Latest Patents
One of his latest patents is a switching device for connecting a data transmission system. This invention describes a data transmission system that includes a switching circuit, enabling the connection of a tributary modem to a control modem via the public switched network. The switching occurs when data transmission on the leased network is no longer possible due to a line failure. The circuit can connect either the permanent leased line or the switched network to the control modem's receiver. It features a narrow pass-band filter and detector that are permanently connected between the reception side of the switched network and the control modem receiver. When the tributary modem answers a call from the control modem, it sends a tone ahead of the data message, which corresponds to the frequency of the pass-band filter. This innovative approach allows for seamless switching to maintain connectivity.
Another significant patent is a method and system for controlling a network of modems. In this invention, a Data Terminal Equipment (DTE) can control the attached modems by transmitting command messages over the data path and analyzing report messages supplied by the modems in return. Each command message is identified by a specific header, allowing for efficient communication and control of remote modems.
