Accuracy-Enhanced Scanner
A portable scanner with improved user feedback provides scan data to a networked computing node via a wireless interface and the Internet. The portable scanner receives user feedback information from the networked computing node via the wireless interface and the Internet. The user feedback information indicates successful entry of the scan data into a database, or alternatively successful receipt of the scan data by the networked computing node. The portable scanner sets a scan status indicator to a final state in response to the user feedback information. Optionally, the database is a remote database that a local database is synchronized with, and/or the database is associated with the networked computing node. Optionally the portable scanner is wearable. Optionally the portable scanner is compatible with barcode and/or RFID technologies.
Modular off-platter detection assembly for use with barcode readers
A modular off-platter detection assembly for use with a barcode reader includes a housing, a first light source, a first light sensor, and a controller operatively coupled to the first light source and the first light sensor. The housing is configured to be removably mounted to the barcode reader, a frame supporting the barcode reader, or the workstation. The first light source is positioned within the housing and emits a first light along a first lateral edge of a weigh platter. The first light sensor is positioned within the housing, has a first field-of-view along the first lateral edge, and is configured to detect at least a portion of the first light reflected towards the housing. The controller is configured to provide a first alert in response to receipt of a first value from the first light sensor indicating there is an object extending across the first lateral edge.
Barcode reader with transflective mirror
Barcode readers with transflective mirrors are disclosed herein. An example barcode reader includes a housing and a window positioned within the housing, an imaging sensor and an illumination source positioned within the housing, and a transflective mirror positioned within the housing. The field-of-view of the imaging sensor is directed through the window along a first central axis of the field-of-view of the imaging sensor and the illumination pattern from the illumination source is directed through the window along a second central axis of the illumination pattern that is substantially parallel to the first central axis of the field-of-view of the imaging sensor.
TOOL CONTROL PROGRAM SYSTEM AND METHOD OF TOOL CONTROL
A system and method of a tool control program that provides real-time tracking of critical data points relating to production tools between the point of issuance to a designated user to the point of return of each production tool by the designated user, including intermediate events such as sharpening, repair and damage analysis, whereby each critical data point is capable of being linked to a unique asset number assigned to each production tool and a unique designated user number in real-time providing for management, regulatory compliance and/or employee accountability relating to each production tool. The tool control program having an integrated software relating to scanning production tools in relation to the critical data points, such that real-time data analytics can be obtained and utilized for risk management and asset visibility.
Phase Lock Loop Circuit Based Adjustment of a Measurement Time Window in an Optical Measurement System
An illustrative system may include a TDC configured to monitor for an occurrence of a photodetector output pulse during a measurement time window that is within and shorter in duration than a light pulse time period, the photodetector output pulse generated by a photodetector when the photodetector detects a photon from a light pulse having a light pulse time period; a PLL circuit for the TDC and having a PLL feedback period defined by a reference clock, the PLL circuit configured to: output a plurality of fine phase signals and output one or more signals representative of a plurality of feedback divider states during the PLL feedback period; and a precision timing circuit configured to adjust, based on one or more of the fine phase signals and/or the feedback divider states, a temporal position of the measurement time window within the light pulse time period.
Flicker mitigation for multiple interspersed illumination systems
A method of activating an illumination assembly within a symbology reader is provided, the illumination assembly having a first illumination source and a second illumination source, the symbology reader having an imaging sensor configured to operate at a predetermined framerate where each frame includes an exposure period over which the imaging sensor is active to capture image data and a non-exposure period over which the imaging sensor is not active to capture image data, the method comprising: during a first frame, activating the first illumination source during at least a portion of the respective exposure period and activating the second illumination source over at least a portion of the respective non-exposure period; and during a second frame, activating the second illumination source during at least a portion of the respective exposure period and activating the first illumination source over at least a portion of the respective non-exposure period.
INSTALLATION SUPPORT DEVICE AND INSTALLATION SUPPORT METHOD FOR STATIONARY CODE READER
Recommended installation position and posture of a stationary code reader can be proposed to a user to facilitate installation work of the code reader by the user. An installation support device for the stationary code reader acquires camera information including a camera parameter of the code reader, code information to be read, and environment information including a conveying speed of a line, determines required field of view and depth of the code reader required to read a code under an environment specified by the environment information, and determines an installation pattern which is recommended installation position and posture of the code reader that can satisfy the required field of view and depth based on the camera information and the code information.
Systems and methods for reading machine-readable marks on racks and receptacles
A method of reading machine-readable marks on a movable support and object of a sample instrument. The method includes capturing a first image of the moveable support as the moveable support moves from a first position to a second position using an image capture device; determining whether a first fiducial machine-readable mark on the moveable support is in the first image; determining, when the first fiducial machine-readable mark is in the first image, whether a first machine-readable mark on a first object coupled to the moveable support is in the first image at a predetermined position relative to the first fiducial machine-readable mark; and associating information decoded from the first machine-readable mark on the first object with a first location on the moveable support associated with the first fiducial machine-readable mark.
Aim light assemblies for use in barcode readers and methods and systems associated therewith
A method and apparatus for manipulating an aiming light of a reader to indicate the field-of-view (FOV) of an imager within the reader includes an optical element. The optical element receives the aiming light from an aiming assembly and redirect the aiming light such that the central axis of the aiming light exiting the optical element is non-coaxial with the central aiming axis of the aiming assembly at the entry of the optical element. The optical element may be configured to project an image on a target that indicates the boundary of the FOV or project an image on the target that indicates the center of the FOV.
