Latest Patents

Langsdorf's latest patents include an "Arrangement and method of achieving a dial pulse muting function" and a "Power fail monitor and transfer circuit." The dial pulse muting function is designed to prevent the sender outpulsing from being heard by disabling the sampling of the transmit to the network side of the trunk circuit. This innovative approach reduces the need for additional equipment by implementing the function within the trunk circuit rather than the line circuit. Furthermore, it utilizes integrated circuit chips instead of relays, resulting in a more compact and reliable arrangement. The power fail monitor and transfer circuit provides four metallic transmission loops from subscribers on the private branch exchange to dedicated trunk lines at the central office. This system utilizes the central office battery as the transmission medium, ensuring that incoming calls can ring directly to private branch exchange subscribers. The design also includes features to automatically provide metallic transmission loops during power failures, preventing interruptions in telephone conversations during power restoration.
