An infusion apparatus includes a housing and a chamber configured to be connected to the housing. The apparatus further includes a weight sensor coupled to a load connector connected to the housing and an optical sensor disposed in the housing. The weight sensor is configured to generate a first signal based on a measured weight of the fluid container attached to the housing in a weight-bearing configuration. The optical sensor is configured to generate a second signal based on detecting drops of the fluid traversing the chamber. The apparatus also includes a flow control mechanism to control a flow rate of the fluid into an outlet channel. The apparatus includes one or more processing devices configured to perform operations including transmitting a control signal to the flow control mechanism to adjust the flow rate.

A method can include obtaining a first weight measurement of a receptacle and obtaining a second weight measurement of the receptacle. The method can further include calculating a first difference between the first weight measurement and the second weight measurement, resulting in a reference dispensation value. The method can further include obtaining dispensation data, the dispensation data including a measured dispensation value. The measured dispensation value can correspond to a quantity of a substance dispensed from the receptacle, the quantity of the substance passing through a dispensation monitor coupled to the receptacle. The method can further include calculating a second difference between the reference dispensation value and the measured dispensation value. The method can further include determining that the second difference exceeds a threshold and adjusting the dispensation monitor in response to determining that the second difference exceeds the threshold.

A lock assembly includes at least a lock component, a lock member, and a bracket. The lock component is securable to a load cell. The lock member is configured to move into a first position to provide an unlocked state in which the lock member is disengaged from the lock component. In the unlocked state, the load cell is physically unsecured from the lock member and enabled to operate. The lock member is configured to move into a second position to provide a locked state in which the lock member is engaged with the lock component. In the locked state, the load cell is physically secured to the lock member via the lock component. The bracket is configured to support the lock member in relation to the lock component.

Various embodiments of the present disclosure are directed to measuring methods for determining a flow rate of a process gas, contained in a gas pressure vessel charged with overpressure, escaping from the gas pressure vessel. In one example embodiment, the method includes: exerting a vessel weight force from the gas pressure vessel together with the contained process gas; compensating for the vessel weight force by means of a counterweight force exerted by a counterweight, or the counterweight force by means of the vessel weight force exerted by the counterweight, at least partially to a resultant measured weight force; determining the measured weight force at at least two points in time; and determining the flow rate of the process gas using the measured weight force determined at the at least two points in time.

The present application relates to a device for dispensing a determined weight of a cosmetic product into a receptacle from a reservoir, the device comprising at least one electromechanical member capable of moving an amount of cosmetic product from said reservoir installed in the device to a dispensing zone of said device where said amount of product may be transferred through a nozzle into the interior of the receptacle received in said dispensing zone, the device comprising a controller configured to deliver a control signal to the electromechanical member according to an error with respect to a setpoint corresponding to the determined weight of cosmetic product to be delivered, said error being determined on the basis of a weighing datum obtained by at least one weighing cell for the reservoir installed in the receiving zone, the device being characterized in that the controller is a reinforcement-learning controller.

A substance weighing system and method are provided. The system includes a balance, and axle, a substance dish, an axle support bracket, and an axle rotator. The axle has a rotational axis extending between first and second axial ends. The substance dish is fixed to the axle adjacent the first axial end. The axle support bracket mounts the axle relative to the balance and in a manner that permits the axle to rotate about its rotational axis. The axle rotator has a motor and a clutch mechanism. The clutch mechanism communicates with the motor and is configured to cause the axle to rotate between first and second rotational positions. In the first rotational position the substance dish is positioned to hold a substance, and the axle rotator is in a contactless state. In the second rotational position, the substance dish is positioned to release the substance.
