Abstract: A method and apparatus for projecting illumination patterns from barcode readers. The apparatus includes a housing, an invisible illumination light source, and a visible illumination light source. The housing comprises a first window located in a generally horizontal plane and a second window located in a generally upright plane that intersects the generally horizontal plane. The invisible illumination light source is operative to project an invisible illumination pattern that is at least partially incident upon the first window or the second window after the invisible illumination pattern is projected out of the housing. The visible illumination light source operative to project a visible illumination pattern out of the housing, and the visible illumination pattern has a visible center ray propagating in a direction different from the invisible center ray of the invisible illumination pattern.
Abstract: An apparatus for and method of electro-optically reading targets arbitrarily oriented in a workstation, such as a dual window workstation, employs a solid-state imager for capturing return light from the targets over a field of view. The imager has an array of sensors arranged along mutually perpendicular array axes. An optical system splits the field of view into a plurality of subfields of view that extend through a workstation window to a target. One subfield is optically configured to enable the imager to capture light from the target along one array axis. Another subfield is optically configured to enable the imager to capture light from the target along the other array axis. A controller processes the captured light in both the one and the other subfields to enable the reading of the arbitrarily oriented target in the workstation independently of target orientation relative to the array axes.
Abstract: An imaging reader for, and a method of, imaging symbols of different symbologies and a receipt acknowledgment, include a solid-state imager having an array of image sensors for capturing return light from the symbols of different symbologies and the receipt acknowledgment over a field of view, and a controller operatively connected to the imager. The controller is automatically configured for detecting a symbol having a specific symbology, for decoding the symbol having the specific symbology, for processing the receipt acknowledgment only when the symbol having the specific symbology has been detected and decoded, and for decoding symbols having symbologies different from the specific symbology when the symbol having the specific symbology has not been detected.
Abstract: Infrared light, which is non-readily visible, illuminates at least part of a field of view containing indicia to be electro-optically read. Visible light illuminates another field of view containing the same indicia. The indicia is read by image capture by the illumination light from one of the illuminated fields of view. The use of IR light minimizes an adverse reaction due to only using bright visible light. The use of visible light enables thermally printed indicia, which is not readily readable by IR light, to be read.

Abstract: Wireless networking systems and methods are provided for “staging” a wireless communication device (WCD). The WCD is designed to communicate over the air with a wireless communication station via RF signals. Network infrastructure (NI) that receives a call from the WCD (via the wireless communication station), can authenticate the WCD. Once authenticated, the NI can communicate an RF signal that includes the encrypted staging data to the WCD over an RF channel. The staging data can include settings for the WCD and/or a list of software packages to be installed on the WCD and their respective server locations. When the WCD receives the RF signal, the WCD can convert (e.g., decode) the received RF signal to generate digital data. The WCD can then decrypt the digital data to generate decrypted staging data that can be used to stage the WCD.

Abstract: In an electro-optical reader, an aiming or a scanning laser has a laser chip and a monitor photodiode. Output power of a laser beam emitted by the laser is regulated by a feedback circuit for maintaining substantially constant the laser beam output power during normal operation, a disabling circuit for disabling the feedback circuit, a drive circuit for driving the chip with a drive current when the feedback circuit is disabled, and for concomitantly generating a photodiode output voltage, a current modification circuit for modifying the drive current by a predetermined current with a concomitant change in the photodiode output voltage when the feedback circuit is disabled, and a control circuit for monitoring the change in the photodiode output voltage, for determining whether the change in the photodiode output voltage is sufficient to indicate an over-power condition, and for interrupting power to the chip when the over-power condition is indicated.

Abstract: A programmable controller and software that monitors periods an RF transmitter is active and a output power level during those periods of activity. These two values are multiplied together and accumulated over time to provide a value for the RF emissions for some period. A limit is set for the RF emissions for any period and if the RF emissions exceeds (or is expected to exceed given the current rate) the set limit, the system limits the subsequent emissions to not exceed the set limit. This reduction in emissions rate come at the cost of a small performance reduction.

Abstract: Targets to be electro-optically read by image capture are illuminated with illumination light emitted from an illumination light source and directed along an illumination path through a window to the targets, and return light from the targets is captured through the window and projected along an imaging path to an array of light sensors of an imaging system. An optical element is located in both the illumination path and the imaging path, and has a light-reflecting, non-diffusing portion for directing the captured return light incident on the light-reflecting portion along a folded imaging path to the array, and a light-diffusing portion for diffusing the illumination light incident on the light-diffusing portion along a folded illumination path to scatter and blur an image of the illumination light source, to increase an apparent size of the illumination light source, and to reduce a perceived brightness of the illumination light source.

Abstract: Output power of a laser beam emitted by a laser in an electro-optical reader is regulated by storing a killswitch byte in non-volatile memory, and by checking whether the killswitch byte is in a default state or a kill state prior to performing reading. A controller detects a fault condition and responsively changes the killswitch byte to the kill state, in order to permanently deenergize the laser and to maintain the laser permanently deenergized after the killswitch byte has been changed to the kill state.

Abstract: A method and device for non-echo ultrasonic Doppler used for corrected inertial navigation includes providing at least one ultrasonic emitter within an environment, each emitter configured for transmitting an ultrasonic tone of a predefined frequency. An initial location of the mobile device is established within the environment. Dead reckoning procedures are initiated using sensors within the mobile device. The device receives at least one ultrasonic tone from an emitter, and converts the at least one ultrasonic tone into a digital waveform. The device determines at least one peak frequency of the digital waveform, and subtracts the at least one peak frequency from each predefined frequency to determine at least one Doppler shift, which is used for correcting the dead reckoning of the mobile device.
Abstract: A lightpipe, which is mounted on one chassis part of an imaging module of an imaging reader, optically modifies an aiming beam emitted by an aiming laser, which is mounted on another chassis part of the imaging module, to generate and shape an aiming light pattern on a target. In one embodiment, at least one, or both, of the chassis parts are movable relative to each other to spatially adjust the aiming light pattern relative to an imaging field of view. In another embodiment, the aiming laser and the lightpipe are received in respective pockets of the chassis parts with clearance, and are adjustably fixed in place to spatially adjust the aiming light pattern relative to the imaging field of view.
