Latest Patents

Ingalls' patent, titled "Isolator circuit for use with frequency sensitive switching circuit," addresses the need for efficient load management in response to control signals. The isolator circuit is engineered to work with a switching circuit that energizes a ballasted load based on a control signal of a preselected frequency. This control signal is superimposed on AC power circuits supplying the load. The design includes a triac that conducts AC power to the load through a circuit featuring an impedance element and a series resonant LC network, which is tuned to the frequency of the control signal. The isolator circuit itself consists of multiple series-connected parallel resonant LC circuits, each tuned to block specific control signals, while a series choke effectively blocks spurious signal voltages.
