Abstract: A window environmentally seals an imaging reader operative for reading a target by image capture. An integrated optical system having one or more optical elements is formed of one-piece construction with the window for optically modifying an aiming light and/or an illuminating light passing through the optical elements.

Abstract: A weighing scale is provided at a product processing workstation having a horizontal bed for supporting a horizontal bed window and an upright raised tower for supporting an upright tower window. A platter is mounted on the scale for joint movement therewith. The platter has a horizontal platter portion at least partly overlying the horizontal bed, and an upright platter portion at least partly overlying the raised tower. A guard on the upright platter portion overlies parts of the workstation for reducing weighing errors associated with weighing a product on the scale. The guard prevents the product from contacting and resting on the parts of the workstation and from being erroneously weighed.

Abstract: An imaging sensor of an imaging reader senses return light from a target to be read by image capture along an imaging axis over a field of view that extends along mutually orthogonal, horizontal and vertical axes. Two aiming light assemblies are offset from the sensor, and direct an aiming light pattern at the target. The pattern has an aiming mark in a central area of the pattern, and a pair of aiming light lines that are collinear along the horizontal axis. The visibility of the aiming mark is enhanced by optically configuring the aiming mark to be different in brightness and/or color and/or size and/or state of existence relative to a remaining area of the pattern. The aiming mark of enhanced visibility constitutes a prominent visual indicator of a center zone of the field of view.

Abstract: An imaging module for reading targets by image capture is mounted as a unitary assembly within an imaging reader. An imager is mounted on a first printed circuit board (PCB), and an interface connector is mounted on a second PCB. The first PCB is in direct, surface-area contact with first chassis walls of a chassis and is positioned to lie in a generally upright, first predetermined plane. The second PCB is in direct, surface-area contact with second chassis walls of the chassis and is positioned to lie in a generally tilted, second predetermined plane that is inclined at a tilt angle relative to the first predetermined plane. The first and second chassis walls are constituted as a one-piece support that maintains the tilt angle between the PCBs.

Abstract: An optical assembly for an electro-optical reader includes a lens mounted in a stepped barrel. The stepped barrel has a barrel step between first and second barrel portions. The optical assembly is installed along an optical axis in a stepped chassis having a first chassis section that receives the first barrel portion with a slip fit in which a mechanical clearance exists between the first chassis section and the first barrel portion, a second chassis section that receives the second barrel portion with an engagement fit in which the second barrel portion frictionally moves against the second chassis section, and a chassis step between the first and second chassis sections. The chassis step is spaced away from the barrel step after installation of the optical assembly to bound a debris compartment to trap any debris resulting from the frictional movement of the second barrel portion against the second chassis section.

Abstract: An imaging sensor of an imaging reader senses return light from a target to be read by image capture along an imaging axis over a field of view that extends along mutually orthogonal, horizontal and vertical axes. Two aiming light assemblies are offset from the sensor and are spaced apart along the horizontal axis at opposite sides of the sensor, and direct two aiming light marks, each having a predetermined brightness, at the target. The aiming marks are collinear along the horizontal axis and have inner end regions that overlap on the target to form a bright aiming mark having a brightness greater than the predetermined brightness to visually indicate a center zone of the field of view, as well as outer end regions that visually indicate approximate end limits of the field of view, over a range of working distances.

Abstract: A sensing unit mounted at a venue can capture images of targets in the venue, and/or can sonically locate targets in the venue, and/or can read targets configured as radio frequency (RF) identification (RFID) tags in the venue. A control arrangement recognizes whether at least one of the targets is indicative of an emergency in the venue, and automatically executes a remedial action in response to the recognized emergency.

Abstract: A light-transmissive window is positioned in direct, sealing contact with a chassis of an imaging module for reading a target by image capture. The chassis has a plurality of interior compartments, each having an opening. An imager, an aiming light source, and an illuminating light source are mounted on a common printed circuit board and individually contained in the compartments. The window covers each opening and environmentally seals, optically isolates, and resists entry of the light from the aiming and/or illuminating light sources into, the interior compartment.

Abstract: A battery pack for an electro-optical reader includes a rechargeable battery and a printed circuit board (PCB), both mounted in a battery housing. First and second electrical connectors are supported by the same PCB and/or the battery housing. The first electrical connector is connected to reader contacts in the reader when the battery pack is mounted in the reader. The second electrical connector is either connected to station contacts in a docking station when the reader is docked, or to a recharging cable.

Abstract: An illumination light source emits illumination light toward a target to be read by image capture. An imaging assembly captures the illumination light returning from the target along an imaging axis over a field of view that extends along mutually orthogonal, first and second directions that are generally perpendicular to the imaging axis. A compound parabolic reflector receives, and optically modifies, the emitted illumination light to generate a generally uniform illumination light pattern that is substantially congruent to, and substantially overlaps, the field of view along both of the first and second directions. The compound parabolic reflector has first and second pairs of parabolic segments for respectively reflecting the emitted illumination light over first and second illumination angles along the first and second directions.
