  • Patent number: 10428629
    Abstract: Systems and methods are disclosed for extracting underground objects using a beam pumping unit including a rotating motor and one or more cranks coupled to a walking beam enabling the extraction. According to certain embodiments, the method includes receiving, at a control system, one or more input signals; and providing, based on the input signals, one or more control signals to the rotating motor to enable the rotating motor to directly drive the one or more cranks for extracting the underground objects. The method also includes varying, based on the one or more control signals, a rotating speed of the rotating motor based on one or more conditions of the underground objects; and enabling the extraction in a reciprocated manner based on the varying rotating speed of the rotating motor.

  • Patent number: 10364794
    Abstract: A wheel-hub driven wind turbine apparatus is disclosed. One embodiment of the apparatus may include a body and at least one vertical-axis wind turbine blade mounted on the body to translate wind forces exerting on the at least one vertical-axis wind turbine blade to the body, causing the body to move. The apparatus may also include at least one wheel-hub attached to the body and configured to rotate when driven by the movement of the body. The apparatus may also include at least one generator coupled to the at least one wheel-hub to generate electrical power when driven by the rotation of the at least one wheel-hub.
