A vibratory drive system comprises a rotatable drive shaft and an out-of-balance wheel that is coaxial with and rotatable relative to the drive shaft. A rotary transmission system couples the drive shaft to the wheel in order to transmit rotational movement of the drive shaft to the wheel. The rotary transmission system comprises a shaft gear, a wheel gear, and intermediate gears coupling the shaft gear to the wheel gear. The intermediate gears are carried by a gear carrier that is rotatable relative to the drive shaft, and are rotatable with respect to the gear carrier. The arrangement allows the phase angle of the out-of-balance wheel to be adjusted with respect to the drive shaft.

A motovibrator with continuous adjustment of the angular offset of the eccentric masses includes a substantially box containment body which accommodates electric motor elements which have a stator that is integral with the body and a rotor for the rotational actuation of a shaft about its own longitudinal axis. The opposite ends of the shaft protrude from the body and are each associated with at least one respective eccentric mass. The shaft includes a main section and a secondary section mutually aligned along the longitudinal axis, the main section being actuated rotationally directly by the rotor, and are coupled rotationally by interposition of transmission elements.

A pedal-type vibrational apparatus includes a seat body, a pedal assembly, a gear plate assembly, a drive assembly and an eccentric assembly, like a lever structure. By treading the pedal assembly, the gear plate assembly drives the drive assembly to rotate. The drive assembly is connected with the eccentric assembly. The user can fully exercise the muscles of the body during exercise, and the vibrational effect generated by the eccentric assembly can stimulate the acupuncture points of the body to improve the blood circulation. The left and right pedals can be treaded in turn to continuously drive a gear to rotate in the same direction so as to achieve the effect of acceleration and to enhance vibrations.

A vibrational rehabilitation device includes two drive assemblies, an eccentric assembly, and two half housings. Each drive assembly includes a driving wheel assembly and a driven wheel assembly. The driving wheel assembly has a driving wheel and a driving shaft. The driving shaft is mounted to a center of the driving wheel. A grip member is provided at one side of the driving shaft opposite the driving wheel. The driven wheel assembly includes a first driven wheel and a second driven wheel. The first driven wheel is connected with the driving wheel and driven by the driving wheel. The second driven wheel is coaxially disposed with the first driven wheel. The eccentric assembly includes two transmission wheels at two sides thereof and an eccentric block sandwiched between the two transmission wheels. The drive assemblies and the eccentric assembly are mounted in the housings.

A massage system for a seat of a vehicle includes a drive motor, a sliding member having a hollow pillar shape, a first end of the sliding member being blocked by a plate member and a second end of the sliding member being opened, a housing member having a hollow pillar shape, a first end of the housing member being blocked by a partition and a second end of the housing member being opened, and a drive gear module operably connected to the drive motor, wherein at least one roller member is extended toward the housing member at an edge of the plate member, and at least one cam protruding toward the sliding member is formed at a circumference of the partition, wherein a cam profile is formed at a surface of the cam.

The present invention relates to a system for performing assays on a solid phase to measure the level of analyte in a sample. Such a system may perform immunoassays using electrochemiluminescence (ECL) including a counterbalanced orbital shaking apparatus for assay consumables.

A motovibrator with continuous adjustment of the angular offset of the eccentric masses includes a substantially box containment body which accommodates electric motor elements which have a stator that is integral with the body and a rotor for the rotational actuation of a shaft about its own longitudinal axis. The opposite ends of the shaft protrude from the body and are each associated with at least one respective eccentric mass. The shaft includes a main section and a secondary section mutually aligned along the longitudinal axis, the main section being actuated rotationally directly by the rotor, and are coupled rotationally by interposition of transmission elements.

A dynamic imbalanced force generator includes a pair of eccentric masses and a shaft frame. The generator further includes at least one support plate of a motor arranged radially with respect to the shaft frame, and a gear system. A second imbalance is arranged between a first imbalance and the shaft frame, and coaxially with respect to the first imbalance. At least one motor is supported by the plate and engaged with at least one of the first and second imbalances by the gear system. The support plate and the motor are arranged between the imbalances and the shaft frame.

A method of controlling a massage system for a seat of a vehicle is provided. The system includes a power supply, a drive motor, an operation switch, and a controller. The controller determines whether the driver is drowsy driving based on a parameter and controls an operation of the drive motor through the operation switch. The controller enters a relax mode when the driver is drowsy driving, connecting the power supply to an ON terminal of the operation switch to operate the drive motor at the relax mode.

An exciter apparatus includes an exciter housing and at least one bearing means supporting at least one driven shaft carrying eccentric mass means. The exciter housing includes an array of bore passages extending from an upper wall of the exciter housing to a lower wall of the exciter housing. A mounting structure plate is securable to mineral processing or handling equipment intended to be vibrated by the exciter apparatus. The mounting structure plate has an array of fastener receiving zones, whereby elongated fastener means can pass through the bore passages from the upper wall to be engaged in the fastener receiving zones. The exciter apparatus further includes a pair of bearing members supporting a pair of driven shafts having intermeshing gears. Each of the bearing members and intermeshing gears have individual liquid lubrication sump zones separate from one another, and cooling means for cooling moving parts of the exciter apparatus.
