He holds five patents that showcase his innovative approach to electronic key telephone systems and communication circuits. His work has significantly impacted the way communication systems operate, particularly in the realm of telephone technology.
Latest Patents
One of Alan Bloch's latest patents involves electronic key telephone systems. This system allows each station set to generate a continuous, current-modulated digital data stream that carries information about the status of pushbutton-actuated switches. The data stream is transmitted over standard four-wire cable to a station card in the key service unit, which decodes the data and implements the requested services. The system also generates a voltage-modulated digital data stream for controlling various functions, including speakerphone connections and background music transmission.
Another significant patent by Bloch relates to a communication circuit that provides two channels between a control unit and a terminal device. This innovative four-conductor circuit arrangement allows for simultaneous power feed and bi-directional signaling without interference. The voltage modulator circuit in the control unit transmits voltage pulses over the four conductors, which are then received by a data receiver in the terminal unit. This design enhances the efficiency of communication systems, particularly in key telephone systems.
