A sensor system for a conveyor belt comprising a sensor stage on the conveyor belt and a stationary drive and detection stage external to the conveyor belt in the belt carryway. In an exemplary version, the sensor stage includes a capacitor sensor whose capacitance varies with the weight of a load atop a pressure platform at the belt's conveying surface. An oscillator in the drive and detection stage drives the capacitor sensor through capacitors formed when plates in the sensor stage in the advancing conveyor belt overlap stationary plates in the drive and detection stage during the belt's passage along the carryway. The corresponding plates in the belt and the carryway have different longitudinal dimensions to ensure constant plate overlap area of longer duration and despite lateral belt-tracking offset. The drive and detection stage detects the capacitance of the sensor and converts it into a weight value.

A jack assembly includes a body. The jack assembly also includes a lifting piston positioned at least partially above the body and configured to move up and down with respect to the body. The jack assembly also includes a lock collar positioned at least partially around the lifting piston. The lock collar is configured to move up and down with respect to the lifting piston in response to rotating the lock collar with respect to the lifting piston. The jack assembly also includes a load cell positioned at least partially around the lifting piston and between the body and the lock collar. The jack assembly is configured to support an object, which exerts a downward force onto the lifting piston. The downward force is transferred from the lifting piston to the lock collar to the load cell to the body. The load cell measures the downward force.

A method of handling weight data in a data processing system involves acquiring and storing weight data of an item. A verification information is generated for the item based on the weight data, where the verification information is associated to the determined weight, the generation of the verification information including one of the following steps: a) encrypting the weight data where the verification information corresponds to the encrypted weight data, or b) determining a first message authentication code where the verification information corresponds to the first message authentication code, wherein when using the weight data the validity of the weight data for the item is verified by use of the verification information and if the weight data is verified as being valid weight data, a graphic representation of the weight data is generated.

A magneto-elastically-based active force sensor, used with a tow coupling between a towed and a towing vehicle or a coupling between a vehicle body and a suspension of the vehicle, which outputs a signal useful for determining forces acting on the coupling. The outputted force information may be provided by processor-enabled embedded software algorithms that take inputs from the force sensor and other sensors, may be used by one or more vehicle systems during operating of the vehicle, such as engine, braking, stability, safety, and informational systems. The force sensor includes directionally-sensitive magnetic field sensing elements inside the sensor, and shielding may be used around the sensors to reduce the influence of external magnetic fields on the sensing elements. The force sensor may be used with different tow and vehicle weight sensing coupling devices installed on different types of automobile cars and trucks.
