His work has been instrumental in enhancing communication systems, particularly in the detection of alerting signals.

Latest Patents

Battista's latest patents include a "Method and system for detecting at a selected station an alerting signal." This invention describes a method and apparatus for detecting a dual tone alerting signal in the presence of speech. The system is designed to initiate the transfer of special service information on a telephone line. It features two channels for separately detecting each tone, with mechanisms for comparing the signaling energy around one of the tones with the energy in a selected weighted guard band portion of the voiceband. This comparison allows for a determination of whether a tone is present or not. The apparatus also includes timing circuitry that uses a pulse signal formed from the coincidences of tone detection in each channel to ascertain the presence of the dual tone alerting signal.

Another significant patent is the "Adaptive signal receiving method and apparatus." This invention pertains to a tone receiver suitable for use in a telephone system. It adaptively narrows its amplitude sensitivity range for valid tone signals on a per-call basis, improving signal echo rejection and reducing spurious noise talkoff. A programmed digital signal processor implements the preferred embodiment, which increases the lower amplitude signal threshold based on the amplitude of the first signal received.
