    Abstract: A system for optimally recharging a battery cell while powering a device connected to the battery pack, in which an electronic switch (22) connects a battery pack power-output either to the battery cells (12) or to a second power-input contact (20). When not recharging, the battery-pack power-output contact (16) is connected to the battery cells (12), thereby powering the device from the cells. When recharging via a charging unit, the battery pack's power-output terminal is uncoupled from the cells (12) and coupled to a power source of the charging unit, thereby powering the device from the charging unit. At the same time, a voltage is supplied to the battery cells (12), thereby recharging them. The switching may be activated by a voltage supplied by the charging unit to a temperature monitoring thermistor (24) in the battery pack. In this way, the battery pack's power output may be automatically switched whenever it is placed in the charging unit.

    Abstract: A circuit configuration for introducing bias in balanced lines capable of high frequency operation comprises top (30H) and bottom layers (30E) formed on a semiconductor substrate (30). The circuit includes two balanced metallized lines (33,32) positioned on the substrate (30). Each metallized line has a serpentine line (34,35,36,37) configuration connected thereto. The space between the lines is a virtual ground (31). The serpentine line configurations are congruent with elements on the substrate layers (30H,30E) to provide a completed circuit. The elements are coupled to a central metallic area (39), which in turn is coupled to a bias line (38) through an open-line stub (50), which extends beyond the virtual ground (31) and which provides equal capacitive coupling to the balanced lines (33,32). In this manner, the balanced line configuration includes capacitors and inductors which are symmetrically distributed and which provide resonance at the designed operating frequency. The bias line (38) thus formed is RF grounded due to the virtual ground (31) and is disconnected from the actual balanced lines (33,32).
