Abstract: An optical reader can include an image sensor. In one embodiment an optical reader can be configured to have different operating modes, the different operating modes optimizing the reader for reading different indicia. In another embodiment an optical reader can comprise a multiple color emitting light source. In another embodiment an optical reader can be provided in a specialized form factor including an enlarged head portion and an elongated body portion extending from the head portion.

Abstract: An indicia decoding device can have an image sensor and a laser diode assembly configured to project laser light onto a substrate. When a trigger signal is received by the indicia decoding device, the device can calculate a delay and enable the laser diode assembly if a delay threshold is satisfied. The indicia decoding device, in one embodiment, can include a hand held housing and an imaging module carrying the image sensor.

Abstract: The invention is an optical reader having a plurality of imaging modules. In one method for operating a multiple imaging module reader of the invention, a second frame of image data captured via actuation of a second imaging module is automatically captured and subjected to decoding in the case an attempt to decode using a frame of image data captured via actuation of a first imaging module fails. In another embodiment, a frame of image data captured via actuation of an image sensor of a first module and actuation of illumination of a second imaging module is subjected to decoding. In another embodiment, frames of image data captured via actuation of image sensors of spaced apart modules are combined. The various modules of a multiple imaging module reader can be adapted to have different best focus positions so that a field depth of the reader is improved.

Abstract: According to the invention, a multilayered image sensor is back mounted to a plate, and the plate in turn, is installed in a holding pocket of a device. In that the scheme takes advantage of a high controllability of a mounting plate's thickness, the mounting scheme provides a tight control of holding forces with which an image sensor is secured in an imaging device. In that the scheme provides for back mounting of image sensor on a planar surface, the mounting system provides tight control of an imaging assembly's pixel plane to fixed point in space distance.
