Abstract: An electric vehicle suitable for use in mining, the electric vehicle comprising at least one electric motor for providing motive power to the vehicle, at least one battery for supplying electricity to the at least one electric motor, a connector for connecting to an electrical conductor, whereby the electrical conductor provides electricity to the battery and/or vehicle when the connector is connected to the electrical conductor, wherein the battery has a power density of from 5000 to 20,000 W/kg and an energy density of from 5 to 100 Wh/kg. The battery may include tungsten oxide battery chemistry.

Abstract: System (1) for electrically feeding electrically powered vehicles (2a-b), comprising electric conductor(s) (3) extending along a road section (4) and a central electronic control unit, CECU (8). The vehicles comprise a current collector (5a-b), an onboard energy storage device (7a-b) and a thereto connected vehicle electronic control unit, VECU (6a-b). The VECU is configured to determine a current required power and a current energy storage status, and to send a signal to the CECU indicating the current required power and the energy storage status. The CECU is configured to determine a maximum power available via said electric conductor and a power to be received for each vehicle such that the maximum power is not exceeded and send at least one power control signal to each VECU indicating the power to be received. The VECU is configured to control received power in response to said at least one power control signal.

Abstract: A polypectomy instrument for the resection and withdrawal of a polyp tissue from a body lumen. The instrument comprises a dual handle arrangement on a first proximal end of the polypectomy instrument and a plurality of working channels on a distal end of the dual handle arrangement. Each of the working channels are arranged to carry a polyp engaging device. The dual handle arrangement is arranged to permit the easy manipulation and distally advancement and proximal retraction of the polyp engaging devices simultaneously.

Abstract: Motion of an articulated figure in response to an external force function and to a co-acting internal force function is simulated, for use in computer animation. The internal force function is defined by applying an inverse-dynamic method to solve for internal forces driving the articulated figure to conform to a predefined animation curve. The internal force function may be scaled in any desired way, an combined with the external force function as input for a forward-dynamics motion simulation. The resulting motion simulation models a combined effect of the external force function and the predefined animation curve on motion of the articulated figure.
