Patent number: 11473799Abstract: A flow control device is configured to control fluid flow in an HVAC system. The flow control device includes a valve, an actuator configured to open and close the valve, and one or more sensors. The flow control device further includes a fault detection and correction agent configured to receive data from the one or more sensors, analyze the data according to a set of rules, and detect whether one or more faults have occurred. In response to detecting a fault, the fault detection and correction agent is configured to either operate the actuator to open or close the valve or initiate a corrective action to be taken by another device in the HVAC system.Type: GrantFiled: August 10, 2020Date of Patent: October 18, 2022Assignee: JOHNSON CONTROLS TYCO IP HOLDINGS LLPInventors: Sudhi R. Sinha, Donald R. Albinger, Youngchoon Park, Karl F. Reichenberger, John T. Pierson, Vineet Sinha

Patent number: 10975851Abstract: An actuator system includes a shaft hub having a shaft and one or more rotation arms coupled to the shaft, one or more shape memory alloy springs coupled to the one or more rotation arms, and as a voltage source configured to apply a voltage to the one or more shape memory alloy springs. The voltage causes the one or more shape memory alloy springs to change in size or shape, thereby applying a force to the one or more rotation arms and causing the shaft hub to rotate. The actuator system also includes a processing circuit configured to receive an indication of a desired incremental rotation for the shaft hub and apply a voltage corresponding to the desired incremental rotation to the one or more shape memory alloy springs, causing the shaft and the shaft hub to rotate about a central axis.Type: GrantFiled: April 1, 2019Date of Patent: April 13, 2021Assignee: Johnson Controls Technology CompanyInventors: Kirk P. Henderson, John T. Pierson, Julie Ahl, Kevin A. Weiss
