This technical disclosure describes improvements that would be readily apparent to a Person Having Ordinary Skill In The Art (PHOSITA) when considered in combination with the foundational architecture disclosed in U.S. Patent No. 11,856,939.

Background and Problem Solved

The original patent, 'Smart cover bug deterrent', addressed the issue of bugs entering air data probes when aircraft are grounded. However, the original design had limitations in terms of optimizing insect repellent release and detecting insect presence. The new invention builds upon the original concept by introducing temperature control units, sensors, micro-pumps, and scheduling controllers to create a more efficient and effective bug deterrent system.

Novelty and Inventive Step

The new claims introduce novel features such as temperature control units, sensors, micro-pumps, and scheduling controllers, which are not present in the original patent. These advancements provide a significant improvement in bug deterrent capabilities and air data measurement accuracy, making the new invention non-obvious and novel compared to the original patent.

Alternative Embodiments and Variations

Alternative embodiments of the invention could include using different types of sensors, such as optical or acoustic sensors, to detect insect presence. Additionally, the micro-pump could be replaced with a different dispensing mechanism, such as a spray nozzle or a wicking system. The scheduling controller could also be integrated with other aircraft systems, such as navigation or weather monitoring systems, to optimize insect repellent release.

Potential Commercial Applications and Market

The enhanced smart cover system has significant commercial potential in the aerospace industry, particularly for aircraft manufacturers and operators. The improved bug deterrent capabilities and air data measurement accuracy can lead to increased safety, reduced maintenance costs, and improved overall performance. The invention could also be applied to other industries, such as agriculture or environmental monitoring, where accurate air data measurement is crucial.
