Patents by Inventor John K. Krenzer

John K. Krenzer 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: 11961383
    Abstract: An actuator in an HVAC system is provided. The actuator includes a motor and a drive device. The drive device is driven by the motor and coupled to an HVAC component for driving the HVAC component between multiple positions. The actuator further includes a processing circuit. The processing circuit is coupled to the motor and configured to transmit control signals to operate the motor to drive the HVAC component between a first position and a second position, monitor temperature data received from one or more temperature sensors, determine that the temperature data does not meet an expected performance criterion and transmit an alarm signal.
    Type: Grant

  • Patent number: 11079732
    Abstract: A method for updating heating, ventilation, or air conditioning (HVAC) devices is provided. The method includes receiving an update package at a first HVAC device of a plurality of HVAC devices via a network. The update package includes an identification of a plurality of device models and a plurality of software updates. The method includes determining that a device model for the first HVAC device is identified by the update package and in response to a determination that the device model for the first HVAC device is identified by the update package, extracting a first software update corresponding to the device model for the first HVAC device from the update package and installing the first software update on the first HVAC device. The method includes transmitting the first update package to a second HVAC device of the plurality of HVAC devices via the network.
