Abstract: Battery charging in a battery charging system (BCS) involves measuring an output voltage of a battery connected to the BCS and determining an output voltage type of the battery. The battery is also evaluated to determine a condition of the battery for accepting a charge. Based upon the evaluation the BCS performs can automatically initiate a charge cycle for the battery in accordance with the battery output voltage type which has been determined. The BCS can also trigger an indication that the battery is not in condition for accepting a charge. A range of output charging voltages is produced using a transformer, and a switch network.

Abstract: Systems/methods for operating a solar charger system. The system comprises: preventing, by a first circuit, damage to the solar charger system when a reverse polarity connection exists between a solar panel and the solar charger system; preventing, by a second circuit, damage to the solar charger system when a reverse polarity connection exists between the battery and the solar charger system; preventing, by a third circuit, damage to the battery when a temperature of a surrounding environment exceeds a pre-defined value while the battery is being charged by the solar charger system; and preventing, by a fourth circuit, back-feed from the battery without any voltage drop or loss while the battery is being charged by the solar charger system.

Abstract: Cellular communication network is managed by receiving at a computing device certain data specifying geolocation information of one or more user equipment in communication with one or more nodes of the cellular communication system. The computing device identifies a disruption in receipt of the periodic geolocation information, and uses the received geolocation information to at least partially define a location of a peripheral edge of a communication dead zone. The peripheral edge information is used to facilitate a dynamic modification or control of the cellular communication network and/or the user equipment.
