Latest Patents

His most recent inventions include the "Electronic Tone Ringer with Distinctive Signaling Circuitry" and a general "Electronic Tone Ringer." The former is a sophisticated device designed to provide distinctive ringing capabilities through dual oscillators, allowing users to select from four distinct tones and modulation rates. This innovation includes features like formattable inputs that enable either frequency shift or amplitude modulation, significantly enhancing the performance of the ringing signal. In the frequency shift mode, two related fundamental frequencies are generated, while the amplitude modulation mode allows for a single frequency to be toggled at the selected modulation rate. All tones created are suitable for driving an electromagnetic acoustic transducer.

The general "Electronic Tone Ringer" demonstrates his ability to create technology responsive specifically to ringing signals on a telephone line, differentiating itself by being unresponsive to dialing pulses and other signals. This ringer can be powered directly from the telephone line or from an external DC supply, equipped with a digital integration and detection arrangement to discern valid ringing signals from invalid ones.
