Latest Patents

One of Douglas K. Charles's notable inventions is a sophisticated battery charger. This device automatically manages the charging process, operating independently of individual battery designs or temperature variations. The charger periodically interrupts the charging current to measure the resistance-free voltage of the battery at defined intervals. By analyzing the changes in this voltage over time during an initial constant current period, the device determines a reference voltage specific to each battery. This innovative system ensures that the charging current is adjusted to avoid significant overcharging, thereby enhancing battery longevity and safety.

Another significant patent revolves around the manufacturing of titanium anode substrates. In this process, sponge titanium powder is compacted—preferably through roll compaction—achieving a density of about 60% to 80% of solid titanium metal. The compacted material undergoes heat treatment in a vacuum environment at temperatures ranging from 500°C to 750°C, before being cooled and quenched to create a high-quality substrate ideal for use in electrolytic processes.
