Abstract: A single, continuous strand of fiber optic material 32 is wrapped about a mandrel 70 to form oval-shaped loops having parallel sides 82, 84. 88, 92 and curved ends 78, 83, 86, 90. A magnet 100 is positioned so that its B-field is substantially parallel to the straight portions 82, 84, 88, 92 of the loops. As light propogates through these straight portions 82, 84, 88, 92 of the loops, its direction of polarization is rotated in accordance with the Faraday effect. The curved portions 78, 83, 86, 90 are formed to create sufficient linear birefrigence to provide a phase difference ot 180 degrees between light in the two orthogonal polarization modes of the fiber 32. This causes the Faraday rotations in each of the straight portions 82, 84, 88, 92 to add, rather than cancel.The magneto-optic rotator of the present invention is useful in a variety of applications such as an optical isolator, a modulator, and a magnetometer.

Abstract: An immersion detection current interrupter circuit with an electric latch for use in small electrical appliances. A sensor wire (W) is positioned within an appliance to sense current leakage when in contact with a conductive fluid. A relay or solenoid (R) connected to the sensor is positioned between the load leads (R) in a latch circuit. When the sensor detects a leakage current, it causes a two-pole double-throw relay to latch, breaking the load lines beyond the relay (R). The relay will remain latched untill the power cord is unplugged or reset by a switch which opens and closes the power lines. Once the component has latched, the maximum leakage current will be limited by the voltage drop across a diode (D5).
