Patent number: 11790751Abstract: A detector device includes a light source disposed within a chamber, a sensor disposed within the chamber, a compensator circuit electrically coupled with the sensor, and a controller. The controller is operable to receive a sensor signal generated by the sensor, determine a compensation factor to adjust the sensor signal, and generate a compensation offset signal based on the compensation factor. The controller is further operable to output the compensation offset signal to the compensator circuit to produce a compensated sensor signal as an adjustment to the sensor signal, energize the light source, monitor the compensated sensor signal with respect to an alarm limit, and trigger an alarm event based on the compensated sensor signal exceeding the alarm limit.Type: GrantFiled: December 30, 2022Date of Patent: October 17, 2023Assignee: CARRIER CORPORATIONInventor: Matthew J.

Patent number: 10203302Abstract: A method of manufacturing an electrochemical sensing system is provided. The method includes forming a sensor with a first sensing element disposed on a sensor, the first sensing element configured to detect a target gas, disposing a second sensing element on the sensor, the second sensing element configured to detect the target gas, and coupling a protective feature to the second sensing element, the protective feature configured to prevent non-target gases from contacting the second sensing element. The sensor is configured such that if the first sensing element generates a current exceeding a first threshold current value and the second sensing element does not exceed a second threshold current value it is determined that the first sensing element is contaminated and a restoration protocol is performed on the first sensing element.Type: GrantFiled: August 2, 2016Date of Patent: February 12, 2019Assignee: CARRIER CORPORATIONInventors: Matthew J.
