A triple mass flywheel (104, 304, 504, 604) includes a first flywheel part (112, 312, 512, 612), a second flywheel part (114, 314, 514, 614), and a third flywheel part (116, 316, 516, 616) all arranged for rotation on an axis (118, 318). The triple mass flywheel (104, 304, 504, 604) also includes a first torsional damper (120, 320, 520, 620) connected to the first flywheel part (112, 312, 512, 612) and the second flywheel part (114, 314, 514, 614) and a second torsional damper (122, 322, 522, 622) connected to the second flywheel part (114, 314, 514, 614) and the third flywheel part (116, 316, 516, 616). The second flywheel part (114, 314, 514, 614) is driven by an electric motor (110, 310, 510, 610) to adjust the loading of the first torsional damper (120, 320, 520, 620) in relation to the first flywheel part 112, 312, 512, 612) and the second torsional damper (122, 322, 522, 622) in relation to the third flywheel part (116, 316, 516, 616). The electric motor (110, 310, 510, 610) can also be driven by the second flywheel part (114, 314, 514, 614) to store electrical energy for use in a vehicle.

A variable inertia flywheel apparatus includes a cylindrical body member defining a longitudinal axis extending between spaced apart front and rear faces of the body member and an arc-shaped groove portion extending circumferentially relative to the longitudinal axis. The arc-shaped groove portion configured to selectively receive one or more tuning weights having a collective mass sufficient to vary an inertial property of the cylindrical body member between a first inertial property with the tuning weights selectively removed from the arc-shaped groove portion, and a second inertial property greater than the first inertial property with the tuning weights selectively received in the arc-shaped groove portion. A variable inertia flywheel system or assembly includes a tuning weight and a variable inertia flywheel apparatus including a cylindrical body member defining a circumferentially extending arc-shaped groove portion configured to selectively receive the tuning weight to vary the inertial property of the cylindrical body member.

Devices, systems, and methods are provided to treat tremor in a subject. Devices, systems and method may comprise a wearable based configured to be worn over at least a part of a joint of the subject; at least one flywheel-spring-damper system (FSD) comprising at least one housing configured to be coupled to the wearable base; and at least one flywheel configured to counteract tremor movements in the subject, wherein the flywheel-spring damper system is configured to be coupled to the wearable base. The tremor may be a tremor in an outer extremity, typically a hand, of a subject.

A method for storage of excess energy which would otherwise be lost, the regulation of angular velocity, and prevention of excessive velocities is disclosed. The device consists of a bowl shaped container, divided into sections by radially oriented vertical walls, which holds a fluid (any appropriate liquid or set of small solid particles), and spins on its vertically oriented axis at various angular velocities. The floor of the device is formed in successive shapes of bowls and shelves, which allows for a kind of “gearing”. The invention allows more and more energy to be input into the device while the angular velocity is regulated within a particular range. A typical embodiment of the invention would include its attachment by a shaft at the axis to a vertical axis wind turbine.

A variable mass flywheel arrangement comprising a shaft with a flywheel fixedly connected thereto. The flywheel comprises a cavity with at least one inlet thereto. The inlet into the cavity is in fluid communication with a source of particulate matter and the particulate matter is able to pass into the cavity of the flywheel via the inlet.
