Abstract: A loader can include a lift arm structure coupled to a frame. The lift arm structure can move between a fully-lowered position and a fully-raised position and can include a lift arm and a connecting link. A first end of the connecting link can be pivotally coupled to the frame at a first pivot point and the lift arm can be pivotally coupled to a second end of the connecting link a second pivot point. The lift arm structure can further include a lift actuator configured to pivot the lift arm about the second pivot point and an extension actuator configured to pivot the connecting link about the first pivot point. The extension and lift actuators can be controlled to move the lift arm along a variety of travel paths between any two points within a lift envelope of the lift arm structure.

Abstract: A power machine can include a frame, a power source, one or more workgroup actuators, and one or more tractive assemblies secured to the multi-piece frame. The frame can include a base frame and a bridge frame. The bridge frame can support the one or more actuators and the one or more tractive assemblies relative to the base frame. The tractive assemblies can include one or more drive actuators that is supported by the bridge frame. The base frame can support the power source relative to the bridge frame.

Abstract: An optical fibre arrangement has at least two optical fibre sections, each optical fibre section defining an outside longitudinally extending surface. The outside longitudinally extending surfaces are in optical contact with each other. The invention further provides for an amplifying optical device have an optical fibre arrangement as just described, and a pump source. The amplifying optical device is configured such that the pump source illuminates the amplifying optical fibre. A amplifying arrangement is also disclosed. The amplifying arrangement includes a plurality of amplifying optical devices as just described, and each amplifier also has at least one input fibre and a first multiplexer connected to the input fibre. Each amplifier is configured such that at least one of the amplifying optical fibres is connected to the first multiplexer. The amplifying arrangement also has a second multiplexer connected to each of the first multiplexers.

Abstract: Utility consumption data is provided over power line carrier links to local nodes and routed through a network of local nodes over peer-to-peer line-of-sight RF links to a utility service provider. Backhauler nodes combine the utility consumption data from the local nodes within a coverage region for routing to the utility service provider. Consumer nodes include sensing elements for measuring the utility consumption data, and switching elements for connecting or disconnecting the utility from a consumer location. Messages are sent through the network requesting the utility consumption data and for activating the switching elements.
