The array is connected to a load and power is drawn from the series array.

A second charging current is then selectively applied to various of the cells in the series array, topping up each of the cells in the series array.

A method for determining the physical locations (64) of devices (60) located on a series connected network (50).

When one of the cells reaches a predefined maximum voltage, the series charging current is ceased.

Wires electrically connect the light emitting cells to one another to thereby form a serial array of the light emitting cells.

Its cost-effective system architecture uses a “daisy-chain” network topology, which allows system units to be located at any point on the network.

The two transistors are both connected to form a series network between positive (VDD) and negative (GND) voltage supply terminals.
