  • Patent number: 11177102
    Abstract: A power relay is controlled by the presence of Volatile Organic Compounds that are often emitted by outgassing from electronic components during overheat and failure conditions. The relay housing contains a standard power relay of single pole single throw (SPST) or a multi-pole double throw relay depending on the application. A micro VOC integrated circuit is placed within the housing allowing access to ambient air through ports in the side of the relay.

  • Patent number: 11159157
    Abstract: A circuit is provided for converting alternating current power into direct current (DC) power and providing a digitally stable ground for operation of a processor-based device. Embodiments of the circuit include a transformer isolating (e.g., via galvanic isolation) a primary side from a secondary side of the circuit. A controller (e.g., a pulse width modulation (PWM) controller) on the primary side directs a switching circuit to selectively permit current flow through a primary side of the transformer to a first ground node on the primary side. A secondary winding of the transformer sources a rectified DC output relative to a second ground node that is isolated from the first ground node. In some cases, compensation on the secondary winding side provides isolated feedback to the controller via an optical isolator or some other circuit. The controller directs the switching circuit based at least in part on the error correction feedback and input from an auxiliary winding of the transformer.

  • Patent number: 11152793
    Abstract: A resonant transformer connected between a ground terminal and elevated terminal draws current from the earth's electric field through a primary winding of the transformer. An impulse generator applies a high voltage impulse to the primary winding of the resonant transformer to cause current to flow from the ground terminal through the primary winding. The flow of current through the primary winding of the resonant transformer induces a current in the secondary winding, which may be converted and filtered to a usable form, e.g. 60 Hz AC or DC.
