A self-excited wind power system with at least one self-excited panel, each arranged to create periodic motion in response to wind velocity, and a support tower. The self-excited panel is segmented, with at least three segments: a first segment forming a master segment, a second segment, and a third segment defining a tail segment. The first segment of the self-excited panel has a first length and a first height, the second segment has a second length half the length of the first segment and a second height one-third the height of the first segment, and the third segment has a third length half the length of the first segment and a third height one-third the height of the first segment. Furthermore, the second and third segments are connected to the proximal and distal ends of the first segment via a bearing mechanism.

A vehicle safety device for reducing whiplash in a vehicle includes a curved guide configured to allow a seat to slide thereon, an impact sensor that can detect an impact on a rear end of the vehicle; and a locking mechanism that can allow the seat to slide on the curved guide when an impact is detected by the impact sensor. The locking mechanism can prevent the seat from moving relative to the curved guide when there is no impact detected by the impact sensor.

The proposed invention is an indoor firefighting robot which has the capability to climb stairs and negotiate several types of floor materials inside buildings. it can withstand very high temperature up to 700 Celsius for as long as 60 minutes using multiple thermal insulation technique. It can communicate with trapped and injured persons inside the fire scene and can send back video and audio information describing the fire environment inside the building to the controller. It has also an insulated container at the rear with oxygen masks to help victims to breathe safely in the smoke environment in the early stage of the firefighting process. Several of these compact firefighting robots can be launched and can work together inside the room or multiple rooms under fire with assistance of remote control unit. The fire robot can avoid obstacles while trying to rescue injured victims.

An isolation base system for sensitive structures such as nuclear power plant modules is suggested. The proposed isolation system considers a base supported on specially designed hollow spherical balls and equipped with 3 linear hydraulic actuators to restrict the lateral motion of the base and provide a stable base under normal conditions. The actuators are released when an earthquake signal is detected to allow the base to oscillate freely during the earthquake attack. The hydraulic actuators are reactivated after shock wave ends to compress the springs and restore the base to its original position.
