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. 11,857,328.

Summary of the Inventive Concept

An adaptable active electrode system designed for high-security, disaster relief, extreme weather, high-altitude, and high-humidity environments, providing robust and reliable bio-potential signal sensing.

Background and Problem Solved

The original patent disclosed an active electrode component with a closed-loop unit-gain amplifier and chopper modulation, which is limited in its ability to operate in specialized environments. The present inventive concept addresses this limitation by adapting the active electrode component for specific, narrow markets or unique operational environments.

Detailed Description of the Inventive Concept

The inventive concept comprises an active electrode component with an integrated amplifier component and a shield, wherein the integrated amplifier component is adapted to operate at frequencies above 100 kHz to minimize electromagnetic interference in high-security environments. In disaster relief settings, the active electrode component generates an input signal, which is transmitted to a remote monitoring station via a wireless communication link. For extreme weather conditions, the integrated amplifier component features a temperature-compensated gain stage, and the shield is adapted to withstand environmental stressors. In high-altitude environments, the active electrode component operates at low power consumption to minimize battery drain. In high-humidity environments, the active electrode component features a hydrophobic coating and an integrated amplifier component operating at frequencies above 50 kHz to minimize noise interference.

Novelty and Inventive Step

The new claims introduce novel adaptations of the active electrode component for specific, narrow markets or unique operational environments, which were not contemplated in the original patent. The inventive step lies in the combination of the original patent's closed-loop unit-gain amplifier and chopper modulation with the specialized features and adaptations for high-security, disaster relief, extreme weather, high-altitude, and high-humidity environments.

Alternative Embodiments and Variations

Alternative embodiments may include using different types of amplifiers, such as operational amplifiers or instrumentation amplifiers, or incorporating additional components, such as filters or signal conditioners, to further enhance the signal quality. Variations may include adapting the active electrode component for other specialized environments, such as underwater or space exploration applications.

Potential Commercial Applications and Market

The inventive concept has significant commercial potential in various industries, including healthcare, aerospace, defense, and environmental monitoring. The specialized active electrode systems can be used in a wide range of applications, from medical devices for high-security environments to disaster relief equipment and extreme weather monitoring systems.
