Latest Patents

Lezotte's latest patents include a "Line Level Signal Measuring Device" and a "Data Communications Network Testing System." The Line Level Signal Measuring Device is designed to measure the power of analog signals on telephone lines within a data communications network. This device features a selection circuit that couples a chosen analog signal from one of the telephone lines to a measuring circuit. It utilizes a full-wave rectifier and a low pass filter to process the selected signal, which is then conveyed to multiple open-loop comparators. Each comparator generates a binary signal indicating whether the selected signal exceeds a predetermined power level. The device visually indicates line signal power through light-emitting diodes, with a blanking circuit to disable the LEDs during rapid signal level changes. Additionally, a self-testing circuit is included to ensure the functionality of the measuring device.

The Data Communications Network Testing System serves as a comprehensive testing facility for data communications networks. It incorporates modulators and demodulators at various sites, including central and intermediate locations. The system's hubbing site testing units connect to respective host modems, allowing for effective communication and testing. A configuration control circuit generates signals that identify the testing unit's location, while a validation circuit ensures accurate responses to command characters. This innovative system enhances the reliability and efficiency of data communications networks.
