A game controller including a housing with a first handgrip and a second handgrip is provided. The game controller includes a first vibration actuator integrated within the housing proximate to the first handgrip. Further included is a second vibration actuator integrated within the housing proximate to the second handgrip. A controller device is included and is configured to communicate one or more vibrational signals to one or both of the first vibration actuator and the second vibration actuator. The vibrational signals are configured to cause the housing of the game controller to vibrate in a vibrational pattern during use of the controller. The vibrational pattern is one of a plurality of vibrational patterns, and one or more of the plurality of vibration patterns are activated in correlation to one or more game actions occurring during gameplay of a video game using the game controller.

Aspects of the technology employ components to control and combine the vibration outputs of two vibration motors into essentially a pure vibration force, which can be controlled to output a given frequency and amplitude, produce beat frequencies, and produce brief impulses. For instance, identical attachment elements are affixed to a vibration device but do not contact each other during operation. Such attachment elements are able to cancel undesired torque vibrations to provide a combined pure force vibration output. The attachment elements may be secondary eccentric rotating masses affixed to the shaft of a vibration motor. Along with the vibration motor's primary eccentric rotating mass, these elements can cancel out unwanted parasitic torque vibrations by producing counter-torque vibrations.

Circular force generator devices (100), systems, and methods for damping vibrations which include two complementary rotor assemblies (110, 120) that are rotatable together about a common shaft (102) but that have an adjustable rotational position (P1, P2) with respect to one another such that a significant reduction in rotor inertia and bearing drag relative to conventional CFG configurations is provided. The present architecture creates virtually zero rotating moment.

The present invention generally relates to a vibrator for generating vibrations. The invention is in this respect in particular based on an exciter cell having rotationally drivable unbalanced masses that are rotatably supported in an exciter cell housing and having an adjustment unit for adjusting the phase position of the unbalanced masses relative to one another. In accordance with the invention, the adjustment unit is configured as a planetary gearing that has at least two input trains to which the unbalanced masses of the exciter cell are coupled that are adjustable in phase relative to one another and that has an adjustment input train for changing the phase position of the output trains of the planetary gearing.

The invention relates to a vibration generator for piling machines, compactors or other construction machines, having at least two unbalance trains, each comprising unbalanced masses which are rotatingly drivable by a drive apparatus, and an adjustment apparatus for adjusting the phase position of the rotating unbalanced masses relative to each other. According to the invention, the unbalanced masses of different unbalance trains are arranged coaxially without a fixed transmission ratio relative to each other, wherein the unbalanced masses of a first unbalance train are arranged between the unbalanced masses, coaxial therewith, of a second unbalance train, and the drive apparatus is designed to drive the unbalance trains with rotation speed differences which are variable relative to each other.

An oscillation module for a compacting roller of a soil compactor includes a plate-like carrier, at least two oscillation mass units supported on the carrier at a distance from one another, and an oscillation drive motor supported on the carrier. The carrier has a connection formation for firmly connecting the carrier to a carrier structure of a compacting roller. Each oscillation mass unit includes an imbalance mass rotatably supported on the carrier about an oscillation axis of rotation. Each imbalance mass of each oscillation mass unit can be driven by the oscillation drive motor for rotation about the respectively assigned oscillation axis of rotation.

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.
