He holds three patents that showcase his innovative approach to solving complex problems in communication technology. His work has had a lasting impact on the industry, particularly in the area of key telephone systems.

Latest Patents

One of Kerman's latest patents is the "Key Telephone Call Signalling Circuit." This invention is directed towards a calling circuit that efficiently controls the connection of two different audio signal sources to a single audio signal transmission path. It allows for broadcasting audio signals over a telephone set loudspeaker while also managing the energization of indicators in the telephone set and at the main control circuit. Notably, this circuit utilizes only four conductors to connect the telephone set with the main control circuit, two of which serve as power supply conductors that can also support other circuits.

Another significant patent is the "Pulse Counting Circuit." This counting circuit generates an electrical representation corresponding to the number of pulses in multiple pulse trains, with each pulse train containing a maximum of ten pulses. The circuit begins counting only after receiving a first pulse train with more than a preselected number of pulses. It then counts each pulse in subsequent pulse trains for a predetermined number of pulse trains. This invention is particularly useful in key telephone dial pulse signaling apparatus, functioning as a register circuit that is not affected by false pulses generated when lifting the handset.
