Latest Patents

One of his remarkable inventions is the "Electronic Tone Ringer with Distinctive Signaling Circuitry." This device offers distinctive ringing capabilities by utilizing two oscillators, enabling the selection of four tones and four modulation rates. The technology provides options for generating tones with either frequency shift or amplitude modulation modes, allowing for customizable sound outputs. In frequency shift mode, alternating tones are created based on a predetermined frequency ratio. Conversely, the amplitude modulation mode produces a single frequency that can be switched on and off at the selected modulation rate. This innovation is designed to drive an electromagnetic acoustic transducer efficiently.

Another noteworthy patent is the "Electronic Tone Ringer," which responds specifically to ringing signals on a telephone line. This invention skillfully distinguishes valid ringing signals from dialing pulses or other signals, enhancing its effectiveness. It can be powered directly from the telephone line or through an external DC supply and incorporates a digital integration and detection arrangement for accurate signal recognition. This ringer also utilizes dual oscillators, similar to his previous invention, allowing for the selection of four frequencies and modulation rates.
