A haptic actuator may include first and second bodies movable along an arcuate path of travel. The haptic actuator may also include a biasing member coupled between the first and second bodies. At least one electrical coil may be configured to move the first and second bodies to produce a haptic effect.

A system and method for calibrating and controlling an active dampening system for a chassis of a vehicle having an engine involve operating the engine in a cylinder deactivation mode and, during the cylinder deactivation mode, (i) receiving, from a set of sensors, measured vibrations on first and second frame rails of the chassis, (ii) generating control signals for a set of actuators based on the measured vibration of the first and second frame rails, each actuator being configured to generate a vibrational force in at least one direction, and (iii) outputting, to the set of actuators, the control signals, wherein receipt of the control signals cause the set of actuators to generate vibrational forces that dampen the vibration of the first and second frame rails, respectively, to decrease noise/vibration/harshness (NVH).

The invention refers to an infrasound generator for enhancing the combustion of solid fuels burning in a combustion chamber. The infrasound is generated by one or more set(-s) of each two vibrating plates, vibrating in the same direction with the same displacement amplitude but in antiphase. The infrasound generator does not cause vibrations and is not sensitive to ash and heat from the combustion.

[Object] To provide a technology capable of causing, by controlling the direction in which a housing is to be vibrated, a user to easily recognize that the housing is vibrating.

[Solving Means] An information processing apparatus according to the present technology includes a housing; a sensor; a vibration unit; and a control unit. The housing has a first direction, and a second direction different from the first direction. The sensor is provided in the housing. The vibration unit is capable of vibrating the housing in the first direction and the second direction. The control unit determines a current situation of the housing on a basis of output from the sensor, and controls, on a basis of the current situation of the housing, the vibration unit to vibrate the housing in one of the first direction and the second direction.

A vibration wave motor includes a vibrator, a pressing member configured to press the vibrator against a friction member, a holding member configured to hold the vibrator, and a buffering member provided between the vibrator and the holding member. The vibrator and the friction member are moved relatively to each other in a relative movement direction by vibration of the vibrator, and the holding member holds the vibrator in such a manner that an extending part extending in a pressing direction of the pressing member sandwiches the vibrator and the buffering member.

A haptic actuator includes mechanical links defining a first J-trajectory and mechanical links defining a second J-trajectory as well as a motor coupled to the mechanical links so as to synchronously accelerate a first mass over the first J-trajectory and a second mass over the second J-trajectory. During a first time interval, reactive forces of the first mass accelerating substantially balance reactive forces of the second mass accelerating and during a second time interval reactive forces of the first mass accelerating do not substantially balance reactive forces of the second mass accelerating. This un-balanced condition results in a tap signal being produced.
