Abstract: A spinning arm that converts a rotational motion of a shaft to a linear movement of an object that includes a revolving piece and a rod. The lower end of the rod is connected to the shaft and the upper end is axially connected to the revolving piece in a state of tilting aside in relation to the rod so that the revolving axis line of the revolving piece crosses the rotation axis line of the rod. The revolving piece can move outwards and roll over the object when its tilt is from right to left. When the revolving piece rolls over the object in a first direction it exerts an upward force that moves the object upward, and when it rolls in a second direction it exerts a downward force that moves the object downward.

Abstract: A harvesting system that includes a dynamo with a rotor and a stator, a push magnet that is attached to the rotor or is a part of it, a moving magnet that moves from a first position to a second position, and a push back magnet. The repulsive magnetic force that is exerted by the moving magnet on the push magnet in the second position is greater than that force in the first position. The moving magnet moves from the first position to the second position and causes the rotor to rotate from a dynamo first position to a dynamo second position that causes the dynamo to produce current. When the moving magnet moves back to the first position the dynamo returns to its first position due to magnetic force that the push back magnet exerts on the push magnet.

Abstract: An electromagnetic energy harvesting system for converting kinetic excitations of a body to electricity. The system includes a coil, a magnet, and a push-back magnet that is fixed to the body. The magnet is connected to the body by an axial connection that enables the magnet to rotate about the axis of rotation that is distal from the center of gravity of the magnet. The push-back magnet exerts repulsive force on the magnet rotates the magnet about its axis of rotation in a way that the center of gravity of the magnet rotates away from the push-back magnet. The kinetic excitations of the body cause the magnet to rotate about its axis of rotation in a way that the center of gravity of the magnet rotates towards the push-back magnet, and as a result the rotations of the magnet create alternating voltage between ends of the coil.

Abstract: A harvesting system that includes a dynamo with a rotor and a stator, a push magnet that is attached to the rotor or is a part of it, a moving magnet that moves from a first position to a second position, and a push back magnet. The repulsive magnetic force that is exerted by the moving magnet on the push magnet in the second position is greater than that force in the first position. The moving magnet moves from the first position to the second position and causes the rotor to rotate from a dynamo first position to a dynamo second position that causes the dynamo to produce current. When the moving magnet moves back to the first position the dynamo returns to its first position due to magnetic force that the push back magnet exerts on the push magnet.

Abstract: A method and system for measuring a load on a tire while the vehicle traveling that include a microprocessor, a tire pressure sensor that is fixed to the tire, and an electromechanical sensor that is fixed to a point on the tire. The electromechanical sensor generates a beginning signal when the point begins to be part of the flat tire contact patch of the tire with the ground, and an ending signal when this point ceases to be part of the patch. The microprocessor calculates the patch contact time period, calculates the flat tire contact patch length from the radius of the tire and the ratio between the patch contact time period and the complete tire rotation period, and calculates the load on the tire from the tire pressure as measured by the pressure sensor and the length of the flat tire contact patch.
