Abstract: A method for positioning a movable reflector in an optical switch. A set of optical power values are generated by measuring optical power related to optical reflections from the movable reflection for a plurality of positions of the movable reflector. A processor is used to generate a mathematical approximation of a relationship of optical power versus reflector position based on the set of optical power values. A position of the movable reflector is chosen based on a point in the mathematical approximation of the relationship of optical power versus reflector position.

Abstract: A method for ensuring path integrity in an optical switch is provided that essentially eliminates any occurrences of misconnected paths and enables new signal paths to be easily generated and existing paths to be switched. The method is suitable for use in optical switching devices that enable selective connection of optical signals received on a plurality of input fibers to respective output fibers, wherein the optical switching device includes a first array of mirrors disposed in a first mirror plane and a second array of mirrors disposed in a second mirror plane. In accordance with the method, all mirrors are maintained in signal paths so that undesired light is prevented from reaching any of the output fibers.

Abstract: A system and method for speech-responsive voice messaging, in which a Speech-Responsive Voice Messaging System (SRVMS) preferably provides a hierarchically-simple speech user interface (UI) that enables subscribers to use speech to specify commands such as mailboxes, passwords, and digits. The SRVMS generates and evaluates candidate results. The SRVMS invokes a speech UI navigation operation or a voice messaging operation according to the outcome of the evaluation of the candidate results. In the preferred embodiment, the SRVMS determines whether the candidate results are good, questionable, or bad; and whether two or more candidate results are ambiguous due to a likelihood that each such result could be a valid command. If the candidate results are questionable or ambiguous, an ambiguity resolution UI prompts the subscriber to confirm whether the best candidate result is what the subscriber intended.

Abstract: The invention is directed to a rapid, efficient, inexpensive screening and diagnostic procedure for detecting avermectin/milbemycin resistance in parasitic nematodes. The procedure is designed for field use. The method entails the incubation of nematode sensillum with specific visible or fluorescent dyes that intercalate and diffuse in membranes of sensory neurons on the outer surface of wild-type nematodes but which do not bind or have reduced binding in resistant nematodes. The method is particularly directed to ivermectin resistant parasitic nematodes.

Abstract: A stator of a rotary electric machine is supported in a housing structure and is secured therein against relative rotation or axial movement by angularly spaced fasteners. A circumferential passage in the stator communicates with a supply passage for liquid coolant. The temperature coefficients of expansion of the materials of the housing and the stator differ so that below a predetermined temperature those parts are an interference fit, and above that temperature channels are created between the fasteners, through which channels coolant can flow axially from the passage.

Abstract: A coupling for use in a transmission system and between coaxial rotary members which are arranged for driving engagement through axially engaging teeth thereon, one of said members being connected, directly or indirectly by helical splines to a further part such that in normal rotation, the said one member has a force exerted upon it tending to separate the teeth, such force being resisted by a fusible element which will melt when temperature rises above a predetermined value, melting of said element permitting axial movement of said one member relatively to said further part, through the splines to permit disengagement of the teeth, bearings supporting said further part, being substantially free from axial loading and spring means being provided for preventing re-engagement of the teeth after the element has melted.

Abstract: An electric generator arrangement comprises a generator and a continuously-variable ratio drive, whereby the generator can be driven at a constant speed over a range of speeds applied to an input shaft. The drive comprises an epicyclic differential gear having a planet gear carrier driven by the input shaft, a sum gear coupled to coupled to the generator and a ring gear. The ring gear can be driven at varying speeds by hydraulic units to vary the ratio of the speeds of the input shaft and the sun gear. The hydraulic units are driven by the input shaft and the speed of the ring gear is controlled by an electro-hydraulic control system which is responsive to the frequency of an output signal from a part of the generator. Fluid under pressure for the hydraulic units and the hydraulic control system is provided by a combined pump and de-aerator on the shaft of another part of the generator.
