A feedwell assembly is provided to assist in evenly distributing a source liquid to a clarifier and for dissipating the energy of the source liquid during flocculation is provided. The array of main capacitive sensors gives the ability to measure the levels of insoluble liquids in a vessel. The linkage mechanism is actuated to rotate and then to drive a second actuator to slide on the second housing and the second actuator forces a supporter, which pivots to the second housing, to open at a predetermined angle relative to the second housing. The system and method are accessible through a web browser or mobile application. A transmitter is arranged externally of the patient’s body for supplying signals transcutaneously to the receiving device of the stimulator. , to convert it into a completely crystallized transparent conductive layer having a Hall mobility of 30-45 cm2V\xb7S and a carrier density of 2\xd71020cm3 to 7\xd71020cm3.
