ALEXANDRIA, Va., Feb. 24 -- United States Patent no. 12,558,538, issued on Feb. 24, was assigned to Novocure GmbH (Baar, Switzerland).

"Using staggered changes in amplitude and frequency to ameliorate electrosensation during treatment with alternating electric fields" was invented by Mor Ben-Tov Kuperberg (Haifa, Israel), Yoram Wasserman (Haifa, Israel) and Michael Shtotland (Haifa, Israel).

According to the abstract* released by the U.S. Patent & Trademark Office: "When transducer arrays (i.e., arrays of electrode elements) are used to apply alternating electric fields (e.g., TTFields) to a subject's body, the subject may experience electrosensation. This electrosensation can be ameliorated by (a) increasing the amplitude of the field in...
