Provided is an overload prevention mechanism including a load receiving part provided with a flange having at least three ribs on the upper surface of the flange; a pedestal located below the load receiving part; an elastic body which has one end in contact with the load receiving part and the other end in contact with the pedestal, and which biases the load receiving part and the pedestal in such a direction that the load receiving part and the pedestal are separated from each other; and a connection member having on the lower surface thereof recessed grooves which engage with the ribs. The three or more ribs are disposed so as to restrict inclination and rattling of the load receiving part due to a load applied to the load receiving part.

The present invention relates to a weighing device (1), in particular price labelling device or checkweigher, having a scale for weighing a product in a weighing section (A.sub.W), having a conveying device (4) for transporting the product (3) along a conveying region (F) from a start position (P.sub.start) over the weighing section (A.sub.W) to a destination position (P.sub.destination). To simplify a calibration to compensate for a static-dynamic offset, the invention proposes that the weighing device (1) further has a control device (5) which is configured such that the conveying device (4) can be automatically stopped during its operation in a direction from the start position (P.sub.start) to the destination position (P.sub.destination) and then can be automatically operated in a direction from the destination position (P.sub.destination) to the start position (P.sub.start). Furthermore, the invention relates to a corresponding method for weighing a product (3).

In various example embodiments, a system and method for using a mobile device to determine a haul weight are disclosed. A method includes: providing predetermined calibration settings relating force to engine speed for a vehicle travelling at various speeds, altering accelerometer data based on filtered vehicle pitch and roll data, determining that one or more vehicle performance parameters fall within a threshold range, storing a plurality of data pairs that include longitudinal acceleration and drive force, and determining a slope of a line that linearly approximates the plurality of data pairs, the slope indicating a total weight, the total weight comprising a weight of the vehicle and a weight being hauled by the vehicle; and transmitting the total weight to a display.

A weighing bar assembly includes a hollow structural part (1), with two load cells (2) positioned therein. The assembly further includes two ground support shoes (4). Each of the load cells (2) is attached at one end to the structural part (1) by a securing block (3) and at its other end to a corresponding ground support shoe (4).

A combination scale is provided that includes a combinatorial computation unit and two operation modes; a normal operation mode, and a corrective operation mode in which correction values are decided. The correction values are for use in correcting errors of measured weight values calculated from weight signals of weight sensors. In the normal operation mode, the combinatorial computation unit corrects the measured weight values using the correction values decided in the corrective operation mode. Then, the combinatorial computation unit executes combinatorial computations based on the corrected measured weight values.

A method for optimizing the running properties of a rotating belt of a weighing belt conveyor includes, for at least one rotation of the belt, determining a unique reference position on the belt. A force signal is determined in dependence on the movement of the belt with respect to the reference position during the at least one rotation. From this force signal, the course of a deviation of the force signal from a set value as a consequence of a disruptive force is determined. At least in correspondence with the direction of the determined deviation, the mass of the belt is increased or reduced at locations in dependence on the position of the belt with respect to the reference position.

An occupant determination apparatus includes a weight sensor that senses a weight of an object on a seat of a vehicle, a lateral acceleration sensor that senses lateral acceleration of the vehicle, and a processing unit that performs an operation of occupant determination. The processing unit calculates a lateral acceleration difference that is an absolute value of a difference between first lateral acceleration at a time when the weight passes through a first load threshold value and second lateral acceleration at a time when the weight passes through a second load threshold value. The processing unit performs the occupant determination based on an occupant determination threshold value when the lateral acceleration difference is smaller than a lateral acceleration difference threshold value, and does not perform the occupant determination when the lateral acceleration difference is larger than the lateral acceleration difference threshold value.
