  • Calibration and use of mechanical relay at zero cross
    Patent number: 10535482
    Abstract: This disclosure describes systems, methods, and apparatus for determining a relay delay for a relay of a relay device used to switch AC power to and from a load. The relay delay can be pre-determined as a model or polynomial including variables for temperature and age, such that the switching instructions can be sent to the rely a relay delay before a zero crossing of the AC signal that the relay is switching, and where the relay delay accounts for temperature and age of the relay in real time or near real time.

  • Isolated dimming circuit
    Patent number: 10362653
    Abstract: This disclosure describes methods and apparatuses for controlling an isolated diming circuit. An exemplary circuit may include a voltage input device, a noninverting operational amplifier in electrical communication with a optoelectric coupler, an optoelectric coupler incorporating emitting and receiving photodevices, an inverting operational amplifier in electrical communication with the optoelectric coupler, a voltage output device in electrical communication with the inverting operational amplifier, and a lighting device.
