Patent number: 11916370Abstract: A circuit interrupter device for selectively connecting a source of AC power from a line side to a load side of the circuit interrupter device includes a controller powered from a source of AC power from a line side. The controller initializes a self-test and determines whether the self-test was successful. The controller outputs a self-test result signal. An electrically-held relay of the device, which is in communication with the controller and is powered from the line side, stays in an OFF state until the self-test result signal indicates the self-test was successful, and enters an ON state if the self-test was successful. When in the OFF state, a load side of the circuit interrupter device is not in electrical communication with the source of AC power, and when in the ON state, the load side is in electrical communication with the source of AC power.Type: GrantFiled: May 28, 2021Date of Patent: February 27, 2024Assignee: Leviton Manufacturing Co., Inc.Inventors: Michael Ostrovsky, John LiBretto

Publication number: 20230089554Abstract: Multi-pole and single-pole circuit breakers include a housing and a reset lockout mechanism disposed within the housing. The reset lockout mechanism disables electrical communication between line and load terminals of the circuit breaker if a predefined condition exists. Some circuit breakers include a single actuator, transition between ON and OFF states, and are capable of performing test functions. The test functions may involve testing AFCI and/or GFCI functions of the circuit breakers. The test functions may be performed when the circuit breaker transitions from an OFF state to an ON state. Some circuit breakers including a reset lockout mechanism may be powered only on its line side. Some circuit breakers provide an electrical indication when they are in the OFF state.Type: ApplicationFiled: December 1, 2022Publication date: March 23, 2023Inventors: Michael Ostrovsky, Michael Kamor, Alfred J.

Publication number: 20230053431Abstract: In aspects of the present disclosure, a circuit interrupter includes a housing, a conductive path, a switch which selectively interrupts the conductive path, sensor(s), memory, and a controller within the housing. The sensor(s) measure electrical characteristic(s) of the conductive path. The memory stores an arc detection program that implements a machine learning model and includes a field-updatable program portion and a non-field-updatable program portion, where the field-updatable program portion includes program parameters used by the non-field-updatable program portion to decide between presence or absence of an arc fault. The controller executes the arc detection program to compute input data for the machine learning model based on the sensor measurements, decide between presence of an arc event or absence of an arc event based on the input data, and cause the switch to interrupt the conductive path when the decision indicates presence of an arc event.Type: ApplicationFiled: May 18, 2022Publication date: February 23, 2023Inventors: Yazhou Zhang, Michael Ostrovsky, Ankit Sanghvi, Adam Kevelos

Patent number: 11464096Abstract: A zero-crossing detection method, and devices incorporating the method, enable a selectively enabled bias to pull-up a zero-crossing signal, thereby enabling monitoring of the zero-crossing of both half-cycles of the alternating current (AC). This improves synchronization of the device in noisy environments and enables the detection of dimming problems during either half-cycle. Aspects can detect improper dimmer firing events on either polarity of the power cycle and restore normal dimmer operations when needed.Type: GrantFiled: September 28, 2018Date of Patent: October 4, 2022Assignee: LEVITON MANUFACTURING CO., INC.Inventors: Michael Ostrovsky, Ozgur Keser

Patent number: 11240897Abstract: Two-wire dimmer operation includes controlling conduction of power to a lighting load. In one aspect, based on a conduction angle adjustment, power supply voltage is monitored and a maximum conduction angle is established based thereon. In another aspect, a dimming level signal is received and a dimming level for a dimmer is set based on the received dimming level. The dimming level signal indicates a desired dimming level for a dimmer, and a maximum value for the dimming level signal is based on a dimmer power supply voltage. In yet another aspect, based on detecting an adjustment to increase a conduction angle of a dimmer, the conduction end angle is increased and the conduction start angle is also increased. This results in a net increase in the conduction angle for controlling operation of the dimmer.Type: GrantFiled: December 17, 2020Date of Patent: February 1, 2022Assignee: LEVITON MANUFACTURING CO., INC.Inventors: Michael Ostrovsky, Alan Neal, Alfred Lombardi
