The disclosure relates to integrated modules for Synchronized Array of Vibration Actuators (FIG. 125A). The modules provide physical interface, power and communication interfaces. Each module may include vibration actuators (FIG. 123A) which can be precisely attached and aligned to the module housing, a microcontroller or other microprocessor, and one or more sensors for closed loop control of actuators (FIG. 126G). Interleaved pairs of ERMs having a center of mass in the same plane eliminate parasitic torque. A single module can produce a vibration force that rotates at a specific frequency and magnitude, which on its own could cancel out some types of periodic vibrations (FIG. 125B). Two modules paired together and counter-rotating with respect to each other can produce a directional vibration at a specific frequency and magnitude, which could prove even more useful for canceling out a vibration. Such modules are also employed to produce beating patterns (FIGS. 131-133). Both amplitude and frequency of the beating force are variable.

The automated wind chime comprises a housing and a wobble arm. The housing may be suspended from a clapper of a wind chime. A motor within the housing may rotate the wobble arm when energized. The wobble arm may be unbalanced such that rotation of the wobble arm causes the housing to sway in an erratic pattern. Moving the housing in the erratic pattern may cause the clapper to strike a plurality of percussion targets within the wind chime thus producing chime music even in the absence of wind. The housing may have a novelty appearance. As non-limiting examples, the housing may be shaped like a duck, turkey, Easter bunny, Santa Claus, musical note, or flower.

A vibration attenuator for a rotor of an aircraft has a housing adapted for rotation with the rotor about an axis. A first ring is rotatably carried within the housing on a first bearing, a first weight being coupled to the first ring for rotation therewith relative to the housing about the axis. A second ring is rotatably carried by the first ring on a second bearing, a second weight being coupled to the second ring for rotation therewith relative to the housing and to the first ring. A first motor is configured for rotating the first ring relative to the housing, and a second motor is configured for rotating the second ring relative to the housing and to the first ring. The first and second motors are operated to rotate the weights within the housing and position the weights relative to each other for attenuating vibrations.

A mechanism with a base; a pendulum mounted pivotally relative to the base about a pendulum axis; first/second eccentric elements generating first/second moments of gravitational force about first/second axes; and a synchronization system of the first/second eccentric elements according to a synchronized counter-rotating rotational movement. The pendulum axis and eccentric elements' axes are parallel and arranged in the plane integral to the pendulum. The eccentric elements' axes are supported by the pendulum, above and below the pendulum axis. The eccentric elements are movable in synchronized counter-rotating rotation, with cross-centrifugations, the pendulum pivots alternately on one side then the other, amplifying the rotational movement of the eccentric elements, by simultaneous cross-thrusts of the pendulum against the eccentric elements' axes, and by the transmission of torque to the synchronization system, and the energy generated by centrifugation within the mechanism is recoverable by coupling an energy recovery system to the synchronization system.

Provided is a concrete vibrator capable of automatically changing the rotational speed of a motor depending on the state of a vibrating tube and suitably avoiding overheating of the motor and a failure due to the motor overheating.

Under control of control means 8, the concrete vibrator is operated in a normal mode in which a motor 2 is supplied with driving power having a frequency that can make the motor 2 rotate at a rotational speed suitable for an air bubble removing process, or in an idling mode in which the motor 2 is supplied with driving power having a frequency that can make the motor 2 rotate at a rotational speed lower than the rotational speed in the normal mode. The control means 8 measures, per unit of time, a value of a current that is input to the control means 8 or the motor 2 to record the value in a memory, compares a latest current value to a reference value calculated on the basis of a past measurement value, and further compares an absolute value of the comparison value to a threshold to grasp the state of the vibrating tube so that an operation mode is suitably switched.

The present invention is a controller with a motor module. The controller with a motor module comprises a body. A support is disposed inside the body. The support comprises an alignment part and an engaging part both are disposed on the support. A motor module has a central axis and is capable of dismounting from the support. The motor module comprises a housing, a matching part and a blocking part both are disposed on the housing. When the motor module is applied a force to make the motor module rotates along the central axis thereof, the matching part engages with the alignment part, and the blocking part engages with the engaging part.

A rocking device provided with a fastening means (9) for mounting to for example a baby buggy to create an automatic rocking movement of the baby buggy. It comprises a rotating, asymmetrical weight (14) driven by an electric moto (24). The motor and weight are suspended in a rigid fastening bracket. The fastening bracket (13) is fastened to a first side of a vibration dampening connection element (3) of an at least partly soft material. The fastening means is fastened to the other side of the vibration dampening connection element (3), such that the movement of the weight is transmitted through the fastening bracket (13), via the vibration dampening connection element (3) and the fastening device, to the baby buggy. The fastening bracket with motor a weight is enclosed by an outer cover (1, 2) which is not in contact with the fastening bracket, motor or weight. The outer cover is fastened to the vibration dampening connection element (3), such that vibrations from the motor and the weight are not transmitted to the outer cover.
