Nicholas L. DiSalvo has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 7400479
    Abstract: Resettable circuit interrupting devices, such as GFCI devices, that include a reset lock-out mechanism are provided. The reset lock-out mechanism prevents the resetting of electrical connections between input and output conductors if the circuit interrupting mechanism used to break the connection is non-operational or if an open neutral condition exists.
    Type: Grant

  • Patent number: 7400477
    Abstract: Resettable circuit interrupting devices, such as GFCI devices, that include reverse wiring protection, and optionally an independent trip portions and/or a reset lockout portion are provided. The reverse wiring protection operates at both the line and load sides of the device so that in the event line side wiring to the device is improperly connected to the load side, fault protection for the device remains. The trip portion operates independently of a circuit interrupting portion used to break the electrical continuity in one or more conductive paths in the device. The reset lockout portion prevents the reestablishing of electrical continuity in open conductive paths if the circuit interrupting portion is non-operational, if an open neutral condition exists or if the device is reverse wired. Methods for ensuring a reset lock out state before shipment are provided.

  • Patent number: 7378927
    Abstract: Resettable circuit breakers having an independent trip mechanism and a reset lockout are provided. The trip mechanism operates independently of the fault protection operations, and the reset lockout prevents the resetting of the circuit breaker if the fault protection is non-operational or if an open neutral condition exists.

  • Patent number: 7372678
    Abstract: Resettable circuit interrupting devices having self-test and non-resettable or limited resettable power interrupting systems are provided. The permanent power interrupting system activates when a circuit interrupting device is no longer capable of operating in accordance with applicable standards governing such devices or the device is no longer capable of operating in accordance with its design characteristics.

  • Patent number: 7187526
    Abstract: A resettable circuit interrupting device such as a GFCI that is immune to the problem of reverse wiring and, therefore, has load-line terminals that can be interchangeably connected to either at least one load or to a power source. Regardless of how the load-line terminals are connected, the resettable circuit interrupting device operates properly and retains leakage current fault protection. The circuit interrupting device includes an interrupting portion disposed within the device configured to cause electrical discontinuity in either the phase and/or neutral conductive paths between the line side and the load side upon the occurrence of a leakage condition. A reset portion disposed at least partially within the device is configured to initially establish or, after the detection of a leakage current fault, reestablish electrical continuity between the load and the line.

  • Patent number: 7164102
    Abstract: A self heating thermal protector located in close proximity to a remotely located incandescent light fixture for controlling the flow of current to the lighting fixture by measuring the rate of heat flow from a dedicated heat source. Current is permitted to flow to the lighting fixture when the temperature of the self heating thermal detector is sufficient to avoid deterioration of electrical components such as plastic parts and wire insulation in the associated fixture. The thermal detector interrupts the flow of current to the associated fixture when the temperature of the self heating thermal protector increases to a temperature that is not safe.
