20090108510 | Screw type inerter mechanism - A screw type inerter mechanism includes a screw with a limit portion and a thread portion with threads; a screw cap engaged with the thread portion of the screw; an inertia body fixed to the limit portion of the screw; and a connection body engaged with the limit portion of the screw wherein an axial of the screw serves as a rotation axial for the screw to rotate relatively to the connection body. Thus, when a non-zero external force is applied to the inerter mechanism to generate relative horizontal displacement between the screw cap and the connection body, the screw cap brings the screw to rotate, which further brings the inertia body to rotate, thereby achieving the inerter features. | 04-30-2009 |
20090139225 | HYDRAULIC INERTER MECHANISM - The invention provides a hydraulic inerter mechanism, including: a hydraulic cylinder; a hydraulic motor connected to the hydraulic cylinder, with an output shaft thereon for converting the motion of the hydraulic cylinder from rectilinear motion to rotary motion; and an inertia body disposed on the output shaft. In operation, an external force applied to the inerter mechanism causes displacement of the piston, thereby pushing working fluid inside the hydraulic cylinder to generate a pressure difference between an inlet and an outlet of a hydraulic motor. The differential pressure consequently drives the hydraulic motor to rotate, and then the output shaft further drives the inertia body to rotate, thereby attaining inerter characteristics. | 06-04-2009 |
20090176133 | FUEL CELL CONTROL SYSTEM AND CONTROL METHOD THEREOF - A fuel cell control system and a control method thereof are provided. The fuel cell control system includes an air supply module, a fuel supply module having a fuel supply end, a fuel cell set having an electrical output end, an measuring unit and a control module having an arithmetic logic unit. A set of control algorithms is employed to effectively adjust the electrical output in order to identify the transfer function and to perform controller design. When the electrical output of the fuel cell is different from the default electrical output, the controller then regulates the fuel supply and the air supply to provide a stable fuel cell electrical output and to reduce fuel consumption. | 07-09-2009 |

20100148463 | Mechatronic suspension system and method for shock absorbing thereof - The invention provides a mechatronic suspension system and a method for shock absorbing thereof. The invention applies the analogies between mechanical and electronic networks to propose a mechatronic suspension system, which combines a ball-screw inerter and a permanent magnet electric machinery, such that the complicated network structure can be realized through the combination of mechanical and electronic networks. The mechatronic suspension system is connected to two terminals, and consists of the inerter mechanism, the permanent magnet electric machinery and the feedback circuit. The inerter mechanism is connected to the terminals to transfer the linear motion into the rotational motion. The permanent magnet electric machinery is connected to the inerter mechanism to generate a corresponding voltage. And the feedback circuit is connected to the permanent magnet electric machinery to provide suitable system impedance and to generate a feedback force. | 06-17-2010 |
