With a total of 3 patents to his name, Kamke's work has had a lasting impact on the industry.

Latest Patents

One of Kamke's latest patents is a charge regulator for a radio telephone. This electronic device is designed to connect to a variable-level power source and includes a rechargeable power source that is recharged in response to the application of operative power. The device features a constant charge current regulator that converts operative power of a constant voltage into a constant current for recharging the power source. Additionally, when the rechargeable power source is fully charged, the application of operative power can be reduced.

Another significant patent is an apparatus and method for simulating high battery temperature in a rechargeable cell. This device utilizes a control signal generated by a voltage control circuit to disconnect the rechargeable cell from the charging system when a predetermined voltage is reached. It is particularly useful for lithium-based chemistry cells, which require a different charging regime than nickel chemistry cells. The device can be retrofitted to existing rechargeable batteries, allowing them to be charged using current charging systems.
