    Abstract: A coil assembly (10) includes a plastic bobbin (12) with wire (30,32) coiled thereon and coupled to the pins (38, 48, 54) of a connector (40). Plastic overmolding (60) covers wires (30,32) within bobbin (12) and fixes connector (40) relative to bobbin (12). A polyester bobbin (12) is made by injecting polyester into a mold having cavities (101, 151) to define the outer circumference of the bobbin and surrounding an arbor (106, 160) to define the inner circumference of the bobbin. The arbor (106, 160) with the molded bobbin (12) is removed from between the cavities (101, 151) and the bobbin (12) is slid laterally off the arbor by applying generally uniform pressure about a lateral edge (20, 22) of the bobbin so as not to warp same during the removal process.

    Abstract: A non-intrusive fluid level detector including a single point capacitive sensor (C4) mounted on the outside surface of a receptacle (10) such that capacitive principles can be utilized to sense the level (1, 2) of a liquid contained within the receptacle (10). The sensor assembly is disposed in a substantially fixed position on the exterior wall of the receptacle (10) wherein the dielectric effect of the liquid changes the effective capacitance of the sensing capacitor (C4) as the liquid rises and falls within the receptacle (10). This change in effective capacitance is detected by electronic circuitry included in the detector device. In one embodiment, the fluid level detector is directly mounted to a completely non-conductive receptacle (10). In another embodiment, the fluid level detector is mounted to a non-conductive window (12) which is an integral part of a receptacle fabricated out of a conductive material.
