An apparatus including a plurality of robot arm links movably connected to one another, where a first one of the robot arm links includes a frame, where the frame has a first end movably connected onto a second one of the robot arm links; and at least one vibration damper arrangement on the frame of the first robot arm link, where the at least one vibration damper arrangement includes at least one viscoelastic element connected to the frame of the first robot arm link by a connection such that, as the frame of the first robot arm link experiences vibrations, the at least one viscoelastic element dampens the vibrations in the frame of the first robot arm link based upon viscoelasticity and the connection of the at least one viscoelastic element to the frame of the first robot arm link.

A case includes a base and a cover and defines an accommodation space therein. The base has a first through hole through which a magnetoelectric conversion element, which is mounted on a circuit board, is opposed to a sensor magnet of a motor. A connector includes a terminal and a housing, which supports the terminal. The connector has a first protrusion projected toward the base for positioning. The first protrusion of the connector has a tip end inserted through a second through hole of the printed circuit board and further inserted in a hole portion of the base. A second protrusion of the base is projected toward the printed circuit board and is inserted in a third through hole of the printed circuit board for positioning.

A motor vehicle transmission assembly is provided that includes a dampening component configured to reduce at least one of noise and vibration within the transmission assembly. In some versions, the dampening component is disposed between first and second transmission components, and the dampening component may be fixed to and/or abutting one of the transmission components. The dampening component may comprise a dampening layer disposed between a pair of outer layers. In some versions, the dampening component has a metallic portion and a non-metallic portion.

A printed circuit board and multiple components, which are mounted on both sides of the printed circuit board, form a circuit to drive a motor. The printed circuit board is opposed to a case at a one side. First thermal conductive portion is interposed between a heat generating component of the components and the case. Second thermal conductive portion is interposed between the circuit board and the case. The first and second thermal conductive portions are formed of the same flexible material, are equipped to the same side of the circuit board, are in contact with both the circuit board and the case, and are located at different positions.

Motion-damping systems and methods that include motion-damping systems are disclosed herein. The motion-damping systems are configured to damp relative motion between a base structure and an attached component that define a gap therebetween. The systems include an at least substantially rigid tubular structure that defines an internal volume and extends within the gap. The systems also include a magnetic assembly and a magnetically active body. One of the magnetic assembly and the magnetically active body is located within the tubular structure and the other of the magnetic assembly and the magnetically active body is operatively attached to a selected one of the base structure and the attached component. The magnetic assembly is in magnetic communication with the magnetically active body such that a magnetic interaction therebetween resists motion of the attached component relative to the base structure. The methods include dissipating energy with the motion-damping system.

A composition comprising a liquid-castable polymer system combined with solid particles of a shear thickening additive; an energy absorbing material formed from the composition; and an article comprising the energy absorbing material on a substrate, for example, a glove (1) including the material of the present disclosure as energy absorbing elements (2a, 2b, 2c, 3a, 3b, 3c, 3d, 3e) incorporated onto the surface (4) of a textile substrate to provide protection over the metacarpophalangeal and proximal interphalangeal joints.

A bottom dampener can be provided for a can rack system. The bottom dampener can dampen forces exerted on a bottom of the can rack system by cans inserted into the can rack system. The bottom dampener can include a curved pad, which can fit into a bottom flap of the can rack system. The curved pad can be used for dampening a force exerted by a can on the bottom flap. The bottom dampener can also include one or more tabs. Each of the tabs can fit into a hole along the bottom flap to removably couple the bottom dampener to the can rack system.

Vibration damping viscoelastic damping material laminates are described. The tapes generally include at least two viscoelastic damping material layers and at least one substrate. The tapes may optionally include one or more release liners. Also described are constrained layer systems formed by adhering the tape to a first substrate and/or second substrate undergoing vibration.
