A device for spreading fowl decoys on the surface of a body of water. A hub sits below the surface is removably coupleable with up to four arm arrangements. Arm arrangements are jointed, allowing hub and arm arrangements to sit below the surface of the water while decoys float on surface. Hub is connected to an anchor on the bottom of the body of water, and can be displaced horizontally with a pull cord. Cords in the arm arrangements allow for near-random motion of attached decoys, simulating a swimming motion of fowl. Hub can be displaced vertically with a pull cord, causing the decoys to dip head first into the water, simulating a feeding motion of water fowl. Hubs can be combined by coupling arm arrangements from each hub. When displaced horizontally in the water, hubs not attached to the pull cord move semi-randomly, creating more random motion in decoys.

A vehicle active damper includes a damping actuator that is provided between a radiator and a vehicle body so as to be interposed in a substantially vertical direction, and a coupling member that elastically couples between the vehicle body and an engine. The damping actuator is formed from a elastic modulus-variable member having an elastic modulus that varies according to the strength of an applied magnetic field. The coupling member transmits vibrations of the engine to the vehicle body along a substantially vertical direction.

A robot shares a work space with a person, to perform an operation. The robot includes a shock-absorbing member which covers the periphery of at least a base part of a working tool attached to an robot arm, a detector which is provided for the robot arm, to detect an external force input via the shock-absorbing member, and a robot control device which stops the robot when determining, based on information of the detected external force, that the working tool collides with the person. The external force is transmitted from the working tool to the robot arm, and is detected by the detector.

A vehicle powertrain proactive damping system includes a plurality of proactive damping structures mounted on a powertrain structure with each proactive damping structure includes a magneto rheological elastomer (MRE). An electromagnet is associated with each proactive damping structure. A control unit includes a processor circuit. A sensor obtains vibration data regarding the powertrain structure. A LIDAR sensor is mounted on the vehicle and is electrically connected with the control unit. The LIDAR sensor provides data to the control unit indicative of upcoming road surface conditions to be experienced by the vehicle. Based on data from at the sensor and the LIDAR sensor, the processor circuit is constructed and arranged to control voltage to the electromagnets to selectively adjust a rigidity of the associated proactive damping structure so as to control vibrational effects on the powertrain structure.

A parallelogram suspension in a bicycle, the parallelogram suspension comprising a first swing arm rotatably coupled to a seat post at a first end of the first swing arm; a second swing arm rotatably coupled to the seat post at a first end of the second swing arm; a linkage rotatably coupled between a second end of the first swing arm and a second end of the second swing arm; a deformable support disposed in a volume defined between the first swing arm, the second swing arm, and the linkage; and a release configured to selectively open the volume to release the deformable support.

A bracket-equipped vibration-damping device including: a vibration-damping device main body including vertically-separated, elastically-connected first and second mounting members; a bracket receiving the device main body inserted laterally thereinto; a connection-insert section provided for the second mounting member; a connection groove provided for the bracket extending in an insertion direction of the device main body; at least one up-down urging rubber fixed on an outer surface of the connection-insert section on an upper-lower first side; and a lock protrusion formed on an inner surface of the connection groove on an upper-lower second side, with a smaller protrusion dimension than an up-down thickness of the up-down urging rubber such that the connection-insert section is laterally inserted into the connection groove beyond the lock protrusion before being urged to the second side by the up-down urging rubber to be positioned to the connection groove.

A dispensing pump (1000) includes a polymer compression spring (1048), base vents (1060) and a flow baffle (1092). The dispensing pump includes a pump base (1002), and a dispensing head (1004) having a piston stem (1034). The polymer compression spring assembly includes a slotted tubular spring element (1048) and first and second loading cones received at opposing ends of the slotted tubular spring element. The venting ports allow air to escape when capping the container after filling and the flow baffle reduces or prevents the product from being pulled into the pump accumulator before residual air (headspace) has been evacuated from the container during the initial priming strokes.
