  • Patent number: 10806410
    Abstract: A method automatically determines a weight of a patient lying on a tabletop of a patient positioning device. A motorized movement of the tabletop along at least one predeterminable axis sets the tabletop in an oscillation via an elastic drive train element, and the patient's weight is determined from a determined oscillation frequency. Therefore, the weight of a patient lying on a patient positioning device can be determined in a simple manner.

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 check weight (1) that is used to check a gravimetric measuring instrument, specifically a balance, or to check a further weight, is provided with a means of identification. This marking which is applied on the outside surface of the check weight includes a permanently affixed machine-readable identification code (2) which makes the specific weight piece individually recognizable. This opens the possibility for a method whereby an individually identifiable check weight can be traced back in time. A system for tracing check weights back in time includes one or more reader devices (6) that serve to record the marking, one or more processors (10) wherein the machine-readable identification code can be converted back into an identification code that can be electronically processed, and one or more data storage units, in particular a database (8) serving to store at least the data contained in the identification code.

  • Patent number: 8357548
    Abstract: A semiconductor wafer metrology technique comprising performing atmospheric buoyancy compensated weighing of a wafer, in which the wafer is weighed in a substantially upright condition. A vertical or near vertical wafer orientation causes the surface area in the direction of a force (weight) sensor to be reduced compared with a horizontal wafer orientation. Hence, the electrostatic force components acting in the same direction as the wafer weight force component is reduced.

  • Publication number: 20120285218
    Abstract: A system and method of validating checkweigher performance (weighing accuracy). The invention involves removing an object to be weighed from a conveyor prior to the object reaching a checkweigher to be validated, weighing the object on a static scale, reintroducing the object to the conveyor upstream of the checkweigher, weighing the object with the checkweigher, and comparing the two weight readings of the object to determine if the checkweigher is accurately weighing objects. Validation objects may be automatically removed from the conveyor by a transfer mechanism.

  • Publication number: 20120158342
    Abstract: A method for measuring the weight of impurities in a mixed volume of fibers and impurities by mechanically separating the impurities are from the fibers, whereupon some undesired fibers still remain admixed to the impurities due to imperfections of the mechanical separation. A total weight of the separated impurities and the undesired fibers is gravimetrically measured. An image of the separated impurities and the undesired fibers is created. A weight of the undesired fibers is estimated from the image. The estimated weight of the undesired fibers is subtracted from the total weight to yield a corrected weight of the impurities. The mechanical separation and the subsequent electronic correction yield a more accurate weight of the impurities.

  • Patent number: 8153913
    Abstract: A gravimetric measuring instrument has a weighing cell and a flexible, tubular-shaped encapsulation. The weighing cell has a parallel-guiding mechanism and at least one measurement transducer. The ends of the encapsulation are attached, respectively, to the stationary parallelogram leg and the movable parallelogram leg, so that at least the parallel-guiding mechanism and the measurement transducer are enclosed by the encapsulation, protecting them from dirt and humidity. In some aspects, the parallel-guiding mechanism has an adjustment region formed at one of the parallelogram legs which allows adjustment of the distance between at least one flexure pivot of the upper parallel-guiding member and a flexure pivot of the lower parallel-guiding member. This adjustment region is mechanically connected to at least one adjustment-setting area, which is arranged outside the encapsulation and allows changes to be made to the adjustment region.
