Abstract: The present invention provides a fractional order sliding mode synchronous control method for a teleoperation system based on an event trigger mechanism. The method comprises: establishing a dynamics model for the teleoperation system by considering external disturbance and parameter uncertainty, selecting a master robot and a slave robot, interactively establishing the teleoperation system through a communication network, determining system parameters of the dynamics model, designing a fractional order nonsingular rapid terminal sliding mode surface equation by utilizing a position tracking error and a fractional order calculus, setting a trigger event condition of information interaction between the master robot and the slave robot, designing a self-adaptive fractional order nonsingular rapid terminal sliding mode controller based on the sliding mode, designing a Lyapunov function to carry out stability analysis, proving the boundedness of a closed-loop state signal of the system.

Abstract: A pipe for use in a geothermal heat exchange system is disclosed that is insertable into a bore hole having a proximal end and a distal end. The pipe has a proximal end, a distal end and an outer wall member. The outer wall member includes an external surface, and an interior surface defining an interior passageway through which a heat exchange fluid can flow. The pipe also includes a divider extending between opposed points of the interior surface for dividing the interior passageway into an inflow passageway for conducting water from the proximal end to the distal end of the pipe, and an outflow passageway for conducting water from the distal end to the proximal end of the pipe. The divider segregates the water in the outflow passageway from the water in the inflow passageway.

Abstract: A grounding component is provided for grounding electronic components. The grounding component includes: a base; a channel formed within the base; and a spring finger extending from the base, the spring finger having a fixed end and a free end. When the spring finger is in a first undepressed position, a knuckled portion of the spring finger lies proud of the base, and the free end of the spring finger lies substantially within the channel. A method for manufacturing the grounding component is also provided.

Abstract: An assembly system includes an electronic component, a gripper, and a socket. The electronic component has sides and a top face, the top face has a top-face peripheral area and a top-face central area. The gripper has a gripper head, the gripper head being movable to an open and closed position. The gripper head has an extension configured to contact opposing sides of the electronic component when the gripper head is in the closed position, and a surface configured to contact the top-face peripheral area of the electronic component when the gripper head is in the closed position. The socket has a top peripheral surface. An insertion depth guide is associated with the gripper head and has a depth guide with a bottom surface configured to contact the top peripheral surface of the socket. A method for assembly is also included.
