Patent CA-2401771-A1 (CA)
Title: Electro-optic voltage sensor
Inventor: RENAK TODD W
IPC: G01R19/00
Filed: 1996-12-05
Abstract: An electro-optic voltage sensor for achieving voltage measurement without significant error contributions from neighboring conductors or environmental perturbations. The voltage sensor includes a transmitter (1), a sensor (4), a detector (43, 44) and a processor (62). The transmitter (1) produces a beam of electromagnetic radiation which is routed into a sensor (4). Within the sensor (4), the beam undergoes the Pockels electro-optic effect. The electro--optic effect produces a modulation of the beam's polarization, which is in turn converted to a pair of independent conversely-amplitude-modulated signals, from which the voltage of the E-field is determined by the processor (62). The use of converse AM signals enables the signal processor (62) to better distinguish signal from noises. The sensor (4) converts, the beam by splitting the beam in accordance with the axes of the beam's polarization state (an ellipse whose ellipticity varies between -1 and +1 in proportion to voltage) into at least two AM signals. These AM signals are fed into a signal processor (62) and processed to determine the voltage between ground conductor and the conductor (2) on which voltage is being measured.

Title: Procede de moulage dynamique
Inventor: VARMA DEVANAND
IPC: B29C49/02
Filed: 2001-03-13
Abstract: L'invention concerne un procédé et un appareil de moulage dynamique, ainsi que le produit obtenu. Ce procédé permet d'effectuer deux ou plusieurs étapes (processus initial) de façon simultanée. Une machine de moulage par soufflage et une machine de moulage par injection peuvent être utilisées dans le même moule et être exploitées en même temps. Le moule utilisé dans le procédé de moulage dynamique peut être divisé en plusieurs parties ou posséder plusieurs filières dans sa structure. Les filières peuvent se déplacer afin de permettre à la pièce de sortir du moule et de se déplacer, de façon à effectuer plusieurs étapes l'une après l'autre. Afin de satisfaire les exigences de fabrication en termes de cisaillement, de thermodynamique et de température, par exemple, et d'obtenir un produit de qualité et un coût de conception réduit, deux ou plusieurs procédés doivent être mis en oeuvre de façon rapprochée. Ce procédé de moulage dynamique peut être utilisé dans des applications métalliques incorporant aussi des applications d'hydroformage, de poinçonnage et de forgeage, etc. Ce procédé est ouvert à tous les procédés de fabrication connus appliqués aux métaux, aux plastiques, à la céramique et au verre, également sous forme de pastilles, et les particules d'alimentation sont limitées de façon à obtenir un produit et un procédé sûrs. Les produits obtenus sont de nouveaux produits applicables aux produits actuels, réduisant le travail et l'outillage et, par conséquent, le coût. Le procédé de l'invention facilite, par exemple, le recyclage et la protection de l'environnement. L'existence d'un plus grand nombre de récipients plastiques pour boissons froides ou chaudes va permettre de réduire le coût des plastiques de façon considérable, et de réduire le coût du recyclage en raison d'un nombre moindre de produits à recycler.

Title: Selectively pressurized structural member for vehicle body and frame assembly
Inventor: VALDEZ JUAN F
IPC: B62D21/15
Filed: 2003-09-22
Abstract: A vehicle body and frame assembly includes a closed channel structural member having an interior portion that can be pressurized under certain conditions, such as during a collision, to provide increased strength and absorb energy. A pressurizing device communicates with the interior portion and contains a quantity of a chemical material that, when properly excited, will expand rapidly into a gaseous form. An igniter or other structure is provided for exciting the chemical material contained within the pressurizing device under predetermined conditions, such as when a collision occurs. The expansion of the chemical material into a gaseous form rapidly increases the air pressure within the closed channel structural member, thus providing additional strength thereto to absorb energy during the collision.  Although deformation of the closed channel structural member may occur as a result of the expansion of the chemical material, it is the containment of the highly pressurized gases within the closed channel structural member that increases the strength thereof during the collision.
