Disclosed is an apparatus and method for providing asymmetric oscillations to a container. The container may include a fluid, a particle, and/or a gas. A vibration driver attached to the container provides asymmetric oscillations. A controller connected to the vibration driver controls an amplitude, frequency, and shape of the asymmetric oscillations. An amplifier amplifies the asymmetric oscillations in response to the controller. A sensor disposed on the vibration driver provides feedback to the controller.

Provided are an enclosed stirrer using intermittent resonance and a method. The enclosed stirrer comprises: two pairs of parallel tension springs (1), a fixing bracket (2), an elastic cantilever beam (3), a cantilever beam pressure clamping device (6), an eccentric motor (4), an arc-shaped cushion block (5), and an enclosed container (8). The enclosed container (8) is mounted on the fixing bracket (2) by the tension spring (1). The elastic cantilever beam (3) is installed below the enclosed container (8) and is axially parallel to the enclosed container (8). One end of the elastic cantilever beam (3) is mounted on the fixing bracket (2) as a clamping end, the other end of the elastic cantilever beam (3) is connected to the eccentric motor (4) as a movable end. The arc-shaped cushion block (5) is connected above the eccentric motor (4). The arc-shaped cushion block (5) reciprocally strikes the bottom of the enclosed container (8) during operation of the eccentric motor (4).

To provide a microparticle-containing liquid dispersing device capable of dispersing microparticles containing cells, a microparticle sedimentation suppression method, a microparticle sorting or measuring device, and a microparticle sedimentation suppression vibrator. The microparticle-containing liquid dispersing device includes: a microparticle sedimentation suppression vibrator including a fixture configured to connect and hang on a bag containing a microparticle-containing liquid, the microparticle sedimentation suppression vibrator hanging the bag in a vertically downward direction; and a stand that hangs the bag.

A cosmetics mixing device for homogenizing suspensions of cosmetics includes a housing that defines an interior space. The housing is open-topped, and a block is positioned in the interior space. A plurality of recesses extends into the block from an upper face of the block. Each recess extends from proximate to a first endpoint to proximate to a second endpoint of the block. Each of a plurality of couplers is coupled to the block and is positioned in a respective recess. The coupler is configured to couple to a respective tubular container to retain the respective tubular container within the respective recess. A shaking module that is coupled to the housing and positioned in the interior space is operationally coupled to the block. The shaking module is positioned to shake the block to mix a cosmetic that is positioned in the respective tubular container.

Example implementations relate to print substance container vibration. A vibrator for a print system may comprise a motor, and a vibration shaft coupled to the motor to cause vibration to provide redistribution of print substance of a print substance container. The vibration may be caused in response to the rotation of an eccentrically loaded weight about a central axis of the vibrator.

An inner core assembly for a vibration mixer, comprising a motor assembly and a compression assembly located above the motor assembly, wherein the motor assembly comprises a vibration motor, a rotor shaft of the vibration motor is connected to the compression assembly by using an eccentric structure, the compression assembly comprises a stage, the stage is connected to a pressure plate mounting bracket by using a guiding shaft, the pressure plate mounting bracket is capable of sliding along the guiding shaft, the rotor shaft of the vibration motor rotates and drives, by using the eccentric structure, the compression assembly to perform reciprocating motion. Compared with the prior art, curved reciprocating motion of the stage is achieved through eccentric motion, which has lower structural costs, a lower failure rate, and a longer service life than a motor in the prior art.

A disposable fluid transfer and mixing device is disclosed and includes an injector support surface for receiving an injection device thereon. A lyophilized drug vial, a diluent vial and a syringe are also attached to the device. The device features fluid passageways and a manual valve that may be manipulated so that the syringe may be used to transfer diluent from the diluent vial to the lyophilized drug vial, for reconstitution of the drug. The valve may also be configured so that the reconstituted drug is transferred from the lyophilized drug vial to the injection device. An automated transfer and mixing device receives an injection device, a lyophilized drug vial and a diluent vial and transfers diluent from the diluent vial to the lyophilized drug vial and shakes or vibrates the lyophilized drug vial to reconstitute the drug. The device then transfers the reconstituted drug from the lyophilized drug vial to the injection device.
