Patent number: 11467145Abstract: An engine assembly includes an internal combustion engine and a carbon monoxide (CO) sensor unit. The CO sensor unit includes a CO sensor controller including a CO sensing circuit configured to detect a level of CO and a shutdown circuit. The shutdown circuit is configured to receive a detected level of CO and calculate a trailing window average of the detected level of CO. The trailing window average includes an average of the detected level of CO over a predetermined sampling window. The shutdown circuit is further configured to determine whether to initiate a shutdown of the internal combustion engine based on at least the calculated trailing window average and a predetermined trailing window average threshold and initiate the shutdown of the internal combustion engine based on determining that the trailing window average exceeds the predetermined trailing window average threshold.Type: GrantFiled: July 16, 2021Date of Patent: October 11, 2022Assignee: Briggs & Stratton, LLCInventors: Ryan Janscha, Austin Baeten

Publication number: 20220090545Abstract: A generator includes an internal combustion engine, a proximity sensor structured to detect a distance value indicative of a distance between the generator and an object, and a controller. The controller is configured to receive a first distance value from the proximity sensor corresponding to the distance between the generator and the object. Upon determining that the first distance value is less than a predetermined minimum distance value, the controller is configured to initiate an alarm. The controller is further configured to receive a second distance value from the proximity sensor corresponding to the distance between the generator and the object. Upon determining that the second distance is less than the predetermined minimum distance value, the controller is configured to initiate a shutdown of the generator.Type: ApplicationFiled: December 1, 2021Publication date: March 24, 2022Inventors: Mark Willer, Ryan Janscha, Brandon Nigh, Austin Baeten

Patent number: 11220964Abstract: A generator including an internal combustion engine having an exhaust outlet, a proximity sensor structured to detect a distance value indicative of a distance between the exhaust outlet and an object, and a controller. The controller includes a proximity circuit structured to receive the distance value from the proximity sensor and a shutdown circuit. The shutdown circuit is structured to receive the distance value from the proximity circuit, determine whether to initiate at least one of an alarm and a shutdown of the generator based on the distance value and a predetermined distance value minimum, and initiate at least one of the alarm and the shutdown of the generator based on determining that the distance value is less than the predetermined distance value minimum.Type: GrantFiled: September 11, 2019Date of Patent: January 11, 2022Assignee: Briggs & Stratton, LLCInventors: Mark Willer, Ryan Janscha, Brandon Nigh, Austin Baeten
