Latest Patents
One of his latest inventions is a wireless butt set designed for testing telephone lines. This device includes a base station that connects to the tip and ring leads of a line under test and can be operated by a wireless telephone handset. The handset is designed to nest with the base station, creating a hand-held integrated butt set assembly. This configuration allows a craftsperson to control the test set directly or remotely using the handset's controls. The internal circuitry of the base station can enter a high impedance line-monitoring mode without going off-hook, responding to a single click of the talk switch on the handset, and goes off-hook with a double-click.
Another significant patent is a method for testing call waiting and caller ID functionality of telephones. This innovation enhances the control software of a central office-installed ringback test device, enabling a craftsperson to test the operability of caller identification and call-waiting services without needing another technician's participation. The system maintains the trunk circuit in a monitored state, allowing the SASS to place a return call to the calling number, effectively testing the line's capabilities.
