A dispensing system (2000), includes a container (900) containing a flowable base formulation (910) to be dispensed, an additive mixing device (2004), and an actuable pump engine (2002) which draws the flowable base formulation from the container and pumps it through the mixing device. The additive mixing device includes a body (2022) with an internal cavity (2052), an additive ingredient (2054) within the cavity, and a flow path/mixing chamber (2058) between an input and an output. With each pump of the device (2004) the additive ingredient is introduced into, and mixed with, a flow of the base formulation traveling through the mixing device. Multiple additive mixing devices (2004) may be interchangeable for different formulations, and the mixing devices may be refillable.

A system for dispensing at least one makeup product, including a cup and a dispenser for filling the cup from the bottom with at least one product, the cup being secured to the dispenser at least while it is being filled with said product. The method for dispensing and evaluating makeup, including the steps of: allowing a video link to be established, for example over the Internet, from a camera at a first site to a second site, allowing the second site to operate either directly or indirectly a dispenser of such a dispensing system, present at the first site, this dispenser making it possible to vary the colour of mixture dispensed, and allowing a person present at the first site to apply the mixture dispensed and to send to the second site a corresponding image, so as to receive in return information relating to the result of the makeup.

System for dispensing a makeup product, having a dispenser (11) that receives at least two cartridges (30), each one having a reservoir containing a base product, the latter leaving the cartridge via an outlet channel (52) of the cartridge, this outlet channel opening out at the outside of the dispenser or near the external surface thereof.

A dispensing system has a dispenser for delivering a variable colour mixture, and a computer system having a touch screen on which the mixture colour can be displayed, and a selection movable on the screen, to vary the dispensed mixture colour. A method for learning to use such a dispensing system having a dispenser allows a colour mixture to be dispensed, and a computer system, making it possible to select a colour and to memorize data, including: selecting at least one colour with the aid of a computer system interface, delivering, with the aid of the dispenser, at least one selected colour mixture, evaluating the one or more dispensed mixtures after application to at least one face zone, memorizing the at least one mixture characteristics, in particular a mixture that the user wishes to be able to recover, and of at least one zone on which it has been tested.

An ordered, 3-dimensional, micro-scale, open-cellular truss structure including interconnected hollow polymer tubes. The hollow micro-truss structure separates two fluid volumes which can be independently pressurized or depressurized to control flow, or materials properties, or both. Applications for this invention include deployable structures, inflatable structures, flow control, and vented padding.

A method for controlling fluid ratio accuracy during a dual flow injection with a powered injection system is described. The method includes predicting a first capacitance volume of a first syringe comprising a first medical fluid and a second capacitance volume of a second syringe comprising a second medical fluid with a first capacitance correction factor and a second capacitance correction factor, respectively, selecting a ratio of the first medical fluid and the second medical fluid to be administered to a patient in the dual flow injection, determining a relative acceleration ratio of a first piston of the first syringe and a second piston of a second syringe based on the predicted first capacitance volume and the predicted second capacitance volume, wherein the relative acceleration ratio is selected to maintain the selected ratio of the first medical fluid and the second medical fluid during the dual flow injection, and injecting a mixture of a first medical fluid and a second medical fluid having the selected ratio with the powered injection system.

A fluid path set includes a first fluid line having a proximal end fluidly connectable to a source of a first fluid and a second fluid line having a proximal end fluidly connectable to a source of a second fluid. A flow mixing device is in fluid communication with distal ends of the first and second fluid lines. The flow mixing device includes a housing, a first fluid port provided for receiving the first fluid, and a second fluid port for receiving the second fluid. A mixing chamber is disposed within the housing and is in fluid communication with the first and second fluid ports. A third fluid port in fluid communication with the mixing chamber for discharging a mixed solution of the first and second fluids. A turbulent flow inducing member is disposed within the mixing chamber for promoting turbulent mixing of the first and second fluids.

A structure including a hollow porous material with an architected fluid interface to the hollow porous material and methods of forming the same. The architected fluid interface may be in the form of a manifold with tapered openings, each providing a gradually narrowing transition to the hollow channels within which fluid may flow through the hollow porous material. The material may be formed by forming an open-celled sacrificial scaffold, immersing one surface of the open-celled sacrificial scaffold in a bonding agent, attaching a face sheet to the surface to form a sacrificial scaffold assembly, coating the assembly with a coating material, and removing the sacrificial scaffold assembly.
