Patent number: 11796426Abstract: An HVAC system is monitored or tested using a tube with a measurement instrument in the tube. The tube is connected to an HVAC system and an output of the HVAC system is measured using the measurement instrument. The tube is connected between the HVAC system and a volume to be conditioned. A reading of the measurement instrument is noted while the tube is connected between the HVAC system and volume. The volume is disconnected from the tube and a valve is connected to the tube. The valve is adjusted until the reading of the measurement instrument is approximately the same with the valve as when the volume was connected. A setting of the valve is noted and then used to test the HVAC system in the future or to test other HVAC systems simulating the same load.Type: GrantFiled: July 30, 2021Date of Patent: October 24, 2023Assignee: Energy Quest Technologies Inc.Inventor: Dwayne M. Benson

Patent number: 7960934Abstract: A fault-tolerant position feedback filter may be used in an actuation control system to limit the authority of a first position signal, should the first position signal become erroneous, and thereby prevent a postulated runaway condition of an acuator. The filter includes a difference function, a limited integrator, and a summer. The difference function supplies a first position error signal representative of a mathematical difference between a first position signal and a combined position signal. The limited integrator supplies an integrated position error signal that is limited in magnitude to a predetermined limit. The summer supplies the combined position error signal that is representative of a mathematical sum of the integrated position error signal and the second position signal.Type: GrantFiled: September 23, 2008Date of Patent: June 14, 2011Assignee: Honeywell International Inc.Inventors: Dwayne M.

Patent number: 7884566Abstract: A system and method of implementing servomechanism control without rate feedback is provided. A position feedback signal is filtered using a non-linear lead-lag filter that has a variable frequency response to thereby generate a compensated position feedback signal. A position error signal is generated from a position command signal and a sensed position signal, and the frequency response of the non-linear lead-lag filter is varied in response to the position error signal. A compensated position error signal is generated from the commanded position signal and the compensated position feedback signal. The compensated position error signal is at least selectively filtered using a non-linear integral filter that has a variable gain to thereby at least selectively supply a filtered position error signal. The gain of the non-linear integral filter is varied in response to the compensated position error signal.Type: GrantFiled: May 15, 2008Date of Patent: February 8, 2011Assignee: Honeywell International Inc.Inventors: Steve Abel, Dwayne M.

If the EMA has experienced a fault, a fault-based position limit and a fault-based rate limit of the EMA are determined, based on the fault. A design position limit and a design rate limit of the EMA are supplied. An updated position limit of the EMA is determined based on at least the design position limit and the fault-based position limit, and an updated rate limit of the EMA is supplied based on at least the design rate limit and the fault-based rate limit.Type: GrantFiled: July 22, 2008Date of Patent: January 25, 2011Assignee: Honeywell International Inc.Inventors: Raj M.
