tone-scan signals.

Abstract: A circuit connected to a linear array of photosensors generates image data representative of information printed on a document and adjusts the gains applied to the outputs of selected ones of the photosensors to eliminate streaks in the image data otherwise due to the selected photosensors imaging debris on an optical reference surface. The circuit determines which photosensors have low output values during a factory scan of a clean white reference surface. During a subsequent user environment calibration scan, low output values are adjusted to the average of their neighbors, but only for locations not identified as having low outputs during the factory scan. The circuit additionally performs a PRNU compensation and further adjusts the gains applied to each of the outputs of the photosensors so that all of their output values have a substantially uniform value.
