  • Patent number: 10451567
    Abstract: In an X-ray inspection system (1), a reject bin (14) is split into a reject bin top (15) and a reject bin bottom (16) along a separation gap (17) which is arranged at the level of a transport section (21) of a conveyor belt loop (10) and runs uninterrupted from the outfeed opening (26) to the conveyor access opening (43) which, in turn, continues uninterrupted to the infeed opening (8). After a conveyor access door (19) has been opened and a tensioning mechanism (32) has been released, the conveyor belt loop can be taken out of the enclosure cabinet (5) by sliding the transport section (21) through the separation gap and the conveyor access opening and simultaneously slipping a return section (22) of the conveyor belt loop around the reject bin bottom.

  • Patent number: 10025555
    Abstract: Devices and methods for detecting the byte order (endianness) of a control device with which a peripheral device will exchange data. The control device initially transmits a special byte order determination data command to the peripheral device, which data command includes both a byte sequence having a byte order that can be read in any direction and still have the same value, and a specific data value that is known to both the control device and the peripheral device. Control device byte order is subsequently revealed by using the peripheral device to analyze the data value of the byte order determination data command in each of several possible byte orders to determine which byte order format results in a return of the expected specific value.

  • Patent number: 9945714
    Abstract: A method of determining the mass of an object by scanning the object in a radiographic inspection system, specifically in an X-ray scanner with the capability to take scan images at a plural number J of energy leves, has three modes or parts, namely: an initial learning mode, a normal operating mode, and a learning improvement mode. An inintial learning mode in which refernce object are scanned and their actual masses weighed and stored as reference values. A normal operating mode wherein smaple objects with unknown mass m are scanned and analyzed for compatibility with the reference values, and if found incompatible, the method switches to the learning improvement mode. A learning improvement mode in which the actual mass of the sample object found incompatible is determined by weighing and updates the stored reference values.

  • Patent number: 9599503
    Abstract: A checkweighing device, checkweighing systems employing one or more checkweighing devices, and methods of operation thereof. The checkweighing devices are designed for installation between parallel, spaced apart and vertically offset infeed and outfeed conveyors. Each checkweighing device includes a weighing cell with a weighing platform; a slide chute and at least one sorting gate for directing items either to the outfeed conveyor or to a discard receiver; and a power-actuated rake for sweeping incoming items from the infeed conveyor to the weighing platform, and sweeping weighed items from the weighing platform to the slide chute. While in no way limited to such a use, exemplary checkweighing device, system and method embodiments are well-suited for automatically checking the individual weights of small articles of high value, and/or other items that need to be weighed with high accuracy.

  • Patent number: 9587974
    Abstract: Embodiments of the invention generally relate to weighing scale diagnostic methods employing a comparison of like component operating parameters. In certain embodiments, the difference between any two current operating parameter values may be compared against a maximum allowable difference, and/or the deviation of current operating parameters from a calculated measure of central tendency may be determined and compared against a maximum allowable deviation. Alternatively or additionally, a standard statistical test for outliers may be employed. An outlying difference or deviation may be indicative of a problem with the associated component. In other embodiments, the current operating parameters of like components may be compared against calibrated parameters and any deviation of the current parameter for a given component may be compared against the total deviation to determine the percentage of deviation attributable to that component.

  • Patent number: 9518862
    Abstract: Systems and methods for remotely monitoring the rezero status of a weighing apparatus, such as a checkweigher. Remotely located interested parties may sign up for notifications related to the weighing apparatus rezero status, and the interested parties may be automatically electronically notified when certain status conditions occur. A hierarchy of notifications may be established such that not all interested parties will receive every notification. System and method embodiments may also operate to identify certain trends in rezero data and to resultantly predict future rezero faults.

  • Patent number: 9354104
    Abstract: A combination of a hardware-secured reject bin and a programmed controller that together function to create an interlock that limits access to a reject bin to only those users with specific access rights. Access is gained by entering a user ID or some other authorized reject bin user access information into the user interface of a checkweigher controller or another controller in communication with a checkweigher controller. Access attempts and events may be tracked and the removal of objects from an interlocked bin may be recorded to provide for improved object traceability.

  • Patent number: 9194737
    Abstract: Methods of determining vehicle scale health and suitability for use via weight transfer pattern analysis. Dynamically changing patterns of measurement values are seen at each load cell of a vehicle weighing scale as a vehicle enters, remains on, and leaves the scale platform thereof during a normal vehicle weighing operation. These patterns may be analyzed to provide an indication of whether a given load cell is operating properly and/or being manipulated to produce a false weight reading.

  • Patent number: 8752758
    Abstract: Systems and methods of using 2-D barcodes to provide information responsive to a particular error condition/event of, or need for operational or configuration assistance with respect to, a weighing device that is adapted to generate and display such 2-D barcode. The 2-D barcode contains a hyperlink to a context-sensitive web page that contains information relevant to the 2-D barcode. An image of the 2-D barcode is captured with a scanning device and the 2-D barcode is decoded by an appropriate scanning application of the scanning device. The scanning device is subsequently caused to request the web page as directed by the hyperlink in the 2-D barcode. The web page request is received at a server or similar location, and the requested web page is sent to the scanning device for viewing and use by a user.

  • Patent number: 8723059
    Abstract: Systems and methods for the accurate weighing of coupled-in-motion railcars carrying a flowable or otherwise displaceable material. Systems of the invention employ a scale having a pair of independent scale platforms, each of which captures weight readings while a wheel carriage of a given railcar is isolated thereon. Weight data captured by the scale platforms is analyzed and combined to determine an accurate weight for the associated railcar.

  • Publication number: 20130232431
    Abstract: A method for selecting and presenting selected media content to a consumer via a consumer display screen of a PC-based weighing scale. A scale operator is able to call up desired media content and is then permitted to select a particular portion(s) of the media content from a list of available media content responsive to the request. Upon selection, the selected media content is pushed to the consumer display screen where it replaces the content currently appearing thereon. As a transaction takes place on the scale, relevant/necessary information is presented on the consumer display screen without interruption or a reduction in size of the selected media content display. The information is presented in a built-up fashion that maximizes the amount of the consumer display screen available for presenting the selected media content.
