摘要： A hybrid elastomer-and-metal spring isolator (20) with a low natural frequency. A fully bonded sandwich mount (22) has cored pockets (28) that receive metal coil springs (30). Extruded cavities (32) on the lower (26L) and upper (26U) plates of the sandwich mount (22) extend into the pockets (28) within the interior of the coiled springs (30) and receive a tension bolt (40) and double lock-nut assembly (42) to secure the separate lower cavities to the isolator. A preload retention nut (48) engages a protruding portion of the tension bolt (40) and preloads the coil springs (30) to an amount equal to their static load. This hybrid isolator (20) has particular application in mounting large (30 ton) diesel engines. The isolator assembly provides a natural frequency that is between 3 and 5 Hz, outside the normal idling frequencies of the engine so as to avoid resonance.

摘要： A portable controllable fluid device (20a) for rehabilitation of injured limbs, appendages and joints (33a). The rehabilitation device (20a) includes a first bracket (22a) for fixedly securing to a first body part, such as a lower leg (25), a second bracket (24a) for fixedly securing to a second body part, such as a foot (26), and a controllable fluid brake (27a) such as a magnetorheological fluid brake including a magnetorheological fluid contained therein having a carrier fluid and disbursed magnetic particles, attached between the first bracket (22a) and second bracket (24a). The controllable fluid brake (27a), preferably acts in a rotary fashion and provides resistive forces about an axis adjacent said body joint (33a) to exercise the muscles upon movement of said first bracket (22a) relative to said second bracket (24a) resulting from movement of the user's first body part relative to the second body part. The device (20a) is portable and can be used to rehabilitate, for example, a wrist, elbow, knee or ankle joint in the user's home. The device (20a) allows variable adjustment of the level of resistance felt by the rehabilitating user by adjusting a controller (28a). In another embodiment, feedback information is used to control the level of resistance according to a predetermined force/torque profile(s). A potentiometer (53d) provides the feedback information regarding position to the controller (28a).

摘要： The present invention provides an auxiliary torsional damper (110) of the surface-effect type capable of damping torsional spikes which may occur during operational transition through the system's resonance frequency. Preferably, the auxiliary damper (110) will be designed with a decoupling feature (114) such that the damper (110) will only provide auxiliary torsional damping for torsional oscillations which surpass a threshold amplitude. Since the surface-effect damper of the present invention is deflection dependent, the larger the magnitude of the torsional spike, the larger the damping that will be applied thereto.
摘要翻译：本发明提供一种表面效应型的辅助扭转阻尼器（110），该辅助扭转阻尼器能够抑制在通过系统的共振频率的操作过渡期间可能发生的扭转尖峰。优选地，辅助阻尼器（110）将被设计成具有去耦特征（114），使得阻尼器（110）将仅为超过阈值振幅的扭转振荡提供辅助扭转阻尼。由于本发明的表面效应阻尼器是偏转依赖的，所以扭转尖峰的幅度越大，施加到其上的阻尼就越大。

摘要： An active noise control system (20) which generates via an electronic controller (22) a canceling signal(s) which are responsive to a signal from an error sensor(s) (28) to drive a speaker (30) or array of speakers. Each speaker (30) is contained within an enclosure (33) and is inversely and rigidly mounted therein. The enclosure (33) attaches to the trim panels (25) attached to the closed structure (34) and the canceling sound wave form is directly primarily toward the interior surface (36) of the trim (25).

摘要： The invention relates to a fluid device (20) for providing high load carrying capacity in one direction and which provides a high level of damping along a substantially perpendicular direction. This is achieved by a device which includes an inner member (22) and an outer member (24) and a flexible section (28) causing a connection therebetween, said flexible section (28) exhibiting a substantially higher stiffness along one axis, a fluid cavity (34) formed within said device (20), a piston (38) attached to one of said inner member (22) and said outer member (24), said piston (38) being substantially surrounded by, and submersed in said fluid. In one embodiment, the piston (38) includes a piston area Ap which is substantially greater than 1/2 the fluid cavity area Ac. Movement of the piston (38) within the fluid cavity (34) causes a damping force comprising a throttling component as well as a viscous shear component. Means are disclosed for substantially increasing the viscous shear component and throttling component including novel piston concepts. This invention has particular utility for use in hingeless rotor systems for helicopters.

摘要： A non-active regenerative system (20) which regenerates energy by taking energy from relative motion of members (22) and (24) and using it later to accomplish overall improved performance and eliminates the need for an active source to provide assisting forces. The non-active regenerative system (20) includes an energy transformer element (26) interconnecting a first member (22) and a second member (24) which converts relative motion to an energy in storable form, and an energy management element (30) which channels the flow of energy to and from an energy storage element (32) to produce assisting forces. The energy management element (30) is commanded by a controller (36) which is responsive to sensors (34a, 34b, 34c, and 34d) which provide signals indicative of the system condition. Power is supplied to the energy management (30), sensors (34a, 34b, 34c, and 34d), and controller (36), only if required, by power source (40). However, no active power source is needed to drive the transformer element (26).
