A device for measuring forces or a weighing device includes at least one sensor, at least one force input device configured to elastically deform in relation to an external force acting on the device, and a casing coupled to the sensor and the force input device. The sensor is configured such that, when the force is applied to the device, the sensor detects the force in relation to the elastic deformation of the force input device, and the casing is configured to accommodate the sensor in the casing in at least two different positions.

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.

A system and method for dispensing a powdered pharmaceutical into a bottle is disclosed. The system includes a filler having a powder filler head and respective weight sensor, two or more draft shields, and one or more static reduction devices. In some embodiments, the system also includes one or more dust extractors. In some embodiments, the static reduction device is an active static reduction device, such as one or more static bars. The two or more draft shields may include an inner draft shield to reduce small pressure and/or airflow changes and an outer draft to reduce large pressure and/or airflow changes.

A load suspension and weighing system for a removable reservoir unit of a portable dialysis machine includes a centrally located flexure assembly. The flexure assembly includes magnets and a number of flexure rings which allow for movement of the magnets about a fixed circuit board. Sensors in the circuit board sense changes in the magnetic field as the magnets move in relation to the circuit board. The magnetic field changes produce a voltage output which is used by a processor to generate weight calculations. The top of the flexure assembly is attached to the interior of the dialysis machine. The entirety of the reservoir unit is suspended by a first internal frame that is attached to the bottom of the flexure assembly. Having a single flexure assembly positioned above the reservoir unit provides more accurate weight measurements while also preventing damage to the assembly from water spillage.

An electromagnetic coupling sensing device includes a frequency generation module, a first resonant module, a second resonant module, and an echo acquisition and processing module. The first resonant module generates a primary resonant signal based on the frequency setting signal generated by the frequency generation module. The second resonant module couples with the first resonant module through a coupling capacitance to generate a secondary resonant signal based on the primary resonance signal. The second resonant module includes a coil. A ferrite is provided in the coil and a height of the coil is higher than the ferrite. The coil is capable of carrying a weight to be measured to deform such that an intrinsic frequency of the electromagnetic coupling sensing device changes. The echo acquisition and processing module collects the secondary resonant signal and outputs a voltage signal changing according to the intrinsic frequency.
