A cooling system includes a coolant source to cool down components of a processing chamber and a return line for the coolant coupled between the processing chamber and the coolant source. The return line has a valve, which includes a flow compartment having a first inlet and an outlet that support a default flow rate of the coolant, the flow compartment also having a second inlet. The valve has a plunger with a tip to variably open and close the second inlet to vary a flow rate of the coolant from the default flow rate. The valve has a shape memory alloy (SMA) spring positioned on the plunger between a side of the valve and the tip, the SMA spring attached to the tip to variably withdraw the tip from the second inlet in response to a rise in temperature of the coolant above a threshold temperature value.

A valve includes a first inline compartment to attach to a first return line exiting a processing chamber and a second inline compartment to attach to a second return line entering a coolant source. A flow compartment is attached between the first inline compartment and the second inline compartment and through which a coolant is to return to the coolant source. A first inlet orifice and a second inlet orifice positioned between the first inline compartment and the flow compartment. A plunger has a tip to variably open and close the second inlet orifice. A shape memory alloy (SMA) spring is positioned on the plunger and attached to the tip, the SMA spring to variably increase or decrease a flow rate of the coolant through the second inlet orifice according to a temperature of the coolant.

A vibration isolator can be configured to provide improved vibration isolation performance, such as in connection with a bicycle saddle. A vibration isolator can be operatively connected to a bicycle saddle. The vibration isolator can be configured to exhibit a non-linear stiffness profile. The non-linear stiffness profile can include a region of quasi-zero stiffness. The vibration isolator can include one or more movable body members and one or more super elastic material members.

A suspension assembly is described. The suspension assembly including a static member or plate; a moving member or plate movable about an x-axis and a y-axis with respect to the static plate; a sensor mounting region on the moving plate; and one or more shape memory alloy (SMA) elements extending between and coupled to the static plate and moving plate. The SMA elements, when driven by a controller, move the moving plate and the sensor mounting region thereon about the x-axis and the y-axis with respect to the static plate.

A damper is disposed in a holding hole that passes through, in a passing-through direction, a supported member that is supported by a supporting member. The dumper includes a tubular body defining therein a through hole extending in the passing-through direction. The tubular body is elastically deformable between a first form and a second form. The tubular body in the first form has an outer shape that is smaller than the holding hole. The tubular body in the second form has an outer shape that is equal to or greater than the holding hole.

An epicyclic gearbox is configured to transfer rotational motion between a first rotating component and a second rotating component of the gas turbine engine. The gearbox includes a centrally located sun gear, two or more planet gears circumscribing the sun gear, and a ring gear circumscribing the plurality of planet gears. The gearbox is configured such that the sun gear is drivingly coupled to the first rotating component, such that rotation of the sun gear causes rotation of each planet gear, and such that the ring gear rotates relative to the plurality of planet gears. The gearbox includes one or more shape memory alloy dampers provided in association with the sun gear, the ring gear, and/or the plurality of planet gears. The shape memory alloy damper(s) is configured in order to reduce vibrations transferred through the epicyclic gearbox to the frame, the first rotating component, and/or the second rotating component.

A transducer system isolates vibrations produced by a transducer. The transducer system comprises the transducer and a vibration isolation system. The transducer can produce vibrations and is configured to be coupled to a device. The transducer includes a first sub-assembly including a coil assembly and a second sub-assembly including one or more magnets. The vibration isolation system is configured to isolate vibrations produced by the transducer from the device. The vibration isolation system includes a plurality of support brackets, and a suspension component including a plurality of flexures. The plurality of flexures includes a first set of flexures configured to suspend the first sub-assembly from the support brackets, a second set of flexures configured to suspend the second sub-assembly from the first sub-assembly, and a third set of flexures configured to suspend the second sub-assembly from the support brackets.

A multi-flexure payload isolation device for isolating a payload from outside forces. The device can include a housing comprising an interior cavity configured to receive and support the payload. The device can further include a first flexure and a second flexure, each including a plurality of spokes made of a pseudoelastic shape-memory alloy anchored to the housing and configured to support the payload from the housing through an opening in the housing. The first and second flexures can each further include a common hub attached to a side of the payload and disposed in the opening in the housing wherein the each of the pluralities of spokes are anchored to the respective common hub.

A magnetostriction-based vibration suppression apparatus for a steel pipe of a power transmission tower includes a lantern ring, four spoiler cups, and two control boxes; the lantern ring is fixedly sleeved on the steel pipe; mouths of the spoiler cups face outwards, and bottoms thereof are hinged on the lantern ring; the four spoiler cups are squarely distributed; and the two control boxes are symmetrically and fixedly mounted on the lantern ring; the control boxes are arranged as follows: the spoiler cups are arranged in pairs as a group, and each control box is arranged between two spoiler cups; each control box is provided therein with two groups of inerter units corresponding one-to-one to the spoiler cups. The vortex is avoided using a structure such as a spoiler cup, and the vibration kinetic energy of the steel pipe is consumed, thereby achieving an effective vibration reduction effect.

A damping mechanism for damping energy resulting from a lateral force on a structure may include a first portion, a second portion configured for longitudinal motion relative to the first portion, a primary energy absorption system configured for frictionally coupling the first portion and the second portion and converting motion of the second portion relative to the first portion into heat energy, and a secondary energy absorption system configured to absorb energy through non-linear deformation and provide a self-centering effect on the damping mechanism.
