System for controlling charging of secondary battery

To provide a system for controlling the charging of a secondary battery (battery), which is capable of keeping an initial charging / discharging characteristic of the battery in consideration of a change in environmental temperature and deterioration of the battery with elapsed time. An ordinary charging portion for performing a first charging control specified to stop the charging at a charge level less than a full-charge level is used in combination with a refresh charging portion for performing a second charging control specified to stop the charging at a charge level more than the full charge level. After the charging by the ordinary charging portion is continuously repeated by a specific number of times, for example, ten times, the next charging is performed by the refresh charging portion. The cut-off voltage used for the ordinary charging portion and refresh charging portion is determined by correcting a reference voltage VO on the basis of an environmental temperature TAO detected by an environmental temperature detecting portion. The deterioration of the battery is corrected on the basis of a reference full-charge voltage, an initial full-charge voltage Vmax(1), a present full-charge voltage Vmax(n), an initial maximum battery temperature Tmax(1), and a present maximum battery temperature Tmax(n).

Power supply system and electronic device

An output from a generator section is controlled by a current converter section to be a constant current. Charging and discharging of a power storage section is controlled by a charge / discharge control circuit. Thereby, even in a case where a current value required by a load is high, the case can be dealt with in the manner that, while an output current from the generator section is being maintained constant, the output from the generator section and an output from the power storage section can be caused to function in cooperation with each other. Further, charging and discharging of the power storage section can be performed by a simplified device.

Device and method for the packet based access of classical ISDN/PSTN subscribers to a switching system

The invention relates to a device and to a method for the packet-based access of classical ISDN / PSTN subscribers to a switching system. The convergence of packet-based networks and TDM networks leads to a situation where classical analogous and ISDN subscribers and private branch exchanges have to be accessed via packet-based transmission methods. Especially for the case of a failure of, for example, the subscriber terminals TNE or switching system-related devices or intervening communication paths, it must be made sure that substitute connections can be made and stable connections can be maintained. This problem is solved by the present invention by providing a peripheral adaptation device, integrated into the periphery of the switching system, and being suitable for the adaptation of the messages used on the interface between subscriber terminal and peripheral adaptation device, to the requirements of the plurality of peripheral devices associated with the TNE port. Furthermore, software functions are provided for treating the failure of, for example, the subscriber terminal, the one peripheral adaptation device or one of the associated peripheral devices of the switching system. The interaction of said failure treatment software functions controls the substitute connection and restart of failed peripheral devices, peripheral adaptation devices and communication paths to subscriber terminals.

Flash unit

In a flash circuit of a flash device, a Zener diode (37) is connected to a tap point (23f) located at an intermediate position of a secondary coil of an oscillation transformer (23). The oscillation transformer (23) and an oscillation transistor (22) constitutes an oscillation circuit. A potential at the tap point (23f) changes proportionally to a voltage charged in a main capacitor (41). When the main capacitor (41) is charged up to a set voltage, the Zener diode (37) conducts a Zener current, which activates a stopping transistor (38) and thus deactivates the oscillation circuit. When a flash charge switch (51) is turned on, an end of a light guide portion of a charge condition indicator (60) protrudes out of a lens-fitted film unit. When the main capacitor (41) is charged up to the set voltage, a light emission element starts lighting, and the light from the light emission element is projected from the end of the light guide portion.
