The present invention concerns a method and an apparatus for gravimetric metering of a powdery bulk material, said system comprising a storage container accommodating the bulk material, a feeding pipe for feeding bulk material from the storage container to a dosing container, a dosing discharge device for continuously discharging bulk material from the dosing container to a discharge pipe and on to a discharge line, wherein said dosing container is mounted on at least one weighing cell, and wherein the feeding pipe is provided with a first flexible tube member and the discharge pipe is provided with a second flexible tube member, and wherein the first flexible tube member comprises a first compensator and a second compensator with a tubular member there between.

A method for calculating the quantity of goods based on weighing includes the following steps: Step 1, Weight Conversion; accurately convert the weighing reading to the corresponding weight value W; Step 2, Weight Scaling; that is, the conversion of weight units; Step 3, Zero Point Correction; calibrate the weight reading; Step 4, Tare; remove the weight of non-goods objects in the weight value; Step 5, Anti-Mutation Filtering; anti-mutation filtering on the weight value; Step 6, Quantity Conversion; convert the weight value after calibration and correction of steps 1 to 5 above into the approximate (rough) quantity of the goods; Step 7, Quantity Calibration; calibrate the rough quantity of the above-mentioned goods.

The present invention relates to a system (1a; 1b; 1c; 1d; 1e) for preparing foods (100), comprising a housing (10) for receiving the food (100), a recognition device (20) for recognizing at least one food carrier (200) couplable with the system (1a; 1b; 1c; 1d; 1e), and thereby recognizing the weight of the food carrier (200), as well as a determining device (40) for determining the tare weight of the food based on the detected weight of the food carrier (200).

A virtual weight value is set, and a dummy run mode is set and activated. Then, a zero point, reference value used to calculate the weight value of articles to be weighed in each weighing hopper, is corrected based on the virtual weight value. This enables a dummy run of a combination scale to be performed with the actually empty weighing hopper being assumed to contain the articles equivalent to the virtual weight value.

A patient support apparatus includes detectors and a controller operable to automatically update a tare weight for use in determining a true patient weight. The detectors are configured to produce signals indicating a presence or absence of a corresponding removable component. The controller is configured to determine weights of each and every removable component on the patient support apparatus and store each weight in a memory. The controller is further configured to receive the signals produced by the detectors and detect any addition or removal of removable components of the patient support apparatus, update the tare weight, and determine a weight of a patient being supported on the patient support apparatus.

An apparatus or method for weighing and/or measuring the flow rate of quantity of a particulate flowing out of a hopper wherein the hopper is isolated from the other components of the apparatus. The apparatus and method are adapted to generate a decoupling point boundary that demarcates the total amount of particulate in the hopper into portions that are not fully supported and portions that are fully supported by the hopper. The particulate is in continuous contact with itself from the inlet to the outlet, with the particulate contained between the isolated hopper and the rest of the components of the system by a flexible coupling or some other method of containment. The invention has the advantages of higher accuracy, decreased cost and complexity, and greater reliability than other solid particulate weighing systems of the prior art, particularly when dealing with low density particulates.
