A pump jack controller is provided that can harness the potential energy generated during the operation of one pump jack amongst a plurality of pump jacks located at a well site and convert that potential energy into electrical energy that can be used to provide electrical power generated by the pump jack to power the other pump jacks located at the well site.

A method for capturing energy from an oscillating object, in which at least one unbalanced rotor is oscillated to rotate the rotor(s) while reciprocally pivoting each of the rotor(s) about a respective counter-oscillation axis that is substantially perpendicular to both a rotation axis of the rotor and the oscillation axis for the oscillating object. Reciprocally pivoting the rotor(s) about the respective counter-oscillation axis urges the rotor to rotate continuously instead of reciprocally, and energy from rotation of the rotor can be captured, for example mechanically or electrically. Optionally, the counter-oscillation axis may be moved to maintain the counter-oscillation axis perpendicular to the oscillation axis for the oscillating object.

The present disclosure relates to a swing bearing and a wearable device. The swing bearing includes an inner ring, an outer ring, and a plurality of rolling elements, a plurality of first grooves arranged at intervals along a circumferential direction being formed on an outer circumferential surface of the inner ring, a plurality of second grooves arranged at intervals along a circumferential direction being formed on an inner circumferential surface of the outer ring, each rolling element being disposed between the corresponding first groove and the second groove, and the rolling element, the first groove, and the second groove being configured to restrict relative rotational movement between the inner ring and the outer ring and allow the inner ring and the outer ring to produce shaft axis deflection movement.

The present invention concerns a mechanism (1), comprising: one support (2) including a base (3), one pendulum (4), and connecting suspension rods (5) articulated on the base (3) and on the pendulum (4); two mobile cog wheels (12; 22) in rotation around their respective axis (A1; A2); two eccentric elements (14; 24) integral with the cog wheels (12; 22) in rotation and generating moments of gravity force around their axis (A1; A2); and one connecting link rod (60; 160) comprising a rotary head (62) and an eccentric head (63). The axis (A1; A2) are parallel within a horizontal or vertical reference plane (P0). The pendulum (4) supports the axis (A1; A2) of the cog wheels (12; 22) and of the eccentric elements (14; 24). The connecting rods (5) are slanting in accordance with an angle comprised between 45 degrees and 80 degrees in relation to a vertical plane. The cog wheels (12; 22) engage one with the other using a unitary transmission ratio and are mobile in rotation in opposing directions. When the mechanism (1) is in operation, the eccentric elements (14; 24) follow an elliptical movement, whereas the pendulum (4) follows a travel movement having a vertical component and a horizontal component. The moments of gravity force of the eccentric elements (14; 24) have a same value and a same direction, both being variable depending on their angular position around the axis (A1; A2). For each angular position of the cog wheels (12; 22) and of the eccentric elements (14; 24) around the axis (A1; A2), the mechanism (1) presents an equilibrium configuration at rest.

The invention provides a mechanical apparatus comprising: a main wheel rotatable about a main axis; four radially spaced pendulum axes parallel to and around the main axis, and four pairs of weighted pendulums. Each pair is mounted to the main wheel for 360° rotation about a separate pendulum axis. A latching mechanism associated with each pendulum pair releasably but independently holds one or both pendulum of a pair at one or more rotational position, the engagement and/or release of a pendulum by a latching mechanism being operated by the movement of pendulums within the same or other pairs and/or by the rotation of the main wheel. As the main wheel rotates about the main axis the pendulums rotate about the pendulum axes under the control of the latching mechanism.
