    摘要: A method for using a special class of low-harmonic Bezier curves to plan and generate trajectory patterns for computer-controlled machinery in which desired motion information is input into a first processor. A low-harmonic trajectory is then generated from the desired motion information according to the low-harmonic Bezier curves and output into a second processor where points along the low-harmonic trajectory are computed. Each point on the trajectory is then output, amplified, and input into an actuator for performing a desired motion, but which results in an actual motion. The actual motion is then compared to the desired motion in a comparing means which computes an error. A feedback control signal is then generated to correct the error. Lastly, the method is repeated for all points on the trajectory until the trajectory is complete or the operation is terminated. Another aspect of the present invention is an apparatus for carrying out the method of the present invention.

    摘要: A walkway for use between a shoreline of a body of water and at least a portion of a building exposed to the body of water, the walkway including: a base adjacent to the building; a plank having a surface for use by pedestrians to walk upon when the plank is in a first position at least indirectly disposed on the base, the plank having a first end rotatably connected to the base and having a second end extending from the first end away from the building along a length of the plank, the surface being exposed for use by the pedestrians to walk upon when the plank is in the first position; and a lifting mechanism operatively connected to the plank to rotate the plank from the first position to a second position where the length of the plank is oriented adjacent to a wall of the building to impede a rising height of the body of water.

    摘要: A method for generating power in a gravity dropped munition, the method including: winding a cable around a drum of a generator associated with the munition; attaching the cable from the generator to a portion of an aircraft; separating the munition from the aircraft to unwind the cable from the drum to release the cable from the drum after a predetermined amount of rotation of the drum; converting the rotation of the drum to energy in a spring as the cable is unwound from the drum; restricting movement of an intermediate member connecting the drum to the generator while the cable is being unwound from the drum; and ending the restricting when the cable is released from the drum allowing the intermediate member to engage the drum with the generator to produce power from the generator.

    摘要: A method for generating electrical power, the method including: storing potential energy in an elastic element having one end attached to a shaft and another end attached to a structure upon rotation of the shaft relative to the structure in a first angular direction; and moving a retaining mechanism between an engaged position for retaining the shaft from rotating in a second angular direction opposite to the first angular direction and a power generating position permitting the shaft to rotate in the second angular direction; wherein when the retaining mechanism is moved to the power generating position, the stored potential energy in the elastic element is converted to kinetic energy to rotate the shaft which in turn rotates a generator operatively coupled to the shaft so as to produce electrical power.

    摘要: A power source for generating electrical power. The power source including: a shaft rotatably disposed relative to a structure; an elastic element having one end attached to the shaft and another end attached to the structure for storing potential energy upon rotation of the shaft in a first angular direction; a generator operatively coupled relative to the shaft; and a retaining mechanism movable between an engaged position for retaining the shaft from rotating in a second angular direction opposite to the first angular direction and a power generating position permitting the shaft to rotate in the second angular direction. Wherein, when the retaining mechanism is moved to the power generating position, the stored potential energy in the elastic element is converted to kinetic energy to rotate the shaft which in turn rotates the generator coupled to the shaft so as to produce electrical power.
