    Abstract: This provides an ID reader, typically configured for handheld operation, which integrates three types of illumination into a compact package that generates robust performance and resistance to harsh environmental conditions, such as dust and moisture. These illumination types include, direct (diffuse) light, low-angle light and polarized light. The ID reader includes a sealed reader module assembly having the illuminators in combination with an imager assembly (optics and image sensor) at its relative center. Additionally, also an on-axis aimer and a variable focus system with liquid lens have been integrated in this module and is placed on axis using a mirror assembly that includes a dichroic filter. As the optimal distance to read a code with low-angle light is typically shorter than the optimal distance to use the polarized illumination a variable (e.g. liquid) lens can adjust the focus of the reader to the optimal distance for the selected illumination.

    Abstract: This invention provides an aimer assembly for a vision system that is coaxial (on-axis) with the camera optical axis, thus providing an aligned aim point at a wide range of working distances. The aimer includes a projecting light element located aside the camera optical axis. The beam and received light from the imaged (illuminated) scene are selectively reflected or transmitted through a dichoric mirror assembly in a manner that permits the beam to be aligned with the optical axis and projected to the scene while only light from the scene is received by the sensor. The aimer beam and illuminator employ differing light wavelengths. In a further embodiment, an internal illuminator includes a plurality of light sources below the camera optical axis. Some of the light sources are covered by a prismatic structure for close distance, and other light sources are collimated, projecting over a longer distance.

    Abstract: A trigger arrangement for a scanning system can include a sealed housing configured to support a scanning device, a trigger, and an actuation device configured to control functionality of the scanning device. A first magnet can be positioned outside of the sealed housing and can be configured to be selectively moved by the trigger. A second magnet configured to be repelled by the first magnet can be positioned inside of the sealed housing. A connecting member that supports the second magnet can be configured to transfer force from the second magnet to the actuation device. Some configurations can provide tactile feedback to a user when the trigger is used.
