Latest Patents

One of Ballard's latest patents is a telephone line interface circuit. This circuit is designed for coupling digital or analog data signals to a telephone line. It features a direct coupled transistorized circuit with three different impedance conditions: on-hook, off-hook, and loop-test. This design allows for data transmission regardless of the on-hook or off-hook status of the associated telephone sets, enabling seamless communication even when the telephone sets are in use. The circuit supports a frequency spectrum ranging from d-c to frequencies in the data-over-voice range. Additionally, the variable bridging impedance ensures that the drive impedance remains adequate during on-hook ringing, eliminating the need to disconnect the circuit during ringing or testing.

Another significant patent involves a co-channel communications system that permits the simultaneous transmission of a digital data signal alongside a communications medium signal, such as telephone voice or television video. This system converts data signals into very low multifrequency signals that span the communications bandwidth. By utilizing multiple frequencies for each data signal, the system can suppress the signal level of the data relative to the communications medium signal, ensuring no perceptible degradation of the telephone voice or television video. Synchronous detectors for each transmitted frequency, including harmonic frequencies, are employed to recapture and regenerate the transmitted data signals.
