To implement a complex math function, i.e. a math function with multiple input variables, a configurable computing array comprises at least an array of configurable computing elements. Each configurable computing element comprises at least a memory which stores a look-up table (LUT) for a math function with a single input variable.

RETENTION VALVE FOR VARIOUS PACKAGES relates to a retention valve for a range of packaging, consisting of a capsular body (1) forming an outlet duct for the product to be dispensed, the outer diameter of which is provided with means (2) for securing to the inside of the outlet in the form of a circular hole (F) of a dispensing pack (E), while its inner diameter slidably accommodates a longitudinally movable obturator (3), and the front end of which has closing means (4) for a obturator (3), while its rear end is flexibly engaged in the centre of a flexible sieve (5) and, at this point, said sieve has means for keeping the aforementioned obturator (3) pulled back in order to keep the leak-tight closing means (4) closed.

A spray head (10) for a device for dispensing a fluid product, comprising a body (11) provided with a spray hole (12), the spray head (10) comprising a connecting member (15) rigidly attached to the body (11), the connecting member (15) defining a central axial channel (16), the spray head (10) comprising at least one valve (20; 40) forming precompression means for generating a calibrated spray through the spray hole (12), an intermediate member (14) being inserted between the connecting member (15) and the body (11), the intermediate member (14) being hollow and comprising an opening (14) that opens into the connecting member (15), a sleeve (40) being mounted so as to slide in the connecting member (15) around the intermediate member (14) between an open position and a closed position, a resilient element (41) biasing the sleeve (14) to its closed position in which it closes off the opening (14), the sleeve (40) being moved towards its open position when the flow of fluid product (F) is actuated based on a predetermined pressure.

To implement a math function with multiple input variables, a configurable computing array comprises at least an array of configurable interconnects, an array of configurable logic elements, and an array of configurable computing elements. Each configurable computing element comprises at least a memory for storing a look-up table (LUT) for a math function with a single input variable.

A foamer dispenser including a mesh filter that is disposed in a mixture flow path of a jet ring to allow a mixture to pass is provided. A connecting flow path area between a liquid flow path and the mixture flow path and a connecting flow path area between an ambient air flow path and the mixture flow path have the relation 2.8S.sub.1/S.sub.23.8, and/or, a smallest flow path area of the mixture flow path is located on an immediately upstream side of the mesh filter, and the smallest flow path area and a flow path area of the mesh filter have the relation 4S.sub.4/S.sub.310.3.

A trigger head for a dispensing device for at least two substances including a pumping system to compress the substances separately and simultaneously before dispensing.

Dispenser with a liquid storage unit, a dispensing head with a perforated plate component which has at least 25 dispensing openings in a dispensing opening region, with a pre-chamber connected upstream of the dispensing openings of the perforated plate component and from which the dispensing openings are supplied, and a connecting channel which connects the liquid storage unit to the pre-chamber. The perforated plate component is fastened on the dispensing head in an edge region and the dispensing opening region is pressed into a curved form by means of a curvature body which is arranged in the pre-chamber and acts with force upon the perforated plate.

A dispensing device for dispensing a foamable product. The dispensing device comprises a valve. The valve comprises: a plug; a seat configured to receive the plug; and one or more resilient arms coupled to the plug, configured to bias the plug against the seat. The valve has a closed configuration in which the plug is received by the seat, and an open configuration in which the plug is displaced from the seat.

The present invention discloses a configurable computing array comprising three-dimensional writable memory (3D-W). It is a monolithic integrated circuit comprising an array of configurable computing elements, an array of configurable logic elements and an array of configurable interconnects. Each configurable computing element comprises at least a 3D-W array, which stores at least a portion of a look-up table (LUT) for a math function.

An application dispenser for at least one component, in particular for an adjustable dosing and/or mixing dispenser, includes a rotation element, in particular a ball for applying the at least one component, and a pump configured to load the at least one component with pressure and feed the at least one component under pressure onto the rotation element.
