Abstract: ABSTRACT A bi-directional, fiber optic coupler operative to receive from an optical fiber, modulated light for detection thereof, and for applying to the same fiber, modulated light for transmission to a remote location.  The coupler comprises a body which can be conveniently and economically molded as a unitary plastic element and in which V-channel is formed to receive and securely hold the optical fiber. The channel terminates in a slanted reflecting face which is readily coated with a dielectric layer to provide a beam splitting function, or in the case of dual frequency transmissions, a frequency dependent layer to provide multi-plexing or demultiplexing.  The slanted reflecting face is located at the bottom of an emitter cavity in which an emitter assembly is readily press-fit to provide predetermined alignment between light eminating from the emitter assembly and the reflecting face from which the light is reflected into the adjacent termination of optical fiber. A detector cavity is formed within the body and position to receive light passing through the reflecting face. the transiting light is refracted downward toward the detector cavity which is positioned off axis. An index of refraction matching material may be applied between the optical fiber and reflecting face in which case the reflecting face passes the incoming light directly along the axis. A portion of the transmitted light is totally internally reflected by the bottom surface of the emitter cavity which is formed to provide a mirror surface than redirects that light toward the detector cavity. a lens may be molded directly into the coupler body to gather light passing through and refracted by the reflecting face.  For the portion of light generated by the emitter and passing through the reflective face, a reflective wedge is provided in the bottom of thecoupler body to direct that radiation away from the detector to reduce cross talk.

Abstract: ABSTRACT OF THE DISCLOSURE          A voltage regulator is described adpated for use controlling the output of an AC generator.   A voltage control field-winding excitation control circuit supplies direct current to the generator field in response to a driver.  The driver, in turn, is operated in response to a switching regulator.  A frequency sensing means generates a voltage proportional to the frequency of the generator. This  frequency  sensitive  voltage  is  combined  with  a reference  voltage  to  drive  an  asynchronous  switching regulator.  The switching regulator produces a train of output voltage control  signals  to operate  the driver. Perferably power MOSFETs are used to control the flow of current to the generator field.  Loss of voltage and high current protection features are included.

Abstract: ABSTRACT OF THE DISCLOSURE Method and apparatus for monitoring and diagnos-ing sensor and interactive based process systems.  The knowledge base concerning the process system per se is in the form of a list stored in memory, which list includes domain specific rules in evidence-hypothesis form.  This domain dependent information is devoid of means for inter-connecting the rules to perform diagnostic services. A completely domain independent set of meta-level rules is stored in memory, which, in response to sensor and/or user input, searches the knowledge base and effectively con-structs a rule network through which belief is propagated, to detect and report malfunctions, to output control signals for modifying the operation of the monitored system, and to aid users by providing information relative to malfunctions which pinpoints probable causes.  The domain independent rules, in addition to the meta-level rules which search the knowledge base and interconnect domain specific rules, includes procedural rules for choosing which of the meta-level rules to apply when there is a choice.  The procedural inference rules are indepen-dent and distinct from the meta-level rules which manipu-late the knowledge base.
