摘要： A method and apparatus is disclosed in which a piezoelectric film is used to control or dampen vibrations in a mechanical system. Voltage of proper amplitude and phase is fed across the piezoelectric film to induce strain in the film of appropriate phase, amplitude and frequency to dampen beam vibrations of the mechanical system. The film may be applied directly to the mechanical system or an intermediate viscoelastic layer may be provided. Various control functions are described for determining the correct voltage to be applied to the film.

摘要： As mobile computing devices are increasingly expected to be smaller, thinner, and/or lighter, less space is available for incorporating such structurally stiff perimeter components, as well as energy-absorbing components. The electroactive perimeter stiffening devices, systems, and methods described herein detect a free-fall event or condition, anticipate a subsequent impact event, and actively stiffen one or more electroactive perimeter stiffeners of an associated mobile computing device in preparation for the impact event. The electroactive perimeter stiffeners direct impact energy away from, and in some cases, distribute and/or dissipate the impact energy, in an effort to prevent damage to impact-sensitive components of the mobile computing device.

摘要： A damper includes a cylinder that seals a magneto-rheological fluid, a piston slidably disposed in the cylinder, and a piston rod coupled to the piston. The piston includes a piston core, a flux ring, a plate, and a fixing nut. The piston core is mounted on the piston rod. The piston core has an outer periphery on which a coil is disposed. The flux ring forms a flow passage for the magneto-rheological fluid with the piston core. The plate is disposed on an outer periphery of the piston rod, has an outer peripheral surface housed in a one-end of the flux ring, and is bonded on the flux ring by brazing. The fixing nut sandwiches the plate with the piston core.

摘要： A vibration dampening device is operable to dampen vibrations within ropes of an elevator car or other components to improve ride quality, and is further operable to harness or harvest and convert energy from those vibrations into electrical energy. The dampening device includes a macro-fiber composite and the vibrations are communicated or transmitted to the macro-fiber composite. The macro-fiber composite is operable to harness or harvest and convert energy from vibrations into electrical energy. Such electrical energy is communicated or transmitted to a control system of the elevator car for storage and/or use.

摘要： A shock absorber includes a pressure tube forming a working chamber. A reserve tube is concentric with and radially outward from the pressure tube. A baffle tube is positioned radially outward from the pressure tube. A reservoir chamber is formed between the reserve tube and the baffle tube. A piston is attached to a piston rod and slidably disposed within the pressure tube. A rod guide is attached to the pressure tube and supports the piston rod. An electromechanical valve is positioned within the rod guide. The baffle tube and the pressure tube form a fluid passage between the electromechanical valve and the reservoir chamber.

摘要： Disclosed herein is an adaptive system that converts vibration in mechanical structures into electrical energy using a transducer having piezoelectric properties. The electrical energy generated is then converted into heat loss in an electrical circuit comprising: an adaptive inductance that autonomously changes its value by comparing the phase difference of the vibration velocity and the current flowing through the shunt circuit; a resistance to convert electrical energy into heat loss; and a synthetic negative capacitance to enhance the vibration attenuation.
