Patent number: 7307402Abstract: A method of charging an electrochemical generator having a plurality of electrochemical cells. The method includes the step of charging the plurality of electrochemical cells such that the total voltage of the generator reaches a predetermined voltage level, followed by the steps of selecting a particular electrochemical cell and charging the particular electrochemical cell to its respective maximum voltage, such that the cathode(s) of the particular electrochemical cell is(are) restored to a fully-charged state. Once it has been restored to its fully-charged state, the particular electrochemical cell is allowed to discharge itself down to a nominal voltage. Each of the plurality of electrochemical cells of the generator is selected and charged to its respective maximum voltage in turn, according to a predetermined selection sequence.Type: GrantFiled: July 19, 2004Date of Patent: December 11, 2007Assignee: Avestor Limited PartnershipInventors: Michel Parent, Philippe Gagnon, Jean-Pierre Vaillancourt

Patent number: 6654482Abstract: The method for locating a mobile unit relatively to an intermittent lighted beacon consists in calculating, on the basis of data concerning the mobile movement, the position of the discrete scatterer on the linear barrette obtained by a point by point subtraction of two linear images of the same image field, one wherein the beacon is alight and one wherein it is not alight, and the derivative of the position. On the basis of said data, the distance separating the beacon thus represented and a mark related to the mobile unit is calculated, and the beacon angular position relative to said mark linked with the mobile.Type: GrantFiled: May 3, 2000Date of Patent: November 25, 2003Inventors: Michel Parent, David Gualino
