Patent CA-2335942-A1 (CA)
Inventor: FORREST STEPHEN R
IPC: H01S5/50
Filed: 1999-06-23
Abstract: An asymmetric twin waveguide (ATG) structure (11) significantly reduces the negative effects of inter-modal interferences in symmetric twin-waveguide structures and which can be effectively used to implement a variety of optical devices. The ATG structure (11) of the invention can be monolithically fabricated on a single epitaxial structure without the necessity of epitaxial re-growth. The effective index of the passive waveguide in the ATG is varied from that of a symmetric twin waveguide such that one mode of the even and odd modes of propagation is primarily confined to the passive waveguide and the other to the active waveguide (71). The different effective indices of the two coupled waveguides result in the even and odd modes becoming highly asymmetric. The mode with the larger confinement factor in the active waveguide (71) experiences higher gain and becomes dominant. Furthermore, a grating region is incorporated atop the passive waveguide (125) to select certain frequencies for transmission of light through the passive waveguide (125).

Title: Detecteur d'inclinaison a controle continu
Inventor: JIANG SHUSHENG
IPC: G01C9/06
Filed: 2000-09-06
Abstract: Capteur résistant et incurvé imprimé sur un substrat en céramique (13) constituant une paroi d'un corps en céramique contenant, de façon totalement étanche, un électrolyte (12), plus particulièrement du nitrate d'argent, dissous dans un mélange de méthanol, d'eau et de butanol. Dans le but d'éliminer les effets de l'électrodéposition, on applique une tension d'excitation de courant alternatif entre les extrémités du capteur couplée par une résistance de décharge (30) dont la résistance est beaucoup plus basse que la résistance interne du capteur, de manière à dissiper toute polarisation provoquée par l'asymétrie de l'alimentation en tension. On prend une sortie de signal depuis un point médian du capteur (19) qui est toujours immergé dans l'électrolyte, de façon à minimiser l'effet de tout courant de fuite. On a mesuré la linéarité de la sortie avec une modification de l'angle d'inclinaison effectuée selon un mode de réalisation illustré, à plus de 99,9 % dans une plage d'angles d'inclinaison de - 50 à + 50·.

Patent CA-2358149-A1 (CA)
Inventor: WALLINGFORD ERROL E
IPC: B61C15/12
Filed: 2001-10-01
Abstract: A control system for an AC electric motor on an electric vehicle deactivates the motor when the control system senses a shift in the mechanically coupled transmission extending between the motor rotor and the wheels. The transmission shift condition may be detected by comparing the current transmission ratio to the immediately preceding measured transmission ratio. If these differ, the motor is electrically deactivated. Two successive measures of the same transmission ratio in a range corresponding to a valid transmission ratio indicate the end of a transmission shift hence permitting the safe resumption of excitation of the motor based on the then current measured rotor speed.
