  • Patent number: 11385612
    Abstract: Systems and methods for setting up and operating a motor control system are provided. Such systems and methods can include a parent device that includes a digital library of control commands and a child device. A child device can transmit a unique identification code to the parent device and the parent device can identify, from the digital library, a group of control commands specific to the child device using the unique identification code, generate an address for the child device, and transmit a copy of the address to the child device for storage thereon. The parent device can transmit a control signal that includes the address and one of the control commands from the first group to the child device and, responsive thereto, the child device can perform an action when the address matches the copy of the address stored on the child device.

  • Patent number: 11049678
    Abstract: A magnetic float switch is provided. The magnetic float switch can include a housing configured to float in a liquid, response circuitry located inside the housing, an internal chamber located inside the housing, a float state indicator housed within the internal chamber, and an actuating arm housed outside the internal chamber and coupled to the response circuitry. In operation, when a position of the housing changes so as to indicate an increasing level of the liquid, the float state indicator can move within the internal chamber from a first position to a second position to initiate a magnetic force between the float state indicator and the actuating arm so as to actuate the actuating arm from an inactive position to an active position. Then, when the actuating arm is in the active position, the response circuitry can initiate a response to the increasing level of the liquid.

  • Patent number: 11008738
    Abstract: A pump control system receives inputs from a low level fluid level sensor, a high level fluid level sensor, and/or a temperature sensor. Based on inputs from the sensors, and in response to sensed trouble conditions, duplex pumping or pump specific simplex operation is restricted based on past and present pump current draws. Furthermore, using the temperature sensor and a temperature sensor output device, the temperature of the sump environment can be monitored at will from a remote location.

  • Patent number: 10079567
    Abstract: A system monitors physical characteristics of or near a motor shaft, such as strain, temperature, voltage, and/or stress. The sensors can sense or measure these characteristics and transmit the measured values wirelessly to a remote user, who can monitor the motor shaft for signs of inefficiency or malfunction. Furthermore, the system can support communications between the remote user and a controlling element of the motor to monitor and adjust the motor shaft to operate with greater efficiency and safety.
