Latest Patents

One of Zofan's notable patents is the "Annunciator Circuit for Elevator Systems." This invention provides a highly reliable annunciator circuit that is immune to spurious signals generated in an elevator environment. The circuit employs an input condition verification network that works in conjunction with low true logic two-bit inputs. It performs switching only when those inputs fall below a preset control value, resulting in enhanced performance. Additionally, the volume control over the piezoelectric output, which develops a chime or gong sound, is achieved through a variable impedance control that is adjustable on-site.

Another significant patent is the "Cathodic Protection of Structures." This method, system, and apparatus carry out cathodic protection of structures by evaluating true current and true voltages at the counter electrode through an integration procedure. This procedure is timed in conjunction with the crossover times of the originating a.c. input to the power source. The system may also employ an IR drop-free potential measurement using a reference electrode. To improve performance, difference networks are utilized to develop the difference between the signals of one channel and the parallel channel, effectively canceling spurious noise phenomena. The system features a hierarchical control system that operates with a soft start procedure to enhance reliability.
