    摘要: Methods and apparatus for weighing an article, such as a mail piece, while the article is moving at high speed. An article (900) is received from an intake transport (1200), and gripped in a weighing station (1310), in between a capstan roller and a pinch roller (1316), which are synchronized to minimize slipping. A first precision servo system (1252, 1250) alters the speed of the article, and in the process acquires torque data for storage and analysis (1212, 1282). A second precision servo system (1260,1330) applies a constant force, via a tension arm (1320), urging the pinch roller (1316) against the capstan roller, independently of the thickness of the mail piece. Active electronic damping (1900) reduces oscillation when an inconsistency in thickness of the article is encountered during weighing. The damping force is subtracted from the capstan motor torque data for improved accuracy (FIG. 20B).

    摘要: A weighing assembly (100,500,600) includes a portable computing device (“PCC”) (112) such as a smart phone, pad computer, laptop computer, or the like. The weighing assembly utilizes one or more features of the portable computing device in order to weigh an item, under control of a scale application program or “app” executable in the portable computing device. Some embodiments may utilize an internal barometric pressure sensor of the PCC. Other embodiments may utilize orientation or position sensors of the PCC for weighing an item. Other embodiments may utilize a compressible foot element (1004), all for weighing an item. Preferably, a user interface (114) of the PCC, such as a touch screen, may be used to interact with the scale application program for calibration and other functions.

    摘要: Weighing system (FIG. 3, FIG. 6) to weigh items, parcels and the like while they are moving, for example, on a conveyor. A servo amplifier (14) and servo controller (20) are arranged to drive a servo motor in a feedback (15) configuration, and acquire torque sensing signals (17) responsive to commanded acceleration of the conveyor while the item(s) are on board. Preferably, constant acceleration of the item(s) is realized during one or more measurement intervals, and mass is derived by a processor (30) based on the measurement data (FIG. 5). Other embodiments are described for weighing granular and slurry materials (FIG. 7) and for weighing multiple, potentially overlapping, parcels in motion (FIG. 8).
