Patent number: 10571394Abstract: A control system and associated methods for an air treatment system. In one aspect, the present invention provides a control system and method for controlling blower speed as a function of separately determined smoke and dust concentrations. In one embodiment, the control system and method provides a variable delayed between changes in motor speed to address undesirable rapid changes between speeds. In another aspect, the present invention provides a system and method for calibrating a sensor to provide more uniform operation over time. In yet another aspect, the present invention provide a system and method for calibrating motor speed to provide more consistent and uniform motor speed over time. The present invention also provides a system and method for tracking filter life by as a function of time, motor speed and/or a sensed variable, such as particulate concentration in the environment.Type: GrantFiled: January 5, 2017Date of Patent: February 25, 2020Assignee: Access Business Group International LLCInventors: Thomas A. Niezgoda, Thomas J. Leppien, Gregory K. Evans

Patent number: 9808754Abstract: An air treatment system having an improved control system. The control system may include a dynamic “dead front” display that varies the display based on mode of operation. The display may include capacitive touch sensors and include an array of capacitive film segments or traces integrated into the display. The control system may include a self-contained electronics module that can be tested and calibrated before installation in the ATS. A dust sensor assembly may be integrated into the electronics module. The front cover may be attached with a mechanical attachment at the top and a magnetic attachment on the bottom. The ATS may include a filter retainer assembly with a rotating clip configured to perform in a cam-like manner to firmly clamp the particulate filter and carbon filter in place.Type: GrantFiled: May 5, 2015Date of Patent: November 7, 2017Assignee: Access Business Group International LLCInventors: William T. Stoner, Jr., Terry L. Lautzenheiser, Steve O. Mork, Sean T. Eurich, Matthew J. Norconk, Gregory K. Evans
