A positioning method for positioning a first device and a second device separated from the first device is described. The second device is moved so as to approach the first device, a first mark on the first device and a second mark on the second device are imaged, and information is output based on the imaging the first mark and the second mark.

One or more embodiments relate to systems and methods for mixing of two or more fluids using a multi-chamber manifold. One or more embodiments relate to optimal mixing.

A dispersing device is provided by which a dispersion with a high yield and a proper dispersing process can be carried out. The dispersing device causes a mixture of a slurry or a liquid to flow by centrifugal force toward an outer circumference between a rotor and a stator. It comprises a container, a cover assembly that closes an upper opening of the container, a stator that is fixed under the cover assembly, a rotor that is disposed to face a lower surface of the stator, and an assembly for supplying the mixture that stores an unprocessed mixture to be supplied to a gap between the rotor and the stator. The assembly for supplying the mixture has a body, a first member for injecting the mixture, and a second member for injecting the mixture.

The invention provides a mixing container comprising: a liquid holding vessel having first and second chambers each for holding a different liquid; a mixing unit having a first valve and a second adjustable valve, the second adjustable valve having an opening that can be partially closed to permit a pre-determined portion of liquid from each chamber to be dispensed when pouring from the mixing container; and the second valve including a series of teeth around the periphery thereof for engaging an adjustment wheel in the mixing unit to open or close the opening in the second adjustable valve.

A system forms a cosmetic composition. The system includes a dispensing arrangement in selective fluid communication with a plurality of dispensing dosing receptacles mounted on a movable carousel. The dispensing arrangement is configured to selectively dispense a plurality of the booster compositions together with a base composition corresponding to a formulation corresponding to a compatibility profile and consumer skin conditions to form a stable composition having efficacious concentrations of active ingredients into a receiving receptacle.

A light emitting device mixer includes at least two bowl feeders, each including a bowl capable of holding workpieces, and a driving unit capable of causing vibration to the bowl. The bowl feeders include a moving passage through which the workpieces may move from one bowl feeder to an adjacent bowl feeder.

An apparatus for mixing bone cement for use in orthopedic surgeries includes a mixing region and an agitator for mix the cement ingredients. A temperature sensing means of apparatus determines when that the cement mix can no longer be used. The apparatus can be operated or acted on by a power tool for the mixing of the bone cement. The power tool and/or mixing apparatus may include a mechanical torque limiter that inhibits the agitator as a result of mixing torque exceeding a threshold value. A timer of the apparatus may be started by a sensor of the apparatus or by the user in response to a mechanical torque value. When the timer is complete, a cue by the apparatus signals to the user that the mixed cement is ready and able to be applied.

An example fluid management system for generating a fluid for a treatment operation may include a mixer and a first portable container disposed proximate to and elevated above the mixer. The first portable container may hold dry chemical additives. A feeder may be positioned below the first portable container to direct dry chemical additives from the first portable container to the mixer. The system may also include a first pump to provide fluid to the mixer from a fluid source.

A mixing apparatus, comprising a drive unit (1) with a drive (10) and a shaft (11) which is pivotable about a pivot axis (A) and which is operatively connected to the drive (10), a pivot receptacle (2) which is arranged on the shaft (11), wherein the pivot axis (A) is substantially horizontally aligned, wherein the pivot receptacle (2) comprises a base (20) on which receptacles (21, 22) are provided which extend away from the base (20) and into which holders (3) for containers (7) are insertable.
