Abstract
In one aspect, a wireless transceiver is used to wirelessly connect various electrohydraulic components in a hydraulic system. In another aspect, a self-powered wireless hydraulic system includes a harvesting device for converting hydraulic energy into electrical energy. The electrical energy generated by the harvesting device can be used to power one or more electrohydraulic components and wireless transceivers. In another aspect, a self-powered wireless hydraulic system also includes a flow control device powered by the harvesting device for actively controlling the hydraulic flow through the harvesting device.
