IPC: H02J7/00
Filed: 2000-11-06
Granted: 2002-06-11
Abstract: The present invention relates to a charging method capable of extending battery lifetime. Especially, the invention is appropriately used for lead-acid battery, in which the voltage of the battery during the charging process is detected through a detection protection circuit and the charging current value for the battery is adjusted by using an adjustment control circuit when the battery is charged. When the battery is gradually and fully charged, the battery voltage is increased and the charging current is gradually decreased by the adjustment control circuit along with the voltage variation of the battery such that as the charge quantity of the battery is closer to saturation, the charging current is closer to zero. According to the invention, by using the manner of stepless varied current, charging can be completed under the condition without damaging the battery so as to further extend battery lifetime.

Title: An optical switch having a planar waveguide and a shutter actuator
Inventor: AL-HEMYARI KADHAIR
IPC: G02B26/08
Filed: 2000-11-22
Granted: 2002-09-21
Abstract: An optical switch having an input waveguide and two output waveguides separated by and disposed around a trench. The input waveguide and a first output waveguide have respective optical paths defined by their respective cores; those optical paths (and cores) being coaxial with each other. Those waveguides are also separated by a trench having a medium provided therein that has a refractive index different from that of the waveguides. The input waveguide and first output waveguide are separated by a distance defined by the trench and that is insufficient to affect the transmission characteristics of an optical signal propagating from the input waveguide to the first output waveguide, even though the optical signal experiences different refractive indices as it propagates across the trench from the input waveguide to the first output waveguide. The input waveguide and a second output waveguide are arranged generally on the same side of the trench such that an optical signal passing from the input waveguide to the second output waveguide does not completely traverse the trench. Thus, even though an optical signal passing from the input waveguide to either of the first or second output waveguide encounters different refractive indices, the distance over which the optical signal must travel between the waveguides is small enough so as to not affect the optical transmission characteristics of that signal.
