摘要： The present disclosure describes a control system network architecture for a fluidic control system such as a hydraulic or pneumatic control system. The architecture includes a plurality of clustered control-component nodes with each node being alternatively configurable to independently control the operation of multiple single-acting controlled endpoint devices or a double-acting controlled endpoint device. Each node includes control-components including a solenoid, one or more valve spools independently controllable by the solenoid, and a low-level controller operable to control the solenoid. The solenoid, valve spools, and low-level controller are clustered together and physically co-located as a unit. The nodes are arranged in a control block with each node being uniquely identifiable for data communication via a data communication network. The data communication network may include a Controller Area Network (CAN). Multiple control blocks may be equipped with communication modules and linked for data communication between the control blocks.

摘要： A position sensor and a method for sensing a position of a moveable member includes at least first and second deflectable members arranged so as to allow the moveable member to pass therebetween and cause the at least first and second moveable members to deflect in proportion to the position of the moveable member relative to the first and second deflectable members. In one example of the present invention, the deflectable members are cantilever-mounted members extending in generally the same direction. The amount of resultant deflection is measured by any suitable means. For example, each deflectable member may have a Wheatstone bridge provided thereon acting as a strain gauge in a known manner, such that the strain detected is proportional to the amount of deflection. In a particular example of the present invention, some of the elements of a first Wheatstone bridge are provided on the first deflectable member and some are provided on the second deflectable member. Likewise, some of the elements of a second Wheatstone bridge are provide on the first deflectable member and some are provided on the second. This desirably provides matched redundancy as well as compensation for spurious lateral movement of the moveable member.
