Solution Overview
Problem
Existing CO detectors primarily rely on local alarms and do not effectively communicate dangerous CO levels to remote monitoring devices, particularly in environments like aircraft cabins, where timely remote notification is crucial for operator safety.
Innovation Solution
A CO sensing system that includes a CO detection device connected to a remote monitoring device, such as an aircraft's multifunctional display, allowing for continuous monitoring and remote communication of CO levels, with features like a reset/retest actuator, heating element for temperature compensation, and adjustment for air pressure changes, enabling alert signals and control of auxiliary devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If CO detectors use local alarms only, then the device complexity is low, but the loss of information occurs because remote monitoring capability is absent
Solution Approach 1:
The patent introduces a remote monitoring device as an intermediary that receives data from the CO detection device and provides alerts to operators. This mediator architecture allows the detection device to focus on sensing while the remote device handles communication and alerting, resolving the contradiction by adding remote monitoring capability without requiring the detection device itself to be overly complex.
2Measurement precision
If CO detection device is placed in harsh environmental conditions, then the measurement precision may improve by being closer to the source, but the reliability deteriorates due to temperature and pressure effects
Solution Approach 1:
The patent applies parameter changes by introducing temperature and pressure compensation mechanisms. The detection device includes sensors that monitor environmental parameters and adjust the CO detection readings accordingly. This allows the device to maintain reliable operation in harsh environments while preserving measurement precision through real-time parameter adjustment.
Solution Approach 2:
The patent implements beforehand cushioning by providing pre-calibration and compensation algorithms that account for expected environmental variations. The system is designed in advance to handle harsh conditions through built-in compensation mechanisms, ensuring reliability is maintained even when placed close to CO sources in challenging environments.
3Loss of time
If alarm signal is provided locally only, then the ease of operation is high, but the loss of time occurs because remote operators cannot be notified promptly
Solution Approach 1:
The patent segments the alerting function from the detection function. The detection device handles CO sensing and data transmission, while the remote monitoring device handles alert generation and operator notification. This segmentation enables timely remote notification through automated digital communications while keeping the detection device itself simple and easy to operate.
4Reliability
If heating element is added for temperature compensation, then the reliability improves in cold environments, but the use of energy increases
Solution Approach 1:
The patent implements periodic action by using the heating element intermittently rather than continuously. The heating element is activated only when temperature compensation is needed to maintain reliable detection performance in cold environments. This periodic operation maintains detection reliability while significantly reducing overall energy consumption compared to continuous heating.

AI summary
A sensing device for detecting the presence of carbon monoxide in a selected space of concern and communicating with a remote monitoring device is provided. The sensing device comprises (a) a detection device configured to sense the presence of carbon monoxide in the selected space of concern, (b) a monitoring device remote from the detection device, for communicating information to an operator, and (c) the detector in circuit communication with the monitoring device, to transmit information from the detection device to the monitoring device that is related to carbon monoxide in the selected space. According to one preferred embodiment, the sensing device is designed for an aircraft. The remote monitoring device is the multifunctional display of the aircraft cockpit. In addition, in a preferred embodiment, a reset/retest actuator is connected with the multifunctional display, and is in circuit communication with the detection device. The reset/retest actuator is selectively actuated from the multifunctional display to send a reset/retest signal to the detection device, to reset the detection device, and to initiate operation of the detection device to repeat its carbon monoxide detection process and provide a signal related to the level of carbon monoxide detected by the detection device. Moreover, in a preferred embodiment, a heating element is provided that is proximate to the carbon monoxide detection component. The heating element is selectively actuated to heat the air space about the carbon monoxide detection component. Also, an adjustment device associated with the output of the CO detection device, for adjusting the output of the detection device in response to a signal related to the air pressure in the selected space of concern. These features are particularly useful in a detection device for an aircraft, where ambient temperatures may drop to levels that can adversely affect the performance of the detection device, or where pressure changes in the aircraft may affect the sensitivity of the detection device.
