Abstract: Item characteristic databases, such as item weight databases are employed in a variety of checkout contexts in stores. As one example, a security weight database is often employed in a security check during self-checkout in which an item's weight is checked during bagging against a stored weight for the item. Approaches for extending such security checks for a single item or items sold in small quantities are addressed.

Abstract: 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. Fourier analysis can conveniently be applied for analyzing the acquired current data and comparing to stored calibration data to determine weight. Weight is determined without regard to the actual speed of the moving article.

Abstract: Weight is used to help identify key and ring combinations authorized to certain persons. This is done by associating a weigh scale with each storage box for key and ring combinations, all of which have different total weights. The weights of all the key and ring combinations are registered with a computer, along with authentication and storage information. Then as key and ring combinations are removed from or returned to a storage box, they are weighed on scale 25 so that a computer can compare the scale weight with a registered weight. For any discrepancy, the computer can initiate one of many security actions.

Abstract: 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).

Abstract: A method (51) for measuring the mass of an object such as a letter (10) in motion. An apparatus (12) for carrying out the present invention includes a pair of rollers (16, 18) through which a letter passes. One of the rollers (16) is driven by a motor (20) which has an associated encoder (22) to give motor positional information to a controller (24). In a method of the present invention the controller generates a ramping torque signal (44) which is provided to the motor. A friction correction curve (40) is generated and applied to the torque signal, and an average torque value (C) is determined. From the positional information provided by the encoder, acceleration (50) is derived and an inertia value is obtained by dividing the average torque (C) by the acceleration. Prior to obtaining an inertia value with a letter, an initial inertia value is obtained without a letter to get a base inertia. The base inertia is subtracted from the measured inertia with a letter to get a difference ?I.
