Abstract: A method and apparatus for providing current pulses to the illumination source in an imaging scanner. The method includes: (1) sensing a current supplied from a current port to obtain a current-monitoring signal; (2) controlling a charge current provided to a storage capacitor based on the current-monitoring signal; (3) measuring a parameter related to a voltage across the storage capacitor; and (4) generating a driving current for the illumination source by the illumination driver circuit, if the parameter is above a predetermined threshold value, to provide a driving current for a illumination source in an imaging scanner.

Abstract: A method and device enables improving a signal to noise ratio (SNR) of a backscatter signal received from a radio frequency identification (RFID) tag. The method includes generating a continuous wave (CW) carrier signal at the reader device (step 505). An amplitude modulation (AM) noise component of the CW carrier signal is then detected (step 510). The AM noise component is inverted to an inverted noise signal (step 515), and the inverted noise signal is summed with the CW carrier signal to provide an AM noise cancelled carrier signal (step 520). The AM noise cancelled carrier signal is then transmitted from an antenna of the reader device (step 525), and the backscatter signal is received at the reader device in response to transmission of the AM noise cancelled carrier signal (step 530).

Abstract: Audible crosstalk can be mitigated in a low-cost three-wire device having audio capability and/or voice applications. In some embodiments, a voltage can be introduced in a microphone power supply that is approximately the same as a measured noise voltage and the resulting voltage appearing at a microphone output can be optimized to mitigate the noise voltage and, thus, the presence of crosstalk. In some embodiments, a microphone within a circuit can be isolated to mitigate crosstalk by introducing current into a circuit that is approximately the same as a measured current, but having a flow in an opposite direction.

Abstract: An apparatus for capturing images of a target object having a barcode. The apparatus includes a reflector, an LED emitting mostly invisible light, and a photodetector. The LED is configured to emit a first portion of the invisible light toward the target object directly and to emit a second portion of the invisible light toward the reflector. The reflector is configured to redirect at least some of the second portion of the invisible light toward the target object. The photodetector is configured to detect returned invisible light from the target object to generate an electrical signal.

Abstract: An imaging reader for electro-optically reading a target by image capture includes a window supported by a housing, a chassis mounted in the housing and having chassis walls bounding an optical compartment, and an imaging module in the optical compartment for capturing return light from the target through the window. A component seals the optical compartment and protects the window from shock forces. The component is mounted between the window and the chassis walls bounding an opening into the optical compartment, and surrounds a periphery of the window. The component is constituted of a compressible material that is compressed between the window and the chassis walls to isolate and seal the optical compartment from the housing.

Abstract: A barcode reader for verifying a barcode is attached to an appropriate object particularly suitable for use at a point of sale. A database of expected object signatures in a vicinity of a properly affixed barcode properly is maintained. At a point of sale, the barcode reader obtains an image of a presented barcode (possibly not the correct barcode) and at least a portion of an object to which the presented barcode is affixed. Using data encoded on the presented barcode, the database is accessed to provide an expected signature of the object in the region of the presented barcode. A comparison is made between the expected signature of the object and a sensed signature derived from the image of the object. An improper barcode can thus possibly be identified and further investigation initiated.

Abstract: An imaging module for electro-optically imaging a target, includes an energizable illuminating light source for illuminating the target with illumination light for return from the target, an energizable solid-state imager for capturing return light from the target, and a controller for energizing the imager during an exposure time period to capture the return light at a frame rate, for deenergizing the imager during a non-exposed time period, and for energizing the illuminating light source not only during the exposure time period, but also during the non-exposed time period, to produce a plurality of illumination light pulses at an illumination rate that enables the human eye to perceive the illumination light pulses as substantially continuous. The illumination rate of one or more of the illumination light pulses produced during the non-exposed time period is substantially independent and decoupled from the frame rate.
