Abstract: A support structure for a drive source such as a motor of the blower is disclosed in which the generation of noise caused by the vibration of the motor is suppressed. The flange of a support member has a low-stiffness portion having a thickness smaller than a high-stiffness portion of the same flange. The low-stiffness portion is thus vibrated more easily than the high-stiffness portion. When the motor vibrates, therefore, the vibration rate of the low-stiffness portion increases beyond that of the high-stiffness portion, so that the low-stiffness portion vibrates considerably. The motor vibration is thus absorbed by the flange (support member) and the transmission of the motor vibration to a casing can be suppressed. As a result, the area of the sound source of the blower is decreased as a whole, thereby making it possible to suppress the generation of noise caused by the vibration of the motor.

Abstract: An active vibration control system for controlling excessive or unwanted vibrations in floors or other structures. The system has three main components: (1) velocity sensor w/signal conditioner; (2) feedback controller; and (3) proof-mass actuator. This system works by creating a feedback loop that generates a control force proportional to the velocity, thus adding damping to the controlled modes of floor vibration. In other words, the feedback loop makes the moving mass of the actuator move to counteract the motion of the floor. The system is optimized such that the motor can be driven with a sinusoidal force where the peak force is at or near the full motor capacity at any frequency without exceeding the stroke while maintaining a simple and cost effective feedback controller. Additionally, a relationship between the fundamental natural frequency of the floor system and actuator is established to provide efficient and stable control.

Abstract: Shock and vibration eliminating elements are constructed of an elastomeric material, which is formed into shapes that have an elongated, generally trapezoidal cross-sectional area. Upper and lower mounting surfaces extend from the ends of the cross-sectional area. The upper and lower end mounting surfaces of the damping elements have integral, parallel surfaces that are used to mount the element to the two structures. The cross-sectional area of the damping elements locates the mounting surfaces so that a straight line normal to one of parallel mounting surfaces at one end of the cross-sectional area of a block, will not intersect the other mounting surface at the other end of the cross-sectional area. Thus, a force applied in a normal direction to one of the mounting surfaces will be translated into shear forces instead of comprehensive forces.

Both the data map storage media are added to the active control apparatus of the mass-produced vehicle M. Using both the data maps, it is possible to appropriately and actively control the vibration of the mass-produced vehicle without variation.

Abstract: A seat suspension method in one approach involves applying a dampening force over less than the full range over which a seat may be raised and lowered by a seat height adjuster. The step of applying a dampening force may comprise applying such a force which varies non-linearly, depending upon the extent a seat moves as a result of seat vibration. In several specific approaches, unlatching of the dampening mechanism may be accomplished to permit relative movement of the seat and seat support mechanism during seat height adjustment. Relatching of the vibration damper may be accomplished to again apply a dampening force. The seat may automatically be returned toward a desired elevation in the event loading on the seat is varied, for example if a seat occupant leaves the seat.

Abstract: A highly damped kinematic coupling for precision instruments. The kinematic coupling provides support while causing essentially no influence to its nature shape, with such influences coming, for example, from manufacturing tolerances, temperature changes, or ground motion. The coupling uses three ball-cone constraints, each combined with a released flexural degree of freedom. This arrangement enables a gain of higher load capacity and stiffness, but can also significantly reduce the friction level in proportion to the ball radius divided by the distance between the ball and the hinge axis. The blade flexures reduces somewhat the stiffness of the coupling and provides an ideal location to apply constrained-layer damping which is accomplished by attaching a viscoelastic layer and a constraining layer on opposite sides of each of the blade flexures.
