  • Apparatus and method for detecting and correcting read disturb errors on a flash memory
    Patent number: 9811415
    Abstract: An application executed on a device reads a portion of a memory during one of an initialization operation and a regular read operation. The application may trigger a preventative read operation during at least one regular read operation. During the preventative read operation the application selects at least one block and at least one page for the preventative read operation. The application determines a cadence for the preventative read operation. The application obtains an error correction code (ECC) status for the portion of the memory, determines if a number of errors associated with the portion is greater than a predefined ECC threshold and performs a correction, responsive to determining that a number of errors associated with the portion is greater than a predefined ECC threshold.

  • Application for and method of preventing overhanging weighing platter of scale from tipping at product checkout system and method of mounting and removing the weighing platter without tools
    Patent number: 9797766
    Abstract: A checkout system includes a workstation having a data capture arrangement for capturing through a horizontal window a target associated with a product to identify the product being checked out at the workstation, and a scale for weighing the product at the workstation. The scale has a scale mechanism, and a weighing platter on which the product is placed for weighing. The weighing platter is integrated with the horizontal window and overlies the scale mechanism. The weighing platter projects past the scale mechanism and has a front end that overhangs the scale mechanism. Non-threaded, interlocking connectors, which are provided on the weighing platter and the scale mechanism, prevent the weighing platter from tipping if a force is exerted on the front end of the weighing platter. The weighing platter is mounted on, and removed from, the scale mechanism without the aid of tools.

  • System for and method of estimating bearings of radio frequency identification (RFID) tags that return RFID receive signals whose power is below a predetermined threshold
    Patent number: 9797979
    Abstract: An RFID tag reading system and method estimate bearings of RFID tags. When the RSSI of a primary and/or secondary RFID receive signal is below a threshold, a primary receive beam is steered in a limited scan to an array of locations distributed around the location at which the RSSI of the primary receive signal is a maximum, and the RSSI of the primary receive signal is recorded at each location. The recorded RSSIs are processed to determine an effective weighted center of distribution of the recorded RSSIs, and the bearing for the tag based on the weighted center of distribution is thus estimated.

  • Imaging module and reader for, and method of, reading targets by image capture with a substantially constant resolution over an extended range of working distances
    Patent number: 9798912
    Abstract: Targets are read by image capture with a substantially constant resolution over an extended range of working distances. Return light returning from a far-out target located at a far-out working distance is sensed by an array of pixels over a relatively narrow field of view, and over a relatively wide field of view when a close-in target is located at a close-in working distance. A controller processes the sensed return light from the far-out target only from a set of the pixels located in a central region of the array. For the close-in target, the controller groups all the pixels into bins, each bin having a plurality of the pixels, and processes the sensed return light from the close-in target from each of the bins.

  • Arrangement for, and method of, expeditiously adjusting reading parameters of an imaging reader based on target distance
    Patent number: 9800749
    Abstract: A distance to a target to be read by image capture over a range of working distances is determined by directing an aiming light spot along an aiming axis to the target, and by capturing a first image of the target containing the aiming light spot, and by capturing a second image of the target without the aiming light spot. Each image is captured in a frame over a field of view having an imaging axis offset from the aiming axis. An image pre-processor compares first image data from the first image with second image data from the second image over a common fractional region of both frames to obtain a position of the aiming light spot in the first image, and determines the distance to the target based on the position of the aiming light spot in the first image.

  • Ultrasonic locationing system using a dual phase pulse
    Patent number: 9791546
    Abstract: An ultrasonic locationing system using a dual phase pulse includes an emitter emitting two consecutive frequency bursts, each having a different phase, within one ultrasonic pulse. A receiver microphone receives the ultrasonic pulse, and a processor runs an amplitude-based detection algorithm on the pulse for a band of frequencies of interest and detects a first burst of the pulse within the proper frequency band and having an amplitude exceeding a threshold. Whereupon, the processor determines a relative phase difference between the first burst and a second burst of the pulse and determines whether the relative phase difference is within a predetermined acceptance window, indicating that the pulse is valid for use in locationing the emitter and associated mobile device.

  • System for, and method of, controlling illumination of direct part marking (DPM) targets to be read by image capture
    Patent number: 9792477
    Abstract: An array of pixels of a solid-state imaging sensor having a rolling shutter is sequentially exposed to capture images from an illuminated DPM target over successive frames for image capture by an imaging reader. The DPM target is illuminated at an elevated output power level for a fractional time period of a frame, and is not illuminated for at least a portion of a remaining time period of the frame for increased energy efficiency. Only a sub-array of the pixels is exposed during the fractional time period in which the DPM target is being illuminated at the elevated output power level.
