Abstract: An imaging module is supported by a housing of a reader for electro-optically reading indicia. The imaging module includes a solid-state imager having an array of image sensors for capturing return light from the indicia during reading. A laser scanning module is also supported by the housing and includes a scanner for scanning at least one of a laser beam from a laser and a field of view of a light detector in a scan pattern across the indicia during reading. A controller is operatively connected to the modules, and is operative for preventing reading interference between the modules during reading.

The dies can subsequently be transferred from the die plate having die cavities to one or more destination substrates or surfaces, by a punching mechanism.
Abstract: Methods, systems, and apparatuses for quadrature amplitude modulation (QAM) based radio frequency identification (RFID) systems are described. In an aspect, a tag transmitter performs QAM signal mapping and quadrature modulation of a carrier wave (CW), to transmit a QAM response signal. In another aspect, a QAM-enabled reader receiver receives the QAM tag response signal, and performs quasi-coherent signal processing, based on tracking of QAM signal parameters in a decision feedback loop.
Abstract: An illumination assembly for emitting light for imaging a target object having an illumination source that emits at least one light beam upon activation toward an illumination guide. The illumination guide has a first and a second side such that the light beam from the illumination source is scattered between the first and second sides. A textured surface is located substantially along the first side of the illumination guide. The scattered light exits the illumination guide from the textured surface to form a prescribed illumination pattern for imaging a target object.
Abstract: A plurality of solid-state imagers is mounted in a reader, such as a bi-optical, dual window, point-of-transaction workstation, for capturing images along different fields of view of diverse targets useful for customer identification, customer payment validation, operator surveillance, and coded indicia. The imagers are commonly mounted on a circuit board for joint installation at, and joint removal from, the reader for ease of serviceability.

Abstract: A thermal management system and method to control temperature in an RFID reader is described herein. In particular, by inserting variable periods of inactivity (or latency) at the beginning or at the end of each read cycle, proportional to an instantaneous temperature value of the RFID reader, over-heating and damage of RFID reader electronics is prevented. The RFID reader includes a thermal sensor and determines when the high power RF electronics is enabled. If the RFID reader is in an over-heated condition, it can be turned OFF and during this period any requests received on an interface to the RFID reader to perform a read of tag(s) are not processed.
