Publication number: 20220319178Abstract: Systems and methods for monitoring, optimization, and control of pool/spa equipment using video analytics are provided. A camera system in communication with a microprocessor monitors a pool/spa environment, identifies objects of interest in the pool/spa environment, classifies the objects of interest, and identifies scenarios and/or learned behaviors of objects utilizing video analytics. The analytics can include object detection in combination with tracking algorithms in order to precisely locate objects of interest within the video frames. Further image classification and scene labeling algorithms may be used to classify the object in order to define its attributes. Once processed, the system can transmit alerts or commands to pool/spa users and devices to modify the operation thereof based on the identified attributes of the objects of interest.Type: ApplicationFiled: May 1, 2020Publication date: October 6, 2022Applicant: Hayward Industries, Inc.Inventors: James Carter, Gregory Fournier, Jason Davila, Arthur W. Johnson, III, Louis Pereira, Troy Renken, Nagaraj B. Jayanth, Kevin L. Potucek

Patent number: 8605393Abstract: A compressor monitoring system includes current and voltage monitors, current and voltage averaging modules, a control module, and a switch. The current monitor measures a current drawn by a motor of a compressor. The current averaging module generates first and second average current values based on the current measured by the current monitor. The voltage monitor measures a utility power voltage. The voltage averaging module generates first and second average voltage values based on the voltage measured by the voltage monitor. The control module selectively generates a fault signal when a first ratio is greater than a first predetermined threshold and a second ratio is less than a second predetermined threshold. The first ratio is based on the first and second average current values. The second ratio is based on the first and second average voltage values. The switch deactivates the motor when the fault signal is generated.Type: GrantFiled: July 16, 2012Date of Patent: December 10, 2013Assignee: Emerson Climate Technologies, Inc.Inventors: Nagaraj B. Jayanth, George Ramayya

Patent number: 8604737Abstract: A three-phase electric motor of a compressor receives first, second, and third phases from a three-phase power supply. A method for protecting the motor includes, using a line break protector, disconnecting the motor from only the first phase in response to a temperature being greater than a predetermined temperature threshold. The method also includes measuring a first current flowing through the line break protector, and determining a current value based on the first current independent of current in the second and third phases. The method further includes disconnecting the motor from the first, second, and third phases in response to the current value being less than or equal to a predetermined threshold.Type: GrantFiled: January 10, 2013Date of Patent: December 10, 2013Assignee: Emerson Climate Technologies, Inc.Inventors: Nagaraj B. Jayanth, Wayne R. Warner

Patent number: 8390221Abstract: A system for protecting a three-phase electric motor of a compressor, the motor receiving first, second, and third phases from a three-phase power supply, the system including a single-phase line break protector, a first current sensor, and a control module. The single-phase line break protector disconnects the motor from the first phase in response to a temperature being greater than a predetermined temperature threshold. The first current sensor measures a current through the single-phase line break protector. The control module determines a current value based on the measured current, and disconnects the motor from the second and third phases in response to the current value being less than or equal to a predetermined threshold.Type: GrantFiled: September 23, 2011Date of Patent: March 5, 2013Assignee: Emerson Climate Technology, Inc.Inventors: Nagaraj B.
