Abstract
An indicia-reading module is capable of integration into the smallest face of thin-profile smart device. The module employs chip-on-board packaging and a customized sensor enclosure to eliminate the stack-up height found in conventional packaging. The module also employs a customized frame to reduce volume by integrating circuit subassembly circuit boards into a unique architecture and by serving as the lenses for the illuminator and the aimer, thereby eliminating the need for any extra lenses or holders.
Claims20
An imaging module, comprising:
- an illuminator-aimer circuit subassembly, wherein the illuminator-aimer circuit subassembly is positioned on a circuit board;
- and
- a frame comprising at least two sides, the at least two sides defining a region, wherein the circuit board is positioned within the region and attached to the frame, wherein at least a portion of a first side of the frame is positioned in front of the illuminator-aimer circuit subassembly, wherein the frame serves as optics for the illuminator-aimer circuit subassembly.
An imaging apparatus, comprising:
- an imaging module comprising an illuminator-aimer circuit subassembly for projecting of an electromagnetic radiation and an aiming pattern within a field of view of the imaging module, wherein the illuminator-aimer circuit subassembly is positioned on a rigid-flex circuit board, the rigid-flex circuit board attached directly to a frame, the frame comprising at least two sides, the at least two sides defining a region within which the rigid-flex circuit board is positioned and at least a portion of a first side of the frame serving as optics for the illuminator-aimer circuit subassembly.
A method comprising:
- projecting an aiming pattern onto a target by an aimer driver circuit;
- aligning a reader module to the target according to the projected aiming pattern;
- projecting an illumination pattern by an illuminator driver circuit;
- capturing a frame of image data by an image sensor array,
- wherein the aimer driver circuit and the illuminator driver circuit are positioned on a rigid-flex circuit board, wherein the rigid-flex circuit board is positioned within a region defined by at least two sides of a frame, and wherein at least a portion of a first side of the frame serves as optics for the illuminator driver circuit and the aimer driver circuit;
- processing the frame of image data, wherein the frame of image data includes a windowed frame;
- and
- communicating the processed frame of image data to a host device by an interface circuit.
