Abstract: Arc fault detector device (such as arc fault circuit interrupter) testing apparatus and methods including generating a true arc fault current by energizing a contact relay at a predetermined frequency, applying and regulating the true arc fault current to a detection device under test by selecting a load from a resistor bank that is coupled to the tested device, determining whether the device under test was able to detect the arc fault current. The invention is useful for determining whether an arc fault circuit interrupter is capable of tripping in response to an arc fault current.

Abstract: An all-optical semiconductor waveguide optical regenerative device uses a nonlinear ridge waveguide structure to mix an input signal with a local oscillator signal to produce wavelength-switched and optically-regenerated signals. The ridge waveguide structure, and the local oscillator sources, filters and amplifiers may be tunable, microprocessor-controlled and monolithically integrated. The present invention relates to semiconductor waveguide-based structures, photonic application-specific integrated circuits, which can be used for optical signal processing and, more particularly wavelength-conversion, wavelength-shifting, wavelength-translation, wavelength-switching, wavelength-routing and optical signal transmission, amplification, pulse-shaping and regeneration in optical networks by integrating multiple functions on monolithic semiconductor substrates of Indium Phosphide and its ternary and quaternary semiconductor material derivatives.

Abstract: The apparatus has two main regions of members the operation of which is controlled separately, the first region, to which the user has interactive access, permitting loading of the samples, controls, calibrators, diluents and other equipment for performing the sampling and dilutions and receiving the plate on which the tests are performed, and the second region, to which the user has occasional access, comprising stations dedicated to the rest of the process including incubation, washing, reading, and others, the second region being able to hold several plates at different stages of the process, the apparatus having means for automated movement along three coordinate axes X, Y, Z in order to transport the reagents and the plates in order to complete the process, enabling several tests to be performed at the same time on a set of samples in one or several plates, and enabling new series of tasks with the same or different sets of tests and with the same or different sets of samples to be started when the previ
