Embodiments described herein generally relate to devices, systems and methods for measuring the dose remaining in a drug delivery device that is used for delivering a dose to a patient. In some embodiments, a dose measurement system for measuring the liquid volume in a container includes a plurality of light sources which are disposed and configured to emit electromagnetic radiation toward the container. A plurality of sensors are located in the apparatus that are optically coupleable to the plurality of light sources and are disposed and configured to detect the electromagnetic radiation emitted by at least a portion of the light sources. The apparatus also includes a processing unit configured to receive data representing the portion of the detected electromagnetic radiation from each of the plurality of sensors. The processing unit is further operable to convert the received data into a signature representative of the electromagnetic radiation detected by the plurality of sensors.

A piston pump arrangement that disables operation of the pump in the absence of an inlet liquid and also to a piston pump arrangement useful to discharge liquids from at least two sources and to disable discharge of all of the liquids when supply of liquid from at least one source is empty.

A solenoid operated unit (100) for detecting and removing an undesired fluid (6) from a desired fluid (5) with diagnostic metering, comprises a unified solenoid operated pump and valve unit (70), a drainage path (40), an electrical detection system (60), a mecha-electro-magnetic detection system (80) and a junction box (190) interacting with an electronic control unit (90) comprising a PWM generator. A plunger (50) moves from up to down, a sweeping volume (28) with a cycle of a PWM electricity wave, while moving down the plunger (50) creates a negative pressure in a sweeping volume (28) and while moving up a positive pressure gets created in the sweeping volume (28) and a negative pressure gets created at a rear end (30) of a unified chamber (26), an air reliever (180) is provided for breathing.

The dosing device consists, for example, of a closure, having a closure body (1) with sealing closing means (7), which can be placed in a sealing manner on the connector. The metering means of the closure consist of just two components. There is first, seated securely in the closure body (1), a hollow cup (4) having, on the bottom side of the cup (4), a window (12) arranged in its side wall. The second component is a cap-shaped metering piston (10) having, on the upper side of the cap, a projection (5) which extends in the axial direction. This metering piston (10) with projection (5) fits into the cup (4), wherein its projection (5) covers and closes the window (12). The metering piston (10) is able to move axially in the cup (4) and its projection (5) is able to pivot to a limited degree toward the outer side of the window (12). In the pivoted-out state, it forms, together with the cup (4), an open valve which is otherwise closed.

A metering device and metering method for metering carbon dioxide flow belong to the technical field of preparation of polyurethane foam materials. The metering device of the present invention has a simple structure and a small size, can accurately control the amount of the delivered liquefied carbon dioxide; meanwhile, one end of the metering pump is connected with the sliding block, and the sliding block can move on the transverse plate, thus changing the vertical movement stroke of the piston rod and changing the flow volume of the carbon dioxide. The cylinder of the metering pump of the present invention is internally provided with the water passages, and a coolant can be filled into the water passages to keep the temperature of the carbon dioxide constant.

The invention relates to a method and device for applying a preformed portioned malleable mass, comprising: a hollow space, provided with at least one closable exit opening; a piston that can be moved back and forth in at least a part of the hollow space with at least a directional component from and to the at least one closable exit opening and preferably in a direction directed from and towards the at least one closable exit opening, which piston is movable is between at least: a retracted position in which the part of the space is released by the piston; and an ejected position in which the part of the space is fully occupied; a mass supply channel for the malleable mass exit opening onto the part of the space that is released in the retracted position of the piston; a valve for the closable exit opening which is movable between a position closing the exit opening and a position releasing the exit opening; and a supply channel for a medium, such as air, under pressure, leading through the piston to a side of the piston facing the exit opening, for bringing the hollow space under medium pressure.

The invention describes a dosing system (3) for a shear-thinning or thixotropic liquid to viscous dosing material. It comprises a nozzle (1) with a closure channel (55), within which a closure element (21) is controlled during operation by means of an automatic control unit (63) in an ejection direction (E) and/or retraction direction (R). To this end, the closure channel (55) is realized in at least one cross-section perpendicular to the ejection direction (E) and/or retraction direction (R) relative to the cross-section of the closure element (21) in the same plane to give an aperture gap (57) between the outer surface (S.sub.1) of the closure element (21) and the inner surface (S.sub.2) of the closure channel (55), which aperture gap (57) is shaped and/or dimensioned to form an outlet channel, at least in places, for the dosing material. The control unit (63) is realized to generate control signals (SS.sub.1, SS.sub.2) for different movements of the closure element (21) in at least two movement modes (M.sub.1, M.sub.2, M.sub.4, M.sub.5, M.sub.6), whereby it deliberately moves the closure element (21) during operation in order to reduce the viscosity of the dosing material in at least a region of the aperture gap (57). The invention further describes a method of manufacturing such a dosing system (3), and a dosing method that can be carried out with the dosing system (3).
