Abstract: A system for sensing current in one or more first electrical conductors includes a frame and a retainer configured to receive the one or more first electrical conductors and constrain relative movement between the one or more first electrical conductors and the frame. The system may also include a first magnetoresistive sensor configured to sense magnetic flux and generate an output signal relating to the sensed magnetic flux. Additionally, the system may include an adjustable positioning system configured to enable supporting the first magnetoresistive sensor from the frame in any of a plurality of possible positions with respect to the retainer.

Abstract: A pressure washer wand is connectable to a source of fluid. The pressure washer wand includes a housing that defines an interior and a flow path disposed substantially within the interior. The flow path includes an inlet in fluid communication with the source and an outlet. A valve at least partially defines a portion of the flow path and is movable between a closed position and an open position in which fluid travels from the inlet to the outlet. A user interface is movable between an actuated position in which the valve is open and a non-actuated position in which the valve is closed. A lock member is substantially disposed within the interior and is movable between a locked position in which the lock assembly inhibits movement of the user interface, and an unlocked position.

Abstract: An electrical system includes a first monolithic circuit. The first monolithic circuit may include a first magnetoresistive sensor operable to sense magnetic flux and produce an output signal relating to the sensed magnetic flux. The first magnetoresistive sensor may be positioned to sense first control flux generated by control current in one or more electrical conductors of the first monolithic integrated circuit. Additionally, the first magnetoresistive sensor may be positioned to sense flux generated by sensed electric current flowing through one or more additional electrical conductors. The electrical system may also include a control circuit operable to receive the output signal of the first magnetoresistive sensor and adjust the control current that generates the first control flux in a manner to cause the output signal from the first magnetoresistive sensor to substantially coincide with a predetermined target.
