Abstract: A communication system includes an optical “LAN” (50) interconnecting a plurality of information sources (16a) and sinks (22a) with a light-to-electrical converter (36a) associated with an electrical RF transmitters (32a) and an RF-to-light converter (38a) to a receiver (34a). The transmitter is coupled by way of electrical-to-light converter (46a), and the receiver is coupled by way of light-to-electrical converter (44a), and by way of a directional coupler (76a), to an end of an optical bus (74a), so that light signals representing signals to be transmitted flow in one direction, and light signals representing received signals flow in the other direction through the bus. A directional coupler (72a) at the other end of the optical bus routes the transmit light signals to a light-to-RF converter (47a) which feeds a sink or antenna (12a), and received signals from a source or antenna are routed by way of an RF-to-light converter (40a) and the directional coupler (72a) onto the optical bus (74a).

Abstract: A current transformer for a ground fault circuit breaker used on a circuit having at least one line conductor and a neutral conductor includes a toroidal core having a circular opening defining a center point and a multi-turn winding wound on the core. A first guide member is disposed on one side of the core, and a second guide member is disposed on another side of the core. The first and second guide members each have a hole for receiving the line conductor and a hole for receiving the neutral conductor formed therein. The guide members thus position the conductors with respect to the core. The present invention also includes a method of correcting asymmetries in the current transformer. The method includes measuring the magnitude and orientation of any asymmetries, and then altering the current transformer based on the measured magnitude and orientation of the asymmetries so as to eliminate the asymmetries.

Abstract: A rotary doser valve includes a stator with a plurality of ports therein which cooperates with a rotor having a plurality of channels therein. The rotor is rotatable against the stator in first and second positions which alternately channel water to and from a doser for refilling an icemaker in a preferred use.

Abstract: The fail-safe electronic circuit breaker includes a test circuit connected to a fault detection circuit. The test circuit selectively generates a simulated circuit fault that is supplied to the fault detection circuit. The fail-safe electronic circuit breaker also includes a trip mechanism disabler that is connected to the test circuit. The trip mechanism disabler permanently disables the fail-safe electronic circuit breaker when the fault detection circuit fails to detect the simulated circuit fault after about a predetermined amount of time.

Abstract: An analog to digital conversion circuit for converting an analog input signal into a plurality of binary output bits includes an operational amplifier and an integrating capacitor for storing a charge proportional to the integral of the input signal. A charge subtracting circuit removes a first predetermined charge from the integrating capacitor when an output charge of the operational amplifier is substantially equal to a second predetermined charge. The first predetermined charge level is removed from the integrating capacitor a number of times. The removal of the first predetermined charge from the integrating capacitor allows the integral of the analog input signal to be larger than a maximum charge capable of being stored by the integrating capacitor.

Abstract: A method for removing “grid line artifacts” from x-ray images without changing the diagnostic quality of the x-ray image is presented. The method utilizes the Fourier spectrum of the image to detect the grid line frequencies and employs spectral domain filtering to remove the grid line spectral components. The diagnostic information is preserved by modifying the grid line spectral components to be indistinguishable from local variations in image intensity values, and edge density of the x-ray image.
