Title: Systeme de controle d'un systeme bitension sans mise a la terre
Inventor: BENESH STEPHEN PATRICK
IPC: G01R31/02

Abstract: Dispositif logé sur un seul et même panneau isolant, permettant de déterminer les fuites d'un système multiphase à double tension non relié à la terre. Le système met en oeuvre un seul et unique transformateur isolant comprenant des enroulements secondaires doubles produisant les tensions doubles. Un premier organe de contrôle d'isolation de ligne (LIM) est constitué par un microcontrôleur sur base qui mesure de manière continue l'impédance de défaut de l'une des tensions de sortie du système multiphase, isolé ou non, relié à la terre. Un deuxième LIM mesure en continu l'impédance de défaut de l'autre tension de sortie du système. L'impédance de défaut est déterminée par le LIM en injectant un courant de mesure à ondes sinusoïdales continu dans une borne de terre pour produire une tension de mesure au travers de l'impédance de défaut. Sur la base de la mesure de la tension et de l'intensité, le LIM calcule l'impédance de défaut et, sur la base de cette impédance, calcule les fuites sur la base de la tension maximale ligne/terre du système non relié à la terre. La fuite est affichée et, lorsqu'elle excède une certaine valeur, le LIM déclenche une alarme sonore et visuelle. Une voie de télécommunications série permet au LIM de communiquer avec d'autres dispositifs intelligents. Le LIM comporte un dispositif d'auto-étalonnage et d'auto-test en cours de fonctionnement et pendant une séquence d'intensification de puissance. La fréquence de ligne est également déterminée par le LIM. Les deux LIM peuvent être utilisés pour observer le système de distribution double de manière simultanée, sans interférence de l'un sur l'autre.

Abstract: An educational method for teaching written composition is demonstrated within a series of hand-held, rectangular manipulatives encoded with raised, colored indicia. Representing a foundation from which all types of writing may be explored, the manipulatives have been so designed that continuity of theme and flow of composition is ensured. Each rectangular manipulative symbolizes a paragraph in written composition. Colored bands framing the manipulatives identify paragraph themes and subsequent order within a composition. The raised, color-coded indicia represent key sentences within a paragraph and is so ordered as to clearly outline proper sentence sequencing. The manipulatives, used individually or interactively, provide a focus for critical elements of successful writing through enjoyable visual and tactile stimulation. Traditional writing concepts and language structure rules are reinforced and solidified in an objective, non-threatening manner. This innovative educational method has cross-curricula applications and may be taught to groups or personally tailored to address the specific needs of individuals. Freedom of expression, individual writing style and creativity are provided within the theory and application of this invention.

Abstract: An apparatus for simultaneously stabilising the output power and wavelength of a semiconductor laser is disclosed. A wavelength discriminating scheme is used to provide a wavelength error signal and an output power detection scheme is used to provide an output power level signal. The wavelength error signal is used to adjust the behaviour of a temperature sensor such that an automatic temperature control (ATC) module configured to maintain a pre-determined output from the temperature sensor, adjusts the actual laser temperature to minimise said signal. The output power level signal is directly delivered to an automatic power control (APC) module, which adjusts the drive current fed into the laser to minimise said signal using known control circuitry means. Adjusting the properties of the temperature sensor makes it possible for the apparatus to manipulate laser temperature and current to achieve simultaneous power, wavelength and temperature control, using the constant-temperature and constant-power external control modules used by semiconductor lasers that do not stabilise wavelength.
