A liquid dispensing apparatus includes a mounting unit on which a liquid discharging device is mounted, a driving circuit to supply driving power to an actuator of the liquid discharging device mounted on the mounting unit, and a controller configured to supply a first control signal to the driving circuit to drive the actuator of the liquid discharging device to discharge a liquid, and supply a second control signal to the driving circuit after a discharge of the liquid to cause the driving circuit to damage the actuator.

A system and method for collecting produced fluid from a laboratory test chamber using a plurality of syringe pumps, wherein the pressure is selectively controlled during the collecting, and the pressure is selectively reduced prior to expelling the produced fluid to one or more collection flasks.

Described and shown is a method for operating a flowmeter (1) having a measuring tube (2), wherein the flow (d) of a medium (4) through the measuring tube (2) is measured. A continuous dwell time of the measured flow (d) greater than or equal to a flow threshold (d.sub.s) is assigned to a flow interval (t.sub.D,1, t.sub.D,2) and a flow volume (V.sub.1, V.sub.2) is determined from the measured flow (d) in the flow interval (t.sub.D,1, t.sub.D,2). In each case, a continuous dwell time of the measured flow (d) less than the flow threshold (d.sub.s) is assigned to a zero flow interval (t.sub.N,1). In each case, a deviation volume of the flow volume (V.sub.1, V.sub.2) in one of the flow intervals (t.sub.D,1, t.sub.D,2) from a reference flow volume is determined and the deviation volume is compared to a threshold deviation volume. If the deviation volume in one of the flow intervals (t.sub.D,1, t.sub.D,2) is less than the threshold deviation volume, a zero flow through the measuring tube (2) is determined and compensated using the measured flow (d) in the zero flow interval (t.sub.N,1) directly preceding the flow interval (t.sub.D,1, t.sub.D,2).

A controlled environment enclosure comprises a robotic arm manipulation system used to protect and unprotect a fluid path and a swab within the controlled environment enclosure. The apparatus allows the fluid path to be protected against dangerous decontamination vapors and chemicals before the controlled environment enclosure is decontaminated. The apparatus allows the fluid path to be unprotected without the use of gloves or other means that degrade the integrity of the controlled environment enclosure when decontamination is completed. The apparatus and method allow for the protecting, unprotecting and decontaminating sequences to be automated. In some embodiments the fluid path comprises a fill needle that can removably and aseptically be sealed with a disposable monolithic injection moulded polymeric fill needle sheath. The apparatus and method further allow for the use of a swab disposed in a swab holder that is aseptically and removably sealable to a swab cap to protect the swab against decontamination vapors.

A device for measuring and dispensing predetermined volumes of dry powdered or dry granular materials, and methods for using the device are disclosed. The device comprises: a rotatable cap, a rotatable measuring cylinder, a rotatable cylindrical fill ring; and a base cylinder, such that the rotatable cap, the rotatable measuring cylinder, the rotatable cylindrical fill ring; and the base cylinder are mechanically or physically attached or joined, while preserving their operational, rotatable, releasable, or stationary functionality. A rotatable leaf partition and a blocker form a measuring volume between them within a predetermined volume from teaspoon (tsp.), tsp, 1 tsp, or 1 tablespoon (tbsp.). A minimum measuring volume may be formed in a hollow cylindrical measuring compartment by creating a cavity that provides reproducible measurement of the granules or powders within +/10% by volume.

A compact spraying device (10) connectable to a surface and for spraying a fluid comprises a housing (16) with an inlet (20), a pump (28) in fluid communication with the inlet (20), a retractable nozzle (24) in fluid communication with the pump (28), a nozzle cover (22) and a drive system (30). The retractable nozzle (24) selectively extends forward relative to a front side of the housing (16) into a spraying position for spraying the fluid and retracts inside the housing to a retracted position when not spraying. The nozzle cover (22) is selectively moveable from a closed position in which the cover (22) covers the nozzle (24) when the nozzle (24) is in a retracted position, to an open position in which the cover (22) moves to allow the nozzle (24) to extend into the spraying position. The drive system (30) moves the retractable nozzle (24) and the nozzle cover (22) and operates the pump (28).

A fluid dispensing device having a flexible fluid pouch and a dispensing assembly, the dispensing assembly having a top piece and a bottom piece, the top piece having a flexible actuator including a flexible dome and a flexible flange extension, the bottom piece having a bottom portion of a pump chamber, a pump chamber inlet, a chamber inlet valve, and a bottom portion of an outlet valve, the top piece and the bottom piece mated together to form a pump chamber and an outlet valve, the device configured to allow bidirectional fluid flow through either or both inlet and outlet valves, and to dispense a volume of fluid that is less than the volume of the pump chamber. The flexible pouch may have a single opening or two openings. In the case of a single opening, the entire dispensing assembly is in the interior of the pouch. In the case of two openings, only the flexible dome extends to the exterior of the pouch. The outlet valve is configured so that the more pressure that is applied to the flexible fluid pouch, the more tightly the outlet valve seals.

An individual serving size food dispenser includes a casing defining an interior volume configured for receipt of bulk food. An opening of the casing is positioned proximate a bottom portion of the interior volume. An auger is disposed within the interior volume of the casing. The auger includes a first flighting portion and a second flighting portion. The first and second flighting portions are wound in opposite directions. An auger motor is coupled to the auger such that the auger motor is operable to rotate the auger within the interior volume of the casing. A door assembly is positioned proximate the opening of the casing. The door assembly is configured for selectively opening to dispense bulk food from the opening of the casing.

A display device (3) on a liquid dispenser (1), the display device having at least one display element (4) and a drive device (5) for moving the display element (4) between an initial position and a display position. The drive device (5) is provided with an interface (6), via which the drive device (5) can be connected to a dispensing device (2) of the liquid dispenser (1) such that the drive device (5) is automatically activated by the actuation of the dispensing device (2) of the liquid dispenser (1).
