Latest Patents

Tompkins holds a patent for a cordless battery charger, which serves as a rechargeable emergency portable battery charger for starter motor storage batteries. This innovative device includes a sealed lead acid battery as its energy source. An oscillator circuit connected to a transformer generates 3 V in its secondary, which is rectified and added in series to the 12 V of the self-contained battery. This configuration provides the necessary charging current to a starter motor storage battery. The connection is made via a cigarette lighter socket in the disabled vehicle, ensuring ease of use. Current is limited to approximately 4 amps to prevent excessive heat dissipation. Additionally, a voltage-sensing circuit determines if the voltage of the starter storage battery is below approximately 6 V or is shorted to ground, further enhancing safety. The device also features a switch that allows for recharging the self-contained battery and connecting any 12 VDC device directly to it. An ammeter monitors current flow, while a light-emitting diode circuit indicates when charging is complete.
